Commercial Kitchen Utility Planning Checklist

A kitchen can have the right equipment and still encounter delays if the building services don’t match what that equipment requires. The electrical service may not support the calculated load, the gas system may be undersized, or the drainage layout may conflict with the final equipment plan.

This guide explains the main utility categories involved in commercial kitchen planning and how a kitchen equipment utility schedule brings them together.

Key takeaways

• Start preliminary utility planning as soon as the equipment list is drafted.
• Verify final requirements using the selected models’ current specification sheets and installation manuals.
• Record voltage, phase, current draw, gas input, water connections, waste requirements, and ventilation coverage.
• Size gas piping as a complete system rather than appliance by appliance.
• Update the utility schedule whenever equipment is substituted or specifications change.

What Is Commercial Kitchen Utility Planning?

Commercial kitchen utility planning is the process of matching proposed equipment with the building services needed to install and operate it. Model-specific information determines the location and capacity of outlets, disconnects, gas stub-outs, water lines, drains, waste receptors, and ventilation systems.

Foodservice consultants and design teams often organize this information in a utility schedule, also called a rough-in schedule or connection plan. Each numbered equipment item is listed with its electrical, gas, water, drainage, and ventilation requirements. Architects and engineers can then design the mechanical, electrical, and plumbing systems around the equipment plan.

This coordination should happen before rough-in work begins. A fryer battery may increase gas demand beyond the capacity of existing piping, while a substituted reach-in refrigerator may need a different voltage or circuit. Resolving these issues during design is usually easier than modifying finished construction.

What Are Commercial Kitchen Electrical Requirements?

Electrical planning begins with each unit’s voltage, phase, current draw, connection type, and circuit requirements. A code-compliant load calculation can then determine whether the building service and electrical panels have enough capacity.

Some countertop appliances and small refrigeration units operate on 120-volt circuits. Cooking equipment, dishmachines, compressors, and other higher-load equipment may require 208, 240, or another specified voltage in single-phase or three-phase service. Use the current specification sheet, data plate, and installation manual to confirm the correct requirements.

Connection placement matters as much as electrical capacity. Receptacles and disconnects should remain accessible without obstructing cleaning, ventilation, or service access. Cords shouldn’t be stretched, routed through doorways, or positioned where they’re likely to be damaged.

Ground-fault circuit-interrupter protection is a jurisdiction-specific question. Section 210.8(B) of NFPA 70, the National Electrical Code, addresses GFCI protection in commercial kitchens and other non-dwelling locations. Receptacle rating, voltage, location, and the edition adopted by the jurisdiction determine what applies to a particular project.

How Should Restaurant Gas Line Planning Work?

Restaurant gas line planning evaluates the complete system, including the meter, regulator, piping, fittings, appliance loads, and required pressure.

Document the rated gas input of every connected appliance. A licensed gas fitter or mechanical engineer can use those ratings with the applicable demand calculation, fuel type, allowable pressure drop, piping material, equivalent pipe length, and fitting losses to size the system under the adopted fuel-gas code.

Undersized piping may have difficulty maintaining the required pressure when several appliances operate at once. This can contribute to weak flames, unreliable ignition, or slow recovery in commercial gas fryers, even when individual appliances appear to work normally during testing.

Natural gas and propane models can use different operating pressures and burner components. Some appliances may be converted only with a manufacturer-approved kit and qualified service, while others aren’t designed for field conversion. Confirm the fuel type before ordering.

Commercial gas foodservice equipment may be certified to CSA/ANSI Z83.11:25/CSA 1.8:25, a standard covering appliances such as ranges, ovens, fryers, kettles, and steam cookers. Appliance certification doesn’t establish that the site connection or installation complies with local requirements. Empura’s Commercial Gas Fryer Installation Guide explains how these considerations apply to an individual gas appliance.

Movable gas equipment may also need a connector listed to ANSI Z21.69-2015 (R2025)/CSA 6.16-2015 (R2025) and a separate restraining device. The restraint limits movement that could place strain on the connector. Its location should be planned around the gas shutoff and equipment service access.

What Are Commercial Kitchen Plumbing Requirements?

Plumbing planning covers water supply, fixture requirements, water heating, and protection of the potable water system.

Hot and cold connections may be needed for compartment sinks, hand sinks, dishmachines, ice machines, beverage equipment, and steam equipment. Their placement should support the kitchen’s workflow while meeting locally adopted food, plumbing, building, and accessibility requirements.

