Key Takeaways
Maryland landlords cannot charge more than two months' rent as a security deposit.
Security deposits held longer than 90 days accrue interest at the rate required by Maryland law.
Landlords generally have 45 days after a tenant moves out to return the deposit or provide an itemized statement of deductions.
Normal wear and tear cannot be deducted from a tenant's security deposit, while legitimate damage may be deducted when properly documented.
Mishandling a security deposit can expose landlords to financial penalties, including potentially up to three times the amount wrongfully withheld plus attorney's fees.
A landlord in Canton who charges three months' rent as a security deposit is breaking the law, even if the tenant agrees to it in writing. Maryland security deposit law caps what you can collect, sets a fixed interest rate you owe on that money, and gives you exactly 45 days to return it after a tenant moves out.
Operating outside the lines when it comes to security deposits in Maryland can leave property owners paying the tenant three times the disputed amount, plus their attorney's fees.
The experts at PMI Baltimore created this guide to walk you through what Maryland security deposit law stipulates, so you know exactly where the line is, and can avoid costly disputes if situations arise.
How Much Can You Charge? The Two-Month Cap
Under Maryland Real Property Article § 8-203, a landlord cannot demand a security deposit that is greater than the sum of two months' rent. For example, on a Baltimore rowhome renting at $1,650, close to the citywide average, that caps the deposit at $3,300.
It doesn't matter what a nervous applicant offers to pay to strengthen their odds, or what a landlord thinks the risk justifies. Charging more than two months’ rent as a security deposit is illegal, and a tenant can sue to get it back.
Maryland Security Deposit Interest: What You Owe
Every security deposit held longer than 90 days accrues interest, currently a flat 1.5% annually under state law. That rate has changed over the years, so an owner who's held the same deposit for several years should check what applied to each period, not just today's figure.
On a $3,300 deposit held for one year, that works out to about $49.50 owed to the tenant.
It's a relatively small number for one unit. However Across a ten-unit building, skipped or miscalculated interest is exactly the kind of small error that turns into a costly rent court dispute.
The 45-Day Return Window and Itemized Deductions
Once a tenant moves out and provides a forwarding address, the clock starts. Maryland rental law states that landlords have 45 days to either return the full deposit plus interest, or send an itemized list of damages and deducted costs, along with any remaining balance, by first class mail.
Normal wear and tear doesn't count against a tenant. Scuff marks on the plaster walls of a hundred-year-old Federal Hill rowhome are wear and tear. A hole punched through the same wall is not. Miss the 45-day window, and a landlord can lose the right to keep any of the security deposit, even when real damage exists.

Potential Penalties
Maryland doesn't treat security deposit violations lightly. Withhold a deposit in bad faith, without an itemized list or a legitimate reason, and a court can award the tenant up to three times the amount wrongfully withheld, on top of the deposit itself.
Charge more than two months’ rent up front, and the tenant can recover the excess funds plus damages. These aren't rare, theoretical cases. Rent court in Baltimore City sees them regularly, often from owners who handled the move-out themselves without a written move-in condition record to refer back to.
How PMI Baltimore Handles Security Deposits
Every deposit we collect on an owner's behalf goes into a dedicated trust account, separate from operating funds, exactly as Maryland law requires. Our Protect stage tracks the 45-day return deadline, the interest calculation, and the itemized deduction paperwork so nothing gets missed after a tenant moves out of a Canton condo or a Dundalk duplex.
Move-in and move-out condition reports get documented before any deduction is made, because that's what actually holds up if a tenant challenges a withheld amount in front of a Baltimore City judge. We follow every state law to the letter to protect you as the property owner, including Maryland eviction laws if such a situation ever arises.
We built our compliance process around a simple observation: most deposit disputes come from paperwork gaps, not bad intentions. We're locally owned and independently operated out of Catonsville, and we back our management with seven written guarantees, including a Results Guarantee that means no management fee until you get paid.
Practical Steps to Stay Compliant
Document the property's condition with photos before a tenant moves in, not after a dispute starts. Calculate and disclose deposit interest annually rather than scrambling to figure it out at move-out. Mail the itemized deduction letter within 45 days even if repair invoices aren't fully finalized; a reasonable estimate with a follow-up beats silence every time.
Keep deposits in a separate account, never mixed with rent income or operating cash. Confirm that your Baltimore City rental license and, where it applies, your lead paint risk reduction certificate are current before you touch a tenant's deposit to ensure you are properly protected.
Bottom Line
Maryland security deposit laws give landlords specific rules to follow, from the amount they can collect to how deposits must be held, calculated, documented, and returned. Staying organized throughout the tenancy makes it much easier to remain compliant when a tenant moves out.
For Baltimore-area property owners, following these requirements carefully can help reduce the risk of disputes and unexpected financial penalties. PMI Baltimore can handle the administrative and compliance details associated with security deposits, helping owners protect their investments while staying on top of Maryland's requirements.

Frequently Asked Questions
Can A Maryland Landlord Use A Security Deposit For Unpaid Rent?
A Maryland landlord may be able to apply a security deposit toward unpaid rent when the amount is legitimately owed under the lease and applicable law. However, owners should keep a clear accounting of any amount deducted and distinguish unpaid rent from property damage or other charges. Because security deposit deductions are regulated, landlords should avoid treating the deposit as a general-purpose fund during or after the tenancy. Keeping rent records, the lease, and move-out documentation together can make the accounting process easier and more defensible.
Does Maryland Require A Move-In Inspection For Rental Properties?
A detailed move-in condition record can be extremely useful when managing a Maryland rental, particularly if the owner may later need to distinguish ordinary wear and tear from tenant-caused damage. Photos, written notes, and signed condition reports can establish what the property looked like when possession began. While the article does not establish a universal Maryland inspection requirement, documenting the property's condition is presented as a practical compliance step. Owners should confirm any inspection requirements that apply to their specific property and circumstances.
How Should Landlords Document Security Deposit Deductions?
Landlords should maintain a clear record showing the property's condition, the reason for each deduction, and the amount being withheld. Photographs and move-in and move-out condition reports can help establish whether damage goes beyond normal wear and tear. Owners should also retain invoices, estimates, correspondence, and the required itemized statement. Keeping these records organized is particularly important if a tenant disputes a deduction. For larger portfolios, using a consistent documentation process for every property can reduce administrative errors and make individual move-outs easier to manage.
What Happens If A Landlord Misses Maryland's Security Deposit Deadline?
Missing a statutory deadline can create financial and legal exposure for a Maryland landlord, particularly when the owner has withheld part of a deposit for damages. The article notes that landlords generally have 45 days to return the deposit or provide the required itemized deductions and remaining balance. It also notes that failing to meet applicable requirements can affect the landlord's ability to retain deposit funds. Because the consequences depend on the circumstances, owners dealing with a missed deadline or dispute should consult a qualified Maryland attorney.
Is It Worth Hiring Property Management To Handle Security Deposits?
For owners managing multiple Baltimore-area rentals, professional management may help reduce the administrative burden associated with security deposits. The work can involve tracking deposits, maintaining appropriate records, documenting property condition, calculating applicable interest, preparing deductions, and monitoring return deadlines. Whether management makes financial sense depends on the owner's portfolio size, availability, and comfort handling Maryland's requirements.
