Building setbacks in unincorporated Maricopa County vary by zoning district. The Maricopa County Zoning Ordinance (MCZO) establishes minimum front, side, and rear setbacks for each district. Rural zones have larger setbacks than suburban residential zones. The updated 2026 MCZO maintains district-specific setback tables. Accessory structures must be at least 3 feet from side and rear lot lines.
Building setbacks in unincorporated Maricopa County are established by the MCZO and vary significantly by zoning district. In the Rural-43 zone, typical setbacks are 50 feet front, 30 feet side, and 50 feet rear; in R1-10 suburban residential, setbacks drop to approximately 25 feet front, 7 feet side, and 20 feet rear. Accessory structures must maintain at least 3 feet from side and rear property lines. The 2026 updated MCZO introduced reduced setbacks for ADUs, allowing them closer to property boundaries under certain conditions. Property owners can verify their specific zoning district and applicable setbacks through the Maricopa County Planning and Development Department at (602) 506-3301 or via the county's online zoning map viewer.
