Radon doesn’t care whether a building is a house, a daycare, a warehouse, or a forty-unit apartment complex. What changes with a commercial building is the scale of the testing, the standards that apply, and how much is riding on the result — because the people breathing the air are your employees, your tenants, or somebody else’s children.
We connect building owners across Bowling Green and Warren County with certified professionals who test and mitigate commercial buildings, and who rough in radon control for new construction before the slab goes down, when it costs a fraction of what the same protection costs as a retrofit.
Houses follow one protocol. Multifamily, school, commercial, and mixed-use buildings follow another — ANSI/AARST MA-MFLB-2023, the consensus standard the EPA references for measurement in those buildings. It isn’t a longer version of a house test. It governs how many detectors are deployed and where, which spaces count as frequently occupied, how ground-contact areas are handled, and how results are documented.
Mitigation in those same buildings follows ANSI/AARST SGM-MFLB-2023. Larger footprints mean multiple suction fields, HVAC interactions a house never has, and pressure relationships you have to measure rather than assume.
If a company quotes a 30,000-square-foot building the way they quote a ranch house, that is the tell.
Schools and daycares. Children spend more waking hours in these buildings than anywhere except home, and they breathe more air relative to body weight than adults do. Testing is where every conversation about it starts.
Offices, retail, and warehouses. Ground-contact space is ground-contact space. Slab cracks, utility penetrations, floor drains, and elevator pits are all entry points, and a large slab has more of them.
Multifamily and apartment buildings. Ground-floor units carry most of the exposure. For properties in Kentucky Housing Corporation programs, radon testing is also a compliance question, not only a health one.
Mixed-use. Residential above, commercial below — one building, two sets of expectations, and the pressure relationship between them is exactly where radon problems hide.
The cheapest radon system anyone ever installs is the one that goes in before the concrete.
A rough-in during construction is aggregate, membrane, a sealed riser, and a labeled cap — materials measured in hundreds of dollars and a few hours of trade time. The identical protection added to a finished building means core drilling, exterior pipe runs, and working around finished surfaces somebody already paid for.
For one- and two-family dwellings and townhouses, the applicable standards are ANSI/AARST CCAH-2020 and ANSI/AARST RRNC-2020. For multifamily, schools, and commercial buildings, it is ANSI/AARST CC-1000-2018, “Soil Gas Control Systems in New Construction.”
A passive rough-in relies on stack effect alone, and in some buildings that is enough to stay under 4.0 pCi/L. Over Warren County karst, often it is not. The value of the rough-in is that activating it later is a one-hour fan installation instead of a project. Either way the building gets tested after occupancy, because a system nobody verified is not a result.
1. Scope. Building size, foundation types, HVAC configuration, and occupancy determine detector count and placement under the applicable standard. That scope goes in writing before anything is deployed.
2. Measure. Detectors placed to standard, under the building conditions the standard requires. In occupied buildings the work is planned around your operating hours.
3. Report. Documented results you can hand to a board, a lender, a licensing agency, an insurer, or a buyer.
4. Design and mitigate, if the numbers call for it. Suction field layout designed around the actual building rather than a template, with fans sized to measured demand.
5. Verify. Post-mitigation testing, in writing. The job is finished when the numbers say it is.
Since January 1, 2013, Kentucky law has required certification to perform radon measurement or mitigation for compensation. It is administered by the Kentucky Board of Radon Safety. Homeowners testing their own home are exempt. Anyone you pay is not.
Before hiring anyone for a commercial building, ask for the certification and verify it. We would rather you check than take our word for it. Our Warren County radon resource page lists where to look it up.
Commercial radon work is quoted per building, because detector count, foundation complexity, and HVAC configuration drive the number, and no two buildings share all three.
What we will say up front: an RRNC rough-in at construction is the least expensive radon protection available by a wide margin, and expect it quoted alongside the retrofit cost so you can see the difference before you decide.
Every quote is itemized, in writing, before any work starts.
Do Kentucky schools and daycares have to test for radon?
Testing is not universally mandated in Kentucky, but it is recommended by the EPA and is increasingly expected by licensing bodies, insurers, and parents. Districts and centers that test tend to do it before somebody asks rather than after.
Can you test an occupied building?
Yes. Most commercial testing happens in occupied buildings. The standard specifies the building conditions required during the test, and placement is planned around your operations.
How long does commercial testing take?
Short-term measurement is typically 48 hours of deployment, but scoping and placement scale with building size. Larger buildings mean more detectors, not a longer wait.
We’re breaking ground soon. When should we call?
Before the sub-slab material goes down. Once the slab is poured, the rough-in option is gone and you are looking at retrofit pricing.
Does a passive system count as mitigation?
Only if the post-occupancy test says so. Passive systems sometimes reach the target on their own and sometimes do not. The test is what settles it.
Radon in a commercial building is a measurable problem with a documented fix. The first step is a number.
