Landlord-Tenant Law Guide
Colorado Landlord-Tenant Laws
Colorado's landlord-tenant landscape shifted significantly in recent years, with the legislature passing stronger tenant protections around eviction, habitability, and security deposit returns. Landlords must be current on these changes — particularly the revised eviction notice periods.
Key Rules at a Glance

No statutory limit
Colorado does not cap security deposits. Market practice is typically 1–2 months' rent.
Deposit Return Deadline
30 days (or 60 if lease specifies)
Itemized written statement required with any deductions. Lease can extend the deadline up to 60 days.
Notice to Enter
24 hours
Colorado requires reasonable notice — 24 hours is the accepted standard. Entry must be at reasonable times.
Rent Increase Notice
21 days (month-to-month)
HB21-1121 (effective 2021) requires at least 21 days notice before a rent increase for month-to-month tenants. For longer terms, lease governs.
Late Fee

No statutory cap. Must be specified in the lease.
Nonpayment Eviction Notice
10-day demand for compliance or right to remedy
HB21-1121 extended the previous 3-day notice to 10 days. Tenant has 10 days to pay rent in full before landlord may file an eviction lawsuit.

21 days
Same 21-day notice requirement applies to terminating month-to-month tenancies.
Disclaimer:Colorado's tenant protections have been expanding — the 2021 eviction notice change from 3 days to 10 days is just one example. Verify current law with a Colorado real estate attorney before taking action.
