Of all the major Supreme Court decisions of the 20th century, there’s one that stands out for shaping the way we live and the physical contours of the American landscape: Village of Euclid v. Ambler Realty Co., which affirmed that cities and towns could institute zoning as a way to regulate all growth and development.

The case came out of a suburb just east of Cleveland in the 1920s, when a real estate company was denied the use of land for industrial development; appeals went all the way to the Supreme Court, which backed the village of Euclid, and in so doing provided constitutional blessing to the basic concept of zoning seen in color-coded maps to this day—homes in one part of town, commercial and retail in another, and manufacturing and industrial uses in yet another.

At the time, Justice George Sutherland made the comment that a factory shouldn’t be in a residential area any more than “a pig in the parlor.” He also said apartment buildings shouldn’t be mixed in with single-family homes, saying the presence of residential density was like welcoming in a “parasite.”

That was in 1926, and this year, scholars and policymakers are marking the 100th anniversary of the Euclid decision, as zoning is being reevaluated across the country. Some 33 states have passed reforms to allow more density in zones once reserved for single-family homes only, and to promote the concept of mixed-use, blending housing with shops, restaurants, and workplaces all within walking distance—basically the kind of neighborhoods that Euclid made illegal. The critique suggests that American zoning is outdated and hasn’t kept up with the times—and, perhaps most important, that its application has made housing unaffordable and racially segregated.

For those reasons, zoning is “starting to be at least chipped away at by state and even local legislation,” said William Fischel, professor emeritus at Dartmouth College, in an interview on the latest episode of the Land Matters podcast.

Fischel is author of the book Zoning Rules, published in 2015 by the Lincoln Institute and cited in the early pages of Abundance by Ezra Klein and Derek Thompson, who blame excessive regulation for blocking housing and infrastructure projects. He is also author of The Homevoter Hypothesis, an explanation of how mostly single-family homeowners have used zoning and environmental regulations to preserve the status quo.

Zoning emerged out of concern for public health and the need to organize cities to accommodate manufacturing and residential development following the invention of the automobile, says Fischel, who was the keynote speaker at a symposium at George Mason University earlier this year cosponsored by the Mercatus Center, the Pacific Legal Foundation and the Journal of Law, Economics and Policy.

[00:00:05] Anthony Flint: Welcome to Episode 2 of Season 7 of the Land Matters Podcast. I’m your host, Anthony Flint. Of all the major Supreme Court decisions of the 20th century, there’s one that stands out for shaping the way we live and the physical contours of the American landscape: Village of Euclid v. Ambler Realty Company, which affirmed that cities and towns could institute zoning as a way to regulate all growth and development.

The case came out of a suburb just east of Cleveland in the 1920s when a real estate company sought to use their land for industrial development. The town said no, we want that area to be residential. Ambler Realty sued and the case made it all the way to the Supreme Court. The justices backed the Village of Euclid and in so doing provided constitutional blessing to the basic concept of zoning that we all see in color-coded maps to this day, homes in one part of town, commercial and retail in another, and manufacturing and industrial uses in yet another.

At the time, Justice George Sutherland made the comment that a factory shouldn’t be in a residential area any more than a pig in a parlor. He also said apartment buildings shouldn’t be mixed in with single-family homes, saying the presence of residential density was like welcoming in a parasite. Strong words from Justice Sutherland, to be sure, but from that point on, thousands of municipalities followed the template of separating uses and spreading them around. That was in 1926.

Understandably — not everybody might be aware of this –but scholars and policymakers and others are actually marking the 100th anniversary of the Euclid decision. It’s not so much a celebration but a reconsideration of the landmark ruling, looking at the effect that’s had 100 years later and essentially reassessing what has come to be known as Euclidean zoning itself.

Some 33 states have passed reforms to allow more density in zones once reserved for single-family homes only, and to promote the concept of mixed use, blending housing with shops, restaurants, and workplaces all within walking distance — basically the kind of neighborhoods that Euclid made illegal. The critique suggests that American zoning is outdated and hasn’t kept up with the times, and perhaps, most important, has made housing unaffordable and racially segregated.

With us today to unpack all of this is William Fischel, a professor emeritus at Dartmouth College and author of the book, Zoning Rules, published in 2015 by the Lincoln Institute. That volume is cited in the early pages of Abundance by Ezra Klein and Derek Thompson, who blame excessive regulation for blocking housing and infrastructure projects. Fischel is also the author of The Homevoter Hypothesis, an explanation of how mostly single-family homeowners tend to resist any changes because they’re worried about property values. We’ll discuss that in just a bit.

I should add that Fischel was the keynote speaker at a symposium at George Mason University earlier this year, co-sponsored by the Mercatus Center, the Pacific Legal Foundation, and the Journal of Law, Economics, and Policy, which was featured in Bloomberg City Lab and Land Lines Magazine. He’s a great friend of the Lincoln Institute and served with distinction for many years on the board of the organization. Bill Fischel, welcome to the Land Matters Podcast.

[00:03:31] William Fischel: Thank you, Anthony. Good to be here.

