When is a permit required for construction work?

A permit is required for any work that affects the structure, occupancy, or safety of a building because this ensures that all construction meets the necessary codes and standards set by local regulations. This requirement is in place to protect the safety of the occupants and the integrity of the building itself. Structural changes, such as altering load-bearing walls, changing the building's footprint, or making significant modifications to the electrical or plumbing systems, could potentially create hazards if not executed correctly and inspected accordingly.

In contrast, cosmetic changes generally do not require a permit as they do not affect the structural integrity of a building or its safety. The requirement for permits is also not limited strictly to commercial projects; residential projects may also necessitate permits for various types of work. Lastly, while roofing jobs may require permits depending on the extent of the work, it is not universally true that all roofing jobs need one, particularly minor repairs. Thus, the overall requirement for permits is tied closely to any activity that could impact safety or occupancy.
