Colorado Late Fee Laws — Grace Periods, Caps and Illegal Fees (2026)

✓ Law Verified September 2026

Colorado late fee laws decide two things every renter eventually needs to know: how many days you have before a late fee can be charged, and how big that fee is allowed to be. This guide gives the Colorado answer to both in plain English, plus what to do when a fee breaks the rules, verified against official Colorado sources as of September 2026.

Colorado Late Fee Laws at a Glance

How Much A Colorado Landlord Can Charge

The cap: The late fee cannot be more than the greater of 50 or 5 percent of the past-due rent (C.R.S. 38-12-105).

A statute sets the cap, so courts do not need a general reasonableness test. Any fee above the greater of 50 or 5 percent breaks C.R.S. 38-12-105. The statute also says a late fee is not rent, and a lease cannot label it as rent. Separately, HB21-1121 voids unreasonable liquidated-damages clauses and one-way attorney fee clauses in leases.

Under the Colorado late fee laws, the number in the lease is the starting point, not the last word. A fee that is legal in size can still be illegal in timing (charged before the grace period runs), in form (never written into the lease), or in how it is collected.

The Grace Period: When the Clock Actually Starts

Statutory grace period in Colorado: 7 calendar days. Under C.R.S. 38-12-105, a landlord cannot charge a late fee unless rent is at least 7 calendar days late.

A lease can give you more time than the Colorado late fee laws require, but never less. A fee charged inside the grace period is not owed.

Three Rules Landlords Get Wrong

Must the fee be in the lease? YES. The late fee must be disclosed in the rental agreement. The landlord must also give the tenant written notice of the fee within 180 days after the rent was due.

Can it come out of your deposit? UNVERIFIED. The late fee statute doesn’t directly address this. C.R.S. 38-12-103 lists the allowed deposit deductions, and late fees aren’t clearly named there, so check with your court or legal aid.

Can a late fee alone get you evicted? NO. A landlord cannot remove or lock out a tenant, end the tenancy, or start an eviction case only because the tenant hasn’t paid late fees. Only unpaid rent or another lease violation can support an eviction. A landlord also cannot apply your rent payments to late fees first to make the rent look unpaid.

What to Do About an Illegal Late Fee in Colorado

You may be able to refuse an illegal fee and send the landlord written or electronic notice of the violation. The landlord then has 7 days to fix it. If they don’t, you may be able to sue, including in small claims court, for a court order stopping the fee, damages, a penalty of 150 to 1000 per violation, and court costs and reasonable attorney fees. The statute also sets a 50 penalty per violation.

A violation is also treated as an unfair or deceptive trade practice under Colorado consumer protection law.

Whatever the remedy, keep paying the rent itself on time and in full. Dispute the fee separately, in writing, citing the Colorado late fee laws rule it breaks, and keep a copy. Landlords rarely file a case over a disputed fee; they do file over unpaid rent, so never withhold rent to protest a fee.

Do the Math Before You Pay

Take the fee in your lease and compare it to the rent. A fee of a few percent of monthly rent is the range most Colorado courts accept as reasonable; a fee that approaches a week of rent, or one that keeps growing by the day without limit, is the kind that gets thrown out.

Then check the date: count the days from the due date to the day the fee was charged, and set that against the grace period above.

Two numbers decide almost every late-fee dispute, the size of the fee and the day it was charged. Write both down before you call the landlord, because the Colorado late fee laws are easiest to enforce when you can state exactly which rule was broken.

Paper Beats Memory: Protecting Yourself Going Forward

Pay rent in a way that leaves a dated record, a bank transfer, a portal receipt, a check image, so a “late” claim can be answered with a timestamp. If you know rent will be late, tell the landlord in writing before the due date; many will waive the fee once, and the message itself is evidence of good faith.

Keep every fee notice. A pattern of fees charged inside the grace period, or above the cap where Colorado has one, is exactly the evidence a small-claims judge wants to see, and it is the evidence that turns one disputed fee into a refund of every fee you paid.

Recent changes in Colorado: HB21-1121 (2021) created these late fee limits in C.R.S. 38-12-105. Colorado’s junk fees law, HB25-1090, took effect January 1, 2026. It requires landlords to advertise a total price that includes all mandatory fees, and it gives tenants a 14-day written-demand process for getting back prohibited fees.
