Fremont, CA Fence Regulations: Fence Permit Requirements (2026)

Fremont Municipal Code Section 18.171.030(a) draws a clear line for when fence work needs city sign-off: fences over seven feet in height, concrete and masonry walls over four feet in height, and retaining walls of any height all require a building permit before construction. Because the general height limits in Section 18.171.010 cap ordinary residential fences at eight feet in side/rear yards and 48 inches in front yards, most standard wood or chain-link yard fencing falls under the seven-foot permit trigger and can go up without a permit, but any fence approaching or exceeding that eight-foot maximum, or a masonry or block wall over four feet, needs plan review and a permit from the Fremont Building Division.

The same section adds finish and safety conditions tied to the permit review. A fence facing a public right-of-way that has a finished side must be oriented so the finished side faces the street, and sound walls facing a right-of-way must be treated with anti-graffiti paint or a maintained landscape buffer. Fences over eight feet or masonry walls over four feet that exceed the base height limits also require the separate height exception findings under Section 18.171.060, reviewed by the zoning administrator, in addition to the building permit for the construction itself. Design of fencing requiring a permit must also be consistent with the citywide design guidelines referenced in Section 18.171.040.
