WHERE THIS CUISINE QUIETLY COSTS YOU MONEY

Thai / Vietnamese / Southeast Asian-specific conversion gotchas

  • 01 · Stock-pot range BTU + hood capture

    A pho or tom yum stock-pot range runs two 80K–120K BTU burners under 60-quart pots for 18+ hours a day. That's a sustained 200K BTU heat load directly under the hood — different from a sauté line's peaks. Hood capture velocity, MUA, and even the gas-meter sizing belong in the design conversation early.

  • 02 · Wok station alongside stock pots

    Thai stir-fry needs a 100K+ BTU wok burner. Co-locating wok + stock pots under one hood is fine IF the hood is sized for both worst cases combined. Many inherited hoods were sized for the previous tenant's sandwich grill — the gap can be 1,500–3,000 CFM. Plan for a full hood replacement budget if you're re-tenanting.

  • 03 · Fresh-herb + produce cold prep

    Cilantro, Thai basil, bean sprouts, mint, lime — heavy daily produce volume that lives 3–5 days max. A single small reach-in won't hold the par. Plan a 6×8 walk-in minimum with a dedicated produce shelf, and prep tables with built-in refrigerated rails for the make-line.

  • 04 · Fish sauce + neighbor odor

    Bulk fish sauce, fermented shrimp paste, and aged tamarind have aggressive odor signatures. A shared HVAC return between kitchen and dining room (or worse, a shared exhaust with a neighboring tenant) creates lease-violation complaints. Specify negative-pressure kitchen and zero return-air sharing.

  • 05 · Boba / Thai-tea sweetener handling

    If the menu includes Thai tea or boba, you're also handling sticky sweetener syrups and tapioca pearls — which dump organic load into floor drains and clog them within months. Run separate floor drains in the beverage station, not shared with the main kitchen drain, and budget for jetting.

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.

BTU (British Thermal Unit)· BTU
A unit of heat. Gas cooking appliances are rated by input in BTU per hour (BTU/h): a home burner is roughly 12,000 BTU/h; a commercial wok burner typically 100,000–150,000 BTU/h.
CFM (Cubic Feet per Minute)· CFM
The volumetric flow rate of an exhaust hood or make-up air unit. A typical commercial pizza hood pulls 1,500–2,500 CFM; a high-BTU wok hood can pull 4,000+ CFM.
Make-Up Air· MUA
Outside air brought in to replace what the hood exhausts. The mechanical code requires make-up air roughly equal to the exhaust (IMC 508.1); a dedicated, tempered unit typically supplies most of it, the rest transferred from the dining room.
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.
Capture Velocity
The air speed needed at the hood edge to pull in rising cooking effluent. Codes set no single capture-velocity number: unlisted hoods use the mechanical code’s minimum CFM per linear foot (IMC 507), listed hoods their listed airflow, and a capture-and-containment test confirms it.
