The 45-Day Rule: What It Actually Requires
Maryland law gives landlords 45 days after the tenancy ends to return the security deposit. That 45-day window covers three things that must happen together:
- The deposit itself (minus any lawful deductions) must be returned
- Any required interest must be included
- A written, itemized statement of any deductions must be provided — with documentation
All three must be sent to the tenant’s last known address within 45 days. Sending the check without the itemization, or sending the itemization without the check, does not satisfy the requirement.
The clock starts when the tenancy ends — not when the tenant formally notifies you, not when keys are returned, and not when you complete your inspection. The end of the tenancy is the trigger.
Keep proof of mailing. Certified mail is not legally required by the statute, but it creates documentation of the send date and delivery that is invaluable if a dispute goes to court.
What You Can and Cannot Deduct
This is where most landlord deposit disputes originate. Maryland law allows deductions for specific categories of loss — and prohibits others explicitly.
Allowable Deductions
Unpaid rent. Any rent that remains unpaid at the end of the tenancy may be deducted from the deposit.
Damage beyond normal wear and tear. Physical damage to the unit, fixtures, appliances, or common areas that exceeds what ordinary use would cause over the tenancy period. Examples: large holes in walls, broken doors or windows, stained or burned carpet, damage to appliances from misuse.
Excessive cleaning costs. If the unit requires cleaning beyond what would be expected from normal use — not baseline cleaning, but cleaning that a reasonable tenant should have handled before vacating.
Lease violation costs. Documented costs directly resulting from a tenant’s breach of the lease terms.
Not Allowable Deductions
Normal wear and tear. Maryland law explicitly prohibits deducting for conditions that result from ordinary use over time. This includes:
- Minor wall scuffs, small nail holes, or faded paint
- Carpet worn from foot traffic (not stained or damaged)
- Loose door handles or hinges from regular use
- Light fixture wear
Routine repainting. Repainting a unit between tenancies is a standard landlord cost, not a tenant obligation — unless the tenant caused damage that required it (graffiti, large holes, smoke staining).
Carpet replacement due to age. If carpet has reached the end of its useful life, the tenant is not responsible for replacement cost. Landlords can only charge for damage that shortened the carpet’s useful life beyond normal depreciation.
Property upgrades. You cannot use the deposit to fund improvements to the unit — only to repair actual damage.
Documentation Standard
Every deduction must be supported by actual documentation: invoices, receipts, repair estimates. You cannot deduct based on your own estimate of what a repair might cost. If you don’t have a receipt or invoice, you don’t have a deductible item.
Allowable vs. Not Allowable: Quick Reference
| Allowable | Not Allowable |
|---|---|
| Unpaid rent | Normal wear and tear |
| Broken fixtures from misuse | Minor wall scuffs or nail holes |
| Large holes in walls | Routine repainting |
| Stained or burned carpet | Carpet worn from foot traffic |
| Damage to appliances from misuse | Age-related appliance wear |
| Excessive cleaning | Standard end-of-tenancy cleaning |
| Lease violation costs | Property upgrades or improvements |
Interest Requirements
Maryland requires landlords to pay interest on security deposits that are held for at least six months.
Interest rate: The greater of 1.5% per year or the equivalent of the one-year U.S. Treasury yield curve rate, calculated as simple interest.
Accrual: Interest begins accruing from the date the deposit is received.
Minimum holding period: If the tenancy lasts less than six months, no interest is required.
Payment: Interest must be included with the returned deposit within the 45-day window. It is not a separate obligation — it’s part of the return.
Maryland’s Department of Housing and Community Development provides an interest rate reference that landlords can use to calculate the correct amount. Using the wrong rate — or omitting interest entirely on a qualifying tenancy — is a statutory violation.
Move-Out Inspection: Rights and Risks
Maryland law gives tenants the right to request a move-out inspection and to be present during it. Here’s how the process works:
Tenant request window: The tenant must request the inspection within 15 days before the end of the tenancy.
Landlord obligation: Once a valid request is made, the landlord must provide reasonable notice of the inspection time and allow the tenant to attend.
What the inspection affects: A properly conducted move-out inspection — with the tenant present — creates a shared record of the unit’s condition. This documentation is your strongest evidence if a deduction dispute goes to court.
Risk of skipping: If you fail to honor a tenant’s valid inspection request, your ability to defend deductions may be compromised. A tenant can argue that you prevented them from documenting the condition of the unit.
