Foundation Repair · St. Mary's County, Maryland
In Maryland, 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 + local code (IRC 2021); apply through Montgomery County Department of Permitting Services before work begins.
