Building Permits


Building permits are in place for your safety - and the safety of those around you, ensuring your construction project is protected from structural failure, fire hazards from electrical and heating systems, electrical shock and other health risks. They also provide a permanent record of the work performed and all inspections conducted to ensure the project is sound and safe.

Before starting a new construction project -- either indoors or outdoor -- you must determine whether you need a building permit.
