Re: Demand for Return of Security Deposit — $2,400.00
Former Address: 527 Amsterdam Avenue, Apt 6A, New York, NY 10024

Dear Mr. Greenfield,

I am writing to formally demand the return of my security deposit in the amount of $2,400.00 for the above-referenced apartment, which I vacated on December 15, 2025. As of the date of this letter, 31 days have passed since my move-out, and I have not received either my deposit or an itemized statement of any deductions.

Timeline of Events:

On August 1, 2023, I entered into a one-year residential lease for Apartment 6A at 527 Amsterdam Avenue, New York, NY 10024. At that time, I paid a security deposit of $2,400.00, equal to one month's rent. The lease was subsequently renewed for an additional term. I provided written notice of non-renewal on October 15, 2025, and vacated the premises on December 15, 2025, returning all keys to your office on the same date.

Prior to vacating, I thoroughly cleaned the apartment, filled all nail holes, and left the unit in substantially the same condition as when I took possession, ordinary wear and tear excepted. I have dated photographs documenting the apartment's condition on both move-in and move-out dates.

Legal Basis:

Under New York General Obligations Law § 7-108, a landlord must return a tenant's security deposit, together with an itemized statement of any deductions, within fourteen (14) days after the tenant vacates. You are now 17 days past this statutory deadline.

Furthermore, under GOL § 7-108(1-a), deposits must be held in a separate interest-bearing account at a New York banking institution, and tenants are entitled to receive annual interest earned on the deposit. I have received no such accounting during my tenancy.

New York courts have consistently held that a landlord's failure to return a security deposit within the statutory period, or to provide an itemized statement of deductions, constitutes a waiver of the right to retain any portion of the deposit. See Pisgah Holdings LLC v. Ferreira, 2018 NY Slip Op 28390 (Civ. Ct. 2018). In cases of willful violation, courts may award the tenant up to twice the amount of the deposit in damages.

Demand:

I hereby demand the return of $2,400.00, representing the full amount of my security deposit plus any accrued interest, within fourteen (14) days of your receipt of this letter. Payment should be made by certified check payable to Sarah M. Chen and sent to the address above.

Consequences of Non-Compliance:

If I do not receive payment within the stated deadline, I will file a claim in the Civil Court of the City of New York, Small Claims Part, seeking return of the full deposit, statutory penalties of up to twice the deposit amount, court filing fees, and any additional damages permitted by law. I will also file a complaint with the New York State Attorney General's Office and the NYC Department of Housing Preservation and Development.

I trust this matter can be resolved without the need for litigation. Please contact me at the number or email above if you wish to discuss.

Sincerely,

[Signature]

Sarah M. Chen

Enclosures:
— Copy of signed lease agreement
— Move-out photographs (dated 12/15/2025)
— Receipt for key return

📝 Why this works: This letter succeeds because it (1) establishes a clear timeline, (2) cites the specific statute and deadline, (3) references case law supporting penalty damages, (4) gives a firm but reasonable response deadline, and (5) documents that photographic evidence exists. The professional tone signals legal sophistication without being hostile.

Breakdown: What Makes This Letter Effective

1. Precise Documentation

The letter establishes an irrefutable timeline — lease start date, deposit amount, notice date, move-out date, and the exact number of days past the statutory deadline. This level of precision signals to the landlord that the tenant is organized and prepared for court.

2. State-Specific Legal Citations

Rather than vaguely threatening legal action, the letter cites NY GOL § 7-108 by section and subsection. It also references case law (Pisgah Holdings v. Ferreira) establishing that failure to return a deposit within 14 days constitutes a waiver. This demonstrates legal knowledge and makes the threat credible.

3. Clear Damages Calculation

The letter specifies the exact amount demanded ($2,400.00) and mentions the potential for double damages. The landlord can immediately understand their financial exposure: pay $2,400 now or risk $4,800+ in court.

4. Multiple Escalation Paths

The letter doesn't just threaten small claims court — it mentions the Attorney General's Office and HPD. This multi-pronged approach increases the perceived cost of non-compliance.

5. Professional Tone

Despite firm language, the letter remains professional and offers an opening for discussion. Courts view favorably parties who attempted reasonable resolution before filing suit.
