Radon Mitigation in Minneapolis, Minnesota
Minneapolis housing is famous for its 1920s bungalows, and their basements are where the city's radon story lives. Hennepin County is rated Zone 1 on the EPA Map of Radon Zones, the highest radon potential category, and the Minnesota Department of Health reports 2 in 5 tested homes statewide at levels posing a significant health risk.
MDH has also shown that metro mitigation rates lag in lower-value and rental housing, meaning plenty of high-radon Minneapolis homes are still unfixed. We connect Minneapolis homeowners with independent, MDH-licensed mitigation contractors for free written quotes.

Radon Levels Around Minneapolis
Zone 1
the EPA radon zone for Hennepin County, predicting average indoor levels above 4 pCi/L
Beyond the zone rating, a 2020 MDH analysis of metro data found mitigation rates vary sharply with neighborhood income, home value, and housing type: the homes least likely to be fixed are not the ones least likely to have radon. County-by-county results live on the MDH data portal; testing is the step that closes the gap.
Glacial Drift Over River Bedrock
Minneapolis sits on glacial till and outwash, the deposits the Minnesota Geological Survey maps across the metro, resting over the sedimentary bedrock the Mississippi cut its gorge through. MDH attributes radon to uranium decaying naturally in rocks and soil, and the glacial blanket under the city carries that source everywhere the streetcar grid goes. Neighborhood does not predict your number; construction details and luck do, which is why MDH pushes testing over guessing.

The classic Minneapolis house is a 1900 to 1940 bungalow or foursquare on a limestone-block or early concrete basement, with floor drains and a century of settling cracks, all of it soil-gas entry per the MDH list. Standard sub-slab systems handle these homes well, with sealing as the labor-intensive part. Southwest and Northeast infill, condo conversions, and post-2009 construction with passive rough-ins round out the mix; ground-contact units are the ones radon reaches.
Local Radon Contacts and Test Kits
Hennepin County and the city health department field radon questions for Minneapolis residents; the MDH Local Radon Contacts directory lists the current programs and kit sources for the metro.
What Does Radon Mitigation Cost in Minneapolis?
The Minnesota Department of Health reports a typical installed range of $1,500 to $3,000 statewide. Foundation type, home size, and routing decide where a Minneapolis home lands. The cost guide breaks down every factor with primary-source numbers.
Verify Your Contractor's Minnesota Radon License
Before you hire anyone for radon work in Minneapolis, 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?
Minneapolis Radon Questions
Do old Minneapolis bungalows have worse radon?
Age does not raise the radon in the soil, but pre-war basements offer more entry routes: limestone-block walls, floor drains, and slab cracks are all on the MDH entry list. Hennepin County is EPA Zone 1 regardless of housing era, so MDH guidance is the same for a 1915 bungalow and a 2015 townhome: test.
Which Minneapolis homes go unmitigated most often?
A 2020 MDH metro analysis found mitigation rates track neighborhood income and home values, with lower-value and rental housing least likely to be tested or fixed. Exposure does not follow the same lines, so renters and entry-level buyers have the most to gain from a cheap test.
I am selling a Minneapolis house. Will radon come up?
Almost certainly. Minnesota's Radon Awareness Act requires written disclosure of radon records before a purchase agreement, and metro buyers test during inspections as a matter of course. A pre-listing test, and a tagged mitigation system if needed, keeps the issue out of your negotiation.
How much does radon mitigation cost in Minneapolis?
The Minnesota Department of Health reports a typical installed range of $1,500 to $3,000 statewide. Finished basements and aesthetic routing on older homes are the usual Minneapolis variables. The written quote from the MDH-licensed contractor you are matched with is free.
