For Maryland residential tenancies subject to the amended law, the security deposit cap is one month's rent per dwelling unit, regardless of the number of tenants. The Renters' Rights and Stabilization Act of 2024 halved the previous two-month ceiling, effective 1 October 2024. Leases entered into before that date should be reviewed separately, and the treatment of renewals executed after that date is worth confirming with Maryland counsel.

Here is what almost no guide mentions. The surety bond provisions in § 8-203(i) were not reduced. A surety bond purchased instead of a deposit may still be up to two months' rent, and where a tenant provides both a bond and a deposit, the aggregate may be up to two months. Maryland now runs a one-month deposit ceiling alongside a two-month bond ceiling, and the two are easy to confuse.

In short: One month's rent per dwelling unit, with a narrow three-condition exception allowing two months. Deposits go into a Maryland branch of a federally insured institution within 30 days, in an interest-bearing account used exclusively for deposits. Return within 45 days of the end of the tenancy with interest at the greater of the one-year Treasury yield curve rate or 1.5%. Section 8-203 contains multiple forfeiture rules and several provisions authorising damages of up to three times the amount at issue, depending on the violation. And no provision of the section may be waived in any lease.

Maryland deposit rules worth memorising

The cap: one month, per unit, with one three-part exception

Section 8-203(b)(1) provides that, except as provided in paragraph (2), a landlord may not impose a security deposit in excess of the equivalent of 1 month's rent per dwelling unit, regardless of the number of tenants.

Three points inside that sentence matter operationally.

"Per dwelling unit, regardless of the number of tenants." A four-bedroom house let to four individuals is one dwelling unit and one cap. Collecting a month's rent from each roommate is not permitted by the subsection.

"Impose." The verb matters, and Maryland's appellate courts have said so. In Ortiz Cerrato v. Garner, No. 301, Sept. Term 2022, the Appellate Court of Maryland held that a tenant's voluntary advance payment of rent meets the broad definition of a security deposit under § 8-203(a), but that a landlord does not violate the Act by accepting a tenant's voluntary advance payment, because liability is conditioned on the landlord's imposition or charging of a deposit above the maximum. Mere acceptance of advance rent did not suffice. The case concerned the earlier two-month ceiling, and the distinction it draws is between demanding and receiving.

That is a narrower proposition than the "anti-stacking" rule several guides state. The safe reading for a manager is that what you require is what is capped, and that structuring around the cap by requiring advance rent is exactly what the definition in subsection (a)(3) is designed to catch, since it expressly includes payment of the last month's rent in advance of the time it is due.

The exception is conjunctive. Under § 8-203(b)(2), a landlord may impose up to two months' rent only if the tenant is eligible and has qualified for utility assistance through the Department of Human Services; and the lease agreement requires the tenant to make payments for utility services directly to the landlord; and the tenant and landlord agree in writing to the amount. All three. The Maryland People's Law Library has published an editor's note correcting an earlier version of its own page that mistakenly rendered the second condition with an "or."

The penalty is treble the excess, not treble the deposit. Under (b)(3), a tenant may recover up to three times the extra amount charged, plus reasonable attorney's fees. And under (b)(4), an action may be brought at any time during the tenancy or within two years after its termination, so an over-collection on a 2024 lease can surface well into 2026.

Because the cap is per unit and the definition sweeps in advance rent and anything labelled a deposit, the lease template is where compliance is won. Maintaining one current Maryland template with the correct figure through contracts and renewals is what prevents an old two-month clause resurfacing on a renewal.

The trap: the bond ceiling did not move

This is the part the cap-reduction coverage misses.

Section 8-203(i) permits a tenant, instead of paying all or part of a security deposit, to purchase a surety bond. A landlord may not require the tenant to purchase one and is not required to consent to it.

The ceilings in that subsection are still expressed in two months:

• Under (i)(3)(i), the amount of a surety bond purchased instead of a deposit may not exceed two months' rent per dwelling unit.

• Under (i)(3)(ii), where a tenant purchases a bond and provides a deposit, the aggregate of both may not exceed two months' rent per dwelling unit.

Each carries its own treble-damages exposure for the excess, plus attorney's fees.

So a Maryland manager now has to hold two different numbers in mind: one month for what you may impose as a security deposit, and two months as the ceiling on a bond, or on a bond and deposit combined. Reading the second number as authority to collect a two-month deposit is the error waiting to happen.

