CBC section 105.5 and CRC section R105.5 is clarified to provide that every permit issued shall become invalid unless the work on the site authorized by such permit is commenced within 180 days after its issuance, or if the work authorized on the site by such permit is suspended or abandoned for a period of 180 days after the time the work is commenced. The building official is authorized to grant, in writing, one or more extensions of time, for periods of not more than 180 days each. The extension shall be requested in writing and justifiable cause demonstrated. The extension shall not be valid until fees prescribed have been paid in accordance with the percentage of level of completion which is based on the building permit fee. Every permit issued by the building official under the provisions of the California Building Code shall expire and become invalid three years from the date of issuance. The building official is authorized to grant, in writing, one or more extensions of time, for periods not more than 180 days each. The maximum validity of a permit shall not exceed four years. An extension shall not be valid until fees prescribed have been paid in accordance with the percentage of level of completion which is based on the building permit fee. Before any work can be recommenced on an expired permit, a new permit shall be obtained. On permits expired for one year or more, the codes in effect at the time a new permit is issued shall be the codes which apply to that permit through the point of completion or expiration.
