Less well known is that the ancient case that launched the United States’ 38,000 local zoning codes, Village of Euclid v. Ambler Realty Co., 272 U.S. 365 (1926), turns 100 years old on November 22 of this year. Famously argued twice, on January 27 and October 12, the case is perpetually on the list of Top 5 property rights cases to know. I decided this anniversary was as good a time as any to step back and consider the legacy of Euclid’s century of zoning. Oh, and the fact that the case lends its name to this Substack… there’s that, too.

This post is the backgrounder, the basics any sensible person should know regarding the case itself. There are entire books on Euclid, and if you want one of those, you couldn’t do better than Prof. Michael Allan Wolfe’s The Zoning of America.

This won’t be that exhaustive, but it will level the field so all can tag along. For the property geeks out there: I plan to touch on the more contentious parts of Euclid in future posts. Here, I simply want to introduce the structure of the case and give some texture to why the case is both still important in some ways while being superseded in others. Of course, feel free to comment on things I don’t discuss here and maybe I’ll make a post out of it. So here we go…

By the time the U.S. Supreme Court took up Euclid in 1926, larger cities in the United States had already begun to experiment with zoning. In the usual narrative, it’s said that New York City passed the first zoning code in 1916, but it’s fair to say that zoning fever was in the air and lots of cities were trying it out.

Zoning got a boost in the early 1920s when the Standard State Zoning Enabling Act (SZEA) was distributed by the U.S. Commerce Department’s Advisory Committee on City Planning and Zoning. The committee included luminaries from private and public sectors including the landscape architect Frederick Law Olmsted and two well-known lawyers, Edward M. Bassett of New York and Alfred Bettman of Cincinnati. (See the SZEA, and a great history of it, at this American Planning Association link).

The SZEA was a model statute for states to adopt—it was not federal law—that would, in turn, give local governments the authority to zone while also establishing parameters intended to make sure certain standards, such as due process, were followed. By 1926, when Euclid was heard in the Court, some 43 states had already enacted enabling statutes based upon the SZEA and over 500 local governments had adopted zoning ordinances.

In 1922, the Village of Euclid, a Cleveland, Ohio suburb, was one of those local governments that established a zoning code in large part based on the SZEA. The village’s 1922 ordinance clocked in at a modest 13 pages (see the original ordinance and map here) and included a land use map establishing zoning districts. You can’t look back at those 13 pages and wonder if folks had any idea of the thousand-page zoning codes that were to come!

This map above super-imposes the village’s original 1922 land use map litigated in the case onto a contemporary zoom-able map. Click on the link to zoom in.

In any case, the Village of Euclid’s districts were an example of cumulative zoning. This is one of the things that makes the case somewhat of an anachronism because few local governments use this form of zoning today. Instead, most codes today regulate uses with a use table that creates an intricate list of permitted, accessory, and conditional uses. (See, e.g., Chicago’s residential use table here).

But Euclid’s code divided the city into one of six use districts labeled U-1 to U-6, as well as three height districts and four area districts (today we’d say “bulk” districts). In each district, the uses were cumulative, which meant that each class of districts going up in number permitted all of the uses of the lower districts. Here is a summary from the case of what was permitted in each of the village’s use districts:

Id. at 380–81. What made the village’s code cumulative was that anything in a higher number district also permitted any use in a lower number district, but not vice versa. For instance, in a U-6 district, any use in U-1 through U-5 was also permitted. The reason cumulative zoning isn’t used much is obvious: it doesn’t eliminate some of the basic problems zoning tried to fix, such as a single-family home next to an industrial facility, which would be possible in a U-6 district. What made—and continues to make—Euclid so important, however, was the village’s U-1 district, which essentially restricted property to single-family homes. Most commentators today would say it was really that U-1 district that was being litigated here because of its dramatic reduction in the types of uses permitted. And yes, this is the same single-family districts that today’s housing advocates are struggling so hard to get rid of, such as with California’s SB9 legislation.

