NFPA 96, the standard governing commercial cooking ventilation and fire protection, and the Florida Fire Prevention Code that adopts it, require kitchen hood suppression for equipment that produces grease-laden vapors during the cooking process. This includes fryers, griddles, char-broilers, ranges, and similar equipment. It is the presence of this type of cooking equipment, not the restaurant’s concept, seating capacity, or hours of operation, that determines whether suppression is required.
This means two businesses that look completely different on the surface, a full-service sit-down restaurant and a small quick-service counter, both need suppression if they are both operating a fryer, even if one seats two hundred people and the other has no seating at all.
The key distinction throughout all of these examples is the equipment itself, specifically whether it produces grease-laden cooking vapor, not the marketing concept built around the menu.
A concept that opens without suppression because it initially used only cold prep or non-grease-producing equipment does not stay exempt forever if the menu expands. Adding a fryer or a flat-top griddle later, even informally or as a seasonal addition, immediately triggers the requirement for hood suppression on that new equipment, and operating it without suppression in place is a code violation regardless of how the rest of the kitchen was originally permitted.
This is a situation we see fairly regularly with growing concepts. A juice bar adds a panini press, or a coffee shop starts offering a simple hot breakfast sandwich menu using a small griddle, without realizing that equipment addition changes their fire protection obligations. It is worth checking with a fire protection contractor before adding any cooking equipment to a previously suppression-free kitchen, not after the fact.
Your local AHJ, generally the fire marshal’s office reviewing your permit application, makes the final determination based on your actual equipment schedule submitted during the permitting process. A fire protection contractor experienced in commercial kitchen permitting can review your proposed equipment list early in the planning process and flag whether suppression will be required, which is far more useful than finding out during a permit review after you’ve already ordered equipment or signed a lease based on assumptions.
Ghost kitchens and shared commercial kitchen facilities present their own version of this question, since multiple operators may be using the same hood and suppression system for different menus and equipment. In these arrangements, the suppression system has to be designed and maintained to cover the full range of equipment actually used by every tenant operating under that hood, and responsibility for keeping the system compliant is a question worth resolving clearly in any shared kitchen agreement before equipment changes hands between operators.
If the food truck uses equipment that produces grease-laden vapor, such as a fryer or griddle, it needs an appropriately sized suppression system, following the same underlying NFPA 96 and NFPA 17A principles as a fixed commercial kitchen, though the specific equipment and mounting differs for a mobile unit.
Equipment size does not exempt a business from the suppression requirement. If the equipment produces grease-laden vapor, it needs to be protected by an appropriately designed suppression system regardless of its physical size.
Yes, but it typically requires closing the affected cooking area temporarily during installation, and operating that equipment without required suppression in the meantime is a code violation that puts your permit and potentially your ability to keep operating at risk.
Generally, the suppression system belongs to and covers the physical kitchen space and its hood, not each individual operator using that space. What matters is that the system is properly designed and maintained to cover all the equipment actually used in that kitchen, whoever is using it.
As early as possible, ideally before finalizing your equipment list and kitchen layout. Confirming suppression requirements upfront avoids costly changes to your build-out plans or permitting delays discovered late in the process.
