Colorado Lease Non-Renewal Notice (2026): Requirements + Free Template Preview

End a month-to-month tenancy or decline to renew a lease, with the state-required advance notice.

The Colorado rule

21 days minimum notice

Governing statute: Colo. Rev. Stat. § 13-40-107(1)(c) · Read the statute ↗

Special rule: 21 days for a month-to-month tenancy; longer periods apply to longer tenancies. Under HB24-1098 (2024), after 12 months' occupancy no-fault termination grounds require 90 days' notice — the 21-day figure is safe only for shorter or exempt tenancies.

Data version 2026.07.1, compiled July 2026. Verify with the current statute — laws change, and cities or counties may add stricter requirements.

What a valid Colorado lease non-renewal / termination notice includes

  • • Full names of all tenants and the rental property address
  • • The landlord’s name and mailing address
  • • The exact termination date by which the tenant must vacate
  • • Service at least 21 days before the effective date (Colo. Rev. Stat. § 13-40-107(1)(c))
  • • A certificate of service recording how and when the notice was delivered — courts routinely ask for this

NoticeKit generates all of the above, computes your actual notice period, and warns you — citing Colo. Rev. Stat. § 13-40-107(1)(c) — if your dates fall short of the Colorado minimum.