It is hard to overestimate how dramatically this use district regulation altered the common law’s approach to uses. In essence, zoning—and especially the U-1—inverted the way American law thought about property rights. At common law, uses were generally permitted unless they were in violation of some background principle of the common law, such as nuisance, or otherwise forbidden by regulation, which really didn’t exist until the mid-nineteenth century. As one Minnesota jurist stated it, the common law establishes the “fundamental principle that one may use and enjoy his property as best suits his convenience, so long as no unnecessary injury is done to his neighbor.” State v. Houghton, 144 Minn. 1, 23, 176 N.W. 159, 164 (1920) (dissent). Today, courts recognize this inversion of property rights as zoning’s “derogation of the common law.” See, e.g., Chanhassen Estates Residents Ass’n v. City of Chanhassen, 342 N.W.2d 335, 340 (Minn. 1984). That background still informs the way courts read zoning codes and think about whether a regulation might “go too far” and be a regulatory taking.

The challenger to the Euclid ordinance was Ambler Realty Company, which owned land near two railroads that it intended to develop for industrial uses. However, land owned by Ambler Realty was placed into strips of use districts by the zoning map that included the U-2, U-3, U-4 and U-6 districts. This hampered Ambler Realty’s plans for industrial uses that it believed had a market value of about $10,000 per acre without zoning but only $2,500 per acre with the zoning. Id. at 384. While this diminution in value would be a factor in today’s regulatory takings analysis under the Penn Central regulatory takings test, the Court in Euclid mentions it, but then largely ignores this issue as a legal matter.

Why? The case was being litigated in a time when regulatory takings was not well developed.

The case that began the modern regulatory takings analysis, Pennsylvania Coal Co. v. Mahon, 260 U.S. 393 (1922), was just a few years old and its invocation that some regulation might “go too far” and thus require compensation as a taking was still uncertain. Risking it all on a takings claim would have been considered a risky challenge. There was a better claim at the time.

But it is interesting to think about how Ambler Realty had any skin in the game. As noted previously, it was generally understood that Euclid was about the viability of the single-family district. But Ambler Realty had no land zoned in the U-1 district, which begs the question of how this case is considered a challenge to single family zoning. The answer is that Ambler Realty’s challenge to the Euclid zoning ordinance wasn’t based on how Ambler Realty’s land was zoned; that would have been an as-applied challenge. Instead, Ambler Realty brought a facial challenge to Euclid’s authority to zone at all. For those who try to read Euclid, this can be hard to see. The way the Court wrote the decision, it reads much more like they are concerned with Ambler Realty’s property itself. But the most important issue on the table in Euclid is whether single family districts are constitutional, and that can only be at issue because this is a facial challenge to the authority to zone at all, not the fate of zoning’s effects on Ambler Realty’s property specifically.

That then brings us to the most surprising part of the case for many readers: the legal claim Ambler Realty brings is in substantive due process under the 14^th Amendment. Today, substantive due process claims almost never prevail in zoning matters. Instead, we have become accustomed to takings, equal protection, and procedural due process being the most important constitutional issues at play in typical zoning cases. But at the time, the Lochner-era Court was using substantive due process to invalidate a wide variety of local government regulations, which is chronicled empirically in an excellent 1927 Harvard Law Review article. As a result, it made perfect sense at the time to bring this case under substantive due process, but the Court bucked its broader trend. Instead of striking down zoning under substantive due process, the Court instead ruled that zoning laws and property regulations are constitutional under the Fourteenth Amendment unless they are deemed “clearly arbitrary and unreasonable” and have “no substantial relation to the public health, safety, morals, or general welfare.” Id. at 395. This highly deferential standard largely killed any substantive due process claim against zoning then and, to this day, such claims remain hard to win.

One last background note: is important to understand that Euclid was decided against a backdrop of ever-increasing private land use regulation through the growth of restrictive covenants. None other than Frederick Law Olmsted, arguably the leading landscape architect of the time, used restrictive covenants to achieve a suburban look—and segregated communities—that many today probably associate with zoning. But such single-family communities were popular at the time (at least with those that got to live in them), and the idea that they could be created by private regulation implicitly forced the hand of public regulation in ways that will be unpack in further posts.

That’s a lot, but it should be enough about Euclid to allow us all to see the big picture. And the central vision of that big picture is this: before the ancient case of Euclid, there were several hundred local governments with zoning. Today, some 38,000 local governments exercise zoning authority. This case, tied to the legal arguments of its time more than our own, nonetheless launched the zoning and the land use planning we live with today. The century since has been nothing less than an a property rights odyssey in epic proportions, replete with heroes and villains (depending on whom is telling the tale), monumental labors, and Homeric drama. Alright, maybe I’m exaggerating a little, but still, it’s a good story.

