Colorado Eviction Process 2026 — JBITS Notice Explained

Colorado expanded its non-payment notice period from 3 days to 10 days, added warranty-of-habitability protections with real teeth, and ramped up just-cause requirements for many tenancies. The state's old reputation as a fast eviction jurisdiction does not match 2026 reality. Below: the current notice rules, the FED process in County Court, and the procedural traps that slow landlords down.

If you operate residential rentals in Colorado, the Forcible Entry and Detainer statute (C.R.S. § 13-40-101 et seq.) and the Warranty of Habitability statute (C.R.S. § 38-12-501 et seq.) together set your operating rules. The "Jeanette Bonafonte In The State" reforms — sometimes referenced as JBITS in industry shorthand — represent a multi-year shift toward tenant protections that landlords coming from Texas or Arizona will find unfamiliar. Here is the 2026 playbook.

The 10-day notice replaced the 3-day notice

Colorado expanded the demand-for-rent notice period from 3 days to 10 days under HB 21-1121. The 10-Day Notice to Pay Rent or Quit is now the standard pre-suit notice for non-payment of rent in residential cases. The notice must:

• Demand payment of the rent owed within 10 days of service OR vacancy of the premises
• Identify the rent owed by month or period
• Be in writing
• Comply with C.R.S. § 13-40-104 for service

The 10 days are counted starting the day after service. The expansion from 3 to 10 days substantially changes the operator math: a tenant who is intermittently late has more runway to cure before you can file, and the timeline from default to lockout has stretched accordingly.

For owners of single-family homes or duplexes operating without a property manager, a shorter notice period (sometimes 5 days) may apply under specific exemptions. The default for most residential operators with multiple units is 10 days.

Service of the 10-day notice

Acceptable service under C.R.S. § 13-40-108 includes:

1. Personal delivery to the tenant
2. Leaving with a family member of suitable age at the residence
3. Posting on a conspicuous part of the premises if neither (1) nor (2) is practicable

Posting alone is acceptable in Colorado if personal and substituted service are not practicable, but the safer practice — and the one that survives a contested service hearing — is to post AND mail by first-class mail to the tenant at the premises. Document the service date, method, and photo of the posted notice.

A defective notice means the FED is dismissed and you start over at day one. Tenant-side defenses in Denver, Boulder, and other Front Range courts increasingly include challenges to service. Build a service log into your workflow.

Just-cause termination for many tenancies

Colorado's HB 23-1171 added just-cause termination protections for residential tenancies in covered units. For tenancies covered by the law, you cannot terminate or non-renew without one of the enumerated grounds. Grounds include non-payment of rent, material breach, nuisance, illegal use, owner move-in (with notice and reletting restrictions), substantial rehabilitation, and several others.

The just-cause coverage is broad. Exemptions exist for certain owner-occupied properties, short-term rentals, employer-provided housing, and some other narrow categories. If you operate market-rate apartments in any Colorado city, plan that just-cause applies.

This is a different operating regime than Colorado had pre-2024. "Lease is up and I want them out" is no longer a complete answer. Document the ground, give the right notice, and follow the procedure for the ground you are asserting.

Warranty of habitability — the defense that delays cases

C.R.S. § 38-12-501 et seq. expanded the warranty of habitability in Colorado and gave tenants procedural tools that didn't exist a few years ago. A tenant facing eviction for non-payment can defend by asserting that the landlord failed to maintain the unit in habitable condition. The defense:

• Requires the tenant to have given the landlord written notice of the condition
• Requires the landlord to have failed to remedy within a statutory period (typically 24-96 hours for emergencies, longer for non-emergency repairs)
• Can result in rent abatement, repair-and-deduct remedies, or termination of the lease by the tenant
• In an FED, can offset rent owed and complicate the non-payment claim

Operators with neglected maintenance pipelines face a sharper risk in Colorado than in many other states. The warranty defense has real teeth — judges have abated rent significantly when tenants document persistent landlord failures.

Practical hygiene: respond to maintenance requests in writing within a defined SLA (24 hours for emergencies, 72 hours for non-emergencies is a defensible standard), keep service records, and follow up to confirm completion. Software that timestamps requests, dispatches work orders, and stores completion notes — the kind of work-order infrastructure Proprietio includes — is the documentary record that turns the warranty defense into a non-starter.

Filing the FED in County Court

Once the 10-day window expires without payment or vacancy, file the FED complaint in the County Court of the county where the property is located. Filing fees vary; typical range is $80–$120. The court schedules a return date — generally 7 to 14 days from filing.

A clean FED in Colorado now typically resolves in 5 to 9 weeks from notice to lockout. Contested cases run 8 to 14 weeks. Compared to the pre-2021 cycle, this is materially slower.

Mediation requirements and the eviction diversion program

Several Colorado jurisdictions, particularly Denver County, run mediation programs that are either mandatory or strongly encouraged before an eviction can proceed to trial. Funding from state-level Eviction Legal Defense Fund grants and right-to-counsel pilots has expanded tenant representation.

For landlords, the operational consequence is that you should expect a mediation appearance and possibly a consent agreement with a payment plan for tenants who can cure. Plan to bring the lease, a clean ledger, and evidence of any notice and service. Mediated outcomes often produce stipulations for possession contingent on a payment schedule — the tenant stays if they pay according to the schedule and you proceed to lockout if they don't.

A clean ledger is the single most important document in mediation. If your tracking is inconsistent — late fees applied differently from month to month, payments unallocated, charges for things not in the lease — the mediator will side with the tenant on the disputed line items.

Security deposit basics

Colorado caps the timeline for deposit returns under C.R.S. § 38-12-103:

• Within one month after termination of the lease or surrender of the premises (whichever is later), the landlord must return the deposit minus itemized deductions
• A longer return period (up to 60 days) is permitted if the lease specifically provides for it
• The itemization must be a written statement listing the deductions

Colorado does not statutorily cap the amount of the security deposit. Operators are free to charge what the market will bear, but excessive deposits invite a fair-housing-style challenge.

Failure to return the deposit on time, or to provide itemization, exposes the landlord to recovery of the wrongfully withheld portion plus, in certain cases, treble damages and attorney's fees under § 38-12-103(3).

FAQ

Is Colorado still a 3-day notice state? No. The non-payment notice period was expanded to 10 days under HB 21-1121. The 3-day notice survives for some narrow grounds (substantial damage, illegal acts) but is no longer the standard for non-payment of rent.

Does just-cause termination apply to my Colorado property? For most market-rate residential rentals, yes. HB 23-1171 expanded just-cause coverage. There are exemptions (certain owner-occupied properties, short-term rentals, employer housing), but the default for typical 5–200-door operators is that just-cause applies.

How long does an eviction take in Colorado now? A clean, uncontested non-payment case typically runs 5 to 9 weeks from notice to lockout. Contested cases with active tenant defenses run 8 to 14 weeks. Denver and Boulder run on the longer end.

Can a tenant raise habitability as a defense to non-payment? Yes, and the defense has teeth in Colorado after the 2019-2022 warranty-of-habitability reforms. The tenant must have given written notice of the condition and you must have failed to remedy within the statutory period. Document your maintenance response times.
