Do I need a permit for a retaining wall in San Bernardino?
A retaining wall 4 feet tall or less, measured from the bottom of the footing to the top of the wall, doesn't need a building permit in San Bernardino unless it carries an added load like a slope or driveway above it or holds back certain liquids. Past that height, or with a load above it, the wall goes through the city for a permit. Because the height counts from the footing, a wall that shows about 3 feet above the dirt can already be past the line, so I measure that with you at the estimate.
