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

Glenn County's Title 15 Unified Development Code (adopted September 27, 2018) governs fences in unincorporated areas. Title 15 defines fence height as the vertical distance from the ground level of the property line (or the public-property ground level nearest the line) to the highest point of the fence, and where a property line separates lots of unequal grade, the lowest level is used to measure height. The most specific numeric fence-height rule appearing in the code applies in required vision-clearance (sight-distance) areas near intersections and driveways: there, a fence or wall may be allowed to exceed three feet only up to a height of four feet, and the additional one foot above three feet must not be of solid material so visibility is preserved. Outside those sight areas, ordinary residential boundary fences are limited primarily by the California Building Code permit threshold (fences not over 7 feet are exempt from a building permit) and by the zone's yard and setback standards. Because Glenn County is largely rural and agricultural, no single county-wide maximum residential fence height is published the way an urban code would; confirm specifics with the Glenn County Planning & Community Development Services Agency for your zone.
