Fresno FAQ
Do I need a permit for a 3-foot retaining wall in Fresno?
Generally no, if under 4 feet measured from the bottom of the footing and not supporting a surcharge such as a driveway or slope above. If any surcharge applies, a permit is required at any height.
Who pays for a shared retaining wall on a Fresno property line?
Generally the uphill owner benefits most and may bear primary responsibility, but CA Civil Code §841 can apply if the wall is truly shared. Engineering and maintenance costs are often allocated by benefit in court.
Sanger FAQ
Do I need a permit for a retaining wall in Sanger?
Yes, if the wall exceeds 4 feet from the bottom of the footing to the top. Walls supporting driveways, structures, or slopes may need permits regardless of height.
Can I put a fence on top of my retaining wall?
Yes, but the combined height of the retaining wall and fence counts toward the maximum fence height for zoning purposes. A tall combination may require a variance.
