The largest untested category in Vermillion is rental housing, and it is untested for a structural reason: South Dakota does not require landlords to disclose radon levels to tenants and does not require testing at all. Nothing forces the question, so mostly nobody asks it.
What we see in Vermillion
Older housing around the University of South Dakota campus converted to student rentals is where this concentrates. Owner-occupied property toward Cotton Park and out along Highway 50 gets tested at roughly the rate the rest of the state does, which is to say when somebody is buying or selling.
Practical notes for Vermillion homeowners
For landlords: testing a Vermillion rental is voluntary, cheap, and increasingly something tenants and parents ask about. A recent result in the listing is a differentiator in a market where nobody else has one.
Radon Testing in Vermillion: the technical part
Student rentals are difficult to test properly for a mundane reason: closed-house conditions are almost impossible to maintain in a house with five tenants coming and going. Doors open constantly, windows get opened regardless of instructions, and a 48-hour window rarely passes cleanly. The result is a reading biased low, which is the direction that hides a problem rather than inventing one.
What the job looks like in Vermillion
We test rentals between tenancies wherever possible, which in Vermillion means the gaps around the academic calendar. Where that is not possible, a 90-day alpha track through occupied term time gives a fairer picture than a short test that keeps getting ventilated. Landlords with several properties usually get them done in one pass.
How Vermillion houses are built
A university town means landlords, and South Dakota does not require landlords to disclose radon levels to tenants. Older houses near campus converted to student rentals frequently have never been tested at all.
Vermillion radon questions
When is the best time to test a student rental?
Between tenancies, when the building can be kept closed. Failing that, a long-term device through the heating season rides out the door-opening problem.
Do I have to tell tenants the result?
South Dakota does not require it. Plenty of landlords do it anyway, and increasingly it is something prospective tenants and their parents ask about directly.
