Summary
Arizona law (ARS 36-1681) and the Surprise building code require barriers around all residential swimming pools. Pool barriers must be at least 5 feet high with self-closing, self-latching gates. Gaps must not allow a 4-inch sphere to pass through. Door alarms or approved safety covers are required for direct home access to pool areas.
A. A swimming pool, or other contained body of water that contains water eighteen inches or more in depth at any point and that is wider than eight feet at any point and is intended for swimming, shall be protected by an enclosure surrounding the pool area, as provided in this section.
B. A swimming pool or other contained body of water required to be enclosed by subsection A whether a belowground or aboveground pool shall meet the following requirements:
1. Be entirely enclosed by at least a five foot wall, fence or other barrier as measured on the exterior side of the wall, fence or barrier.
2. Have no openings in the wall, fence or barrier through which a spherical object four inches in diameter can pass. The horizontal components of any wall, fence or barrier shall be spaced not less than forty-five inches apart measured vertically or shall be placed on the pool side of a wall, fence or barrier which shall not have any opening greater than one and three-quarter inches measured horizontally. Wire mesh or chain link fences shall have a maximum mesh size of one and three-quarter inches measured horizontally.
3. Gates for the enclosure shall:
(a) Be self-closing and self-latching with the latch located at least fifty-four inches above the underlying ground or on the pool side of the gate with a release mechanism at least five inches below the top of the gate and no opening greater than one-half inch within twenty-four inches of the release mechanism or be secured by a padlock or similar device which requires a key, electric opener or integral combination which can have the latch at any height.
(b) Open outward from the pool.
4. The wall, fence or barrier shall not contain openings, handholds or footholds accessible from the exterior side of the enclosure that can be used to climb the wall, fence or barrier.
5. The wall, fence or barrier shall be at least twenty inches from the water's edge.
Full Breakdown
Arizona's pool barrier statute (ARS 36-1681) mandates safety barriers around all residential swimming pools. The City of Surprise enforces these requirements through its adopted building code. Pool barriers must be a minimum of 5 feet high and constructed to prevent climbing (no horizontal rails on the pool side). Openings must not allow a 4-inch sphere to pass through. Gates must be self-closing, self-latching, and open outward from the pool. Gate latches must be at least 54 inches above grade or have a release mechanism on the pool side requiring reaching over the gate. When the house wall serves as part of the barrier, all doors providing direct access to the pool must have door alarms or the pool must have an approved safety cover meeting ASTM F1346. Pool covers alone do not satisfy the barrier requirement. Surprise building inspectors verify barrier compliance during pool construction inspections and can inspect existing pools upon complaint.

Violations & Fines
Pool barrier violations are enforcement priorities due to child safety. Non-compliant barriers may result in immediate corrective orders, fines, and potential pool closure until compliance is achieved.
