New York Commercial Property Laws: Complete Guide for Landlords

New York is one of the more complex and tenant-protective commercial leasing jurisdictions in the United States. Unlike other states where commercial landlord-tenant relationships are governed almost entirely by the lease, New York layers statutory protections—including the prohibition on self-help evictions, the unique Yellowstone injunction remedy, and NYC's Non-Residential Tenant Harassment Law—on top of the contractual relationship.

Key New York Commercial Laws at a Glance

Yellowstone Injunctions

The Yellowstone injunction is a unique New York remedy that gives commercial tenants the right to obtain a court order staying (pausing) a lease termination to allow the tenant time to cure a default.

When a landlord serves a notice of default or notice to cure, the tenant can seek a Yellowstone injunction from Supreme Court. If granted, the court freezes the landlord's ability to terminate the lease while the tenant rectifies the alleged breach—whether it's a missed rent payment, an unauthorized alteration, or any other lease violation.

This is an extraordinarily powerful tenant tool that commercial landlords must account for in their litigation strategy.

NYC Non-Residential Tenant Harassment

In New York City, the Non-Residential Tenant Harassment Law (NYC Admin Code) protects commercial tenants from landlord harassment. Prohibited actions include:

• Using force, threats, or intimidation to force a tenant out.
• Causing repeated, intentional interruptions to essential services (heat, hot water, electricity).
• Blocking access to the leased space.
• Engaging in a course of conduct intended to make a tenant abandon their lease.

Landlords found to have harassed commercial tenants face substantial fines.

Commercial Eviction Process

All commercial evictions in New York require judicial proceedings. Self-help evictions are strictly illegal.

1. Non-Payment: The landlord must first serve a 14-day written demand for rent. If the tenant doesn't pay, the landlord files a non-payment proceeding in Civil Court.
2. Holdover / Lease Violations: The landlord serves a notice to cure (giving the tenant time to fix the violation) or a notice of termination. The tenant may seek a Yellowstone injunction.
3. Court Proceedings: Commercial evictions can take 6 months to over a year in NYC due to court backlogs. Even after a judgment, only a city marshal or sheriff can execute the eviction.

Security Deposits

There is no statutory cap on commercial security deposits in New York. Landlords commonly require deposits equal to 3-6 months' rent, often in the form of a letter of credit. The terms of holding, application, and return are governed entirely by the lease.
