Tulare FAQ
Can I build a 3-foot retaining wall myself without a permit?
Usually yes — walls 4 feet or less measured from the bottom of the footing to the top are permit-exempt in Tulare, as long as no surcharge sits on the retained soil (no driveway, structure, or steep slope above).
My yard slopes up to my neighbor's. Do I need engineering?
An upslope above the wall is a surcharge, which removes the 4-foot permit exemption regardless of wall height. You will need engineered plans and a building permit.
Visalia 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.
