Massachusetts Landlord-Tenant Laws 2026: What Renters and Landlords Need to Know

Massachusetts Rental Law in 2026: The Renter’s and Owner’s Guide

The domestic-violence lease citation that circulates for Massachusetts, “Ch. 186 Sec. 24-29,” names five sections that don’t exist for this purpose — the actual provision is a single section, § 24, and it doesn’t work the way a flat “30-day notice” implies. A tenant has a 3-month window from the most recent qualifying incident to invoke it, and once they do, they get up to 3 months to actually move out — there’s no fixed 30-day figure anywhere in the mechanic. A second correction, on repair-and-deduct: Massachusetts really does have one, M.G.L. c. 111 § 127L, but it needs a certified violation first (usually from the local Board of Health) and caps the deduction at 4 months’ rent in any 12-month span — a real, generous ceiling most guides never mention. Chapter 186 of the General Laws still anchors most of what’s below.

Security Deposits in Massachusetts

Requirement Massachusetts Law
Maximum Deposit 1 month’s rent — one of the tightest caps in the country
Last Month’s Rent Collectible separately from the deposit, up front, and treated under its own set of rules
Holding Requirement Separate interest-bearing account at a Massachusetts bank
Interest 5% per year, or the actual rate the account earns if that’s higher
Return Deadline 30 days after tenancy ends, with an itemized statement
Receipt Requirement Within 30 days: bank name, account number, and deposit amount in writing
Noncompliance Penalty Tenant can be entitled to the full deposit back plus treble damages if the landlord doesn’t follow the holding and receipt rules

Last month’s rent and the security deposit look similar at move-in but aren’t the same money under the law — mixing them up in a demand letter or a dispute weakens the claim rather than strengthening it.

Lease Agreements and Disclosures

A Massachusetts tenancy at will doesn’t need a written lease to be enforceable — M.G.L. c. 183 § 3 says an oral lease simply creates a tenancy at will rather than voiding the deal outright, and that section sets no year-based length threshold the way many other states’ statutes of frauds do. Disclosures a landlord owes before or at signing:

  • Massachusetts’s own lead-paint disclosure, which reaches further than the federal pre-1978 rule
  • A written statement of the unit’s condition at move-in
  • Insurance information
  • The name and address of the owner or an authorized managing agent

Rent Increases and Late Fees

Rule Massachusetts Law
Rent Control Abolished statewide by ballot question in 1994; no city or town can bring it back under current law
Notice for Increase, At-Will Rental-period length or 30 days, whichever is longer
Late Fee Timing Can’t be assessed until rent is a full 30 days past due — the longest mandatory wait of any state in this family, and it can’t be shortened by the lease
Late Fee Amount No statutory percentage cap once the 30 days run, but the fee still has to be reasonable

Eviction Process in Massachusetts

Eviction Type Notice/Cure Period Details
Non-Payment, Fixed-Term Lease 14-day notice to quit (M.G.L. c. 186 § 11) Tenant can still cure any time before the answer is due in court by paying all rent, interest, and costs — the cure window isn’t capped at 14 days the way the notice period is
Non-Payment, Tenancy at Will 14-day notice, with a 10-day cure right (c. 186 § 12) The 10-day cure-by-paying right only applies if the tenant hasn’t already used it on a nonpayment notice in the past 12 months — one bite, not a standing right. The notice itself must carry a specific disclosure of this right; leave it out, and the tenant’s cure window extends to the court answer date instead.
Lease Violation, Fixed-Term Whatever the lease itself specifies Chapter 186 doesn’t impose a separate statutory cure period for generic lease violations the way it does for nonpayment
No-Cause, At-Will Rental-period length or 30 days, whichever is longer An at-will landlord can end the tenancy for any lawful reason, or none, on this same notice — there’s no shorter “violation” track

Since April 2023, a residential nonpayment notice to quit has to come with the state’s official companion form (c. 186 § 31) — a notice missing it can be defective. Massachusetts courts don’t publish one verified number for how long a contested case runs start to finish; housing court dockets and how hard a case is fought both move that number more than any guide’s flat range does.

Maintenance and Repair Obligations

Implied Warranty of Habitability

The State Sanitary Code (105 CMR 410) sets the floor for heat, plumbing, structure, ventilation, pest control, and electrical systems, and no lease can waive it.

Repair-and-Deduct — With Its Real Cap and Its Own Gate

M.G.L. c. 111 § 127L isn’t a simple “notify and deduct” remedy. A tenant first needs the condition certified as a violation — by the local Board of Health in most cities and towns, but by the commissioner of housing inspection specifically in Boston, Worcester, and Cambridge. From there, the landlord gets 5 days to start the repair and 14 days to substantially finish it. Miss either deadline, and the tenant may arrange the repair and deduct the reasonable, actual cost from rent. The part almost no guide mentions: the deduction is capped at 4 months’ rent in any rolling 12-month period, calculated on the highest monthly rent charged during the tenancy or in the 12 months before the repair, whichever period is shorter. When a violation hits common areas or more than one unit, that 4-month figure is a shared ceiling across every affected tenant together, not 4 months apiece. The statute also gives a tenant an exit most guides skip: instead of repairing and deducting, they can treat the lease as abrogated, pay only fair value for their actual use of the unit, and vacate within a reasonable time. A landlord can’t retaliate by raising the rent to claw back a repair deduction made under this statute without a court order first. Separately, c. 239 § 8A gives tenants a rent-withholding defense in an eviction case itself, proportional to how much a habitability problem reduced the unit’s value — a different remedy from repair-and-deduct, raised in court rather than acted on unilaterally beforehand.

Tenant Rights and Protections

Protection Massachusetts Law
Entry Notice No statute sets a specific number of hours; the standard is reasonable notice at a reasonable time
Retaliation Protection Presumption of retaliation for actions taken within 6 months of a tenant exercising a legal right (M.G.L. c. 186 § 18)
Domestic Violence / Sexual Assault / Stalking M.G.L. c. 186 § 24 — not “§§ 24-29.” A tenant has 3 months from the most recent qualifying incident to give written notice, and up to 3 months after that to actually vacate. Acceptable proof is any one of: a valid c. 209A or c. 258E protective order, a police or court record naming the incident (and the perpetrator, if known), or written third-party verification from a qualifying program or professional.

Frequently Asked Questions

What’s the correct citation for Massachusetts’s domestic-violence lease law? M.G.L. c. 186 § 24 — a single section, not the “§§ 24-29” range some guides print. It also doesn’t run on a flat 30-day notice; the tenant has a 3-month window to invoke it and up to 3 months to move out once they do.

Is there a dollar limit on Massachusetts repair-and-deduct? Yes — 4 months’ rent in any rolling 12-month period, after Board of Health certification and the landlord’s 5-day/14-day window to act. Most guides that mention this remedy skip the cap entirely.

How much notice does a Massachusetts tenant get to cure unpaid rent? It depends on the tenancy. A fixed-term lease tenant can pay and cure any time up to the court answer date. An at-will tenant gets a specific 10-day cure right, but only once every 12 months, and only if the landlord’s notice included the required disclosure of that right.

When can a Massachusetts landlord charge a late fee? Not before rent is a full 30 days past due — the longest mandatory wait in this state family, and the lease can’t shorten it.
