Anza FAQ
Murrieta FAQ
Can I build a 3-foot retaining wall without a permit?
Generally yes, if it retains only earth with no surcharge. Any driveway, patio, or slope above the wall is a surcharge that triggers a permit.
Can I put a fence on top of my retaining wall?
Yes, but the combined height may trigger additional review and the fence height is typically measured from the retained side.
