Writing a Notice to Vacate in Colorado: Tenant Guide

A Colorado notice to vacate needs five things to be valid and useful: the date, your name and the property address, your planned move-out date, your signature, and delivery in a way your lease or Colorado law recognizes. Get those right and the rest of the move-out process goes smoothly.

How Much Notice Colorado Law Requires

Your lease controls first. If it sets a specific notice period, that is the number to use. When a lease is silent, Colorado's default under C.R.S. 13-40-107 runs in both directions for a tenancy at will: for a tenancy of a year or longer, the default is 91 days' written notice. For shorter tenancies, a shorter statutory minimum applies; check your lease or ask your landlord in writing to confirm the exact number of days before you set a move-out date.

Colorado's 2024 for-cause eviction law changed how landlords can end a tenancy without a qualifying reason, but it does not change your own obligation as a tenant to give proper notice when you choose to leave.

Do You Still Owe Rent After Giving Notice?

Yes. You are responsible for rent through the end of your notice period, even after you have told your landlord you are leaving. Giving 30, 60 or 91 days' notice (whatever your lease or Colorado's default requires) is not the same as ending your lease immediately; it starts a countdown during which you keep paying and your landlord starts marketing the unit to a new tenant.

What Your Notice to Vacate Should Include

• The date the notice is written
• Your name and the rental property's full address
• Your planned move-out date, calculated from your lease or Colorado's default notice period
• A reason for leaving, if you choose to include one (not required)
• Your signature

Check the Lease Before You Write Anything

Your lease is the roadmap for how the tenancy ends. It sets the required notice period, cleaning standards, and how to return keys. Following those terms exactly avoids confusion and protects you from a dispute over your final rent or deposit.

Keep the Tone Clear and Professional

Even if your reasons for leaving are frustrating, keep the notice itself factual and businesslike. This document becomes part of your rental record and can affect the reference your landlord gives your next property manager.

Delivery Method

Follow your lease's stated delivery method or Colorado law if the lease is silent. Certified mail is the most common choice because it creates a delivery record and gives you a copy for your own files. Some Colorado leases now allow email or a tenant portal for notice; check your lease before assuming email alone is sufficient.

Getting Your Security Deposit Back

Colorado law requires your landlord to return your deposit, minus an itemized list of deductions, within one month of move-out, unless the lease sets a longer period of up to 60 days. Document the unit's condition with photos and video on your way out, and request a written, itemized list if any deductions are taken. Colorado's warranty of habitability also means any pre-existing habitability issues you reported during the tenancy should already be on record, which helps if a deduction is disputed.

What If Your Landlord Disputes Your Move-Out Date

Keep your own copy of the notice, the delivery confirmation, and any written reply from your landlord. If your landlord claims they never received the notice or disputes the date you gave, that paper trail is what settles the disagreement. A certified mail receipt or a timestamped email is far more useful in that moment than a verbal conversation neither side can prove. If a dispute escalates beyond what a direct conversation can resolve, Colorado's county courts handle landlord-tenant disagreements, and many counties also offer free or low-cost mediation before a case reaches that point.

How Far Ahead to Start the Process

Start the notice-to-vacate process as soon as you know you are moving, not on the day your notice period technically begins. Reread your lease first, confirm the required notice period in writing with your landlord if anything is unclear, and calendar your move-out date immediately so you are not scrambling to finalize logistics while the clock on your notice period is already running.

Common Reasons Colorado Tenants Give Notice

• Rent increase: a renewal offer that exceeds what fits the budget, or a better rate found elsewhere
• Job relocation: a new position or a commute that no longer makes sense from the current unit
• Changing needs: more space, a different neighborhood, or proximity to parks, trails or a shorter commute
