The local rules that decide what can be built where, and the variances, special permits, rezonings and appeals an owner uses when the rules stand in the way.
Looking for a lawyer rather than a definition? Skip to the state-by-state list of Land Use & Zoning law firms.
Zoning is the local government's division of land into districts with rules on what each parcel may be used for (residential, commercial, industrial, mixed), how large and tall buildings may be, how far they must sit from property lines, how many homes an acre may hold and how much parking is required. The Supreme Court upheld comprehensive zoning as a valid exercise of the police power in Village of Euclid v. Ambler Realty Co., and every state has since authorized its cities and counties to zone through an enabling act. The zoning ordinance and map are adopted by the local legislative body, usually guided by a comprehensive or general plan, and administered by a planning department, a planning commission and a board of zoning appeals or adjustment.
An owner whose plans do not fit the rules has several routes. A variance is permission to depart from a dimensional rule (a setback, height or lot-size requirement) because of a hardship peculiar to the land; use variances are harder to get and barred in some states. A special or conditional use permit allows a use the ordinance lists as permitted only with review and conditions. A rezoning changes the district itself and is a legislative act, which courts review more deferentially, while a variance or permit decision is quasi-judicial and must rest on findings and evidence in the record. A nonconforming use, one that was lawful before the ordinance changed, may generally continue but not expand, and may be lost by abandonment. Appeals usually run from the staff to the board of appeals and then to court on a short deadline, and a neighbor with standing can appeal an approval just as an owner can appeal a denial.
Several federal and state limits sit above the local rules. A regulation that goes too far is a taking requiring compensation (see eminent domain), and a permit condition that demands land or money must be related and roughly proportional to the project's impact (Nollan, Dolan, Koontz, Sheetz). The Fair Housing Act bars zoning that discriminates against protected classes and requires reasonable accommodation for group homes for people with disabilities (see fair housing). The Religious Land Use and Institutionalized Persons Act protects religious assemblies (see RLUIPA), and the Telecommunications Act limits local control over wireless towers. Many states have also passed laws preempting local bans on accessory dwelling units or requiring localities to permit more housing. Private restrictions, such as covenants and easements, operate alongside zoning and can be stricter than it.
Land use work is local: hire a lawyer who appears before the planning commission and board of appeals in that city or county and knows its ordinance, staff and deadlines. Involve them before you buy or sign a lease that depends on a use being allowed, and before the public hearing rather than after a denial, because the record made at the hearing is what a court will review. Appeal deadlines are short and strictly enforced. Neighbors opposing a project should likewise get advice before the hearing, since objections not raised there can be waived.
Worried about the cost? A lawyer can be hired for one part of a case only (limited-scope representation), may be paid from what a claim recovers (contingency fee), or may be free through a pro bono program or legal aid; a court can also waive its own filing fees.
