Buyer Acknowledgment and Advisories

Buyer acknowledges receipt of the radon information provided above and understands that radon is a naturally occurring, colorless, odorless radioactive gas that may pose a health risk where present at elevated concentrations.

Recommended action level for radon concentrations is generally recognized at 4.0 picocuries per liter (pCi/L); concentrations at or above that level warrant consideration of mitigation measures. Neither Seller nor any agent guarantees that radon is absent or below any particular level at any future date.

Buyer is advised to obtain, at Buyer's expense, any independent radon testing or inspection Buyer deems appropriate prior to closing. Buyer further acknowledges that any mitigation system described herein is not guaranteed and independent evaluation is recommended.

Seller Certification

Seller certifies, under penalty of law to the best of Seller's actual knowledge, that the information contained in this Radon Disclosure Form is true and accurate as of the Date of Disclosure. Seller further affirms that any documents or test reports in Seller's possession have been provided to Buyer or identified in this form.

Remedies, Indemnity, and Governing Law

If Seller knowingly fails to disclose material information regarding radon or a mitigation system as required by applicable law, Seller shall be liable for actual damages and any reasonable remedies available to Buyer under the purchase agreement or law. Seller agrees to indemnify and hold Buyer harmless for claims resulting from Seller's intentional or reckless nondisclosure.

This Radon Disclosure Form shall be governed by the laws of the state in which the property is located. This form, together with any attached radon reports expressly referenced, constitutes the entire radon disclosure agreement between the parties regarding the matters disclosed herein.

What the Radon Disclosure Form Is and when it matters

The Radon Disclosure Form is a written statement provided by a property seller, landlord, or agent that notifies buyers or tenants about known radon testing results, mitigation systems, or the absence of testing. It documents material information related to radon gas in the property, including measured levels, dates of testing, and any remediation performed. In many real‑estate transactions the disclosure is part of the seller’s property condition disclosures or a lease addendum and helps manage risk by placing radon-related facts on the record prior to transfer or occupancy.

Why completing a clear Radon Disclosure Form benefits the transaction

A complete disclosure reduces post‑closing disputes, supports informed consent by the buyer or tenant, and creates a documented record of known radon conditions for liability management.

Why completing a clear Radon Disclosure Form benefits the transaction

Who typically completes and reviews this disclosure

The Radon Disclosure Form is most often prepared by sellers, leasing owners, real estate agents, property managers, or attorneys involved in a sale or lease.

  • Sellers and landlords providing factual property condition information before closing or occupancy.
  • Buyers and tenants reviewing radon test results and mitigation disclosures prior to acceptance.
  • Real estate agents, brokers, and closing attorneys coordinating disclosure delivery during contract contingencies.

Keep a signed copy with the transaction file and provide an executed copy to all parties to document that radon-related facts were disclosed.

Core sections to include in a professional Radon Disclosure Form

A well-structured form groups facts, test data, mitigation status, seller statements, and signature blocks so each item is clear and verifiable during closing and post‑closing review.

Property Details

Full street address, unit or condo identifier, and parcel or tax ID where available to unmistakably identify the property.

Testing Data

Provide test date(s), testing method (short‑term, long‑term), measured radon concentration in picoCuries per liter (pCi/L), and lab or tester identification if applicable.

Mitigation Status

Indicate whether a mitigation system is installed, the installation date, the installer’s name, proof of functionality testing, and maintenance instructions.

Seller Statements

State whether the seller knows of other radon hazards, whether any tests were refused or unavailable, and any promises previously made about remediation.

Buyer/Tenant Acknowledgment

Acknowledgment language confirming the buyer/tenant received, reviewed, and understands the disclosed radon information prior to contract acceptance.

Signature Block

Signature lines for seller(s), buyer(s), agent(s), with printed names, dates, and space for notarization where required by law or contract.

Timing: when to deliver the Radon Disclosure in a sale or lease

Deliver the completed disclosure at contract offer, during inspection contingency, or at lease signing according to the agreement timeline.

Before Offer Acceptance:

Provide known test results when listing or during negotiations.

Inspection Contingency:

Supply test documentation during buyer inspections.

Prior to Closing:

Ensure executed disclosure is included in closing documents.

Lease Signing:

Deliver to tenant with lease and obtain acknowledgment.

Post-Repair Verification:

Provide post-mitigation test within contract timeframe.

Common mistakes to avoid when preparing the disclosure

  • Missing or incomplete test dates that make results unreliable for current transactions and may trigger re-testing.
  • Failing to include installer or lab identification, which makes verification of mitigation or test validity difficult.
  • Using vague language such as 'low levels' instead of numeric pCi/L measures and the testing method used.
  • Not retaining a signed copy in the transaction file, which increases risk in post‑closing disputes or title issues.

Legal and financial risks from incorrect or omitted disclosures

Contract Rescission: Buyer may seek to rescind sale
Damage Claims: Liability for remediation costs
Settlement Costs: Attorney fees and settlements
Title Delays: Escrow or insurance complications
Regulatory Fines: State enforcement actions possible
Reputation Harm: Broker or seller credibility loss
