Reinspection 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 deviation from plans requiring the approval of the Building Official. To obtain a reinspection, the applicant shall file an application therefore in writing upon a form furnished for that purpose and pay the reinspection fee in accordance with a fee schedule adopted by this jurisdiction.

The Building Official may require that every request for inspection be filed at least one working day before such inspection is desired. Such request may be requested in writing or by telephone at the option of the Building Official. It shall be the duty of the person requesting any inspections required by either this Code or the technical codes to provide access to and means for inspection of the work.
