Manteca, CA Accessory Structures: Carport Rules (2026)

Manteca Municipal Code Title 17, Chapter 17.40 establishes Accessory Structures rules covering detached garages, carports, greenhouses, storage buildings, and similar features. Section 17.40.040 (Development Standards), implemented through Table 17.40.040-1, sets the dimensional standards by structure type. The Code defines a Covered Patio (which includes carports) as an accessory structure not exceeding 15 feet in height that is enclosed on no more than three sides, except for the posts necessary to support the roof. Accessory structures may be constructed only in conjunction with or after construction of the primary building on the site, except in agricultural zoning districts where they may precede the primary residence. The total footprint of all accessory structures on a lot may not exceed 30 percent of the actual rear yard area, and minimum separation between buildings must comply with the City-adopted Building Code. Setback distances are measured to any portion of the structure, including overhangs, projections, and railings. Exact minimum yard setbacks for a carport vary by zoning district (R-1, R-2, R-3, etc.) and lot configuration; the controlling district setbacks are in Chapter 17.26 (Development Standards by Zoning District), and yard measurements and projections rules are in the Yard Measurements and Projections section. Manteca's Planning Division advises confirming the exact setback for a specific parcel because numbers vary with zoning and lot size. Building permits and any required electrical permits are issued through the Development Services Building Safety Division. State law CA Government Code 65852.2 (ADU statute) does not directly govern carports, but a carport that is converted to enclosed living area must meet ADU/JADU standards. Because Manteca is incorporated, San Joaquin County zoning does not apply.
