Land use controls are the legal rules that determine what you can build on a piece of property, where you can put it, and how it must fit into the surrounding community. They come from two very different sources: government regulation under the police power, and private agreements between property owners. Together they form a layered framework covering zoning, building safety, environmental protection, government takings, and neighborhood-level covenants. Any single parcel is usually subject to several of these at once.
Zoning: What You Can Build and Where
Zoning is the most visible government control on land use. A local government divides its territory into districts and assigns each one a category of permitted use, usually residential, commercial, industrial, or agricultural. This Euclidean approach gets its name and its legal footing from the Supreme Court’s 1926 decision in Village of Euclid v. Ambler Realty Co., which upheld a city’s authority to separate incompatible uses as a valid exercise of its police power to protect public welfare.1Justia. Village of Euclid v. Ambler Realty Co., 272 U.S. 365 (1926)
Within each zone, the ordinance also sets physical development standards. Height limits control how tall a building can rise. Setbacks establish the minimum distance between a structure and the property lines or street. Density rules cap the number of dwelling units per parcel, which is what determines whether an area develops as single-family homes, townhouses, or apartments.
Behind the zoning map sits a comprehensive plan, sometimes called a master plan. It lays out long-term goals for housing, transportation corridors, commercial growth, parks, and public facilities, and it functions as the policy blueprint that zoning decisions are supposed to follow. Most states require rezonings to be consistent with the adopted plan, and courts reviewing a rezoning often ask whether the change aligns with that plan or amounts to arbitrary spot zoning benefiting one parcel at the community’s expense.
Fair Housing Limits on Zoning
Zoning’s power to separate uses can also be used to exclude people. When a community zones only for large-lot single-family homes and bans apartments, the practical effect can be to price out lower-income residents and disproportionately exclude racial minorities and families with children. The federal Fair Housing Act makes discrimination unlawful on the basis of race, color, religion, sex, familial status, national origin, or disability.2Office of the Law Revision Counsel. 42 USC 3604 – Discrimination in the Sale or Rental of Housing and Other Prohibited Practices Courts and federal agencies have applied the statute to strike down local zoning rules that fall disproportionately on protected groups, even without proof of discriminatory intent. Several states have gone further and now require municipalities to zone for a minimum share of affordable or multifamily housing.
When Zoning Doesn’t Fit Your Property
Zoning maps can’t anticipate every lot and every situation. The law provides three main safety valves.
Variances
A variance is permission to deviate from a specific zoning requirement, such as building closer to a property line than the setback allows. You generally have to show that strict application of the rule would create an unnecessary hardship because of conditions peculiar to your property, like an odd lot shape or a severe slope. The hardship can’t be self-created, and the variance has to be consistent with the spirit of the ordinance. A local board of adjustment holds a public hearing, notifies neighboring owners, and votes. Variances are harder to get than many owners expect, because the standard is genuine hardship, not inconvenience or a preference for something bigger.
Special Use Permits
Some uses are allowed in a zone only with extra approval. A church in a residential district or a drive-through in a commercial zone might be listed as a conditional or special use, meaning the owner has to apply for a permit and meet additional conditions on things like traffic, noise, and compatibility. A special use permit doesn’t waive a rule the way a variance does. It activates a use the ordinance already contemplates under certain conditions.
Nonconforming Uses
When zoning changes, properties that no longer comply aren’t automatically shut down. A corner store legally operating before an area was rezoned residential becomes a nonconforming use and can usually keep going. The protection has real limits. You generally cannot expand a nonconforming use or rebuild it after substantial destruction. Many jurisdictions impose amortization periods that give the owner a set number of years to come into compliance or stop. And if the use is voluntarily abandoned for a specified period, the right to continue it is typically lost for good.
Building Codes and Accessibility
Zoning tells you what you can build and where. Building codes tell you how to build it safely. They set minimum standards for structural integrity, electrical and plumbing systems, fire protection, and energy efficiency. All 50 states have adopted some version of the International Building Code as the foundation for their local building rules, though the specific edition and local amendments vary.
Compliance runs through permits and inspections. You submit plans to the local building department, an examiner reviews them against the code, and once a permit issues, inspectors visit the site at key stages. The building must receive a certificate of occupancy before anyone can legally move in.
Federal accessibility law adds another layer. The Americans with Disabilities Act requires that new commercial construction and public accommodations be designed to be readily accessible to people with disabilities, and renovated portions of existing buildings must be made accessible to the maximum extent feasible, including the path of travel to the altered area. Buildings under three stories or with fewer than 3,000 square feet per floor are generally exempt from the elevator requirement, unless the building is a shopping center, mall, or healthcare office.3Office of the Law Revision Counsel. 42 USC 12183 – New Construction and Alterations in Public Accommodations and Commercial Facilities For existing businesses that haven’t been renovated, the ADA requires removal of architectural barriers only when doing so is “readily achievable,” which depends on the business’s size and financial resources.4ADA.gov. ADA Standards for Accessible Design The current technical rules are the 2010 ADA Standards, which specify dimensions for doorways, ramps, restrooms, parking, and more.
Dividing Land and Developer Exactions
If you want to divide a tract into smaller lots for sale or development, subdivision regulations control the process. You submit a plat map showing lot boundaries, streets, and utilities to the local planning authority, and until that plat is approved and recorded in the county land records, the individual lots cannot legally be transferred to buyers.5American Legal Publishing. Montgomery County Code – Section 3.2 Record Plat Required The developer is often required to install roads, sewer, water, and stormwater drainage, and may have to dedicate land for public roads, sidewalks, or parks.
