(d) Expiration. Every permit issued by the Building Official under the provisions of this code shall expire by limitation and become null and void, if the building or work authorized by such permit is not commenced within 180 days from the date of such permit, or if the building or work authorized by such permit is suspended or abandoned at any time after the work is commenced for a period of 180 days. Before such work can be recommenced, a new permit shall be first obtained, and the fee therefor shall be one half the amount required for a new permit for such work, provided no changes have been made or will be made in the original plans and specifications for such work; and provided further that such suspension or abandonment has not exceeded one year.

The payment of such investigation fee shall not exempt any person from compliance with all other provisions of this code or from any penalty prescribed by law.

(c) Fee Refunds.

(1) The Building Official may authorize the refunding of any fee paid thereunder which was erroneously paid or collected.

(2) The Building Official may authorize the refunding of not more than 80 percent of the permit fee paid when an application for a permit for which a fee has been paid is withdrawn or canceled before any work has been done.

(3) The Building Official shall not authorize the refunding of any fee paid except upon written application filed by the original permittee within 180 days from the date of fee payment.

25. Inspections.

(a) General. All electrical systems and equipment for which a permit is required by this code shall be subject to inspection by the Building Official, and the electrical system shall remain accessible and exposed for inspection purposes until approved by the Building Official.

It shall be the duty of the permit applicant to cause the electrical system to remain accessible and exposed for inspection purposes. Neither the Building Official nor the jurisdiction shall be liable for the expense of removing or replacing any material to permit inspection. When the installation of an electrical system and equipment is complete, an additional and final inspection shall be made. Electrical systems and equipment regulated by this code shall not be connected to the energy source until authorized by the Building Official.

Approval as a result of an inspection shall not be construed to be an approval of a violation of the provisions of this code or of other ordinances of the jurisdiction.

(b) Inspection Requests. It shall be the duty of the person doing the work authorized by a permit to notify the Building Official that such work is ready for inspection. The Building Official may require that every request for inspection be filed at least one working day before such inspection is desired.

It shall be the duty of the person requesting inspections required by this code to provide access to and means for inspection of such work.

(c) Operation of Electrical Equipment. The requirements of this section shall not be construed to prohibit the operation of any electrical system or equipment installed to replace existing equipment. The request for inspection of such equipment must have been filed with the Building Official not more than 48 hours after such replacement work is completed and before any portion of such electrical system is concealed by any permanent portion of the building.

(d) Other Inspections. In addition to the called inspections required by this code, the Building Official may make or require other inspections of any work to ascertain compliance with the provisions of this code and other laws which are enforced by the code enforcement agency.

(e) Reinspections.

(1) 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.

(2) This provision 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 reinspections.

(3) Reinspection fees may be assessed when the approved plans are not readily available to the inspector, for failure to provide access on the date for which inspection is requested, for not completing the corrective actions from original inspections, or for deviating from plans requiring the approval of the Building Official.

(4) To obtain a reinspection, the applicant shall file an application therefor in writing upon a form furnished for that purpose, and pay the reinspection fee as set by resolution of the Board of Supervisors.

(5) When reinspection fees have been assessed, no additional inspection of the work will be performed until the required fees have been paid.

26. Connection Approval.

(a) Energy Connections. An electrical system or equipment regulated by this code for which a permit is required shall not be connected to a source of energy or power until approved by the Building Official.

(b) Temporary Connections. The Building Official may authorize the temporary connection of the electrical system or equipment to the source of energy or power for the purpose of testing the equipment, or for use under a temporary Certificate of Occupancy.
