A restaurant kitchen is one of the most electrically demanding commercial spaces you can build. Between commercial ovens, fryers, refrigeration units, dishwashers, exhaust hoods, and HVAC systems, even a modest restaurant in Metro Atlanta can require 400 amps or more of electrical service. Getting the electrical plan right from the start protects your investment, keeps your staff safe, and prevents the kind of code violations or failed inspections that delay your opening.
If you are planning a restaurant build-out or renovation in Lawrenceville, Duluth, Snellville, Lilburn, or anywhere in Gwinnett County, the electrical scope will likely be one of the largest line items in your budget. Older commercial spaces in these areas were often built for much lower power demands, which means an electrical service upgrade and extensive new wiring are common parts of the process. Understanding what is required before you sign a lease or start demolition can save you weeks of delays and tens of thousands of dollars in unexpected costs. If your restaurant space is in Duluth, working with a Duluth commercial electrician early in the planning process helps you scope the electrical work accurately.
Why Commercial Kitchen Power Demands Are So High
A single residential kitchen might draw 40 to 60 amps across all its appliances. A full-service restaurant kitchen can easily draw 200 to 400 amps for cooking equipment alone, before you factor in HVAC, lighting, and the dining room. Commercial fryers, convection ovens, ranges, steam tables, walk-in coolers, and dishwashers each pull significant amperage, and most of them need to run simultaneously during service.
This is why the National Electrical Code (NEC), published as NFPA 70, requires careful load calculations for commercial kitchens. Articles 210 and 220 of the NEC govern how branch circuits and feeders must be sized to match the connected load. In practical terms, this means nearly every major piece of kitchen equipment needs its own dedicated circuit, a branch circuit that serves only that one appliance. Dedicated circuits prevent overloading, reduce nuisance breaker trips during a busy dinner rush, and lower fire risk.
Georgia adopts the NEC as part of its statewide minimum standard codes. Most Metro Atlanta jurisdictions currently enforce the 2020 edition, with some transitioning to the 2023 edition. Your licensed electrical contractor should know exactly which version your local building department is enforcing.
Dedicated Circuits, GFCI Protection, and Hood Interlocks
Dedicated Circuits for Every Major Appliance
If you are planning your equipment list, assume that each of the following will need its own dedicated circuit: commercial ovens, ranges, griddles, fryers, dishwashers, ice machines, walk-in coolers, walk-in freezers, and steam tables. Smaller countertop equipment can sometimes share a circuit, but only after a proper load calculation confirms it is safe to do so.
An undersized or overloaded electrical panel is one of the most common problems restaurant owners encounter in older Gwinnett County commercial spaces. If you are wondering whether your existing panel can handle additional circuits, the answer usually depends on both the panel’s total amperage and its physical space for new breakers. In many older build-outs, the answer is no, and a service upgrade becomes necessary.
GFCI Protection Where Water Meets Electricity
GFCI stands for Ground-Fault Circuit Interrupter, a device that cuts power almost instantly if it detects electrical current leaking to ground, which often means through a person. Commercial kitchens are wet environments with metal surfaces, standing water, and staff handling electrically powered equipment with wet hands. The NEC (Section 210.8(B)) requires GFCI protection on all 125-volt, single-phase, 15- and 20-ampere receptacles in commercial kitchens. This is not optional, and health inspectors look for it too.
Exhaust Hood Electrical Interlocks
Commercial cooking exhaust hoods do more than vent smoke. They remove grease-laden vapors that are a serious fire hazard. NFPA 96, the standard for ventilation control and fire protection of commercial cooking operations, requires that your exhaust hood fans be electrically interlocked with the cooking appliances they serve. This means the hood must be running whenever the equipment beneath it is turned on. The makeup air unit, which replaces the air the hood exhausts, is typically interlocked as well. Your electrical contractor will wire these interlock controls as part of the hood installation, and your fire marshal will verify they work before you open.
Health Inspections and How Electrical Work Affects Them
Many restaurant owners think of electrical and health inspections as separate concerns. They are not. The Gwinnett County Health Department and other local health authorities follow standards based on the FDA Food Code, adopted by the Georgia Department of Public Health. While health inspectors do not check your wiring methods, they absolutely verify that your electrically powered equipment is functioning correctly.
Refrigeration units must hold proper temperatures. Dishwashers must reach sanitizing temperatures. Food prep and storage areas must have adequate lighting, typically measured in foot-candles. Ventilation systems must operate correctly to maintain air quality and prevent grease buildup. If your electrical system cannot reliably power this equipment, you will fail your health inspection regardless of how well the rest of your kitchen is built.
Faulty or non-compliant electrical work can also trigger building code violations that delay your certificate of occupancy. Understanding common electrical code violations in Atlanta before your build-out begins helps you avoid surprises during the inspection process.
