Ask c3gov - Permits & Licenses - Building license expiration
Does a building permit have an expiration date?
Building permits become null and void if work or authorized construction does not begin within 180 days of the issuance of the permit, or if construction or work is suspended or abandoned for a period of 180 days at any time after work begins. Extensions may be authorized by the City Building Official. Please call 303.289.3683 for more information.
