In a ghost kitchen or multi-operator commissary, the hood suppression system typically covers multiple cooking stations under a shared or segmented exhaust hood. Each suppression zone must protect the cooking equipment in its coverage area, and the combined system serving multiple operators must be inspected and documented as a complete system, not as individual operator subscriptions. The semi-annual inspection must cover the entire installed system, regardless of how many operators share it.
This is the architecture problem that produces most ghost kitchen suppression compliance gaps. An operator paying for semi-annual suppression service from their own vendor may receive a service report covering only the cylinder and nozzles associated with their station. The shared duct, the rooftop fan, and nozzles covering adjacent stations may be undocumented. A fire marshal inspecting the facility sees the full system and expects documentation of the whole installation, not a collection of partial operator records.
In a ghost kitchen or commissary, the facility operator or landlord is typically responsible for the shared hood and suppression infrastructure, while individual operators are responsible for their own cooking equipment and the suppression coverage directly associated with it. The division depends on the facility’s lease and operating agreement, but the shared infrastructure, shared duct, rooftop fan, and any nozzles covering multiple stations, requires a named responsible party whose service documentation covers the full system.
The cleaner compliance model is a facility-level suppression service program that covers the entire installed system, with the facility operator holding the service documentation and making it available to any individual operator who needs it for an event, permit, or licensing inspection. This eliminates the gap where multiple partial operator records exist but no single record documents the complete system.
A ghost kitchen facility’s hood cleaning schedule must reflect the aggregate cooking volume running through the shared exhaust system, not the volume of any individual operator. When multiple concepts share a single exhaust path, the combined grease output of all operators using that duct accumulates in the shared ductwork and rooftop fan. A shared duct serving several high-volume operators may need quarterly cleaning even if each individual operator’s volume would suggest a less frequent interval.
This is the math that ghost kitchen operators and facility managers most often miss. A shared exhaust system that routes through a common duct is accumulating grease from every station that uses it. The cleaning interval has to account for the combined load, and a cleaning that covers only the individual hood above one station does not address the shared duct accumulation below it. A facility-level cleaning program that treats the full exhaust path as a single system is the correct structure.
| Shared System Component | Responsible Party | Documentation Requirement |
|---|---|---|
| Individual cooking station nozzles | Operator or facility (confirm by agreement) | Part of semi-annual suppression service report |
| Shared exhaust duct | Facility operator | Full duct cleaning documented at each service |
| Rooftop exhaust fan | Facility operator | Fan housing cleaning and condition documented |
| Agent cylinder(s) | Per station assignment (confirm by agreement) | Weight / pressure check at each semi-annual service |
| Full system service report | Facility operator holds master copy | Available for any operator’s inspection, permit, or event need |
A Doral or Kendall ghost kitchen facility should establish a facility-level suppression service program with a single licensed company responsible for servicing and documenting the entire installed system, covering every operator’s station and all shared infrastructure, and produce one unified service report that accounts for the full system. Cleaning should be scheduled based on the aggregate cooking volume through the shared duct, not on individual operator volume.
Operators in the facility then receive a copy of the facility service report for their own compliance file rather than commissioning redundant partial service visits. This structure is both more efficient and more compliant than the alternative, where multiple operators each engage separate vendors and the shared infrastructure remains undocumented in the seams between them. For a ghost kitchen or commissary looking for a fire protection company near me to structure this program, the key question is whether the company has experience servicing multi-operator shared hood systems rather than single-tenant restaurant kitchens.
In a ghost kitchen, multiple operator service records do not add up to a compliant shared system. A fire marshal inspecting the facility looks at the full installation, and gaps in the shared duct and rooftop documentation are visible in a way that no individual operator’s clean service report covers. One company, one facility-level service program, one unified report covering the entire installed system is the structure that actually works for a shared kitchen.
Yes. Any ghost kitchen or commissary operating cooking equipment that produces grease-laden vapors needs a listed fire suppression system under the exhaust hood, semi-annual suppression inspection, and hood cleaning at the interval appropriate for the cooking volume through the shared system. The requirements are the same as a standalone restaurant kitchen.
The facility operator or landlord is typically responsible for shared hood and suppression infrastructure, while individual operators are responsible for their own cooking stations. The division should be defined in the lease or operating agreement. The shared duct, rooftop fan, and any nozzles covering multiple stations need a named responsible party whose documentation covers the full shared system.
A ghost kitchen’s cleaning interval must reflect the aggregate cooking volume through the shared exhaust system, not just the volume of any one operator. Multiple high-volume operators sharing a single duct can push the combined cleaning requirement into the quarterly tier even if individual operator volumes might suggest less frequent service.
Individual operators can maintain service for their own stations, but a facility with shared exhaust infrastructure also needs a facility-level service that documents the complete shared system. Partial operator records do not add up to full system documentation, and a fire marshal inspecting the facility expects to see the whole installation covered in the service records.
Ghost kitchens and commissaries share hood infrastructure between multiple operators, which creates compliance gaps that individual operator service programs miss.