Permits, Inspections, and Georgia Licensing Requirements
All commercial electrical work in Georgia requires a permit. There are no exceptions for “small” jobs in a restaurant. Whether you are adding a single dedicated circuit or wiring an entire kitchen from scratch, your local building department (the City of Lawrenceville, Gwinnett County Department of Planning and Development, or whichever jurisdiction applies) must issue an electrical permit before work begins.
Permitted work is then inspected at key stages, typically a rough-in inspection (before walls are closed up) and a final inspection. If the work does not pass, it must be corrected and re-inspected. This process can add several weeks to your timeline, so build it into your construction schedule.
Georgia law requires that all commercial electrical work be performed by a contractor holding a valid Georgia electrical contractor license. This is not a suggestion. Unlicensed electrical work is illegal in Georgia, will not pass inspection, can void your insurance, and puts your employees and customers at genuine risk. When evaluating contractors, verify their license and confirm they have specific experience with commercial kitchen installations, not just residential work.
What Restaurant Build-Outs Actually Cost in Metro Atlanta
Electrical costs for a restaurant build-out vary significantly based on the size of the kitchen, the number and type of equipment, the condition of the existing infrastructure, and whether a service upgrade is needed. Here are realistic ranges for the Metro Atlanta market.
Minor upgrades or repairs, such as adding a few dedicated circuits or replacing a subpanel, typically fall in the $1,500 to $5,000 range. Medium-scale renovations involving a service upgrade, multiple new circuits, and updated lighting might run $10,000 to $50,000. A full build-out of a new restaurant, including designing and installing the complete electrical system, commonly ranges from $50,000 to $200,000 or more depending on scope.
Several factors push costs higher: the need for three-phase power or 480-volt service, extensive conduit runs (required by code for most commercial wiring), older buildings with outdated infrastructure, tight or hard-to-access spaces, and rushed timelines. Costs come down when the existing service is already adequate, access is easy, and the owner provides clear, detailed equipment specifications early in the planning process.
Georgia Power offers commercial energy efficiency programs that may include rebates for LED lighting upgrades and high-efficiency equipment. Check their current commercial programs before finalizing your budget, as these incentives can offset a portion of your costs. Consult a tax professional about any federal business energy tax credits that might apply to your specific upgrades.
Planning Your Build-Out to Avoid Costly Surprises
The single most valuable step you can take before signing a lease or starting demolition is hiring a licensed commercial electrician to assess the space. This assessment reveals the existing service capacity, the condition of the wiring, how much panel space is available, and what upgrades you will need. Discovering that a building needs a $30,000 service upgrade after you have already signed a five-year lease is a painful and avoidable surprise.
Bring your full equipment list, including manufacturer specification sheets with voltage and amperage requirements, to your initial consultation. This allows your electrician to perform an accurate load calculation and design a system that handles your opening-day needs with room for future growth. Restaurant owners frequently underestimate their power demands, assuming what worked for the previous tenant will work for them. It often will not, especially if you are adding higher-powered equipment or expanding the kitchen footprint.
If you are taking over a space in an older part of Lawrenceville, Lilburn, or Duluth, plan for the possibility that the existing wiring does not meet current code. Older commercial buildings in Gwinnett County were built for lighter electrical loads, and bringing them up to the current NEC is a standard part of most restaurant renovations. Atlanta’s storm season and summer heat also make commercial-grade surge protection a smart investment; a single lightning strike or grid fluctuation can destroy thousands of dollars in kitchen equipment.

Frequently Asked Questions
Does every piece of kitchen equipment need its own dedicated circuit?
Most high-power commercial kitchen appliances, including ovens, fryers, ranges, dishwashers, walk-in coolers, and ice machines, require their own dedicated branch circuits under the NEC. Smaller countertop appliances may share a circuit in some cases, but only after a licensed electrician performs a load calculation to confirm it is safe and code-compliant.
What happens if my restaurant fails an electrical inspection in Gwinnett County?
If your electrical work does not pass inspection, the inspector will note the specific deficiencies. Your licensed electrical contractor must correct those issues and schedule a re-inspection. The work cannot be officially approved, and you typically cannot receive a certificate of occupancy, until all inspections pass. This is why hiring an experienced commercial electrician from the start saves time and money.
Can I do any of the electrical work in my restaurant myself to save money?
For commercial properties in Georgia, virtually all electrical work must be performed by a contractor holding a valid Georgia electrical contractor license. This includes adding outlets, running new circuits, installing fixtures, and any panel work. Attempting to do commercial electrical work yourself is illegal, will fail inspection, can void your insurance, and creates serious safety risks for your staff and customers.
