Maryland Security Deposit Law 2026: Limits, Deadlines & Deductions

Maryland caps most deposits at one month's rent, requires the money to sit in a federally insured Maryland account, and gives you 45 days after the tenancy ends to return the deposit plus interest with an itemized list sent by first-class mail. Withhold without a reasonable basis and the exposure is up to three times the amount withheld plus attorney's fees. The inspection, receipt, and estimate rules in §8-203 and §8-203.1 are where most Maryland cases are actually won and lost. Every section below summarizes Maryland Code, Real Property Article §8-203 and §8-203.1 in plain language.

The short version: Charge no more than one month's rent, with one narrow exception described below. Give the statutory receipt, deposit the funds within 30 days into an in-state federally insured account devoted exclusively to deposits, and honor the tenant's move-out inspection rights. Within 45 days after the tenancy ends, return the deposit plus simple interest (deposits of $50 or more held at least 6 months, at the greater of the 1-year Treasury yield rate or 1.5% per year), less damages rightfully withheld, and mail the written damage list with an itemized statement of costs to the tenant's last known address. Miss the list and you forfeit the right to withhold for damages.

Corrections to the earlier version of this page: The cap is not a simple pre/post October 2024 split. The current statute sets a one-month ceiling with a single exception — up to two months only when the tenant qualifies for Department of Human Services utility assistance, the lease requires the tenant to pay the landlord directly for utilities, and both sides agree in writing. The treble-damages rule for a missed return sits in §8-203(e)(4), not (g)(2); subsection (g)(2) is the forfeiture rule for a missing damage list. Estimates are also no longer flatly barred: subsections (j) and (k) allow an estimate to support the itemized statement, provided you later send the final invoice and refund any excess over actual cost. The receipt contents and the 2-year retention duty live in §8-203.1, not §8-203 itself.

Maryland's 45-day deadline, first-class-mail list rule, and estimate true-up duty mean paperwork wins or loses your whole deposit. The Security Deposit Disposition & Deadline Tracker ($14.95) keeps your return deadlines, itemized deductions, and mailing dates in one spreadsheet so the clock never sneaks up on you.

The statute table

Limits: how much can you charge?

One month's rent is the ceiling (§8-203(b)(1)). The only route to two months is the three-part test in §8-203(b)(2): the tenant is eligible for and has qualified for utility assistance through the Department of Human Services, the lease requires the tenant to pay for utility services directly to the landlord, and the tenant and landlord agree in writing to the higher amount. If any leg is missing, the cap is one month. Charging more exposes you to up to three times the extra amount plus attorney's fees, in an action the tenant may bring during the tenancy or within two years after it ends (§8-203(b)(3)–(4)). Verify your figure with the Security Deposit Max Checker.

The 45-day deadline, precisely

Within 45 days after the end of the tenancy, return the deposit plus simple interest, less damages rightfully withheld (§8-203(e)(1)). In that same window, if you withheld anything, mail by first-class mail to the tenant's last known address a written list of the damages claimed together with an itemized statement of the costs incurred (§8-203(g)(1)). Fail to send the list and you forfeit the right to withhold any portion for damages (§8-203(g)(2)) — the deposit comes back whole even if the charges were real. Calendar it with the Security Deposit Deadline Finder.

When the clocks actually start

Maryland runs three distinct clocks. The standard return clock runs 45 days from the end of the tenancy, regardless of when you inspect or when the tenant hands over a forwarding address — the statute keys the mailing duty to the last known address. The eviction/abandonment clock is different: subsections (e) and (g) do not apply to a tenant evicted for breach or who abandoned before the term ended; instead that tenant must demand return by written notice mailed within 45 days of the eviction or abandonment, stating a new address, and your 45 days then run from receipt of that demand (§8-203(h)). The estimate clock starts only if you used an estimate under subsection (j): when the repairs are completed you must notify the tenant in writing with the final invoice, and any amount withheld above the actual cost is due back within 30 days after completion (§8-203(k)). Log three dates in the deposit file: the tenancy-end date, the mailing date of the return and list (with proof), and — if an estimate was used — the repair-completion date.

