How to Find Your Zoning and Read the Code

Steps to find your zoning
- Write down the address and the parcel number.The parcel number (also called APN, tax parcel or PIN) is on your property tax bill or on the county assessor’s website.
- Check whether the property is inside a city.If it is outside city limits, zoning may be set by the county. The assessor or planning office can tell you.
- Search for the zoning map.Search for “[city or county] zoning map” or “[city] property search.” Raleigh, for example, offers a Citywide Zoning Map in iMaps, and Miami-Dade offers a Property Search.
- Enter the address and read the district.The map shows a district code and may list overlays or special districts.
- Open the zoning code for that district.Find the use table and the district standards.
- Check the overlays.Historic, flood, transit or design overlays can add rules.
- Confirm with the planning office.Ask in writing, or ask for a zoning verification letter if you need proof for a lease, loan or purchase.
Reading a zoning map and code
| Term | What it means |
|---|---|
| Base district (zone) | The main zoning designation of the property, such as a residential district. |
| Overlay | An extra layer of rules on top of the base district, for example for historic areas, flood zones or design review. |
| Use table | A chart listing which uses are allowed by right, allowed with a permit, or not allowed in each district. |
| By right (permitted use) | Allowed without special approval if you meet the standards. |
| Conditional or special use | Allowed only after a review and permit, often with conditions. |
| Accessory use | A use that supports the main use of the lot, such as a small farm on a house lot. |
| Setback | The minimum distance a structure must keep from a property line. |
| Nonconforming use | An existing use that was legal before the rules changed. |
Questions to ask the planning office
- What is the zoning district and overlay for this parcel?
- Is a community garden, urban farm or farm stand allowed here, by right or with a permit?
- Are there size limits, hours or sales rules?
- Can I keep chickens or bees, and what are the setbacks?
- Do I need a building permit for a shed, greenhouse or hoophouse?
- Is a zoning verification letter available and what does it cost?
- Who is the staff person I should keep in contact with?
If the map or code is unclear
- Zoning maps are updated at intervals, so ask whether the online map is current.
- A few cities, such as Houston, have no conventional zoning but regulate land use through other rules; ask the city what applies.
- Land held by a public agency, a school or a church may follow different rules or review processes.
- A recent rezoning or an amendment may not yet show on the map.
- Property in an HOA is also governed by private rules; see homeowners associations.
Once you know your zone, read our planning and zoning guide, how cities regulate urban farming and what agricultural zoning means. For structures, see building codes.
