Maricopa County zoning ordinance governs fence materials in unincorporated areas. Block/masonry walls are extremely common due to the desert climate providing privacy, heat reduction, and security. Barbed wire is allowed only in agricultural and rural zones. Chain-link fencing is permitted but may have screening requirements in some zoning districts.
Unincorporated Maricopa County does not impose blanket fence material restrictions outside of zoning overlay districts. Where zoning applies, the county may restrict chain-link visibility from public rights-of-way and require desert-compatible materials in scenic corridor overlays. UV-resistant and heat-tolerant materials such as block, stucco, wrought iron, and powder-coated metal perform best in the extreme desert climate. Wood fencing degrades rapidly under sustained 115-degree heat and intense UV exposure common in the Phoenix metro area. Property owners should check with Maricopa County Planning and Development at (602) 506-3301 and any applicable HOA for material requirements.
Specific penalty amounts for this ordinance are not published in a publicly accessible fine schedule. Contact Maricopa County code enforcement directly for current fines, enforcement procedures, and hearing options.
