Colorado Late Rent Laws for Landlords

Colorado overhauled its late fee rules in 2021: a 7-day wait, a statutory cap, and a ban on evicting over late fees alone. It also requires a 10-day notice for unpaid rent and limits how often you can raise rent.

Late fees in Colorado

The greater of $50 or 5% of the past-due rent (C.R.S. §38-12-105). The fee must be disclosed in the lease, and you can't evict a tenant solely for unpaid late fees.

Whatever the state allows, a late fee is only enforceable if it's written into your lease: the amount, when it applies, and whether it's a one-time or daily fee. If the lease is silent, you generally can't charge one. Use our late fee calculator to check a fee against Colorado's rules before you put it in a lease.

Grace period

7 calendar days. No late fee until rent is at least 7 days late.

Even when the law doesn't require one, a short grace period of 3–5 days is common. It gives tenants room for weekends and bank delays and makes your late fee easier to defend. Learn more in our rent grace period guide.

Notice for unpaid rent

10-day written demand for rent or possession for most residential tenancies (C.R.S. §13-40-104).

Serve notices exactly the way the statute describes: the right number of days, the right delivery method, and only the amounts the notice is allowed to demand. A defective notice usually means starting the clock over. Our pay or quit notice template shows what a notice typically includes.

Security deposits

Return within one month of move-out, or up to 60 days if the lease says so, with an itemized statement (C.R.S. §38-12-103).

Rent increases

Landlords can't raise rent more than once in any 12-month period, and month-to-month tenants or tenants without a written lease need at least 60 days' written notice of an increase (HB21-1121).

Use the rent increase calculator to work out the new amount and the earliest date it can take effect.

Local rules

Denver and some other cities have additional rental licensing and tenant protection rules.

A typical late rent timeline in Colorado

StageWhat happens
Due dateRent due (e.g. the 1st). A reminder 3–7 days before is the best way to avoid the rest of this table.
Earliest late feeAround the 8th (rent due on the 1st must be at least 7 days late).
Formal notice10-day written demand for rent or possession for most residential tenancies.

Most late rent never needs to reach the formal notice stage. Tenants who get a clear reminder a few days before rent is due, and another on the due date, pay on time far more often. That's exactly what automated reminders are for.
