Tempe's Zoning and Development Code establishes maximum lot coverage limits that vary by zoning district. Lot coverage includes the footprint of all structures (main dwelling, accessory buildings, carports, patios with solid roofs). In single-family residential districts, typical maximum lot coverage ranges from 35-45% depending on the specific zone. Accessory structures and ADUs count toward lot coverage calculations.
Lot coverage in Tempe is regulated by the Zoning and Development Code, with maximum percentages varying by zoning district. Single-family residential zones typically allow 35-45% lot coverage. Multi-family zones may allow higher coverage. Lot coverage includes the footprint of the primary dwelling, garages, carports, accessory buildings, and any roofed structures (including solid patio covers). Open-lattice patio covers and pergolas may be excluded from coverage calculations depending on the percentage of open area. Swimming pools are generally not counted toward lot coverage. Accessory dwelling units (ADUs) count toward lot coverage calculations. The Zoning and Development Code also establishes floor area ratio (FAR) limits in some districts. Exceeding lot coverage requires a variance from the Board of Adjustment. Tempe's Community Development department calculates lot coverage during plan review for all building permits.
Exceeding maximum lot coverage without a variance may result in denial of building permits and orders to reduce building footprint.