On a sale or transfer, the bond travels with the tenancy. When a landlord's interest in the leased premises is sold or transferred, § 8-203(i)(11) requires the new landlord to accept the tenant's existing surety bond and restricts additional security during the current lease term. At renewal, the new landlord may not require a bond or deposit that, together with existing security, exceeds two months' rent per dwelling unit, with treble exposure on the excess.

The bond subsection carries several other duties worth knowing. A surety must make prescribed written disclosures before purchase, including that payment is nonrefundable and that the bond is not insurance for the tenant. At least 10 days before making a claim against a bond, the landlord must send the tenant a written list of the damages to be claimed and an itemized statement of costs. The tenant may pay damages directly or require the landlord to use the deposit first, and doing so forfeits the landlord's right to claim on the bond for that amount. The tenant may dispute the landlord's claim by sending a written response by first-class mail to the surety within 10 days after receiving the landlord's claim on the surety, and if disputed the surety may not report the claim to a credit reporting agency before obtaining a judgment against the tenant. A landlord who fails to comply forfeits the right to make any claim against the bond. And bonds may only be issued by an admitted carrier licensed by the Maryland Insurance Administration.

The receipt, and the two inspection rights it must describe

Section 8-203(c) requires the landlord to give the tenant a receipt for the deposit as specified in § 8-203.1, and § 8-203(c)(2) provides that the receipt shall be included in a written lease. That is mandatory, not optional. Section 8-203.1 then sets what the receipt must contain and attaches its own consequences.

Two obligations sit in § 8-203.1 that managers routinely miss. The landlord must retain a copy of the receipt for two years after the end of the tenancy. And a landlord who fails to provide the receipt is liable to the tenant for $25. That is a standalone penalty, independent of anything that happens to the deposit itself.

And the receipt must describe two different inspection rights, not one.

The initial inspection. Maryland gives a tenant the right to request an inspection by certified mail within 15 days of occupancy, for the purpose of making a written list, in the tenant's presence, of the damage that exists at the commencement of the tenancy. Most guidance discusses only the move-out inspection and omits this one.

The move-out inspection. Under § 8-203(f)(1)(ii)–(v), the tenant has the right to be present when the landlord inspects, if the tenant notifies the landlord by certified mail of the intention to move, the date of moving and the new address. That notice must be mailed at least 15 days prior to the date of moving. On receipt, the landlord shall notify the tenant by certified mail of the time and date of the inspection, and the inspection shall occur within five days before or five days after the moving date designated in the tenant's notice.

Then the provision that decides cases:

"(vi) The tenant shall be advised of the tenant's rights under this subsection in writing at the time of the tenant's payment of the security deposit.
(vii) Failure by the landlord to comply with this requirement forfeits the right of the landlord to withhold any part of the security deposit for damages."

That obligation attaches at the time the deposit is paid, typically at lease signing, long before anyone is thinking about move-out. Miss it, and the right to withhold for damages is gone regardless of how well the move-out is documented.

Because the trigger sits at signing and the consequence lands at move-out, this belongs in the lease packet rather than a move-out checklist. Dated condition evidence at both ends, captured through move-in and move-out management, is what supports the deduction once the notice requirement has been met, and it is also what an initial-inspection request produces.

Holding the money: 30 days, in-state, exclusive account

Section 8-203(d) is prescriptive and easy to breach without noticing.

The landlord shall maintain all security deposits in federally insured financial institutions which do business in the State. The accounts shall be maintained in branches located within the State, shall be devoted exclusively to security deposits, and shall bear interest. Each deposit must go into an account within 30 days after the landlord receives it, and the aggregate must equal all deposits for which the landlord is liable.

The alternative in (d)(2) is insured certificates of deposit at in-state branches, or securities issued by the federal government or the State of Maryland.

Three details a multi-state operator should check. The branch must be in Maryland, so a national operating bank relationship is not automatically sufficient. The account must be exclusive to deposits, so commingling with operating funds fails the subsection. And the 30 days runs from receipt, not from lease commencement.

