Maricopa County Planning and Development reviews fence and wall permits for unincorporated areas. Block walls over 6 feet require a building permit and may need structural engineering. Pool barrier fences require compliance with ARS §36-1681. Standard fences under 6 feet generally do not need permits.
Maricopa County Planning and Development handles fence and wall permits for unincorporated territory. Block walls (CMU) over 6 feet in height require a building permit with structural engineering plans. Standard fences under 6 feet in non-setback areas generally do not require permits. Pool barrier fences must comply with ARS §36-1681 requirements regardless of height. Retaining walls over 4 feet in retained earth height require engineering review. Fences within utility easements or flood control easements may require additional approvals from the respective agencies. FCDMC (Flood Control District of Maricopa County) has jurisdiction over walls and fences within its easements. HOA Architectural Review Committees often require pre-approval for any fence or wall construction.
Building without permit: stop-work order, retroactive permit fees, potential removal order. Pool barrier non-compliance: immediate correction required.
