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.
