Building Inspection

All building permits will require inspections at various stages of construction. The Building Inspector will inspect construction relative to approved plans and the attached comments. If the project complies with plans and all code requirements the inspector will provide approval for the work completed. In the event that any corrections are needed, the inspector will provide a list of items to be completed. The contractor or property owner is required to request all inspections associated with an issued building permit.
