For some types of construction you are required to get special inspections. Special inspections are in addition to inspections performed by our inspectors. Your project reviewer determines which special inspection items are needed during review of your permit application. Required special inspections often include structural or geotechnical inspections.
The special inspection agency evaluates aspects of construction that are critical to structural safety, site stability, and environmental conditions. The special inspection agency also confirms that the work is built according to the plans we approved. All structural special inspectors must be certified by the Washington Association of Building Officials. Geotechnical special inspectors must be the Geotechnical Engineer of Record for the project, and they must be a licensed professional engineer in the state of Washington with at least 4 years of experience in a responsible geotechnical engineering position.
The project owner selects and pays the special inspection agency. (The contractor cannot pay for special inspections.) We charge a one-hour fee when we issue your permit to review reports and letters, address construction issues, and close out the special inspections. We charge and bill the project owner for additional time at our hourly rate if necessary.
