Carmichael FAQ
Do I need a permit for a 3-foot Carmichael retaining wall?
Not if it retains 4 feet of soil or less and has no surcharge above it. A 3-foot wall with a sloping landscape above can require a permit because of the surcharge.
Herald 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.
