Why Storefronts Make Sense for Commercial Kitchens
Starting a food business traditionally meant building or leasing a commercial kitchen from scratch — a process costing $150,000 to $500,000 and taking 6 to 12 months. Converting an existing storefront is faster and cheaper because the shell already exists: you have four walls, a roof, electrical service, plumbing connections, and often existing restrooms. The conversion focuses on installing kitchen-specific systems inside an already functional commercial space.
The rise of food delivery services, ghost kitchens, meal prep companies, and cottage food businesses has created strong demand for affordable commercial kitchen space. A converted storefront can serve as your own production kitchen, a shared/rental kitchen generating hourly rental income, or a combination of both.
Total Cost Range
A complete storefront-to-commercial-kitchen conversion costs $75,000 to $250,000 depending on size, existing infrastructure, equipment choices (new vs used), and local health department requirements:
Small kitchen (under 1,000 sqft): $75,000 to $125,000. Suitable for a single food business, meal prep company, or small bakery.
Medium kitchen (1,000-2,000 sqft): $125,000 to $200,000. Suitable for a restaurant production kitchen, catering company, or shared kitchen with 2-3 tenants.
Large shared kitchen (2,000+ sqft): $175,000 to $250,000+. Multiple cooking stations, walk-in storage, and dedicated prep areas for rental to multiple food businesses.
Cost Breakdown by Category
Grease trap and plumbing: $10,000 to $25,000
Every commercial kitchen requires a grease trap (also called a grease interceptor) to prevent fats, oils, and grease from entering the municipal sewer system. The size of the grease trap depends on your kitchen volume and local requirements. Installation involves cutting into the floor slab, installing the trap, and connecting it to the sewer line. Budget $5,000 to $15,000 for the grease trap alone. Additional plumbing includes a three-compartment sink (required by health code), a hand-washing sink, and water supply connections for equipment.
Ventilation and hood system: $15,000 to $40,000
A commercial exhaust hood with a fire suppression system is required over any cooking equipment that produces smoke, steam, or grease-laden vapors. The hood must be sized to cover all cooking equipment and connect to a rooftop exhaust fan. The fire suppression system (typically Ansul or similar) automatically activates if a grease fire occurs. This is one of the most expensive single components and is non-negotiable for health department approval.
Electrical upgrade: $8,000 to $20,000
Commercial cooking equipment draws massive power. A small kitchen needs at least 200-amp service. A medium or large kitchen may need 400-amp or higher. Most storefronts have 100 to 200-amp service, so an upgrade is almost always required. Budget for the panel upgrade, dedicated circuits for each major appliance, and GFCI outlets throughout.
Commercial cooking equipment: $20,000 to $80,000
New commercial equipment is extremely expensive. Used equipment from restaurant auctions and liquidation sales costs 30 to 60% less and is the smart choice for most new food businesses. Essential equipment includes a commercial range, oven, fryer (if applicable), reach-in refrigerator, reach-in freezer, walk-in cooler (for larger kitchens), prep tables, and a three-compartment sink.
Flooring: $5,000 to $12,000
Commercial kitchen floors must be non-slip, waterproof, and easy to sanitize. Quarry tile is the traditional choice. Epoxy-coated concrete is more affordable and equally functional. The floor must slope toward floor drains for proper drainage during cleaning.
Walls and ceiling: $5,000 to $10,000
Health codes require walls and ceilings in food preparation areas to be smooth, non-porous, and easy to clean. FRP (fiberglass reinforced panel) is the standard for walls. Ceiling tiles must be washable and moisture-resistant.
Permits and inspections: $5,000 to $15,000
Budget for a building permit, health department plan review and inspection, fire marshal inspection, grease trap permit, and business license. The health department plan review is the most critical — submit your kitchen layout for approval before starting construction. Changes required after construction are extremely expensive.
Revenue Potential
Shared kitchen model: Rent kitchen time to food businesses at $20 to $50 per hour. A kitchen booked 60 hours per week generates $5,000 to $12,000 per month.
Ghost kitchen model: Operate delivery-only food brands from the kitchen. Multiple brands can operate from the same kitchen, each targeting different cuisine types on delivery apps.
Own production: Use the kitchen for your own food business (catering, meal prep, bakery, packaged food) with full control of the schedule.
