Maryland Security Deposit Laws: The New One-Month Cap, 45-Day Return, and 3x Penalty

Maryland security deposit law is set almost entirely by one statute — Real Property, Section 8-203 — and it changed in a big way on October first, 2024. The Renters’ Rights and Stabilization Act of 2024 cut the maximum deposit to a single month’s rent for new leases, replacing the old two-month limit that many leases and online guides still repeat. This guide walks the whole Maryland framework end to end: how much you may collect now, what you can and cannot deduct, the forty-five-day return deadline, the itemized list of damages, the deposit receipt and the tenant’s move-in and move-out inspection rights, the interest a landlord must pay, and the penalty a court can impose when a landlord keeps a deposit without a reasonable basis.

Whether you own one rowhouse or a small portfolio, the rules below apply the same way, because Real Property, Section 8-203 governs statewide. What varies is the local rental market and a handful of county-level rules layered on top of the state framework. Everything here is general information, not legal advice; confirm the current figures and consult a licensed Maryland attorney before acting on a specific dispute.

Below, a short overview video summarizes the Maryland deposit rules; the sections that follow break down each piece in detail — the new cap and its utility-assistance exception, deductions versus normal wear and tear, the return timeline, the receipt and inspection rights, interest, penalties, the move-out walkthrough, and the small-claims path if a dispute cannot be resolved.

The single most important thing to know is that Maryland’s deposit cap dropped. For decades, Real Property, Section 8-203 let a landlord collect up to two months’ rent as a security deposit. The Renters’ Rights and Stabilization Act of 2024 changed that. For any lease signed on or after October first, 2024, the maximum security deposit is one month’s rent. If your lease template, your management software, or an older guide still says two months, it is out of date — and charging the old amount on a new lease is now a live legal error that can expose you to a refund claim and, potentially, the statutory penalty.

How Maryland Defines a “Security Deposit” — and Why You Cannot Stack

Real Property, Section 8-203 defines a security deposit broadly: any payment of money a tenant gives the landlord to protect against nonpayment of rent, damage to the leased premises, or breach of the lease. That broad definition is what gives the one-month cap its teeth. A landlord cannot get around the cap by relabeling money — collecting one month’s rent as a “deposit” plus a separate “move-in fee,” “last month’s rent held as security,” or “non-refundable pet deposit” that together exceed one month’s rent runs into the same cap, because those charges are all security deposits by definition. The safe rule is simple: everything you hold to protect yourself against unpaid rent or damage counts toward the one month.

The Utility-Assistance Exception

The 2024 Act kept one narrow carve-out. A landlord may collect up to two months’ rent as a deposit only if all of the following are met: the tenant qualifies for utility assistance through the Maryland Department of Human Services; the lease requires the tenant to pay utilities directly to the landlord; and the landlord and tenant agree in writing to the higher amount. A landlord who does not meet every part of that test is back to the one-month cap.

Real Property, Section 8-203 limits what a Maryland landlord may deduct from a security deposit. The landlord bears the burden of proving each deduction is legitimate, so anything not clearly on the list is presumed to be the landlord’s cost to absorb.

Permitted Deductions

• Unpaid rent. Rent that remains owed for the final month or any earlier period.
• Unpaid utility charges. Utility bills the tenant was responsible for that the landlord had to cover.
• Damage beyond ordinary wear and tear. Holes in walls, broken fixtures, pet-stained flooring, and similar damage the tenant or their guests caused — documented and beyond normal use.
• Other breaches that caused actual damages. Where the lease was breached and the landlord suffered a measurable, documented loss, such as unauthorized alterations left behind.

Not Deductible — Ordinary Wear and Tear

Ordinary wear and tear is the natural deterioration that happens from living in a unit normally, and the landlord must absorb it. Maryland treats these as non-deductible:

• Faded or lightly scuffed paint, and small nail holes from hanging pictures.
• Carpet worn thin along walkways from ordinary foot traffic, with no stains or pet damage.
• Minor marks, loose grout, or caulk that has aged around tubs and sinks.
• Worn but still-functioning appliances and fixtures that simply reached the end of their useful life.

The deadline Maryland landlords miss most often is the forty-five-day return rule. Under Real Property, Section 8-203, no later than forty-five days after the tenancy ends, the landlord must deliver two things: any remaining portion of the deposit, together with any interest owed, and a written list of the damages claimed along with an itemized statement of the cost of each. The clock runs from the end of the tenancy — when the tenant actually surrenders the unit — not from a date on the calendar the lease happened to name.

