WHERE THIS CUISINE QUIETLY COSTS YOU MONEY
Fried Chicken / Wings / Quick-Service Fry-specific conversion gotchas
01 · Fryer-bank grease interceptor sizing
A 4-vat fryer line at 50 lbs/vat cycles about 200 lbs of oil, which goes to a used-oil container, not the drain — but basket, filter-pan and floor washdown still send grease to the interceptor. Its size comes from the fixtures that drain to it, by the method in your city's plumbing code (UPC: drainage fixture units; IPC: flow rate; local amendments vary), so confirm the AHJ's sizing for the existing interceptor before you sign the lease.
02 · Pressure-fryer gas + ventilation
A gas pressure fryer such as the Henny Penny PFG-600 is rated 80,000 BTU and vents steam during the cook cycle. The IMC treats pressure fryers as medium-duty appliances under a Type I hood (IMC §202, §507.2); make sure the hood's fire-suppression system covers the fryer (IMC §509) and have the gas piping checked for the added load rather than assuming a tee off the existing line will do.
03 · Breading station + flour dust
Hand-breading stations put flour in the air. Keep the breading table away from walk-in evaporator coils and the make-up-air path, and decide with your mechanical designer whether local exhaust is worth it — the IMC's Type II hood rule (§507.3) is for appliances that give off heat and moisture, not for flour dust.
04 · Used-oil tank logistics
A high-volume wing/chicken op burns 30–50 gallons of oil per week. Plan an exterior 200–400 gallon used-oil tank with weekly haul-out, accessible to the renderer truck without crossing the dining patio. Many landlords prohibit oil tanks at the front; the lease must specifically permit a back-of-house pad.
05 · Drive-thru lane + stack-up
A quick-service fryer concept lives on drive-thru, and the city's zoning code sets the minimum queue (stacking) length — it varies; Phoenix, for example, sets a minimum queuing length per pick-up window in its zoning code. Inherited strip-mall lots may not fit it, so confirm queue length, exit-lane geometry, and any traffic study BEFORE design, not at permit submission.
Five immediate stop signals
These cancel any deal regardless of cuisine.
You smell gas, see burnt wiring, or see blackened / charred hood areas.
The exhaust fan is missing, disconnected, or shaking violently.
The seller refuses to provide hood / fire / grease records.
You must add major cooking equipment outside the existing hood.
The landlord will not allow roof, gas, electrical, or grease-interceptor work.

Defined terms in this guide
The vocabulary worth knowing before you sign.
- Grease Interceptor
- An in-ground or in-line unit that separates fats, oils, and grease (FOG) from kitchen wastewater before it enters the sewer. Sizing follows the adopted plumbing code — rated flow for hydromechanical units, drainage fixture units for gravity interceptors under the UPC — plus the sewer utility’s FOG rules.
- Fats, Oils, and Grease· FOG
- The grease a kitchen sends to its interceptor; wok and fryer-heavy menus send more than a sauté line.
- Type I Hood
- A grease-rated commercial hood with grease filters and a fire-suppression system, built of steel or stainless steel. The mechanical code requires one where appliances produce grease or smoke (IMC 507; UMC Chapter 5); NFPA 96 sets matching hood, duct and suppression rules.
- Type II Hood
- A hood for appliances that give off heat, steam or combustion products but no grease or smoke — dishwashers and some ovens, kettles and steamers (IMC 507.3). Some small electric appliances are exempt when the HVAC design handles their heat and moisture.
- Authority Having Jurisdiction· AHJ
- The local government body that issues building permits and enforces code in a specific jurisdiction — typically the city building department; the fire marshal and health department are AHJs for their parts.
OTHER CUISINES
03
American Diner / Burger / Breakfast
Flat-top + fryer + bacon = heavy grease load; old grease interceptors rarely keep up.
02
Mexican / Tex-Mex
Comal + plancha lines and tortilla warmers are usually under-vented in inherited TI shells.
17
Mediterranean / Middle Eastern / Kabob
Vertical broiler + charbroiler combinations stack BTUs in ways inherited hoods rarely handle.
