Florin FAQ
Is a 3-ft garden wall exempt?
Yes, if it supports no surcharge and is under 4 ft. Stacking multiple short walls to total over 4 ft may still trigger engineering review.
McClellan Park 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.
