A.    Except as otherwise provided for in this chapter, the California Residential Code, 2016 Edition, including the appendices thereto, together with those omissions, amendments, exceptions and additions thereto are approved and adopted, and hereby incorporated in this chapter by reference and made a part hereof the same as if fully set forth herein.

B.    One copy of the CRC has been filed for use and examination of the public in the office of the building official of the city of Marina.

C.    Findings. The amendments set forth in Sections 15.14.020, 15.14.030, 15.14.040, 15.14.050, 15.14.060, 15.14.070, 15.14.080 and 15.14.090 are reasonably necessary because of the following local geological, topographical and climatic conditions:

1.    Marina is within a very active seismic area (Seismic Zone 4). Severe seismic action could disrupt communications, damage gas mains, cause extensive electrical hazards, and place extreme demands on the limited and widely dispersed resources of the fire department, resulting in failure to meet the fire and life safety needs of the community.

2.    The local geographic, topographic and climatic conditions pose an increased hazard in the acceleration, spread, magnitude, and severity of potential fires in the city of Marina, and may cause a delayed fire response time, allowing further growth of the fire.

3.    The type of residential construction provisions set forth in the amendments are more restrictive standards, which will better prevent fire and seismic damage, which can result from local conditions. (Ord. 2016-05 § 1 (Exh. A (9) (part)), 2016)

Section R105.5 is hereby amended to read as follows:

R105.5 Expiration of Permits. Every permit issued by the building official under the provisions of the technical codes shall expire and become null and void, if the project authorized by such permit has not achieved an approval for one of the required inspections identified in section 110.3 of the 2016 California Building Code within one year of such permit.

The building official may grant a one-time permit extension of 180 (one hundred eighty) days provided the applicant submits a request in writing prior to the permit expiration and the project has not changed in scope. Additional extension requests of one hundred and eighty (180) days may be granted by the building official if the request is made in writing, the project has not changed in scope, the project has obtained at least one inspection approval AND the applicant pays a fee of $1,000 or the amount of the original building permit fee for each one hundred and eighty (180) day extension.

Before work can commence or recommence under an expired permit, a new permit application must be submitted and permit obtained along with all applicable fees applied for this new project.

All existing projects are subject to this section and will be subject to the conditions listed above.

15.14.040 Section R106.6 amended.

Section R106.6 is hereby amended to read as follows:

R106.6 Expiration of Plan Review. Applications for which no permit is issued within 180 days following the date of the application shall expire, and plans and other data submitted for review may thereafter be returned to the applicant or destroyed by the building official. The building official may extend the time for action by the applicant for a period not exceeding 180 days on written request by the applicant showing that circumstances beyond control of the applicant have prevented action from being taken and the extension has been submitted in writing prior to the expiration date.

If a permit has not been obtained after the first extension, additional extensions of 90 days may be granted provided the applicant submits this request in writing and pays a fee of $500.00 for each requested 180-day extension and the project has not changed in scope.

Exception: If a project has been approved by the City pending an outside agency approval prior to expiration, written extensions will not be required.
