R108.6 Work commencing before permit issuance. Any person who commences any work requiring a permit on a building, structure, electrical, gas, mechanical or plumbing system before obtaining the necessary permits shall be subject to a fee established by the building official that shall be in addition to the required permit fees. An investigation fee, in addition to the permit fee, shall be collected whether or not a permit is then or subsequently issued. The investigation fee shall be at least equal to and not to exceed five times the permit fee required by this code.

California Residential Code Chapter 1 Section R108.7 is added as follows:

R108.7 Re-inspection. A re-inspection fee may be assessed for each inspection or re-inspection 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 re-inspection 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 re-inspection.

Re-inspection fees may be assessed when the inspection record card is not posted or otherwise 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 inspection is requested, or for deviating from plans requiring the approval of the building official. To obtain a re-inspection, the applicant shall file an application therefor in writing on a form furnished for that purpose and pay the re-inspection fee in accordance with Table 1 or as set forth in the fee schedule adopted by the jurisdiction. In instances where re-inspection fees have been assessed, no additional inspection of the work will be performed until the required fees have been paid.

California Residential Code Chapter 1 Section R108.8 is added as follows:

R108.8 Violation penalties. 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 CMC Chapter 1.08. An investigation fee, in addition to the permit fee, shall be collected whether or not a permit is then or subsequently issued. The investigation fee shall be at least equal to the minimum investigation fee set forth in the adopted fee schedule and shall not exceed five times the permit fee required by this code.
