Clovis FAQ
Do I need a permit for a 3 ft retaining wall?
Not if it supports only its own soil. If it retains a driveway, pool, or structural surcharge, a permit is required regardless of height.
How high can a retaining wall be in Clovis?
No specific city maximum, but walls over 4 ft require engineered design and permit. Combined fence-on-wall setups must still meet the zoning fence height (typically 6 ft above the wall top is common).
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.
