RADON DISCLOSURE AND NOTICE ═══════════════════════════════════════════════════════════════════════ Transaction: Sale Property: 482 Elm Street, Apt 3B, Portland, OR 97214 Governing state: Oregon EPA radon zone: Zone 2 — moderate potential (2-4 pCi/L predicted average) Seller / Landlord: Riverside Holdings LLC Buyer / Tenant: Jordan Alex Taylor ═══════════════════════════════════════════════════════════════════════ GENERAL NOTICE — RADON Radon is a colourless, odourless, naturally-occurring radioactive gas produced by the breakdown of uranium in soil, rock, and water. It enters buildings through cracks and openings in foundations and accumulates indoors, especially in basements and lower levels. Long-term exposure to elevated radon is the second leading cause of lung cancer in the United States after smoking, and the leading cause among non-smokers (Surgeon General Health Advisory, 2005). The EPA action level is 4 picocuries per litre (pCi/L); the EPA recommends consideration of mitigation between 2 and 4 pCi/L. Indoor radon can be reduced to safe levels by mitigation systems, typically sub-slab depressurisation, often costing $800 to $2,500 for residential installation. ═══════════════════════════════════════════════════════════════════════ PRIOR TESTING ► No prior testing Test date: September 15, 2024 Test result: N/A — no test ═══════════════════════════════════════════════════════════════════════ MITIGATION ► No mitigation system installed Description: Not applicable — no mitigation system installed. (If applicable: type of system (sub-slab depressurisation, etc.), installation date, contractor, post-mitigation test results.) ═══════════════════════════════════════════════════════════════════════ RECOMMENDATION TO BUYER / TENANT The EPA strongly recommends testing every home for radon, regardless of zone or prior testing. Short-term test kits cost $15-30 and are widely available; long-term tests (90+ days) provide more accurate annual averages. State Departments of Health often provide free or reduced-cost test kits. Mitigation is straightforward and effective — homes with elevated radon can almost always be brought below 4 pCi/L with a properly-installed system. ═══════════════════════════════════════════════════════════════════════ CERTIFICATIONS Seller / Landlord certifies the disclosure above is accurate to the best of their knowledge. _______________________________ Date: May 4, 2026 Riverside Holdings LLC Buyer / Tenant acknowledges receipt of this disclosure and the EPA pamphlet "A Citizen's Guide to Radon" (or current equivalent). _______________________________ Date: May 4, 2026 Jordan Alex Taylor
About this template
Radon disclosure varies widely by state. Several states have specific statutory requirements for radon disclosure in real-estate transactions: Illinois (Public Act 094-156), New Jersey, Florida, Maine, Minnesota, and Pennsylvania (for high-radon zones); a few states require radon testing as a condition of sale or lease. Other states leave radon to the general "material defect" disclosure framework. Even where not legally required, disclosure is strongly recommended — radon-related lawsuits are emerging, and EPA position is that radon should be disclosed in all transactions. The EPA action level of 4 pCi/L is roughly equivalent to smoking 8 cigarettes per day in lung-cancer risk for a non-smoker; combined with smoking, the risk is multiplied. Radon levels vary significantly within counties and even within neighbourhoods, depending on soil type, foundation construction, and ventilation — meaning a property in a "low" zone can have elevated levels. The only way to know is to test. Mitigation is highly effective: properly-installed sub-slab depressurisation systems reduce radon by 80-99% and typically cost $800-2,500 residential, with annual operating cost under $100. New construction in many high-zone areas now includes "passive" radon-resistant features that can be activated if testing later shows elevated levels — easier and cheaper than retrofit.

- Property in EPA Zone 1 (high potential) or Zone 2 (moderate).
- Property with finished basement or below-grade living space.
- Property with prior radon testing or mitigation system installed.
What to include
- Property address and EPA zone.
- Prior testing results (with date and pCi/L value).
- Mitigation system status and details.
- Recommendation that buyer/tenant test.
- EPA pamphlet acknowledgement.
- Signatures from all parties.
