Seasonal and part-year kitchens: cleaning before reopening

Updated 2026-10-15

Beach stands, ski lodges, summer camps, golf clubhouses, ballpark kitchens: they cook hard for a few months, then sit dark. The exhaust system does not reset while you are closed. Last season’s grease is still in the duct and harder now. Belts have taken a set, birds have found the fan, and the suppression tag may have run out while nobody was looking. This page is the reopening plan: what code says about seasonal kitchens, and what to book in what order before the first service.

Short answer The IFC interval table (Table 606.3.3.1 / 607.3.3.1, depending on edition) and NFPA 96 Table 12.4 list seasonal businesses with low-volume kitchens at a 12-month hood, duct, and fan inspection. Massachusetts lists “day camps, seasonal businesses” as annual and requires a cease-and-desist order where no inspection has happened in the past 12 months. That row is about low volume. A seasonal kitchen that fries or charbroils all summer belongs on the 3- or 6-month row while it is open, so ask your AHJ which row applies. Suppression service stays at every six months under IFC §904, open or closed. The practical plan for most seasonal kitchens is one combined pre-opening window: hood inspection and cleaning first, suppression service right after, then fan, make-up air, grease trap, and health checks before food arrives.

Which interval applies to a seasonal kitchen

Your season looks like	Table row to discuss with your AHJ	Practical cadence
Light cooking: camp dining hall, clubhouse grill, snack bar without fryers	Low-volume: “seasonal businesses” (12 months)	Inspect (and clean if grease is found) once a year, in the pre-opening window
Fryers, flat-top, grill most days while open	“All other cooking operations” (6 months)	Pre-opening plus mid-season if the season runs past about six months, or as the inspector finds grease
Charbroil, wok, or long-hours high volume (stadium, boardwalk)	High-volume (3 months)	Pre-opening plus quarterly while open. See stadium and arena concession cadence
Wood or charcoal	Solid fuel (1 month)	Monthly while operating

Our reading, not code text: the table measures calendar time, not operating days. Months closed do not count as credit. A kitchen inspected last May that reopens next May is at its 12-month mark on reopening day. Confirm with your fire code official. Des Moines’s fire prevention bureau, for example, applies the table as written and does not place its tag on a system with excessive grease until the cleaning is done.

Pre-opening timeline

When	What	Who
4–6 weeks out	Book hood inspection/cleaning and suppression service for back-to-back days. Confirm the health permit renewal and any pre-opening fire inspection your city requires	Owner / GM
2–3 weeks out	Pest control inspection and service (birds and rodents nest in idle fans and ducts). Grease trap or interceptor pump-out if it sat with contents. See combining trap service with hood day	Pest control; liquid waste hauler
1–2 weeks out	Hood, duct, and fan inspection and cleaning. Ask for the report to note anything hardened, nested, or inaccessible	Hood cleaner
Next day	Suppression semiannual service, including fusible links, nozzle caps, cartridge, and releasing unit. The seasonal gap is when caps go brittle and tags expire. See nozzle caps and coverage	Licensed suppression contractor
Same week	Exhaust fan belts and bearings (reinstall belts if they were pulled for the off-season), make-up air filters, burner, and gas check before first use. See fan belts and bearings and make-up air units	HVAC / fan service
2–3 days out	Fan spin test, smoke capture check, suppression panel set, manual pull clear. Flush water lines; confirm hot water; run the dish machine	Facilities + kitchen lead
Opening day	Staff check: filters in, caps on, appliances under their nozzles, Class K extinguisher in place, new service label and suppression tag dated this season	Opening manager

Health departments’ reopening lists overlap here. Natick, Mass.’s pre-opening food establishment checklist includes a pest control inspection and service before opening, a hood ventilation system that is clean and operating, flushing water lines for at least five minutes, and confirming that contracted vendors are available. It is a useful sign-off list for the week before food arrives.

What the off-season does to the exhaust system

Grease left in the duct and fan from last season stiffens and is harder to remove. Do not skip the clean because “we barely cooked in September”
Nests and debris in the rooftop fan or duct termination block airflow and add fuel
Belts take a set or crack; bearings dry out; fans that sat with belts on may squeal or throw a belt on day one
Make-up air units with closed gas valves and switched-off disconnects need a proper restart, not just a thermostat bump
Rubber blow-off caps can go brittle. Ansul’s owner guide says to check that caps are not brittle
Suppression tags expire on the calendar. A six-month tag from last spring has run out by the next spring
Grease trap contents left sitting turn septic. Pump before you open, not after the first backup

Records to keep together

Last season’s hood certificate and report, plus this season’s pre-opening report
Suppression service report and tag dates; fusible link replacement dates
Grease trap pump-out manifest
Pest control service report
Any city pre-opening fire inspection and health permit

See documentation binder. If the kitchen changed hands over the winter, also see taking over a restaurant.

Who it’s for / not for

For: Seasonal restaurants, camps, clubhouses, resort and ski kitchens, ballpark and fairground stands that close for months and reopen on a fixed date
Not for: Year-round low-volume kitchens (see low-volume and church kitchens); brand-new kitchens before first use (see opening a new restaurant); food trucks (see food truck special cases)

Next step

Put your opening date on a calendar and count back six weeks. Book the hood clean and suppression service for back-to-back days in week two, and pest control and grease trap pumping a week before that. Then pull last season’s certificate so the cleaner knows what they left behind.
