OBC DIVISION B · PART 3 · SECTION 3.7 — HEALTH REQUIREMENTS

What does the Ontario Building Code require for food premises like restaurant kitchens?

Food preparation areas need durable, easily cleaned floor, wall and ceiling surfaces and adequate sanitary facilities for staff. Building Code health requirements operate alongside Ontario's Food Premises Regulation (O. Reg. 493/17), which local public health units enforce.

Code reference
Health requirements for spaces where food is prepared, processed or served address sanitary construction: surfaces that are smooth, non-absorbent and readily cleanable, appropriate plumbing fixtures including hand-washing facilities, and separation of food areas from sources of contamination. Detailed operational requirements for equipment, temperatures and food handling come from public health legislation rather than the Building Code.
OBC Division B, Section 3.7.

What this means in practice

For restaurant, commissary and institutional kitchen projects, run two parallel approval tracks: the building permit under the OBC and a review by the local public health unit under O. Reg. 493/17. Practical must-haves include dedicated hand sinks in prep areas, mop or service sinks, washable wall and ceiling finishes, coved or sealed flooring, and grease interceptors under the plumbing code. Kitchen exhaust and fire suppression bring in NFPA 96 requirements, which are a common late-stage coordination gap.

Plain language

Commercial kitchens must be built so they can actually be kept clean: washable floors, walls and ceilings, plus proper sinks for hand washing. The building code sets the construction side, and local health inspectors enforce the day-to-day food safety rules.
