Southborough is a small town in Worcester County, Massachusetts, located along the I-495 corridor west of Boston. While the town's rental market is smaller than urban centers like Worcester or Boston, renters in Southborough are fully covered by Massachusetts state tenant law — one of the most protective frameworks for renters in the United States.
Tenants in Southborough most commonly seek information about security deposit rules, what notice their landlord must give before ending a tenancy, and their rights when a unit falls into disrepair. Massachusetts sets strict statutory standards on all of these issues, and violations by landlords can carry significant financial penalties.
This page provides a plain-language summary of the laws that apply to Southborough renters as of April 2026. It is intended for informational purposes only and does not constitute legal advice. Renters with specific legal questions should contact a licensed Massachusetts attorney or a qualified legal aid organization.
Southborough has no rent control, and there is no prospect of one under current conditions. Massachusetts voters passed a statewide ballot initiative — Question 9 — in November 1994, which prohibited rent control in every city and town in the Commonwealth. That ban effectively ended the rent control programs that had existed in Boston, Cambridge, and Brookline.
In 2020, the Massachusetts Legislature passed Chapter 358 of the Acts of 2020, which repealed the 1994 ban and theoretically allows municipalities to enact their own rent stabilization ordinances again. However, as of April 2026, no Massachusetts city or town — including Southborough — has enacted a new rent control or rent stabilization ordinance.
In practice, this means Southborough landlords can raise rents by any amount between lease terms, provided they give the legally required notice. There is no cap on rent increases and no requirement that a landlord justify the amount of an increase. Tenants on a fixed-term lease are protected from mid-lease increases by the terms of their lease contract, but upon renewal or transition to month-to-month status, any rent increase agreed to in a new notice takes effect without restriction.
Massachusetts state law provides Southborough renters with several strong protections that apply regardless of the absence of local ordinances.
Implied Warranty of Habitability (M.G.L. c. 186, § 14; 105 CMR 410): Every residential landlord in Massachusetts is required by law to maintain rental units in a habitable condition. The Massachusetts Sanitary Code (105 CMR 410) establishes minimum standards covering heat, hot water, structural safety, pest control, and more. Landlords must provide heat at a minimum of 68°F between 7:00 a.m. and 11:00 p.m. and 64°F at all other times from September 15 through June 15. Tenants who discover code violations may report them to the Southborough Board of Health, which can inspect and order repairs.
Repair-and-Deduct and Rent Withholding (M.G.L. c. 111, § 127L): If a landlord fails to correct a condition that endangers health or safety after proper notice, Massachusetts tenants have the right to withhold rent, to repair the condition and deduct the cost from rent, or to pursue damages in court. These remedies require that the tenant follow the procedural steps set out in the statute.
Security Deposit Rules (M.G.L. c. 186, § 15B): Massachusetts imposes strict rules on security deposits — see the Security Deposit section below for full details.
Notice to Terminate (M.G.L. c. 186, § 12): For a month-to-month tenancy, either the landlord or the tenant must give at least 30 days' written notice before terminating, and the notice must expire at the end of a rental period (e.g., on the last day of the month for a monthly tenancy).
Anti-Retaliation Protection (M.G.L. c. 186, § 18): Landlords are prohibited from raising rent, reducing services, or initiating an eviction in retaliation for a tenant exercising a legal right — such as reporting a housing code violation, organizing with other tenants, or contacting a government agency. If a landlord takes an adverse action within six months of a protected act by the tenant, the retaliation is legally presumed, shifting the burden of proof to the landlord. Tenants who prevail on a retaliation claim may recover up to three months' rent, attorney's fees, and other damages.
Prohibition on Lockouts and Utility Shutoffs (M.G.L. c. 186, § 14): A landlord may not take self-help measures to force a tenant out. Changing locks, removing doors or windows, or deliberately interfering with utility service are all illegal under Massachusetts law. A landlord who engages in such conduct may be liable for actual damages, a penalty of three months' rent, and attorney's fees.
Anti-Discrimination (M.G.L. c. 151B): Massachusetts prohibits discrimination in housing on the basis of race, color, national origin, sex, sexual orientation, gender identity, disability, religion, familial status, age, marital status, military status, and receipt of public assistance (including Section 8 vouchers). The Massachusetts Commission Against Discrimination (MCAD) enforces these protections.
Massachusetts has some of the strictest security deposit regulations in the country, all governed by M.G.L. c. 186, § 15B. These rules apply fully to Southborough rentals.
Cap on Amount: A landlord in Southborough may not collect a security deposit greater than one month's rent at the time of collection. Collecting more than one month's rent as a security deposit is a violation of § 15B regardless of what the lease says.
Separate Interest-Bearing Account: The landlord must deposit the security deposit in a separate, interest-bearing bank account within the Commonwealth within 30 days of receiving it. The landlord must provide the tenant with a receipt stating the amount, the name of the bank, and the account number. The tenant is entitled to receive the interest earned each year (or have it credited toward rent), at the rate paid by the bank but no less than the rate set by the Comptroller of the Commonwealth under § 15B(3)(b).
Condition Statement: At or before the start of the tenancy, the landlord must provide a written statement of the condition of the premises (a move-in checklist). If the landlord fails to provide this, they lose the right to retain any portion of the security deposit for damages.
Return Deadline: The landlord must return the security deposit (plus accrued interest, less any lawful deductions) within 30 days after the tenancy ends. If the landlord withholds any portion, they must provide an itemized list of damages and their costs within that same 30-day window.
Penalties for Non-Compliance: If a landlord fails to comply with the return and itemization requirements — or improperly withholds the deposit — the tenant may sue for treble (triple) damages, meaning three times the amount wrongfully withheld, plus court costs and reasonable attorney's fees under M.G.L. c. 186, § 15B(7). This is one of the strongest deposit-return penalties in the nation.
Evictions in Southborough follow the Massachusetts summary process procedure governed primarily by M.G.L. c. 239 (the Summary Process statute) and related rules of the Housing Court and District Court.
Step 1 — Notice to Quit: Before filing in court, the landlord must serve a written Notice to Quit on the tenant. 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 with the appropriate court (Housing Court or District Court). For Southborough, cases are typically heard in the Worcester Housing Court. The tenant will receive a copy of the complaint and a court date.
Step 3 — Answer and Discovery: The tenant has the right to file a written Answer raising defenses and counterclaims (such as breach of the warranty of habitability or retaliation). Tenants should file their Answer by the deadline stated on the summons.
Step 4 — Hearing: Both parties appear before a judge. The tenant may present defenses, evidence of poor conditions, and any counterclaims. If the court finds in the landlord's favor, it will issue a judgment for possession.
Step 5 — Execution and Move-Out: If the landlord obtains a judgment, the court issues an Execution (writ of possession) no sooner than 10 days after judgment. A sheriff or constable — not the landlord — must carry out any physical removal. Tenants may request a stay of execution in cases of hardship.
No Just Cause Required: Massachusetts state law does not require Southborough landlords to have a specific reason (just cause) to terminate a market-rate tenancy at the end of a lease term or for a month-to-month tenant, provided proper notice is given. However, the eviction may not be retaliatory (M.G.L. c. 186, § 18).
Self-Help Eviction Is Illegal: A landlord may never remove a tenant by changing the locks, removing belongings, shutting off utilities, or using threats or physical force. Such conduct violates M.G.L. c. 186, § 14 and exposes the landlord to liability for actual damages, a penalty equal to three months' rent, and attorney's fees.
