Delaware Security Deposit Laws

Delaware's Residential Landlord-Tenant Code (Title 25) heavily regulates how security deposits are collected, held, and returned. Failure to adhere to these strict timelines and limits can result in a landlord paying double the withheld amount in damages to the tenant.

Maximum Deposit Limits

Delaware law places strict caps on security deposits based on the term of the lease and whether the unit is furnished.

Note: Pet deposits cannot be charged for service animals or emotional support animals under fair housing laws. Additionally, Delaware law explicitly forbids landlords from demanding a tenant declaw a cat as a condition of leasing.

Holding the Deposit

Unlike some states, Delaware landlords are required to place residential security deposits in an escrow bank account in a federally-insured banking institution with an office that accepts deposits within the State of Delaware.

The account must be designated as a security deposits account, and the funds cannot be commingled with the landlord's personal or business operating funds. Landlords must disclose the location of the security deposit account to the tenant upon request.

The 20-Day Return Deadline

Delaware has a strict and relatively short window for returning security deposits.

A landlord must return the full security deposit, or provide the tenant with an itemized list of deductions along with any remaining balance, within 20 days after the termination of the rental agreement or the tenant's surrender of the premises, whichever is later.

Penalties for Missing the Deadline

If a landlord fails to provide the itemized list and the balance within the 20-day window, the landlord waives the right to keep any portion of the deposit. Furthermore, if the tenant successfully sues, the court may award the tenant double the amount wrongfully withheld.

Allowable Deductions

A landlord may only deduct from the security deposit for the following reasons:

1. Unpaid Rent: Including late fees, if specified in the lease.
2. Damages Beyond Normal Wear and Tear: Actual costs to repair or replace items damaged by the tenant, their guests, or pets. (Routine painting or carpet cleaning after a long tenancy usually falls under normal wear and tear and cannot be deducted).
3. Breach of Lease Costs: Any actual expenses incurred by the landlord due to the tenant's early termination or breach of the lease.

Best Practices for Delaware Landlords

1. Conduct Inspections: Always perform a documented "move-in" inspection with signed photos, and offer a "move-out" inspection. This is the best defense if a tenant disputes damage deductions.
2. Track the 20 Days Closely: The 20-day clock is unforgiving. Have processes in place to assess damages and send the itemized invoice and check via mail promptly.
3. Keep an Escrow Account: Do not mix security deposits with your regular checking account.
