What happens to permits if the work authorized is not commenced within 180 days of issuance?

When a permit is issued for mechanical work, there is a specific time frame within which the work must begin to maintain the permit's validity. According to the International Mechanical Code, if construction or work is not commenced within 180 days of the permit's issuance, the permit is considered to have expired. This timeframe is established to ensure that projects remain active and comply with current codes and standards, as well as to encourage timely progress in construction or renovation efforts.

The expiration of the permit means it becomes null and void, requiring the applicant to reapply for a new permit if they wish to proceed with the work. This policy helps maintain updated information in the permitting system and ensures that any applicable changes in codes are applied to the project moving forward.
