How do home inspections differ between Minnesota and Iowa?

The inspection itself is nearly identical in both states: a visual, top-to-bottom evaluation of roof, structure, foundation, electrical, plumbing, HVAC, insulation, and built-in appliances, performed to InterNACHI standards with thermal imaging available as an add-on and a photo-documented report delivered within 24 hours. What differs is the surrounding context. Minnesota has municipal Truth in Sale of Housing programs, most notably in Saint Paul and Minneapolis, that require a city-mandated evaluation before listing; no Iowa law requires a home inspection before a sale (the one mandatory time-of-transfer inspection covers private septic systems), so a private buyer's inspection is the only close look most Iowa homes ever get. Radon priorities also shift: both states are high-risk, but Iowa has the largest percentage of homes above the EPA radon action level of any state, per Iowa HHS, so we treat radon testing as close to essential on Iowa transactions, and Iowa law requires sellers to disclose known radon results. Regionally, the defects change too. Minnesota work leans toward ice dams, deep-frost foundation movement, and pre-war Twin Cities housing stock; central Iowa work leans toward the heavy, poorly drained glacial till of the Des Moines Lobe, wet basements, sump pump dependence, and storm-damaged roofs from hail and the 2020 derecho. Same inspector, same rigor, different local knowledge.
