Fremont FAQ
Do I need a permit for a 6-foot wood fence?
No. Residential fences up to 7 feet are exempt from building permits but must still meet zoning setback and visibility rules.
What about a short retaining wall?
Retaining walls 3 feet and under (measured from footing) are permit-exempt. Taller walls need an engineered permit from the Building Division.

Not if replacing like-for-like up to 6 feet in the same location; upgrades in height or masonry materials trigger permits.
