1. Overview: Tenant Rights in Castle Pines

Castle Pines is a growing residential city in Douglas County, Colorado, incorporated in 2008. With a population of roughly 10,000 residents, it is primarily a single-family suburban community south of Denver. Renters in Castle Pines are governed entirely by Colorado state law — the city has enacted no local rent control, just-cause eviction, or tenant-protection ordinances beyond what the state requires.

Tenants most commonly ask about security deposit returns, their rights when a landlord wants them to move, and what to do if the unit is not properly maintained. Colorado's Warranty of Habitability Act, statewide just-cause eviction law, 91-day termination notice requirement, and security deposit cap all apply in Castle Pines and provide meaningful baseline protections.

This page summarizes the laws that apply to Castle Pines renters as of May 2026. It is provided for informational purposes only and does not constitute legal advice. Laws change frequently — consult a licensed Colorado attorney or a local legal aid organization for guidance specific to your situation.

2. Does Castle Pines Have Rent Control?

Castle Pines has no rent control ordinance, and there is no limit on how much a landlord may raise rent between lease terms. Colorado state law (C.R.S. § 38-12-301) prohibited local rent control until 2021, when SB 21-173 lifted the statewide preemption and allowed cities to enact their own ordinances. As of May 2026, no Colorado municipality — including Castle Pines — has enacted a rent-control ordinance since that change.

Landlords in Castle Pines may raise rent by any amount, provided they give proper advance written notice as required by lease terms or state law. Tenants who receive a rent increase they cannot afford may have the right to terminate with proper notice under C.R.S. § 13-40-107.

3. Colorado State Tenant Protections That Apply in Castle Pines

Several important Colorado state statutes protect renters in Castle Pines:

Security Deposit Cap (HB25-1249 / C.R.S. § 38-12-102.5): Effective January 1, 2026, landlords may not collect a security deposit exceeding one month's rent for unfurnished units. The deposit must be returned within 30 days of lease termination or surrender (or up to 60 days if the lease specifies), along with an itemized statement of any deductions. Wrongful withholding exposes the landlord to treble damages plus attorney fees (C.R.S. § 38-12-103).
Warranty of Habitability (C.R.S. § 38-12-501): Landlords must maintain rental units in a habitable condition, including functional heating, plumbing, electrical systems, and weatherproofing. If a landlord fails to address a serious violation after written notice, tenants may seek rent reduction, repair-and-deduct remedies, or lease termination.
91-Day Termination Notice (C.R.S. § 13-40-107): A landlord wishing to terminate a month-to-month tenancy must provide at least 91 days written notice — one of the longer notice periods in the country.
Just-Cause Eviction (HB24-1098 / C.R.S. § 13-40-107.5): Signed April 19, 2024, this law requires landlords to have a lawful reason — such as non-payment of rent, substantial lease violation, or no-fault reasons like demolition or owner move-in — before evicting a residential tenant or declining to renew a lease. No-fault evictions require at least 90 days notice and may require relocation assistance.
Anti-Retaliation (C.R.S. § 38-12-509): Landlords may not retaliate against tenants for reporting code violations, requesting repairs, or asserting other legal rights. Retaliatory acts include rent increases, eviction notices, or reductions in services.

4. Security Deposit Rules in Castle Pines

Under Colorado law, as amended by HB25-1249 effective January 1, 2026, security deposits in Castle Pines are subject to the following rules:

Cap: Landlords may not collect a security deposit exceeding one month's rent for standard unfurnished residential rentals (C.R.S. § 38-12-102.5). Pet deposits may not exceed 25% of the first month's rent.
Return deadline: The deposit must be returned within 30 days of lease termination or surrender of the premises. If the lease explicitly provides for a longer period, the deadline may extend up to 60 days — but no longer (C.R.S. § 38-12-103).
Itemized statement: Any deductions must be accompanied by a written, itemized statement. Landlords may not deduct for normal wear and tear or pre-existing damage.
Penalty for wrongful withholding: If a landlord wrongfully withholds any portion of the deposit, the tenant is entitled to treble (triple) damages plus reasonable attorney fees (C.R.S. § 38-12-103(3)).

