Many work across counties, and most radon pros list a statewide service area. Minnesota has no single statewide septic-at-sale rule, but many counties and cities require an SSTS compliance inspection at property transfer by local ordinance ([MPCA local SSTS programs](https://www.pca.state.mn.us/business-with-us/local-septic-system-programs)).