[00:03:33] Anthony Flint: Let’s start toward the beginning of all this, the advent of zoning in the US. One of the fun facts I discovered while researching some of this is that zoning was imported — along with the delicatessen — from Germany after the turn of the last century. Why and how did zoning come to be the go-to policy for guiding growth and development in this country?

[00:03:55] William: Edward Bassett, considered to be the father of zoning: he and other people went to Germany. Germany was the place you went for advanced civilization. In the twenties before World War I, Germany was the high point of culture and science and social science as well. Bassett and some other people went to Germany and studied zoning. He came back with the idea that you could have comprehensive zoning.

Now, comprehensive zoning in Germany turned out was different from comprehensive zoning in the United States. That is, the United States massaged it quite a bit. In Germany, the idea was to split the city into something like thirds, like a pie wedge, so many pie wedges or pizza wedges, where businesses would be in the center, a logical place for them, and along each pie wedge would live the people who worked in that particular industry.

This was to save transportation costs, so you could go back and forth, so all the workers going to the same place could go to the same place at home, regular commuting instead of going in circles and so forth. If you were in the metal industry and there was a metal factory, the metal workers and their bosses would live outside. Now, the bosses lived in nicer homes, maybe a little farther out. It wasn’t like there was great intermixing, but there was this segregation by occupation. That didn’t go anywhere in the United States. We had company towns and things like this where people lived around the factory and so forth.

The zoning that occurred in the United States was really separating residential from commercial from industrial. I grew up in Bethlehem, Pennsylvania, where they had a great big steel mill. Workers clustered around the plant. A lot of people walked to work because they couldn’t afford a car, or it was just more convenient. The clustering was natural there. The separation of uses, commercial from industrial and so forth, was a feature of American zoning from the get-go. I think that was what made it fairly attractive.

[00:05:51] Anthony Flint: Now, there was also some thinking in the progressive era at the time about the health impacts. Can you talk a little bit about that, this idea that congestion and tenement houses and housing of any kind being close to a smelter or a tannery and all of that?

[00:06:08] William Fischel: There was certainly that. The big progressive move actually had occurred in the late 19th century that made cities much more livable. They got decent drinking water, and they dug sewers, got the waste out of the neighborhoods, at least. Those were great advances in public health.

Once that was fixed, people, as people do, want to go to the next best thing, and that is, “Let’s not have these noxious fumes from our factory.” If you’re a steelworker, you endure it during the day, you’d rather not endure it at night. You’d like to be a little farther away from the blast furnaces. That was part of the story. This was an issue that could be fixed by distance.

The plant operators in Pittsburgh got together and said, “It’s so damn polluted, people don’t want to live here. We can’t recruit executives to come from other cities because it’s so polluted.” They actually collectively, along with the state of Pennsylvania, restricted the plants themselves, reducing pollution, relocating them so they weren’t so close to the residents, and more or less cleaned up Pittsburgh by the standards of the time. That was a big accomplishment.

The thing that brought on zoning was the desire for single-family homes. That was usually not a problem when there was simply distance involved. What upset that equilibrium was the invention of the automobile. The automobile, and most importantly, the derivatives of the automobile, something called the motor truck and a jitney bus — a jitney bus was a small bus almost always privately operated that just cruised around neighborhoods, picked up people, and took them to work or took them shopping or whatever. It’s like an airport bus now today in its capacity, not in its comfort. The cheap car and the cheap truck and cheap motor bus made industry and apartment dwellers footloose. They didn’t have to walk to work anymore. The industry could put parts of their business, maybe all of their business, out in much cheaper land in the suburbs.

The industry was suffering from congestion by the docks or by the railhead, competing with other businesses. They say, “Let’s move the warehouse out in the suburbs here. We’ve got this tract of land.” Put up a warehouse or put up some storage place or put up a back office operation. They could do that now that they could truck things from one place to another pretty easily. They didn’t have to be stuck to rail lines or trolley lines. That’s what made the single-family house vulnerable. It couldn’t be cured by distance anymore. It had to be cured by something else.

Eventually, developers in California led the charge here. Everybody was moving to California in the early 20th century, emptying out the Midwest. Developers wanted single-family homes. They wanted that single-family house in the suburbs, out in Pasadena and outside central Los Angeles.

The developers in Southern California faced up to this problem and said, “We need to adopt some collective action.” They got the city of Los Angeles to let them establish their own residential districts. It was really the first zoning laws. The problem that came up in Los Angeles was that industry was having a problem finding a place to locate.

The classic case, Sebastian v. Hadacheck … Mr. Hadacheck had a brick factory. He had it downtown Los Angeles. Residential development occurred around his brick factory. You’d think they would have smelled it first, but there they went. They established one of these residential districts and said, “You’ve got to get out of here. Sorry, Hadacheck. You can’t stay here anymore. You’re in the wrong zone.”

Hadacheck moves away, a couple of miles away, and it’s open land. He builds up his brick factory. He has a brick truck. He’s got that Henry Ford derivative invention of a truck. He can move his bricks. He’s happy as a clam until somebody develops a residential area right next to him. Same thing, deja vu all over again, as Yogi Berra would say. He gets zoned out. He takes this case to the California Supreme Court. The California Supreme Court says, “Too bad. First in time is not first in right.” If you’re making something like a nuisance or a brick factory, they’re not pleasant to be next to. He takes it to the US Supreme Court. The US Supreme Court says, “Too bad. Sorry, Hadacheck. You have to move.”

