Colorado security deposit return
Colorado landlords must return a security deposit within 30 days after the later of lease termination or surrender of the premises; a lease may lengthen that period but not past 60 days. HB25-1249 rewrote the statute on January 1, 2026: a landlord may keep the deposit only for four listed reasons, may never charge for normal wear and tear or for damage that predated the tenancy, and now faces new carpet, paint, walk-through, and documentation rules. The deposit cap is two months’ rent. Wrongfully withholding the deposit exposes a landlord to treble damages plus attorney fees and court costs, but only after the tenant demands the deposit back, gives notice of intent to sue, and the landlord fails to return the money within seven days. Boulder is the only Colorado city that adds a deposit-interest requirement.

Covers residential rentals in Colorado, including a mobile home in a mobile home park (which has a lower cap and a trust-account rule). HB25-1249 rewrote this statute effective January 1, 2026, so most of what other sites say about Colorado is now out of date.
The rules, with citations
Deadline to return or account
The landlord must return the full deposit, or send a written statement of the exact reasons for any retention, together with the balance, within 30 days after the later of lease termination or the landlord’s acceptance of surrender of the premises. A lease may set a longer period, but never more than 60 days. HB25-1249 changed the old "one month" to "thirty days."
Statute text & notes
A landlord shall, within thirty days after the termination of a lease or surrender and acceptance of a premises, whichever occurs last, return to the tenant the full security deposit deposited with the landlord by the tenant, unless the lease agreement specifies a longer period of time, but not to exceed sixty days.
The clock runs from the LATER of lease termination and the landlord accepting surrender of the premises, so do not compute from lease-end alone if you accepted the keys later. There is no forwarding-address condition (unlike some states): the deadline runs on its own. If day 30 lands on a weekend or a Colorado legal holiday, the law may extend it to the next business day (C.R.S. § 2-4-108(2)), but no Colorado court has applied that to this statute and missing the deadline forfeits your right to keep any of the deposit, so treat day 30 as the real target.
What you can deduct
A landlord has actual cause to keep money from the deposit only for four things: unpaid rent, unpaid utility charges, unpaid other lawful charges listed in the lease, and necessary repair work for damage or defective conditions that exceed normal wear and tear and did not predate the tenancy. Normal wear and tear, and any preexisting damage, may never be charged.
Statute text & notes
Except as provided in subsection (3.5)(a)(IV) of this section, a landlord has actual cause to retain reasonable amounts from the security deposit only for: (I) Nonpayment of rent; (II) Nonpayment of utility charges; (III) Nonpayment of other lawful charges listed in the lease; or (IV) Necessary repair work for damage or defective conditions that exceed normal wear and tear and did not preexist the tenancy.
This list is EXCLUSIVE ("only for"). HB25-1249 removed the old "abandonment of the premises" and "cleaning contracted for by the tenant" grounds, so an early-termination or cleaning charge must now fit one of the four categories, usually "other lawful charges listed in the lease." "Normal wear and tear" is now defined by statute and expressly includes ordinary damage and uncleanliness from typical use; it does not cover uncleanliness that leaves the unit substantially less clean than at move-in. Preexisting damage may never be charged, and a lease clause assigning normal-wear or preexisting-condition costs to the tenant is void (§ 103(7)(b)).
Carpet & paint limits
A landlord cannot use the deposit to re-carpet the whole unit unless there is substantial AND irreparable carpet damage beyond normal wear and tear that did not predate the tenancy, and carpet cannot be deemed substantially and irreparably damaged if it was not replaced with new carpet within the last ten years, which forecloses a replacement charge but not a charge to repair the specific damage. Whole-interior repainting requires substantial paint damage throughout the entire unit. The landlord may still charge for the damaged portion.
Statute text & notes
A landlord shall not deem carpet to be substantially and irreparably damaged if the carpet has not been replaced with new carpet within ten years preceding the termination of the lease or surrender of the premises.
Carpet: no whole-unit replacement charge unless the damage is substantial AND irreparable, and old carpet (not replaced in the last ten years) can’t be called substantially and irreparably damaged, which forecloses the replacement charge: you may still charge to repair the specific damaged portion. Paint: no whole-interior repaint charge unless there is substantial paint damage throughout the entire unit (there is no paint-age safe harbor). These limits do not apply to a mobile home in a mobile home park.
The walk-through inspection
Either party may ask for a walk-through inspection before the lease ends. If the tenant requests one, the landlord must provide it, at a mutually convenient time before termination or surrender and after the tenant has had a chance to remove furniture. The inspection identifies, in writing, damage beyond normal wear and tear that did not predate the tenancy. It can be done in person or by a live video walk-through.
