Mariposa County, CA Accessory Structures: Carport Rules (2026)

Under Mariposa County Code section 17.108.130 (Structure Location), carports are generally subject to the same setbacks as other structures: 25 ft front, and 25 ft or 10% of lot width/depth (whichever is less) on the sides and rear. However, subsection D specifically lists 'Garages, carports, sheltered parking, and covered walkways' among uses that may be constructed in front-yard areas, but only where: (a) the site is above four thousand (4,000) feet in elevation; (b) 'Carports shall have no enclosing walls higher than three (3) feet above ground level'; and (c) for garages, sight-distance standards are met and the location is approved by the Public Works road division (no variance to these standards is allowed). This front-yard allowance reflects the County's high-elevation, snow-prone Sierra terrain near Yosemite. A carport that is a roofed structure over 120 sq ft is subject to the structure-location standards, and maximum structure height is 35 feet (Sec. 17.108.140). Confirm permit requirements with the County Building Department before construction.
