Acton is a suburban town in Middlesex County, Massachusetts, located approximately 25 miles northwest of Boston. While Acton is predominantly an owner-occupied community, a meaningful share of residents rent apartments, condominiums, and single-family homes. Renters here are governed entirely by Massachusetts state law, which provides some of the strongest baseline tenant protections in the country — particularly around security deposits, habitability, and landlord retaliation.
Acton has not enacted any local tenant-protection ordinances beyond what the Commonwealth requires. That means renters should focus on understanding their rights under the Massachusetts General Laws, including M.G.L. c. 186 (landlord-tenant relations), M.G.L. c. 111 (public health and the state Sanitary Code), and the regulations at 105 CMR 410. Whether your concern is a withheld security deposit, a landlord who won't fix a broken heater, or an unexpected eviction notice, state law defines your rights and remedies.
This page summarizes the tenant protections that apply to Acton renters as of April 2026. It is intended as an informational resource only and does not constitute legal advice. Laws can change, and individual circumstances vary — consult a licensed attorney or a legal aid organization if you face a specific housing problem.
Acton has no rent control, and Massachusetts state law currently prohibits no city or town from maintaining a rent control ordinance that was in effect before 1994. Massachusetts voters approved Question 9 in November 1994, a ballot initiative that repealed rent control across the entire state, including in cities like Boston, Cambridge, and Brookline that had well-established programs. The repeal took effect on January 1, 1995.
In 2020, the Massachusetts Legislature enacted Chapter 358 of the Acts of 2020, which removed the statewide preemption and theoretically allows municipalities to enact new rent stabilization ordinances through local action. However, as of April 2026, no Massachusetts city or town — including Acton — has enacted a new rent control or rent stabilization ordinance under this authority.
In practical terms, this means Acton landlords may increase rent by any amount at any time, provided they give proper advance notice. For month-to-month tenants, that notice must be at least 30 days and must expire at the end of a rental period (M.G.L. c. 186, § 12). For tenants with a fixed-term lease, the rent is locked in for the lease term, but the landlord may propose a higher rent upon renewal with no cap on the increase. Renters in Acton have no local authority to challenge the amount of a rent increase.
Even without local ordinances, Massachusetts law gives Acton tenants meaningful protections in several key areas:
Security Deposits (M.G.L. c. 186, § 15B): Landlords may not collect a security deposit exceeding one month's rent. The deposit must be held in a separate, interest-bearing bank account in Massachusetts, and the tenant must receive written notice of the bank name and account number within 30 days of paying the deposit. Landlords must also provide a receipt and, if the unit has pre-existing damage, a written statement of conditions within 10 days of the tenancy beginning. The deposit must be returned within 30 days of the tenancy ending, along with any accrued interest and an itemized list of any deductions.
Habitability and the State Sanitary Code (M.G.L. c. 111, § 127L; 105 CMR 410): Every residential rental unit in Acton must comply with the Massachusetts State Sanitary Code (105 CMR 410). Landlords are required to maintain heating (at least 68°F from September 16 to June 14), hot water, working plumbing and electrical systems, structural integrity, and freedom from pests. Tenants may report violations to the Acton Board of Health. If a landlord fails to cure a serious code violation, tenants may have the right to withhold rent, repair and deduct the cost of repairs (up to four months' rent), or terminate the lease under M.G.L. c. 111, § 127L.
Notice to Terminate (M.G.L. c. 186, § 12): A landlord must give a month-to-month tenant at least 30 days' written notice before terminating the tenancy, and the notice period must be timed to expire at the end of a full rental period. Tenants must give landlords the same 30-day notice before vacating. For tenants with a fixed-term lease, the tenancy ends on the lease expiration date unless renewed.
Anti-Retaliation Protection (M.G.L. c. 186, § 18): Massachusetts law prohibits landlords from retaliating against tenants who report housing code violations, contact the board of health, organize with other tenants, or exercise any other legal right. Any rent increase, reduction in services, or eviction action taken within six months of a protected activity is legally presumed to be retaliatory. A tenant who proves retaliation may recover up to three months' rent, attorney's fees, and costs.
