A Massachusetts lease agreement is tightly regulated by state law, mainly M.G.L. c. 186, § 15B, which caps what a landlord can collect at signing, controls how security deposits are held and returned, requires specific written disclosures, and voids several common lease clauses. Getting the mechanics wrong is expensive: a landlord who mishandles a security deposit can owe the tenant three times the deposit plus interest, court costs, and attorney fees.
What a Landlord Can Charge at Move-In
Massachusetts allows only four payments at or before the start of a tenancy:
- First month’s rent.
- Last month’s rent, calculated at the same rate as the first month.
- A security deposit no larger than one month’s rent.
- The cost of purchasing and installing a new lock and key.
Nothing else is permitted.1General Court of Massachusetts. Massachusetts Code Chapter 186 – Section 15B Application fees, credit check fees, background check fees, move-in fees, pet fees, and holding deposits are all illegal. As of August 2025, brokers working on behalf of a landlord are also explicitly barred from charging prospective tenants application or credit check fees.2Mass.gov.

Required Disclosures
Lead Paint
For any property built before 1978, the landlord must notify tenants about lead paint hazards before the tenancy begins, using the state’s standardized brochure describing health risks, symptoms, and steps to reduce exposure. The tenant signs a transfer form confirming receipt.3General Court of Massachusetts. Massachusetts Code 111-197A – Lead Poisoning Prevention and Control
Statement of Condition
When a security deposit is collected, the landlord must give the tenant a written description of the unit’s existing condition within ten days after the tenancy starts or upon receiving the deposit, whichever is later.1General Court of Massachusetts. Massachusetts Code Chapter 186 – Section 15B The tenant then has fifteen days to add anything the landlord missed and return a corrected copy. A landlord who never provided the statement forfeits the right to keep any of the deposit for damages.
Real Estate Tax Pass-Through
If the lease requires the tenant to pay a share of real estate tax increases, the provision must state the tenant’s exact percentage of any increase and guarantee a proportionate refund if the landlord obtains an abatement. A clause that doesn’t meet these requirements is void.4General Court of Massachusetts. Massachusetts Code Chapter 186 – Section 15C
Owner Identification
The lease should state the name, address, and telephone number of the property owner or management company. Absentee landlords must make this information available to tenants.
Lease Clauses That Won’t Hold Up
Some lease language is automatically void, whether or not the tenant signed without objecting.
Any clause trying to shield a landlord from liability for injuries caused by their own negligence is unenforceable. That includes “hold harmless” wording covering hallways, stairways, elevators, and common areas.5General Court of Massachusetts. Massachusetts Code Chapter 186 Section 15
The landlord is responsible under the State Sanitary Code for keeping the premises safe, habitable, and up to health standards throughout the tenancy.6Mass.gov. The Attorney Generals Guide to Landlord and Tenant Rights A clause attempting to transfer structural maintenance or code-compliance duties to the tenant conflicts with that obligation and won’t survive in housing court.
“Self-help” eviction clauses are illegal. A landlord cannot change the locks, remove a tenant’s belongings, or shut off utilities to force someone out. Only a court order can compel a tenant to leave.7Mass.gov. Eviction for Tenants A lease that says otherwise has no legal effect, and a judge may strike the offending sections and award the tenant attorney fees.
Security Deposit Rules
Security deposits generate more Massachusetts landlord-tenant disputes than almost any other issue, largely because the rules are strict and the penalties are severe.
How the Deposit Must Be Held
The landlord must place the deposit in a separate, interest-bearing Massachusetts bank account, structured so the money stays protected in bankruptcy or foreclosure. Within thirty days of receiving the deposit, the landlord must give the tenant a receipt showing the bank’s name and location, the deposit amount, and the account number.1General Court of Massachusetts. Massachusetts Code Chapter 186 – Section 15B If that receipt never arrives, the tenant is entitled to an immediate return of the entire deposit.
Interest Payments
A landlord holding a deposit for a year or longer must pay interest at 5% per year or the actual bank rate, whichever is less. Interest is due at the end of each tenancy year, along with a written statement of the bank name, deposit amount, account number, and interest owed. If the tenant doesn’t get the notice or payment within thirty days after the tenancy anniversary, the interest can be deducted from the next rent payment.1General Court of Massachusetts. Massachusetts Code Chapter 186 – Section 15B The same rule applies to last month’s rent held in advance.
