Foundation Repair · Orange County, California
In California, a Foundation Repair requires a building permit.
Structural foundation repair such as underpinning, piers, wall reinforcement, or leveling requires a building permit and inspection, often with engineered drawings. Minor cosmetic work such as sealing small cracks or waterproofing usually does not. Plans are reviewed under the Statewide (CA Codes) code (IRC 2024); apply through Orange County Public Works before work begins.
