Maryland rule applied to your numbers
Maximum deposit
$2,000
Up to 1 month’s rent under Maryland law. The Renters' Rights and Stabilization Act of 2024 lowered the cap from two months' rent to one month's rent for leases signed on or after October 1, 2024. The one-month limit applies per dwelling unit regardless of the number of tenants and includes any pet deposit. A landlord may charge up to two months' rent only in a narrow case: the tenant qualifies for utility assistance through the Department of Human Services, the lease requires the tenant to pay utilities directly to the landlord, and both sides agree to the amount in writing.
Return deadline
45 days
45 days after the end of the tenancy. Enter your move-out date for the exact deadline.
These are the Maryland figures applied to what you entered: a plain summary of the rule and the dates, not a determination that anyone did or did not comply.
If a deposit is wrongly kept
A landlord who withholds a deposit in bad faith, or who fails to send the itemized list within 45 days, can be liable for up to three times the amount wrongfully withheld plus reasonable attorney's fees. Charging a deposit above the legal cap also exposes the landlord to up to three times the excess plus attorney's fees. A tenant may sue during the tenancy or within 2 years after it ends.
Interest on the deposit
Interest is required on any deposit of $50 or more that the landlord has held for at least 6 months. It accrues as simple interest at monthly intervals from the day the tenant hands over the deposit. Each year the rate is the greater of the 1-year U.S. Treasury yield as of the first business day of that year, or 1.5% per year. Maryland publishes an official Rental Security Deposit Calculator so the exact amount can be worked out.
Local ordinances
Montgomery County enforces the state rules through its Office of Landlord-Tenant Affairs, where tenants can file complaints, and treats a failure to meet the return requirements as forfeiting the landlord's right to withhold any part of the deposit. Baltimore City also follows the state statute. Check your county for extra local filing options before going to District Court.

How Maryland security deposits work
Maryland is one of the states that makes landlords pay interest on your security deposit, so your money is not supposed to just sit idle. Interest is owed on any deposit of $50 or more that the landlord has held for at least 6 months, at the greater of the 1-year U.S. Treasury rate set each January or 1.5% a year, and the state runs a free official calculator to work out the amount. The size of the deposit itself also dropped recently: for leases signed on or after October 1, 2024, a landlord can ask for no more than one month's rent, down from the old two-month cap. After you move out, the landlord has 45 days to return the deposit with interest or mail you an itemized list of any damages being charged. If the landlord keeps your money in bad faith or misses that 45-day deadline, you can recover up to three times the amount wrongfully withheld plus your attorney's fees.
