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 = 200 lbs of oil cycling. That generates 2× the FOG (fats/oils/grease) load of a sandwich shop. Most municipalities require interceptor sizing per fixture units; a 4-vat line typically needs 1,500+ gallon capacity. Inherited 750-gallon traps fail in 6 months — confirm AHJ sizing before lease.
02 · Pressure-fryer gas + ventilation
A Henny Penny or Broaster pressure fryer is gas-fired at 80K BTU and emits high-pressure steam during release. Most general-rated Type I hoods don't handle the pressure release plume; spec a high-velocity hood with explicit pressure-fryer compatibility, plus a dedicated 1" gas drop, not a tee off the existing line.
03 · Breading station + flour dust
Hand-breading stations release flour into the air. Without dedicated breading-zone exhaust (Type II low-velocity hood) the dust coats walk-in evaporator coils within weeks, causing premature compressor failure. Plan a 4' Type II hood over the breading table; cheap insurance.
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. AHJ + DOT typically require 10-car minimum stack length before the order point. Inherited strip-mall lots rarely meet this. Confirm stack length, exit lane geometry, and any traffic-engineer letter required 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 tank that separates fats, oils, and grease (FOG) from kitchen wastewater before it enters the sewer. Sized per IPC §1003 fixture-unit math.
- Fats, Oils, and Grease· FOG
- The grease load a kitchen sends to its interceptor. Wok cooking generates 2–3× the FOG of a sauté line; fried-chicken 4-vat lines generate more again.
- Type I Hood
- A grease-rated commercial exhaust hood with stainless construction, filter banks, and fire-suppression integration. Required over all grease-producing appliances per NFPA 96.
- Type II Hood
- A low-velocity hood rated for steam, heat, and odor — but NOT grease. Used over dishwashers, steam tables, ovens that vent steam only.
- Authority Having Jurisdiction· AHJ
- The local government body that issues building permits and enforces code in a specific jurisdiction — typically the city building department.
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.
