Do tenants legally have to sign?

Signing practices vary by state and lease terms. Having a tenant sign documents acknowledges receipt and helps prevent later disputes; unsigned receipts are weaker evidence in disagreements.

Can the disclosure be e-signed?

Electronic signatures are generally acceptable under ESIGN and UETA where applicable. Confirm any state-specific exceptions and ensure the eSignature platform provides an audit trail and record retention.

What if testing shows high radon levels?

Notify tenants, schedule mitigation, and update the disclosure after remediation. High results typically trigger recommended mitigation actions and may affect leasing decisions.

Who pays for radon testing or remediation?

Payment responsibility depends on lease terms or local law. Landlords commonly pay for initial testing and mitigation, but contracts can allocate costs differently subject to disclosure.

How should disclosures be stored?

Retain signed disclosures in the lease file and backup electronically. Use secure storage with timestamps and access controls to preserve integrity and evidentiary value.

Is notarization required?

Notarization is rarely required for a radon disclosure itself, but some jurisdictions may impose notary or witness requirements; check state rules before assuming none are needed.

What the Tenant Radon Disclosure Is and Why It Matters

A Tenant Radon Disclosure is a written notice provided by a landlord or property manager to prospective or current tenants that informs them of known radon levels in a rental unit or building, any prior radon testing, and remediation history. It documents whether radon testing has been conducted, the test dates and results when available, and any steps taken to reduce radon. The disclosure helps occupants understand potential indoor air quality risk and creates a record that the property owner communicated environmental information before lease acceptance.

Why Including a Clear Radon Disclosure Protects All Parties

A clear Tenant Radon Disclosure reduces legal uncertainty, supports informed tenant decisions, and documents landlord compliance with disclosure duties under state and local rules. It also helps manage liability by creating a dated record of what tenants were told prior to occupancy.

Who Typically Prepares and Receives This Disclosure

The Tenant Radon Disclosure is used by anyone involved in residential leasing where radon is a concern or where local law requires disclosure.

Landlords and property managers who list or lease residential units and must communicate environmental conditions before lease execution.
Tenants and prospective renters who need information to assess health and safety risks associated with indoor radon exposure.
Real estate brokers and leasing agents who handle documentation and deliver disclosures as part of the rental process.

Use the disclosure early in the leasing workflow—ideally at listing or prior to lease signing—to ensure consent and avoid disputes.

Core Elements to Include in a Professional Tenant Radon Disclosure

A compliant disclosure is concise but comprehensive: it identifies testing history, results, remediation, signatories, and how tenants can obtain more information or request further testing.

Property ID

Street address, unit or apartment number, city, state, and ZIP to uniquely identify the rental unit covered by the disclosure.

Testing History

Dates and types of radon tests performed (short-term 48–72 hour or long-term), including who conducted the test and whether testing met EPA or state protocols.

Test Results

Numeric radon levels reported (in pCi/L) and whether results exceeded the action level used by the state or EPA guidelines.

Remediation Status

Description of any mitigation systems installed, the date of remediation, and whether follow-up testing confirmed reduced radon levels.

Tenant Acknowledgment

Signature and date lines for tenant and landlord demonstrating receipt, even when testing is not required or available.

Additional Info

Contact details for the party responsible for testing or remediation and guidance on where tenants can get independent testing.

Step-by-Step: Completing and Delivering the Radon Disclosure

Follow this sequence to prepare, document, and share a Tenant Radon Disclosure consistently during the leasing process.

01

Gather Records: Collect any existing radon tests, mitigation invoices, and contractor reports.
02

Complete Form: Fill address, test dates, results, and mitigation details in the disclosure fields.
03

Have Parties Sign: Obtain signatures from landlord and tenant and date the document.
04

Distribute Copies: Provide signed copies to tenant and retain originals in landlord records.

Where the Completed Disclosure Goes and Who Receives It

A clear routing plan reduces disputes: the tenant receives a copy, the landlord retains originals, and property management records are updated.

Tenant Copy: Deliver signed disclosure to tenant before or at lease signing.
Landlord Records: File the original in the property compliance folder or lease file.
Agent Files: Retain a copy with the leasing agent or broker records when applicable.
Regulatory Submission: Submit to local authority only when required by ordinance or state rule.

Digital Signing and File Formats for Radon Disclosures

Electronic completion and e-signatures are commonly used to streamline disclosures where permitted by state law and landlord policy.

File Types: PDF and DOCX are acceptable for signed records.
Authentication: Use email link or SMS code; stronger ID methods for higher assurance.
Integrations: Platforms commonly integrate with Salesforce, Microsoft 365, NetSuite, Google Workspace.

When using an eSignature platform, ensure it supports audit trails, secure storage, and the document formats your recordkeeping system requires.

Timing: When to Provide the Radon Disclosure and Next Steps

Provide disclosures at specific points to conform with best practice and likely legal expectations; adjust timing to match local rules.

Before Lease Execution:

Deliver disclosure prior to tenant signing the lease.

After Testing:

Provide results within a reasonable period after test completion, typically within 7 days.

Prior to Occupancy:

Ensure tenants receive disclosure before taking possession of the unit.

When Remediation Occurs:

Update and redistribute disclosure after mitigation or follow-up testing.

Record Updates:

Retain updated disclosures in landlord records for the lease term and beyond.

Common Preparation and Delivery Errors to Avoid

Using vague language or omitting numeric test results, which reduces the disclosure's usefulness and can create disputes.
Failing to update the disclosure after mitigation, leaving tenants without current information about radon levels.
Providing the disclosure only after move-in, which can be inconsistent with tenant rights and local ordinances.
Using inconsistent address or unit identifiers, which can cause record mismatches during audits or tenant inquiries.

Consequences of Incomplete or Incorrect Disclosures

Civil Liability: Tenant damages and breach claims possible.

Administrative Fines: Local code violations may incur fines.

Lease Challenges: Tenant may seek lease termination.

Insurance Issues: Claims could be disputed by insurers.

Reputational Risk: Negative listings or complaints may follow.

Remediation Costs: Court orders may require landlord-funded mitigation.

Real-World Examples of Using a Tenant Radon Disclosure

Two concise scenarios illustrate how disclosures function in everyday leasing contexts and the practical outcomes they support.

Property Manager Example

A manager finds an older test showing elevated radon levels and records the result in the disclosure to notify tenants.

The manager schedules mitigation within 30 days.
Documenting the test, mitigation vendor, and follow-up lowers the risk of tenant complaints and demonstrates due diligence for future inspections or liability claims.

Tenant Inquiry Example

A prospective tenant requests radon history before signing a lease and receives a completed disclosure with numeric results.

The tenant reviews remediation notes.
Having the disclosure enabled the tenant to decide to lease with awareness, and the signed acknowledgment protected both parties by establishing that the tenant received material environmental information.
