Security Deposits

In Colorado, the maximum security deposit a landlord can collect is no limit, but must be "reasonable". After a tenant moves out, landlords have 1 month (or up to 60 days if stated in lease) to return the deposit (minus any legitimate deductions for damage beyond normal wear and tear).

Interest on deposits: Not required.

Best practice: Provide an itemized statement of any deductions alongside the returned deposit. Most states require this, and it's your best defense if a tenant disputes charges. Document the unit condition with dated photos at both move-in and move-out.

Notice Periods

Landlord entry24 hours (reasonable)
Rent increase60 days for month-to-month (as of 2023)
Terminating month-to-month21 days
Nonpayment of rent10 days (as of 2021)

These notice periods are statutory minimums. A lease can require more notice than the statute, but it can never require less. If your lease is silent on an issue, the state statute controls.

Late Fees & Grace Period

Late fee limit: Capped at $50 or 5% of rent owed, whichever is greater (as of 2021).
Grace period: 7 days required by statute.

Late fees must be specified in the lease to be enforceable. A late fee that isn't written into the lease generally cannot be collected, even if the state allows it.

Rent Control

No statewide — local rent control was legalized in 2024

Even without statewide rent control, individual Colorado cities and counties may have local ordinances that regulate rent increases. Always check your municipality's rules before raising rent.

Landlord Entry

A Colorado landlord must give 24 hours (reasonable) of notice before entering a rental unit, except in emergencies.

Permitted reasons for entry:

  • Not specified by statute — reasonable notice

Required Lease Disclosures

Colorado landlords must disclose the following in the lease or at lease signing:

  • Lead-based paint
  • Radon (as of 2021)
  • Bed bug history

Missing a required disclosure can give tenants grounds to break the lease or withhold rent — even if the underlying condition is fine. This is low-effort compliance worth getting right.

Eviction Timeline

A typical uncontested eviction in Colorado takes 4-8 weeks typical from filing to lockout, assuming the tenant doesn't answer or fight the case.

Contested evictions take significantly longer, especially if the tenant raises habitability defenses or claims retaliation. Self-help evictions (changing locks, shutting off utilities, removing belongings) are illegal in every state, including Colorado.

Important Notes for Colorado

  • Colorado enacted significant tenant protections 2021-2023.
  • HB 21-1121 limits late fees and rent increases.
  • Warranty of habitability strengthened in 2019 and 2023.
