What will make a house not pass an inspection?

A house may not pass inspection when major structural damage, foundation movement, roof leaks, electrical hazards, plumbing failures, mold growth, pest infestations, or serious water damage are found. Unsafe wiring, broken HVAC systems, poor drainage, and evidence of rot also raise concerns. Missing smoke detectors, railings, or other safety features can affect results. Cosmetic issues rarely matter, but significant health or safety hazards do. Failing inspection does not block the sale; instead, it typically leads to negotiations, repairs, or price adjustments. Preparing early and addressing maintenance issues helps avoid negative surprises during inspection day.
