All of North Dakota and Clay County, Minnesota, are in EPA radon Zone 1. But radon still varies from house to house, so every home needs its own test.
Fargo
Fargo has everything from early-1900s homes with old basements near downtown to brand-new houses on the south side. Older basements often have more cracks and openings; newer homes are tighter and can trap radon. Either way, start with a test in the basement.
West Fargo
West Fargo has grown fast, with many newer homes. Some have passive radon pipes installed by the builder. If yours does and your test is still high, adding a fan is often the simplest fix.
Moorhead
Across the river in Clay County, Minnesota, Moorhead homeowners need a radon professional licensed by the Minnesota Department of Health. If you're selling, Minnesota's Radon Awareness Act requires you to disclose what you know about radon in the home.
Horace
South of Fargo, Horace has many new subdivisions. New construction is not immune to radon, so test once you've moved in and the house has been closed up for a season.
Casselton
About 20 miles west of Fargo along I-94, Casselton has a mix of older town homes and rural properties. Farmhouses with additions sometimes combine a basement with a crawl space, which can affect the system design.
Dilworth
East of Moorhead in Clay County, Dilworth is on the Minnesota side, so mitigation must be done by an MDH-licensed professional, and the system will get an MDH tag.
