DC Security Deposit Laws: Interest and Returns

For an ordinary private DC rental covered by the deposit regulations, security is capped at the first full month’s rent. The owner must hold it in a qualifying interest-bearing escrow account. Within 45 days after the tenancy ends, the owner must return the money and required interest or give the required withholding notice. An itemized statement and remaining balance then follow within 30 days of that notice. These rules appear in 14 DCMR 308–311.

There is now a second process to manage. Effective August 14, 2026, DC added notice, evidence and dispute duties for unpaid amounts claimed after a tenancy ends. A landlord who follows an old deposit checklist may miss those duties. See the Fair Housing Practices Amendment Act of 2026.

The practical goal is to make each dollar explainable: what you collected, where you held it, what interest it earned, and why any amount was retained. Sources were checked October 19, 2026. This is general education; obtain DC legal advice for disputed deductions or unusual coverage questions.

Identify the rules before collecting the deposit

Start with the unit, owner and assistance program. Section 308.8 excludes federal or District agency dwelling units and units with federally subsidized rents from that section. Such housing may have separate deposit requirements. Do not apply an ordinary private-market checklist to a subsidized lease without checking its program rules. Read the official Section 308 text.

A rent-control exemption answers a different question. An owner who properly claims an exemption from annual rent limits should still review deposit law. The DC rent-control exemptions guide explains that separate analysis. A small portfolio or an LLC label does not resolve all landlord obligations.

For voucher housing, keep the lease, assistance contract and program instructions together. Confirm who supplied the deposit and where a refund must go. Our DC Section 8 rent guide explains the different payment streams. A housing-assistance payment is not automatically a deposit contribution.

Also inspect inherited leases. Section 42-3502.17(a) has a special restriction involving certain tenants already in occupancy on July 17, 1985. A buyer should not send a new deposit demand to a longstanding resident simply because the closing file contains no deposit. Review the current deposit statute before changing that arrangement.

Separate security from rent and other charges

Section 308 defines security by its function. Money held to secure lease obligations falls within the definition even if the agreement uses a different name. The limit is the first full month’s rent, and covered security may be charged only once. A renewal or rent increase is not a reason to automatically replenish the original amount. 14 DCMR 308.

For example, suppose the first full month’s rent is $2,500. A $2,000 general deposit plus $700 held for possible damage totals $2,700 of security. Two labels do not turn that total into compliance. Review the payment’s actual purpose before collecting it.

Give the applicant a statement that distinguishes rent, security and any lawful fee. Identify the recipient, due date and refund treatment. The DC tenant-screening guide addresses application fees and pre-lease restrictions, which should be checked before requesting funds.

Avoid treating a move-in fee as an automatic substitute for security. Current DC law prohibits certain charges for services the landlord must provide to maintain a habitable rental. A fee’s amount and disclosure do not establish that it is allowed. Review Section 42-3505.10(b-2) against the actual service.

Build an escrow record that matches the bank

For covered deposits, Section 308.3 requires an interest-bearing escrow account held in trust at an insured financial institution in DC. The account’s purpose is to hold the security. Owners of multiple buildings may use one such account, but the records must still distinguish each tenant’s money. The lease, agreement or receipt must state the payment’s terms. Official escrow and disclosure rules.

Create the account before accepting the first payment. Ask the institution to confirm the account’s structure and provide the statement savings rates needed for your records. A general business checking account with a spreadsheet beside it is not the same arrangement.

Keep a register with these fields:

Record	What to preserve
Tenant and unit	Names on the agreement and exact unit address
Principal	Amount collected, payment date and transaction reference
Terms	Signed agreement and explanation of the payment
Bank	Institution, account identifier and deposit confirmation
Interest	Relevant January and July rates, statements and calculation
Final accounting	Deductions, notices, refund and proof of delivery

Reconcile the register to the bank regularly. A deposit remains a possible repayment obligation. Keep renovation, mortgage and routine operating money in the property’s separate budget. Otherwise a full turnover can create both a repair bill and a cash shortage when the refund becomes due.

Calculate interest from the correct bank records

DC does not publish one universal deposit interest rate for every landlord. Section 311.1 uses at least the statement savings rate prevailing at the holding institution on January 1 and July 1. Those rates apply to the corresponding six-month periods or portions of them. Interest begins when the tenant pays the money. Official Section 311.

