An application missing any items will be deemed incomplete and the plan check will not be scheduled until all the items indicated are received by Building Services. This may affect application fees and codes since the operative date of application will be the date on which a complete application is received.

CHECK OUR PLAN REVIEW GUIDELINES FOR MORE DETAILS ON THE PLAN CHECK PROCESS. The guideline, while not all-inclusive, is intended to help you prepare residential plans that are essentially "complete".
