Security Deposit Rules
in Your Lease
What it actually means, what Colorado law says, what's specific to Denver - and exactly what to do. In plain English.
Quick Summary - What You Need to Know
- There is no legal maximum on a Denver security deposit - Colorado lets the lease set whatever amount the landlord asks for.
- Your deposit is due back within 30 days of the lease ending, or up to 60 days if your lease says so.
- Keeping any part of it requires a written statement listing the exact reasons, not a lump-sum damages line.
- Wrongful retention costs the landlord three times the amount wrongfully withheld plus attorney fees and court costs, after you give at least seven days' notice of your demand and intent to sue.
- Deductions for normal wear and tear were already barred before 2026; the January 1, 2026 change adds damage that preexisted your tenancy.
Understanding the Security Deposit Rules
A security deposit clause sets three things: how much you hand over before you get keys, what your landlord can subtract from it, and how fast you get the rest back. In Colorado, that last part is the piece with teeth - there's no cap on the amount, but there is a hard deadline on the refund.
That matters in Denver, where the size of the deposit is set by the market rather than the legislature. Your leverage isn't the check you wrote - it's the 30-day clock and the itemized statement your property manager owes you after you move out.
What renters assume
Most renters assume Colorado must limit deposits to one or two months' rent the way other states do, so anything higher looks illegal.
What is actually true
The Colorado sections we read set no maximum at all. A Denver landlord can ask for any amount the lease states - your protection is the refund rules on the back end, not a ceiling on the front end.
Denver sits in the no cap column alongside Austin, Miami, Chicago, and Nashville, while Los Angeles and New York City hold landlords to one month's rent. What Colorado hands you instead is one of the sharper penalties on this chart - withhold in bad faith here and it costs three times the money.
Plain English Version
Think of your deposit as a hold on a credit card, not a payment you've already made. The landlord can only convert it to a charge for real damage you caused, and has to give you the receipt in writing.
Security Deposit Forfeiture Example - What the Wording Looks Like in Denver, CO
The sample clause below is real lease language - a court quoted it word for word, and then ruled on it. What the judge decided is at the bottom of this block.
Find the equivalent paragraph in your own lease and read the two side by side. The wording will differ; the moving parts rarely do.
If Tenant vacates prior to the Expiration Date (as extended, if applicable), the security deposit shall be forfeited and Tenant shall be obligated for rent payments for the remainder of the term, or until the Property has been re-rented whichever is less.
Quoted from the published opinion in Cromar v. TAG Realty, LLC, No. 87780-1-I (Wash. Ct. App. Div. I, 2026). Judicial opinions are not subject to copyright; the lease language is reproduced in limited part for commentary under 17 U.S.C. § 107.
“vacates prior to the Expiration Date”
Colorado's refund clock runs 30 days from the lease ending or from you surrendering the premises - unless your lease sets a longer period, which many do. Check yours, because that is one of the few deposit terms a Colorado lease can lengthen.
“(as extended, if applicable)”
Four words that can move your whole timeline. If the term was extended, “early” means something different from what you signed for - and the deposit deadline runs from the real end date, not the original one.
“shall be forfeited and Tenant shall be obligated for rent payments”
Colorado's answer to a blanket forfeiture is procedural and it is effective. To keep any of it the landlord must give a written statement listing the exact reasons - and “the lease says forfeited” is not a reason, it is a restatement of the clause.
“until the Property has been re-rented whichever is less”
This limb is the one to hold a landlord to. Ask when the unit was re-let, and ask in writing. It is the date that stops the rent claim, and it is a fact the landlord already knows.
Held unlawful, and the tenants were awarded double damages. They broke the lease early to buy a home. The landlord issued a move-out statement headed “EARLY TERMINATION SECURITY DEPOSIT FORFEIT” and told them no refund was due. The court held the forfeiture clause could not override the statute governing what a landlord may actually keep.
One court, one lease, one state. That answer is not automatically yours, and your lease may be worded to land differently. Use this to know what to look for and what to ask - your state's tenant hotline or a local tenant attorney can answer it for your document.
Colorado Law on Security Deposit Rules
- Colorado places no limit on how large a security deposit can be.
- The deposit is due back within 30 days of the lease ending or the tenant surrendering the premises, unless the lease sets a longer period capped at 60 days.
- Keeping any portion requires a written statement listing the exact reasons.
- Wrongful retention of a deposit exposes the landlord to treble the portion wrongfully withheld plus reasonable attorney fees and court costs, and the tenant must first notify the landlord of the demand and of the intent to sue at least seven days before filing. HB25-1249 added a definition of bad faith: an amount that unreasonably exceeds the actual damages the landlord incurred, is retained without actual cause, is one the landlord knew or should have known exceeded actual damages, or is retained solely or in part for an unlawful, retaliatory or discriminatory purpose. An amount is presumed to unreasonably exceed actual damages if it is 125 percent or more of the damages incurred, and in a tenant's court action the landlord bears the burden of proving the amount of actual damages.
