Before zoning, some cities had local ordinances like those in Los Angeles in 1904 limiting "wash houses" (laundries) from operating in a residential area.
These early city ordinances were in some cases motivated by racism and classism.
After the Supreme Court declared racial ordinances unconstitutional in 1917, many localities discovered zoning and began setting down citywide restrictions. In suburban localities, zoning often mandates single-family housing.
Zoning ordinances did not allow African-Americans moving into or using residences that were occupied by majority whites due to the fact that their presence would decrease the value of home. The constitutionality of zoning ordinances was upheld by the

Village of Euclid, Ohio v. Ambler Realty Co.'' in 1926.
According to the ''New York Times'', "
single-family zoning is practically gospel in America," as a vast number of cities zone land extensively for detached single-family homes.
Low-density residential zoning is far more predominating in U.S. cities than in other countries.
The housing shortage in many metropolitan areas, coupled with
racial residential segregation, has led to increased public focus and political debates on zoning laws. Studies indicate that strict zoning regulations constrain the supply of housing and inflate housing prices, increase homelessness, and contribute to inequality, a weaker economy, and racial
housing segregation in the United States.
Zoning laws that prioritize single-family housing have raised concerns regarding housing availability, housing affordability and environmental harms.
In the U.S., support for local zoning against multifamily housing is concentrated among white, affluent homeowners. There are no substantial differences between liberal and conservative homeowners in their opposition to the construction of dense housing in their neighborhoods. However, among the mass public and elected officials, Democrats are more likely to support dense, multi-family housing.
Zoning in the United States is expected to cost hundreds of billions or over a trillion per year in lost economic output.
Origins and history
Many argue that German urban planner
Reinhard Baumister was the first to develop a system of land use separation that could be considered "zoning".
Frankfurt's nineteenth century zoning plans were used as inspiration across America and other countries in Western Europe.

The purported need for formal zoning in America arose at the turn of the twentieth century as cities such as New York, experiencing rapid

Edward M. Bassett, author of the first comprehensive zoning ordinance in the United States, wrote in 1922:
Skyscrapers would be built to unnecessary height, their cornices projecting into the street and shutting out light and air. The lower floors needed artificial light in the daytime. Business centers instead of being rationally spread out were intensively congested. Transit and street facilities were overwhelmed...
Additionally, many of the earliest zoning laws in the United States were influenced by a demand for class,
ethnic, and race-based segregation.
Early zoning ordinances in the United States were more narrow in scope and later became more comprehensive.

passed the first municipal zoning ordinance in the United States, Ordinance 9774, on July 25, 1904.
Though the ordinance did not assign all parts of the city to a zoning map, as with later American ordinances, it did establish three residential districts in which laundries and wash houses were prohibited. The prohibition against laundries had a racial component since many were owned by Chinese residents and citizens.
This ordinance would later be replaced in 1908 with other ordinances that expanded the scope of the residential districts and greatly expanded the scope of prohibited industries.
Existing nuisance laws had already prohibited some industrial land uses in

. A new ordinance adopted on August 3, 1909, established that all land within Los Angeles that was not part of an industrial district would become a residence district.
However, between 1909 and 1915, Los Angeles City Council responded to some requests by business interests to create exceptions to industrial bans within the three residential districts. They did this through the legal device of districts within districts. While some might have been benign, such as motion picture districts, some others were polluting, such as poultry slaughterhouse districts. Despite the expanding list of exceptions, new ordinances in other cities (i.e., 1914 Oakland ordinance) followed the 1908 Los Angeles model through about 1917.
There existed 22 cities with zoning ordinances by 1913.
Race-based zoning ordinances, 19101917
Many American cities passed residential segregation laws based on race between 1910 and 1917.

1916 New York Zoning Resolution

In 1916,

adopted the
first zoning regulations to apply citywide as a reaction to construction of the
Equitable Building (which still stands at 120 Broadway). The building towered over the neighboring residences, completely covering all available land area within the property boundary, blocking windows of neighboring buildings and diminishing the availability of sunshine for the people in the affected area.
Bassett's zoning map established height restrictions for the entire city, expressed as ratios between maximum building height and the width of adjacent streets. Residential zones were the most restrictive, limiting building height to no higher than the width of adjoining streets. The law also regulated land use, preventing factories and warehousing from encroaching on retail districts.

