Inspect and document the unit
As soon as the tenant moves out, photograph every room and compare it against the move-in condition. In New Jersey, deductions generally must reflect actual damage beyond normal wear and tear.
- 2
Itemize every deduction in writing
List each deduction with a dollar amount. New Jersey — like nearly every state — can bar a landlord from keeping any of the deposit if deductions aren't itemized in a written statement.
- 3
Add any interest owed

Return the balance within 30 days
Send the remaining balance and the itemized statement to the tenant's forwarding address within 30 days of move-out. Missing this deadline is the single most common way landlords lose a deposit dispute.
