Your building changed hands during your tenancy, and now the lease in your drawer names a company that no longer owns the place, and nobody can tell you where your security deposit went.
In Massachusetts, that deposit was supposed to travel with the building. The new owner becomes responsible for it, and they were required to tell you so in writing.
If that didn't happen, you're looking at a specific failure that the law names, and in several cases attaches a specific remedy to.
Your deposit is supposed to travel with the building
When a rental property in Massachusetts changes hands, the deposit doesn't stay behind with the old owner and it doesn't evaporate in the paperwork. The statute is explicit about where it goes and who becomes answerable for it.
Under M.G.L. c.186 § 15B(5), a landlord who transfers the property must pass on the security deposit "together with any interest which has accrued thereon" to the successor in interest. That successor is "liable for the retention and return of said security deposit… from the date upon which said transfer is made", and must "within forty-five days from the date of said transfer, notify the tenant" that the deposit was transferred to them. Under § 15B(7A), the same transfer-and-45-day-notice rule applies to last month's rent.
Your money was supposed to move. Not be applied to something. Not be absorbed into the sale. Transferred, with the interest it had earned.
The new owner inherited the obligation. They are liable for holding and returning it from the transfer date onward, regardless of whether the previous owner actually handed it over.
Somebody owed you a letter. Within 45 days of the transfer, in writing. If you never got one, that on its own is a failure of the rule, and it's often the first sign that the rest went wrong too.
Which failure actually happened?
This matters more than it might seem, because Massachusetts doesn't treat every deposit failure the same way. Some carry a substantial statutory remedy; one common failure doesn't. Find the row that matches your situation.
| What went wrong | Which duty was missed | What the statute provides |
|---|---|---|
| Nobody told you the building had changed owners | The successor's notice duty — § 15B(5) | Written notice was required within 45 days of the transfer |
| Your deposit was never handed to the new owner | § 15B(6)(d) — failure to transfer to the successor | Treble damages under § 15B(7) — plus 5% interest, court costs and attorney's fees |
| No itemized list of damages within 30 days of move-out | § 15B(6)(b) | A violation — but not one of the treble-damages clauses. See our guide to itemized receipts and deposit rights |
| Deposit not returned within 30 days of the tenancy ending | § 15B(6)(e) | Treble damages under § 15B(7) |
| Deposit was never held in a separate interest-bearing account | § 15B(6)(a) — failure to deposit funds as required | Treble damages under § 15B(7) |
The 30-day itemized-list requirement is probably the deposit rule renters have heard of most, and failing to provide it is a violation, but it sits outside the group that carries the enhanced remedy. Anyone telling you that any deposit violation automatically earns three times your money is overstating it.
What the law provides when they get it wrong
For failures under clauses (a), (d) and (e) (the account, the transfer, and the 30-day return), § 15B(7) provides that the tenant "shall be awarded damages in an amount equal to three times the amount of such security deposit or balance thereof," plus interest at five per cent from the date the payment became due, together with court costs and reasonable attorney's fees.
That fee-shifting detail changes the practical picture. Court costs and reasonable attorney's fees are part of the remedy. That's why a case that would otherwise be uneconomic (nobody hires a lawyer at $300 an hour to chase $1,000) is one that some attorneys will take on a contingency basis. The fee-shifting is built into the statute rather than depending on your ability to pay up front.
What this does not mean is that your particular situation is a guaranteed win. Whether a specific failure occurred, and which clause it falls under, depends on facts a general article can't see. The statute tells you what's on the table. It doesn't tell you that you'll collect it.
What to gather before you do anything
Whatever route you take, it runs on documents. Assemble these first. Most of them are easier to get now than in three months.
Proof you paid it
Bank statements showing the money leaving your account, a canceled check, a money-order receipt, or the lease clause recording the amount. A deposit that can't be evidenced is a much harder conversation, and "they know I paid it" isn't evidence.
