Marlborough is a mid-sized city in Middlesex County, Massachusetts, with a growing renter population drawn by its proximity to major employment corridors along Route 9 and I-495. As in all Massachusetts cities, Marlborough renters are governed by statewide tenant protections that are among the most comprehensive in the United States — covering security deposits, habitability, anti-retaliation, and eviction procedures.
Marlborough has not enacted any local tenant protection ordinances beyond what state law requires. That means renters here rely entirely on Massachusetts General Laws for their core protections. The most commonly searched topics for Marlborough renters include security deposit rules, how much notice a landlord must give before eviction, and what to do when a landlord refuses to make repairs.

Marlborough has no rent control, and landlords may raise rent by any amount with proper notice. Massachusetts voters passed a statewide ballot initiative — Question 9 — in November 1994 that eliminated rent control in every Massachusetts city, including Boston, Cambridge, and Brookline, which had active programs at the time. That 1994 repeal effectively prohibited any Massachusetts municipality from maintaining or enacting rent control.
In 2020, the state legislature passed Chapter 358 of the Acts of 2020, which removed the statewide statutory prohibition and gave cities and towns the legal authority to enact their own rent stabilization ordinances again. However, as of April 2026, no Massachusetts municipality — including Marlborough — has enacted a new rent control or rent stabilization ordinance. Marlborough's City Council has not introduced or passed any such measure.
In practical terms, this means your landlord in Marlborough can raise your rent to any amount they choose, provided they give you the legally required advance written notice before the increase takes effect. There is no cap, no formula, and no board to appeal to. Renters on fixed-term leases are protected from increases until the lease expires; month-to-month tenants are entitled to at least 30 days' written notice before a rent increase (M.G.L. c. 186, § 12).
Although Marlborough has no local ordinances, Massachusetts state law provides renters with substantial protections across several key areas.
Security Deposit Rules (M.G.L. c. 186, § 15B): Massachusetts imposes one of the strictest security deposit regimes in the country. A landlord may not collect more than one month's rent as a security deposit. The deposit must be held in a separate, interest-bearing bank account, and the landlord must provide the tenant with written notice of the bank's name, address, and account number within 30 days of receiving the deposit. The tenant earns interest on the deposit at the rate set by the Rental Deposit Act. The deposit must be returned — with an itemized statement of deductions — within 30 days after the tenancy ends.
Habitability and the Sanitary Code (M.G.L. c. 111, § 127L; 105 CMR 410): Every landlord in Massachusetts must maintain rental units in compliance with the State Sanitary Code (105 CMR 410), which sets minimum standards for heat, hot water, structural integrity, pest control, smoke and carbon monoxide detectors, and more. Landlords must provide heat to at least 68°F between 7:00 a.m. and 11:00 p.m. and 64°F at all other hours from September 15 through June 15. If a landlord fails to maintain these standards, tenants may report violations to the Marlborough Board of Health, withhold rent, pursue a repair-and-deduct remedy, or terminate the lease under M.G.L. c. 111, § 127L.
Notice Requirements (M.G.L. c. 186, § 12): A landlord must provide at least 30 days' written notice to terminate a month-to-month tenancy, and that notice must expire on the last day of a rental period. For example, if rent is due on the first of the month, a notice delivered on March 10 would not be effective until April 30. Tenants on fixed-term leases are protected through the lease end date.
Anti-Retaliation Protection (M.G.L. c. 186, § 18): Massachusetts law provides strong protection against landlord retaliation. A landlord may not raise rent, reduce services, bring or threaten eviction, or otherwise penalize a tenant for reporting code violations, contacting the Board of Health, organizing with other tenants, or exercising any other legal right. Critically, any adverse action taken within six months of a protected act is legally presumed to be retaliatory — the burden shifts to the landlord to prove otherwise. Tenants who prevail on a retaliation claim may recover up to three months' rent, plus attorney's fees and costs.
Lockout and Utility Shutoff Prohibition (M.G.L. c. 186, § 14): Self-help eviction is illegal in Massachusetts. A landlord who locks out a tenant, removes doors or windows, shuts off utilities, or otherwise attempts to force a tenant out without going through the court process is liable for the greater of actual damages or three months' rent, plus attorney's fees. This prohibition applies even if the tenant owes back rent.
Massachusetts has some of the most tenant-protective security deposit rules in the United States, and they apply in full to all Marlborough rentals under M.G.L. c. 186, § 15B.
Maximum deposit: No more than one month's rent. A landlord cannot collect a larger deposit regardless of the length of the lease or the tenant's credit history. If a landlord collects more than one month's rent as a deposit, the excess must be returned to the tenant.
Holding requirements: The security deposit must be held in a separate, interest-bearing escrow account at a Massachusetts bank. Within 30 days of receiving the deposit, the landlord must give the tenant written notice of the bank name, address, and account number. The landlord must also provide the tenant with a receipt and a separate list of any pre-existing damage to the unit (a condition statement) within 10 days of the tenancy beginning. Tenants should sign and date this statement; if you disagree with items listed, note your objections in writing.
Return deadline: The landlord must return the deposit — plus any accrued interest — within 30 days after the tenancy ends. If any deductions are made, the landlord must provide a written, itemized statement explaining each deduction along with receipts or invoices.
Penalties for non-compliance: The consequences for landlords who violate § 15B are severe. A tenant whose deposit is wrongfully withheld — or whose deposit was not held in compliance with the statute — may sue for treble damages (three times the deposit amount), plus court costs and reasonable attorney's fees. Courts have held that even technical violations of the holding or notice requirements can expose landlords to treble damages, making compliance critical for landlords and compliance-checking essential for tenants.
Eviction in Marlborough follows the Massachusetts summary process procedure governed by M.G.L. c. 239 and related statutes. A landlord must follow every step of the legal process; self-help eviction is strictly prohibited.
Step 1 — Notice to Quit: Before filing in court, the landlord must serve the tenant with a written Notice to Quit. The required notice period depends on the reason for eviction:
Step 2 — Summons and Complaint: If the tenant does not vacate after the notice period expires, the landlord may file a Summary Process Summons and Complaint in the Marlborough District Court (Eastern Middlesex Division). The landlord must pay a filing fee, and the tenant will receive a copy of the summons specifying the court date.
Step 3 — Answer and Hearing: The tenant has the right to file a written Answer raising defenses (such as retaliation, habitability violations, or improper notice) and counterclaims. Both parties appear at a hearing where a judge decides the outcome. Tenants who raise valid defenses can delay or defeat the eviction.
Step 4 — Judgment and Execution: If the landlord prevails, the court enters a judgment and — after a waiting period of at least 10 days — may issue an Execution, which is the legal document authorizing a constable or sheriff to remove the tenant. Only a constable or sheriff with a valid Execution may physically remove a tenant.
Just Cause Eviction: Massachusetts state law does not require just cause for most evictions. Marlborough has not enacted a just cause eviction ordinance. Landlords may terminate a month-to-month tenancy without stating a reason, provided they give proper notice — unless the termination is retaliatory (M.G.L. c. 186, § 18).
Self-Help Eviction is Illegal: Under M.G.L. c. 186, § 14, a landlord who locks out a tenant, removes belongings, shuts off heat, electricity, or water, or otherwise attempts to force out a tenant without a court order is liable for the greater of three months' rent or actual damages, plus attorney's fees and costs.
