Longmont is a city in Boulder County on the northern Front Range of Colorado. Renter protections in Longmont come entirely from Colorado state law — the city has not enacted local rent control or additional tenant ordinances. Colorado's Warranty of Habitability Act and security deposit statutes provide renters with meaningful rights, and the state's 91-day termination notice requirement is among the most tenant-protective in the country.
Longmont has no rent control, and Colorado state law prohibits municipalities from enacting rent caps. Landlords may raise rent by any amount, but for month-to-month tenancies they must provide at least 91 days' written notice before a new rent amount takes effect or before terminating the tenancy (C.R.S. § 13-40-107). This lengthy notice period gives tenants meaningful time to plan for changes.
All Longmont renters are protected by the following Colorado state law provisions:
Under C.R.S. § 38-12-103, your Longmont landlord must return your security deposit within 30 days of move-out (or within 60 days if your written lease specifically allows the longer period), along with a written itemized statement of any deductions. If your landlord wrongfully withholds any portion of your deposit, you may sue for three times the withheld amount plus attorney's fees. Document your unit at move-in and move-out with dated photos and a written checklist to protect your deposit.
Longmont landlords must follow Colorado's formal eviction process: provide proper written notice (typically 10 days for nonpayment of rent), wait for the notice period to expire, and file an eviction suit in Boulder County Court if the tenant does not comply. For ending a month-to-month tenancy without cause, at least 91 days' written notice is required (C.R.S. § 13-40-107). Tenants have the right to appear and contest the eviction in court. Lockouts, utility shutoffs, and removal of belongings without a court order are illegal in Colorado.
