How to Check the Zoning on Arizona Land

Step one: city or county?

Land inside an incorporated city or town is zoned by that city or town. Land outside any city or town limits, which is most rural acreage in Arizona, is zoned by the county. Each has its own zoning ordinance, its own district names and its own planning staff.

Your mailing address does not decide this. Rural parcels often carry the postal name of the nearest town even when they are miles outside its limits. Tonopah, for example, is a mailing address for a large stretch of unincorporated desert, so every zoning question there goes to Maricopa County. The reverse happens too: a parcel with a Buckeye or Kingman address may be inside city limits under city zoning, or outside under county zoning. Two parcels close to each other can be under different rules.

To confirm jurisdiction, look at the city-limits or annexation layer on the county GIS map, or call the county planning department with the APN and ask.

Step two: find the zoning designation

Counties publish zoning on their GIS maps, but how they do it varies. A few examples:

• Maricopa County: the county's PlanNet map shows county zoning, annexations and floodplain delineations for unincorporated parcels. The assessor's parcel data only carries a city zoning value for parcels inside incorporated areas, so do not read a blank there as "no zoning." Use PlanNet or ask the county.
• Pima County: the county's GIS reports zoning on the parcel layer itself, so the parcel record shows the designation directly. Pima also offers a formal zoning verification letter through its development services department.
• Yavapai County: the county GIS has a zoning map layer and reports zoning for parcels.
• Other counties: start with the county GIS viewer in our Arizona county GIS map directory. If zoning is not shown, the planning department can tell you.

Our parcel research tool shows zoning where the county publishes it on the parcel layer, along with flood and water information. Treat any map value as a lead to confirm, not a final answer.

A procedure that works in any county

1. Get the APN (see how to look up a parcel by APN).
2. Open the county GIS map and turn on the city-limits and zoning layers, if offered.
3. Write down the zoning code exactly as shown, including any suffix or overlay.
4. Find that code in the jurisdiction's zoning ordinance and read the permitted uses, minimum lot size, setbacks and any special rules for manufactured homes or accessory buildings.
5. Call or email the planning department to confirm. For a purchase or a sale, ask whether they issue a written zoning verification.

What zoning codes mean

Zoning codes are local shorthand, and the same letters can mean different things in different counties. Rural counties commonly have districts for general rural use, rural residential use on larger lots, single-family residential, commercial and industrial. The district usually sets:

• Which uses are allowed outright, which need a use permit, and which are prohibited.
• Minimum lot size and lot width, which matters if you want to split the land.
• Setbacks from property lines and height limits.
• Whether manufactured homes, RVs, livestock or agricultural buildings are allowed.

Do not rely on a summary, including this one, for the details. Read the ordinance itself. County ordinances and planning offices:

Each county page on our site, such as Yavapai County land information, links that county's planning office.

Plans are not zoning, but they matter

Counties also adopt comprehensive plans and area plans that guide future rezoning. Maricopa County's comprehensive plan, Framework 2040, was approved in May 2026, with area plans for places such as Tonopah/Arlington and Rainbow Valley. A plan does not change your zoning by itself, but it signals what the county is likely to approve if you or a neighbor apply to rezone. Yavapai's Planning Unit, for instance, describes its job as processing rezoning requests, use permits, variances and plan amendments.

What zoning does not cover

Deed restrictions and CC&Rs are separate from zoning. A subdivision's recorded restrictions can limit what you build, whether a manufactured home is allowed, or how the lot is used, regardless of what county zoning permits. The county will not enforce them for you or tell you about them; they are found in the county recorder's records and in a title report. Apache County's Concho Community Plan, for example, notes several deed-restricted subdivisions marketed to out-of-state buyers in the 1970s; recorded restrictions like those can still apply to lots sold today.

Zoning also does not tell you whether the land has legal access, water, power, or a buildable site outside a floodplain. Those are separate checks covered in our guide on whether Arizona land is buildable.

Call the planning department

For anything that affects a decision, call. Give the APN, describe what you want to do (build a home, place a manufactured home, split the parcel, keep animals), and ask what zoning applies and what permits you would need. Maricopa County, for example, takes questions through an online inquiry system and by phone at 602-506-3301. Planners answer these questions every day, and their answer outranks any map or website.