- Read HB25-1249 for what it did and did not change. The bar on keeping a deposit for normal wear and tear was already law before it. What the act added, effective January 1, 2026 and applying to conduct on or after that date, is a bar on retaining a deposit "for any damage or defective condition that preexisted the tenancy", and a wider definition of "normal wear and tear" at C.R.S. 38-12-102(4), which now reads "deterioration, damage, or uncleanliness" arising from the use a unit is intended for "or reasonably and typically used".
- Two rights the same act gives a tenant at move-out. On either party's request, where reasonable and practicable, the landlord and tenant must conduct a walk-through inspection, in person or by an interactive telecommunication walk-through, to identify in writing any damage or defective conditions beyond normal wear and tear that did not preexist the tenancy. And within 14 days of a tenant's written request the landlord must hand over the documentation it holds - photographs, inspection forms or reports, receipts, invoices or estimates - relevant to what it kept.

Colorado's rule under C.R.S. § 38-12-103 is short. There's no ceiling on the amount, the deposit is due back within 30 days of the lease ending or you surrendering the unit, and every deduction needs a written statement of the exact reasons. A lease can stretch that clock, but the statute caps the stretch at 60 days.
Compare that to Seattle, where the city limits the deposit plus move-in fees to one month's rent combined and lets renters pay it in installments. Colorado gives you nothing on the front end - but from January 1, 2026, HB25-1249 blocks deductions for normal wear and tear and treats keeping 125% or more of actual damages as bad faith.
Colorado Tenant Protections
Your deposit must come back within 30 days of the lease ending, or within whatever longer window the lease names, which can never exceed 60 days. Keeping any portion requires a written statement listing the exact reasons for each deduction. Wrongful retention exposes the landlord to three times the amount wrongfully withheld plus attorney fees and court costs; since HB25-1249 the tenant must first notify the landlord of the demand and of the intent to sue at least seven days before filing.
What's Specific to Denver
Figures are the state rule, or the stronger city ordinance where one exists. Verify the current law for your own situation before relying on it.
Denver adds nothing on deposits that our Colorado record found: no municipal security deposit ordinance here, so C.R.S. § 38-12-103 governs the amount, the deadline, and the deductions. Chicago renters get a city ordinance forcing separate interest-bearing accounts; Denver renters get the state statute.
That gap shows up fast in a market where large management companies price deposits off your credit score and stack pet deposits and admin fees on top. Since our Colorado record finds no cap on the total move-in cost, read that line item by item before you sign, and check whether your lease quietly uses the 60-day return window instead of 30.
It should name 30 days or a specific longer period. Colorado caps that longer period at 60 days, so anything past that isn't enforceable.
The Colorado sections we read don't require one, but a fair rental agreement includes it. Without a signed baseline, a move-out dispute is your word against theirs.
Red flag. Your landlord still owes a written itemized statement for anything kept, and a label in the lease doesn't override the statute.
Red flag. Flat cleaning charges applied regardless of condition collide with the January 1, 2026 ban on wear-and-tear deductions.

Red Flags to Watch Out For
-
Deposit called nonrefundable
A blanket nonrefundable label doesn't erase the duty to return what you don't owe. Colorado still requires a written statement of every single deduction.
-
Sixty-day clause buried in fine print
A lease can legally stretch the refund window to 60 days instead of 30. It's almost never highlighted, so search the document for the number.
-
Automatic cleaning and carpet fees
Flat move-out charges billed no matter how you leave the place. Colorado bars deductions for normal wear and tear, and since January 1, 2026 for damage that preexisted your tenancy too.
-
Cash deposit with no receipt
With no written proof of what you paid, you'll be arguing about the amount before you ever get to argue about the deductions. Get it in writing.
-
Deductions at landlord's discretion
Language that lets the landlord decide charges without explaining them conflicts with the statute. Every deduction needs an itemized written reason tied to actual damage.
Your Rights as a Denver Tenant
-
A hard refund deadline
Your deposit is due back within 30 days, or the longer period your lease names, which can never run past 60 days.
-
An itemized written statement
Every dollar kept needs a written reason stating the exact basis. A vague lump-sum damages deduction doesn't satisfy C.R.S. § 38-12-103.
-
Triple damages for bad-faith withholding
A landlord who wrongfully keeps money owes three times the wrongfully withheld amount plus attorney fees and court costs.
-
No charge for normal wear
Wear-and-tear deductions are barred, and since January 1, 2026 keeping 125% or more of actual damages is presumed to unreasonably exceed them, with the landlord carrying the burden of proving those damages.
What To Do - Step by Step
Photograph the unit on day one
Walk every room with your phone before you unpack and email the photos to your property manager. Our Colorado record finds no move-in checklist mandate, so your photos may be the only evidence of the unit's condition at move-in.
Find your return deadline
Locate the sentence that says 30 days or names a longer window. That number is the date your landlord becomes officially late.
Send written notice and address
Give your move-out notice and forwarding address in writing and keep the timestamp. It removes the "we had nowhere to send it" excuse before it's used.
Document the empty unit
Shoot timestamped photos and a slow video of every surface after the last box is out. Compare it against your move-in set before you hand over the keys.
Send a written demand
Once the deadline passes, email a demand naming the amount and the date it was due. Cite C.R.S. § 38-12-103 and the three times damages exposure.
File in Denver County Court
