TL;DR
In most kitchens the line crew owns anything touching food and the contractor owns the floor. Food contact surfaces, equipment breakdown, cold holding, and product handling stay with staff at close, while floors, drains, and periodic deep work are commonly contracted. Hood and duct cleaning and grease trap service are separate specialist trades entirely, not part of a janitorial scope.
Why kitchens need a written duty split
Kitchens run out of time at close. Somebody is always the last person out, and whatever was ambiguous gets skipped by the person who assumed it belonged to someone else.
A written split fixes it in an afternoon. The same logic applies across every commercial setting, as staff duties versus contracted duties covers, but kitchens punish ambiguity harder than anywhere else because the consequences show up as pests, odor, and failed inspections.
What does the line crew usually own at close?
Line crews typically own everything that touches food or holds it: cutting boards and prep surfaces, slicers and small equipment, flat tops and fryers, cold wells and reach-ins, food storage and dating, sanitizer buckets, and breaking down the line so that surfaces are actually reachable.
This is not a rule handed down from anywhere. It is simply where the knowledge sits. A cook knows how a piece of equipment comes apart, what temperature it must be at before it is touched, and which product is used on it. A general cleaning crew does not, and should not be guessing.
Local food safety requirements govern what your kitchen must do and how it must be documented, and your health authority and your own advisors are the source for that. What follows describes how duties are commonly divided in the field, not what any regulation requires of you.
What usually goes to the cleaning contractor
The contracted side is normally the building rather than the food operation: kitchen floors including under and behind fixed equipment, floor drains and their covers, walls and splash zones, ceiling and vent dusting on a periodic cycle, back-of-house restrooms, the mop sink and closet, dish area floors, and trash and recycling handling out to the enclosure.
Floors are the biggest item and the one most often underestimated. Kitchen floors take grease that gets walked into every seam, and quarry tile with heavy grout lines holds it. A mop alone spreads that film rather than removing it, which is why most working programs include a periodic mechanical deep clean on floors rather than relying on the nightly pass. How hard floor care programs are tiered covers the structure.
Drains deserve a named line in the scope. A neglected floor drain is one of the most common sources of persistent kitchen odor and a frequent pest entry point, and it needs physical scrubbing of the basket and the throat rather than a rinse.
The specialist trades that are not janitorial
Some kitchen work sits outside both the line crew and the general cleaning contract, and treating it as included is a real hazard.
Kitchen exhaust hood and duct cleaning is a specialist trade with its own certification, equipment, and documentation, tied directly to fire risk from grease accumulation in the duct run. Filters at the hood face are often pulled and washed in house; the duct, fan, and roof unit are not. Do not assume a janitorial scope covers any of it -- hire the specialist and keep the service records.
Grease trap and interceptor service is likewise a separate trade with its own disposal requirements. So is pest control, which is a licensed service rather than a cleaning outcome. A clean kitchen makes pest control easier and cheaper; it does not replace it. Refrigeration and equipment servicing sits with the equipment technician.
Naming these exclusions in the scope is as important as naming the inclusions. What a scope of work should list covers how the exclusions column is usually written.
The handoff condition is the part everyone forgets
A cleaning crew cannot clean a floor that is covered in racks, bins, mats, and mop buckets. If the kitchen is not broken down when the crew arrives, the crew mops around the obstacles, and the areas underneath never get touched.
So the split needs a third element beyond who does what: what condition the kitchen is in at the handoff. A reasonable version reads something like this -- floor mats pulled and stood up or moved to the wash area, portable racks and bins moved off the floor, trash out or staged, and the line broken down and surfaces cleared.
A starting point checklist for splitting the work
Adjust this to your kitchen and your local requirements; it is a reader tool, not a service definition.
Line crew, typically: food contact surfaces, equipment breakdown and cleaning, fryers and flat tops, cold holding and product handling, sanitizer buckets, dish area equipment, and clearing the line for the handoff.
Contractor, typically: kitchen and dish floors including under fixed equipment, floor drains, wall and splash zones, back-of-house restrooms, mop sink and closet, periodic high dusting and vents, and waste out to the enclosure.
Specialists, separately: hood and duct cleaning, grease trap service, pest control, and equipment repair.
Gray zones to assign by name: the pass and expo counter, the walk-in floor, the ice machine exterior, the beverage station, and the back door and dumpster pad.

FAQ
What should be on a restaurant closing checklist?
Split it by owner. Line crew: food contact surfaces, equipment breakdown, cold holding, sanitizer buckets, and clearing the line. Contractor or closing team: floors, drains, walls, restrooms, and trash. Name the gray zones such as the pass, the walk-in floor, and the dumpster pad explicitly.
Do commercial cleaners clean restaurant kitchen equipment?
Usually not the food contact equipment. Fryers, flat tops, slicers, and cold wells are typically handled by the line crew, who know how each unit comes apart and what product it takes. Contracted crews normally cover floors, drains, walls, and periodic deep work rather than the cooking line.
Is hood cleaning part of a janitorial contract?
No. Kitchen exhaust hood and duct cleaning is a separate specialist trade with its own certification and documentation because of the fire risk from grease in the duct run. Filters are often washed in house, but the duct, fan, and rooftop unit require the specialist. Keep the service records.
Why does my kitchen still smell after closing?
Check the floor drains first. A drain with a soiled basket or a dry trap is the most common source of persistent kitchen odor, and it needs physical scrubbing rather than a rinse. Grease held in grout lines and an unwashed mop left in a bucket are the next two suspects.
Who cleans under the kitchen line?
Whoever the scope says, and it only happens if the equipment is reachable. Contracted crews commonly cover floors under and behind fixed equipment, but they cannot move a loaded rack or a full bin. The handoff condition needs to require the line be broken down and the floor cleared.
Does a clean kitchen replace pest control?
No. Sanitation reduces food and harborage, which makes pest control far more effective and often cheaper, but pest management is a licensed service in its own right. Treat cleaning and pest control as two programs that support each other rather than as substitutes.