On a sale, liability follows the accounting. Under (d)(3)(i), on sale or transfer including receivership or bankruptcy, the landlord or the landlord's estate, but not the managing agent or court appointed receiver, remains liable to the tenant and the transferee as to any portion of the deposit the landlord fails to deliver to the transferee together with an accounting showing the amount and date of the original deposit, the records of applicable interest rates, and the name and last known address of the tenant. Under (d)(4), any successor in interest is liable to the tenant for failure to return the deposit with interest.

That carve-out for the managing agent is worth noting if you are the agent rather than the owner. And under (d)(3)(ii), a deposit may not be attached by creditors of the landlord or of the tenant.

Forty-five days, interest, and the forfeiture rules

The return. Under § 8-203(e)(1), within 45 days after the end of the tenancy the landlord shall return the deposit together with simple interest, less any damages rightfully withheld.

The interest formula. Simple interest at the daily U.S. Treasury yield curve rate for 1 year, as of the first business day of each year, or 1.5% a year, whichever is greater. It accrues at monthly intervals from the day the tenant gives the deposit and is not compounded. No interest is due unless the landlord has held the deposit for at least six months, none accrues for any period less than a full month, and interest is payable only on deposits of $50 or more.

Two provisions make this manageable. Under (m), the Department of Housing and Community Development must maintain either a list of the annual rates or a customised calculator. Under (n), a landlord is entitled to rely on that list or calculator. Use the official DHCD Rental Security Deposit Calculator and record that you did.

The written list. Under (g)(1), if any portion is withheld, the landlord shall present by first-class mail to the last known address, within 45 days after termination, a written list of the damages claimed together with an itemized statement of the cost incurred. Under (j)(1), that itemized statement shall include supporting documentation that identifies the materials or services provided.

Estimates are allowed, with a follow-up obligation. Under (j)(2) a landlord may satisfy the documentation requirement with an estimate. But (k) then requires the landlord to notify the tenant in writing when the repairs have been completed, including a copy of the final invoice, and, where actual costs are less than the estimate, to return the excess within 30 days after completing the repairs. An estimate is not a way to close the file; it opens a second obligation.

Four forfeiture rules managers should know

Section 8-203 contains four provisions under which a landlord loses a right outright, separately from any damages the tenant may recover:

1. Failure to advise the tenant of the inspection rights required by § 8-203(f)(1)(vi) forfeits the right to withhold any part of the deposit for damages, under (f)(1)(vii).

2. Failure to send the required damage list under § 8-203(g)(1) forfeits the right to withhold any part of the deposit for damages, under (g)(2).

3. For an evicted, ejected or abandoned tenant, failure to send the required damage list under the § 8-203(h)(2) procedure forfeits the right to withhold, under (h)(3)(i).

4. Failure to comply with the surety bond requirements under § 8-203(i) forfeits the landlord's right to make a claim against the bond, under (i)(12)(i).

The damages provisions are separate

Several provisions authorise damages of up to three times the amount at issue, depending on the violation. Under (b)(3), an excessive deposit. Under (e)(4), a failure without a reasonable basis to return any part of the deposit plus accrued interest within 45 days. Under (h)(3)(ii), a failure to return under the evicted or abandoned procedure. And within the bond subsection, (i)(3)(iii) for an excessive bond or aggregate, (i)(11)(ii) for an excessive aggregate at renewal after a transfer, and (i)(13) where a surety asserts a claim without a reasonable basis. Maryland's appellate courts have treated the (e)(4) provision as remedial.

And the deposit is not a penalty fund. Under (f)(2), the deposit is not liquidated damages and may not be forfeited for breach of the rental agreement except in the amount the landlord is actually damaged, or the amount of a surcharge authorised under § 7-301(c)(5)(ii) of the Courts Article. Under (f)(3), damages for lost future rents are reduced by any rent received for the premises during the remainder of the term.

Evicted, ejected or abandoned tenants: a different track

Subsection (h) switches off part of the ordinary procedure. The provisions in (e)(1) and (4) and (g)(1) and (2) are inapplicable to a tenant who has been evicted or ejected for breach of a condition or covenant of a lease prior to the termination of the tenancy, or who has abandoned the premises prior to termination.

For such a tenant, the ordinary 45-day return and damage-list provisions are replaced by the procedure in § 8-203(h). The tenant may demand the deposit by first-class mail within 45 days after the eviction, ejection or abandonment, specifying a new address, and the landlord then has 45 days after receiving that notice to send the required damage list with an itemized statement of costs and return the deposit with applicable interest. Failing to send the list forfeits withholding; failing to return the deposit exposes the landlord to threefold damages plus fees.

