5 rules for unincorporated Pinal County, Arizona.
Verified from official government sources
Unincorporated Pinal County requires a building permit to install a residential swimming pool, and the required perimeter barrier must be inspected and pass final inspection before the pool is filled with water.
Every residential pool in unincorporated Pinal County must be enclosed by a perimeter barrier at least 60 inches (5 feet) high, mirroring Arizona's statewide pool-enclosure law A.R.S. 36-1681.
A.R.S. 36-1681(B)(1)-(2)
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. ... Have no openings in the wall, fence or barrier through which a spherical object four inches in diameter can pass.
Pinal County pool safety rules require self-closing, self-latching gates that open away from the pool, plus a self-latching device, alarm, or intermediate barrier on any house door that opens directly to the pool.
A.R.S. 36-1681(B)(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... (b) Open outward from the pool.
An above-ground pool in Pinal County must still meet the 60-inch barrier rule; if the pool wall itself serves as the barrier, the ladder or steps must be lockable or removable to block child access.
A spa or hot tub in Pinal County may skip the 5-foot pool barrier only if it is no wider than 8 feet and uses an approved, lockable safety cover that supports 100 pounds and blocks a 4-inch sphere.