A worked example

Say rent is $1,500 a month and the deposit is $1,500 — lawful, at the one-month cap. The tenancy ends on Monday, March 2, 2026. The 45-day return and list deadline is Thursday, April 16, 2026. You inspect with the tenant present (the tenant sent the certified-mail notice in time), find $650 in proper charges, and owe a $850 balance plus accrued interest. By April 16 you mail both the balance and the written list with the itemized statement of costs to the tenant's last known address. Suppose instead you supported one $650 charge with an estimate and the actual repair cost came in at $500: once the work is finished you must send written notice with the final invoice and refund the $150 excess within 30 days after completion. And if April 16 passes with no list at all, §8-203(g)(2) forfeiture applies — the $650 is no longer yours to keep, however well documented it was.

Deductions and the itemized list

Withhold only for (§8-203(f)(1)(i)):

1. Unpaid rent;

2. Damage due to breach of lease; and

3. Physical damage beyond ordinary wear and tear caused by the tenant or the tenant's family, agents, employees, guests, or invitees.

The deposit is not a penalty fund: it is not liquidated damages and may be retained only to the extent you were actually damaged, and any rent you actually collect for the remainder of the term reduces lost-rent damages dollar for dollar (§8-203(f)(2)–(3)). The itemized statement must be backed by documentation identifying the materials or services provided; an estimate can serve as that documentation, but it triggers the final-invoice and refund duties in subsection (k) (§8-203(j)–(k)). Build the compliant letter with the Security Deposit Deduction Letter Generator.

Move-out inspection and the receipt

Two paperwork duties bookend the tenancy. At the start, the receipt — which must be included in the written lease — has to notify the tenant of the move-in inspection right, the move-out inspection right, the 45-day list and return duties, and the treble-damages penalty (§8-203.1(a)). Keep a copy of that receipt for two years after the tenancy ends, the premises are abandoned, or the tenant is evicted; failing to provide the receipt at all carries a $25 liability (§8-203.1(b)–(c)).

At the end, the tenant may be present at your move-out inspection by notifying you by certified mail at least 15 days before the moving date, stating the move date and new address. You must then notify the tenant by certified mail of the inspection date and hold the inspection within five days before or after the stated move date. The tenant must be told of these rights in writing when the deposit is paid — and a landlord who skips this process forfeits the right to withhold any part of the deposit for damages (§8-203(f)(1)(ii)–(vii)).

Move-out compliance checklist

1. Give the full §8-203.1 receipt in the lease on day one. It must list both inspection rights, the 45-day duties, and the treble penalty; file your copy for the 2-year retention period.

2. Deposit the money within 30 days. Use a federally insured institution doing business in Maryland, an in-state branch, an account devoted exclusively to deposits (§8-203(d)(1)).

3. Honor the inspection notice. If a certified-mail notice arrives 15 or more days before the move, reply by certified mail and inspect within 5 days either side of the move date, with the tenant entitled to attend.

4. Log the tenancy-end date and count 45 days. That single date drives both the return and the mailing of the damage list; for an eviction or abandonment, watch instead for the tenant's written demand.

5. Itemize with documentation, not just totals. Each charge needs a cost and supporting documentation identifying the materials or services; flag any figure that is still an estimate.

6. Mail the list and the balance together, first-class, to the last known address. Keep the mailing proof with the deposit file — the mailing, inside the window, is the compliance act.

7. Close out estimates. When estimated repairs finish, send the written completion notice with the final invoice and refund any excess withheld within 30 days (§8-203(k)).

Interest and where the money sits

• Where it sits: a federally insured financial institution that does business in Maryland, in a branch located in the state, in an account devoted exclusively to security deposits and bearing interest — or, instead, insured certificates of deposit or federal or Maryland securities of equal aggregate value (§8-203(d)(1)–(2)). The aggregate must always equal all deposits you are liable for, and the money may not be attached by your creditors or the tenant's.
• Receipt required: the §8-203.1 receipt described above, included in the lease; no receipt means a $25 liability.
• Interest required: simple interest, never compounded, accruing at monthly intervals from the day the tenant pays, on deposits of $50 or more held at least 6 months (no interest for a partial month), at the greater of the daily 1-year U.S. Treasury yield curve rate as of the first business day of the year or 1.5% per year (§8-203(e)). The Department of Housing and Community Development maintains the official rate list and a calculator on its website, and a landlord is entitled to rely on them (§8-203(m)–(n)). Run your own numbers with the Security Deposit Interest Calculator.

