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.
Reedley FAQ
Do I need a permit for a retaining wall in Reedley?
Yes, if the wall exceeds 4 feet from the bottom of the footing to the top, or if it supports a surcharge load (driveway, slope, or structure above). Shorter decorative or garden retaining walls typically do not need a permit.
Can I put a fence on top of a retaining wall?
Yes, but the combined height of the retaining wall and fence must comply with Chapter 10.34 height limits. In many cases the total height measured from the higher grade side determines compliance with front-yard or side-yard maximums.
