Lassen County, CA Fence Regulations: Height Limits (2026)

Lassen County regulates fence height through the General Provisions and Exceptions of its Title 18 zoning ordinance rather than a standalone fence code. In the R (residential) districts, fences, shrubs, hedges, screen plantings, and similar obstructions are limited to three feet in height within a required front yard and six feet in side and rear yards. An additional height may be permitted between side or rear yards not exceeding eight feet above the ground level of the lower property line, provided the portion of the fence extending above six feet is designed to permit adequate air circulation. These provisions do not prohibit shrubs, trees, or other ornamental plantings primarily intended for landscaping. On corner lots, a stricter three-foot limit applies within the sight distance area at intersections and driveways (see the neighbor-rules and material topics). Because exact standards vary by zoning district and yard location, and because some lots fall in agricultural rather than residential zones, owners should confirm the rule for their specific parcel with the Lassen County Planning and Building Services Department (221 S. Roop St., Susanville, 530-251-8333) before building. Susanville, the county's only incorporated city, sets its own rules and is not covered here.
