Tuolumne County requires building permits for retaining walls per the California Building Code. The county's Sierra foothill terrain frequently necessitates retaining walls for slope stabilization and development grading.
Tuolumne County requires building permits for retaining walls, particularly those over 4 feet in height (measured from bottom of footing to top of wall) or those supporting a surcharge. The county's mountainous terrain in communities like Twain Harte, Mi-Wuk Village, and Groveland means retaining walls are common for lot development and erosion control. Walls over 4 feet require engineered plans. The Building Department reviews retaining wall permits for structural adequacy, drainage provisions, and setback compliance. Grading permits may also be required if significant earthwork is involved per the county's grading ordinance.
Building without permit: stop work order and retroactive permit with penalty fees. Contact Building Department at 209-533-5633.
