Miami-Dade Commercial Kitchen Ventilation and Grease Management Permits in 2026





Introduction to Commercial Kitchen Ventilation Permits in Miami-Dade County

Commercial kitchen ventilation permits in Miami-Dade County govern the installation, modification, and replacement of exhaust hood systems, grease management equipment, make-up air systems, fire suppression integration, and related infrastructure in restaurants, hotels, hospital kitchens, school cafeterias, and similar commercial food service operations. Every commercial kitchen ventilation installation requires a mechanical permit issued by the local authority having jurisdiction, coordinated with the primary restaurant tenant improvement or new construction building permit. Commercial kitchen ventilation in Miami-Dade County is governed by the Florida Building Code Mechanical 8th Edition (2023), the Florida Fire Prevention Code adopting NFPA 96 commercial kitchen ventilation, and UL listings 710 and 300 for hoods and fire suppression respectively.





Type I and Type II Commercial Hood Categories

Commercial kitchen exhaust hoods divide into two primary categories. Type I hoods, designed to collect and remove grease-laden vapors from cooking operations, are required over equipment producing grease-laden vapors including charbroilers, fryers, ranges, ovens, woks, and any open-flame cooking surface. Type I hoods incorporate grease filters or baffles, grease collection cups, and integrated fire suppression. Type II hoods, designed to collect and remove heat and steam from non-grease-producing equipment, are required over equipment such as dishwashers, steam tables, hot food serving lines, and similar appliances. Type II hoods provide ventilation without grease management or fire suppression requirements.





UL 710 Hood Listing and UL 300 Fire Suppression

Type I commercial hoods installed in Miami-Dade County must be listed under UL 710, which certifies the hood for use in commercial kitchen exhaust applications. The UL 710 listing addresses hood construction, exhaust airflow capacity, grease filtration efficiency, and integration with fire suppression. Fire suppression systems integrated with Type I hoods must be listed under UL 300, which addresses suppression of cooking-oil and grease fires that produce thermal and chemical characteristics distinct from ordinary combustible fires. UL 300 systems use wet-chemical agents that form a vapor-suppressing surface film on hot cooking oils to extinguish the fire and prevent reflash.





Grease Duct Construction Under FBC Mechanical 8th Edition

Grease duct construction from Type I hoods to the exterior building termination is governed by Florida Building Code Mechanical 8th Edition Chapter 5 and NFPA 96. Grease ducts must be welded continuous-construction with no taps or branches except at hood connections, fabricated from at least 16-gauge steel for ducts up to 36 inches and 18-gauge for ducts over 36 inches, sloped continuously toward the hood or grease reservoir for grease drainage, accessible for inspection and cleaning through approved cleanout access doors at code-specified intervals, and clearance-rated to 18 inches from combustible materials unless wrapped with approved grease duct enclosure. Termination of the grease duct above the roof must comply with separation distances from air intakes, property lines, and combustible construction.





Make-Up Air Provisions and Balanced Building Pressure

Commercial kitchen exhaust hoods extract substantial volumes of air from the kitchen, requiring corresponding make-up air to maintain balanced building pressure and prevent negative pressure that would draw outdoor air through doors, windows, and gaps. Make-up air systems include tempered outside air supply with heating and cooling as needed, untempered outside air for moderate climates, and short-circuit make-up at the hood that introduces outside air directly at the hood face. Florida Building Code Mechanical requires that make-up air be tempered when conditions warrant, typically with combustion or refrigeration heating of the supply stream during cooler months. Inadequate make-up air results in poor hood capture, drafts in the dining room, and elevated building energy use.





Grease Interceptor and Grease Trap Sizing

Grease interceptors and grease traps capture grease and food solids from kitchen drain lines before they reach the public sewer, preventing sewer blockage and Sewer Department maintenance issues. Miami-Dade Water and Sewer Department and local municipal Public Works Departments enforce grease interceptor sizing requirements based on kitchen drain fixture units, hood exhaust capacity, or meal volume. Outdoor in-ground grease interceptors typically serve larger restaurants and full-service kitchens, with capacities ranging from 750 to 5,000 gallons. Indoor hydromechanical grease interceptors (grease traps) serve smaller operations or supplement larger systems. Sizing calculations must be documented on the plumbing permit submittal.





Coordination with Department of Business and Professional Regulation

Commercial kitchen ventilation permits coordinate closely with the Department of Business and Professional Regulation Division of Hotels and Restaurants plan review for the food service operation. The DBPR review verifies layout of food preparation, storage, dishwashing, and customer service areas, ventilation including hood placement and capture, plumbing fixtures and grease management, and equipment listing and installation. The DBPR approval letter must accompany the local building permit submittal. Coordinated review between the DBPR approval and the local building permit is essential to avoid conflicts between DBPR-required equipment layout and local code interpretation of clearances, exhaust requirements, and life safety provisions.





Fire Alarm Integration and Hood Suppression Activation

Type I commercial hood fire suppression systems must integrate with the building fire alarm system to provide automatic notification of suppression discharge. Activation of the hood suppression system shuts down the cooking equipment fuel supply (gas valve closure for gas appliances, electrical shutoff for electric appliances), shuts down the exhaust fan to allow the suppression agent to do its work, shuts down the make-up air supply, and signals the building fire alarm to initiate building-wide notification and central station monitoring. The integration requires coordination between the hood manufacturer, the fire alarm contractor, the gas piping contractor, and the local fire marshal.





Required Submittal Documents and Inspections

A complete commercial kitchen ventilation permit submittal in Miami-Dade County typically includes the permit application form, mechanical contractor authorization and current licensure documentation, Notice of Commencement, signed mechanical plan showing hood placement, exhaust duct routing and termination, make-up air system, fire suppression integration, equipment specifications including hood UL 710 listing and suppression UL 300 listing, grease interceptor sizing calculations, DBPR approval letter, and fire alarm coordination documentation. Inspections include rough-in inspection of grease duct construction, hood installation inspection, suppression system installation inspection, fire alarm integration inspection, hood balancing for exhaust and make-up air, and final inspection coordinated with fire marshal sign-off.





Common Causes of Commercial Kitchen Permit Delays

Common causes of commercial kitchen ventilation permit delays in Miami-Dade County include missing DBPR plan review approval, mismatched hood model versus UL 710 listing or suppression system versus UL 300 listing, inadequate grease duct construction documentation or insufficient slope, inadequate make-up air capacity for exhaust airflow, missing grease interceptor sizing calculations or undersized interceptor selection, missing fire alarm integration documentation, and incomplete coordination between mechanical, electrical, plumbing, and fire alarm trades. Permit expediters familiar with NFPA 96 and DBPR requirements can substantially shorten the review cycle.
