Before you start
Information to gather

- Known test history, the most recent records and reports, detected concentrations, and mitigation or remediation details, including system descriptions and documentation.
- The CDPHE brochure linked below. On September 14, 2026, the department’s resource page linked to the February 2024 edition (20 pages), displayed as revision 9 of 9. Obtain the current copy when preparing the lease.
Step-by-step guidance
How to complete this PDF
Choose the knowledge option
In section 1, select the knowledge option that accurately describes what the landlord knows. Use the space below the first option to describe known information and identify attached records.
Do not assume a negative result
Do not treat “no knowledge” as a negative test result or proof that radon is absent.
Provide the separate brochure
Supply the separate brochure before acknowledging section 2. This one-page PDF says the brochure was provided but does not contain it.
Sign and keep the complete packet
Keep section 3’s bold warning legible. Complete the landlord’s signature, printed name and date and the applicable tenant acknowledgment lines before the lease is signed. Two tenant blocks are provided.
Before you use it
Checks and separate documents
Keep the complete packet
Keep the disclosure, brochure and identified records together with the lease, and provide copies to the tenants.
Understand the acknowledgment
A signature records receipt of the disclosure; it does not establish a measured radon level or that a mitigation system works.
