Bakersfield FAQ
Do I need a permit for a 3-foot retaining wall?
Usually no, if the wall is 4 feet or less measured from the bottom of the footing and does not support a surcharge like a driveway or pool. It must still meet property setbacks. Check with Development Services if there's any surcharge.
Does my retaining wall need engineered plans?
Yes if it exceeds 4 feet in height or supports any load. Bakersfield requires stamped plans from a California-licensed civil or structural engineer, along with drainage provisions, for walls over 4 feet.
Delano FAQ
Do I need a permit for a 3 foot retaining wall?
Generally no, unless it supports a surcharge such as a driveway, slope above, or structure. Many cities still require setbacks and drainage even when permits are not required.
Can my city require permits for shorter walls?
Yes. The California Building Code is a floor, not a ceiling. Local jurisdictions can adopt stricter thresholds, like requiring permits for walls over two or three feet.