The 2022 FDA Food Code shows why local confirmation matters. Section 5-202.12(A) changed the model minimum temperature for water delivered at a handwashing sink from 100°F to 85°F. The Food Code is a model offered for adoption by regulatory authorities, not a single federal requirement governing every establishment. The applicable edition and local amendments determine the requirement for a specific project.

Backflow protection should also be identified early. Carbonators, chemical dispensers, hose connections, and certain equipment may require an air gap, vacuum breaker, backflow preventer, or another approved method. The appropriate protection depends on the connection type and the plumbing code adopted by the jurisdiction.

Water-heating calculations should account for required temperatures, storage capacity, recovery rate, and peak demand, including equipment with built-in booster heaters. An undersized system may be unable to provide the required temperature or volume during busy periods.

What Does Commercial Kitchen Drainage Involve?

Commercial kitchen drainage planning determines how wastewater reaches the sanitary system, whether equipment requires a direct or indirect connection, where waste receptors will be located, and how grease-laden wastewater will be managed.

Commercial ice machines, food-preparation fixtures, and some warewashing equipment commonly discharge indirectly through an air gap or air break into an approved receptor. Depending on the application and local code, the receptor may be a floor sink, floor drain, standpipe, or another approved fixture.

Waste-receptor locations should account for equipment legs, casters, drain outlets, cleaning access, and service clearances. These locations are especially important to confirm before concrete is placed.

Drainage piping must also maintain the required slope. Table 704.1 of the 2018 International Plumbing Code specifies a minimum slope of ¼ inch per foot for horizontal drainage piping 2½ inches or smaller and ⅛ inch per foot for piping from 3 through 6 inches. The applicable requirement depends on pipe diameter and the code adopted by the jurisdiction.

Grease-interceptor requirements vary based on the fixtures served, interceptor type, flow rates, drainage-fixture-unit values, locally adopted plumbing code, and sewer-authority rules. ASME A112.14.3-2022/CSA B481.1:22 covers testing, performance, rating, sizing, location, and installation requirements for hydromechanical grease interceptors.

For gravity grease interceptors, Section 1003.3.7 of the 2021 International Plumbing Code requires at least 30 minutes of retention time at the calculated peak flow rate. The applicable standard and sizing method depend on the interceptor type and local requirements.

Determining which fixtures must discharge through an interceptor, along with its size and location, should be part of the initial plumbing plan. Poorly sized or maintained interceptors can contribute to grease accumulation, slow drainage, backups, odors, and sewer-compliance problems.

How Does Ventilation Factor Into Utility Planning?

Ventilation must be planned with the equipment layout because hood coverage, exhaust, makeup air, controls, and fire suppression depend on the cooking lineup.

Equipment that produces grease or smoke generally requires a Type I hood unless a code exception or listed recirculating system applies. Hood design may depend on the cooking process, appliance duty, equipment dimensions, hood type, required overhang, exhaust rate, makeup air, and equipment listings.

NFPA 96 addresses ventilation control and fire protection for commercial cooking operations. The International Mechanical Code’s commercial kitchen exhaust provisions also cover hood requirements and system design. The locally adopted code editions, equipment listings, and manufacturer instructions govern the final installation.

The proposed equipment lineup should be sufficiently defined before the ventilation system is finalized. Substituting a different appliance model can change hood coverage, exhaust, clearance, or fire-suppression requirements. Empura’s Commercial Kitchen Equipment Checklist by Restaurant Type explains how menu, production volume, service model, utilities, and available space shape that lineup.

Ventilation systems can create additional utility needs. Hoods, exhaust fans, makeup-air units, controls, and fire-suppression systems may require electrical connections, interlocks, or gas shutoff coordination. Listed water-wash hoods may also need water and drainage connections.

• Verify access to shutoffs, disconnects, filters, service panels, and removable components.
• Compare final rough-ins with the latest equipment documents.
• Recheck the schedule after any model, specification, or fuel-type change.

Bringing It Together: The Utility Schedule

A utility schedule gives the project team one coordinated reference. It typically records:

Before rough-in work begins, compare the schedule with the latest equipment cut sheets, installation manuals, and design drawings. Clearly identify each revision so every trade works from the same equipment list.

Conclusion

Commercial kitchen utility planning turns an equipment list into a coordinated installation plan. Electrical capacity, gas piping, water supply, drainage, grease management, and ventilation all depend on decisions made before equipment arrives.

A utility schedule based on current model documentation gives architects, engineers, contractors, and equipment suppliers a shared reference. Keeping it current also makes substitutions easier to evaluate before they create conflicts in finished construction. Final system designs and installations should be reviewed by the appropriate professionals and local authorities.
