--- title: "Septic Inspectors & Radon Pros in Olmsted County, MN: 17 Licensed | MN Home Sale Pros" description: "3 MPCA-licensed SSTS inspectors and 14 MDH-licensed radon pros based in Olmsted County, Minnesota, for home sales." canonical: https://mnhomesalepros.com/county/olmsted/ --- [Home](https://mnhomesalepros.com/) › [Counties](https://mnhomesalepros.com/counties/) › Olmsted County # Septic inspectors and radon pros in Olmsted County, MN 3 MPCA-licensed SSTS inspector businesses and 14 MDH-licensed radon businesses list an address in Olmsted County. 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)). Ask the county or city SSTS office whether a transfer inspection applies. Inspections must be done by an MPCA-licensed SSTS inspector business. ## SSTS (septic) inspectors (3) ✔ MPCA SSTS licensed InspectorIntermediate InspectorAdvanced Inspector ### G G G Inc. 14070 Hwy 52