What the Itemized List Must Include

The statement must describe each item of damage claimed and the actual cost the landlord incurred to repair it. A vague line that reads “cleaning” or “painting” with a number and nothing behind it is not itemization; “professional pet-odor remediation, invoice attached, three hundred dollars” is. Attach invoices, receipts, or a documented cost basis for each charge. Keep in mind the landlord carries the burden of proof, so the more concrete the record, the safer the deduction.

The Forwarding Address and Where to Send the Return

A tenant makes the return smoother by giving a written forwarding address, and Maryland courts often treat that written address as the practical point from which the landlord sends the deposit and statement. If the tenant leaves no forwarding address, the landlord should mail the deposit and itemized list to the last known address — commonly the rental unit itself — and keep proof of mailing. Do not sit on the funds waiting for an address past the forty-five-day deadline; the obligation to send the statement on time still applies.

Two of the most overlooked features of Maryland law sit in the deposit receipt. Under Real Property, Section 8-203.1, the landlord must give the tenant a written receipt for the security deposit. A landlord who fails to give a receipt is liable to the tenant for twenty-five dollars. In practice, a lease that acknowledges the deposit and includes the required inspection-rights language satisfies the receipt requirement, which is the simplest way to comply.

The Move-In Inspection Right

A Maryland tenant has the right to a move-in inspection with the landlord to make a written list of damage that already exists at the start of the tenancy — but only if the tenant requests it by certified mail within fifteen days of taking occupancy. That baseline list protects both sides: it fixes the unit’s condition at move-in so pre-existing wear is never later charged to the tenant.

The Move-Out Inspection Right

A tenant also has the right to be present when the landlord inspects the unit at the end of the tenancy. To trigger it, the tenant must notify the landlord by certified mail at least fifteen days before the intended move date, stating the intention to move, the moving date, and a new address. The landlord must then conduct the inspection within five days before or after the stated move date and notify the tenant in writing of the inspection date. Honoring this right correctly, with the tenant present, documents the unit’s condition at surrender and heads off most disputes before they start.

Unlike some states, Maryland does require interest on security deposits, but only under specific conditions. Under Real Property, Section 8-203, a landlord must pay interest on a deposit of fifty dollars or more that the landlord has held for at least six months. Interest accrues at monthly intervals from the day the tenant pays the deposit, and it is not compounded. It is paid to the tenant at the end of the tenancy, along with the deposit and the itemized statement.

How the Rate Is Set

The interest rate is the greater of one and a half percent per year or the daily United States Treasury yield curve rate for one year, as of the first business day of each year. Because the Treasury component moves, the effective rate changes from year to year — in higher-rate years the Treasury figure controls, and in lower-rate years the one-and-a-half-percent floor does. The Maryland Department of Housing and Community Development publishes a calculator to help landlords compute the exact figure, and using it is the safest way to avoid underpaying. Because the number resets annually, treat the interest rate as a “check the current figure” item every time you calculate a return.

Maryland backs the deposit rules with real teeth. Under Real Property, Section 8-203, if a landlord fails to return the deposit without a reasonable basis, a court may award the tenant up to three times the amount wrongfully withheld, plus reasonable attorney’s fees. That threefold multiplier is on top of returning whatever was wrongfully kept.

Bad faith is not merely being wrong about a single deduction. It generally means the landlord acted without a reasonable basis — ignoring the forty-five-day deadline, inventing charges, refusing to itemize, or keeping the deposit with no legitimate justification. A landlord who returns the deposit and a clear itemized list on time, with support for each charge, is well protected even if a specific deduction is later disputed. The penalty exists to punish the landlord who treats the deposit as free money, not the one who makes a good-faith judgment call.

Put the rules together and the Maryland move-out becomes a repeatable checklist rather than a judgment call. Follow this sequence and penalty exposure all but disappears.

A thorough move-out record starts at move-in. Use a documented Maryland move-in and move-out checklist and photographs at both ends so you can prove exactly what the tenant caused. When you do withhold, a clean Maryland security deposit itemization form keeps the statement organized and defensible, and a Maryland security deposit return letter documents the return itself.

