Decoding Disclosure: The Seller’s Responsibility Under the Minnesota Radon Awareness Act
In the Twin Cities real estate market, silence regarding indoor air quality is no longer an option. The Minnesota Radon Awareness Act shifted the burden of information onto the seller, transforming radon from a negotiable inspection item into a mandatory disclosure. Many sellers mistakenly believe that if they haven't tested, they have nothing to disclose, but the law requires communication of specific risks and any historical data associated with the property.
Compliance is not just about checking a box on a disclosure form; it is a risk mitigation strategy. For homeowners in the metro area, understanding the intersection of state law and local soil conditions is critical. This guide outlines the specific documents required by the MN Dept. of Health and how to handle testing during a home sale to ensure a clean title transfer.
Why Technical Compliance is Non-Negotiable
The law is designed to ensure buyers are informed of the health risks associated with radon gas before they are legally bound to a property.
- Professional Radon Testing creates a definitive paper trail regarding known conditions.
The Framework for a Compliant Sale
The disclosure process follows a sequence that must be completed before a purchase agreement is executed. Following these steps ensures the seller meets the requirements set forth in Sec. 144.496 MN Statutes.
1Distribute the Radon Warning Statement
The law requires a specific warning statement to be included in the disclosure. This text informs the buyer that the property may be exposed to dangerous levels of radon gas and that testing is recommended. This statement must be provided in writing to the buyer prior to the signing of the purchase agreement.
2Disclose Known Radon Concentrations
Sellers must provide any information regarding the most recent radon test results performed on the dwelling. If a test was conducted, the seller must disclose the level found, the date of the test, and the specific area of the home where the test was located. If no test has ever been performed, the seller must explicitly state that they have no knowledge of radon concentrations.
3Provide Descriptions of Mitigation Systems
If the property has an existing radon mitigation system, the seller must disclose its presence. This includes providing any available information regarding the system’s installation and current operational status.
4Share the MDH Health Guide
The seller is legally obligated to provide the buyer with a copy of the Minnesota Department of Health publication titled "Radon in Real Estate Transactions". This document explains the risks of radon and the importance of testing. Providing this ensures the buyer has been educated by the state’s primary health authority.
The Disclosure Gap in "Unknown" Status
Many sellers opt not to test their homes prior to listing, choosing instead to disclose that the radon status is "unknown." While this technically satisfies the letter of the law if no prior tests exist, it often triggers an inspection contingency. Because the metro area is known for radon presence, buyers often request a test.
If a buyer’s test reveals elevated levels, the seller then possesses knowledge of radon concentrations. Per the MN Dept. of Health, the law requires the disclosure of any knowledge the seller has regarding radon concentrations in the dwelling. Proactively conducting a professional test allows the seller to manage the disclosure process and address mitigation before the home hits the market. Minneapolis Radon Services can provide measurement services to document these levels.
How Minneapolis Radon Services helps
Navigating the requirements of a sale involves coordinating with inspectors, agents, and buyers within tight closing windows. Standard engagements typically begin with a test to provide a breakdown of radon levels. If levels exceed recommended safety thresholds, a scope of work is developed to include sump pit sealing, slab penetration closure, and the installation of an active soil depressurization system. Property owners should ensure that any testing results are delivered in a format that can be directly attached to the Minnesota disclosure forms.

Frequently asked questions
Does the law apply to new construction homes in Minnesota?
Yes, the Radon Awareness Act applies to residential property transfers, including new builds. While new homes in Minnesota are often built with passive radon systems under current building codes, the seller must still provide the mandatory warning statement and disclose any testing performed.
Can a buyer waive their right to radon disclosure?
No, the disclosure requirements are a statutory mandate. While a buyer can choose not to perform their own testing as part of their inspection contingency, the seller is still legally required to provide the warning statement, the MDH guide, and any known testing history.
Is a DIY charcoal canister test sufficient for disclosure?
While the law requires the disclosure of any "known" records, real estate transactions often rely on professional-grade continuous monitors.
What is the definition of residential real property under this act?
According to MN Stat. 144.496 Subd. 2, residential real property means any interest in residential real property. This includes dwellings regardless of the number of family units, though standard real estate practices frequently focus on 1-4 unit dwellings.
What if radon is found during the inspection?
When radon is discovered during an inspection, the buyer and seller typically negotiate repairs. The seller may choose to install a mitigation system to address the levels, which then becomes a permanent part of the home's features that must be disclosed in future transfers.