The penalty, spelled out

Maryland stacks three separate sanctions:

• No itemized list within 45 days (or a skipped inspection process) → forfeit the right to withhold any portion for damages (§8-203(g)(2), (f)(1)(vii)). Legitimate charges are lost with the paperwork.
• Failure, without a reasonable basis, to return any part within 45 days → the tenant's action for up to three times the amount withheld, plus reasonable attorney's fees (§8-203(e)(4)). The same treble measure applies on the eviction/abandonment demand track (§8-203(h)(3)(ii)).
• Overcharging the cap → up to three times the extra amount charged, plus fees (§8-203(b)(3)).

Run the worked example through the (e)(4) formula. If the $650 in charges was withheld without a reasonable basis, treble exposure on that portion is $1,950, plus fees. If the entire $1,500 deposit had been withheld without a reasonable basis, the figure is $4,500, plus the tenant's attorney's fees. The forfeiture rule is priced differently — it does not multiply anything; it simply takes the withheld amount itself away.

FAQ

How long does a Maryland landlord have to return a security deposit?

45 days after the end of the tenancy, with interest, and the written damage list with an itemized statement of costs mailed by first-class mail to the tenant's last known address in the same window (§8-203(e)(1), (g)(1)).

What is the maximum security deposit in Maryland?

One month's rent. Up to two months is allowed only when the tenant qualifies for Department of Human Services utility assistance, the lease requires the tenant to pay the landlord directly for utilities, and both parties agree in writing (§8-203(b)(1)–(2)).

Does Maryland require interest on security deposits?

Yes — on deposits of $50 or more held at least 6 months: simple interest, accruing monthly and never compounded, at the greater of the 1-year Treasury yield curve rate as of the first business day of the year or 1.5% per year (§8-203(e)).

What happens if the landlord doesn't send the itemized list?

The landlord forfeits the right to withhold any portion of the deposit for damages (§8-203(g)(2)).

Can a Maryland landlord use an estimate in the itemized statement?

Yes, as supporting documentation under §8-203(j)(2) — but the landlord must then notify the tenant in writing when the repairs are completed, include the final invoice, and refund any amount withheld above the actual cost within 30 days after completion (§8-203(k)).

What is the penalty for withholding a Maryland deposit without a reasonable basis?

Up to three times the amount withheld, plus the tenant's reasonable attorney's fees (§8-203(e)(4)).

Does the tenant have a right to attend the move-out inspection in Maryland?

Yes — if the tenant notifies the landlord by certified mail at least 15 days before moving, with the move date and new address. The landlord must reply by certified mail and inspect within 5 days before or after that date; skipping the process forfeits withholding for damages (§8-203(f)(1)).

What changes if the tenant was evicted or abandoned the unit?

The standard 45-day duties do not apply directly. The tenant must demand return in writing within 45 days of the eviction or abandonment, stating a new address; the landlord then has 45 days from receiving the demand to send the damage list and return the balance with interest (§8-203(h)).

Read the statute yourself

Everything on this page traces back to Md. Real Property Code §8-203 and §8-203.1. If a deadline, a deduction, or a penalty is ever disputed, the primary sources — not a summary — are what control:

• Md. Real Prop. §8-203 (Maryland General Assembly, official) — the cap, account, interest, return, inspection, and penalty rules.
• Md. Real Prop. §8-203 (Justia) — the same full text in Justia's 2025 Maryland Code.
• Md. Real Prop. §8-203.1 (Justia) — the required receipt contents, the 2-year retention duty, and the $25 no-receipt liability.
• Md. Real Prop. §8-203 (Cornell LII) — the same deposit text in Cornell's annotated code.

Maryland's one-month cap, 45-day return deadline with interest, first-class-mail list rule, and treble-damages penalty for withholding without a reasonable basis mean paperwork wins or loses your whole deposit. The Security Deposit Disposition & Deadline Tracker ($14.95) keeps your return deadlines, itemized deductions, and mailing dates in one spreadsheet so the clock never sneaks up on you.
