Full Breakdown
Above-ground pools in unincorporated Maricopa County must comply with Arizona's pool barrier law (ARS 36-1681), which requires a physical barrier at least five feet high enclosing the pool area with self-closing, self-latching gates. Pools with a water depth of 18 inches or more are subject to these requirements. A building permit from Maricopa County Planning and Development is required for permanent above-ground pool installations including associated electrical and plumbing work. In the extreme Maricopa County heat where summer temperatures regularly exceed 110 degrees Fahrenheit, pools are heavily used and barrier compliance is aggressively enforced to prevent child drowning incidents.
