What must happen before a permit can be considered valid?

A permit is considered valid when the work must commence within a specified time frame. This requirement is crucial as it establishes a timeline for the project, ensuring that construction begins promptly after the permit has been issued. Permits have a defined duration of validity, which varies by jurisdiction, so starting the work on time is key to maintaining compliance with local regulations.

If the work does not begin within the specified period, the permit may lapse or become invalid, potentially requiring the contractor to apply for a new permit. This process helps maintain oversight of construction activities and ensures that projects are initiated in a timely manner to adhere to safety standards and building codes.

The other options do not reflect the correct point of validity for a permit. For instance, completion of the project or passing all inspections is not necessary for the permit's validity but rather for its closure or completion. Payment of a fine is also not a standard requirement for a permit's validity but might occur if there are violations. Thus, commencing work within the designated timeframe is the correct condition for a permit to be considered valid.
