Massachusetts, which established its legislative authority upon statehood on February 6, 1788, does not mandate a specific lease form, but the state's strict statutory protections mean leases must be carefully drafted to avoid containing illegal or unenforceable provisions.
Official Law Citation: Massachusetts General Laws Chapter 186, Section 15B(1)(b).
Written vs. Oral Leases
Both written and oral leases are legally valid in Massachusetts. Regardless of length, a written lease is universally recommended and essential for enforcement purposes.
Even without a formal written lease, a tenant has a "tenancy at will" and is still fully protected by applicable Massachusetts statutes, such as security deposit regulations (Ch. 186 § 15B).
Essential Lease Components
A compliant Massachusetts residential lease should include:
- Names of all parties and the property address.
- Amount of rent, due date, and acceptable payment methods.
- Lease term (start and end dates for a fixed term).
- Security deposit details (amount, bank information, statement of condition process).
- Utilities responsibilities.
- Maintenance and repair responsibilities.
- Rules regarding pets, guests, and subletting.
- Termination and renewal clauses.
Prohibited Lease Clauses
Massachusetts law voids certain clauses, regardless of whether the tenant signed the lease:
- Exculpatory clauses: Clauses attempting to indemnify the landlord or waive liability for negligence are void under M.G.L. c. 186, § 15.
- Excessive fees: Charging for normal wear and tear, non-refundable deposits, or "cleaning fees" beyond the permitted security deposit (Ch. 186 § 15B).
- Waiving rights to jury trial: In residential leases, clauses waiving the tenant's right to a jury trial are void under M.G.L. c. 186, § 15F.
Upfront Payment Limits
Under M.G.L. c. 186, § 15B(1)(b), a landlord may only collect the following payments at the start of a tenancy:
- First month's rent.
- Last month's rent (cannot exceed the first month's rent).
- Security deposit (cannot exceed one month's rent).
- The actual cost for the purchase and installation of a new lock and key.
Any other upfront charges, such as "application fees," "holding fees," or "pet deposits," are prohibited under the strict limits of Ch. 186 § 15B.
Frequently Asked Questions
▶What are the Massachusetts lease requirements for rental properties?
Massachusetts recognizes both written and oral leases, though written leases are strongly recommended for terms longer than one year. Lease agreements should include the rent amount, payment due date, security deposit terms, maintenance responsibilities, and rules regarding entry, pets, and subletting. Certain lease clauses that waive tenant statutory rights may be void and unenforceable under Massachusetts law.
▶What are the Massachusetts landlord-tenant laws every property owner should know?
Massachusetts has a reputation as one of the most tenant-protective states in the United States. Governed primarily by Massachusetts General Laws (MGL) Chapter 186 alongside the State Sanitary Code, the Commonwealth imposes strict regulations on security deposits, eviction procedures, habitability, and-as of 2025-real estate broker fees. This guide covers the essential compliance requirements for property owners and landlords.

The Massachusetts eviction process requires landlords to provide written notice to tenants before filing a court action. The type and length of notice depends on the reason for eviction — typically shorter for non-payment of rent and longer for lease violations or no-fault terminations. Self-help evictions (changing locks, removing belongings, shutting off utilities) are illegal in Massachusetts. The full court process varies but typically takes several weeks.

Massachusetts has specific rules governing how much landlords can charge for security deposits, how deposits must be held, and the deadline for returning deposits after a tenant moves out. Landlords must provide an itemized statement of any deductions made from the deposit. Failure to comply with deposit return deadlines can result in penalties and the forfeiture of the landlord's right to claim deductions.
Read the complete guide▶What are the Massachusetts rent increase laws and caps for landlords?
Massachusetts has specific rules governing when and how landlords can increase rent. During a fixed-term lease, rent generally cannot be increased unless the lease explicitly allows it.

Check whether Massachusetts has any local rent control ordinances that may impose additional caps or requirements.
Read the complete guide▶What is the grace period for late rent in Massachusetts?
Massachusetts has specific rules regarding grace periods for late rent and the amount that can be charged as a late fee.