These demands aren’t unlimited. The Supreme Court has imposed a two-part Fifth Amendment test on development exactions. The condition must have an “essential nexus” to a legitimate government interest, so a city can’t require public beach access as a permit condition unless that access actually relates to the harm the city claims to be preventing.6Justia. Nollan v. California Coastal Commission, 483 U.S. 825 (1987) It must also bear “rough proportionality” to the actual impact of the project, through an individualized determination by the government.7Justia. Dolan v. City of Tigard, 512 U.S. 374 (1994) In 2024, the Court confirmed that these protections apply even when the exaction is imposed through a legislatively adopted fee schedule rather than a case-by-case permit decision.8Supreme Court of the United States. Sheetz v. County of El Dorado, 601 U.S. ___ (2024)
Environmental Controls That Override Local Rules
Federal environmental laws impose their own land use restrictions, and they apply regardless of what local zoning or building codes allow. This is the layer that most often surprises property owners.
Wetlands
Under Section 404 of the Clean Water Act, you need a permit from the U.S. Army Corps of Engineers before discharging dredged or fill material into navigable waters, including wetlands. If your property contains wetlands and you want to grade, fill, or build on them, you have to go through the federal process. Individual permits are reviewed project by project and can be denied if a less damaging alternative exists; general permits cover routine, low-impact activities. Violations carry civil penalties of up to $25,000 per day. Normal farming and ranching activities like plowing and harvesting are exempt.9Office of the Law Revision Counsel. 33 USC 1344 – Permits for Dredged or Fill Material
Endangered Species
The Endangered Species Act makes it unlawful to “take” an endangered species, defined broadly to include harassing, harming, pursuing, wounding, or killing.10Office of the Law Revision Counsel. 16 USC 1532 – Definitions Federal regulations read “harm” to include significant habitat modification that actually kills or injures listed wildlife, so development that destroys habitat on your property can trigger federal enforcement.11U.S. Fish & Wildlife Service. Section 9 Prohibited Acts A landowner who needs to proceed can apply for an incidental take permit, which requires a habitat conservation plan that minimizes and mitigates the harm.
Contaminated Property
If you’re buying property, the Comprehensive Environmental Response, Compensation, and Liability Act creates a strong reason to investigate before closing. CERCLA can hold a current owner liable for cleanup costs even if the contamination predates ownership. The main defense is proving that you conducted “all appropriate inquiries” into prior uses before acquiring the property.12Office of the Law Revision Counsel. 42 USC 9601 – Definitions In practice, that means commissioning a Phase I Environmental Site Assessment from a qualified environmental professional, covering historical records, aerial photographs, government environmental databases, and a physical inspection. As of February 2024, the assessment must follow the ASTM E1527-21 standard to qualify for CERCLA liability protection, and it has a shelf life of 180 days before acquisition, extendable to one year if key components are updated.
When the Government Takes or Over-Regulates Your Land
The government can reshape land use by taking property outright or by regulating it so heavily that the owner loses most of its value. Both scenarios trigger the Fifth Amendment’s rule that private property shall not “be taken for public use, without just compensation.”13Congress.gov. Amdt5.10.1 Overview of Takings Clause
Eminent Domain
Eminent domain is the power to acquire private property for a public purpose over an unwilling owner’s objection. Traditional uses include highways, schools, and utility lines. The Supreme Court expanded “public use” in 2005 in Kelo v. City of New London, holding that economic development projects can qualify even when the property is transferred to a private party.14Justia. Kelo v. City of New London, 545 U.S. 469 (2005) The decision was controversial, and many states have since enacted their own restrictions on using eminent domain for private economic development.
The process starts with an appraisal that sets fair market value and the government’s offer. If the owner and the government can’t agree, the matter proceeds to a condemnation action in court. Compensation is measured by the property’s value at its highest and best use at the time of the taking, not just its current use. A vacant lot zoned commercial, for example, is valued on its commercial potential even if nothing has been built on it.
Regulatory Takings
Sometimes the government doesn’t physically seize property but regulates it so aggressively that the owner is effectively deprived of its value. The owner can then file an inverse condemnation claim, arguing that the regulation is a taking that requires compensation. A regulation that eliminates all economically beneficial use of land is a per se taking. Short of that, courts apply a balancing test that weighs the economic impact of the regulation, the extent to which it interferes with the owner’s reasonable investment-backed expectations, and the character of the government action.15Legal Information Institute. Regulatory Takings and the Penn Central Framework There’s no bright-line formula. Most regulations survive because they leave the owner with some economic use, but the doctrine sets an outer limit on how far zoning, environmental rules, and historic preservation controls can go before the government has to pay.
Private Controls: CC&Rs and HOAs
Not every land use restriction comes from the government. Covenants, conditions, and restrictions are contractual rules that property owners agree to when they buy into a development, and a homeowners association usually administers them. Because CC&Rs are recorded in the county land records and run with the land, they bind every future owner, not just the one who signed on originally.
These rules often go well beyond what zoning requires. Common examples include mandating specific architectural styles, limiting exterior paint colors, requiring minimum landscaping, and prohibiting commercial vehicles in driveways. The HOA board enforces compliance and can impose fines or place liens on a property for violations. Homeowners fund the association through regular dues that pay for maintenance of common areas and enforcement. Disputes are civil matters resolved through contract law, not government prosecution, so enforcement depends on the HOA’s willingness to act and ultimately on litigation between private parties.
Before buying into an HOA-governed community, read the CC&Rs carefully. They can reach everything from the breed of dog you own to whether you can install solar panels, and they’re far harder to change than local zoning. Amendments typically require a supermajority vote of all homeowners.
