A building inspection is performed by the municipal building department to verify code-minimum compliance — verifying that the work meets the IRC, IBC, or IECC, but not evaluating craftsman quality or project-specific specifications beyond code requirements. A contractor’s QA inspection evaluates both code compliance and craftsman quality against the project’s specific workmanship standards — which typically exceed code minimums. A building inspector verifying framing confirms the shear wall nailing pattern and structural spans meet code; they will not assess whether the framing is plumb to a craftsman standard, whether all backing for finish work is in place, or whether exposed framing quality matches the design intent. Construction QA and building department inspections serve complementary roles: QA catches what the building department won’t assess; the building department provides independent code compliance verification. Both are required; neither is a substitute for the other.