The bank notice and interest statements you should have received
A Massachusetts landlord holding a security deposit is required to keep it in a separate account and to account for the interest it earns. If you were never told which bank held your money, and never received a statement of interest, note that. That's a § 15B(6)(a) failure, the separate-account rule, and it's independently significant.
Move-out evidence
Photographs and video of the unit as you left it, with dates. If you're reading this before moving out, do this even if you have no reason to expect trouble. It costs ten minutes and it is the single most useful thing you can hold. Where a charge is being made for wear on flooring or paint, dated images of the actual condition are worth more than any argument about what counts as normal.
Your lease, and the name on it
Find the lease and note exactly which entity signed it. In a building that has changed hands, the name on your lease and the name of the current owner are frequently different, and working out who to address is the first practical problem, not a detail.
Where this gets complicated — and where to get help
Three parts of this genuinely can't be resolved from a general guide, and a reader in any of them should get advice rather than proceed on a blog post.
When the entity on your lease no longer exists. Buildings are often held by single-purpose companies that are wound up after a sale. The statute makes the successor liable from the transfer date, but pursuing a deposit when the original signatory has dissolved raises questions about who you actually name and how, and that is a question for someone who can look at your paperwork.
Foreclosure rather than an ordinary sale. Section 15B(5) exempts a foreclosing mortgagee, or a mortgagee in possession that is a bank chartered by Massachusetts or the United States, from the successor liability described here. If a lender took your building through foreclosure, don't assume the transfer rules in this article apply to your deposit.
Whether your facts fit a particular clause. The table maps failures to provisions in the ordinary case. Yours may be ordinary. It may not be.
For free, Massachusetts-specific help, Mass Legal Help is a good first stop, and the Massachusetts Attorney General's consumer division takes complaints about this kind of dispute. A tenant-rights attorney or a local housing organization can tell you what your paperwork actually supports. And given the fee-shifting provision, an initial conversation may cost less than you'd expect. Small claims court exists for disputes of modest size, though whether it's the right venue for yours is again a question worth asking someone.
There is also a separate consumer-protection statute in Massachusetts, chapter 93A, that renters in deposit disputes are often pointed toward. It's worth raising with whoever advises you; we're not going to describe how it works here, because getting the mechanics of it right matters more than mentioning it.
FAQ
What happens to my security deposit if my building is sold? It's supposed to transfer to the new owner along with any interest it has earned. Under M.G.L. c.186 § 15B(5) the new owner (the "successor in interest") becomes liable for holding and returning it from the date of transfer, and must notify you within 45 days that it was transferred to them.
Does my last month's rent transfer too? Yes. Section 15B(7A) applies the same transfer obligation and the same 45-day notification requirement to last month's rent paid in advance.
Nobody told me the building changed owners. Is that a problem? The successor was required to notify you in writing within 45 days of the transfer. Not receiving that notice is a failure of the rule, and it's often the first indication that the deposit itself wasn't handled properly either.
Can I get three times my deposit back? Treble damages under § 15B(7) apply to failures under clauses (a), (d) and (e) — not holding the deposit in a proper account, not transferring it to the successor, and not returning it within 30 days of the tenancy ending. They come with 5% interest, court costs and reasonable attorney's fees. Whether your situation qualifies depends on your facts.
My landlord never sent an itemized list of damages. Does that get me treble damages? That failure falls under clause (b), which is a violation but is not one of the clauses carrying the treble remedy. It still matters, and it's worth raising. Just don't rely on it for the enhanced damages.
Who do I pursue when my lease names a company that no longer owns the building? The successor is liable from the transfer date, but if the original entity has been dissolved the question of who to name and how gets complicated quickly. This is the main reason to get advice rather than filing on your own assumptions.
What should I have kept? Proof you paid the deposit, any notice telling you which bank held it, statements of the interest it earned, dated photos or video from move-out, and your lease with the signing entity's name.
