Colorado Crime-Free Housing Addendum

This Crime-Free Housing Addendum is built with Colorado as the governing state. These are the Colorado landlord-tenant rules that most often bear on it, with the statute for each.

Colorado rules at a glance

Colorado rules for a Crime-Free Housing Addendum
Nonpayment eviction notice10-day demand (5 days under a qualifying “exempt residential agreement”)C.R.S. §13-40-104(1)(d)
Nonpayment & lease violationsA 10-day written demand to pay or cure is required for residential tenancies (§13-40-104(1)(d), (e)). A landlord who owns five or fewer single-family rental homes may use 5 days only under an “exempt residential agreement” — a lease of a single-family home that itself states the 10-day period doesn’t apply (§13-40-104(5)(b)).
Month-to-month termination21 days under the common reading — 28 or 91 days if the tenancy is read by total length; cause is required for most tenants of 12+ monthsC.R.S. §13-40-107

Ending a Colorado tenancy

Colorado sets the notice to end a tenancy by the length of the tenancy rather than a flat 30 days (§13-40-107(2)). For a month-to-month tenancy, the period usually applied is 21 days, but the 2024 amendments tie the notice to “the length of the applicable tenancy”, and many practitioners read that as total occupancy — 28 days after six months and 91 days after a year — so the longer notice is the safer course. Since 2024, a landlord can rely on these notices alone only where the for-cause rules don’t apply — for example, a tenant who has been in place for less than 12 months (§13-40-107(1)).

  • For-cause eviction — Once a tenant has been in the unit for at least 12 months, a landlord generally can’t end or refuse to renew the tenancy without a statutory cause — such as nonpayment, a lease violation, or one of the no-fault grounds below (§38-12-1303). Owner-occupied single-family homes, duplexes and triplexes, short-term rentals and employer-provided housing are exempt (§38-12-1302).
  • No-fault grounds — Demolition or conversion, substantial repairs, the landlord or a family member moving in, taking the unit off the market to sell, the tenant refusing a new lease on reasonable terms, or rent paid more than 10 days late more than twice during the lease — each generally requiring at least 90 days’ written notice (§38-12-1303(3)). If the landlord can’t show compliance, a court must dismiss the eviction (§38-12-1306).
  • Nonpayment & lease violations — A 10-day written demand to pay or cure is required for residential tenancies (§13-40-104(1)(d), (e)). A landlord who owns five or fewer single-family rental homes may use 5 days only under an “exempt residential agreement” — a lease of a single-family home that itself states the 10-day period doesn’t apply (§13-40-104(5)(b)).
  • Domestic violence — A tenant who is a victim of domestic violence, stalking or unlawful sexual behavior may end the lease early with written notice and qualifying documentation (§38-12-402).
