(a)
Unless otherwise authorized, every permit issued by the Permit and Resource Management Department under the provisions of this section shall expire by limitation three (3) years from the date of permit issuance. The chief building official may limit a permit to a lesser time period when necessary to abate dangerous or substandard conditions. The chief building official may extend this time period when such extension is warranted, including but not limited to (1) to correct an error by the department, (2) when a legal action prevents the project from being completed within the three year time frame, or (3) in the interest of public health and safety. The chief building official's decision regarding the limitation period shall be final.
(b)
Before any work can be commence or recommenced on any expired permit, or permit to legalize a violation, a new permit shall first be obtained. The new permit shall be obtained for all work necessary to finish the project including work already completed that has not been previously inspected and approved by the department.
i.
Any new permits issued to recommence work started under an expired permit will be based on the codes in effect at the time of the original expired permit.
ii.
Any new permits issued to commence work under an expired permit will be based on the codes in effect at the time of the original expired permit, provided that no more than two subsequent model California Building Code s have been adopted.

Schedule of Permit Fees.

CCR Title 24, Part 5, 2016 CPC, Chapter 1, Division II, Section 104.5; and,
CCR Title 24, Part 10, 2016 CEBC, Chapter 1, Division II, Section 108.2;
are amended to read as follows:
Schedule of Permit Fees.
1.
Schedule of permit fees. On buildings, structures, electrical, gas, mechanical, and plumbing systems or alterations requiring a permit, a fee for each permit shall be paid as required, in accordance with the schedule as established by the Sonoma County Board of Supervisors.
2.
Incomplete Plans. Where plans are incomplete or changed so as to require additional plan review, an additional plan review fee shall be charged at the rate shown in the Permit and Resource Management Department fee schedule.
3.
Peer Review or Third Party Review. When approved by the chief building official a reduction in plan review fees by twenty five per cent (25%) of that otherwise required may be granted where a peer review or third party plan review or other process results in substantially reduced plan review effort by the Permit and Resource Management Department.
4.
Stock Plans. The chief building official may, in his or her discretion, waive the plan check fee for the second and all subsequent buildings or structures identical to a building or structure for which a plan check has been paid because there is a reduction in the cost of providing the service. This plan check fee waiver for subsequent submittals shall be limited to one (1) year following date of original fee payment. In each case the applicant must be the same for all permits.
5.
Reinspection Fees. A reinspection fee may be assessed for each inspection or reinspection when such portion of work for which inspection is called is not complete or when corrections called for are not made. This section is not to be interpreted as requiring reinspection fees the first time a job is rejected for failure to comply with the requirements of this code, but as controlling the practice of calling for inspections before the job is ready for such inspection or reinspection. Reinspection fees may be assessed when the inspection record card has not been posted or otherwise is not available on the work site, the approved plans are not readily available to the inspector, for failure to provide access on the date for which the inspection is requested, or for deviating from plans requiring the approval of the building official. The reinspection fee shall be established in the Board of Supervisors' fee schedule. When a reinspection fee has been assessed, no additional inspection of the work shall be performed until the required fees have been paid.
6.
Violation Penalty and Review Fee. Any person who violates a provision of this code or fails to comply with any of the requirements thereof or who erects, constructs, alters or repairs a building or structure in violation of the approved construction documents or directive of the building official, or of a permit or certificate issued under the provisions of this code, shall be subject to penalties as prescribed by law. A review fee equal to the amount of the permit fee, whether or not a permit is then or subsequently issued, shall be assessed. The payment of such review fee shall not exempt any person from compliance with all other provisions of this code nor from any penalty prescribed by law.