Best practice regardless of inspection: Take time-stamped photos and video of the entire unit at move-out. Document every condition that you intend to deduct for. The more thorough your move-out documentation, the stronger your position in any dispute.
What Happens If You Return It Late
This is the section that matters most for risk management.
If a Maryland landlord fails to return the deposit and itemized statement within 45 days, the tenant may pursue all of the following:
Triple damages. The tenant can sue for up to three times the amount of the deposit wrongfully withheld — not three times the deduction, three times the total deposit.
Attorney fees. The court may award the tenant’s reasonable attorney fees in addition to damages.
Forfeiture of deductions. A landlord who misses the 45-day deadline loses the right to retain any portion of the deposit — including deductions that would otherwise have been valid.
Example scenario:
A tenant vacates a $2,500/month rental on July 1. The landlord has legitimate repair claims totaling $800 and intends to return $1,700 of the $2,500 deposit. The landlord sends the check and itemization on August 20 — 50 days after move-out, 5 days late.
Result: The landlord is in violation. The tenant can sue for up to $7,500 in triple damages plus attorney fees — on a $2,500 deposit — even though $800 of the withholding was legally valid. The 5-day delay converted a legitimate deduction into maximum legal exposure.
Common mistakes that cause late returns:
- Waiting to collect all repair invoices before sending anything
- Sending the check and itemization separately, on different days
- Miscounting the 45-day window from the wrong start date
- Mailing to the wrong address and having to resend
- Not accounting for weekends when the deadline falls near the end of the month
The safest practice: target Day 30 as your internal deadline, not Day 45. The buffer protects you from administrative errors.
The New 1-Month Cap (October 2024)
Maryland changed the security deposit cap effective October 1, 2024. For most residential leases signed on or after that date, the maximum deposit is 1 month’s rent.
The prior rule allowed up to 2 months’ rent in most cases. Many online resources — including competitor guides — still publish the old 2-month figure. If you signed a new lease after October 1, 2024 and collected more than one month’s rent as a deposit, you are not in compliance with current law.
What this means practically:
- Existing leases signed before October 1, 2024 are generally governed by the rules in effect at the time of signing
- New leases and renewals signed after October 1, 2024 are subject to the 1-month cap
- Pet deposits are treated as part of the total security deposit for purposes of the cap — you cannot collect 1 month’s rent as a “security deposit” and then an additional pet deposit on top of it for new leases
Anne Arundel County: Local Context
Anne Arundel County operates under Maryland state law for security deposit rules — the 45-day deadline, interest requirements, deduction standards, and penalty exposure all apply countywide under the state statute.
County-specific factors that affect deposit administration:
Rental licensing. If your property is subject to Anne Arundel County’s Multiple Dwelling License requirement, your licensing status may affect your ability to pursue claims in District Court. Confirm your licensing is current before a tenancy ends.
District Court of Maryland — Anne Arundel County. Deposit disputes are filed in District Court as small claims or civil actions depending on the amount. The Anne Arundel County District Court is located at 251 Rowe Boulevard, Annapolis. For deposits under $5,000, the small claims process is typically used.

Baltimore City: Additional Considerations
Baltimore City landlords are subject to the same state deposit law, with a few local procedural notes:
- Baltimore City has an active tenant advocacy infrastructure — deposit disputes are filed more frequently and tenants are more likely to have legal representation
- The 10-day late fee grace period (vs. 5 days statewide) also applies in Baltimore City for other aspects of the landlord-tenant relationship
- Local housing court familiarity with deposit cases is high — procedural errors are more likely to be caught and penalized
How Professional Management Reduces Deposit Risk
Security deposit mishandling is the single most common source of legal exposure for self-managing Maryland landlords — and it’s almost entirely avoidable with the right systems.
Professional property management companies use standardized deposit workflows: documented move-in and move-out inspections, tracked 45-day deadlines, itemization templates with invoice requirements, and certified mailing procedures. These systems exist specifically because the penalty for getting it wrong is severe.
For landlords managing their own properties, the practical question is whether your current process would hold up if a tenant filed in District Court today. If the answer is uncertain — if you don’t have documented move-in conditions, if you’re not tracking the 45-day window explicitly, or if your itemization process relies on estimates rather than invoices — that’s the exposure.
