In a county, Arizona lets a parcel be divided into five or fewer lots through staff review instead of a subdivision plat, as long as the county has adopted the process and every lot meets minimum zoning size. The state law is A.R.S. 11-831. Inside a city, the city's own code governs. Split into six or more and you are a subdivider, with a plat, an engineering review and a water-supply test.
This page walks through the county process, the traps, and the number most owners want: do the pieces sell for more than the whole. In our sales, usually yes per acre, though part of the gap is location, not size.
What the county checks
Under A.R.S. 11-831, a county can approve divisions of five or fewer lots, parcels or fractional interests, any of which is ten acres or smaller, without a public hearing. If the county does not finish reviewing within 30 days, the division is considered approved. It may not deny one that meets the rules. The rules are five items:
- Each lot meets the county's minimum acreage and dimensions for its zoning.
- You show legal access, usually with a title report. Legal access means a public right of vehicular ingress and egress.
- A licensed surveyor or engineer states whether each lot has physical access a two-wheel-drive passenger car can use.
- You reserve eight-foot utility easements for sewer, electric, gas and water.
- You sign a sworn statement that you know it is unlawful to divide land into six or more lots by acting in concert with others.
Fail one of those and you may still get approval. A non-compliant split is approved if you sign an acknowledgment that the county will issue no building or use permit until the lot meets the requirements, and the county can note the access or zoning problem in the deed. That is one way a lot ends up legal to own but not yet legal to build on.
The six-lot line
Arizona treats six lots as a different thing. It is unlawful to avoid the subdivision law by dividing a parcel into six or more lots, or by selling or leasing six or more, through a series of owners or conveyances. Being related, by itself, does not count as acting in concert, but a series of owners can. If your plan is six lots, plan for a plat. How developers handle that is a separate process.
Inside a city
A city regulates every subdivision within its limits, and by ordinance it can require preliminary plats, utility standards and fees (A.R.S. 9-463.01). Cities write their own procedures by ordinance, so call the planning counter before you pay for a survey.
The steps
- Get the zoning from the county or city and check the minimum lot size. A parcel zoned for ten-acre minimums should not be cut into five-acre lots without a variance or the no-permit acknowledgment described above.
- Order a boundary survey and a preliminary title report. Surveyors price by the parcel, terrain and number of lots, so get two written quotes before you commit.
- Confirm legal access to every new lot. A lot behind another lot needs a recorded easement, or it is landlocked, and a landlocked parcel sells for less.
- File the division with the county and pay the fee. Fees are set by each county. Navajo County's application form, which we read on October 7, 2026, charges $430 for a split into two lots, $480 for three, $530 for four and $580 for five, and says the recorder's office charges separate fees for surveys. Ask your own county what it charges.
- Record the new deeds. The paperwork guide lists what a title company wants for each lot.
What the county does not decide for you
An approval can carry conditions. Under the statute the county may record the minimum access standards that must be met before a permit, and may list topographic or drainage limits that the lot owner has to address later. Wells and septic fields, which decide whether a lot can actually hold a house, are usually settled at the permit stage, not at the split. Ask for a conditions list before you divide.
Do split lots sell for more?
Per acre, yes, and the gap is large, but you need to read it carefully. In 21 Arizona towns, we have at least 25 recent sales of vacant parcels in both the 2-to-10-acre and the 10-to-40-acre bands. In 18 of those 21, the 2-to-10-acre median price per acre was at least double the 10-to-40-acre one:
- Show Low: about $24,400 an acre against $4,000.
- Prescott: about $80,300 against $19,950.
- Williams: about $9,000 against $2,400.
- Kingman: $6,400 against $2,000.
- Florence: about $27,300 against $8,250.
- Snowflake: about $9,000 against $1,740.
In three towns the gap closes: Eloy, Casa Grande and the City of Maricopa, where parcels near the growth edge are priced by what a builder will pay, not by size.
Two cautions. First, small parcels sit where people want them, so some of the premium is location, not size. Second, the survey, fees and any road work come out of the gain. A listing that advertises split potential sold for more per acre than one that did not, too: $38,000 against $22,000 at 2 to 10 acres. That comes from seller-written descriptions, so treat it as a hint. See Show Low if your parcel is in that market, and the price per acre tables for every county.
When to sell whole instead
If the parcel has no recorded access, a split multiplies the problem. If the survey and fees would eat most of the gain, which on cheap rural land they can, a split is a lot of work for little. And if you need to be done in weeks, a split takes the county's 30-day clock plus survey and recording time before you list anything. Send us the parcel number and we will price it as it sits; you can set that against what a split would net by running the land value lookup first.

Common questions
Do I need a plat to split land in Arizona? Not for five or fewer lots in a county that has adopted the staff-review process, under A.R.S. 11-831. Cities and six-or-more-lot divisions are different.
How long does a county lot split take? The statute gives the county 30 days to review, after which the division is considered approved.
Can I sell part of my land? Yes, but only after the division is approved and recorded, and each piece needs legal access.
