Security Deposit Rules in DC: Caps, Timelines, and What Tenants Can Sue Over
District of Columbia security deposit law appears in D.C. Code 42-3502.17 and sets clear limits on how much you can collect, how fast you must return funds, and what happens when you miss deadlines. The statute applies to most rental housing in DC, including Capitol Hill walkups, NW row houses, and Anacostia investment properties.
One-Month Rent Cap and Interest Requirements
You may collect one month's rent as a security deposit. If a tenant stays twelve months or longer, you must pay interest annually at the passbook savings rate published by the DC Office of the Tenant Advocate. The tenant can apply that interest toward the next month's rent or request a check.
For a Georgetown rent-stabilized unit renting at $1,800 per month, your maximum deposit is $1,800. At 0.25 percent interest, you owe $4.50 after the first year. Tenants often roll that amount into their next payment, but you still must notify them in writing.
30-Day Return Window with Itemized Deductions
You have 30 days from lease termination to return the deposit or provide a written statement itemizing deductions. D.C. Code 42-3502.17 requires specific damage descriptions, repair costs, and unpaid rent amounts. Generic line items such as "wear and tear" or "cleaning" will not survive a challenge.
If you deduct $250 for carpet replacement in a unit that had a six-year-old carpet, the tenant can argue normal wear. Document the carpet's condition with timestamped photos at move-in and move-out. The DC Superior Court Landlord and Tenant Branch hears these disputes and expects contemporaneous records.
What Tenants Can Sue Over
Bad-faith retention of a deposit triggers treble damages plus attorney fees under D.C. Code 42-3502.17. If you withhold $1,000 without justification, a tenant can recover $3,000 plus legal costs. "Bad faith" means you knew the deduction was improper or failed to conduct any reasonable inquiry.
Common triggers include missing the 30-day deadline, failing to itemize, or charging for pre-existing damage. The statute also covers interest disputes. If you skip annual interest payments for three years on a $2,000 deposit, the tenant can sue for the unpaid amount multiplied by three.
Separate Account and Notice Rules
D.C. Code 42-3502.17 requires that you disclose the bank name and account number where the deposit is held. You must provide this information in writing within 30 days of receiving the deposit. While DC law does not mandate a separate interest-bearing account for every tenant, commingling funds without clear records invites disputes.
Many landlords open a dedicated savings account and provide a receipt showing the deposit amount, the bank, and the interest rate. This one-page document satisfies the disclosure rule and creates a clean audit trail if the tenant later claims you never returned funds.
