Every permit issued becomes invalid if the authorized work is not commenced within how many days?

The correct choice highlights that a permit issued for construction or renovation becomes invalid if the authorized work is not commenced within 180 days. This time frame is commonly established in building codes and regulations to ensure that projects are actively progressing.

Permits are a way for municipalities to monitor the development of construction projects and ensure that these projects adhere to local building codes and zoning laws. By establishing a 180-day window, it promotes timely commencement and prevents delays that could lead to safety issues, project stagnation, or changes in plans that might conflict with initial approvals. Moreover, this period allows permit holders adequate time to coordinate their preparations and mobilize resources without overly restrictive timelines, balancing efficiency with practical considerations in the workflow of construction projects.

Thus, should the work not commence within this prescribed period, the validity of the permit is forfeited, typically requiring the application of a new permit for the planned construction or renovation to proceed legally.
