Restaurant design is among the most complex and regulated types of commercial architecture. Seattle has specific requirements from multiple regulatory agencies, building department, fire marshal, Seattle-King County Public Health, and liquor control, and they all must be satisfied before you open.
Seattle Restaurant Design Requirements
Type 1 hood:
Required over commercial cooking equipment producing grease-laden vapors. Requires mechanical drawings and fire marshal approval.
Grease interceptor:
Required for all food service establishments with cooking. Must be sized and located per plumbing code.
ADA restrooms:
Required with accessible route from entrance and dining area.
Seating capacity:
Determines occupancy type (Assembly A-2), which triggers additional egress and sprinkler requirements.
Health department review:
Seattle-King County Public Health reviews construction documents separately from the building permit.