Los Angeles turns around and says, “We have a problem here. Our problem is we got lots of residential land, but we have no place for them to work. We have no place for them to put brick factory. We can’t do anything if we can’t have our business.” They invent the exclusive industrial zone.

On the other side of the river, no houses allowed, at least no new houses allowed. Industry is free to locate there. Once they do that, they have something that looks comprehensive. Just before they do that, New York comes up with it’s comprehensive zoning. My friend, Edward Bassett, writes the zoning law, pretty much, and separates commercial and apartments and so forth in all five boroughs. New York City is a big place, even bigger than Los Angeles back then. Those two events are the birth of zoning.

[00:11:36] Anthony Flint: Now, there’s another theme underpinning some of this in zoning, and that is racial segregation. How did zoning end up becoming a tool to set down the rules for who lived where?

[00:11:49] William: Modern zoning and zoning stemming from Euclid was not who lived where, but what you could do where. It wasn’t a matter of Jones and Smith have to live on this said street and Brown and White have to live on the other side. It was about residential versus commercial versus industrial, and always the size of that house and so forth.

The mix-up, the mash-up here, and I think people are understandably both confused and concerned by this, is that there’s a case before Euclid called Buchanan v. Warley. In Buchanan v. Warley, it started in the border states of the South: Maryland, Kentucky, Tennessee, and Missouri, and so forth. Prior to World War II, a lot of industry is starting to develop, partly generated by demand for US products from the outbreak of the war.

Lots of Black people are coming to these cities. They’re sick of being sharecroppers and being discriminated against, and so they move north to cities. The cities of the border south are quite unwelcoming to Black residents. They’re okay with them in their factories, but they want them to live in their own place. There’s no law that says that Black people have to live in this section and white people live in that section, so they make a law that says exactly that. The law says, “In this area, wherever there are majority whites located in a block, then Black people cannot live there, either rent or buy, except as servants.” This is really virtually an apartheid ordinance.

This law is taken to the US Supreme Court, Buchanan v. Warley, nine years before Euclid, hears the case. It takes a look at the 14th Amendment of the United States, which says life, liberty, and property shall not be denied them anyway. It says, “No, this violates the Constitution and strikes down the law unanimously.” Conservative, liberal, everybody in between says, “No, that will not fly.”

Some of the cities go and try and tweak it a little bit. They see this thing called zoning. Zoning comes in after this and doesn’t mention race or anything about the characteristics of people who might occupy. It just says use. It divides things up. There were residential zones. There were residential zones that allowed apartments. There were commercial zones. There were industrial zones. These zones, in ways that you’d look back at it and say, “It looks sensible.” The residential zones are along these loopy streets that you see in suburbs that were popular back then. The main drag is zoned for apartments.

What Euclid does mainly is says, “It’s okay to separate these uses. We’re not giving you standards as to how to separate them. We’re not telling you what the property is. You’re not telling us you can separate by race. We already struck that down.” Cities kept attempting it, and the courts, even the state courts in the South, were striking it down. It never got any real traction. Zoning, on the other hand, blasted out the gate once the Supreme Court said, “Okay.” The irony here is that developers now complain about the zoning regulations and so forth. Zoning was a developer idea.

[00:14:54] Anthony Flint: All of these threads continue to intertwine through the Great Depression and World War II, through the well- documented practice of redlining certain areas to be eligible for mortgages, the prevalence of racial covenants, on through with the development of places like Levittown and increasingly larger lots that only certain people can afford.

What’s so remarkable is that these rules got so locked in, as you point out, with the owners of primarily single-family homes buttressed by environmental laws and the growth management movement, at least since about 1970. Can you talk a little bit about why it was effectively defended for so long and, of course, continues to be, and that is this idea of nimbyism or not in my backyard?

[00:15:39] William Fischel: I’ve been studying zoning for 50 years. I looked at zoning and I thought it looked too restrictive from an economics point of view, but I said, “Why is this?” I needed to understand not just how zoning operated, but who was behind zoning. I looked around and was on the Hanover (New Hampshire) zoning board. I’m looking at who’s showing up at my meetings. They’re homeowners.

Asking myself, “Why are they going on about these proposed developments near their homes that look perfectly benign to me, better than most, and going on like the earth will end if this project gets done?” It hits me in a financial sense that these people, homeowners like myself, maybe like you, have a very large asset in their financial portfolio.

I’m thinking like an economist. This asset, unlike stocks that you might own, is not diversified. My pension fund is diversified. If General Motors goes south, Tesla will take up the slack, big deal, diversified portfolio. Most of my other assets, about half of my assets, I would estimate, are in my home. If that goes south, there’s no diversification. I can’t pick up my home and move it to another neighborhood. I can’t put my home up in parts and sell it to other parties to make a mutual fund out of it. I’m stuck with a very undiversified asset.

