Restaurant Hood Cleaning
in Los Angeles, CA
Grease buildup in exhaust hoods is the leading cause of commercial kitchen fires. Regular cleaning removes accumulated grease before it becomes a fire hazard and keeps your kitchen in compliance with NFPA 96.
25,000 kitchens, five grease intensity zones
Los Angeles is one of the most complex restaurant markets in the world — over 25,000 licensed food establishments spread across 500 square miles of wildly different neighborhoods. For hood cleaning, the key variable isn't the city as a whole but the specific neighborhood and kitchen type. Koreatown runs some of the highest-grease-load kitchens in California, with charcoal and gas wok operations running 12+ hours daily. Downtown's Arts District hosts a dense cluster of high-end restaurants with elaborate kitchen builds. Hollywood and West Hollywood skew toward late-night high-volume operations that accumulate grease faster than the visible hours would suggest. East LA and Boyle Heights have concentrations of Mexican and Latin kitchens — carnitas, birria, and high-output fryers — that put consistent heavy load on hood systems. Each zone has a different cleaning cadence in practice.

What Restaurant Hood Cleaning costs in Los Angeles
Prices vary by job size. Here's where Boh sits across the typical range.
LAFD enforces NFPA 96 and Fire Code §57.118
NFPA 96 and Los Angeles Fire Code §57.118 require commercial kitchen exhaust systems to be cleaned based on cooking volume. LAFD is one of the most active hood cleaning enforcement bodies in California - compliance documentation must be current and on-site at all times. Koreatown and high-density Korean BBQ operations with charcoal and wok cooking are often cited for under-frequency cleaning.

Cadence by kitchen type — monthly to quarterly
Why LA kitchens call between scheduled visits
Hood cleaning in Los Angeles, answered
How often does LAFD actually require hood cleaning for a Koreatown Korean BBQ or wok kitchen
Monthly. Los Angeles Fire Code §57.118 and NFPA 96 both require monthly cleaning for solid-fuel and high-output wok operations. Quarterly schedules that work for a West Hollywood bistro will put a charcoal BBQ operation out of compliance within weeks.
What is the fine if LAFD finds my hood cleaning documentation is not current
LAFD can issue a fine of up to $1,000 per violation for non-compliant exhaust systems. Documentation must be on-site — not in an email or a cloud folder your staff can't access — at all times.
My building in the Arts District was converted from an industrial space. Does that affect duct cleaning
Yes. Historic conversions in DTLA and the Arts District frequently have non-standard duct runs, limited access panels, and longer duct paths to roof exhausts. Budget for longer service windows and ask your technician to flag any sections requiring new access panels before cleaning day.
What does a hood cleaning in Los Angeles cost
For a single-hood low-volume kitchen, expect $600–$780 through Boh. A mid-size operation with one or two hoods runs $900–$1,280. Large kitchens with three or more hoods — common in the Arts District and Hollywood — run $1,400–$2,100. High-volume and live-fire kitchens at the top of those ranges reflect longer cleaning windows and heavier grease loads.
Why does Boh price below what my current vendor charges
Boh aggregates volume across thousands of LA kitchens, which gives vetted vendors predictable pipeline in exchange for preferential pricing. That discount passes to the operator, not the vendor's margin. There's no sourcing markup layered on top.
What's actually included in that price and what would cost extra
Boh's scope covers the full hood canopy, ductwork, exhaust fan, and vents, plus a belt and motor inspection, before-and-after photos, and the compliance tag. Access panel fabrication for older Koreatown or Hollywood buildings, and suppression system re-certification after an Ansul discharge, are separate line items — the technician will flag these before starting.
What should I do if LA County Environmental Health cites me for grease buildup during a routine inspection
Schedule a professional cleaning immediately and get the dated service tag affixed before your re-inspection. LA County inspectors want to see physical documentation on-site, not a promise that cleaning is scheduled. Boh uploads before-and-after photos to your account so you have a defensible paper trail.
How does ghost kitchen density in Hollywood affect cleaning frequency
Ghost kitchens in Hollywood and the Fairfax corridor often run multiple high-volume concepts out of a single hood system, compressing a week's worth of cooking into a smaller physical footprint. That load pattern pushes most ghost kitchen hoods into monthly rather than quarterly territory — verify your actual cooking hours with your cleaning tech, not the kitchen's public-facing schedule.
