Massachusetts Roommate Agreement
A Massachusetts roommate agreement, also known as a room rental agreement, is a legally binding contract that allows tenants to share a dwelling with one or more co-tenants. This agreement establishes the rules and responsibilities for cohabitation and is signed by all parties involved.

Types of Roommate Arrangements in Massachusetts
Co-Tenancy: In a co-tenancy arrangement, all roommates must sign the original lease with the landlord, sharing equal responsibilities. If one roommate violates the lease rules, all co-tenants are liable for the consequences.
Subtenancy: In a subtenancy situation, the original tenant acts as the landlord to the subtenant. The original tenant is responsible for addressing the subtenant’s rental issues and has the authority to evict the subtenant for misconduct.
At-Will Tenancy / Guest Tenancy: This informal arrangement treats the roommate as a guest, often without the landlord’s consent. After a certain period, the guest may only be removed through formal eviction by the landlord.
Writing a Massachusetts Room Rental Agreement
When creating a roommate agreement, the following elements should be included:
- Parties and Property: Clearly specify who is making the agreement, the property address, and the landlord’s contact information.
- Lease Term: Note the duration of the existing lease and how long the roommate agreement will last.
- Security Deposit: Discuss how the security deposit will be divided among roommates and the rules for its return or deductions.
- Rent Payment: State the total rent amount and how it will be split between the roommates.
- Utilities: Determine how utility payments will be divided and who will be responsible for making those payments.
- Lease Violations: Set rules for handling violations of the lease or roommate agreement, including what happens if someone needs to move out early.
- House Rules: Include any agreed-upon rules regarding food, cleaning, guests, and other shared responsibilities.
- Room Assignments: Decide how bedrooms will be divided and which areas will be shared or designated as private.
- Signatures: Ensure that all parties sign and date the agreement, and attach a completed landlord consent form.
Lease Violations in Roommate Situations
Roommates are considered “jointly and severally liable” for the terms of the original lease. This means that:
- Each co-tenant is fully responsible for adhering to all lease terms.
- The landlord can pursue full recovery from any co-tenant for violations of the lease.
- If a roommate has not signed the original lease and the landlord has not consented to the roommate agreement, the original tenant is liable for any violations committed by the roommate.
Resolving Roommate Disputes in Massachusetts
In the event of a dispute, the original lease takes precedence over the roommate agreement. Important points to consider include:
- House rules regarding shared responsibilities, such as chores and quiet hours, are generally not enforceable in a court of law.
- Co-tenants may consider mediation or arbitration as a means to resolve disagreements that are not related to the lease.

FAQs
A Massachusetts roommate agreement is a contract among roommates that outlines the rules of cohabitation and establishes responsibilities. It is important because it helps prevent disputes by clearly defining expectations regarding rent, utilities, and house rules, ensuring all parties are on the same page.
In a co-tenancy agreement, all roommates are on the same lease and share equal responsibilities to the landlord. This means that if one roommate fails to meet lease obligations, the others can also be held liable, making it crucial for all roommates to adhere to the agreed terms.
A Massachusetts room rental agreement should include details such as the parties involved, property address, lease term, security deposit arrangements, rent distribution, utility payment responsibilities, house rules, and procedures for handling lease violations or early move-outs.
In a roommate situation, all co-tenants are ‘jointly and severally liable’ for lease violations, meaning the landlord can seek full recovery from any one of the roommates. If one roommate fails to pay rent, the landlord can demand the entire amount from the other roommates.
Co-tenancy involves all roommates signing the same lease and sharing equal responsibilities to the landlord, while subtenancy occurs when one original tenant rents out part of the property to another tenant, who then becomes a subtenant. Subtenancy typically requires the landlord’s permission and carries different legal implications.
Roommates can resolve disputes by referring to the lease, which takes priority over the roommate agreement. For disagreements not related to the lease, they may consider mediation or arbitration with a neutral third party, as house rules are generally not enforceable in court.
If a roommate needs to move out early, the roommate agreement should outline the procedures for handling this situation, including how to manage rent payments and the security deposit. It’s essential to discuss this with all parties involved to avoid misunderstandings.
In Massachusetts, if a guest stays for an extended period, they may be considered a subtenant, which can complicate the original tenant’s rights. Landlords can set limits on how long a guest can stay without being on the lease, and violating guest rules can lead to eviction.