5. Eviction Process and Your Rights in Castle Pines

Evictions in Castle Pines follow Colorado state law. Landlords must complete a formal legal process — self-help evictions (such as changing locks or shutting off utilities to force a tenant out) are strictly prohibited under Colorado law.

Just-Cause Requirement

Under HB24-1098 (C.R.S. § 13-40-107.5), effective April 2024, landlords must have lawful cause to evict or decline to renew a lease. Permissible grounds include:

Fault-based: Non-payment of rent; substantial lease violation (tenant has 10 days to cure); refusal to allow landlord entry after proper 72-hour notice; or a pattern of three or more late payments in a single tenancy.
No-fault: Demolition or conversion of the unit; substantial renovation requiring vacancy; landlord or immediate family member moving in; or withdrawal from the rental market for sale. No-fault evictions require at least 90 days written notice and may require the landlord to pay relocation assistance equal to two months' rent (plus one additional month if a minor, senior, or person with a disability resides in the unit).

Notice Requirements

Non-payment of rent: Written demand (3-day notice) to pay or vacate (C.R.S. § 13-40-104).
Lease violation: Written notice with 10 days to cure or vacate.
Month-to-month termination: At least 91 days written notice (C.R.S. § 13-40-107).

Court Process

If the tenant does not comply with the notice, the landlord must file an eviction (forcible entry and detainer) action in Douglas County Court. The tenant has the right to appear and contest the eviction. A judge must issue a judgment before any removal can occur. Tenants who believe the eviction is retaliatory or lacks just cause may raise those issues as an affirmative defense.

Frequently Asked Questions

Does Castle Pines have rent control?

No. Castle Pines has no rent control ordinance. Colorado law (C.R.S. § 38-12-301) prohibited local rent control until 2021, and no Colorado city has enacted an ordinance since the ban was lifted. Landlords in Castle Pines may charge any rent amount and raise rent between lease terms without restriction.

How much can my landlord raise my rent in Castle Pines?

There is no limit on rent increases in Castle Pines. A landlord may raise rent by any amount, but must provide proper advance written notice before a new rental period begins as required by the lease or state law. If you receive an unacceptable increase, you may be entitled to terminate your month-to-month tenancy with proper notice under C.R.S. § 13-40-107.

How long does my landlord have to return my security deposit in Castle Pines?

Under C.R.S. § 38-12-103 and as updated by HB25-1249 (effective January 1, 2026), your landlord must return your security deposit within 30 days of lease termination or surrender of the unit. If your lease specifies a longer period, it can extend up to 60 days but no more. If the landlord wrongfully withholds your deposit, you may be entitled to treble (triple) damages plus attorney fees.

What notice does my landlord need before evicting me in Castle Pines?

The notice required depends on the reason. For non-payment of rent, a 3-day written demand is required (C.R.S. § 13-40-104). For lease violations, tenants get 10 days to cure. For month-to-month terminations, landlords must provide at least 91 days written notice (C.R.S. § 13-40-107). Since April 2024, HB24-1098 (C.R.S. § 13-40-107.5) also requires landlords to have just cause before evicting any residential tenant.

Can my landlord lock me out or shut off utilities in Castle Pines?

No. Self-help evictions — including changing locks, removing doors, or shutting off utilities to force a tenant to leave — are prohibited under Colorado law. A landlord must obtain a court judgment before any eviction can be enforced. Tenants who are illegally locked out or have utilities shut off should contact law enforcement and consider filing a complaint or seeking emergency legal assistance.

What can I do if my landlord refuses to make repairs in Castle Pines?

Colorado's Warranty of Habitability Act (C.R.S. § 38-12-501) requires landlords to maintain rental units in a habitable condition. If your landlord fails to address a serious habitability issue after you provide written notice, you may be entitled to seek rent reduction, repair-and-deduct remedies, or lease termination. Document all repair requests in writing and consider contacting Colorado Legal Services if the landlord does not respond.
