Do I need a permit for foundation repair?
Most cities and counties treat structural foundation work (piers, underpinning, wall anchors, rebuilding a wall) as work that needs a building permit and inspection; sealing a small crack or mudjacking a sidewalk usually doesn't. Rules are local, so ask the contractor who pulls the permit and keep the final inspection record with your house papers.