for zoning in the rest of the country, partly because Bassett headed the group of planning lawyers who wrote
The Standard State Zoning Enabling Act that was issued by the U.S. Department of Commerce in 1924 and accepted almost without change by most states. The effect of these zoning regulations on the shape of skyscrapers was illustrated famously by architect and illustrator
Hugh Ferriss.
Standard State Zoning Enabling Act
The Standard State Zoning Enabling Act (SZEA) is a federal planning document first drafted and published through the
United States Commerce Department in 1922, which gave states a model under which they could enact their own zoning enabling laws. The genesis for this act is the initiative of
Herbert Hoover
Herbert Clark Hoover (August 10, 1874 – October 20, 1964) was the 31st president of the United States, serving from 1929 to 1933. A wealthy mining engineer before his presidency, Hoover led the wartime Commission for Relief in Belgium and ...
while he was Secretary of Commerce. Deriving from a general policy to increase home ownership in the United States, Secretary Hoover established the Advisory Committee on Zoning, which was assigned the task of drafting model zoning statutes. This committee was later known as the Advisory Committee on City Planning and Zoning. Among the members of this committee were Edward Bassett,
Alfred Bettman,
Morris Knowles,
Nelson Lewis,
Frederick Law Olmsted Jr., and
Lawrence Veiller.
[Republished by the American Planning Association.]
The Advisory Committee on Zoning appointed a subcommittee under the title of "Laws and Ordinances." This committeewhich included Bassett, Knowles, Lewis, and Veillercomposed a series of drafts for SZEA, with one dated as early as December 15, 1921. A second draft came forth from the subcommittee in January 1922. Several drafts culminated in the first published document in 1924, which was revised and republished in 1926.
Initial reception
During their inception, zoning laws were harshly criticized as an overreach of government power.
Some believed that they were an unjust restriction of private action, while others believed that the power of zoning would be corrupted in the hands of bureaucrats. General P. Lincoln Mitchell went as far as to call zoning laws "an advanced form of communism."
Others supported zoning laws for their uniform and consistent application, and believed that they would be a force of social equality. The constitutionality of zoning laws was highly debated until the ruling of ''Village of Euclid v. Ambler Realty''.
''Village of Euclid v. Ambler Realty Co.''
The constitutionality of zoning ordinances was upheld by the U.S. Supreme Court in ''
Village of Euclid, Ohio v. Ambler Realty Co.'' in 1926. The zoning ordinance of

. Ambler Realty Company filed suit on November 13, 1922, against the Village of Euclid, Ohio, alleging that the local zoning ordinances effectively diminished its property values. The village had zoned an area of land held by Ambler Realty as a residential neighborhood. Ambler argued that it would lose money because if the land could be leased to industrial users it would have netted a great deal more money than as a residential area. Ambler Realty claimed these breaches implied an unconstitutional taking of property and denied equal protection under the law.
The trial court originally ruled in Ambler's favor, holding zoning unconstitutional. Among other reasons, the trial court found that zoning was an illegitimate device to facilitate social and economic segregation. Nonetheless, the U.S. Supreme Court reversed that decision, holding that zoning was a nuisance-preventing device, and as such a proper exercise of the state regulatory police power.

remains an exception within the United States because it never adopted a zoning ordinance. However, strong support existed for zoning in Houston among elements within municipal government and among the city's elites during the 1920s. In 1924,
Mayor Oscar Holcombe, appointed the first funded City Planning Commission. City Council voted in favor of hiring S. Herbert Hare of
Hare and Hare as a planning consultant. Following the passage of a state zoning enabling statute in 1927, Holcombe appointed
Will Hogg to chair a new City Planning Commission.
Will Hogg was a co-founder of the
River Oaks development, the son of a former Texas Governor and an heir to family oil wealth. By 1929, both Hare and Hogg abandoned efforts to push the zoning ordinance to a referendum. In their estimation, there was not enough support for it. Hogg resigned as chair of the City Planning Commission that year.