For a manager, that means two clocks rather than one, and the landlord's clock starts on receipt of the tenant's demand rather than at the eviction. Tracking that alongside the possession file matters, and the possession side of Maryland practice is covered in our guide to the Maryland eviction process and the warrant of restitution.

Common mistakes to avoid

• Using a two-month deposit figure on a lease governed by the amended § 8-203

• Collecting one month's rent from each roommate, when the cap is per dwelling unit regardless of the number of tenants

• Treating advance rent or a pet deposit as outside the cap, when § 8-203(a)(3) defines a deposit as any payment of money including last month's rent paid in advance

• Relying on the two-month exception without all three conditions in § 8-203(b)(2)

• Reading the two-month surety bond ceiling in § 8-203(i)(3) as authority to collect a two-month deposit

• Requiring a tenant to purchase a surety bond, contrary to § 8-203(i)(1)(i)

• Claiming against a bond without sending the tenant a written list and itemized statement at least 10 days beforehand

• Failing to provide the statutory security deposit receipt, which can result in $25 liability under § 8-203.1

• Leaving the receipt out of the written lease, when § 8-203(c)(2) requires it to be included

• Not retaining a copy of the receipt for two years after the end of the tenancy

• Omitting the initial inspection right from the receipt, or ignoring a tenant's certified-mail request made within 15 days of occupancy

• Holding deposits at an out-of-state branch, or in an account that is not devoted exclusively to security deposits and bearing interest

• Missing the 30-day deadline to place a deposit into the account after receiving it

• Paying no interest, or the wrong rate, when the formula is the greater of the one-year Treasury yield curve rate or 1.5%, simple, on deposits of $50 or more held at least six months

• Sending a list of deductions without the supporting documentation identifying the materials or services required by § 8-203(j)(1)

• Using an estimate and never sending the final invoice, or failing to refund the excess within 30 days of completing repairs

• Omitting the written advice of inspection rights at the time the deposit is paid, which forfeits the right to withhold for damages

• Missing the certified-mail reply to a tenant's move-out inspection notice, or inspecting outside the five-day window either side of the moving date

• Treating the deposit as liquidated damages, when § 8-203(f)(2) limits forfeiture to actual damage

• Running the ordinary 45-day clock on an evicted or abandoned tenant, when subsection (h) substitutes its own procedure

• Putting a waiver of any § 8-203 provision in the lease, when subsection (l) prohibits it

• Assuming an over-collection claim goes stale quickly, when § 8-203(b)(4) allows two years after termination

Building a Maryland deposit file that survives

Maryland gives a tenant several treble-damages routes and gives the landlord four separate ways to forfeit a right outright. Almost all of it turns on documents and dates.

Seven records carry it. The lease with the current cap figure and the § 8-203.1 receipt included, since § 8-203(c)(2) requires the receipt to be in the written lease. A retained copy of that receipt, held for two years after the end of the tenancy. Written advice of the inspection rights, dated to the day the deposit was paid, because that is when § 8-203(f)(1)(vi) bites. Any initial inspection request and the resulting written list, where a tenant exercises the 15-day right. The account details showing an in-state branch, exclusive use and the date within 30 days of receipt. The interest calculation and a record that the DHCD calculator was used, since subsection (n) permits reliance. And the written list with supporting documentation, plus, where an estimate was used, the final invoice and any refund within 30 days.

Portfolio-level dashboards and reports can surface tenancies approaching the 45-day mark and estimates still awaiting a final invoice. Because deposits, interest and deductions all have to reconcile to a single figure per unit, rent collection and payment records tied to the tenancy are what make the accounting provable.

Conclusion

The 2024 change is simple to state and easy to under-implement.

• The cap is one month's rent per dwelling unit, regardless of the number of tenants, for tenancies subject to the amended § 8-203. The only route to two months requires all three conditions in § 8-203(b)(2). Over-collection costs up to three times the excess plus fees, claimable for two years after termination.

• But the bond ceiling is still two months. A surety bond, or a bond and deposit combined, may reach two months' rent under § 8-203(i)(3). Two numbers, two provisions, and one very easy mistake.

