Why Minnesota runs below the US average

Radon mitigation pricing in Minnesota reflects three regional factors: licensed HVAC / specialty trade wages (BLS), EPA Zone density (Zone-1 states have mature mitigator markets and competitive pricing), and state-specific permitting / disclosure requirements. The 0.98× factor is calibrated from 2025 AARST + HomeAdvisor regional rate data.

Local note · Minnesota: EPA Zone 1 statewide — Minnesota has among the highest indoor radon levels. Strong MDH radon program + mandatory disclosure law. Twin Cities mitigator density very high.
