If you signed a lease in Denver or anywhere else in Colorado after January 1, 2026, your landlord legally cannot ask you for more than one month's rent as a security deposit. That is new. Before 2026, the cap was two months. And there is more — Colorado now gives you the legal right to pay that deposit in monthly installments spread over six months, so you no longer have to come up with a full month's rent upfront just to get your keys.

Colorado has been on a significant legislative run when it comes to tenant protections. The state passed cause-based eviction requirements in 2024, capped late fees, required rent price transparency, and then in 2026 passed one of the most renter-friendly security deposit overhauls in the country. If you are a Colorado renter and your understanding of tenant law is more than a year old, there is a good chance you are operating with outdated information.

This guide covers the full picture — what changed in 2026, what has been in place since 2024, and what every Colorado renter should have memorized before signing or renewing a lease.

⚖️ Colorado Law — C.R.S. Title 38

Colorado's landlord-tenant law sits primarily in C.R.S. Title 38. Key sections: C.R.S. 38-12-103 (security deposits), C.R.S. 38-12-503 (implied warranty of habitability), C.R.S. 38-12-301 (rent control preemption), C.R.S. 13-40-104 (eviction notice). HB24-1098 added cause-based eviction. HB25-1249 overhauled security deposit rules effective January 1, 2026.

The 2026 Security Deposit Overhaul — HB25-1249

Colorado's new security deposit law is one of the most significant changes to renter rights in the state in a generation. Here is what it actually means for you, explained practically.

The New 1-Month Cap

Starting January 1, 2026, Colorado landlords cannot collect a refundable security deposit of more than one month's rent. Previously, the cap was two months. If you signed a lease after January 1, 2026 and your landlord asked for two months as a deposit, that excess is likely not legally enforceable.

For existing leases signed before January 1, 2026, the old rules still apply to whatever deposit was already collected. But if your lease renews after that date, the new cap applies to any renewal.

The Right to Pay in Installments — Brand New

This is the change that surprised most Colorado renters — because it is genuinely new and genuinely helpful. Under HB25-1249, you now have the legal right to pay your security deposit in monthly installments over the first six months of your tenancy. That means if your monthly rent is $1,800 and the deposit is $1,800, instead of paying that full amount upfront, you can pay $300 a month for six months alongside your regular rent.

Landlords cannot refuse to rent to you solely because you want to use the installment option. This right cannot be waived in a lease. It is a hard-won protection designed specifically to make housing more accessible for renters who cannot afford a large lump-sum deposit at move-in.

Using the installment option: Tell your prospective landlord before signing that you want to pay your deposit in monthly installments under HB25-1249. Get the installment schedule in writing as part of your lease or a signed addendum. Keep records of each payment.

Deposits Are Now Legally "Your Money"

HB25-1249 makes explicit something that was previously implied: security deposits are legally classified as tenant money held in trust by the landlord. They are not the landlord's money. They cannot be spent or co-mingled with the landlord's operating funds. If a landlord goes bankrupt or sells the property, your deposit should be protected as tenant property — not treated as the landlord's asset.

The Joint Move-Out Inspection Right

Before you move out, you now have the right to request a joint walk-through inspection with your landlord. Your landlord must conduct this inspection at a mutually convenient time — in person or virtually — and document any damage they intend to claim beyond normal wear and tear. Here is the critical part: if a landlord tries to charge you for damage that was not documented during this joint inspection, they may not be able to. The inspection requirement is designed to eliminate the "we found damage after you left" surprise.

Always request the joint inspection. Email your landlord before your move-out date asking to schedule a joint inspection under HB25-1249. This creates a paper trail, forces the landlord to document issues in your presence, and protects you from post-departure damage claims that were never identified while you were there to dispute them.

The 30-Day Return Deadline — Now Strict

Previously, Colorado law said deposits had to be returned within "one month" — which was technically ambiguous about whether that meant 30 or 31 days depending on the month. HB25-1249 clarified this: the deadline is exactly 30 days from the date your lease terminates and you vacate. Your lease can specify a longer period, but it cannot exceed 60 days.

🚩 Miss the deadline and pay triple. Under C.R.S. 38-12-103, if your Colorado landlord wrongfully withholds your deposit or misses the return deadline, you can sue for three times the wrongfully withheld amount plus attorney fees. Colorado courts enforce this. Also: if a landlord retains 125% or more of the actual cost of damages, they are presumed to have acted in bad faith — making the triple damages claim even stronger.

Cause-Based Eviction — HB24-1098

This one has been in effect since 2024, but many Colorado renters still do not know about it. Under HB24-1098, landlords must have a legally valid reason to evict a tenant or refuse to renew a lease once a tenant has established residency. This is called cause-based or just-cause eviction.

Valid causes for eviction or non-renewal include non-payment of rent, serious lease violations, the owner intending to move in, demolition or major renovation, or the landlord taking the unit off the rental market. What landlords cannot do is refuse to renew your lease simply because they want to find a new tenant willing to pay higher rent. That practice — sometimes called "renoviction" — is now a legally prohibited basis for non-renewal in Colorado.

Eviction Notice Periods

For non-payment of rent, your landlord must give you 10 days written notice to pay or vacate. For lease violations, the notice period depends on the severity. For non-renewal of a lease without cause, the notice required depends on how long you have lived there:

These are substantial notice periods — especially the 91-day requirement for long-term tenants, which gives you almost three months to find new housing when a landlord exercises a valid cause for non-renewal.

🚩 Self-Help Eviction is Illegal. Colorado landlords cannot change your locks, remove your belongings, shut off utilities, or physically remove you without a court order. Doing so violates C.R.S. 38-12-510 and entitles you to remain in possession, actual damages, and potentially punitive damages. If this happens, call the police and contact Colorado Legal Services immediately.

Late Fee Cap and Rent Transparency

Colorado caps late fees at the greater of $50 or 5% of the monthly rent. If your rent is $1,500, the maximum late fee is $75. If your rent is $800, the maximum is $50. Any late fee in your lease above this amount is unenforceable — you do not have to pay the excess, and you can dispute it.

Under HB25-1090, also effective in 2026, landlords are now required to disclose the full rental price upfront — including all mandatory fees. This means the listed rent must include every charge you are required to pay as part of your tenancy, not just the base rent. "Junk fees" that appear after you have agreed to rent are now prohibited.

Right to a Habitable Home

Colorado's implied warranty of habitability under C.R.S. 38-12-503 requires landlords to maintain your rental in a condition fit for human habitation throughout the entire tenancy. This includes working heat, working plumbing with hot water, structural soundness, working electrical systems, and freedom from serious pest infestations.

If your landlord fails to make required repairs after written notice, Colorado gives you several remedies: you can repair and deduct the cost from rent, withhold rent until repairs are made, or terminate the lease if conditions are severe enough. If you are a tenant receiving certain government benefits, landlords with more than five units may be required to attempt mediation before proceeding with eviction — at no cost to you.

No Rent Control in Colorado

Colorado prohibits cities and counties from enacting rent control on private residential property under C.R.S. 38-12-301. Landlords can raise rent by any amount. However, rent can only be increased once per 12-month period — landlords cannot make multiple increases within a single year. Boulder has limited mobile home park rent stabilization, but this does not apply to standard apartments or houses.

Check your lease for the entry notice clause and hold your landlord to it.
