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

Because Mariposa County is entirely unincorporated, fence materials are not restricted by any city code. For rural parcels, the Planning Department states it has no jurisdiction over the placement of a fence, and no general countywide ordinance dictates approved fence materials; standard wood, wire, chain-link, and similar materials are commonly used. The County does, however, apply Design Review inside adopted Town Planning Areas. The Planning Department notes that a fence within a Town Planning Area may require Design Review for height, structure, and design materials. This is most significant in the design-review and historic design-review overlay zones in and around the Town of Mariposa, where the zoning ordinance (Mariposa County Code Chapter 17.336, Sections 17.336.060 through 17.336.075) establishes architectural theme and development guidelines intended to preserve community and historic character. Within those overlay zones, the appearance and materials of fences and walls can be reviewed for compatibility. Wildfire considerations may also influence material choices near structures under defensible-space and Wildland-Urban Interface standards. Confirm whether your parcel lies within a Town Planning Area or overlay zone before selecting fence materials.
