Arizona Pool Fence Requirements at a Glance
State and local laws change. This information reflects our best research as of September 2026, but you must confirm current requirements with your local building department before installing or modifying any pool barrier. Arizona's pool statute gives way to any city or county ordinance that is equal to or stricter than it (ARS 36-1681).

Arizona Pool Barrier Law
Arizona sets its pool barrier rule in state law. Arizona Revised Statutes (ARS) §36-1681 covers any pool or other contained body of water that is 18 inches or more deep at any point, wider than 8 feet at any point, and intended for swimming, whether it sits in the ground or above it.
The enclosure around the pool must meet all of these requirements:
- At least 5 feet (60 inches) high, measured on the outside of the barrier [ARS §36-1681(B)(1)]
- No opening a 4-inch sphere can pass through. Horizontal members must be at least 45 inches apart or sit on the pool side, and chain link or wire mesh can be no larger than 1¾ inches [ARS §36-1681(B)(2)]
- Gates self-closing and self-latching, with the latch at least 54 inches above the ground, or on the pool side with the release at least 5 inches below the top of the gate, or secured by a key, electric opener or combination lock at any height [ARS §36-1681(B)(3)(a)]
- Gates open outward, away from the pool [ARS §36-1681(B)(3)(b)]
- No openings, handholds or footholds on the outside that could be used to climb it [ARS §36-1681(B)(4)]
- At least 20 inches from the water's edge [ARS §36-1681(B)(5)]
Where the house forms part of the enclosure, the statute requires one of four added protections:
- A wall, fence or barrier at least 4 feet high between the house and the pool that meets the other barrier rules
- A motorized safety pool cover operated by a key switch and meeting ASTM International (ASTM) emergency standard ES 13-89
- Self-latching devices on every door with direct access to the pool, a latch at least 54 inches above the floor on sleeping-room emergency escape windows, and on other windows a screwed-in wire mesh screen, a keyed lock that limits the opening to 4 inches, or a latch at least 54 inches up
- An above-ground pool with non-climbable sides at least 4 feet high (see below) [ARS §36-1681(C)]
The statute does not apply to pools built before it took effect, to homes where every resident is at least 6 years old, or to public and semi-public pools. It also steps aside in any city or county that adopted its own barrier ordinance first, or adopts one that is equal to or stricter than state law. That is why Phoenix, Scottsdale and Maricopa County publish their own rules, covered below. [ARS §36-1681(D)]
A violation is a petty offense. No fine may be imposed if, within 45 days of the citation, you equip the pool with a compliant barrier and attend an approved swimming pool safety course. Anyone who builds a pool, or sells, rents or leases a home with one, must also give the buyer or renter a pool safety notice approved by the Arizona Department of Health Services. [ARS §36-1681(E), (F)]
Above-Ground Pools: Same Rules Apply
ARS §36-1681 covers above-ground pools. Subsection B applies to a pool whether it is belowground or aboveground, as long as it is at least 18 inches deep and wider than 8 feet.
The statute gives above-ground pools one specific option where the house forms part of the enclosure: the pool itself can serve as the inner barrier if its exterior sides are non-climbable and at least 4 feet high, and any ladder or steps can be removed without tools and are secured out of reach with a latch at least 54 inches above the ground when the pool is not in use. The outer 5-foot enclosure still applies.
Cities and counties with their own ordinance can set different details. Unincorporated Maricopa County, for example, requires a barrier for any contained body of water over 18 inches deep.
Above-ground pool setups vary. Always confirm your specific configuration with your local building department before installation.
City & County Variations in Arizona
The statute steps aside where a city or county has its own ordinance that is equal or stricter, so your exact rules depend on where you live. The rows below come from each jurisdiction's own documents. Where we have not verified the local details, we point you to our city guide or your building department.
| City / County | Requirements & Permit Notes |
|---|---|
| Phoenix Maricopa County | Phoenix applies the 2024 International Swimming Pool and Spa Code (ISPSC) with City of Phoenix amendments. Under Ordinance G-7397 (in effect August 1, 2025) the barrier must be at least 60 inches high on the outside, held for 3 feet out, with a bottom gap of no more than 2 inches, or 4 inches over a solid surface such as concrete. Mesh fencing must meet ASTM F2286. Gate latches sit at least 54 inches up. Pools permitted after May 4, 1990, and any single-family pool accessible to children under 6, also need a barrier between the house and the pool: an inner fence, the house wall with self-closing, self-latching doors and secured windows, or an ASTM F1346 motorized cover. Permit: The barrier is inspected at the pre-plaster inspection. A new permit is needed to alter, remove or replace an approved barrier. |
| Unincorporated Maricopa County | County Local Additions to the building code require a barrier for any contained body of water deeper than 18 inches or wider than 8 feet: at least 60 inches high, a bottom gap of 2 inches (4 inches over concrete), and a latch at 54 inches or on the pool side at least 3 inches below the top. With building official approval, an alarmed door can stand in for a separate barrier gate. Permit: The barrier permit must be issued before you install the barrier, plaster the pool, or fill it. |
| Scottsdale | Scottsdale amends the 2021 ISPSC: the barrier must be at least 60 inches high, and that height must hold for 3 feet out from the barrier. Door and window alarms, where used, must be listed to UL 2017 and sound within 7 seconds for at least 30 seconds. |
| Mesa | Mesa applies the 2024 ISPSC with Mesa amendments (pool and spa checklist): a barrier at least 60 inches high, held for 4 feet out; 60-inch construction fencing from excavation; 11-gauge chain link; no pet doors in a house wall that is part of the barrier. Pools built before April 20, 1998 are excepted unless the house is altered. |
| Tucson Pima County | The City of Tucson applies the 2024 ISPSC (Ordinance 12171, in effect January 1, 2026) without changing its 48-inch base height. Unincorporated Pima County adopted the 2024 ISPSC with county amendments (Pima County Code 15.04.020, in effect January 1, 2026); its amendments (Ordinance 2025-15, Exhibit J) widen which pools are covered but leave the 48-inch height. Both are lower than the statute's 60 inches, so ask the permit office which height it inspects to; a 60-inch barrier meets both. |
| Other cities | Ask your building department whether your city has its own barrier ordinance. If it does not, ARS §36-1681 applies as written. |

Arizona Pool Fencing: A State Statute With Local Overrides
Arizona is one of the few states where a statute, not just a building code, sets the pool barrier rule. ARS §36-1681 applies statewide, but it gives way to local ordinances that are equal or stricter, and the largest jurisdictions have used that room. Phoenix, Scottsdale and unincorporated Maricopa County each publish their own requirements, and most of them add detail the statute leaves out, such as bottom-gap limits and mesh standards.
The state penalty is lighter than many homeowners expect. A violation is a petty offense, and the statute bars any fine if you fix the barrier within 45 days of the citation and complete an approved pool safety course. Master-planned communities across the Valley can add homeowners' association (HOA) design rules on top of code, so an installer may need to satisfy both.
