⚡ Colorado Quick Facts
Your Rights as a Colorado Tenant with a Pet
Colorado has some of the most comprehensive tenant protections in the Rocky Mountain region, and recent legislative activity has made it even stronger. Colorado Revised Statutes (CRS) § 38-12 provides the baseline framework, and cities like Denver and Boulder have layered on additional protections that go beyond state law. If you're a Denver renter, you may have more rights than you realize.
Colorado's Deposit Cap: Critical Math for Pet Owners
Under CRS § 38-12-102.5, a Colorado landlord cannot collect a total security deposit exceeding two times the monthly rent. This cap applies to the combined total of all deposits — security deposit, pet deposit, key deposit, and any other refundable deposit collected at or before move-in.
This is one of the strongest deposit cap protections in any major Sun Belt/Mountain West state. If your monthly rent is $2,000, your total deposits (all combined) cannot legally exceed $4,000. Many landlords try to separate a "pet deposit" from a "security deposit" to circumvent this cap — but Colorado courts have generally treated all refundable deposits as subject to the combined cap.
Colorado also requires that security deposits be returned within 30 days of lease termination (or 60 days if the lease explicitly provides for it), along with an itemized written statement of any deductions.
Denver's 2024 Renter Protections: What Changed
Denver passed significant renter protection ordinances in 2024 that created additional layers of tenant rights beyond state law. Key developments include:
- Source of income protections — expanded to cover more categories of renters
- Notice requirements — landlords must provide longer advance notice for rent increases above a certain threshold
- Relocation assistance provisions for no-fault evictions
While these ordinances don't specifically address pet fees, they reflect Denver's increasingly tenant-friendly regulatory environment. Denver has a dedicated Denver Office of Housing Stability (HOST) that handles renter complaints and may assist with Fair Housing issues.
Boulder: Extra Protections
Boulder has long maintained stronger tenant protections than the state minimum. Boulder's Tenant Protections Program includes mediation services, and the city's Fair Housing enforcement has historically been active. Boulder renters dealing with ESA discrimination have multiple complaint pathways available — HUD, state, and the city's own programs.
ESA Protections in Colorado
As everywhere in the US, the federal Fair Housing Act fully protects ESA owners in Colorado. Colorado's own Anti-Discrimination Act (CADA), enforced by the Colorado Civil Rights Division (CCRD), also prohibits housing discrimination based on disability — providing a parallel state-level enforcement mechanism.
- Colorado landlords cannot charge any fees for documented ESAs, including through PetScreening or similar platforms
- The Colorado deposit cap does not apply to ESA-related charges — because those charges should be zero
- Colorado landlords can request written documentation from a licensed Colorado-registered healthcare provider for ESA accommodation — but cannot demand diagnoses or medical records
- Retaliating against a tenant who requests an ESA accommodation violates both the FHA and CADA
What Landlords CAN Legally Do in Colorado
- Charge pet deposits within the 2x monthly rent combined deposit cap
- Charge non-refundable pet fees if clearly disclosed in the lease
- Charge monthly pet rent for conventional pets (Denver ordinances may apply)
- Restrict pet types or sizes in lease terms for conventional pets
What Landlords CANNOT Do in Colorado
- Collect total deposits exceeding 2x monthly rent
- Charge any fees whatsoever for documented ESAs or service animals
- Require ESA owners to use paid third-party pet screening services
- Withhold deposits beyond the 30/60-day return window without itemized statement
- Retaliate against tenants asserting Fair Housing or CADA rights