Section 311.2 makes interest payable upon termination of a tenancy lasting 12 months or more, subject to lawful deductions. The rule is about tenancy duration. Do not lose the earlier years when a resident signs a renewal. Nor should you assume a short tenancy eliminates the need to establish the proper account.

Use this hypothetical illustration only to understand the arithmetic. Assume a $2,500 deposit and two full half-year periods at annual rates of 0.10% and 0.20%:

Period	Simplified calculation	Interest
First six months	$2,500 × 0.001 × 0.5	$1.25
Second six months	$2,500 × 0.002 × 0.5	$2.50
Total illustrated year	$1.25 + $2.50	$3.75

These are invented rates, not current required figures. Use the actual applicable rates, dates and account earnings for a real tenancy. Preserve the calculation method for partial periods rather than rounding every stay to a year.

Section 311 also addresses earnings above the required statement savings rate and limited use of excess interest for administration. Do not deduct a flat administration charge from the tenant’s principal. Have the calculation reviewed if you use that excess-interest provision.

Keep interest information available throughout the tenancy

Section 308.7 requires year-end posting in the building lobby and rental office identifying where deposits are held and the prevailing rate for each half-year. At tenancy termination, the provider must list the rate for each six-month period during the tenancy. Official posting requirements.

For a property with no conventional lobby or rental office, get guidance on a suitable compliance process. Do not silently omit the duty because the building is a rowhouse. Keep a dated copy of the information supplied and a record of where it was posted.

Put this task beside your other rental administration reminders. The DC BBL and RAD registration guide covers licensing and registration. Those records help identify the responsible owner and manager, but they do not replace the deposit register or bank statements.

If management changes, transfer the historical rates and tenant balances as part of the handover. A new manager needs more than the total balance in the escrow account. Without unit-level records, even a fully funded account can produce incorrect refunds.

Schedule the move-out inspection early

The deposit inspection rule provides a window within three days before or after tenancy termination, excluding Saturdays, Sundays and holidays. If conducting that inspection, the owner must give written notice of its time and date at least ten days beforehand. Conduct it as noticed. 14 DCMR 310.

That combination requires planning before the resident leaves. A reminder created on key-return day may already be too late for the intended inspection. Confirm the termination date, select a permitted inspection date and document delivery of the notice.

Use the original condition report during the inspection. Take clear photographs of the room and any disputed feature. A close-up of a damaged surface is more useful when another image identifies its location and scale.

Record observations before deciding charges. “Bedroom door has a new hole” is an observation. “Tenant owes $500” is a conclusion that requires evidence and a supportable cost. Keep the condition review separate from contractor pricing so the estimate does not determine what you claim happened.

Distinguish damage from ordinary wear

DC law bars withholding security for the replacement value of items damaged by ordinary wear and tear. It also limits what a promise to return the premises in good repair requires. Aging materials and substantial repairs without tenant fault do not become the tenant’s responsibility merely because the lease uses broad wording. Section 42-3502.17(c).

Apply that distinction item by item. Faded paint, an aging fixture and a newly broken cabinet are different conditions. Ask what changed during this tenancy, what caused it, and whether the proposed work corrects damage or improves the property.

Keep purchase dates, prior condition photographs and invoices where available. Charging the complete cost of a new item can be difficult to support when the old item was already worn. Do not invent a mandatory DC depreciation schedule; use facts and obtain advice on the proper measure of a disputed loss.

For cleaning or removal, identify the condition and the actual work. A standard “turnover package” invoice may combine routine owner work with tenant-caused damage. Request a breakdown before assigning any portion to the resident.

Run the deposit-return deadlines separately

Under Section 309.1, within 45 days after termination the owner must either tender the deposit and required interest or provide the specified intent-to-withhold notice. The regulation specifies personal delivery or certified mail to the tenant’s last known address for that notice. Official Section 309.

If withholding, Section 309.2 requires the balance and an itemized statement within 30 days after the notice. That clock follows the notice date. It is not automatically an extra 30 days after day 45.