Statute text & notes
Upon a landlord’s or tenant’s request, if reasonable and practicable, the landlord and tenant shall conduct a walk-through inspection, either in person or via a telecommunication-assisted interactive walk-through, of the dwelling unit to identify in writing any damage or defective conditions that are beyond normal wear and tear and that did not preexist the tenancy. The landlord shall provide a walk-through inspection at a tenant’s request, at a time that is mutually convenient to the parties, before the termination of the lease or the surrender of the premises, and after the tenant has had the opportunity to remove furniture.
This is new in 2026. Either party may request it, but the landlord’s duty to actually provide one is triggered by the TENANT’s request. A walk-through is strongly advisable: the written record is exactly the kind of documentation the tenant can later demand, but note the statute does not say damage left undocumented at the walk-through becomes un-chargeable (that consequence was proposed and removed before passage). It does not apply to a mobile home in a mobile home park.
Documentation on request (14 days)
For a move-out on or after January 1, 2026, if the tenant makes a written request, the landlord must hand over the documentation in its possession or control that is RELEVANT to keeping the deposit (photographs, inspection forms or reports, receipts, invoices, or estimates) within fourteen days. Relevant is not the same as helpful: a move-in photo, a walk-through form showing no damage, or an estimate you did not use is still relevant, and holding it back is what the statute treats as a failure to comply.
Statute text & notes
For a termination of a lease or a surrender of the premises on or after the effective date of this section, as amended, if a landlord provides a tenant with a written statement pursuant to subsection (1) of this section within fourteen days after a written request by the tenant, the landlord shall provide documentation in the landlord’s possession or control, including photographs, inspection forms or reports, receipts, invoices, or estimates, that is relevant to the retention of the tenant’s security deposit or any portion of the security deposit.
The duty is triggered by the tenant’s WRITTEN request; without one it is not engaged. There is no standalone fine, but failing to provide the documentation is one of the ways a withholding becomes "wrongful" (§ 103(2.5)(a)), which opens the door to forfeiture and treble. Read the 14-day window as running from the tenant’s written request.
The deposit cap
A Colorado landlord may not require a security deposit larger than two months’ rent. That amount took effect August 7, 2023 and neither 2026 act changed it. A 2026 amendment adds one narrow exception that starts January 1, 2027 and does not reach ordinary tenancies.
Statute text & notes
On and after August 7, 2023 except as described in subsection (2) of this section, a landlord shall not require a tenant to submit a security deposit in an amount that exceeds the amount of two monthly rent payments under the rental agreement.
The cap is two months’ rent. A widely-repeated claim that HB25-1249 cut it to one month is wrong: that provision was in the introduced bill and was removed before passage. "Rent" is not defined for this purpose, so our reading uses the base monthly rent under the lease. SB26-054 amended this section effective August 12, 2026 to add one narrow exception, and the exception itself does not begin until January 1, 2027. From that date the cap does not apply where the landlord and tenant have executed a post-closing occupancy agreement under a purchase contract by which the landlord bought the residence from the tenant. That is a seller rent-back rather than an ordinary tenancy, so two months is the answer for a normal rental both now and after that date.
Interest on the deposit
Colorado does not require landlords to pay interest on an ordinary residential security deposit. The only Colorado city that requires it is Boulder (see the city rules). Mobile-home-park deposits are held in a separate trust account, and the landlord keeps any interest earned as compensation.
Notes
No state statute requires deposit interest and none requires a separate or interest-bearing account for an ordinary residential deposit. The City of Boulder is the exception (B.R.C. ch. 12-2). Mobile-home-park deposits (§ 38-12-207) must sit in a separate trust account, but the interest there belongs to the landlord as administration compensation, not the tenant.
Mobile home in a park
For a mobile home in a mobile home park, the deposit rules combine: the park may charge no more than one month’s (lot) rent, the deposit stays the home owner’s property and must sit in a separate trust account with no commingling, and the § 103 return machine (30-day deadline, statement, treble) still applies, except the walk-through and carpet/paint rules do not.
Statute text & notes
The owner of a mobile home park or the owner’s agents may charge a security deposit in an amount not greater than one month’s rent.
A mobile home in a park is different from an ordinary rental in two ways: the cap is one month’s lot rent (not two), and the deposit must be held in a separate trust account as the home owner’s property (the landlord may keep the interest earned as compensation). Everything else: the 30-day return, the written statement, wrongful-withholding forfeiture and treble, still applies. The walk-through and carpet/paint limits do NOT apply here. A mobile home on private land (not in a park) is treated as an ordinary residential rental (two-month cap, full § 103).
