Elfin Forest FAQ
Do I need a permit for a retaining wall in unincorporated San Diego County?
Yes, if the wall exceeds 3 feet from the top of the footing to the top of the wall, or if it supports any surcharge (weight, fill, or structures above it). Walls over 4 feet of exposed height require professional engineering.

A surcharge is any weight or pressure behind the wall, such as fill material, a slope, a driveway, a building, or a fence on top. Even short walls need permits if they support a surcharge.
