Do I need a permit for retaining wall construction in Milpitas?

Permit may be required

It depends. Whether retaining wall construction needs a permit in Milpitas comes down to the details of your project.

Retaining walls not over 4 feet tall, measured from the bottom of the footing to the top of the wall, are exempt from a building permit unless they support a surcharge (CRC R105.2 Building item 3). A taller wall, or any wall supporting a surcharge, needs a building permit; retaining walls are Group U structures under the CRC (1.1.3.1.1). Grading and drainage permits are set by cities and counties, and local amendments may change the exemption, so confirm with the local building department.
