Colorado Required Lease Disclosures

Colorado mandates that residential landlords provide specific pieces of information to tenants either explicitly within the lease agreement or as formalized addendums prior to move-in.

[!CAUTION] Adverting Transparency Rule (2026): Under HB 1090 (effective January 2026), landlords must disclose all mandatory, unavoidable fees directly in their initial rental advertisements. Furthermore, "junk" payment processing fees are prohibited.

Federal Mandatory Disclosures

1. Lead-Based Paint

Under federal law, if your rental property was built before 1978, you must explicitly provide:

• An EPA-approved information pamphlet on identifying and controlling lead-based paint hazards.
• Any known information or specific reports regarding lead-based paint existing in the specific rental unit.
• A Lead Warning Statement integrated directly into the lease agreement, signed by both the landlord and tenant.

State Mandatory Disclosures

While Colorado is relatively lenient compared to coastal states regarding specific state-level disclosures (like mold or localized flood plains, though local municipalities may differ), landlords should strictly adhere to the following implied and indirect disclosures to avoid liability:

1. Habitability Disclosures

Under the "Warranty of Habitability" statute (further amended in 2024 via SB 24-094), landlords implicitly disclose that the property meets rigorous safety standards at move-in. If pre-existing issues exist (such as a broken window or failing roof) they must be explicitly noted, though landlords cannot waive their fundamental duty to repair critical life-safety issues simply by disclosing them.

2. Bed Bugs

Colorado law requires tenants to promptly inform landlords if they suspect a bed bug presence. Conversely, landlords have strict response protocols. Most importantly: If a prospective tenant asks about recent bed bug infestations, the landlord is legally required to disclose whether the unit has been recently infested and remediated.

3. Identity of Property Manager/Owner

Tenants have a legal right to know the identity of the person authorized to manage the premises, and the identity and address of the property owner (or their authorized agent) for the purpose of serving legal notices and receiving demands (such as demands for security deposit returns or maintenance requests).

Local Ordinances

Cities like Denver and Boulder have their own specific residential rental licensing programs. Denver landlords must often provide a copy of their active Residential Rental Property License alongside the lease, accompanied by a localized "Tenant Rights and Resources" disclosure document mandated by the city government.
