How Often Does a Commercial Kitchen Hood Need to Be Cleaned in St. Louis? The NFPA 96 Schedule Explained

If you operate a restaurant, hotel kitchen, or commercial foodservice facility in St. Louis, MO, keeping your kitchen exhaust hood clean isn’t just good practice — it’s required by law. The National Fire Protection Association’s NFPA 96 standard sets the minimum cleaning frequency for commercial kitchen hoods, and the St. Louis Fire Department enforces these requirements during inspections.

NFPA 96 Cleaning Frequency Requirements

The required cleaning frequency depends on how heavily your kitchen operates and what types of cooking equipment you use. Here’s the standard NFPA 96 schedule that applies to St. Louis restaurants:

  • Monthly: High-volume cooking operations such as 24-hour restaurants, char-broiling, or wok cooking
  • Quarterly: Moderate-volume cooking including most full-service restaurants in St. Louis
  • Semi-annually: Pizza ovens, pasta cookers, and low-volume operations
  • Annually: Seasonal businesses, churches, and low-volume facilities

Why St. Louis Restaurants Must Stay Compliant

Grease accumulation in your hood and ductwork is the leading cause of commercial kitchen fires. In Missouri, a kitchen fire can result in temporary closure, failed health inspections, and significant liability. The St. Louis Fire Prevention Bureau conducts inspections and can cite facilities that fail to maintain NFPA 96 compliance — with potential fines and mandatory shutdowns.
