Lexington is a mid-sized town in Middlesex County, northwest of Boston, known for its high cost of living and competitive rental market. Renters in Lexington face some of the highest rents in the Greater Boston region, making a clear understanding of tenant rights especially important for those navigating lease renewals, deposit disputes, or potential evictions.
While Lexington has no local tenant protection ordinances beyond what Massachusetts state law provides, state law itself is among the strongest in the country in several key areas — particularly security deposits, habitability standards, and anti-retaliation protections. Most renters searching for help in Lexington want to know about rent increases, deposit returns, and what happens when a landlord tries to end a tenancy.
This page summarizes the laws that apply to renters in Lexington as of April 2026. It is intended as general information only and does not constitute legal advice. For guidance specific to your situation, consult a qualified attorney or one of the legal aid organizations listed below.
Lexington has no rent control ordinance. Massachusetts voters approved a statewide ballot initiative (Question 9) in November 1994 that repealed rent control in every Massachusetts city, including Cambridge, Boston, and Brookline, where it had previously existed. This referendum effectively eliminated rent stabilization across the entire state.
In 2020, the Massachusetts legislature passed Chapter 358 of the Acts of 2020, which removed the statewide prohibition on rent control and gave municipalities the legal authority to enact their own local rent stabilization ordinances if they chose to do so. However, as of April 2026, no Massachusetts city or town — including Lexington — has enacted a new rent control or rent stabilization ordinance. Lexington has also not introduced any such legislation locally.
What this means in practice: a landlord in Lexington may raise your rent by any amount, at any time, provided they give you legally required advance notice. For month-to-month tenants, that means at least 30 days' written notice before the increase takes effect (M.G.L. c. 186, § 12). For tenants with a fixed-term lease, the rent cannot be changed until the lease expires unless the lease itself allows for it. There is no cap on rent increases in Lexington.
Massachusetts state law provides several important protections for renters in Lexington. Each applies automatically — tenants do not need to take any action to be covered by them.
Security Deposits (M.G.L. c. 186, § 15B): Landlords may not collect a security deposit exceeding one month's rent. The deposit must be deposited in a separate, interest-bearing bank account within Massachusetts within 30 days of receipt. The landlord must provide the tenant with written notice of the bank name, branch, account number, and current interest rate. The deposit must be returned within 30 days after the tenancy ends, along with accrued interest and an itemized written statement of any deductions. Failure to comply can result in the tenant recovering up to three times the deposit amount, plus attorney's fees.
Habitability and the Sanitary Code (M.G.L. c. 111, § 127L; 105 CMR 410): Every residential rental unit in Massachusetts must meet the State Sanitary Code (105 CMR 410). Landlords are required to maintain heat (at least 68°F between 7 a.m. and 11 p.m. from September 15 to June 15), hot water, working plumbing, adequate weatherproofing, and freedom from pests and structural hazards. If a landlord fails to maintain these conditions, tenants may report violations to the Lexington Board of Health. Tenants may also have the right to withhold rent, make repairs and deduct the cost from rent, or terminate the lease under M.G.L. c. 111, § 127L, depending on the severity of the violations.
Notice to Terminate (M.G.L. c. 186, § 12): For month-to-month tenancies, either the landlord or tenant must give at least 30 days' written notice before the end of a rental period to terminate the tenancy. The notice period must align with the rental period — meaning a notice given on the 15th of the month cannot require vacation by the 15th of the following month if rent is due on the first. Fixed-term leases expire at their stated end date without additional notice, unless the parties agree otherwise.
Anti-Retaliation Protection (M.G.L. c. 186, § 18): Massachusetts law prohibits landlords from retaliating against tenants who exercise their legal rights — including reporting housing code violations, contacting a government agency, or organizing with other tenants. Any rent increase, reduction in services, or eviction action taken within six months of a protected act is presumed retaliatory by law. The burden then shifts to the landlord to prove a legitimate, non-retaliatory reason. Tenants who successfully prove retaliation may recover up to three months' rent, plus attorney's fees and costs.
Lockout and Utility Shutoff Prohibition (M.G.L. c. 186, § 14): A landlord may not remove a tenant from their home except through the formal court eviction process. Changing the locks, removing doors or windows, shutting off utilities, or physically removing a tenant's belongings is illegal self-help eviction. A tenant subjected to an unlawful lockout may sue for actual damages or three months' rent — whichever is greater — plus attorney's fees.
Massachusetts has some of the strictest security deposit rules in the United States, and all of them apply to renters in Lexington. The governing statute is M.G.L. c. 186, § 15B.
Cap on Amount: A landlord in Lexington may collect a security deposit of no more than one month's rent. Collecting more than this is a violation of state law, regardless of what a lease says.
Holding Requirements: Within 30 days of receiving a security deposit, the landlord must deposit it in a separate, interest-bearing account at a Massachusetts bank. The landlord must give the tenant written notice of the bank's name and address, the account number, and the current interest rate. Each year, the landlord must either pay the tenant the interest earned or credit it toward rent.
Condition Statement: At or before the start of the tenancy — and within 10 days of receiving the deposit — the landlord must provide the tenant with a written statement of the condition of the unit (a move-in checklist). The tenant has 15 days to object to the list in writing. Failure to provide this statement may eliminate the landlord's right to make deductions from the deposit.
Return Deadline: After the tenancy ends, the landlord has 30 days to return the deposit (plus interest), along with a written, itemized statement of any deductions for unpaid rent or damage beyond normal wear and tear. Deductions for normal wear and tear are not permitted.
Penalties for Violations: If a landlord fails to return the deposit on time, fails to provide the required itemized statement, or wrongfully withholds any portion of the deposit, the tenant may be entitled to recover up to three times the amount wrongfully withheld, plus interest, court costs, and reasonable attorney's fees (M.G.L. c. 186, § 15B(7)).
In Lexington, a landlord must follow the formal court eviction process — called a summary process action — to remove a tenant. There is no just cause eviction requirement under Massachusetts state law for most residential tenancies (unlike Boston, which enacted a Just Cause Eviction ordinance in 2024). This means a Lexington landlord may terminate a month-to-month tenancy without stating a reason, as long as proper notice is given.
Step 1 — Written Notice: Before filing in court, the landlord must serve the tenant with written notice. The type of notice depends on the reason for eviction:
Step 2 — Summons and Complaint: If the tenant does not vacate after the notice period, the landlord may file a Summary Process Summons and Complaint in the Middlesex County Housing Court (or District Court). The tenant will receive a summons stating the court date.
Step 3 — Answer and Hearing: The tenant has the right to file a written answer raising defenses or counterclaims — for example, that the eviction is retaliatory (M.G.L. c. 186, § 18), that the landlord failed to maintain the unit (M.G.L. c. 111, § 127L), or that the deposit rules were violated (M.G.L. c. 186, § 15B). A hearing is held before a judge.
Step 4 — Judgment and Execution: If the court rules in the landlord's favor, a judgment for possession is entered. The landlord must then obtain an Execution (a court order) before a constable can remove the tenant. A tenant has 10 days after judgment to appeal or request a stay of execution.
Self-Help Eviction is Illegal: A landlord in Lexington may never remove a tenant by changing the locks, removing doors, cutting off utilities, or removing the tenant's belongings. These acts are illegal under M.G.L. c. 186, § 14 and may entitle the tenant to damages equal to three months' rent or actual damages — whichever is greater — plus attorney's fees.
