Frequently asked questions

How much notice is required to raise rent in Colorado?

At least 30 days' advance written notice. 60 days' notice required if the increase is 10% or more.

Is there a limit on how much I can raise the rent in Colorado?

Most states have no statewide rent cap, but a few (like California, Oregon, and Washington) do, and some cities have local rent control. Verify before setting the new amount. An increase can never take effect mid-lease unless the lease allows it.

Can a tenant reject a rent increase?

A tenant who doesn't want to pay the new rent can end the tenancy with proper notice. If they stay past the effective date after valid notice, they generally owe the new amount.