I developed the idea that homeowners are acute, overly, acutely aware of the risk, not just the value, the risk that their home endures because it’s in one place, in one industry, in one location, and they’ve got to defend it. They have to defend it more than you would think would be rational because they’re not just thinking about the expected outcome, they’re thinking about the risk. They show up at the zoning board and behave like they’re irrationally concerned when they’re not irrationally concerned. They’re NIMBYs. They’re not in my backyard.

Now, these people are not terribly effective until 1970. The environmental movement gives them a tool to run around me on the zoning board, to go to court and have the courts decide this. Now, the courts might be sensible places to do, but they take time. For developers, time is money. They’ve bought the land on a loan and they’ve got to pay interest. The bank is not waiting for them. They make compromises. “Oh, we wanted to have quarter-acre lots here. How about I make them half-acre lots or 2-acre lots or something like that?” Low density zoning because I can’t wait for you to decide.

Then lots of the environmental laws become really fussy about things like wetlands. Doubles the amount of land that is taken off the market where developers can’t go or they can’t go without conditions from the zoning board or the planning board to do it. Again, taking time, taking money to do it. This gets multiplied. The environmental movement is at the root of this. It’s not a crazy movement, but it’s taken to extremes by people who are not so much concerned about the environment as the value of their homes.

[00:18:34] Anthony Flint: Now that’s changing.

[00:18:35] William Fischel: I think eventually excessive success generates sometimes a collapse. I think that’s what we’re seeing now. I hope it’s a gentle collapse. I don’t want them to throw out all environmental laws. I don’t want them to fill in all the wetlands or disregard the important environmental issues. They’ve been taken to extremes and they’ve been abused by local groups.

What I’m seeing here is not simply state laws that say, “Towns, you have to pay attention to housing,” but also courts that are saying, “Hey, guys, this endless environmental invocations to stop development have to have an end.” It does have what economists would call an opportunity cost. That opportunity cost is housing and a stratified society and a stultified economy. That’s what the authors of Abundance have pointed out and saying, “We don’t have to be that way.”

One of the things that occasionally makes me happy to be in a diverse democracy is people occasionally say, “Yes, we have to change our ways.” I’m seeing people change their ways and changing their attitudes towards this. I don’t want to run back to 1916 and just get rid of zoning. I think the idea that we can just abolish zoning is very wishful thinking.

[00:19:48] Anthony Flint: A process where zoning is continually tweaked and revisited and an acknowledgement that times have changed, especially with affordability being so front and center.

[00:20:01] William Fischel: I don’t think if we abolished zoning, we would get rid of our racial problems by any stretch of the imagination. I think once you get the town manager or the city manager saying, “I’m sorry. We can’t fill out the ranks of the fire department because we can’t get people to move here,” that gets people’s attention after a while. The private sector has been complaining about that for a while.

Now I think there’s real traction of people feeling the consequences of this excessive fussiness about who your neighbors are that it’s starting to be at least chipped away at by state and even local legislation. I’ve been critical of my own town, but I’ll give my town a bit of credit. We have an infill development in process that allows single-family homes to be converted to two-family, even four-family homes in the neighborhoods. There is resistance, but it was generated entirely by the town council.

You present people with the facts and enough evidence, real-time evidence, sometimes they come around and say, “Yes, we do have to change our ways.” I’m encouraged. I’ve been retired from teaching for six years, but I’m happy to spread some of the hopefully good news of land use regulations that accommodate more people, outsiders, and a larger spectrum of the social and, of course, the racial spectrum that makes the United States an interesting place.

[00:21:17] Anthony Flint: What’s so interesting to me is just how these rules that most people don’t spend a lot of time thinking about really shape our society and how we live.

[00:21:28] William Fischel: One of the things I discovered on the zoning board is how naive, at least from our point of view, people are about zoning. Until something happens in the neighborhood, then they get well-informed. Then they understand what the rules are. I think enough things are happening from enough different points of view that some change is likely to happen. I don’t think it will be without rough spots, but I see the general trend as positive here.

[00:21:49] Anthony Flint: Bill Fischel, thank you so much for joining the conversation at Land Matters.

[00:21:54] William Fischel: You’re welcome.

[00:21:54] Anthony Flint: You can find more background on the Euclid case and Bill Fischel’s book, Zoning Rules, at the Lincoln Institute website, lincolninst.edu. Zoning has a special place in the history of the Lincoln Institute.

We actually had our own symposium on Euclid, if you can believe it, in 1986 on the occasion of the 60th anniversary of the decision, co-organized by Charles Haar and Jerold Kayden from Harvard, and led to the publication of Zoning and the American Dream: Promises Still to Keep, published in 1989. That book, in turn, was reviewed in Cite Journal, a publication of Rice University, under a headline that has to be one of the most clever in scholarly writing about land use: “Here’s Looking at Euclid.”

There’s an additional wonderful Henry George thread here as well. The lawyer for Ambler Realty, Newton Baker, succeeded Tom Johnson as mayor of Cleveland and was similarly a dedicated Georgist, alongside none other than John C. Lincoln, the founder of the Lincoln Institute, who was active as an inventor and entrepreneur in the Cleveland area around the turn of the last century.

One way or the other, we look at zoning and land use regulation, especially as it pertains to housing construction today, pretty much on a continual basis. After all, zoning is about land and we’re the Lincoln Institute of Land Policy. On social media, our handle is @landpolicy. Please go ahead and rate, share, and subscribe to Land Matters, the podcast of the Lincoln Institute of Land Policy. For now, I’m Anthony Flint signing off until next time.

