Radon and Well Disclosure: What Edina Sellers Must Provide

Selling your home in Edina? Buyers will expect clear answers about radon and any wells on the property. Minnesota law sets specific disclosures you must give before anyone signs a purchase agreement. In this guide, you will learn exactly what to provide, when to provide it, and how to prepare so your sale moves forward without surprises. Let’s dive in.

What Minnesota law requires

Radon disclosure: what and when

Minnesota’s Radon Awareness Act requires you to disclose your knowledge about radon in the home before a buyer signs a purchase agreement. You must state whether any radon test has been done, share the most recent test report, describe any mitigation or remediation, provide details for any mitigation system, and include the statutory radon warning statement. You must also give buyers a copy of the Minnesota Department of Health (MDH) publication titled “Radon in Real Estate Transactions.” See the statutory requirements in Minnesota Statutes chapter 144 under the radon sections at the Minnesota Revisor site.

• Reference: Minnesota radon disclosure requirements and timing are outlined in the Radon Awareness Act at the Minnesota Revisor of Statutes: Minn. Stat. ch. 144 (radon and licensing).
• MDH guidance: testing and mitigation are not mandatory for every sale, but MDH strongly recommends testing in real estate transactions. Learn more at MDH’s Radon in Real Estate page.

Well disclosure: what and when

Minnesota law requires you to disclose the location and status of all known wells on the property before signing a purchase agreement. You must either sign a statement that you do not know of any wells or provide a disclosure that identifies each known well with a sketch or map and whether the well is in use, not in use, or sealed. At closing, the information is transferred to a well disclosure certificate and a $50 fee is collected by the county.

• Reference: well disclosure duties and the closing certificate are described in Minn. Stat. § 103I.235. MDH guidance and checklists are available at MDH’s well disclosure page.

Waivers do not remove these duties

Even if you and the buyer agree to waive the general Minnesota seller disclosure form, you still must comply with radon and well disclosure laws. The waiver statute does not override obligations created by other laws. See Minn. Stat. § 513.60.

Why this matters in Edina

MDH reports that Minnesota’s average indoor radon level is around 4.2 to 4.5 pCi/L, which is higher than the U.S. average. Hennepin County, which includes Edina, has elevated radon potential, so buyers often request transaction testing or ask about mitigation. See MDH’s statewide radon context in this MDH press release. The EPA recommends mitigation at 4.0 pCi/L; learn more about the action level from the EPA’s radon guidance.

Step-by-step checklist for Edina sellers

1. Before you list or accept an offer

• Radon: prepare a written disclosure stating whether testing has been done, attach the most recent radon report, describe any mitigation, and include the required radon warning statement. Provide the MDH “Radon in Real Estate Transactions” pamphlet. See the radon statute at the Minnesota Revisor.
• Wells: determine if there are any wells. If so, prepare a sketch or map showing each well’s location and mark the status as in use, not in use, or sealed. If you do not know of any wells, you will sign the deed statement required by statute. See Minn. Stat. § 103I.235.

2. If you have radon test results

• Provide the actual report to the buyer along with details about any mitigation system, including installer documentation and the MDH system tag if installed on or after January 1, 2019. Statutory details appear in Minn. Stat. ch. 144.

3. If you do not have radon test results

• You are not required by law to test before selling, but MDH strongly recommends testing in real estate transactions. Consider a pre-listing test to reduce delays. Use a licensed radon measurement professional as recommended on MDH’s Radon in Real Estate page.

4. If a well provides potable water

• Confirm whether the well is in use and ensure your map and status are accurate. The well disclosure statute was amended in 2025, so confirm any new requirements or effective dates on the Minnesota Revisor’s § 103I.235 page or with MDH resources.

5. What to hand the buyer

• Radon disclosure form plus the MDH pamphlet.
• Any radon test reports and mitigation documentation.
• Well disclosure statement and sketch or map. The well disclosure certificate will be handled at closing.

6. Use licensed professionals when needed

• Anyone testing or mitigating radon for a property they do not own must be licensed. MDH recommends licensed professionals for transaction testing and mitigation. See guidance in Minn. Stat. ch. 144 and MDH’s radon resources.

Fees, timing, and closing day

• Timing: both radon and well disclosures must be given before the buyer signs a purchase agreement.
• Closing paperwork: the well disclosure certificate is completed and submitted at closing, based on the information you provided earlier.
• Fee: the county collects a $50 fee when it receives the completed well disclosure certificate. The county keeps a portion and forwards the rest to MDH for retention.

Avoid pitfalls and liability

• Radon liability: if you fail to make the required radon disclosure and knew material facts about radon concentrations, a buyer can bring a civil action. The action must start within two years after closing. See Minn. Stat. ch. 144.
• Well liability: unless otherwise agreed in writing before closing, if you knew or had reason to know of a well and did not disclose it, you can be liable for the cost to seal the well and reasonable attorney fees. A buyer has up to six years after closing to bring a claim. See Minn. Stat. § 103I.235.