And so, subscribe now (for free!) and get all the posts in the Euclid@100 series where I’ll try to tell some of Euclid’s legacy, give it some context, and build a conversation about zoning’s future along the way.

The problems with local control of land use have been obvious since at least the post-World War II boom. But when trying to think up solutions to those problems in the Sixties and Seventies, the primary turn was to state and regional governments. There are a couple of famous examples.

Oregon started its statewide planning system, which continues to this day, that imposes planning requirements on local governments across the state.

Other regional bodies took control of the planning and permitting function for an entire region and often to address environmental problems.. The Tahoe Regional Planning Agency was formed to address problems with degradation of water quality in the Lake Tahoe basin. The Columbia River Gorge Commission was similarly formed to control development along the Columbia River as it forms the border between Oregon and Washington. Transportation was another reason why planning turned to regionalism. Ada County, the region around Boise, Idaho, created a county-wide highway district that controlled not only the roads in the county but within city limits as well. (That was an unusual arrangement; Boise remains the only large American city that doesn’t control its roads.) Moreover, this was also the era of the rise of the special district, which could be used to fund infrastructure—transportation was common, but also drainage (in the east), irrigation (in the west), mosquito abatement, libraries, you name it—across the lines of municipal incorporation.

The Tahoe Regional Planning Agency is a regional planning authority that permits development in the Lake Tahoe basin.

Regional planning was also imposed, in some instances, from the federal government. For instance, regional air districts became an important part of Clean Air Act Planning. And regional metropolitan planning organizations (MPOs) became part of federal highway spending, conducting their own shadow planning exercises related to transit but based on local land use plans.

The rise of this regionalism was once called the “quiet revolution” in land use planning. But half a century on, regionalism—much less state planning—appears to have lost its luster. What has taken its place? Preemption.

To hear reformers today tell it, and especially those in the YIMBY movement, there is nothing preemption can’t solve. The problem with localism is not the form of government, as regionalism implicitly argued; the problem is government itself. It is remarkable how complete this turn has been when you look at the response to housing. To the extent localism’s parochialism has been structurally altered, the approach of housing policy has been almost entirely to preempt local control. This has been true in both red and blue states. There are too many examples to cite, but a few will do: California’s preemption of regulation on accessory dwelling units; California’s preemption of single-family zoning; Florida’s significant preemption of local land use planning in the 2026 session; and the so-called “Montana Miracle” housing policy that was, essentially, local preemption. The list could go on.

The turn to preemption likely expresses a national mood of exhaustion with administrative processes that are often seen as too cumbersome and time consuming. On the right, this lives in the libertarian-oriented think tanks that are more anti-government than late-twentieth century conservatives’ small-government mandates. On the left, it lives in the abundance movement and Ezra Klein’s outrage at the process and money it takes to install a toilet in a San Francisco park.

But we are well into trying on this preemption approach to housing policy. There are some modest successes, but it’s not like these policies have been the slam dunks to affordability everyone expected. Is it time to reevaluate the playbook? Is it time to try on a different solution? Is it time to give state- or regional planning a try at housing?

Before heads explode, let me try on a few ideas, which are admittedly half-baked but at least illustrate how old and new ideas might mix. Take, for instance, the problem of “missing middle” housing. So much hope in the early 2020s hung on the idea that we could tear down single-family homes and replace them with duplexes and triplexes. Single-family districts were abolished all over the country…and then (almost) nothing happened. The post-mortem is still under way, but the problem appears to be of mixture of expense (e.g., demolition, duplicating expensive parts of the house like the kitchen) and, as this era’s answer goes, that there is still too much regulation. What if there was some kind of regional or statewide agency, say, to assist with these kinds of issues? Figure out if there really was too much regulation still, and say, create a standardized approach to the problem? Or, as the costs of missing middle are largely ones of scale that the market has not found a way to figure out, maybe that is when government could step in to assist with infrastructure and spur the market? What kind of assist with missing middle would developers need? If lenders are unwilling to lend to a riskier product type like missing middle, perhaps there is a government-backed lender that would? Maybe…a state-back lender that has a small equity stake that replenishes the funding for the next project?

