Massachusetts Security Deposit Demand Letter (Sample Letter + Guide)

A Massachusetts demand letter is a record-building step

If you are looking for a Massachusetts security deposit demand letter, you are in the right place.

This page gives you a copy-and-use demand letter for Massachusetts, along with what it should include, when to send it, and what to do next.

If your landlord has not returned the security deposit or balance within 30 days after the tenancy ends, or if deductions were claimed without the sworn itemized statement and supporting documents Massachusetts requires, this is usually the point where a simple written demand helps move things forward. See the 30-day deadline rule for how timing works in Massachusetts.

You can use the sample below as-is. Just remember: one letter alone is often not enough if you do not keep proof, track the deadline, and know what to send next.

DepositBackUSA is built around that sequence. The Massachusetts Recovery System puts the letters, timing, documentation, and follow-up steps in one place so you do not have to piece it together while dealing with the landlord.

When to Use a Security Deposit Demand Letter

Use this letter if:

• You moved out of a rental in Massachusetts
• More than 30 days have passed since the tenancy ended
• You have not received the security deposit or balance due
• You received no compliant sworn itemized statement with supporting written evidence
• You want to make a clear written request before taking the next step

Under the Massachusetts source used on this site, a landlord generally must return the security deposit or balance within 30 days after termination of occupancy under a tenancy-at-will or the end of the tenancy as specified in a valid written lease.

Damage deductions require a sworn itemized statement under pains and penalties of perjury, with supporting written evidence such as estimates, bills, invoices, or receipts.

Do not send the letter as a vent. Send it as a clean record: facts, amount requested, deadline, and proof of delivery.

Sample Security Deposit Demand Letter

You can copy this sample security deposit demand letter, fill in your details, and send it yourself.

[Your Name] [Your Current Address] [City, State, ZIP] [Email Address] [Date]

[Landlord's Name] [Landlord's Address]

Re: Security Deposit for [Rental Address]

Dear [Landlord's Name],

I am writing regarding the security deposit for the rental property at [Rental Address], where my tenancy ended on [Tenancy End Date].

Under Massachusetts security deposit law, including M.G.L. c. 186, section 15B, a landlord generally must return the security deposit or balance within 30 days after the tenancy ends. If money is withheld for damage, Massachusetts requires a sworn itemized statement and supporting written evidence.

More than 30 days have now passed, and I have not received my security deposit / the balance due / a compliant sworn itemized statement with supporting written evidence.

Please return the amount due of $[Amount], including any required interest, or provide a compliant sworn accounting with supporting documents, within [Insert Response Deadline].

If I do not receive a response, I may pursue the remedies available under Massachusetts security deposit law.

Please send any payment and correspondence to the address listed above.

Sincerely, [Your Name]

The next step is usually where things get unclear

The letter itself is straightforward.

What tends to slow things down is what comes after:

• how long to wait
• what to send next
• when to escalate
• how to keep the paper trail clean if the landlord ignores you or sends weak deductions

You can figure that out yourself, it just takes time to piece together the timing, follow-ups, and escalation steps.

The Massachusetts Recovery System is the shortcut for that part. It is not a gatekeeper and it is not legal advice. It is the 4-step sequence already organized: prevention, first demand, stronger follow-up, and final demand before escalation.

How to Use This Sample Letter

A security deposit demand letter does not need to be complicated.

The goal is to make a clear written request that shows:

• when the tenancy ended
• how much the deposit was
• that the 30-day period has passed
• whether required interest was included
• what you are asking for
• when you expect a response

Keep it short. Keep it factual.

A simple letter like this works in many cases.

If it does not, the value of the letter is still real: it shows when you made the demand, what you asked for, and how the landlord responded or failed to respond.

What to Include

Include the basic facts that matter:

• your full name
• the rental address
• the tenancy end date
• the amount of the deposit
• whether required interest was included
• your forwarding address
• your email or phone number
• a short deadline for response

If you have them, it also helps to keep copies of:

• move-out photos
• your lease
• proof of rent or deposit payment
• any statement-of-condition records
• the sworn itemized statement and supporting documents, if any
• text messages or emails with the landlord

How to Send It

It is usually best to send the letter in a way you can document later.

A practical approach is:

1. Send it by certified mail This gives you proof that it was sent and delivered

2. Send the same letter by email if you have the address This creates an additional record

3. Keep copies of everything Save the letter, email, mailing receipt, and any response

What Happens After You Send It

In many cases, one of two things happens.

The landlord sends the deposit

Sometimes a formal written request is enough.

The landlord responds with deductions

If that happens, review whether the deductions fit Massachusetts' rule and whether the sworn itemized statement and supporting evidence are actually compliant. See what landlords can deduct.

The landlord ignores the letter

If there is still no response, the next step is usually to consider filing in court or another appropriate forum. See the small claims guide.

The letter creates a clear record. What happens next usually depends on timing and follow-up, not just the first letter itself.

That is why the system uses a sequence instead of treating the first demand as the whole strategy.

Common Mistakes to Avoid

• waiting too long after the 30-day deadline has passed
• sending only informal messages instead of a real letter
• forgetting to include the tenancy end date
• not checking whether required interest was included
• not demanding the sworn itemization and supporting written evidence Massachusetts requires

A clean, direct letter works better than a long emotional one.

A Quick Note on Deductions

A lot of deposit disputes come down to deductions.

Under the Massachusetts source used on this site, a landlord may deduct only:

• unpaid rent or water charges
• unpaid tax-escalation increases allowed by law
• reasonable repair costs for tenant-caused damage beyond reasonable wear and tear

Massachusetts also requires sworn itemization and supporting written evidence for damage deductions.
