Sample Security Deposit Demand Letter for Maryland (2026)

If your Maryland landlord is sitting on your security deposit, a written demand letter is the step that usually gets it back — and Maryland's statute hands that letter two separate weapons: a forfeiture rule with no preconditions at all, and an up-to-treble penalty with attorney's fees stacked on top.

This guide shows you a complete sample demand letter for Maryland, explains the deadline in Md. Real Property § 8-203, covers the forfeiture-then-treble structure that most template letters get backwards — and walks through the interest your deposit has been quietly earning the whole time.

Maryland's 45-Day Rule (§ 8-203)

Under Md. Real Property § 8-203, your landlord has 45 days after your tenancy ends to return your security deposit — with any accrued interest — along with a written, itemized list of any deductions.

Both halves matter. The money and the written list are separate duties, and the list has its own consequence, which is where Maryland gets interesting.

One scope note before counting days: if you were evicted or abandoned the unit, § 8-203(h) puts you under different mechanics — the ordinary return rules don't apply, and you must send the landlord a written demand for the deposit within 45 days, after which the landlord's obligations run from your demand. A demand letter serves as exactly that. The sample below assumes a normal move-out at the end of the tenancy; if your exit was an eviction or abandonment, your letter needs the § 8-203(h) framing instead.

The Forfeiture Rule — No Preconditions

Here's the part of § 8-203 that most template letters bury under the flashier treble-damages language, and it's the stronger of the two.

A landlord who fails to send the required written list of damages within the 45 days forfeits the right to withhold any part of the deposit for damages. No willfulness requirement. No bad-faith showing. No "reasonable basis" test. The missed list, by itself, ends the landlord's ability to keep your money for claimed damage.

By the time you're writing a demand letter, the 45 days have usually run with no list in sight — which means you're not writing to argue about whether the carpet charge was fair. You're writing to point out that the landlord's window to claim damages at all has already closed. That's the argument to lead with, because it's unconditional.

The Treble Penalty — the Escalation

On top of forfeiture, § 8-203 exposes the landlord to real damages: a landlord who, without a reasonable basis, fails to return the deposit within 45 days is liable for up to three times the withheld amount, plus reasonable attorney's fees.

So a $1,500 deposit wrongfully withheld can support a court judgment of up to $4,500 plus fees. The fee provision changes the economics entirely — Maryland tenant attorneys will take deposit cases, because the landlord ends up covering the bill.

Note the structure, because it's how a credible Maryland letter is built: the forfeiture is automatic on a missed list; the treble has a precondition — the withholding must lack a reasonable basis, and the "up to" means the court sets the multiple. The letter that works asserts forfeiture at full strength and states the treble-plus-fees exposure as what the landlord walks into by continuing to withhold. Templates that shout "you owe me triple" as if it were automatic have the statute backwards.

The Interest Your Deposit Has Been Earning

Maryland deposits of $50 or more held at least six months must earn simple interest at the greater of the daily U.S. Treasury one-year yield curve rate or 1.5% per year, accruing monthly — and § 8-203 requires the deposit to come back with that interest.

One trap to avoid: older sources still cite a flat 3% figure. That number is stale — citing it in a letter tells the landlord's attorney the letter was built from an outdated template. Demand the deposit "with accrued interest as provided by § 8-203" and let the statute's current formula do the math.

The Deposit Cap Changed in 2024

For leases signed on or after October 1, 2024, Maryland caps security deposits at one month's rent — down from the long-standing two months. Leases signed before that date remain under the two-month maximum, and where the tenant uses a utility- or housing-assistance program the cap can be up to two months.

This has teeth: charging more than the applicable cap exposes the landlord to up to threefold the excess, plus fees. If your lease post-dates October 2024 and your landlord collected more than a month, that's a second claim riding in the same letter.

Sample Maryland Security Deposit Demand Letter

Here's what a properly structured Maryland demand letter looks like — laid out the way an actual demand letter reads on paper. The scenario: the tenant's lease ended and she handed back the keys June 15, and the landlord has sent nothing — no refund, no itemized list — for over six weeks.

Notice what this letter does — and doesn't do:

• It leads with forfeiture, not the treble. The missed 45-day list forfeits the right to withhold for damages, with no preconditions — so the letter asserts that outcome as already fixed, and states the up-to-treble-plus-fees exposure as the escalation the landlord walks into by continuing to withhold. That's the statute's actual structure.
• It keeps the treble honest. "Up to threefold," conditioned on the lack of a reasonable basis — stated as the exposure the statute creates, not as an automatic entitlement. The landlord's own attorney will confirm both halves.
• It demands the interest. The deposit comes back with accrued interest under § 8-203 — a line most template letters simply forget — without citing any stale flat-rate figure.
• It closes the side doors. Stating that no rent or fees are owed and that the unit's condition is documented with photographs and a checklist removes the two excuses landlords reach for first.
• It supplies the forwarding address in writing, so there's never an argument about where payment was due.
• It sets a real deadline and states the consequence — court — while leaving the door open to simply paying.

How to Send It

Send the letter by USPS Certified Mail with Return Receipt. This creates dated, third-party proof that the landlord received your demand — the exact kind of evidence a small claims judge asks about first. Keep the tracking number, the return-receipt confirmation, and a copy of the signed letter. (Full walkthrough: how to send a demand letter by certified mail.)

Then wait out the deadline you set. If the landlord pays, you're done. If not, the letter plus the certified-mail receipt become the backbone of a court case built on Maryland's cleanest fact pattern: the list never came, the forfeiture attached, and § 8-203 puts your attorney's fees on the landlord's tab.

Frequently Asked Questions

How long does a landlord have to return a security deposit in Maryland? 45 days after the end of the tenancy. Within that window the landlord must return the deposit with any accrued interest, along with a written, itemized list of any damages and deductions.

What happens if my landlord doesn't return my deposit in 45 days? A landlord who fails to send the required written list of damages within 45 days forfeits the right to withhold any part of the deposit for damages. And a landlord who without a reasonable basis fails to return the deposit is liable for up to three times the withheld amount plus reasonable attorney's fees.

Is the treble penalty automatic in Maryland? No — it applies where the landlord withheld without a reasonable basis, and "up to" threefold means the court sets the amount. The forfeiture rule, by contrast, has no preconditions: a missed damage list by itself ends the landlord's right to withhold for damages. A well-built Maryland letter leads with forfeiture.

Does Maryland pay interest on security deposits? Yes — deposits of $50 or more held at least six months earn simple interest at the greater of the daily U.S. Treasury one-year yield curve rate or 1.5% per year, accruing monthly, and the deposit must be returned with that interest. Older sources citing a flat 3% are out of date.

How much can a landlord charge for a security deposit in Maryland? One month's rent for leases signed on or after October 1, 2024 (two months for earlier leases, and up to two months where the tenant uses a utility- or housing-assistance program). Charging above the cap exposes the landlord to up to threefold the excess plus fees.

I was evicted — do the same rules apply? Not exactly. Under § 8-203(h), the ordinary return rules don't apply to a tenant who was evicted or abandoned the premises — that tenant must send the landlord a written demand for the deposit within 45 days, and the landlord's obligations run from the demand. A demand letter serves as that written demand.