Most deposit disputes never reach a courtroom, but when they do in Maryland, they usually land in the District Court small claims docket — a forum designed to be used without a lawyer. An individual can sue for up to five thousand dollars in the Maryland small claims docket, which comfortably covers a deposit dispute and the threefold statutory multiplier in most cases. Verify the current limit, which the Legislature adjusts over time.

The pattern is consistent: Maryland deposit cases are won on paper. The landlord who documents condition at both ends, gives the receipt, offers the inspections, itemizes clearly, figures interest, and mails on time rarely loses — and the tenant who keeps their own photos and a copy of the written statement is equally well positioned to recover a wrongful withholding.

Beyond a routine move-out, a handful of situations trip up Maryland landlords because the deposit rules interact with other events. Three come up often.

When the Property Is Sold

If a landlord sells the rental, the security deposit obligation follows the property. In the ordinary case the seller transfers the remaining deposit — after any lawful deductions and with accrued interest — to the new owner, who becomes responsible for returning it under Real Property, Section 8-203, or the seller returns the deposit to the tenant with a full accounting. A landlord buying an occupied Maryland property should confirm in the closing that deposits, and the records showing when each was collected, are transferred and documented, because the buyer inherits the return obligation and the exposure to the threefold penalty.

Roommates and a Single Deposit

Where several tenants share a lease and a single deposit, Maryland treats the deposit as one sum tied to the tenancy, not as separate shares. When one roommate leaves and another stays, the landlord’s forty-five-day obligation is generally triggered only when the tenancy as a whole ends and the unit is surrendered — not each time one roommate moves out mid-lease. Sorting out each roommate’s share of a refund is usually a private matter among the tenants. Landlords should return the single deposit to the tenants collectively unless the lease or a written agreement directs otherwise, and avoid getting drawn into splitting it.

The Deposit Cap and a Rent Increase

The one-month cap is measured against the rent. If rent later rises, a landlord should not treat that as a license to demand more deposit to “top up” a deposit that was already lawfully collected on the existing lease. Landlords weighing a rent increase should review the separate rules that govern it — see our guide to Maryland rent increase laws — and should not use a permitted rent bump as a reason to collect a larger deposit from a sitting tenant. Set the deposit correctly at signing and leave it there.

Every rule above ultimately turns on proof. Maryland places the burden on the landlord to justify each deduction, which means the landlord who cannot document a charge loses it — regardless of whether the damage was real. Build the evidence file across the whole tenancy, not at the end.

At Move-In

• The deposit receipt with the required inspection-rights language, plus the move-in inspection list if the tenant requested it by certified mail.
• Timestamped photos or video of every wall, floor, fixture, and appliance, stored where the date cannot be doubted.
• A written note of any pre-existing wear, so it is never later charged to the tenant.

During the Tenancy

• A dated log of every maintenance request and the landlord’s response, which also rebuts a habitability defense — see Maryland habitability laws.
• Records of any lawful entry to inspect or repair, made with proper notice under Maryland entry rules — see Maryland landlord entry laws.

At Move-Out

• The written move-out inspection record, if the tenant sent the certified-mail notice and was present.
• A second set of timestamped photos taken at surrender, to compare against move-in.
• Invoices, receipts, or a documented in-house cost for every charge, attached to the itemized list.
• The interest calculation for a deposit held six months or more, and proof that the itemized statement and refund were mailed within forty-five days.

The cheapest deposit dispute is the one that never happens. A few disciplined habits protect a Maryland landlord across an entire portfolio.

• Document move-in exhaustively. A signed list and dated photos of every room create the baseline that decides every future deduction.
• Set the deposit at the current cap, and no higher. One month’s rent for most new leases, and two only if you genuinely qualify for the utility-assistance exception.
• Give the receipt and honor both inspection rights. The receipt costs nothing and skipping it costs twenty-five dollars and credibility; the inspections build a shared record of condition.
• Hold deposits in a protected, segregated account and track when each was collected, so you can figure interest correctly at return.
• Calendar the forty-five-day deadline at the end of the tenancy and mail the itemized list with proof, well before it expires.
• Screen carefully before you ever hand over keys. The tenants most likely to leave a unit in disputed condition are often the ones a thorough screening would have flagged.

That last point is where most disputes are actually won — before the lease is ever signed. A prior eviction, a pattern of damage, or unstable finances rarely appears out of nowhere; it usually leaves a trail an applicant’s history reveals. Screening for it is the single highest-leverage habit a Maryland landlord can build.
