St. Louis County food-facility health permits run about $75–$130 annually, depending on size or sales volume. Plan review runs about $210. Confirm the exact amount with St. Louis County Department of Public Health - Food & Environmental Program before you budget.
Confirm the authority for your exact address. Some cities run their own health division, and building, planning, fire, sewer/grease and business-license approvals are separate even when St. Louis County Department of Public Health - Food & Environmental Program issues the health permit.
Cities with their own health department: Chesterfield, Florissant, Clayton, Kirkwood, Ballwin, Maryland Heights, Wildwood, Town and Country. Food businesses inside these cities apply to the city health department (with its own fees and rules), not St. Louis County. Confirm which authority covers your exact address.

A code-compliant kitchen in St. Louis County needs more than the health permit — these approvals are handled by separate offices. Confirm current requirements with each.
food establishments here must control fats, oils & grease (FOG) with a grease interceptor or trap, and typically register with the local sewer/wastewater authority. Grease interceptors are required by locally adopted plumbing codes and municipal FOG programs, as Missouri has no statewide plumbing code.
Size the interceptor with our grease-trap sizing calculator, compare units in the grease-trap catalog, and confirm the local FOG permit with St. Louis County Department of Public Health - Food & Environmental Program (contact above).
Hood fire suppression: commercial cooking under a Type I hood needs a wet-chemical suppression system to NFPA 96, permitted and inspected by the local fire marshal. Commercial kitchen hood suppression follows NFPA 96 and locally adopted fire codes, as Missouri has no statewide fire code. See do I need a hood? and the hood CFM calculator.
Backflow prevention: Restaurants must install a testable backflow preventer (typically an RPZ) that is tested annually and reported to the local water utility. A certified backflow assembly (often an RPZ) on the water service, tested annually, is standard — confirm with your water utility.
