In Wyoming, 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.