Removing the Permanent Chassis Requirement for Manufactured Homes 

By Arica Young and Bennie Chang, Marzo 25, 2026

In 1974, Congress passed the National Manufactured Housing Construction and Safety Standards Act (HUD code), which requires manufactured homes to be built on a permanent steel chassis. A chassis is a 10-to 12-inch-deep metal frame under manufactured and mobile homes that enables easy transportation with a tow truck; however, it raises homes off the ground and creates difficulty adding a second story or basement. The requirement reflected past building norms and the fact that owners moved them frequently. Now, fewer than 5–7 percent of all manufactured homes are ever moved after initial placement. 

While the US Housing and Urban Development oversees the HUD Code and governs manufactured housing requirements, only an act of Congress can change the chassis requirement because of its Congressional origins. In late February 2026, the US Senate and House of Representatives approved legislation that would remove the requirement for manufactured homes to be built on a permanent steel chassis.  

What does chassis removal mean? 

Chassis removal is the process of removing the steel chassis from a manufactured home after the home is transported to its permanent site. With a chassis requirement change, owners could keep their chassis attached to the home, as with current policy mandates, or have it removed before home placement. Regardless, chassis would continue to transport manufactured houses to their placement location, and, if removed, the home manufacturers would likely reuse the chassis. The recycling and reusing of chassis, an expensive component of a manufactured home, would decrease material costs, allowing lower home prices. 

Chassis removal will not affect the stability of the manufactured homes, as stability rests on the foundation rather than on the chassis. Manufactured homes without chassis can continue to be placed on nonpermanent or permanent foundations, like site-built and modular homes. The placement requirements for installation would remain the same: Manufactured home foundations will continue to follow state and local building codes. However, if homeowners would like to get federally backed mortgages (like FHA, VA, and USDA), they would also have to continue to follow HUD’s Permanent Foundations Guide. 

How will chassis removal affect housing supply? 

While no studies have predicted how the proposed lifting of the requirement would change housing supply, chassis removal is expected to raise supply by lowering costs, increasing consumer demand, and expanding the overall availability of manufactured homes. According to the Niskanen Center, removing the chassis requirement could decrease manufactured home costs by $5,000–$10,000, up to 9 percent of the total average prices. With that reduced price point, the legal change could put homebuying within the reach of more people. 

In addition, changes to chassis requirements could prompt states and localities to reconsider zoning and land use restrictions that determine where manufactured homes can be placed. Currently, concerns about cohesive community design encourage bans on the homes. Chassis removal would allow the homes to be situated like site-built homes, allowing a more seamless integration into existing communities. This could lessen concerns about design and foster reform of land use ordinances. Such regulatory changes would expand supply by allowing manufactured homes in more areas. Further, the change would increase the types of manufactured homes constructed.  

Ultimately, the chassis debate is about whether federal rules written for a different era still make sense for today’s manufactured housing market, where roughly 95 percent of homes are never moved after their initial installation and become long-term residences. Removing the permanent chassis requirement would not change construction standards—homes would still have to meet the HUD Code, which calls for safe, installment compliant foundations; however, removing the requirement could expand what manufactured homes can be, where they can go, and who can afford them. If the projected cost savings materialize and the market responds with more design flexibility and broader acceptance by local jurisdictions, chassis policy reform could become a practical way to increase supply and widen access to stable homeownership, all while keeping the core promise of manufactured housing intact: delivering quality homes at lower costs.

Manufactured Housing State Policy Playbook Launch 

Mayo 27, 2026 | 10:00 a.m. - 4:00 p.m. (EDT, UTC-4)

Washington DC

Offered in inglés

Join the Lincoln Institute of Land Policy’s Innovations in Manufactured and Modular Homes Network (I’m HOME) and The Pew Charitable Trusts for the launch of a new state policy playbook focused on expanding manufactured housing opportunities across the United States. This event will introduce the playbook’s overarching policy recommendations and highlight how states can take meaningful action to increase housing supply, improve affordability, and modernize housing policy through manufactured housing.

The launch will bring together policymakers, practitioners, advocates, and researchers for a discussion of state-level strategies to support manufactured housing as an important part of the nation’s housing landscape. The program will be organized around three core policy areas: reforming zoning and land use policies for manufactured homes; replacing substandard housing with new and efficient units; and creating or updating financing programs that enable new home development using manufactured housing. Together, these themes will show how states can reduce regulatory barriers, support healthier and more energy-efficient housing options, and expand the tools needed to finance new development.

Registration opens April 15, 2026.

11:00 a.m.–12:00 p.m. ET  | The 2026 Trend Report: Emerging Trends and Signals (HPCC, Room 310AB)

We live in a world characterized by accelerating change and increased uncertainty. Planners are tasked with helping their communities navigate these changes and provide guidance on preparing for an uncertain future. However, conventional planning practices often fail to adequately consider the future, even while planning for it. Most plans reflect past data and current assumptions but do not account for trends emerging on the horizon. 

