Colorado security deposit laws for landlords: the two month cap, exact reasons and treble damages
Colorado caps a security deposit at two months' rent and requires you to return it within 30 days after the lease ends or the premises are surrendered, whichever is last, unless the lease sets a longer period of up to 60 days. Any amount you keep needs a written statement of the exact reasons, backed on request by documents. Wrongful retention carries treble damages for the part withheld, and amounts of 125 percent or more of actual damage are presumed unreasonable. The rules are in C.R.S. 38-12-102.5 and 38-12-103.
What is the Colorado deposit cap?
C.R.S. 38-12-102.5(1) says a landlord shall not require a tenant to submit a security deposit that exceeds the amount of two monthly rent payments under the rental agreement. A 2026 amendment (SB 26-054, effective August 12, 2026) adds an exception that starts January 1, 2027 for tenants who sold their home to the landlord and signed a post-closing occupancy agreement. For an ordinary rental the cap is two months.
How long do I have, and what can I keep?
Section 38-12-103(1)(a) says to return the full deposit within thirty days after the termination of a lease or surrender of the premises, whichever occurs last, unless the lease specifies a longer period that does not exceed sixty days. You may not keep any of it for normal wear and tear or for damage or a defective condition that existed before the tenancy. Actual cause to keep a reasonable amount exists only for nonpayment of rent, nonpayment of utility charges, nonpayment of other lawful charges listed in the lease, and necessary repair work for damage or defects that exceed normal wear and tear and did not preexist the tenancy.
When there is cause, you send a written statement listing the exact reasons, together with the difference between the deposit and the amount retained. You comply by sending the statement, payment and documentation to the tenant's last known address or to an email address you actually know, and you may pay by mailing a payment to the last known address or, with the tenant's consent, by a secured electronic transfer of funds.
What about carpet and paint?
Colorado is unusually specific. Subsection (11) says you do not have actual cause to keep any amount to replace carpet throughout a unit unless there is substantial and irreparable damage that exceeds normal wear and tear and did not preexist the tenancy, and you cannot treat carpet as substantially and irreparably damaged if it has not been replaced with new carpet within ten years before the lease ended. The same logic applies to painting the whole interior: only substantial damage to the paint of the walls and ceilings throughout the whole unit beyond normal wear and tear qualifies. Damage to a portion of the carpet or paint can still justify charging for that portion. These two rules do not apply to mobile home park rentals. A lease term charging a tenant for repairs or cleaning due to normal wear and tear, or for preexisting conditions, is void (subsection (7)(b)).
Example a made-up tenant leaves after three years in a unit with seven year old carpet. A pet stain ruined one 8 by 10 foot section, which a flooring company replaces for $520. The rest is worn but sound. The landlord may keep $520, with the invoice and photos, but not the $2,900 to replace all the carpet. A full replacement claim would likely be treated as unreasonable.
What documents must I produce?
For leases ending or premises surrendered on or after January 1, 2026, subsection (8) says that if you provide the written statement within fourteen days after a written request from the tenant, you must provide documentation in your possession or control that is relevant to keeping the deposit: photographs, inspection forms or reports, receipts, invoices or estimates. Subsection (1.5) requires a walk-through inspection, in person or by an interactive video walk-through, at a tenant's request, if reasonable and practicable, before the lease ends and after the tenant has had the chance to remove furniture, to identify damage in writing.
What does wrongful withholding cost?
Under subsection (3)(a), wrongful retention makes a landlord liable for treble the amount of the portion wrongfully withheld, plus reasonable attorney fees and court costs. A tenant must first make a demand and give notice of intent to sue at least seven days before filing, and may sue only if the landlord does not return the money within those seven days. The landlord bears the burden of proving the withholding was not wrongful and that the section was followed. A landlord who fails to follow the section forfeits the right to withhold any portion (subsection (2)).
Retention is in bad faith when the amount unreasonably exceeds actual damages, has no actual cause, is an amount the landlord knew or should have known exceeded actual damages, or is for an unlawful, retaliatory or discriminatory purpose. An amount retained is presumed to unreasonably exceed actual damages when it is 125 percent or more of them. A landlord who keeps money in good faith, otherwise follows the section and is found to have kept too much owes only the excess and court costs.
Example a made-up landlord keeps $500 of a $2,000 deposit for wall repairs that cost $380 in real invoices. $500 is 132 percent of $380, so it is presumed unreasonable. If the court treats the extra $120 as wrongfully withheld in bad faith, treble the $120 is $360, plus fees and costs. A landlord who honestly estimated, complied with every step and was just wrong would owe only the $120 excess and costs.
What if the building sells, or the refund bounces back?
When your interest ends by sale, assignment, death, a receiver or otherwise, subsection (4) gives whoever holds the deposits sixty days to transfer them (or any remainder after lawful deductions) to the successor and notify each tenant by mail, or to return them to the tenant; the successor then has a landlord's rights and duties for those funds. If a refund payment comes back after you mail it, hold it for at least one year and pay it out within fifteen calendar days of the tenant's request (subsection (9)).
How DoorKeeping handles it
DoorKeeping keeps a property's inspection photos, invoices and signed leases as documents tied to that property, and the deposit for each tenant is a line in the property's own books. That is the pile you pull from when a tenant asks for documentation. Money paths wait for your one tap; the deposit stays in your bank account. DoorKeeping gives no legal advice.
