Landlord and Rental Radon in Colorado
Owning rental property in Colorado Springs now comes with radon
homework. Under
Senate Bill 23-206, effective August 7, 2023, Colorado landlords must disclose radon
information before every lease signing, and tenants gained real remedies
when elevated radon goes unaddressed. In El Paso County the underlying
risk is not theoretical:
El Paso County Public Health reports over 40 percent of homes tested from 2005 to 2023 exceeded the
EPA action level. We connect rental owners with independent,
Colorado-licensed radon professionals who produce the testing and
mitigation paperwork the law now assumes you have.
What the law asks of rental owners
Disclose before every lease signing
Before a tenant signs, Colorado landlords must provide a radon warning statement recommending an indoor radon test, plus what the landlord knows: whether the property has been tested, the most current radon records, and whether a mitigation system is installed.
Respond when a test comes back high
The law gives tenants leverage when radon at or above 4 pCi/L goes unaddressed. A landlord who receives professional notice of an elevated level and does not mitigate within 180 days risks the tenant voiding the lease and vacating.
Keep records that travel
Test reports and mitigation documentation feed both the lease disclosure and, later, the sale disclosure that SB23-206 added to every Colorado residential contract. One licensed test produces paperwork you will reuse.
Think in units, not just buildings
Radon enters from the soil, so ground-contact units carry the exposure: garden levels, basements, and first floors on slabs. A licensed measurement professional plans unit sampling so the results actually represent the building.
This page summarizes the statute in plain language and is not legal
advice. The bill text at
leg.colorado.gov is the authoritative source, and a Colorado attorney can apply it to
your specific leases.
A compliance sequence that actually finishes
1
Inventory your ground-contact units: basements, garden levels, and slab-on-grade first floors are where radon concentrates.
2
Test with a licensed measurement professional so the results are defensible in a disclosure or a dispute.
3
Mitigate any unit at or above 4 pCi/L with a licensed mitigation contractor. Most residential systems install in a single visit.
4
Retest after installation to document the reduced level.
5
Attach the records to your lease packets, and keep them for the sale disclosure Colorado now requires in every residential contract.
What mitigation costs a rental owner
The variables are the same as any home: foundation type, number of
suction points, vent routing, and fan sizing, multiplied across however
many ground-contact units need treatment. Licensed contractors quote in
writing before any work, so you can budget per building instead of
guessing. What Colorado state sources publish about typical single-home
ranges is collected in our
cost guide.
Since July 1, 2022, Colorado law has required anyone performing radon
measurement or radon mitigation services for hire to hold a state
license through the
Department of Regulatory Agencies' Division of Professions and Occupations. The requirement was created by
House Bill 21-1195. Before you sign anything, check the license and ask these three
questions. A licensed contractor will welcome all of them.
1 May I see your current Colorado radon license number?
2 Is the person doing the work the licensed individual?
3 Will you retest after installation to confirm the reading dropped?
What it costs, and what happens after you send the form
What does radon mitigation cost in the Colorado Springs area?
CDPHE publishes a typical mitigation range of approximately $1,300 to
$3,000 for an existing single-family home, as of July 2026, but that is not
this page's number. Testing is far less, and a rental or multi-unit situation is priced
on its own, so the licensed contractor who looks at the property is the honest source of
that figure.
Either way it is a range to plan against, not a quote and not our price. The
cost guide
breaks it down.
How fast will someone get back to me?
Calls and form submissions reach Compass Camper LLC directly. We read the request and pass it
to an independent state-licensed local radon professional, usually within about an hour during
the day. They then contact you to look at the property and quote the work on their own
schedule.
Only the independent state-licensed contractor you are matched with can price your actual
property. Compass Camper LLC does not perform radon work and does not quote it.
Landlord and Rental Radon Questions
What exactly does Colorado require landlords to disclose about radon?
Under Senate Bill 23-206, effective August 7, 2023, a landlord must give prospective tenants, before the lease is signed, a warning statement recommending an indoor radon test, along with whether the property has been tested for radon, the most current records of radon concentrations, and whether a radon mitigation system has been installed.
Can a tenant really break the lease over radon?
The law creates that remedy in defined situations: when a landlord fails to make the required disclosures, or when radon at or above 4 picocuries per liter is not mitigated within 180 days after the landlord receives professional notice of the elevated level. On or after January 1, 2026, the lease-voiding remedy does not apply to leases of one year or less. The bill text at leg.colorado.gov is the authoritative source.
Do I have to test my rental property?
The disclosure duty applies either way: if you have not tested, you disclose that. But an untested rental in El Paso County is a coin flip you have not looked at, since over 40 percent of homes tested in the county from 2005 to 2023 exceeded the action level, per El Paso County Public Health. Testing once, and mitigating if needed, converts an open question into documented compliance.
Who pays for mitigation in a rental, landlord or tenant?
The property owner typically contracts and pays for mitigation, since the system is a permanent improvement to the building. The 180-day mitigation window in SB23-206 runs against the landlord. The contractor you are matched with quotes the owner directly in writing.
How does mitigation work in a multifamily building?
The same active soil depressurization principle as a single-family home, scaled to the foundation layout. Contractors evaluate which ground-contact units and common foundations need suction points, and a post-installation retest documents the result for your records and future disclosures.
