Kentucky Radon Disclosure Law for Real Estate Transactions
KRS § 324.360 governs Kentucky residential real estate disclosure. The seller's disclosure form must identify any past radon testing performed at the property, any installed mitigation system, and must include the following written warning: "Radon is a naturally occurring radioactive gas that, when it has accumulated in a building in sufficient quantities, may present health risks, including lung cancer." While Kentucky does not legally mandate pre-sale testing, all major Kentucky realtor associations — Greater Louisville Association of Realtors (GLAR), Lexington-Bluegrass Association of Realtors, and Northern Kentucky Association of Realtors — reference radon testing as standard transaction practice given the state's elevated geological background.
Key disclosure requirements under Kentucky law:
- If radon testing has been performed at the property, the seller must disclose the date and result.
- If a radon mitigation system is installed, the seller must disclose the installation date and the contractor (Kentucky Board of Radon Safety-registered contractors per KRS §§ 309.430-309.454).
- Sellers cannot legally withhold known radon information about the property.
- The penalty for failing to disclose known radon issues includes potential rescission of the sale and damages.
Major Kentucky realtor associations recommend including a radon contingency clause in every Kentucky Real Estate Purchase Agreement, allowing buyers to: (1) conduct radon testing during the inspection period, (2) require seller mitigation if results exceed 4 pCi/L, (3) negotiate cost responsibility, and (4) terminate the agreement if mitigation cannot be completed within the closing timeline.

Realtor FAQ
Kentucky Real Estate Radon Questions Realtors Ask
Frequently Asked Questions
Does Kentucky law require radon testing before a home sale?
Kentucky does not legally require pre-sale radon testing, BUT KRS § 324.360 requires the seller's disclosure form to identify any past radon testing and any installed mitigation system. The form must include a written radon health warning. In practice, most Kentucky real estate transactions now include a radon contingency clause in the purchase agreement, and the Greater Louisville Association of Realtors (GLAR), Lexington-Bluegrass Association of Realtors, and Northern Kentucky Association of Realtors all reference radon testing as standard practice. Many lenders — particularly FHA-backed loans — increasingly request radon testing as a condition of loan approval in Kentucky's extensive Zone 1 areas.
What is the standard radon testing protocol for Kentucky real estate transactions?
For real estate transactions, EPA recommends a short-term test (48-96 hours) using either a charcoal canister or continuous radon monitor (CRM) under closed-house conditions. The CRM method is preferred for transactions because it provides hour-by-hour readings that can detect tampering (windows opened during the test) and supplies a defensible time-stamped result for closing documentation. Kentucky Radon Experts partner contractors use AARST-NRPP-certified Femto-TECH and Sun Nuclear CRMs for all transaction testing.
If a radon test comes back elevated, can mitigation be completed before closing?
Yes. Standard Kentucky real estate transaction radon mitigation timeline: Day 0 — test result received (elevated, >4 pCi/L); Day 1-3 — partner contractor on-site assessment; Day 3-5 — written quote provided; Day 5-7 — buyer/seller agreement on cost responsibility; Day 7-10 — mitigation system installed (typically 4-8 hours of on-site work on a standard Inner Bluegrass slab; Mammoth Cave karst foundations may add a day); Day 11-14 — post-mitigation verification test conducted; Day 14 — final report ready for closing documentation. The full cycle typically takes 7-14 days, fitting within most Kentucky real estate transaction inspection contingency windows. The Kentucky Board of Radon Safety recommends verification testing within 30 days of system activation.
Who typically pays for radon mitigation in a Kentucky real estate transaction?
Across Kentucky transactions, cost responsibility is negotiated between buyer and seller after an elevated test result — the Kentucky Real Estate Purchase Agreement does not mandate which party pays. Roughly half of Kentucky mitigations are seller-paid; the remainder are negotiated cost-shares, closing credits, or buyer-paid. Many Kentucky listing agents now recommend pre-listing radon testing so sellers can mitigate proactively or price-adjust before listing, avoiding mid-transaction disputes.
Are FHA loans different on radon requirements in Kentucky?
HUD Handbook 4000.1 does not require radon testing for FHA-backed loans as of 2026, but HUD strongly encourages radon testing on all FHA-insured properties. Kentucky's 30 EPA Zone 1 counties (including Jefferson/Louisville, Fayette/Lexington, Warren/Bowling Green, Franklin/Frankfort, Scott/Georgetown, Jessamine/Nicholasville) frequently prompt FHA underwriters to request radon test results during underwriting, and many Kentucky FHA lenders include radon testing as part of standard inspection requirements. USDA Rural Development loans similarly encourage testing. VA loans do not require radon testing but VA appraisers may flag elevated radon as a property condition issue.
Can radon testing be done at the same time as a home inspection?
Yes, and this is the standard Kentucky practice. Most Kentucky home inspectors place a continuous radon monitor (CRM) during the inspection and retrieve it 48-96 hours later when they return for the final inspection report walkthrough. Some inspectors are certified to provide radon testing themselves; others coordinate with NRPP-certified, Kentucky Board of Radon Safety-registered partner companies like the Kentucky Radon Experts network. Coordinating testing with inspection compresses the transaction timeline.
Does an existing radon mitigation system need to be tested before transfer of ownership?
Best practice — yes. Post-mitigation verification testing whenever a home with an existing radon system changes ownership confirms the system is functional and currently maintaining indoor radon below the EPA action level of 4 pCi/L. Many Kentucky real estate transactions include verification testing of existing systems as a buyer-protection step. If the seller cannot produce documentation of the original mitigation install plus regular biannual testing, buyers commonly request a current verification test as a condition of closing — especially important for homes on Mammoth Cave karst foundations where soil-gas pathways can shift seasonally.
Kentucky MLS — how should radon mitigation be disclosed in listing notes?
Kentucky MLS listings should disclose: (1) Whether radon testing has been performed and the date + result, (2) Whether a radon mitigation system is installed and the installation date, (3) Date of the most recent post-mitigation verification test and the result, (4) The Kentucky Board of Radon Safety registration of the contractor who installed the system. Sellers who have proactively tested and mitigated typically command faster offers and higher closing prices because radon uncertainty is removed from buyer negotiations. The Greater Louisville Association of Realtors (GLAR), Lexington-Bluegrass Association of Realtors, and Northern Kentucky Association of Realtors all support full radon disclosure on Kentucky MLS listings.
