A marketing service connecting Minnesota homeowners with licensed radon
mitigation contractors. Compass Camper LLC is not a licensed contractor and
does not perform radon mitigation work.
Radon shows up in almost every Minnesota home sale, because state law
puts it there. The Minnesota Radon Awareness Act,
Minnesota Statutes section 144.496, requires sellers to disclose radon information in writing before a
purchase agreement is signed, and buyers routinely test during the
inspection window. When the clock is running, we connect buyers and
sellers anywhere in Minnesota with independent, MDH-licensed contractors
who quote and schedule on transaction timelines.
What Minnesota Sellers Must Disclose
For sales beginning January 1, 2014, section 144.496 requires written
disclosure to the buyer of:
Whether a radon test or tests have occurred on the property
The most current records and reports pertaining to radon concentrations in the dwelling
A description of any radon concentrations, mitigation, or remediation
The MDH publication Radon in Real Estate Transactions, delivered to the buyer
The required publication is available from MDH:
Radon in Real Estate Transactions. MDH's
radon in real estate page explains the law in plain language. A seller who knows of radon issues
and fails to disclose can be liable to the buyer under the statute.
Buying on a Deadline
Inspection contingencies in Minnesota purchase agreements are short. The
workable sequence: order a licensed measurement during the inspection
window, and if the result comes back at or above the EPA action level of
4 pCi/L, get a written mitigation quote before the contingency expires so
you can negotiate the fix or a credit with real numbers. The
Minnesota Department of Health reports typical installed costs of $1,500 to $3,000, which is small
against the purchase but worth getting in writing. Our
Minnesota cost guide shows what drives the number.
Selling Without a Mid-Transaction Surprise
Sellers who test before listing decide the timeline themselves. If the
level is fine, the result becomes part of a clean disclosure. If it is
elevated, a system installed by a licensed contractor, tagged under the
MDH program, converts a negotiation risk into a selling point. Buyers in
high-test markets like Rochester and the Twin Cities know to ask; see
our Minneapolis
and St. Paul pages
for how radon plays in those markets.
Verify Your Contractor's Minnesota Radon License
Before you hire anyone for radon work in Minnesota, check their license. The Minnesota Radon Licensing Act,
Minnesota Statutes section 144.4961, requires anyone who performs radon testing, mitigation, or
laboratory analysis for compensation to be licensed by the
Minnesota Department of Health, and every mitigation system installed under the law must carry
an MDH system tag. A licensed professional expects the question.
Three things to ask before you sign:
Can I see your current MDH radon license, and is the company licensed too?
Will the installed system carry the MDH system tag required under the licensing law?
Will I get a written, itemized estimate and a follow-up radon test that confirms the system works?
Does Minnesota require radon disclosure when selling a home?
Yes. The Minnesota Radon Awareness Act, Minnesota Statutes section 144.496, applies to residential sales beginning January 1, 2014. Before signing a purchase agreement, the seller must disclose in writing what they know about radon in the home, including test records and any mitigation, and must give the buyer the MDH publication Radon in Real Estate Transactions.
Does Minnesota law require a radon test before a home is sold?
No. The Radon Awareness Act requires disclosure of what the seller knows, not a test. That is exactly why buyers routinely add radon testing to the inspection contingency: the disclosure only covers existing records, and a licensed measurement result is the way to know the actual number before closing.
The radon test came back high during my purchase. Now what?
This is common in Minnesota, where MDH data shows 2 in 5 tested homes have levels posing a significant health risk. Buyers typically negotiate for the seller to install a mitigation system before closing or credit the cost at closing. A licensed contractor can usually provide a written quote fast enough to use in negotiations, and installation itself is normally a one-day job.
I am selling. Should I test or mitigate before listing?
Testing before listing puts you in control: you learn the number first, can fix it on your own schedule, and the MDH system tag on a professionally installed system becomes a straightforward part of your disclosure instead of a mid-transaction surprise. Whatever records you create must then be disclosed under section 144.496.
