Colorado Roommate Agreement
A Colorado room rental agreement, commonly referred to as a roommate agreement, is a legally binding contract that outlines the terms and conditions for individuals sharing a living space. This document serves to clarify the responsibilities and expectations of each roommate, ensuring that all parties are aware of their obligations and rights.

Types of Colorado Roommate Agreement
Co-Tenancy
In a co-tenancy arrangement, all roommates are signatories on the same lease and share equal responsibilities to the landlord. This means that if one co-tenant fails to comply with the lease terms, the other co-tenants are also held liable. Co-tenants do not have the authority to evict one another; any issues must be addressed with the landlord.
Subtenancy
Subtenancy occurs when the original tenant acts as the landlord to a subtenant, collecting rent and managing rental issues. In this scenario, the original tenant has the right to evict the subtenant for misconduct, and the landlord can also take action against the subtenant if necessary. It is important to note that subleasing typically requires the landlord’s permission.
At-Will Tenancy / Guest Tenancy
An at-will tenancy or guest tenancy is an informal arrangement that may exist with or without the landlord’s consent. Colorado law discourages such arrangements, as a roommate who resides in a property for more than a couple of weeks without being on the lease may be classified as a subtenant, thereby acquiring full tenant rights and responsibilities.
Quick Guide to Writing a Colorado Room Rental Agreement
- Identify the Parties: Clearly state the names of all parties involved, the property address, and the landlord’s information, including contact details for all signatories.
- Lease Term: Specify the duration of the existing lease and the length of the roommate agreement.
- Security Deposit: Discuss how the security deposit will be divided among roommates and outline the rules for its return or any deductions.
- Rent Amount: Clearly state the total rent and how it will be divided among the roommates.
- Utility Payments: Outline how utility payments will be divided and designate who is responsible for making payments to the utility companies.
- Violation Rules: Establish rules regarding violations of the lease or roommate agreement and procedures for handling early move-outs.
- House Rules: List any house rules related to food sharing, cleaning responsibilities, guests, and other communal living aspects.
- Bedroom Assignments: Assign bedrooms and clarify which areas will be shared and which will remain private.
- Signatures: Ensure that all parties sign and date the agreement, and attach the landlord consent form.
Lease Violations in Roommate Situations
Roommates, as co-tenants, are “jointly and severally liable” for adhering to the terms of the original lease. This means that any co-tenant can be held accountable for violations. For example, if one roommate fails to pay their share of the rent, the landlord has the right to seek full payment from any of the co-tenants. If a roommate has not signed the original lease and the landlord has not consented to the roommate agreement, the original tenant remains liable for any violations committed by the roommate.
Resolving Roommate Disputes in Colorado
In the event of a dispute, the original lease takes precedence over the roommate agreement. Generally, house rules regarding food sharing, chores, and quiet hours are not enforceable in a court of law. Co-tenants experiencing disagreements unrelated to the lease may consider mediation or arbitration as a means of resolution.
Rental Application
A rental application may be utilized to verify a potential roommate’s credibility and income, providing an additional layer of assurance for all parties involved.
