Glenn County, CA Fence Regulations: Fence Requirements (2026)

Fence requirements in unincorporated Glenn County come from the Title 15 Unified Development Code rather than a single standalone fence chapter. Title 15 defines how fence height is measured (from the ground level of the property line, using the lowest grade where lots differ) and imposes a vision-clearance standard near intersections and driveways: within those sight areas a fence or wall may exceed three feet only up to four feet, and the upper foot must not be solid so visibility is preserved. Title 15 also includes zone-based screening and buffering requirements. For example, in industrial zones where a parcel lies within a block partly in a residential district, the code requires a setback with a solid wall, solid fence, or landscaping where the rear of the lot abuts a residential district (a 25-foot rear yard with screening is required in that situation). Decorative screens, fences, ornamental post lamps, and decorative paving are treated as landscaping elements under the code. There is no published urban-style requirement that residential lots be fenced, and on large agricultural parcels fencing practices follow rural norms. Because requirements vary by zone, confirm the screening, height, and placement rules that apply to your specific parcel with Glenn County Planning & Community Development Services.