To create resilient and equitable plans for the future, planners need to incorporate foresight into their work. This presentation outlines emerging trends that will be vital for planners to consider and introduces strategies for making sense of the future while practicing foresight in community planning. By embracing foresight, planners can effectively guide change, foster more sustainable and equitable outcomes, and position themselves as critical contributors to thriving communities. The practice of foresight is imperative for equipping communities for what lies ahead.

SUNDAY, APRIL 26

10:30 a.m.–12:30 p.m. ET | Planning with Foresight (Room 250A-C)

Futures literacy is becoming increasingly important in planning. It is the skill that allows people to better understand the role the future plays in what they see and do. This involves imagining multiple plausible futures, incorporating future scenarios into our work, and planning with foresight.  

This interactive learning experience, presented in a learning lab format, focuses on applying strategic foresight in planning and serves as an essential learning lab for individuals dedicated to shaping a better future for their community.

1:00 p.m.–1:45 p.m. ET | Leading Cities Through Change—Mayors Panel (Room 420AB)

Local leaders will discuss innovations in planning, affordable housing, climate resilience, and public finance in the context of a rapidly changing political environment.  

Moderator and Speaker: Anthony Flint, Lincoln Institute of Land Policy

Speakers: 

  • Mayor Sheldon Neely, City of Flint
  • Mayor Christopher Taylor, City of Ann Arbor
  • Mayor David LaGrand, City of Grand Rapids

1:00 p.m.–1:45 p.m. ET | When the Cloud Drops—Planning for Data Centers (Room 410AB)

As the demand for digital infrastructure and artificial intelligence accelerates, communities are increasingly approached by data center operators seeking suitable sites. While marketed as drivers of economic growth, these facilities often carry significant costs that are not fully transparent during the siting process. Data centers require immense physical resources—land for large footprints, vast amounts of water for cooling, and energy that strains local grids—raising questions about sustainability and long-term resilience. They also may introduce frontline communities to new sources of pollution, increased truck traffic, and environmental justice concerns, yet these voices are often marginalized in opaque political and regulatory processes. Promised economic benefits, such as job creation and tax revenue, are frequently overstated or unevenly distributed, leaving cities to shoulder environmental burdens with limited community gain.  

This presentation convenes a diverse panel to unpack complex planning challenges such as critically assessing data center proposals, advocating for accountability, and elevating community priorities. By examining the trade-offs of siting decisions through the lenses of resource management, equity, and governance, you will leave with practical strategies to question assumptions, navigate political opacity, and build stronger negotiating positions to ensure decisions genuinely serve the long-term interests of municipalities and their residents.

2:00 p.m.–2:45 p.m. ET | Equitable Urban Planning for a Changing Climate (Room 410AB)

This presentation offers actionable strategies to help planners advance equitable policies that simultaneously address climate change, housing affordability, and economic inequality. A new Lincoln Institute Policy Focus Report, Planning in a Polycrisis, synthesizes responses from surveys of professional planners and policymakers working in cities across North America. It highlights emerging innovations and the trade-offs in effectively integrating these considerations into their work. Other constraints are caused by shifting political landscapes, limited funding, and deepening social vulnerabilities. However, these planners’ work also advances integrated, equity-driven urban climate planning, and their innovations form a framework for cities to move from ad hoc responses toward a long-term equitable climate urbanism.  

The report’s authors and practicing planners explore practical strategies to address the barriers and trade-offs cities face. The conversation sheds light on how climate and housing planning can co-adapt to counter rising socioeconomic vulnerability, with a focus on the most recent shifts in practice. Showcasing these examples aims to empower city leaders with specific recommendations and strategies for advancing a model of climate urbanism that responds to the demands of a polycrisis.

THURSDAY, MAY 28 (VIRTUAL)

1:30 p.m. – 2:15 p.m. ET | Navigating Uncertainty—Using Strategic Foresight for Action-Oriented Planning (Channel 2)

Planners are fielding more “what-if” questions than ever as residents and local officials cope with increasing uncertainty and rapid change. Scenario planning is a systematic approach to answering these questions and kickstarting conversations with stakeholders about possible futures and their implications for today’s better decisions. These foresight tools can help planners create more flexible, resilient strategies to achieve local goals, come what may.  

 This presentation highlights how the Chicago Metropolitan Agency for Planning (CMAP) is using horizon scanning and exploratory scenario planning to define a long-term vision (the Century Plan) in a large, complex metropolitan region composed of seven counties, 284 municipalities, and 8.5 million residents. CMAP is considering drivers of change and an understanding of regional systems—including transportation, natural resources, and the economy—to explore the grand challenges and strategic responses that should define the region’s next era. Presenters explore how these tools are bringing foresight into planning and discussions for bold regional action. Learn how CMAP engaged with elected leaders and other planners, and how you can use resources from state and regional agencies to encourage local officials to shift to a horizon-based mindset.

2:30 p.m. – 3:15 p.m. ET | Exploratory Scenario Planning for Brazil’s Public Lands (Channel 1)

Brazil’s Secretariat for Federal Assets (SPU), an agency within the Ministry of Management and Innovation in Public Services (MIG), collaborated with the Lincoln Institute of Land Policy to apply exploratory scenario planning (XSP) to federal land policy. The work supports the Imóvel da Gente (Property of the People) program, which positions federal land as a strategic asset for socioenvironmental development.  

