Unlike residential tenancies—which are capped at one month's rent under the HSTPA—commercial security deposits in New York are entirely unregulated in amount by statute. However, under General Obligations Law § 7-103, cash deposits must be held in trust and not commingled. This fiduciary duty is a mandatory statutory requirement, and any provision of a lease or agreement waiving these protections is absolutely void (GOB § 7-103(3)). Beyond these fiduciary duties and mandatory notification requirements, the amount, form, and return conditions are primarily dictated by the parties' negotiated lease agreement.
No Statutory Limits
New York imposes no cap on the amount a commercial landlord can demand as security. Common practices include:
- 3-6 months' rent: Standard for creditworthy tenants on long-term leases.
- 6-12 months' rent: For startups, restaurants, or businesses with limited credit history.
- Declining deposits: Some leases allow the deposit to reduce annually if the tenant maintains a clean payment history (e.g., from 6 months down to 3 months after year 3).
Forms of Security
Letters of Credit (LOC)
In New York's competitive commercial market, irrevocable standby letters of credit are the gold standard for significant leases.
- The LOC is issued by the tenant's bank and guarantees payment to the landlord upon presentation of specified documents (typically a sight draft and a statement of default).
- Bankruptcy Protection: Unlike cash deposits, a LOC is a direct bank obligation, making it significantly more insulated from a tenant's bankruptcy proceedings.
- The lease must clearly define the conditions for drawing on the LOC and require the tenant to replenish or replace it if drawn.
Good Guy Guarantees
The "Good Guy Guarantee" is a distinctly New York invention. It is a personal guarantee from the tenant's principal that limits their personal liability to the period before they vacate and surrender possession. In exchange for the limited guarantee, the tenant gives the landlord certainty that they won't face a prolonged holdover situation.
Cash Deposits
Cash security deposits are less common for large NYC commercial leases but remain standard for smaller retail and office tenancies. Under GOB § 7-103, landlords must adhere to strict handling requirements:
- Trust Status: The landlord must hold the deposit in trust; it remains the property of the tenant and cannot be commingled with the landlord's personal funds (GOB § 7-103(1)).
- Mandatory Notification: Upon depositing the funds in a banking organization, the landlord must notify the tenant in writing of the name and address of the bank and the amount of the deposit (GOB § 7-103(2)).
- Interest-Bearing Accounts: If the rental property contains six or more family dwelling units (including commercial units in mixed-use buildings), the landlord MUST deposit the security in an interest-bearing account at the prevailing rate (GOB § 7-103(2-a)).
- Administration Fee: Where interest is earned, the landlord is entitled to receive an administration fee equal to 1% per annum upon the principal security money deposited. The balance of the interest belongs to the tenant.
Return of the Deposit
There is no statutory deadline for returning commercial security deposits in New York. The 14-day return deadline under the HSTPA applies only to residential dwellings. The lease must specify the return timeline—typically 30-60 days after the tenant surrenders the premises in the condition required by the make-good clause and all financial obligations are settled. In the absence of a specific lease provision, the deposit must be returned within a "reasonable" time after the tenant vacates.

Frequently Asked Questions
▶What are the New York landlord-tenant laws every property owner should know?
New York is the most tenant-protective state in the US. Its regulatory framework combines the Housing Stability and Tenant Protection Act (HSTPA) of 2019 with the Good Cause Eviction Law of 2024, NYC's rent stabilization system, and extensive local ordinances. Security deposits are capped at one month's rent, late fees at $50 or 5% (whichever is lower), and landlords in NYC must demonstrate 'good cause' to evict or refuse lease renewal.
Read the complete guide▶What is the New York eviction process and how long does it take?
New York's eviction process is lengthy and highly procedural. For non-payment, landlords must serve a 14-day written demand for rent. For holdover evictions, notice depends on tenancy length: 30 days (under 1 year), 60 days (1-2 years), or 90 days (over 2 years). Self-help evictions are strictly illegal. Under the 2024 Good Cause Eviction Law, NYC landlords must demonstrate enumerated legal reasons for eviction, making the process even more demanding.
Read the complete guide▶What is the New York security deposit limit and return deadline?
Under the HSTPA, New York landlords can collect a maximum of one month's rent as a security deposit statewide — this applies to all residential tenancies regardless of whether the unit is rent-stabilized or market-rate. Landlords must return the deposit or provide an itemized statement of deductions within 14 days of the tenant vacating. Failure to comply forfeits the right to retain any portion.
Read the complete guide▶What are the New York rent increase laws and caps for landlords?
New York has multiple layers of rent regulation. NYC rent-stabilized units are governed by the Rent Guidelines Board, which set 3% for one-year and 4.5% for two-year leases in 2025-2026. Under the 2024 Good Cause Eviction Law, increases above 10% or 5% + CPI (whichever is lower) are presumed unreasonable and can be challenged in court. Market-rate units outside NYC remain unregulated unless the municipality opts into Good Cause.
Read the complete guide▶What is the grace period for late rent in New York?
New York mandates a 5-day grace period before any late fee can be assessed. Under the HSTPA, residential late fees are strictly capped at the lesser of $50 or 5% of the monthly rent. Late fees alone cannot be the basis for an eviction proceeding — landlords must pursue a separate non-payment action through Housing Court if rent remains unpaid after the 14-day demand notice.
Read the complete guide▶What disclosures must New York landlords provide to tenants?
New York requires extensive pre-lease disclosures including lead-based paint (plus NYC Local Law 1 for pre-1960 buildings), bed bug infestation history (NYC), flood risk and prior flood damage (statewide since 2023), mold history and remediation (NYC), Good Cause Eviction coverage status, window guard requirements for units with children under 11 (NYC), and smoke and carbon monoxide detector compliance.
Read the complete guide▶What is Good Cause Eviction in New York and how does it affect landlords?
Effective April 20, 2024, the Good Cause Eviction Law transformed the landscape for market-rate apartments in NYC and opt-in municipalities. Landlords must now demonstrate enumerated legal reasons (non-payment, nuisance, illegal use, refusal of access) to evict or refuse lease renewal. The law also caps rent increases — increases above 10% or 5% + CPI are presumed unreasonable and tenants can challenge them in court.
Read the complete guide▶What are New York landlord maintenance obligations and habitability standards?
New York enforces the implied warranty of habitability, requiring landlords to maintain properties in livable condition. This includes working plumbing, heating (minimum 68°F during the day, 62°F at night from October to May), electrical systems, pest control, and structural integrity. NYC has additional requirements including window guards, lead paint abatement, mold remediation, and elevator maintenance. Tenants may withhold rent if habitability violations remain unaddressed.
