Colorado Required Lease Disclosures
The Colorado Revised Statutes, which have governed the state's legal framework since their effective adoption in 1885, mandate 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] Advertising Transparency Rule: Under the Protections Against Deceptive Pricing Practices Act (HB 25-1090 / C.R.S. § 6-1-737), effective January 1, 2026, landlords must disclose the "total price" (including all mandatory, unavoidable fees) directly in their initial rental advertisements and lease agreements. Under C.R.S. § 6-1-737(2)(b), a landlord may only charge a payment processing fee if they also provide the tenant with at least one alternative payment method that does not require a fee.

Federal Mandatory Disclosures
1. Lead-Based Paint
Under the federal Residential Lead-Based Paint Hazard Reduction Act of 1992 (42 U.S.C. § 4852d), 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
Colorado has recently expanded its disclosure requirements to include environmental hazards and fee transparency. Landlords must strictly adhere to the following statutory mandates:
1. Radon Gas Disclosure
Under SB 23-206 (codified at C.R.S. § 38-12-803), landlords must provide tenants with a specific bold-faced radon warning statement and the most recent radon educational brochure from the Colorado Department of Public Health and Environment (CDPHE) before signing a lease. Landlords must also disclose any known records of radon testing or mitigation systems at the property, and the tenant must sign an acknowledgment of this disclosure.
2. Bed Bug History (C.R.S. § 38-12-1005)
Upon request from a prospective tenant, a landlord must disclose in writing whether the dwelling unit contained bed bugs within the previous eight months. The landlord must also disclose the last date the unit was inspected and found to be free of bed bugs. Pursuant to C.R.S. § 38-12-1002, landlords are also prohibited from renting a unit they know contains an active bed bug infestation.
3. Methamphetamine Laboratory Disclosure
Under C.R.S. § 38-35.7-103, a landlord must disclose in writing if they have actual knowledge that the property was used as a methamphetamine laboratory. This applies to all "residential real property," which the statute explicitly defines to include rental properties and apartments. This disclosure is waived if the property has been state-certified as remediated to the standards set forth in C.R.S. § 25-18.5-102.
4. Identity and Address for Service
Per C.R.S. § 38-12-801(2), every written rental agreement must include the name and address of the landlord or the landlord’s authorized agent for the purpose of receiving notices and service of process. If the identity of the landlord or agent changes, the new party must provide written notice or post the new identity in a conspicuous location within one business day.
5. Warranty of Habitability
Under C.R.S. § 38-12-503, landlords implicitly disclose that the property is fit for human habitation. Pursuant to SB 24-094, all residential leases entered into or renewed on or after January 1, 2025, must include a statement in at least 12-point bold-faced type, in both English and Spanish, stating that the tenant is entitled to safe and healthy housing and that retaliation for reporting unsafe conditions is prohibited.
Local Ordinances
Cities like Denver and Boulder have additional requirements. For example, Denver landlords must provide a copy of their Residential Rental Property License and the city-mandated Tenant Rights and Resources document. Failure to comply with local licensing can result in fines and the inability to legally collect rent.
Centralize Your Disclosures
Failing to provide a lead-paint addendum or a radon disclosure can invalidate eviction attempts and lead to severe civil penalties. Landager allows you to attach required disclosures as mandatory, digitally signable addendums during your automated onboarding flow.

Frequently Asked Questions
▶What disclosures must Colorado landlords provide to tenants?
Colorado landlords must provide certain disclosures to tenants before or at the time of lease signing. Common required disclosures include lead-based paint hazards (for pre-1978 buildings, a federal requirement), the identity of the landlord or property manager, and any known material defects in the property. Additional state-specific disclosures may include flood risk, mold hazards, and environmental conditions.
▶What are the Colorado landlord-tenant laws every property owner should know?
Colorado's residential rental market has undergone a dramatic legislative transformation in recent years. Sweeping updates in 2024 and 2025 significantly increased tenant protections, most notably enacting "For-Cause" eviction policies, strict caps on late fees, and brand new limits on security deposits effective in 2026. This guide covers the essential compliance requirements for property owners and landlords.
Read the complete guide▶What is the Colorado eviction process and how long does it take?
The Colorado eviction process requires landlords to provide written notice to tenants before filing a court action. The type and length of notice depends on the reason for eviction — typically shorter for non-payment of rent and longer for lease violations or no-fault terminations. Self-help evictions (changing locks, removing belongings, shutting off utilities) are illegal in Colorado. The full court process varies but typically takes several weeks.
Read the complete guide▶What are the Colorado security deposit rules and return deadlines?
Colorado has specific rules governing how much landlords can charge for security deposits, how deposits must be held, and the deadline for returning deposits after a tenant moves out. Landlords must provide an itemized statement of any deductions made from the deposit. Failure to comply with deposit return deadlines can result in penalties and the forfeiture of the landlord's right to claim deductions.
Read the complete guide▶What are the Colorado rent increase laws and caps for landlords?
Colorado has specific rules governing when and how landlords can increase rent. During a fixed-term lease, rent generally cannot be increased unless the lease explicitly allows it. For month-to-month tenancies, landlords must provide proper written notice before an increase takes effect. Check whether Colorado has any local rent control ordinances that may impose additional caps or requirements.
Read the complete guide▶What is the grace period for late rent in Colorado?
Colorado has specific rules regarding grace periods for late rent and the amount that can be charged as a late fee. Late fee provisions must be stated in the lease agreement, and fees must be reasonable. Check Colorado state law and any applicable local ordinances for the exact grace period and late fee limits that apply to your rental property.
Read the complete guide▶What are the Colorado lease requirements for rental properties?
Colorado recognizes both written and oral leases, though written leases are strongly recommended for terms longer than one year. Lease agreements should include the rent amount, payment due date, security deposit terms, maintenance responsibilities, and rules regarding entry, pets, and subletting.

Read the complete guide▶What are Colorado landlord maintenance obligations and habitability standards?
Colorado landlords must maintain rental properties in a condition that is fit for habitation and complies with applicable building, housing, and health codes. This includes maintaining structural integrity, plumbing, heating and cooling systems, electrical systems, and pest control.