• The procedure is where files are lost. Thirty days to the account, in a Maryland branch used exclusively for deposits. Forty-five days to return, with interest at the greater of the one-year Treasury rate or 1.5%. A written list with supporting documentation, and a final invoice if you used an estimate. A receipt that must sit in the written lease, describe both the initial and the move-out inspection rights, and be retained for two years. And written advice of inspection rights given at the moment the deposit is paid.

• And nothing can be contracted around. Section 8-203(l) provides that no provision may be waived in any lease.

The operating discipline is short. Fix the template figure. Put the receipt and the inspection-rights advice in the lease itself, and keep a copy for two years. Bank the deposit within 30 days at an in-state branch in an exclusive account. Use the DHCD calculator and keep the record. Send the list with documentation, not a summary. Close out every estimate with a final invoice. And never read the bond number as the deposit number.

Where a system earns its keep

Maryland's forfeiture provisions do not care how good your damage evidence is. They care whether a specific document existed on a specific date.

The failure mode is ordinary. A tenant signs in November 2024 and pays a deposit. The lease packet was updated for the new one-month cap but nobody added the written advice of inspection rights required at the time of payment. Two years later the unit comes back with $3,100 of documented damage, the walkthrough is photographed, the invoices are clean, and the list goes out on day forty. None of it matters, because § 8-203(f)(1)(vii) forfeited the right to withhold for damages at signing.

RIOO can support that workflow directly. Contracts and renewals provides lease templates and centralised document storage, giving managers one place to maintain the current Maryland lease documents and deposit disclosures. Move-in and move-out management provides digital inspection and condition records for both the initial and the move-out inspection. Rent collection and payment records support security deposit tracking, deductions and return records. And dashboards and reports can surface operational deadlines and outstanding work.

In a state with four ways to forfeit, the file you build at signing decides the one you rely on at move-out.

This blog is for informational purposes only and does not constitute legal advice. It states the law as at September 2026 and is drawn from Maryland Code, Real Property § 8-203, with related requirements in § 8-203.1. The one-month cap took effect through the Renters' Rights and Stabilization Act of 2024 on 1 October 2024; leases entered into before that date should be reviewed separately, and the treatment of renewals executed after that date should be confirmed with Maryland counsel. The Department of Housing and Community Development maintains the interest rate list and calculator referred to in § 8-203(m), and a landlord is entitled to rely on them under § 8-203(n). Local jurisdictions including Montgomery County, Prince George's County and Baltimore City may impose additional requirements.

Frequently asked questions

Q1. What is the maximum security deposit in Maryland now?
One month's rent per dwelling unit, regardless of the number of tenants, following the Renters' Rights and Stabilization Act of 2024, which took effect on 1 October 2024. The previous ceiling was two months.

Q2. When can a Maryland landlord still charge two months?
Only where all three conditions in § 8-203(b)(2) are met: the tenant is eligible and has qualified for utility assistance through the Department of Human Services, the lease requires utility payments directly to the landlord, and the parties agree in writing to the amount.

Q3. Does the cap apply per tenant or per unit?
Per dwelling unit, regardless of the number of tenants. Collecting a month's rent from each roommate in a shared house is not what § 8-203(b)(1) permits.

Q4. Is a surety bond also capped at one month?
No. Under § 8-203(i)(3), a bond purchased instead of a deposit may be up to two months' rent, and a bond and deposit together may total up to two months. A landlord may not require a tenant to buy one.

Q5. When must a Maryland security deposit be returned?
Within 45 days after the end of the tenancy, with simple interest at the greater of the one-year U.S. Treasury yield curve rate or 1.5% a year, less any damages rightfully withheld.

Q6. What has to be in the receipt?
The statutory disclosures under § 8-203.1, including the tenant's right to request an initial inspection by certified mail within 15 days of occupancy and the right to be present at the move-out inspection. It must be included in the written lease, a copy must be kept for two years, and failing to provide it carries $25 liability.

Q7. What are the penalties for getting it wrong?
Up to three times the excess charged for an over-collection, up to threefold the withheld amount plus attorney's fees for a return that is late without a reasonable basis, and outright forfeiture of the right to withhold under four separate provisions.

Q8. Can a Maryland lease modify these rules?
No. Section 8-203(l) provides that no provision of the section may be waived in any lease.
