Arizona · Chinese / Wok
Convert a chinese / wok concept in Arizona.
Phoenix Chinatown (north of downtown) + East Valley clusters with high-BTU wok lines that stress inherited hoods.
Arizona · permitting context
What the state adds on top.
Climate Zone 2B (hot-dry) for the Valley means make-up air units have to dehumidify AND temper to ~78°F supply. A 4,000-CFM wok or wood-oven hood that comes with a 4,000-CFM MUA unit untempered will pull the dining room to 95°F by mid-July. Every meaningful Phoenix restaurant conversion budgets a tempered MUA — typically $8K–$15K above the "no MUA" line item the GC quotes from a Midwest catalog.
Plan-check rhythm: Phoenix DSD averages 4–6 business days on first review for a typical TI; Mesa and Scottsdale run 3–5; Chandler and Tempe lean 5–7. None of the Maricopa AHJs accept over-the-counter for restaurant TI larger than 500 SF — every project goes through full plan review. Tucson and Flagstaff add a 2–4 day handoff because the AHJ counters do not pre-screen for completeness the way Phoenix DSD does; a missed cover-sheet field becomes a full correction cycle.
Grease interceptor rules vary materially: Phoenix and Mesa enforce IPC §1003 sizing via FSE (Food Service Establishment) review separate from building plan-check; Scottsdale puts it inside the same plan-check stack. The result is that two restaurants 8 miles apart can have a 3-week difference in permitting timeline based on interceptor sizing alone. Walk the existing interceptor with a tape measure before you sign.
Hood + MUA rule for Arizona
Type I hoods under wok / charbroiler / tandoor / wood-oven loads need 80–85% tempered MUA in Arizona — climate zone 2B humidity penalty is real. Plan stainless behind any solid-fuel appliance and confirm gas-meter capacity (≥425 CFH for a 600K-BTU line) before lease signing.
AHJ quirk
Phoenix DSD is the most predictable Valley AHJ — first review consistently lands in 4–6 business days and corrections are line-numbered. Outside the Valley, Tucson and Flagstaff don't pre-screen for completeness, so a missed cover-sheet field forces a full second cycle.
CHINESE / WOK · WHERE THIS CUISINE QUIETLY COSTS YOU MONEY
Chinese / Wok specifics, on top of the state rules.
01 / 5
Wok-range BTU load
A single 16" wok burner runs 100,000–150,000 BTU; a four-burner Chinese range commonly hits 600,000+ BTU. The hood, exhaust fan, and gas service in the previous tenant's set-up almost certainly weren't sized for that. Confirm hood CFM, exhaust duct size, and gas-meter capacity BEFORE signing.
02 / 5
Make-up air sizing
For every CFM the hood exhausts, you need a matching CFM coming in — typically 80–85% of exhaust as a dedicated tempered MUA unit. A 4,000 CFM wok hood with no MUA pulls negative pressure through the front door, slams it, and chases customers out. MUA is often an extra $8K–$15K conversion line item.
03 / 5
Stainless wall behind the wok
Code (and insurance) require non-combustible wall + ceiling surfaces within ~36" of any wok burner. Drywall behind the previous tenant's pizza oven won't pass — budget for stainless sheet or fire-rated tile across the whole back wall.
04 / 5
Wok-water drainage
Wok stations use a constant cool-water spray to keep the ring temperature down — that water has to go somewhere. Most wok ranges ship with a built-in 2" floor drain requirement. If the existing slab doesn't have a drain in the right spot, you're saw-cutting concrete (~$3K–$8K + permit).
05 / 5
Grease load + interceptor sizing
Wok cooking generates 2–3× the grease load of grill or sauté. The previous tenant's grease interceptor was probably sized for that operation, not a wok line. Many AHJs require resizing under IPC Section 1003 — expect a 1,000+ gallon interceptor + a pump-out frequency increase from quarterly to monthly.
