The City of Orange regulates maximum lot coverage through OMC Title 17 (Zoning) residential district standards. Lot coverage limits vary by zoning district and include all roofed structures including the main dwelling, garages, carports, and accessory structures.
Under OMC Title 17, each residential zoning district specifies a maximum lot coverage percentage that limits the total footprint of all roofed structures relative to the total lot area. Coverage includes the main dwelling, attached and detached garages, carports, covered patios, and all accessory structures. Typical single-family residential zones allow coverage ranging from 40% to 50% depending on the specific zone designation. Lot coverage is calculated as the total area of all structures divided by the total lot area. Projects exceeding the maximum coverage require a variance through the Planning Commission.
Exceeding maximum lot coverage may result in denial of building permits, code enforcement action, or required modification or removal of non-conforming structures.
