Renter guide
The lease matters, but it is not the whole rulebook. Colorado law sets limits on late fees and rent increases, response times for uninhabitable conditions, deposit-return rules, and the grounds for ending many tenancies. Your city or county may add housing codes, rental rules, or a local complaint process.
The ordinary state rules
Rent must be at least seven calendar days late before a late fee may be charged.
The fee cannot exceed the greater of $50 or 5% of the past-due rent. It must be disclosed in the rental agreement, and it may be charged only once for that late payment.
A residential landlord may not increase rent more than once in any 12-month period of the tenancy.
When there is no written rental agreement, state law calls for 60 days of notice before an increase. A written lease and local law may add other rules.
Colorado sets a 24-hour or 72-hour clock for starting work after notice of an uninhabitable condition.
The 24-hour clock applies when the condition materially interferes with life, health, or safety. Other uninhabitable conditions use 72 hours. The current statute says remedial action continues until the condition is repaired.
The ordinary return deadline is one month after the lease ends or the home is surrendered and accepted.
A lease may set a longer period, but not more than 60 days. Any amount kept needs exact written reasons. Normal wear and preexisting damage are not valid deductions.
The practical path
Check rent, fees, utilities, guests, pets, repairs, notice addresses, renewal, and move-out terms. Then check the official city and county pages for rules tied to the address.
Take clear, dated photos or video before unpacking. Write down stains, marks, broken items, and other existing problems. Send the checklist through a saved written channel and keep the original.
Save the signed lease and add-ons, payment records, receipts, emails, letters, notices, and portal messages. Take screenshots if a portal does not give you a copy.
Use the address, email, or portal listed in the lease. Name the problem, room, date noticed, and effect on the home. Add photos, ask for a written reply, and save proof that the report was sent.
Get legal help before you hold back rent, take a repair bill out of rent, or move out early. A summons, complaint, or hearing notice starts court work. Follow the dates printed on the papers.
Repairs and habitability
A phone call may get a quick response, but it is hard to prove later. Send a written notice through the lease's listed channel. If you also call, write down when you called and who spoke with you.
Once the landlord has notice, state law calls for remedial action to start within 24 hours when the condition materially interferes with life, health, or safety. Other uninhabitable conditions use a 72-hour start. Starting is not the finish line. The current statute says remedial action continues until the condition is repaired.
Say where it is, when you first saw it, and how it affects the home. Add clear photos or video when they help.
Ask when someone will inspect or repair it. Give safe ways to arrange access, and keep the reply.
Save proof that the notice was sent. Keep later messages, entry notices, work records, and new photos if the condition changes.
Colorado habitability remedies use specific notice, proof, and follow-up steps. The right step can change with the condition, the lease, and any court case. Use the current statutes and court forms, then get legal help before changing rent payments or ending the lease.
Security deposits
The ordinary return deadline is one month after the lease ends or the home is surrendered and accepted, whichever happens later. A lease may set a longer period, but not more than 60 days. If a landlord keeps part of the deposit, the written statement must give exact reasons and the balance must be returned. Preexisting damage and normal wear are not reasons to keep the deposit.
Record anything that was already worn, marked, damaged, or not working.
Either side may ask for a walk-through. When it is reasonable and practical, it should happen at a mutually convenient time after furniture can be removed and before the lease ends or the home is surrendered. Take final photos, return keys as directed, and give a forwarding address.
Match the written statement to your records. Ask for related documents in writing. Check the current law and get legal help if the numbers do not line up.
Count from the event named in the law, not just the day you carried out the last box. Keep proof of the lease end, surrender, key return, forwarding address, statement, and payment.
Where to get help
Start with the lease's notice channel. If the problem goes on, check the official city or county site. Look for housing, building code, health, rental license, or code help. Ask which office serves the exact address.
Do not ignore a summons, complaint, or hearing notice. Mark the hearing date and any date to file an answer. The Colorado Judicial Branch has the current answer form and court steps. A court self-help center or a Colorado landlord-tenant lawyer can help you work through the papers.
If you think the landlord skipped the court process, use the official Judicial Branch page. Its unlawful-evictions page explains a different case and forms. Read the current page and get legal help soon.
Colorado housing law lists traits that are protected from bias. One is source of income. The state poster names the full list. It also explains disability help. The Colorado Civil Rights Division poster tells you how to contact the state. Time limits apply, so reach out soon.
FAQ
Do not simply skip the payment. Colorado law has repair-and-deduct and other remedies in some situations, but they use exact notice, waiting, proof, and contractor steps. Keep reporting the problem in writing and get legal help before withholding rent, deducting a repair, or ending the lease.
The ordinary state deadline is one month after the lease ends or the home is surrendered and accepted, whichever is later. The lease may name a longer period, but not more than 60 days. If money is kept, the landlord must give exact written reasons and return the balance.
Read the move-out part of the lease. Ask in writing about a walk-through, take dated photos after your things are out, return the keys as directed, give a forwarding address, and keep proof of each step.
Save the statement and payment. Compare each item with the lease, move-in record, move-out photos, and current law. Ask for the related records in writing. HB25-1249 added documentation and walk-through protections, so use the current law and get legal help if the numbers still do not line up.
No. State law says the rent must be at least seven calendar days late. The fee cannot exceed the greater of $50 or 5% of the past-due rent, must be disclosed in the rental agreement, and cannot be charged more than once for the same late payment.
Colorado generally requires cause, with exceptions. State law recognizes tenant-fault grounds and limited no-fault grounds, such as some sales, owner or family occupancy, demolition, and substantial repairs. The exact notice and proof depend on the ground and the tenancy.
Read every page now. Find the court, case number, hearing date, and any date to file an answer. Then open the current tenant forms on the Colorado Judicial Branch residential-evictions page. Get legal help quickly if you can.
The Colorado Judicial Branch has a separate unlawful-evictions page for cases in which the proper process was not followed. Use its current instructions and seek legal help promptly.
Start with the Colorado Civil Rights Division housing poster. It lists protected traits, explains disability accommodations, and gives complaint contact information. Filing limits apply, so contact the division promptly.
