Arizona Statewide Pool Barrier and Fencing Law

A.R.S. Section 36-1681 requires barriers around pools and contained bodies of water exceeding 18 inches in depth at single-family residences in counties of 250,000 or more. The barrier must be at least five feet high, with no openings allowing a four-inch sphere to pass through, and gates must be self-closing and self-latching with the latch at least 54 inches above ground. Doors from a residence directly into the pool area must have audible alarms or self-closing, self-latching mechanisms. Cities and counties may adopt stricter requirements but cannot reduce these state-mandated minimums.

Violations are typically civil infractions with fines, plus potential civil liability for any drowning or injury caused by inadequate barriers.