Here is another idea. The current approach to preemption on housing policy is to give some mandate—eliminate single-family districts—but that does not take into account the complexity of everything else that is bound up in that. That is largely what killed the BUILD Act in Illinois. Or, at least, as of now. But what if there was a state agency that set housing targets and gave local governments a list of policies they could utilize to hit those targets. The local governments implement the policies that make sense locally and achieve the state targets. If they don’t, there is some sort of hammer that comes down—say the builder’ remedy—that makes it easy for developers to build housing in the jurisdiction. In this case, there is at least some option for local governments to try to fix the problem in a locally-pertinent manner. There is some effort at crafting policy, not just preemption.

Is this all too pie-in-the-sky? I am guessing most reading will say yes. Because we are too tired of NIMBY (not in my back yard) politics, the slow-walking by local government officials, and so on. Maybe it is right to question local government’s ability to reform itself.

But is preemption the obvious and only answer? I don’t think so. And it occurs to me that we could lean more heavily into state or regional planning efforts. It wouldn’t have to look like the old approaches. It could be lean—hey, it could even be abundant—and show off what government with accountability looks like. Maybe.

Even if I am wrong, the fact that there is so little discussion of state or regional planning in the current housing crisis just shows how much planning has changed. Whatever comes next, my bet is there will need to be models of effective and accountable government to achieve results in the built environment that meet people’s needs and that preemption alone won’t get us there.

The village purchased a 2.6-acre property that was the former church site with the goal of developing moderately-priced single family homes. That, in itself, is a win where market forces often take developers to the top of the market. Instead of the usual 3,000+ sf units that dominatee the Chicago suburbs these days, the development will feature three different single-family home styles ranging in size from almost 1,300 square feet to over 2,000 square feet with home prices will range from $466,000 to $508,000. The project will also be the first single-family homes in the village in over 20 years.

Building affordable missing-middle homes would be a story unto itself. But there’s more. The new units will be auctioned off—similar to the NFL Draft, in the village’s telling—to residents first. Here is a truncated version of how the city intends to run the raffle:

Although the village isn’t positioning it this way, this also seems an intriguing way to think about anti-gentrification efforts. The village could have re-sold the property to a developer and maximized land value by allowing larger homes, but they didn’t. The village also could have turned the lot into subsidized affordable or inclusionary housing, but they didn’t. Instead, they opted to produce what most people want, which is a market-rate home that fits an average income. Offering it first to residents gives them a chance to stay in a place they call home.

Images of the lot plans are below:

The headline-grabbing detail about SB 1352 is that it requires cities to allow subdivision lots as small as 1,500 square feet. That is really small: a typical urban lot in an American big city is usually something like 25’ x 100’, or 2,500 sf. But like so many of these bills, the devil is in the details. Here are some of the problems with this legislation that will likely mean it has little impact:

The legislation is limited to cities with populations over 10,000 people. That is only about 20 of Idaho’s 200 cities, and almost all of those are in the Treasure Valley around Boise. In other words, the legislation doesn’t apply in most of the state.

The legislation’s bulk and height calculations are real head-scratchers. The bill allows front setbacks of 15’ and side yard setbacks of 5’. The local governments can’t require lots to be wider than 30’ or deeper than 70’. On its face, that kind of makes sense, but then you do the math. A 30’ x 50’ lot with a 15’ foot front setback and 5’ side yard setbacks starts to look kind of small. Oddly, there is no regulation of rear yard setbacks, and those are often 15’ - 20’ in Boise. Altogether, that means a lot that starts out 30’ x 50’ would have a building envelope of 20’ x 20’, or just 400 sf. There is also no requirement in the legislation as to building height, which means local governments could limit these structures to just single-family structures. I find it hard to imagine that any developer is going to build a traditional single-family dwelling of just 400 sf. Each small unit still requires the most expensive parts of a house—the kitchen and bathrooms—without the value created by the other less-expensive-to-build living space. It’s hard to see how this pencils out for a developer. The only potential product I see going on such a lot is something like a single-wide or double-wide pre-fabricated modular home. However, the flexibility in zoning permitted by this legislation will allow cities that don’t want that kind of development to easily avoid it.

