Understanding Building Permits

Building permits are official documents issued by local governments that give property owners the legal right to proceed with a construction project. They ensure that your project adheres to building codes and safety standards, protecting both you and your neighbors. Permits are typically required for new construction, additions, alterations, and repairs that affect the structural integrity of a building.