Mid 20th Century
During the mid-twentieth century, use-based zoning became flatter, and hierarchical provisions that allowed residential uses in industrial areas became less common.
Zoning districts also became larger, increasing the distance between properties zoned for different uses.
21st century
In the early 21st century, several local and state governments across the United States have been relaxing or abolishing specific zoning classes (e.g.
single-family zoning) to address various issues that have arisen as a result of zoning, such as housing affordability crises and racial and socio-economic segregation.
In addition, federal legislation to reform
exclusionary zoning has been proposed by national politicians from both the Republican and Democratic parties since at least the 2010s.
California
In September 2021, the state of California adopted Senate Bill 9 allowing the development of up to four residential units on single-family lots, following a growing push from local governments such as

Implementation

to arise. Most state zoning-enabling laws prohibit local zoning authorities from engaging in any spot zoning because it would undermine the purpose of a zoning scheme.
Zoning laws in different jurisdictions can each specify their rules using their own systems. Although there are some general patterns, such as abbreviations starting with R for residential, C for commercial, and I for industrial, zoning laws do not follow any single consistent system. As one example, residential zones in one city might be coded as R1 for
single-family homes and R5 for
multiple-family homes. In other places, the code R5 could refer to 5 residential housing units per acre or to homes on lots of at least 5,000 square feet.
Legal challenges
There are several limitations to the ability of local governments in asserting police powers to control land use. First, constitutional constraints include freedom of speech (First Amendment), unjust takings of property through the use of zoning that denies land owners the ability to put their land to reasonable, income producing uses (Fifth Amendment), and equal protection (Fourteenth Amendment). There are also federal statutes that sometimes constrain local zoning. These include the Federal Housing Amendments Act of 1988, the Americans with Disabilities Act of 1990, and the Religious Land Use and Institutionalized Persons Act of 2000.
Freedom of speech
Local governments regulate signage on private property through zoning ordinances. Sometimes courts invalidate laws which regulate the content of speech rather than the manners and modes of speech. One court invalidated a local ordinance that prohibited "for sale" and "sold" signs on private property. Another court struck down a law which prohibited signs for adult cabarets.
Takings after 1987
Beginning in 1987, several United States Supreme Court cases ruled against land use regulations as being a
taking requiring just
compensation pursuant to the
Fifth Amendment to the Constitution. ''
First English Evangelical Lutheran Church v. Los Angeles County'' ruled that even a temporary regulatory taking may require compensation. ''
Nollan v. California Coastal Commission'' ruled that

Palazzolo v. Rhode Island'' ruled property rights are not diminished by unconstitutional laws that exist without challenge at the time the complaining property owner acquired title.

Rob Bonta denied this claim. Bonta wrote: "There is no valid basis to claim that the entire town of Woodside is a habitat for mountain lions. Land that is already developed — with, for example a single-family home — is not, by definition, habitat. (...) Our message to local governments is simple: act in good faith, follow the law, and do your part to increase the housing supply."
According to housing advocate Sonja Trauss, this was just one of about 40 cases in which Californian towns attempted to limit, block or discourage housing development to maintain exclusionary single-family zones in violation of Senate Bill 9 (SB9) adopted in September 2021.
Types
Zoning codes have evolved over the years as urban planning theory has changed, legal constraints have fluctuated, and political priorities have shifted. The various approaches to zoning may be divided into four categories: Use-based (known as Euclidean in the US), performance, incentive, and form-based. Euclidean zoning codes with strict use separation are by far the most prevalent type in the United States.
While the use of innovations such as form-based, performance, planned-unit development, and mixed-use zoning are common in the US, they tend to liberate relatively little land area from strict single-use zoning.
Based on a survey of 25 cities, less than 5% of land allows mixed residential and commercial uses.
Amendments to zoning regulations
Amendments to zoning regulations may be subject to judicial review, should such amendments be challenged as
ultra vires

or unconstitutional.
The standard applied to the amendment to determine whether it may survive judicial scrutiny is the same as the review of a zoning ordinance: whether the restriction is arbitrary or whether it bears a reasonable relationship to the exercise of the police power of the state.
If the residents in the targeted neighborhood complain about the amendment, their argument in court does not allow them any vested right to keep the zoned district the same.
[Duggan] However, they do not have to prove the difficult standard that the amendment amounts to a taking.
If the gain to the public for the rezoning is small compared to the hardships that would affect the residents, then the amendment may be granted if it provides relief to the residents.

social engineering. There is criticism of zoning particularly amongst proponents of

political perspectives. The inherent danger of zoning, as a coercive force used against property owners seeking to build integrated housing, has been described in detail in
Richard Rothstein's book ''
The Color of Law'' (2017).
Government zoning was used significantly as an instrument to advance racism through enforced segregation in all regions of the U.S., not only in the South, from the early part of the 20th century up until recent decades.
Circumventions
Generally, existing development in a community is not affected by the new zoning laws because it is "
grandfathered" or ''legally non-conforming'' as a
nonconforming use, meaning the prior development is exempt from compliance. Consequently, zoning may only affect new development in a growing community. In addition, if undeveloped land is zoned to allow development, that land becomes relatively expensive, causing developers to seek land that is not zoned for development with the intention to seek rezoning of that land. Communities generally react by not zoning undeveloped land to allow development until a developer requests rezoning and presents a suitable plan. Development under this practice appears to be piecemeal and uncoordinated. Communities try to influence the timing of development by government expenditures for new streets, sewers, and utilities usually desired for modern developments. Contrary to federal recommendations discouraging it, the development of interstate