Attendees will learn how futures thinking can be integrated into national policy frameworks with practical methods for designing participatory scenario planning processes in complex governance settings. The session will present strategies for engaging multiple agencies, fostering collaboration among jurisdictions, and embedding equity goals into long-term planning.  

Through the case of Brazil’s first XSP initiative, participants will explore tools for identifying drivers of change, developing plausible future scenarios, and translating scenario outcomes into actionable strategies. These approaches can help planners address uncertainty, adapt to shifting conditions, and create policies that are resilient and inclusive.  

The session emphasizes how collaborative, futures-oriented methods can strengthen institutional capacity, broaden participation, and ensure that land use policies serve diverse community needs. Attendees will leave with transferable strategies to support equitable, future-ready planning in their contexts.

How Zoning Won—and Why It’s Now Losing Ground

By Anthony Flint, Marzo 9, 2026

This article is reprinted with permission from Bloomberg CityLab, where it originally appeared.

Of all the society-shaping US Supreme Court decisions of the 20th century, from Brown v. Board of Education to Roe v. Wade and beyond, one lesser-known ruling has had the greatest impact on the American landscape—not only the physical character of growth and development, but how we live and work, the lengths of our commutes, and the affordability of homes.

In Village of Euclid v. Ambler Realty Co., a suburb just east of Cleveland barred a real estate company from using their land for industrial use; the developers sued and the case went all the way to the nation’s highest court, which affirmed that municipalities could impose zoning to organize development, as a police power.

The 1926 ruling—garnished by Justice George Sutherland’s comment that a factory shouldn’t be in a residential area any more than “a pig in the parlor”—gave constitutional blessing to the establishment of permissible uses on specific properties, seen in color-coded maps to this day. From then on, the template for the built environment was set: residential homes in one part of town, commercial and retail in another, and manufacturing and industrial uses in yet another.

Codifying this separation of uses led to the unique phenomenon of American suburban sprawl, essentially requiring the use of the automobile to get around as the areas for life’s functions spread further apart. It also locked in the hegemony of the single-family home, at the expense of more affordable multifamily housing.

Now, on the 100th anniversary of the decision, what has come to be known as Euclidian zoning is under siege. Progressives and pro-housing advocates in the Yes in My Backyard (or YIMBY) movement have joined defenders of property rights and free-market libertarians in declaring zoning as hopelessly outdated. This somewhat unlikely alliance blames local land use regulations for blocking apartment construction, exacerbating the housing crisis and perpetuating racial disparities in home ownership. Zoning is one of the big villains in Abundance, Ezra Klein and Derek Thompson’s call to reassess the regulations that hinder infrastructure projects.

Some 33 states have passed reforms to allow more density in zones once reserved for single-family homes only, according to the Mercatus Center at George Mason University, which co-hosted a symposium reevaluating the Euclid case last month, with the Pacific Legal Foundation and the Journal of Law, Economics and Policy. Thousands of communities have re-legalized mixed-use development as well, seeking to blend housing with shops and restaurants in walking distance—the kind of neighborhood that Euclid made illegal.

The message is clear: The rules haven’t kept up with the times. And for some, they weren’t such a good idea in the first place.

To be fair, things were pretty messy at the turn of the 20th century, prompting local governments to try to impose order. During the Industrial Revolution, manufacturing facilities were marbled into fast-growing cities like Pittsburgh and Cleveland, leaving smelters and tanneries and brickyards next to worker housing and residential neighborhoods. Immigration and a rural-to-urban migration filled urban neighborhoods with people crowded into tenement houses. Density and mixed-use became associated with dangers to public health.

Beginning in earnest around 1904, municipalities endeavored to tidy up—“a place for everything, and everything in its place,” said Dartmouth professor emeritus and keynote presenter William Fischel, whose 2015 book Zoning Rules! is cited in the early pages of Abundance. (A trivia fact for the next cocktail party: The basic framework of zoning was imported, like the delicatessen, from Germany.) At the same time, Henry Ford’s Model T opened up all kinds of land for different forms of development, Fischel said. The new frontier needed to be organized.

There were also pernicious motivations. As George Mason University professor Olivia Gonzalez pointed out, the Cleveland area in the 1920s was rife with racist policies, like covenants and sundown curfews, but also attempts to control who lived where, through local rules forbidding multifamily housing, small lots, and even alleys.

The fundamental appeal of zoning was that it served multiple aims. Progressives, putting their faith in experts, saw it as a way to make America healthy again, by spreading out and keeping polluting industries away from residential areas; even as that stirred up worries about planned societies and socialism, the US Chamber of Commerce and the commerce secretary and future president Herbert Hoover backed it as good for business.

Euclid wasn’t the first US city to implement zoning: New York City passed the first citywide ordinance in 1916. But the village was an especially enthusiastic early adopter. Its founders included a bunch of surveyors from Connecticut, who had a thing for geometrical arrangements and named the town after the Greek mathematician. Euclid’s response to Ambler’s lawsuit was that the local government was doing what everyone else was doing, guiding growth with practical principles.

