Colorado’s security deposit rules changed in important ways in 2026. If you rent a home or apartment in Colorado, understanding the current rules can help you avoid losing money unnecessarily and can help landlords handle deposits correctly.
This guide explains Colorado security deposit law as it applies in 2026, including the statewide deposit limit, the deadline for returning a deposit, deductions for damage, and new rules addressing pre-existing conditions and bad-faith withholding.
How Much Can a Landlord Charge for a Security Deposit in Colorado?
Colorado law generally prohibits a residential landlord from requiring a security deposit greater than two monthly rent payments under the rental agreement.
There is an important future exception. A 2026 law creates an exception beginning January 1, 2027 for certain post-closing occupancy agreements connected with a purchase of residential property. For an ordinary residential rental in September 2026, the two-month limit remains the general rule.
When Must a Colorado Landlord Return a Security Deposit?
For leases ending in 2026, Colorado law generally requires the landlord to return the security deposit within 30 days after the lease terminates or the tenant surrenders the premises, whichever occurs later.
The lease may provide for a longer period, but the period cannot exceed 60 days. This means tenants should check the security-deposit section of their lease instead of assuming that every landlord has exactly the same deadline.
If the landlord keeps part of the deposit, the landlord must provide the tenant with a written statement explaining the reasons for the retention and return the remaining amount.
Can a Colorado Landlord Keep a Deposit for Normal Wear and Tear?
No. Colorado law does not allow a landlord to keep a security deposit simply because a rental unit shows ordinary wear and tear.
Normal wear and tear is different from damage caused by a tenant’s unreasonable or negligent conduct. For example, ordinary aging of a rental unit is not automatically the same thing as damage that requires the tenant to pay for repairs.
Colorado’s 2026 rules also state that a landlord cannot retain a security deposit for damage or a defective condition that preexisted the tenancy. This makes move-in documentation especially important.
What Can a Landlord Deduct From a Colorado Security Deposit?
A landlord can generally make lawful deductions for amounts the tenant is responsible for under the rental agreement and applicable law. Depending on the circumstances, this can include unpaid rent, certain utility charges, and reasonable costs associated with damage beyond normal wear and tear.
Colorado’s 2026 protections also address bad-faith withholding. A landlord may be found to have retained a deposit in bad faith when the amount retained unreasonably exceeds actual damages, when there is no actual cause for the retention, when the landlord knew or should have known the amount exceeded actual damages, or when the retention is for an unlawful, retaliatory, or discriminatory purpose.
What Is the 125% Rule for Colorado Security Deposits?
One of Colorado’s newer protections creates a presumption that a landlord has retained an unreasonable amount when the amount withheld is 125% or more of the actual damages incurred.
This does not mean a tenant automatically wins a lawsuit whenever a landlord withholds more than 125% of a claimed repair cost. It is a statutory presumption that can affect a dispute and the landlord’s burden of proving the amount of actual damages.
What Should Tenants Do Before Moving Into a Colorado Rental?
Because Colorado now specifically addresses pre-existing damage, tenants should create a detailed record at the beginning of the tenancy.
- Take clear photographs and video of each room before moving furniture in.
- Photograph floors, walls, appliances, windows, doors, fixtures, and bathrooms.
- Write down existing stains, scratches, dents, broken items, or other defects.
- Complete the landlord’s move-in inspection form if one is provided.
- Keep copies of emails or messages reporting pre-existing problems.
- Store the photographs and documents somewhere safe until after the tenancy ends.
A good move-in record can be extremely valuable if a landlord later claims that the tenant caused damage that was already present.
What Should Tenants Do When Moving Out?
Before leaving, clean the property according to the lease, remove personal belongings, complete agreed repairs when appropriate, and take another set of dated photographs or video.
Give the landlord a forwarding address and keep proof that you provided it. If the landlord sends a written list of deductions, compare each deduction with your move-in and move-out evidence.
What If a Landlord Wrongfully Withholds a Colorado Security Deposit?
If you believe your landlord withheld money unlawfully, first request an explanation and supporting documentation in writing. Compare the claimed deductions with the lease, your photographs, receipts, inspection records, and the condition of the property.
Colorado law can provide remedies when a deposit is wrongfully withheld. The exact remedy depends on the facts and the statutory requirements, so tenants should not assume that every disagreement over a deduction automatically creates a claim for a specific amount of damages.
If a substantial amount of money is involved, consider speaking with a Colorado attorney or a qualified legal-aid organization before filing a court claim.
