Groton is a small, predominantly residential town in Middlesex County, Massachusetts, located in the Nashoba Valley region northwest of Boston. While Groton's rental market is modest compared to urban centers like Boston or Lowell, renters here are fully protected by Massachusetts state tenant law — some of the strongest in the country. Tenants in Groton most commonly seek information about security deposit rules, landlord repair obligations, and the eviction process.
Massachusetts law sets strict standards for how landlords must handle security deposits, maintain rental units, and provide notice before ending a tenancy. These protections apply uniformly across the Commonwealth, meaning Groton renters enjoy the same baseline rights as tenants in much larger cities. Groton has not enacted any additional local tenant ordinances beyond what state law requires.

If you are facing an eviction, a security deposit dispute, or unsafe housing conditions, contact a licensed attorney or a local legal aid organization for guidance specific to your circumstances.
Groton has no rent control, and Massachusetts state law does not permit it at the local level under current practice. In November 1994, Massachusetts voters approved Question 9, a statewide ballot initiative that repealed all existing rent control ordinances — including those in Boston, Cambridge, and Brookline — and barred municipalities from enacting new ones. That prohibition remained in effect until 2020, when the state legislature passed Chapter 358 of the Acts of 2020, which technically lifted the statewide ban and allowed cities and towns to petition the legislature to enact local rent stabilization measures.
However, as of April 2026, no Massachusetts municipality — including Groton — has successfully enacted a new rent control ordinance. Groton has not pursued such legislation, and there are no local caps on how much a landlord can raise rent. Landlords in Groton are free to set rents at any amount and may increase rent upon proper notice at the end of a lease term or rental period. In practice, this means Groton renters have no statutory protection against rent increases of any size, provided the landlord follows proper notice procedures.
Massachusetts provides some of the most comprehensive tenant protections in the United States. The following state-level rights apply to all renters in Groton.
Security Deposit Rules (M.G.L. c. 186, § 15B): Landlords may collect a security deposit of no more than one month's rent. The deposit must be held in a separate, interest-bearing bank account, and the tenant must receive written notice of the bank name, address, and account number within 30 days. At the end of the tenancy, the landlord must return the deposit — plus accrued interest — within 30 days, along with an itemized written statement of any deductions. Failure to comply can result in the tenant recovering the full deposit amount plus treble (triple) damages, interest, and attorney's fees.
Habitability and Repairs (M.G.L. c. 111, § 127L; 105 CMR 410): Every landlord in Massachusetts is required to maintain rental units in compliance with the state Sanitary Code (105 CMR 410). This code sets minimum standards for heat (at least 68°F from September 16 through June 14), hot water, structural integrity, pest control, and more. Tenants who identify code violations may report them to the Groton Board of Health or the local housing authority. If conditions are serious and the landlord fails to act, tenants may have the right to withhold rent, make repairs and deduct the cost from rent, or terminate the lease — all subject to specific legal requirements.
Notice to Terminate Tenancy (M.G.L. c. 186, § 12): A landlord must provide at least 30 days' written notice to terminate a month-to-month tenancy. The notice must be timed to expire at the end of a rental period (e.g., the last day of the month). Tenants must also provide the same notice if they intend to vacate. For fixed-term leases, the lease itself defines when the tenancy ends, though landlords must still follow proper procedures if they do not intend to renew.
Anti-Retaliation Protection (M.G.L. c. 186, § 18): Landlords are prohibited from retaliating against tenants who exercise their legal rights, including reporting code violations, contacting a housing authority, or organizing with other tenants. If a landlord raises rent, reduces services, or begins eviction proceedings within six months of a tenant's protected activity, the law presumes the action is retaliatory. A tenant who prevails on a retaliation claim may recover one to three months' rent, plus attorney's fees and costs.
Lockout and Utility Shutoff Prohibition (M.G.L. c. 186, § 14): It is illegal in Massachusetts for a landlord to lock out a tenant, remove doors or windows, or shut off utilities — including heat, water, or electricity — in order to force a tenant to leave. These are known as self-help evictions and are specifically prohibited. A tenant subjected to such conduct may recover actual and consequential damages or three months' rent — whichever is greater — plus attorney's fees.
