Tuolumne County, CA Fence Regulations: Material Restrictions (2026)

For ordinary residential fences in unincorporated Tuolumne County, Title 17 does not prescribe permitted or prohibited fence materials, so common choices such as wood, vinyl, chain link, wrought iron, and masonry block are generally allowed, subject to height and placement rules. Material-related standards appear mainly in two contexts. First, for commercial and multifamily development, the county's objective design standards require refuse enclosures to be 'constructed of the same primary wall material and color as the most adjacent building,' with opaque gates, and require loading-area screening by 'a six-foot wall, fence, or evergreen.' Second, parcels in Historic Combining (H) or Historic Design Preservation (HDP) districts are subject to design review, where fence and wall materials may need to match the historic character of the area. Because the county also lies within State Responsibility Area and wildfire-prone terrain, the California Building Code's wildland-urban interface and fire-resistant material requirements may influence fences attached to or near dwellings; the county's defensible-space standards limit combustible materials close to structures. Always verify any project against the building code and, in historic or commercial zones, with the Community Resources Agency.