Justice Sutherland agreed, characterizing an apartment building in a single-family neighborhood as a sinister “parasite”—a line that planted seeds for the bias and fear related to density that endures to this day. A central theme of NIMBYism, after all, is that new housing is a threat to community well-being, like soot from smokestacks.

With the Supreme Court’s endorsement, zoning was off and running, through the development of single-family suburbs like Levittown and beyond. Around 1970, as Fischel noted, land use regulation got another powerful ally in the form of the growth management movement, with its urban growth boundaries and elaborate environmental protocols aimed at preserving wetlands and open space.

Then zoning came face to face with affordability.

In my 2006 book This Land: The Battle over Sprawl and the Future of America, I predicted that compact, walkable neighborhoods would become more appealing as residents in far-flung, car-dependent subdivisions got tired of paying so much for gasoline. Today the more existential dilemma is that millions of people can’t afford a home or pay the rent. Desirable areas are dominated by single-family homes on large lots, fiercely defended by the current occupants against further development—those parasite apartment buildings—that could accommodate a wider range of incomes. In this view, Euclidian zoning has been weaponized as a tool to lock in the status quo.

In a reveal of how entrenched zoning has been, the regulatory regime has only recently been effectively challenged. Credit goes to YIMBYism and the abundance movement, as well as scholars like Harvard’s Edward Glaeser, who has documented how restrictive land use regulations are stifling urban economies, for finally bringing about what Charles Gardner, senior research fellow at the Mercatus Center, calls “the great land use realignment.”

In addition to the zoning and code reforms already enacted in those 33 states, some 200 more bills have been introduced so far this year, he said. The measures—allowing accessory dwelling units, reducing minimum parking requirements, banning single-family-only zoning, increasing density at transit stations, and streamlining permitting—are getting support in red and blue states alike, including Utah, Texas, Montana, and Indiana.

“It’s a genuine groundswell,” Gardner said, comparing zoning reform efforts to the growth management movement of the 1970s that Fischel referenced. “We might look back on this as a transformative time.”

George Washington University’s Sara Bronin, founder of the National Zoning Atlas, said the first step is to figure out what’s actually in place in the 9,000-plus jurisdictions her team has studied. “We now have the receipts,” she said. “Zoning is here to stay. Our question is how do you make it better.”

But free-market libertarians don’t want to just tweak zoning—they’d rather see Euclid overturned. (Mind you, this was a symposium that handed out keychains with a plastic cut-out likeness of Milton Friedman.) Just like some believe all zoning is racist, these property rights defenders say all zoning can be seen as a regulatory taking in violation of the 5th Amendment (“nor shall private property be taken for public use, without just compensation”).

The standard established in the 1978 case Penn Central Transportation v. City of New York is that regulation of land and property is permissible as long as it is reasonable. But an increasingly conservative Supreme Court has been expanding the definition of what constitutes a taking, in cases like Nollan v. California Coastal CommissionDolan v. City of Tigard, and Sheetz vs El Dorado County. A free-market dream would be a new legal challenge that would force local governments to broadly reimagine how they manage growth and development.

A seismic overturning may not be necessary. Legislative action is clearly prompting a major overhaul of Euclidian zoning, in a nice reflection of democracy’s push and pull. When it comes to land policy, a little fluidity is a virtue—an interplay between foundational principles and adjustments, given how times have changed. So keep the critiques of zoning coming. As a practical matter, a more perfect system awaits. It just might be a better version of everything in its place.

Second Annual Manufactured Housing Benchmark Report Shows Growing Availability of Quality Homes Nationwide

By Kristina McGeehan, Marzo 3, 2026

The Lincoln Institute of Land Policy’s Innovations in Manufactured and Modular Homes Network (I’m HOME) today released the second annual I’m HOME Manufactured Housing Industry Benchmark Report, revealing that manufactured housing production in the United States increased in 2024, furthering the promise that manufactured housing can be a cost-effective, streamlined approach to addressing the country’s severe housing shortage and lack of affordable housing.

“Manufactured homes offer a real opportunity to help meet our country’s housing needs, but to truly deliver, these homes must be durable and energy efficient to ensure safe and affordable housing in the long term,” said Arica Young, director of housing access and affordability at the Lincoln Institute of Land Policy. “This report identifies the places where good work is happening, but also highlights the opportunities the industry has to improve.”

The comprehensive study analyzes 2024 data from the US Census Bureau, US Department of Housing and Urban Development (HUD), US Department of Energy (DOE), and US Environmental Protection Agency (EPA) to assess progress in building safe, affordable housing. The report examines three critical areas: production, certification, and placement of homes; federal programs, regulations, and policies; and financing programs.

Key findings indicate that federal institutions like HUD took substantive steps in 2024 to improve access to durable, energy-efficient, and affordable manufactured housing options, but certain roadblocks continue to prevent all homes from being built to high standards.

“With this analysis, we are working to provide data-driven insights into housing availability and land use patterns that can help advance manufactured housing as a key component of addressing housing affordability and homeownership for people across the country,” said Young.

A webinar on highlights from the I’m HOME Manufactured Housing Industry Benchmark Report is available online. To read the full report, visit here.
