Houston Fire Suppression Systems Checklist for Food Service

Hood and Ductwork Compliance Requirements

Houston food service operations must install Type I commercial hood systems over all cooking equipment that produces grease or smoke, per the Houston Fire Code (which aligns with the International Fire Code). The hood system includes the hood canopy, ductwork, grease filters, and a damper. All ductwork must be Class 1 galvanized steel, inspected annually for grease buildup, and cleaned by a certified commercial hood cleaning service at least quarterly—or more frequently if equipment is in constant use. The hood must be sealed at the roof penetration and equipped with a functional backdraft damper to prevent backflow during fires.

Suppression System Type and Installation Standards

Houston requires NFPA 17A-compliant wet chemical or dry powder suppression systems for most food service operations. These systems must be installed by a licensed contractor and inspected annually by a certified service provider. The suppression system should activate automatically when heat reaches 135–165°F or via manual pull stations located near exits. System discharge nozzles must be positioned to cover all cooking surfaces and appliances (fryers, griddles, broilers, woks). Documentation of installation, annual certification, and any discharge events must be maintained on-site and available during inspections. Monthly visual checks by staff (pressure gauges, nozzle integrity) are a best practice to catch failures early.

Common Houston Violations and Inspection Checkpoints

Houston inspectors frequently cite grease-laden ductwork, missing or expired suppression system certifications, non-functional pull stations, and inadequate hood clearance from combustible materials. Kitchens must maintain a minimum 3-foot clearance around the hood system and ensure all electrical connections are up to code. Staff training records on how to use suppression systems and when to call 911 are expected. A major violation is operating with a disabled suppression system or failing to service it annually. Keep receipts from hood cleaning and suppression system servicing for at least three years, and ensure your hood system is visibly labeled with the service provider's contact information and last service date.