Task	Deadline or trigger
Full refund, or required withholding notice	Within 45 days after termination
Remaining refund plus itemization after withholding notice	Within 30 days after that notice
Inspection notice, if inspecting under Section 310	At least ten days before inspection
New unpaid-amount notice	Separate 45-day statutory duty discussed below

For a hypothetical October 31 termination, November 20 is within the 45-day window. If the withholding notice is properly given that day, the 30-day follow-up falls on December 20. Do not wait until late December because someone described the process as “75 days.” Verify actual delivery and counting before relying on a deadline.

Add the August 2026 unpaid-amount procedure

The new Section 42-3502.17(e) requires the landlord to request a forwarding mailing or email address when the tenancy terminates. Within 45 days, the landlord must give written notice of alleged unpaid amounts owed under the lease. The notice needs photographs or other supporting documentation, dispute-right information and contact details. Current statutory requirements.

The statute identifies unpaid rent, damage beyond ordinary wear and charges for removing items left at move-out as examples. A disputed claim should show the dates, amount and basis. A total labeled “balance due” does not explain how the owner reached it.

The tenant has 30 calendar days after service to dispute the alleged amounts. The landlord must respond in writing within ten days after receiving the tenant’s information. The landlord must also keep service documentation for at least 60 days before sending the unpaid amount to a debt collector.

The new statute permits personal delivery, email or certified mail for its notice. The existing deposit regulation has its own delivery language. Design a combined procedure that satisfies both where both apply; do not assume an emailed claim alone completes the deposit-return process.

These new duties are not a reason to postpone an otherwise due refund. Track deposit disposition, alleged debt and dispute correspondence separately. The enacted 2026 law changed the claim process without replacing Section 309 with one new deadline.

Work through one supported refund calculation

Assume an ordinary covered tenancy with a $2,500 deposit and $12 of verified interest. The owner has a documented $180 tenant-caused repair and $120 of unpaid rent. Assume both deductions are legally supportable under the agreement and current law.

Item	Amount
Deposit principal	$2,500
Required interest	$12
Supported repair deduction	−$180
Supported unpaid rent	−$120
Refund	$2,212

Attach the rent ledger, repair evidence and calculation to the accounting. Show a zero charge for routine repainting if it is ordinary owner maintenance. Listing an excluded item can explain why the turnover invoice is larger than the tenant’s deduction.

If the tenant produces proof that the $120 rent payment cleared, reconcile it promptly. Correcting that entry raises the refund to $2,332. Preserve the first statement, payment evidence and corrected statement so the change is traceable.

For actual arrears, our DC landlord-tenant process guide addresses the broader legal process. A deposit accounting is not an eviction notice or authorization to collect an unverified debt.

Check deposits before buying or refinancing a rental

A buyer should request deposit balances by unit, collection dates, escrow statements, interest history and pending disputes. Compare the seller’s schedule with each lease. Our DC rental due-diligence guide explains how to reconcile the wider property file.

Ask closing counsel to document how funds and responsibilities transfer. A credit on a settlement statement should be matched to the underlying tenant record. Do not assume the new manager can reconstruct five years of interest from a single number labeled “deposits.”

Keep tenant security outside the cash you describe as available for repairs or loan reserves. A lender’s treatment is program-specific, but money subject to tenant repayment duties should not be casually presented as unrestricted owner cash. Accurate records also help distinguish rent income from one-time receipts.

Use a final review before releasing the accounting

Before sending the final package, confirm the following:

• The termination date and inspection notice are documented.
• The deposit principal matches the lease, bank and tenant register.
• Interest uses the correct historical rates and tenancy duration.
• Each deduction has a lawful basis and supporting evidence.
• Deposit-return and new unpaid-amount notices meet their separate requirements.
• The refund, dispute deadline and response task have named owners.
• Delivery records and payment confirmation are saved together.

Missed deposit duties can have consequences beyond the disputed charge. Section 309 provides liability for money wrongfully withheld and treble damages for bad faith. It distinguishes bad faith from simple negligence or honest error. Do not describe every mistake as an automatic triple award. Deposit remedies.

Use the next lease-up to fix missing records before money changes hands. Pair this process with the DC rent-increase checklist so renewals do not trigger an unsupported deposit top-up. A reliable deposit system should leave the resident and owner able to follow the same calculation.
