- Must be returned within 30 days (or up to 60 days if the lease allows) with an itemized statement. Wrongful withholding entitles the tenant to treble damages plus attorney fees (C.R.S. § 38-12-103).
- Landlords must give month-to-month tenants at least 91 days written notice to terminate the tenancy (C.R.S. § 13-40-107).

1. Overview: Tenant Rights in Louisville
Louisville is a Boulder County city of roughly 22,000 residents situated between Boulder and Broomfield along the Front Range. As the city has grown, tenants increasingly ask about rent increases, security deposits, eviction protections, and what happens when a landlord refuses to make repairs.
Louisville has not enacted any local rent control, just-cause eviction, or renter-protection ordinances beyond what Colorado state law provides. That means the Colorado Warranty of Habitability Act, the statewide 91-day notice rule, the security deposit statute, and the 2024 for-cause eviction law (HB24-1098) are the primary sources of tenant protection for Louisville renters.
This article summarizes those protections as informational background only. It is not legal advice. Laws change and individual situations vary — consult a licensed Colorado attorney or a free legal aid organization if you have a specific question.
2. Does Louisville Have Rent Control?
Louisville, Colorado has no rent control or rent stabilization. Colorado state law (C.R.S. § 38-12-301) prohibited local rent control for decades. Senate Bill 21-173, enacted in 2021, lifted that statewide preemption and gave municipalities the authority to adopt rent control. However, Louisville has not passed any such ordinance, and no rent caps apply anywhere in Colorado as of May 2026.
Landlords in Louisville may raise rent by any amount with proper notice. For month-to-month tenancies, Colorado law requires at least 21 days written notice before a rent increase takes effect (C.R.S. § 13-40-107.5). Fixed-term leases can only be increased at renewal unless the lease expressly provides otherwise.
3. Colorado State Tenant Protections That Apply in Louisville
Colorado provides several important protections for Louisville tenants:
- Warranty of Habitability (C.R.S. § 38-12-501): Landlords must maintain rental units in a habitable condition, including adequate heat, running water, weatherproofing, and compliance with building codes. If a landlord fails to remedy a serious habitability problem after written notice, tenants may reduce rent proportionally or terminate the lease without penalty.
- Security Deposit Return (C.R.S. § 38-12-103): Landlords must return the deposit within 30 days of move-out (or up to 60 days if the lease permits) along with an itemized written statement of any deductions. Landlords who wrongfully withhold deposits face treble (triple) damages plus attorney fees.
- Notice to Terminate (C.R.S. § 13-40-107): A landlord must give a month-to-month tenant at least 91 days written notice before terminating the tenancy without cause.
- For-Cause Eviction (HB24-1098, effective April 2024): After a tenant has lived in a unit for 12 months, a landlord must have legal cause to evict or decline to renew the lease. Permissible causes include non-payment of rent, material lease violations, nuisance, demolition, substantial renovation, or owner move-in. Landlords must provide at least 90 days notice for no-fault evictions.
- Anti-Retaliation (C.R.S. § 38-12-509): Landlords may not retaliate against tenants who report code violations, complain to a government agency, or exercise any legal right. Retaliation may be raised as a defense in eviction proceedings.
- Self-Help Eviction Prohibited: Landlords cannot lock out tenants, remove doors or windows, or shut off utilities to force a tenant out. Such conduct is unlawful; tenants may seek immediate reinstatement and damages.
4. Security Deposit Rules in Louisville
Colorado law (C.R.S. § 38-12-103) does not cap the amount a landlord may charge as a security deposit, so Louisville landlords may set the deposit at any amount agreed in the lease.
Return deadline: The landlord must return the full deposit — or the balance after lawful deductions — within 30 days of the tenant vacating the unit. If the written lease authorizes a longer period, the deadline may extend to 60 days. The landlord must accompany any partial return with a written, itemized statement explaining each deduction.
Penalties for wrongful withholding: If a landlord willfully retains a deposit without a legitimate basis, the tenant is entitled to treble (triple) damages plus attorney fees and court costs. Colorado courts have interpreted this provision strictly — vague or blanket deductions can constitute wrongful withholding.
