Zoning
Zoning is a set of local rules governing how land and buildings may be used. A zoning map identifies districts, and the ordinance describes the uses and building standards for each.
Where the zoning rules come from
A zoning ordinance describes permitted uses and building standards. A zoning map shows where its districts apply. HUD’s glossary describes zoning in terms of permitted and prohibited uses, density, intensity and the location of buildings on lots. The map and ordinance work together: a district name by itself does not describe all the rules for a property.
A comprehensive plan is different from a zoning ordinance. It describes a community’s planning goals; the applicable regulations and approvals determine what is allowed on a particular site. Local terminology and approval procedures vary, so a label used by one community may have a different meaning elsewhere.
Uses and building standards
Rules may distinguish housing, shops, offices and industrial activities. They may also address the size and placement of buildings. A permitted use and a permitted building shape are separate questions: permission for housing does not necessarily allow every height, layout or number of homes.
Changes and exceptions
Local procedures may include rezoning, a variance or conditional-use approval. Rezoning changes the applicable district or rules. A variance concerns an exception to a requirement, while conditional-use review concerns a use subject to specified conditions. Their legal standards depend on the jurisdiction.
HUD’s land-use guide describes how zoning ordinances, subdivision rules and development reviews fit together. These rules provide context for a property’s use; they are separate from the mortgage contract and the state’s foreclosure process.
Questions about zoning
What does zoning mean?
Zoning is a set of local rules governing how land and buildings may be used. A zoning map identifies districts, and the ordinance describes the uses and building standards for each.
How does a zoning map differ from an ordinance?
The map identifies districts; the ordinance states the rules that apply within them.
Does zoning determine the terms of my mortgage?
Zoning governs land use. A mortgage contract and state foreclosure law address separate questions.