Ironically, Boise has some of the most economically-diverse neighborhoods I have ever seen. I lived there for 12 years in the city’s North End neighborhood. That neighborhood was originally developed slowly and built out in 25’ x 100’ lots. A new home could be on anything from one lot (25’ x 100’) to three lots (75’ x 100’). The result was an economically integrated neighborhood created by varied lot sizes that often differed on the same block. I have never seen anything quite like it anywhere else.

The North End of Boise’s varied lot size creates economically-integrated subdivisions based on land value.

This varied lot structure has long seemed to me a way of breaking up monotony in suburban settings and also allowing for a wider range of market-rate units in the same community. The question has always been how to create a regulation that models what was built in the North End through piecemeal lot sales. While I commend the efforts of SB 1352, I don’t think it will result in significant new production and, moreover, could lead to significant tracts of lower-income market-rate housing that is easy to zone out of resources like access to good schools. I wish Idaho, and other reform-minded jurisdictions, would consider integrated subdivision lot sizes like in the North End a method of building integrated market-rate communities.

I’m re-posting here an opinion piece I wrote for Crain’s Chicago Business about housing legislation currently under consideration in Illinois. (Link here.)

Gov. JB Pritzker’s proposed BUILD Act legislation is the state’s newest effort to address housing affordability. There are only two problems with the legislation as written: Data from other states tells us it is unlikely to produce much housing. Also, it will make a lot of people mad. There must be a better way.

The BUILD Act boils down to several policy mandates that pre-empt the historic local control of zoning. The big proposals would eliminate single-family zoning and allow multiunit development depending on the size of the lot. For instance, the legislation would allow the owner of a typical suburban lot — 5,000 square feet — to build four dwelling units. The legislation’s other big proposal would also require that accessory dwelling units (ADUs) be permitted in any zoning district. The legislation also eliminates parking requirements for certain projects and allows residential buildings with single stairways.

All of these ideas are recycled from other states — both liberal and conservative — trying to address housing affordability. By looking at those states, we know this legislation won’t produce new housing. For instance, a 2025 analysis by the pro-housing group YIMBY Law found that California’s housing legislation, which ended single-family zoning and mandated ADUs like the BUILD Act seeks to do, had “little to no impact on the state’s housing supply.” A study by U.C. Berkeley’s Terner Center found that only a couple hundred new homes were produced in California by almost identical measures to those in the BUILD Act.

There are many reasons why these reforms haven’t worked that are applicable to Illinois. First, the complexity of local land use regulation means that local governments have many ways to resist mandates they don’t want to implement. The BUILD Act does not have the details necessary right now to prevent that.

Second, most housing built since 1980 is burdened by CC&Rs, which are private regulations that still limit lots to single-family homes even if the zoning changed. Given the distribution of CC&Rs in the Chicago region, the most likely effect of the BUILD Act would be to direct development into areas with high amenities but low land value. That tends to be found in urban lower middle class communities of color that would see gentrification while whiter suburbs with CC&Rs would be mostly unaffected by the BUILD Act.

Third, the BUILD Act does not address the primary method of regulating suburban growth, which is through contractual annexation agreements and development agreements that negotiate land use entitlements and fees no matter what the zoning is.

Finally, experience in other states indicates there are few developers interested in tearing down single-family homes and building duplexes other than in high-end markets. Policymakers need to figure out why, but so far this is an opportunity the market doesn’t want, much less at any significant scale.

The better way is a policy menu approach to mandating housing reform. This would give local governments a list of housing policy options to choose from and mandate that the local government choose a couple to implement given local conditions. Here are some examples of what that might look like. Much of the new housing production since the 2008 recession has occurred through repurposing retail commercial space — arterial street retail and mall sites — that has been hit hard by changes in retail into rental housing.

A repurposing of suburban office space or industrial sites to housing uses is equally viable in many Chicago communities as remote work trends make many of those office uses untenable. Local governments should get credit for pursuing strategies like these that encourage long-term planning to reinvent the community’s underperforming legal land uses.

Similarly, while reducing parking is a good idea usually — parking advocate Donald Shoup noted that “free parking” is really built into development costs and passed on to the consumer — it makes most sense near transit. A menu method could incentivize cities to pursue parking reductions close to existing transit nodes that encourage the creation of new car-less transit options in the suburbs. Subdivision codes are also a potential for reform.

