Older pools
Pools permitted before May 4, 1990
Some Ahwatukee pools predate the current barrier rules. Phoenix explains how they are treated.
This is an independent referral guide. It connects homeowners with independent providers and may receive compensation. It is not a licensed contractor and it does not do the work.
The basics
Inner yard barriers are required for all new pools permitted after May 4, 1990. For single family pools, Phoenix says a barrier is required whenever children under six become occupants, even for pools built before 1990.
Grandfather clause
For pools permitted before May 4, 1990, existing inner barriers at least 4 feet high that met prior standards may stay. New fences must be 5 feet high.
Remodels
Additions or alterations to any part of the enclosure must meet the current standard. Changing a door that is part of the barrier means it must self close.
Removing it
Phoenix says the barrier may not be removed when a child grows up or moves away.

Say the neighborhood or ZIP code, the yard size, and whether the lot slopes or backs onto open desert.
