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).
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.