In Colorado, local governments are free to choose not to enforce their own zoning and other land regulation laws. This is called selective enforcement. Steamboat Springs, Colorado is an example of a location with illegal buildings and lax enforcement.
Housing affordability
Zoning also has been implicated as a primary driving factor in the rapidly accelerating lack of affordable housing in urban areas. One mechanism for this is zoning by many suburban and
exurban communities for very large minimum residential lot and building sizes in order to preserve home values by limiting the total supply of housing, which thereby excludes poorer people. This shifts the market toward more expensive homes than ordinarily might be built. According to the Manhattan Institute, as much as half of the price paid for housing in some jurisdictions is directly attributable to the hidden costs of restrictive zoning regulation.
For example, the entire town of

(with the exception of the local community college and a religious convent), is zoned for residential use with a minimum lot size of one acre (4,000 m
2) and a limit to only one primary dwelling per lot. All these restrictions were upheld as constitutional by federal and state courts in the early 1970s. The town traditionally attempted to comply with state affordable housing requirements by counting secondary dwellings (that is, apartments over garages and guest houses) as affordable housing, and since 1989 also has allowed residents to build so-called "granny units".

enacted the
Massachusetts Comprehensive Permit Act: Chapter 40B, originally referred to as the anti-snob zoning law. Under this statute, in municipalities with less than 10% affordable housing, a developer of affordable housing may seek waiver of local zoning and other requirements from the local zoning board of appeals, with review available from the state Housing Appeals Committee if the waiver is denied. Similar laws are in place in other parts of the United States (e.g., Rhode Island, Connecticut, and Illinois), although their effectiveness is disputed.
Critics of zoning note that zoning laws are a disincentive to provide housing which results in an increase in housing costs and a decrease in productive economic output. For example, A 2017 study showed that if all states deregulated their zoning laws only halfway to the level of Texas, a state known for low zoning regulations, their GDP would increase by 12 percent due to more productive workers and opportunity. Furthermore, critics note that it impedes the ability of those that wish to provide charitable housing from doing so. For example, in 2022, Gloversville's Free Methodist Church in New York wished to provide 40 beds for the homeless population in -4 degree weather and were inhibited from doing so.
Zoning tax
According to a 2021 study, in San Francisco, the "zoning tax" -which refers to the artificially inflated land prices brought on by tight residential zoning rules- is predicted to be more than $400,000 per home. The study found that the zoning tax in Seattle, New York City, and Los Angeles may reach $200,000. In Chicago, Philadelphia, Portland, and Washington, D.C., it reached $80,000.

Exclusionary
Zoning has long been criticized as a tool of racial and socio-economic exclusion and segregation, primarily through minimum lot-size requirements and land-use segregation.
Early zoning codes often were explicitly racist, or designed to separate social classes.
Exclusionary practices remain common among suburbs wishing to keep out those deemed socioeconomically or ethnically undesirable: for example, representatives of the city of

Since 1910 in Baltimore, numerous U.S. States created racial zoning laws; however such laws were ruled out in 1917 when the U.S. Supreme Court ruled that such laws interfered with the property rights of owners (''
Buchanan v. Warley''). There were repeated attempts by various states, municipalities, and individuals since then to create zoning and housing laws based on race, however, such laws eventually were overturned by the courts. The legality of all discrimination in housing, by public or private entities, was ended by the

(Title VIII of the Civil Rights Act of 1968). Despite such rulings, there is widespread evidence that zoning laws are still used for the purpose of racial segregation. In the wake of the Fair Housing Act, localities increasingly used purportedly non-racial zoning laws to keep non-whites out of white neighborhoods.
Localities prohibited duplexes, small homes, and multi-family buildings, which were more likely to be occupied by racial minorities, recent immigrants, and poor households.
The outcome of segregating different areas of cities and regions by uses or characteristics of uses has resulted in increased racial and economic segregation.
