Norman, OK Building Safety: Building Inspections (2026)

Norman adopted the 2018 International Residential Code by reference in NCC 6-209, with local amendments that spell out the inspection sequence for one- and two-family homes. 4, the frame inspection cannot happen until the roof, framing, firestopping, draftstopping and bracing are all in place, and only after the plumbing, mechanical and electrical rough-in inspections have already been approved. 2 pushes the sequence one step further: the insulation inspection has to wait until framing, mechanical, electrical and plumbing rough-in are all approved, and it must happen before any wallboard material goes up, a term the code defines broadly to include lath, plaster, gypsum wallboard, wood paneling and sheet metal.

1 adds one more checkpoint, requiring elevation documentation to reach the Floodplain Administrator before the final inspection can be scheduled. 3 puts the scheduling burden on the builder: the permit holder or their agent has to notify the Building Official when work is ready, and must provide safe access to the site so the inspection can actually happen. Inspections themselves are carried out by the Development Services Division under NCC 6-103 and 6-104, which requires a permit before any covered work begins. 1 cannot issue until the Building Official has signed off on the full inspection chain, so getting the order wrong risks a costly rip-out of finished walls to expose rough-in work for re-inspection.