Penalties for getting it wrong
Wrongfully keeping a deposit exposes a landlord to treble the amount wrongfully withheld, plus reasonable attorney fees and court costs. But the tenant must first demand the deposit back and give at least seven days’ notice, and the treble claim only lies if the landlord fails to return the money within those seven days. A landlord who acted in good faith and followed every requirement, but is found to have reasonably kept a bit too much, owes only the excess plus court costs: no treble, no fees.
Statute text & notes
The wrongful retention of a security deposit in violation of this section renders a landlord liable for treble the amount of that portion of the security deposit wrongfully withheld from the tenant, together with reasonable attorney fees and court costs; except that the tenant shall notify the landlord of the tenant’s demand for the return of the security deposit and intention to file legal proceedings at least seven days before filing the action.
HB25-1249 changed the old "willful" standard to "wrongful," which is now defined: a landlord is deemed to have wrongfully withheld by missing the statement/documentation, giving a vague statement, missing the deadline, or keeping money in bad faith (§ 103(2.5)). Bad faith is itself defined, and keeping 125% or more of actual damages is presumed unreasonable (§ 103(3.5)(b)). Three gates protect a compliant landlord: the treble claim requires (1) a wrongful withholding, (2) the tenant’s 7-day demand-and-notice with a failure to return in that window, and (3) it is displaced by the good-faith safe harbor (§ 103(3.5)(d)). If you acted in good faith, followed the rules, and simply return the money after a demand, no treble claim lies.
Normal wear and tear vs. damage
You can never keep any part of the deposit for normal wear and tear, and unlike some states, Colorado now defines the term by statute. HB25-1249 broadened it in 2026 to cover ordinary damage and uncleanliness from typical use. Here it is, verbatim:
"Normal wear and tear" means deterioration, damage, or uncleanliness that occurs, based upon the use for which a rental unit or mobile home space, as defined in section 38-12-201.5 (6.5), is intended or reasonably and typically used, without negligence, carelessness, accident, or abuse of the premises or equipment or private property by the tenant or home owner or members of the tenant’s or home owner’s household or their invitees or guests. "Normal wear and tear" does not include uncleanliness that renders a dwelling unit substantially less clean than the dwelling unit was when the lease began. C.R.S. § 38-12-102(4)
In plain terms: deterioration, damage, or uncleanliness from the unit being used the way it is meant to be used, without negligence or abuse, is not chargeable, but leaving the unit substantially less clean than at move-in is. Where the line commonly sits lives in the full guide: normal wear and tear vs. damage in Colorado. You decide what to claim, and a court decides any dispute.

Colorado security deposit: common questions
How long does a Colorado landlord have to return a security deposit?
Thirty days after the later of lease termination or surrender of the premises. A lease may set a longer period, but never more than sixty days. (HB25-1249 changed the old "one month" to "thirty days," effective January 1, 2026.) (C.R.S. § 38-12-103(1))
What can a Colorado landlord deduct from a security deposit?
Only four things: unpaid rent, unpaid utility charges, unpaid other lawful charges listed in the lease, and necessary repair of damage that exceeds normal wear and tear and did not predate the tenancy. Normal wear and tear and preexisting damage may never be charged. (C.R.S. § 38-12-103(1)(b))
How much can a Colorado landlord charge for a security deposit?
Two months’ rent. A widely repeated claim that a 2025 law cut it to one month is wrong: that provision was removed before the bill passed, so the cap is still two months. A refundable pet deposit of up to $300 is allowed on top. (C.R.S. § 38-12-102.5)
What is the penalty if a Colorado landlord wrongfully keeps a deposit?
Treble the amount wrongfully withheld, plus the tenant’s attorney fees and court costs, but only after the tenant demands the deposit back and gives notice of intent to sue, and the landlord fails to return the money within seven days. A good-faith, fully compliant landlord who merely kept a little too much owes only the excess plus court costs. (C.R.S. § 38-12-103(3), (3.5))
Does Colorado require interest on a security deposit?
State law does not, and the deposit sits in the landlord’s hands with no interest owed, except in the City of Boulder, which requires simple interest by local ordinance. Choose Boulder in the tool to compute it. (C.R.S. §§ 38-12-101 to 106; Boulder Rev. Code ch. 12-2)
Do the 2026 walk-through and carpet rules apply to a mobile home in a park?
No. For a mobile home in a mobile home park, the deposit cap is one month’s lot rent and the deposit must sit in a separate trust account, but the new walk-through inspection and the carpet and paint limits do not apply. Everything else (the 30-day deadline and the treble-damages rules) still does. (C.R.S. §§ 38-12-207, 38-12-103(12))
