Colorado Month-to-month Rental Agreement Template

A rental agreement with no fixed end date. It renews each month until the landlord or tenant gives proper written notice. This edition fills in the Colorado rules we could confirm and marks the rest as blanks to check.

Colorado rules for this form

Month-to-month notice. A month to month tenancy ends with at least 21 days of written notice, though a landlord also needs a cause allowed by the for cause eviction law. (C.R.S. section 13-40-107 and C.R.S. section 38-12-1303)

Notice before a rent increase. A landlord generally must give at least 60 days of written notice before increasing rent. (Colorado Revised Statutes, title 38, article 12 (rent increase notice))

Notice before a rent increase. Rent may not be increased more than once in any 12 month period. (C.R.S. section 38-12-702)

Deposit limit. A landlord may not require a security deposit larger than two months of rent. (C.R.S. section 38-12-102.5)

Deadline to return the deposit. From January 1, 2026, the landlord must return the deposit within 30 days after the lease ends or the premises are surrendered, whichever is later, unless the lease allows a longer period of up to 60 days. (C.R.S. section 38-12-103 (HB 25-1249))

Notice before entry. No statute sets a notice period for landlord entry, so the lease generally governs access. (Colorado Revised Statutes (no entry notice statute))

Late fees. Late fees are generally capped by statute at the greater of a small flat amount or 5 percent of the past due rent, and the landlord must disclose them in the lease. (Colorado Revised Statutes, title 38, article 12 (late fee rules))

Required disclosures. Homes built before 1978 need the federal lead-based paint disclosure and the EPA pamphlet. (Residential Lead-Based Paint Hazard Reduction Act (42 U.S.C. 4852d))

Required disclosures. Pet deposits are limited and must be refundable. The statute sets a dollar limit on pet deposits. (C.R.S. section 38-12-106)

Cities and counties in Colorado can add their own rules on top of these. Check local ordinances before you sign.

Before you use it

• A month-to-month agreement renews automatically each rental period until someone gives written notice.
• Notice periods to end the tenancy or change the rent are set by state law, and some cities require longer notice or a valid reason.
• The flexibility cuts both ways: the tenant can leave on short notice, so turnover can come sooner.
• Everything else, from deposit limits to entry notice, follows the same rules as a fixed-term lease.
