Norwalk, CA Building Safety: Building Inspections (2026)

090 requires that construction under a permit remain accessible and exposed for inspection until approved, and puts the duty on the permit applicant to keep it that way; the City is not liable for costs of exposing work for inspection. 10 once notified the work is ready. In sequence, the code calls for a footing and foundation inspection after excavation, reinforcing steel and forms are in place; a concrete slab inspection before concrete is poured over in-slab steel and utilities; an under-floor inspection before sub-floor sheathing; a floor and roof sheathing inspection after nailing and shear connections; a frame inspection once roofing, framing, fire blocking and rough electrical, plumbing and HVAC are in and approved; energy efficiency inspections for insulation, fenestration and HVAC/water-heating values; fire-resistant penetration checks before concealment; a lath and gypsum board inspection before plastering or taping; weather-exposed balcony waterproofing checks; and special inspections under Section 1704 where required.

11 makes the final inspection mandatory after all permitted work is complete, and a permit is not valid and complete without it. 5 requires the permit holder to notify the Building Official when each stage is ready and to provide access for it.
