What Minneapolis agents can say about radon without guessing

This is not legal advice and it is not your brokerage’s form. The Minnesota Radon Awareness Act has required disclosure and education in residential sales since January 1, 2014. Before the purchase agreement is signed, the seller discloses known radon information in writing and gives the buyer MDH’s brochure. Testing is not mandatory. Mitigation is not mandatory. The buyer decides what level they will accept, and the parties negotiate who pays.

MDH wants the transaction test done by a licensed measurement professional, for at least 48 hours, with an approved continuous monitor or another approved option when time is short. A seller’s old charcoal kit from a basement closet in July is context. It is not automatically the test your buyer should rely on. Ask for the report, the dates, and the license if a pro ran it.

If a system is already in, look for the MDH tag on the pipe for work done on or after September 1, 2020, and ask for a post-mitigation test. MDH says a quality system often brings the annual average under 2.0 pCi/L. That is a goal the department states, not a promise about the house you are standing in. Retest about every two years after a system is installed.

Cost talk should stay sourced. MDH’s brochure says about $1,500 to $3,000. Hennepin County publishes a different range, about $500 to $2,500 with an average near $1,800. Tell clients both are public figures and the bid has to come from an MDH-licensed mitigator. National certification is not the Minnesota license.

Do not tell a buyer that “the Twin Cities are all Zone 1.” Minneapolis is in Hennepin County, which is Zone 1. Anoka is Zone 2. The house still needs a test either way. American Radon Systems is a Chicagoland installer. It is not a Twin Cities contractor. Point people at MDH’s provider list.

The public page to text a client is the guide home, not a cropped heatmap.