Lockout and Utility Shutoff Prohibition (M.G.L. c. 186, § 14): A landlord may not remove a tenant from a rental unit by force, change the locks, remove doors or windows, or shut off utilities in order to pressure a tenant to leave. These "self-help" eviction tactics are illegal. A tenant subjected to such conduct may recover actual damages or three months' rent (whichever is greater), plus attorney's fees.
Anti-Discrimination (M.G.L. c. 151B): Massachusetts law prohibits housing discrimination based on race, color, national origin, religion, sex, disability, familial status, sexual orientation, gender identity, age, ancestry, marital status, military status, and source of income (including housing vouchers). Complaints may be filed with the Massachusetts Commission Against Discrimination (MCAD).
Massachusetts has among the strictest security deposit laws in the United States, and those rules apply fully to all Acton landlords under M.G.L. c. 186, § 15B.
Cap on Amount: A landlord may not collect a security deposit of more than one month's rent. This applies regardless of the rental price or the length of the lease. First and last month's rent are permitted in addition to the security deposit, but the deposit itself cannot exceed one month's rent.
Separate Account Requirement: The deposit must be deposited in a separate, interest-bearing account at a Massachusetts bank within 30 days of receipt. The landlord must give the tenant written notice of the institution's name and address and the account number. Interest accrues at the rate paid by the bank and must be paid to the tenant annually (or credited toward rent) and at the end of the tenancy.
Condition Statement: Within 10 days of the start of the tenancy, the landlord must provide the tenant with a written statement of the condition of the premises, noting any existing damage. The tenant has 15 days to return an amended statement. Failure to provide this statement may limit the landlord's ability to make deductions.
Return Deadline: The landlord must return the deposit within 30 days after the tenancy ends (or within 30 days after the tenant provides a forwarding address, whichever is later). The landlord must include a written, itemized list of any deductions with supporting documentation (such as receipts for repairs).
Penalties for Non-Compliance: If a landlord wrongfully withholds all or part of the security deposit — or fails to follow the procedural rules — the tenant may recover treble damages (three times the amount wrongfully withheld), plus interest, court costs, and attorney's fees under M.G.L. c. 186, § 15B(7). Courts have enforced treble damages even for technical violations of the deposit rules, making compliance critical for Acton landlords.
In Acton, evictions are governed by Massachusetts state law — specifically M.G.L. c. 186 and the summary process procedures in M.G.L. c. 239. Acton has no local just-cause eviction ordinance, so landlords are not required to cite a reason for terminating a tenancy beyond the required notice period (except that the termination cannot be retaliatory under M.G.L. c. 186, § 18).
Step 1 — Notice to Quit: Before filing any court action, a landlord must serve the tenant with a written Notice to Quit. The required notice period depends on the reason for eviction:
Step 2 — Summary Process Complaint: If the tenant does not vacate by the end of the notice period, the landlord may file a Summary Process (eviction) complaint in the appropriate court — typically the Middlesex County Housing Court or District Court. The tenant receives a summons and a scheduled hearing date.
Step 3 — Court Hearing: Both landlord and tenant appear before a judge. Tenants may raise defenses, including payment of rent, habitability problems (rent escrow), retaliation, discrimination, or improper notice. Tenants facing eviction are strongly encouraged to seek legal representation.
Step 4 — Judgment and Execution: If the court rules in the landlord's favor, the tenant typically has 10 days to appeal before a writ of execution (the order authorizing removal) is issued. Only a sheriff or constable may carry out the physical removal — a landlord has no authority to remove a tenant or their belongings without a court-issued writ of execution.
Self-Help Eviction Is Illegal: Under M.G.L. c. 186, § 14, a landlord who changes the locks, removes doors or windows, shuts off utilities, or physically removes a tenant without a court order commits an illegal self-help eviction. Tenants may sue for actual damages or three months' rent (whichever is greater), plus attorney's fees and costs.
