Kitchen Exhaust Cleaning Requirements for NYC Restaurants: A Complete Compliance Guide

Operating a restaurant in New York City comes with a complex web of regulatory requirements, and kitchen exhaust system maintenance is one of the most critical — and most frequently cited during inspections. Two sets of rules apply: the national NFPA 96 standard and New York City's own Fire Code. They are not the same, and confusing them is the most common compliance mistake we see.

NFPA 96 (National Standard)

NFPA 96, the Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations, establishes minimum fire safety requirements for the design, installation, operation, inspection, and maintenance of commercial cooking operations.

NFPA 96 sets how often the exhaust system must be inspected for grease buildup, based on the type and volume of cooking. It does not set a fixed cleaning calendar. Cleaning is required whenever an inspection finds the hood, duct, or fan contaminated with grease deposits.

• Solid-fuel cooking operations: inspect monthly
• High-volume operations such as 24-hour cooking, charbroiling, or wok cooking: inspect quarterly
• Moderate-volume operations: inspect semi-annually
• Low-volume operations such as churches, day camps, seasonal businesses, and senior centers: inspect annually

After a cleaning, NFPA 96 requires the service company to leave a written report (including any areas that could not be cleaned) and to label the hood with the company name, the date, and the areas cleaned.

Kitchen Exhaust Cleaning Rules in New York City

The NYC Fire Code goes further than NFPA 96. In the five boroughs, FDNY requires commercial cooking exhaust systems to be inspected and cleaned at least once every three months, and more often if grease builds up faster. Grease filters must be cleaned at least monthly.

The cleaning must be performed by a holder of an FDNY W-64 (or P-64) Certificate of Fitness employed by an FDNY-approved Commercial Cooking Exhaust System Servicing Company, or by a premises-specific F-64 Certificate of Fitness holder for an in-house program. Cleaning records must be kept on the premises for FDNY inspection. The requirements are published on the FDNY W-64 Certificate of Fitness page; ask any vendor to show its current FDNY company approval and its technicians' Certificates of Fitness before you schedule.

Long Island Is Not Under FDNY

FDNY jurisdiction ends at the city line. Restaurants in Nassau and Suffolk counties follow the New York State Uniform Fire Prevention and Building Code, which adopts the NFPA 96 inspection intervals above, enforced by the county or town fire marshal and local fire inspectors. Long Island insurers and landlords frequently write a quarterly or semiannual cleaning schedule into the policy or lease, so check both before assuming the code minimum is enough.

Failure to maintain proper cleaning records can result in violations, fines, and even temporary closure. Insurance companies also require proof of regular kitchen exhaust cleaning, and failure to provide documentation can jeopardize coverage in the event of a fire.

Inspection Is Not the Same as Cleaning

An inspection checks grease loading on the hood, filters, accessible duct, and fan. A cleaning removes grease to bare metal on all accessible surfaces. On a three-month NYC cycle the two usually happen together; on an NFPA 96 semi-annual or annual cycle, the inspection may find the system does not yet need cleaning. Either way, you should receive a dated record of what was inspected and what was cleaned.

After every SaniTech kitchen exhaust cleaning, you receive a dated service report with before/after photos documenting what was cleaned and any inaccessible areas, which you can keep for your fire marshal, health inspector, and insurer, plus a dated hood label. If you are not sure where your system stands, start with a kitchen exhaust system inspection.

Don't wait for an FDNY visit to discover your kitchen exhaust system is out of compliance. Contact SaniTech Services to schedule an inspection or cleaning for your Long Island or New York City kitchen.
