Delaware Security Deposit Demand Letter

Direct answer

In Delaware, the landlord must return the deposit within 20 calendar days. The deadline is measured from this trigger: From the expiration or termination of the rental agreement. The verified state formula is failure to remit deposit or difference with itemized damage list within 20 days: tenant entitled to double the amount wrongfully withheld; also, failure to disclose escrow location within 20 days of written request or failure to deposit in required in-state federally insured institution constitutes forfeiture of the deposit to the tenant, and failure to return full deposit within 20 days of that forfeiture also yields double the deposit under 25 Del. C. § 5514.

Statute says

If the landlord is not entitled to all or any portion of the security deposit, the landlord shall remit the security deposit within 20 days of the expiration or termination of the rental agreement. Within 20 days after the termination or expiration of any rental agreement, the landlord shall provide the tenant with an itemized list of damages to the premises and the estimated costs of repair for each and shall tender payment for the difference between the security deposit and such costs of repair of damage to the premises. Failure to remit the security deposit or the difference between the security deposit and the amount set forth in the list of damages within 20 days from the expiration or termination of the rental agreement shall entitle the tenant to double the amount wrongfully withheld.

25 Del. C. § 5514

What this means

Read the deadline, trigger, and penalty together before sending a letter. Match the dates in your documents to the trigger listed above, then cite 25 Del. C. § 5514 and request the deposit amount supported by your records.

Worked example

Use your actual deposit amount when you write the letter. For context, median rent in Delaware is $1,401 according to U.S. Census Bureau QuickFacts, American Community Survey 2020-2024 5-Year Estimates data as of .

  • New Castle County: $1,448
  • Kent County: $1,354
  • Sussex County: $1,238
  • Wilmington: $1,224

Example demand basis: a deposit equal to the state median rent starts at $1,401 before applying the state formula: failure to remit deposit or difference with itemized damage list within 20 days: tenant entitled to double the amount wrongfully withheld; also, failure to disclose escrow location within 20 days of written request or failure to deposit in required in-state federally insured institution constitutes forfeiture of the deposit to the tenant, and failure to return full deposit within 20 days of that forfeiture also yields double the deposit.
