New York gives tenants real leverage on security deposits. The key is a clear, dated demand that cites the deadline the landlord blew, then small claims if they still won't return your money.
Under New York law, a landlord generally must return your security deposit, or give you an itemized statement of any deductions, within 14 days of you moving out. If the landlord misses that window, they can forfeit the right to keep any of the deposit. Confirm the rule applies to your tenancy.
Your move-out date, the deposit amount, the 14-day requirement, and a demand to return the full deposit by a specific date. Note that you'll file in small claims, and that a willful failure can expose the landlord to additional damages under New York law.
Certified mail, return receipt requested. If the deadline passes, file in small claims (up to $10,000 in New York City). Bring your lease, photos, move-out date, and this letter.
