San Francisco Fire Suppression Systems Compliance Checklist

San Francisco Fire Code Requirements for Hood & Suppression Systems

The San Francisco Fire Code adopts NFPA 96 (Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations) with local amendments that apply to all food service establishments. Every commercial cooking operation with a hood or ventilation system must have an approved automatic fire suppression system, typically a wet chemical suppression system (ANSUL, Captive-Aire, or equivalent) located above the cooking surface. The suppression system must be equipped with both automatic actuation (thermal detection) and manual pull-station activation within 20 feet of the system. San Francisco inspectors verify system installation, permits, and annual inspections during operational reviews.

Key Inspection Items & Common Violations

SFFD inspectors focus on several critical elements: proper clearance distances (minimum 18 inches between hood bottom and cooking surface), intact and tested suppression nozzles, accessible manual pull stations with visible signage, and current inspection tags showing annual certification by a licensed fire protection contractor. Common violations include blocked or obstructed nozzles, expired or missing inspection records (required annually), suppression systems installed without permits, and missing or inadequate hood cleaning between the cooking surface and filters. Systems must be serviced by a California-licensed contractor, and documentation must be posted on or near the equipment for inspector verification.

Maintenance, Documentation & Compliance Checklist

Establish a monthly inspection routine: verify nozzle condition, check manual pull-station accessibility, ensure signage is visible and legible, and inspect hood filters for buildup (which can interfere with suppression system function). Maintain a documented maintenance log including monthly walk-throughs, annual professional inspections, and any service or repairs. Keep the original installation permit and all inspection certificates on file and accessible. San Francisco requires certification every 12 months; schedule service before expiration and retain the inspection tag as proof of compliance. Non-compliance can result in operational citations, fines up to $1,000+ per violation, and potential closure orders if life-safety systems are deficient.
