Radon for Real Estate Transactions in Colorado Springs
Radon shows up in most Colorado Springs home sales for two reasons. The numbers: El Paso County Public Health reports over 40 percent of county homes tested from 2005 to 2023 exceeded the EPA action level. And the law: under Senate Bill 23-206, every Colorado residential sale contract now carries a radon disclosure, and sellers must share what they know. We connect buyers, sellers, and their agents with independent, Colorado-licensed radon professionals who work on contract deadlines, with free quotes and no obligation. If a test already came back high and a deadline is ticking, our guide on radon high during a Colorado Springs closing walks through the next moves step by step.
What Colorado law now requires in a sale
Senate Bill 23-206, effective August 7, 2023, requires each contract of sale for residential real property to contain a clearly legible radon disclosure recommending that buyers have an indoor radon test performed, and requires sellers to disclose their knowledge of the property's radon history, including past test results and any mitigation system. The Colorado Division of Real Estate updated its Commission-approved contract forms to carry the new language, per its broker practice advisory. In practice: radon is no longer an optional conversation in a Colorado closing, it is on the paperwork.
Four ways radon enters a transaction
Buying a home
Order a radon test during your inspection window. If the result comes back at or above 4 pCi/L, you can negotiate mitigation with the seller before your objection deadline instead of discovering the problem after closing.
Selling a home
Colorado sale contracts now include a radon disclosure, and you must share what you know: past test results and any mitigation system. Testing before you list, and mitigating if needed, turns radon from a negotiation risk into a selling point.
Under deadline pressure
Inspection objection deadlines wait for no one. Licensed contractors who work transactions run 48-hour continuous monitor tests and can often schedule mitigation installs inside the resolution window, with a retest to document the fix.
Military PCS moves
Fort Carson, Peterson SFB, Schriever SFB, and the Air Force Academy keep Colorado Springs real estate moving on orders, not on convenience. Radon fits inside a PCS timeline when the testing and mitigation are scheduled like the rest of the move.
The transaction timeline, handled
- 1
Request lands with a licensed contractor who works real estate deadlines and confirms scheduling the same business day where possible.
- 2
A licensed measurement professional sets a continuous monitor for 48 hours under closed-house conditions and delivers a written, time-stamped report.
- 3
If the result is at or above 4 pCi/L, the mitigation quote follows fast so the parties can negotiate with a real number, not a guess.
- 4
Installation is scheduled inside the resolution window. Most single-family systems go in during a single visit.
- 5
A post-mitigation retest documents the reduced level, and the paperwork travels with the deal file for the disclosure record.
PCS orders and radon: the military reality
Colorado Springs real estate runs on the military calendar. Fort Carson, Peterson Space Force Base, Schriever Space Force Base, and the Air Force Academy generate a constant cycle of PCS arrivals and departures, and those transactions compress everything, including radon, into weeks instead of months. Buying from another duty station means the radon test happens while you are not in the state; selling on orders means a surprise result cannot be allowed to stall closing. The same licensed-contractor network handles both, and our military PCS radon guide lays out the sequence step by step. Areas around the installations, like Security-Widefield near Fort Carson and Cimarron Hills by Peterson SFB, carry the same El Paso County radon odds as the rest of the region.
