What the Radon Hazards Disclosure Form Is and When it Matters

The Radon Hazards Disclosure Form documents whether a property has been tested for radon, the results of any tests, and any known mitigation measures or ongoing issues. It is typically completed by the seller during a residential real estate transaction to inform buyers about potential radon exposure in the dwelling, and to meet state or local disclosure rules where they apply.

Why a Clear Radon Disclosure Protects All Parties

A complete Radon Hazards Disclosure reduces legal risk, supports informed buyer decisions, and clarifies responsibility for testing or mitigation. Accurate disclosures improve transaction transparency and can limit post-closing disputes related to latent environmental hazards.

Why a Clear Radon Disclosure Protects All Parties

Who Typically Prepares and Reviews This Disclosure

The Radon Hazards Disclosure is most often prepared by the seller and reviewed by the buyer, listing agent, and closing attorney or title company.

  • Buyers — review test results and mitigation history before closing.
  • Sellers — complete and sign the disclosure to describe known conditions.
  • Real estate agents — collect, verify, and attach the disclosure to transaction files.

Keep copies of the completed disclosure with other closing documents and share electronic copies with all parties involved in the transaction.

Core Elements a Professional Disclosure Should Include

A professional Radon Hazards Disclosure should present clear test results, dates, testing methods, any mitigation performed, and the identities of testers. Include concise explanatory language and space for signatures, dates, and attachments of lab reports or mitigation invoices.

Property ID

Street address, unit number, and legal description to uniquely identify the property for the record.

Test Result

Numeric radon reading in picoCuries per liter (pCi/L), the testing date, and whether short-term or long-term test methods were used.

Testing Provider

Name and contact of the testing company, license or certification details if applicable, and chain-of-custody notes.

Mitigation Details

Description of any radon mitigation system, installation date, installer name, and any maintenance records.

Seller Statement

Seller’s attestation about known radon conditions and whether additional tests were performed after mitigation.

Signature Block

Signature fields for seller(s), date, and space for buyer acknowledgement or initial receipt.

Property Address: Street, city, state, ZIP code.

How to Configure an Online Disclosure Workflow

When delivering the disclosure electronically, set up fields and routing to match the transaction order and authentication needs.

Field Configuration
Signature Fields Place seller signature, date, and buyer acknowledgment fields in order.
Attachments Require upload for test reports and mitigation receipts.
Routing Order Send to seller first, then buyer, then closing/title agent.
Authentication Require email verification or SMS code for signer identity.

Digital Signing: Technical and Compliance Considerations

Electronic delivery is common, but configure the platform for auditability and legal compliance.

  • File Formats: Use PDF or DOCX to preserve layout and attachments.
  • Authentication Options: Email link, SMS code, or stronger multi-factor methods as required.
  • Audit Trail: Capture timestamps, IP addresses, and signer actions.

Ensure the e-signature provider supports ESIGN/UETA compliance, secure storage, and exportable audit records to reproduce the signed disclosure if needed.

Key Timing Considerations During a Real Estate Transaction

Timing for disclosure actions depends on the contract, local law, and inspection contingencies. Note the following common touchpoints.

When to Provide:

Usually delivered during offer/due diligence or when requested by buyer.

Testing Window:

Conduct radon testing during the inspection period before acceptance.

Mitigation Scheduling:

Allow time for mitigation and follow-up tests before closing if required.

Record Retention:

Keep disclosure copies with closing documents per retention rules.

Late Disclosure:

Late or inaccurate disclosures can delay closing or trigger renegotiation.

Transaction Milestones for Radon Disclosure and Testing

A typical sequence aligns inspection, testing, disclosure, and closing; monitor each milestone to avoid delays.

01

Listing Published

Seller prepares disclosure and gathers existing test records.

02

Inspection Period

Buyer orders radon test and reviews seller disclosures.

03

Test Results

Result submitted to buyer and attached to disclosure.

04

Closing

Final disclosure provided to closing agent and included in file.

Common Mistakes to Avoid When Preparing the Form

  • Failing to attach or reference the official lab report when listing test results, which prevents independent verification and may cause disputes.
  • Using nonstandard date formats or omitting the test method (short-term vs long-term), reducing the usefulness of the result to buyers.
  • Leaving the mitigation section vague or unsigned, which can create uncertainty about responsibility for future repairs.
  • Assuming e-signatures are acceptable everywhere without confirming state rules or consumer-disclosure requirements under federal law.

Consequences of Incomplete or Incorrect Radon Disclosures

Civil Liability: Buyer claims or rescission risk.
Contract Delay: Closing postponed for corrections.
Title Issues: Missing documents complicate title insurance.
Regulatory Risk: State penalties if statute requires disclosure.
Insurance Impact: Underwriting questions or exclusions.
Reputational Harm: Broker or seller credibility damaged.

Who Usually Signs the Disclosure and Why Their Role Matters

Seller / Property Owner

The seller signs to attest to known radon conditions, testing performed, and mitigation status. Accurate seller signatures allocate disclosure responsibility and support clear title transfer.

Listing Agent / Broker

The listing agent collects and stores the disclosure in the brokerage file, confirms attachments, and ensures the document is delivered to buyers per contract and state law.

Practical Examples of Radon Disclosure Use in Transactions

Two concise scenarios show how the disclosure functions in common sale contexts.

Seller Discloses Prior Test

A seller provides a short-term test showing 6.2 pCi/L

  • Buyer orders a confirmatory long-term test during inspection
  • The parties agree on mitigation credit and document the system installation and warranty before closing.

Mitigation Installed Before Sale

Homeowner installs an EPA-recommended mitigation system and obtains post-mitigation readings under 2.0 pCi/L

  • Installer supplies a certificate and invoice
  • Seller attaches both to the disclosure and notes ongoing maintenance instructions for the buyer.
