Should you offer a month-to-month lease?

The intuition is that a month-to-month tenancy gives the landlord flexibility. In Colorado in 2026 that intuition is mostly wrong, and it is worth understanding why before offering one.

What actually changed

Colorado has moved to a framework generally requiring a qualifying just cause to end a residential tenancy or decline to renew it. That framework does not evaporate because the tenancy is periodic.

So the classic reason for preferring month-to-month — "if it does not work out I can just end it" — no longer holds in the way owners expect. Ending a month-to-month tenancy is a legal act requiring a qualifying reason and correct notice, not a matter of preference.

Meanwhile, the tenant can leave on 21 days' notice for any reason at all. That asymmetry is the whole issue. See our Colorado landlord-tenant law guide.

Notice periods

For most residential month-to-month tenancies, 21 days' written notice is the general requirement to terminate — from either side. Shorter tenancy types and specific situations carry different periods, and the just-cause requirements layer on top.

Serve it correctly. A defective notice generally means starting over. See our guide to Colorado notices.

Rent increases

A common misunderstanding: that month-to-month lets you adjust rent freely.

It does not. Colorado generally limits residential rent increases to once in any 12-month period, and that applies to periodic tenancies too. You also cannot use a rent increase as a workaround for a non-renewal you are not otherwise permitted to make. See Colorado rent increase laws.

The turnover problem

Turnover is the largest controllable cost in rental ownership — commonly $2,500 to $6,500 on a typical Front Range property once vacancy is counted. See the arithmetic.

A month-to-month tenant can give notice at any time, including in November, when your property will lease slowly and for less. A fixed term at least lets you choose when the risk arrives.

This matters most in markets with a strong calendar. In Boulder, a tenancy ending outside the spring window costs weeks of vacancy structurally, not occasionally.

When month-to-month genuinely makes sense

• You are selling and need the property available on a timeline you cannot yet fix.
• A renovation is planned but not scheduled.
• You are converting a fixed term and want to keep a good tenant while they decide.
• The tenant is genuinely transitional — between homes, on a short assignment — and the alternative is a vacancy.
• You want to align a lease to the calendar. Running month-to-month for a few months to move a lease end into the strong season is a legitimate and underused tactic.

In several of these a short fixed term — three or six months — serves better, because it gives certainty on both sides.

If you do offer it

• Price it higher. A month-to-month premium is standard and justified by the turnover risk.
• Put everything in writing. A periodic tenancy is still a tenancy and needs a full written agreement — see evicting a tenant with no lease for what happens when it is not documented.
• Review it regularly rather than letting it run for years unexamined.
• Convert good tenants to a fixed term when you can, timed to end in the strong leasing season.