Practical steps: Document the unit's condition with photos at move-in and move-out, provide a forwarding address in writing, and retain a copy of your lease. These records are critical if you need to pursue a claim in small claims court.
5. Eviction Process and Your Rights in Louisville
Louisville landlords must follow Colorado's statutory eviction process. Self-help evictions — including lockouts, utility shutoffs, and removal of belongings — are illegal under Colorado law.
Notice Requirements
- Non-payment of rent: Landlord must provide a written Demand for Compliance or Possession giving the tenant at least 10 days to pay or vacate (C.R.S. § 13-40-104(1)(d)).
- Material lease violation: Written notice giving the tenant at least 10 days to cure the violation or vacate.
- Substantial lease violation or illegal activity: 3-day notice to quit, no opportunity to cure.
- Month-to-month termination (no fault): At least 91 days written notice to terminate (C.R.S. § 13-40-107).
- No-fault eviction under HB24-1098: At least 90 days notice required; valid grounds include demolition, substantial renovation, owner/family move-in, sale of the property, or the tenant's refusal to sign a renewal with reasonable terms.
Court Process
If the tenant does not comply with the notice, the landlord must file an Eviction (Unlawful Detainer) action in Boulder County Court. The tenant receives a court summons and has the right to appear and present a defense. A judge must issue a judgment before the landlord may remove the tenant; only a court-ordered writ of restitution, enforced by the sheriff, authorizes removal.
Just-Cause Protections (HB24-1098)
Since April 19, 2024, tenants who have resided in a Louisville rental unit for at least 12 consecutive months are protected against eviction or non-renewal without cause. A landlord who violates this requirement may face an unlawful-removal claim, and the tenant may assert the violation as an affirmative defense in any eviction proceeding.

Frequently Asked Questions
Does Louisville have rent control?
No. Louisville, Colorado has no rent control or rent stabilization ordinance. Colorado state law (C.R.S. § 38-12-301) historically banned local rent control, and while SB 21-173 (2021) lifted that statewide ban, Louisville has not passed any ordinance capping rents. Landlords may charge and raise rent at any amount with proper notice.
How much can my landlord raise my rent in Louisville?
There is no limit on rent increases in Louisville or anywhere else in Colorado. For month-to-month tenancies, the landlord must give at least 21 days written notice before a rent increase takes effect (C.R.S. § 13-40-107.5). For fixed-term leases, increases generally take effect at renewal unless the lease states otherwise.
How long does my landlord have to return my security deposit in Louisville?
Your landlord must return the deposit — with a written, itemized statement of any deductions — within 30 days after you move out, or up to 60 days if your lease permits the longer period (C.R.S. § 38-12-103). If your landlord wrongfully withholds any portion, you may sue for treble (triple) damages plus attorney fees.
What notice does my landlord need before evicting me in Louisville?
The required notice depends on the reason. Non-payment of rent requires a 10-day written demand; month-to-month terminations with no fault require at least 91 days notice (C.R.S. § 13-40-107); and no-fault evictions under Colorado's 2024 just-cause law (HB24-1098) require 90 days notice for tenants who have lived in the unit for 12 or more months. A court judgment is always required before the landlord can remove you.
Can my landlord lock me out or shut off utilities in Louisville?
No. Self-help evictions — including changing locks, removing doors or windows, and shutting off utilities — are illegal in Colorado regardless of whether rent is owed. If your landlord does any of these things, you can seek immediate reinstatement through the courts and may be entitled to damages. Contact Colorado Legal Services or Boulder Bridge to Justice for help.
What can I do if my landlord refuses to make repairs in Louisville?
Colorado's Warranty of Habitability Act (C.R.S. § 38-12-501) requires landlords to maintain rental units in a safe and habitable condition. If your landlord fails to address a serious habitability issue after written notice, you may be entitled to reduce your rent proportionally or terminate your lease without penalty. You can also report the problem to Louisville Code Enforcement or Boulder County. Keep all written communications and document conditions with photos.
