Security deposit rules in Delaware
The two numbers that matter most: how much can be collected, and how fast it must come back.
Deposit limit
1 month's rent (on year-long leases)
Return deadline
20 days
If you're a tenant:document the unit on day one — photos, video, and a signed move-in checklist. Deposit disputes are almost always evidence disputes, and the side with time-stamped photos usually wins. When you move out, provide a forwarding address in writing; in most states the return clock doesn't start without it.
If you're a landlord: Treat the deadline as hard. Return the deposit within 20 days with an itemized statement for any deductions, and only deduct for unpaid rent or damage beyond normal wear and tear. Milo, our property management expert, covers the full move-out process — inspections, itemization, and the disputes worth avoiding.
Common questions
How much can a landlord charge for a security deposit in Delaware?
Delaware's limit is 1 month's rent (on year-long leases). Charging more than the cap is a statutory violation, so both sides should check the math before signing.
How long does a Delaware landlord have to return the deposit?
Delaware requires the deposit back within 20 days of move-out, typically with an itemized list of any deductions. Missing the deadline can expose the landlord to penalties — in many states, multiples of the amount wrongfully withheld.
What can a landlord deduct from a deposit in Delaware?
Like most states, Delaware allows deductions for unpaid rent and damage beyond normal wear and tear — but not for ordinary aging like faded paint, worn carpet paths, or small nail holes. Documentation (a move-in checklist and photos from both ends of the tenancy) decides most disputes.