Discrimination Protections (M.G.L. c. 151B): Massachusetts law prohibits housing discrimination based on race, color, national origin, sex, religion, disability, familial status, ancestry, age, sexual orientation, marital status, military or veteran status, or receipt of public assistance (including Section 8 vouchers). The Massachusetts Commission Against Discrimination (MCAD) enforces these protections and accepts complaints from tenants who believe they have been discriminated against.
Massachusetts security deposit law — governed by M.G.L. c. 186, § 15B — is among the strictest in the nation, and it applies in full to Groton rentals.
Cap: A landlord in Groton may collect a security deposit of no more than the equivalent of one month's rent. There is no exception for furnished units or any other circumstance. Landlords may also collect first month's rent, last month's rent, and the cost of a new key or lock — but nothing beyond these amounts.
Holding Requirements: The security deposit must be deposited in a separate, interest-bearing account at a Massachusetts bank within 30 days of receipt. The landlord must provide the tenant with a written receipt stating the bank name, address, and account number. Annual interest accrues at the rate paid by the bank or 5% per year, whichever is less, and must be paid to the tenant each year or credited toward rent.
Condition Statement: Within 10 days of the tenancy's start date (or upon receipt of the deposit, if later), the landlord must provide the tenant with a written statement of the condition of the rental unit. The tenant has the right to note any disagreements with that statement within 15 days.
Return Deadline: After the tenancy ends, the landlord has exactly 30 days to return the security deposit (plus accrued interest), along with an itemized written statement detailing any deductions. Allowable deductions are limited to unpaid rent and damage beyond normal wear and tear, with receipts or written estimates required for each claimed repair.
Penalties for Non-Compliance: If a landlord fails to return the deposit on time, fails to provide required documentation, or makes improper deductions, the tenant may sue and recover the full deposit amount plus treble (triple) damages, interest, court costs, and reasonable attorney's fees. These penalties are among the most severe in any state, making strict compliance essential for landlords and an important protection for tenants.
Massachusetts has a structured eviction process that landlords must follow precisely. In Groton, all evictions are governed by state law — specifically M.G.L. c. 186 and M.G.L. c. 239 (the summary process statute). There is no local just cause eviction ordinance in Groton.
Step 1 — Notice to Quit: Before filing anything in court, a 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 to Quit expires, the landlord must file a Summary Process (eviction) action in the Eastern Middlesex Housing Court or the appropriate district court. The court will schedule a hearing and issue a Summons to the tenant.
Step 3 — Answer and Hearing: The tenant has the right to file a written Answer raising defenses — such as retaliation, poor conditions, or improper notice — and to appear at the hearing. Tenants who raise counterclaims (e.g., violations of the security deposit law or the anti-retaliation statute) may actually be entitled to damages from the landlord.
Step 4 — Judgment and Appeal: If the court rules in favor of the landlord, a judgment for possession is entered. The tenant has 10 days to appeal. If no appeal is filed, the landlord may request an execution — a court order allowing a constable to physically remove the tenant — after the 10-day period.
Step 5 — Physical Removal: Only a licensed constable or sheriff may carry out the physical removal of a tenant. The landlord has no authority to remove a tenant unilaterally.
Self-Help Eviction is Illegal (M.G.L. c. 186, § 14): A landlord may never lock out a tenant, remove belongings, change locks, or shut off utilities as a method of forcing a tenant to leave. These actions are illegal regardless of whether the tenant has paid rent or violated the lease. Tenants subjected to self-help eviction may recover actual damages or three months' rent — whichever is greater — plus attorney's fees.
No Just Cause Required in Groton: Unlike Boston, which enacted a Just Cause Eviction ordinance in 2024, Groton has no such requirement. A landlord may terminate a month-to-month tenancy without giving a reason, as long as proper notice is provided. At the end of a fixed-term lease, a landlord is generally not required to renew the tenancy.
