Sutter 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.
Yuba City FAQ
Does the 4-foot exemption include the footing?
Yes. The 4-foot measurement is from the bottom of the footing to the top of the wall, not from finished grade. A wall that appears 3.5 feet tall but has a 1-foot-deep footing measures 4.5 feet and requires a permit.
I want a 3-foot retaining wall with a 5-foot fence on top - is that one structure?
For fence-height purposes the City typically measures the combined assembly from natural grade. For permitting, the wall and fence are separate: the wall is permit-exempt at 3 feet, but the fence-on-wall combination must comply with the 8-foot side/rear height cap in Article 59.
