What Happens If Your Roommate Moves Out in Colorado?

Sharing a rental can be cost-effective, but things get complicated when a roommate leaves unexpectedly. If you're renting in Colorado, it's important to understand your responsibilities and options if a roommate moves out before the lease ends. This guide explains your liability for rent, steps you should take, and the official support available in Colorado.

Understanding Lease Agreements and Rent Liability in Colorado

Whether you’re on a formal lease with your roommate or have an informal arrangement, your liability for rent depends on your agreement and Colorado law.

Joint vs. Individual Leases

• Joint Lease: Both (or all) roommates are named on a single lease. You are typically "jointly and severally liable," meaning each tenant is responsible for the full rent if one or more do not pay.
• Individual Lease: Each roommate signs a separate agreement with the landlord. If your roommate leaves, you are usually only responsible for your share.

If you don't know your lease type, check your lease agreement or contact your landlord for clarification.

When a Roommate Leaves: What Happens Next?

In most cases, if your roommate’s name is on the lease and they leave, you may still be legally responsible for the full rent. Here’s how Colorado law approaches this situation:

• If you and your roommate are on a joint lease, the landlord can require you to pay the full rent if your roommate defaults.
• If you have a subtenant (someone subletting from you), you may be responsible for their unpaid rent if they move out.
• Always notify your landlord in writing if a roommate moves out unexpectedly.

Subletting and Replacement Roommates

Colorado does not have a specific statewide subletting law, but most leases require landlord approval before bringing in a replacement roommate or subletting. Check your lease for a subletting or assignment clause.

• Many landlords use the Colorado Department of Local Affairs forms for lease assignments or sublets.
• Get written approval before a new roommate moves in to avoid future liability issues.

Key Official Forms for Renters in Shared Housing

• Notice of Intention to Vacate (no official state number): Use this to notify your landlord and co-tenants in writing if you or your roommate plan to move out. Always provide as much notice as your lease requires, usually 30 days. Download a sample template from the Colorado Department of Local Affairs Tenant Resources.
• Lease Assignment Agreement (no official state number): Use this if you want to legally transfer your lease obligation to a new roommate. Both the landlord’s and incoming tenant’s signatures are required. See sample agreements and guidance at the Colorado Department of Local Affairs.

Always keep copies of correspondence and forms for your records.

Tip: If you’re unsure how to proceed, Colorado’s Division of Housing offers free resources and guides for renters dealing with roommate or subletting situations.

Your Rights Under Colorado Tenancy Law

In Colorado, most landlord-tenant matters, including rent liability and shared housing, are governed by the Colorado Revised Statutes (C.R.S.) – specifically, Title 38, Article 12: Landlord and Tenant^[1].

• You cannot be evicted without written notice and a proper court process.
• The landlord or property manager cannot raise rent or change terms mid-lease unless all parties agree in writing.
• You have the right to request written clarification of your lease status if a roommate leaves.

If you face financial hardship due to a roommate moving out, communicate with your landlord right away and document all communication.

How to Take Action if a Roommate Leaves

• Review your lease for joint liability clauses.
• Contact your landlord immediately.
• Send written notice of your roommate’s departure.
• Discuss options for subletting or lease assignment when allowed.

FAQ: Roommate and Rent Liability in Colorado

1. Can my landlord evict me if my roommate leaves and I can't pay their share?
   Yes, under Colorado law, if you're jointly liable and rent is unpaid, your landlord can begin eviction proceedings. Always communicate with your landlord early to prevent this.
2. Can I legally replace my roommate without landlord approval?
   No, you usually need the landlord's written approval for a new roommate or sublet. Check your lease and always get permissions in writing.
3. If my roommate isn't on the lease, are they still responsible for rent?
   Likely not. Only those named on the lease are liable to the landlord, though you might pursue private legal action for unpaid shares.

   Visit the Colorado Department of Local Affairs Tenant Guide for up-to-date, official information.