Reducing minimum lot sizes reduces the burden of land value and makes homes more affordable. Local governments should be encouraged to take this step. Zoning in manufactured housing and mobile homes as alternative rent structures for low-income individuals is another strategy that could work, especially in more exurban and rural communities.

Cities that have naturally occurring affordable housing, or NOAHs, could work with landlords to ensure that units continue to be offered at an affordable rate. Rezoning excess land at institutional uses like schools and churches, sometimes call the “Yes in God’s Back Yard” or YIGBY movement, to allow housing could be another way to unlock housing at community scale.

Local zoning codes could also be reformed to alter the definition of “family,” which often limits the number of un-related individuals that can live together in a unit. Density bonuses could be offered near transit, historic preservation ordinances could be altered to allow more units in older neighborhoods and tiny homes on wheels — a different land use classification than ADUs — could be zoned in.

By using a menu approach, Pritzker could present a novel path forward in housing policy. On the one hand, the state would demand action on housing affordability. On the other hand, the state would allow local governments to choose housing policies most likely to work in their communities. Of course, there would need to results and remedies for inaction. Yearly evaluations and grades for implementation are a way to do this, perhaps similar to how school performance is measured. More heavy-handed strategies would be appropriate for local governments that refused to take action.

More housing needs to be built in every part of the state, but what makes sense depends on context. Making local governments a partner in the housing solution and pursuing broader housing remedies is the most likely path to affordable, attractive and diverse communities for Illinois.

Stephen R. Miller is a law professor at Northern Illinois University College of Law and a former editor of the ABA Journal of Affordable Housing & Community Development Law.

Another piece of legislation would limit maximum parking on dwelling units to .5 parking spaces per multifamily housing unit and 1 parking space per single-family home.

Not surprisingly, local governments are looking for a seat at the table.

• Many California jurisdictions rely on housing “overlay” zones to meet rezoning requirements under State Housing Element Law. In New Commune DTLA LLC v. City of Redondo Beach, the Second District Court of Appeal held that “[a]n overlay cannot be used to satisfy the minimum density and residential use requirements … where the base zoning expressly permits development that does not include housing.”

• This decision significantly reinterprets State Housing Element Law and invalidates the City of Redondo Beach’s Housing Element, despite it having been certified by the state’s Department of Housing and Community Development.

• The new ruling may expose numerous jurisdictions to new Builder’s Remedy applications, though it is unclear whether additional litigation is required to affirmatively invalidate other housing elements.

• The decision also creates uncertainty for non-Builder’s Remedy applicants who seek to utilize housing overlay zoning to develop other residential, nonresidential or mixed-use projects.

Here is the blurb:

Zoning is the tool that everyone loves to hate. It may also be the most important and least understood process affecting how US communities shape the lives of their residents. While almost every community comprehensive plan calls for more affordable, equitable, and sustainable development, zoning is often blamed for preventing that from happening. As US communities face an unprecedented housing affordability crisis, a long history of excluding the poor and disadvantaged from key opportunities, and a continuing climate disaster, zoning needs to change – a lot.

In An Even Better Way to Zone, planning expert Donald L. Elliott explains how outdated assumptions about development and unnecessary barriers in our current zoning regulations have contributed to development patterns that are not sustainable, affordable, or equitable to historically disadvantaged populations. It identifies what types of changes to zoning rules, procedures, and maps could improve outcomes in each of those areas. Importantly, it also helps the reader think through what to do when zoning changes that would improve outcomes for one of those challenges would undermine success in the others.

An Even Better Way to Zone also reorients the zoning discussion towards redevelopment and reuse rather than implicitly focusing on raw land development, because already developed areas represent the vast majority of the built environment where meaningful changes will need to be made. Instead of giving lip service to the importance of infill and reuse, zoning needs to actively remove the barriers that prevent innovative, equitable, and sustainable redevelopment.

With engaging, easy-to-understand prose, Elliott briefly explains the challenges of today’s zoning and then breaks down how this key legal tool can be used to reinvent our communities as places where housing is more affordable, everyone is treated fairly, and we do far less damage to the environment. From fixing zoning rules and incentives to fixing the procedures used to draft, implement, and change zoning, Elliott provides practical, sage advice on adapting zoning to address today’s most critical issues.

The title is in reference to one of Don’s earlier books, which is also worth reading and called A Better Way to Zone.
