First, the approved plans and building permit must be kept on the jobsite and be available to representatives of the Building Inspection Division at all times while the work is in progress and until final inspection. Inspections, as appropriate for the work being undertaken, will proceed in the following sequence: Footing – After the trench for the footing or for the basement has been excavated and forms are set, but before the footing is poured. Waterproofing – If waterproofing is required because the foundation will enclose habitable space, either now or in the future. Basement floor, slab-on-grade and crawlspace – Just prior to pouring concrete or setting floor joints. Under-slab inspections, as appropriate for foundation drains, plumbing, electrical and HVAC must be completed before the floor/slab/crawlspace inspection can be conducted. Framing – Prior to installation of insulation, and following rough-in plumbing, electrical and HVAC inspections. Energy Conservation – After insulation in walls, crawlspaces and roof/ceiling, but prior to any interior finish installation. Fire Resistance – If a fire resistance rating is required for all or part of a building, an inspection must be made prior to the spackling and taping of joints. Other inspections may be needed in regard to other life safety components of a building. Final – Before the issuance of a Certificate of Use and Occupancy, a final inspection must be successfully completed. Other inspections that will precede the final inspection may include plumbing, electrical, HVAC and fire prevention.