Returning the Deposit
After the tenancy ends, the landlord has thirty days to return the full deposit with accrued interest or provide a sworn, itemized list of deductions with written estimates or receipts for repairs. The itemized statement must be signed under the penalties of perjury. Normal wear and tear cannot be deducted, and any claimed damage must be documented.8Mass.gov. Massachusetts General Laws c.186 Section 15B
Triple Damages
If a landlord fails to deposit the money in a proper account, fails to return it within thirty days, or fails to provide a proper itemized deduction list, the tenant can sue for three times the deposit plus 5% interest from the date the money was due, court costs, and reasonable attorney fees.8Mass.gov. Massachusetts General Laws c.186 Section 15B Even a technically correct deduction made a day past the thirty-day deadline can trigger treble damages. Procedural failures are punished as harshly as bad-faith withholding.
Late Fees and Rent Increases
A lease cannot impose any penalty or interest for late rent until the payment is more than thirty days overdue.1General Court of Massachusetts. Massachusetts Code Chapter 186 – Section 15B A “rent due on the 1st, late fee on the 5th” clause is unenforceable. The lease must also specify the late fee for it to apply; if the lease is silent on the point, the landlord cannot add one after the fact.
During a fixed-term lease, rent cannot change unless the lease itself allows an increase at a specific time. On a month-to-month tenancy at will, the landlord must give written notice at least thirty days or one full month before the next rent due date, whichever is longer, before raising the rent.6Mass.gov. The Attorney Generals Guide to Landlord and Tenant Rights The notice has to state the new amount and the effective date. Massachusetts has no statewide rent control, so there is no cap on the size of an increase, though some municipalities have explored local measures.
When the Landlord Can Enter
A landlord may enter the unit to inspect it, make repairs, show it to prospective tenants or buyers, comply with a court order, or check for abandonment. In the final thirty days of a tenancy, entry is also allowed to assess potential security deposit deductions.1General Court of Massachusetts. Massachusetts Code Chapter 186 – Section 15B
Outside emergencies, the State Sanitary Code requires at least forty-eight hours’ written notice before entering for repairs. There is no statutory notice period for inspections or showings, but landlords who routinely enter without reasonable notice risk claims of interference with the tenant’s quiet enjoyment of the premises.
Ending the Lease Early
Breaking a fixed-term lease doesn’t automatically mean owing every remaining month’s rent. Massachusetts case law requires the landlord to make reasonable efforts to find a replacement tenant to minimize losses. If the unit re-rents quickly, the departing tenant’s exposure shrinks to the gap period plus reasonable re-letting costs.
Two situations allow a tenant to terminate early without penalty:
- Military deployment or relocation. The federal Servicemembers Civil Relief Act lets active-duty servicemembers with permanent change-of-station orders or deployment orders of ninety days or more terminate a residential lease. The servicemember delivers written notice and a copy of the orders to the landlord, and the lease ends thirty days after the next rent due date. No early termination fee applies.
- Domestic violence, sexual assault, or stalking. Under M.G.L. c. 186, § 24, a tenant who has experienced or reasonably fears domestic violence, rape, sexual assault, or stalking within the previous three months may terminate the lease early for safety reasons.
What the Lease Itself Should Cover
Beyond the mandated disclosures, a workable lease pins down the practical details that prevent later confusion: the full legal names of all adult occupants, the complete street address and unit number, the start and end dates, the monthly rent amount, the due date, and how rent is paid (check, electronic transfer, money order).
Utility responsibilities deserve their own section stating who pays for heat, hot water, gas, and electricity. If the tenant will be billed separately for water and sewer, the landlord must first install a submeter measuring only that unit’s water, and all fixtures must meet low-flow standards.9General Court of Massachusetts. Massachusetts Code Chapter 186 Section 22 A lease that assigns water costs without submetering in place is unenforceable on that point.
Rules about pets, smoking, parking, storage, and use of common areas should be spelled out clearly. Vague language like “no unreasonable noise” invites arguments; specific quiet hours or occupancy limits are easier to enforce. If the landlord intends to pass through real estate tax increases, the § 15C requirements described above have to be built into the clause.
Signing, Copies, and Receipts
Once both parties sign, the landlord has thirty days to deliver a fully executed copy of the lease to the tenant. Failure to do so is punishable by a fine of up to $300.10General Court of Massachusetts. Massachusetts Code Chapter 186 Section 15D A co-signer or guarantor should also receive a copy.
At signing, the landlord must provide separate, detailed receipts for every payment collected. The security deposit receipt must include the amount, the name of the person receiving it, the date, and a description of the premises. The last month’s rent receipt must state that the tenant is entitled to interest on the advance payment.1General Court of Massachusetts. Massachusetts Code Chapter 186 – Section 15B These receipts serve a separate record-keeping purpose from the lease and should not be combined into a single document. Organized copies of everything exchanged at this stage are what you’ll want on hand if a deposit dispute surfaces months or years later.
