Colorado Notice to Terminate Rental Agreement

[Emilio Ramirez]

Hello Colorado Landlords,

My friend is on a verbal month to month rental agreement. What does the law require from the landlord regarding notice to terminate rental agreement. I found the information below, but it is unclear if only 10 days are required or 10 days plus 30?

Thanks.

Termination of a Month-to-Month Lease

A month-to-month lease is a rental agreement for a one-month period which is renewed automatically each month for another month until properly terminated by either party. A month-to-month tenancy is usually created when a tenant moves into the unit and begins to pay rent on a specified date without signing a lease. A month-to-month tenancy can also be created using a written lease.

To terminate a month-to-month lease, State law requires that written notice of intent to terminate must be given at least ten days before the last day of the rental month which has already been paid, that is, eleven days prior to the next rental payment due date. In a written lease, for example, start from the day when the rent is due then count back ten days. To terminate a month-to-month tenancy the tenant or the landlord (whoever is initiating the termination) needs to provide written notice of intent to terminate by mailing or hand-delivering a copy of the notice to the other party.
