Colorado Month-to-Month Rental Agreement

Quick answer: Colorado does not compress the month-to-month termination notice into one fixed number in the sources this page relies on (Since 2024, Colorado landlords need a statutory cause to end most residential tenancies once the tenant has lived in the home for 12 months (Colo. Rev. Stat. 38-12-1303, HB 24-1098), so the landlord side no longer compresses into one fixed number), so verify the current statute and write an explicit notice clause into the agreement. The sections below cover what is verified.

A month-to-month rental agreement in Colorado renews automatically at the end of each rental period until the landlord or the tenant ends it with proper written notice. Colorado does not give landlords a single fixed no-fault notice period, while a tenant generally must give 21 days' written notice under Colo. Rev. Stat. 13-40-107(1)(c).

Since 2024, Colorado landlords need a statutory cause to end most residential tenancies once the tenant has lived in the home for 12 months (Colo. Rev. Stat. 38-12-1303, HB 24-1098), so the landlord side no longer compresses into one fixed number.

Verify before you rely on it

Landlord-tenant statutes change, and cities or counties can add stricter local rules such as just cause ordinances or longer notice for older tenancies. Confirm the current Colorado requirement in the statute cited above (or with your local court's self-help resources) before serving or relying on a termination notice.

Colorado month-to-month rental agreement requirements

Since 2024, Colorado landlords need a statutory cause to end most residential tenancies once the tenant has lived in the home for 12 months (Colo. Rev. Stat. 38-12-1303, HB 24-1098), so the landlord side no longer compresses into one fixed number. Whatever the current rule turns out to be for your situation, write the notice mechanics into the agreement itself, in writing and with a fixed day count, so neither side has to litigate what "reasonable notice" means.

The tenant's side of the same coin: to move out, a Colorado month-to-month tenant must give 21 days' written notice (Colo. Rev. Stat. 13-40-107(1)(c)). Tenants who leave without proper notice typically stay liable for rent through the end of the notice period, so the clause protects the landlord's cash flow as much as the tenant's flexibility.

A month-to-month arrangement changes nothing about deposit law: Colorado sets no statutory deposit cap and requires it back within 30 days (up to 60 if the lease says so) after move-out (Colo. Rev. Stat. 38-12-103). Because month-to-month tenants can leave on short notice, document the move-in condition especially carefully: the deposit accounting deadline arrives fast.

The flexibility cuts both ways on price: a month-to-month landlord can raise the rent going forward with proper advance written notice, subject to any rent regulation that applies in Colorado or your city, and the tenant can respond by giving notice and leaving. Put the change-of-terms mechanics in the agreement so both sides know the rhythm.

Beyond notice and deposit, the agreement should read like any complete rental contract: the parties and every adult occupant, the property address, the rent with its due date, grace period, and late fee, who pays which utilities, maintenance duties, and the rules on pets, smoking, guests, and subletting. A rolling tenancy is not an informal one: every blank you leave becomes an argument later.

Federal law adds one universal requirement worth remembering: for housing built before 1978, the landlord must give the tenant the EPA lead-based paint disclosure and pamphlet before signing. Cities and counties in Colorado can layer on registration, inspection, or rent regulation rules of their own, so a quick check of local ordinances is part of preparing any rental agreement.

How to complete a month-to-month rental agreement in Colorado, step by step

Here is the sequence Colorado landlords typically follow to put a month-to-month rental agreement in place that survives the flexibility it creates.

  1. Screen the tenant first. Run the application, income verification, and references before drafting anything. The short exit makes some landlords casual about screening; resist that, because fair housing law applies from the first contact and a problem tenancy is a problem even at 30 days' notice.
  2. Agree on the business terms. Settle the rent, the deposit, the move-in date, who pays which utilities, and any pet or parking arrangements before filling in the agreement.
  3. Set the notice clause to the statute. Write the termination notice into the agreement: in Colorado, that means the period the current Colorado statute requires. The agreement can give more time than the statute, never less, and both sides should see the same number in the document they sign.
  4. Complete every clause of the agreement. Work through the guided form: parties, property, rent, deposit, utilities, maintenance, and house rules. Where Colorado law sets a boundary, the agreement should match or exceed it, never contradict it.
  5. Attach disclosures and document the condition. Include the federal lead-based paint disclosure for pre-1978 housing and any Colorado or local disclosures, then complete a move-in checklist with dated photos signed by both parties. Month-to-month tenancies can end quickly, and the move-out accounting relies on this record.
  6. Sign and distribute copies. Every adult tenant signs, the landlord signs, and each party keeps a full copy. No notarization is needed; from the first month onward the agreement simply renews until one side serves proper written notice.

Colorado month-to-month rental agreement FAQ

How much notice does a landlord have to give to end a month-to-month tenancy in Colorado?

Colorado does not compress the landlord's notice into one fixed number in the sources this page relies on. Since 2024, Colorado landlords need a statutory cause to end most residential tenancies once the tenant has lived in the home for 12 months (Colo. Rev. Stat. 38-12-1303, HB 24-1098), so the landlord side no longer compresses into one fixed number. Check the current statute before serving notice.

How much notice does a tenant have to give in Colorado?

A Colorado month-to-month tenant must give 21 days under Colo. Rev. Stat. 13-40-107(1)(c) before moving out. Leaving without proper notice generally keeps the tenant liable for rent through the end of the notice period.

Can the landlord raise the rent on a month-to-month tenancy in Colorado?

Yes, prospectively: because the tenancy renews monthly, the landlord can change the rent for future months by giving proper advance written notice, subject to any rent regulation in Colorado or your city. The increase cannot apply retroactively, and the tenant can always respond by giving notice and moving out.

Do security deposit rules apply to a month-to-month rental in Colorado?

Yes, in full. Colorado sets no statutory deposit cap and requires it back within 30 days (up to 60 if the lease says so) after the tenancy ends (Colo. Rev. Stat. 38-12-103), exactly as it would under a fixed-term lease.
