1. Overview: Tenant Rights in Boulder
Boulder is the county seat of Boulder County and home to a large student and professional renter population. All residential rentals in Boulder are governed by Colorado statewide landlord-tenant law, including the Warranty of Habitability Act (C.R.S. § 38-12-501), the Security Deposit Act (C.R.S. § 38-12-103), and anti-retaliation protections under C.R.S. § 38-12-509. Colorado lifted its ban on local rent control in 2021 via SB 21-173, but Boulder has not enacted a rent control ordinance. Boulder does not have additional local tenant protection ordinances beyond state law.
2. Does Boulder Have Rent Control?
Colorado lifted its prohibition on local rent control ordinances in 2021 (SB 21-173, amending C.R.S. § 38-12-301), but as of April 2026 Boulder has not enacted rent control. Landlords in Boulder may raise rent by any amount at lease renewal or with proper notice on a month-to-month tenancy.
3. Colorado State Tenant Protections That Apply in Boulder
Colorado law provides these key protections for Boulder renters:
Security Deposit: Must be returned within 30 days of move-out (or up to 60 days if the lease allows) with a written itemized statement. Wrongful withholding entitles the tenant to treble damages plus attorney's fees (C.R.S. § 38-12-103).
Notice to Terminate: Month-to-month tenants must receive at least 21 days' written notice before the landlord can terminate the tenancy (C.R.S. § 13-40-107).

Lockout Prohibition: Self-help eviction is prohibited. Landlords must obtain a court judgment before removing a tenant.

Under C.R.S. § 38-12-103, your landlord must return your security deposit within 30 days of move-out (or up to 60 days if your lease specifically allows the longer period), along with a written itemized statement of deductions. If your landlord wrongfully withholds any portion, you may be entitled to treble damages (three times the withheld amount) plus attorney's fees. Document the unit's condition at move-in and move-out with photos and provide your forwarding address in writing.

To evict a tenant in Boulder, a landlord must serve written notice — typically 10 days for nonpayment of rent — then file a Forcible Entry and Detainer (FED) action in Boulder County Court if you do not vacate. You have the right to contest the eviction at a hearing. Self-help eviction is illegal in Colorado; landlords who change locks or shut off utilities may face civil liability and damages.
