Requirements for a Commercial Kitchen at Home: Guide

Last Updated on May 18, 2024 by Shari Mason

Choosing to establish a food service business from your home can offer both convenience and adaptability. Nevertheless, the concept of constructing a professional kitchen in your home and understanding the plethora of regulations and rules can sometimes appear overwhelming.

As a home cook looking forward to having a commercial kitchen at home, I’ve spoken to some local government authorities and relevant food safety agencies. 

To save you from the hassle, here are the simplified requirements for a commercial kitchen at home. 

8 General Requirements For A Commercial Kitchen At Home 

1. Zoning & Permits

Zoning & Permits for Commercial Kitchen At Home 

Based on my interview with one of the local government authorities near my location, constructing a commercial kitchen at home is no different in any food establishment.

If you operate your commercial kitchen at home, you have to secure local and state permits where you are located. 

There can be restrictions in urban areas, so it is best to check with the local zoning department if it is allowed to construct a commercial kitchen in your zoning designation. 

In addition, according to the FDA, any food business is subject to compliance with FDA, aside from state and local requirements [1].

2. Food Handling License 

A food handling license is a requirement for everyone who works in the food service establishment, including a commercial kitchen at home. 

A food handling license is a legal requirement that guarantees the health and safety of the consumers, especially in the sanitary aspect. 

According to the USDA, you can obtain a license or a food handler’s permit  from the local county health department. You can also obtain a food handling license from any ANSI-accredited training provider [2]. 

3. Separate Kitchen Space

Separate Kitchen Space

As an operator of a commercial kitchen at home, you must note that you will need a separate kitchen space specifically designated for commercial use.

You cannot use your residential kitchen as the kitchen space or an extension for your commercial kitchen. Also, you must consider the location of your commercial kitchen. 

“A successful home-based commercial kitchen hinges on this principle: separate the culinary dreams of business from the warmth of family life. Create a designated space where sizzling ambitions thrive, away from the heart of your home, ensuring the aroma of dreams won’t clash with the symphony of your family’s daily rhythm.”

Check where it is the most accessible existing plumbing location and build a separate kitchen space where the odors and noise will not interfere with your family’s daily lifestyle.

4. Adequate Space & Layout

Cleaning & Washing

There is no required layout for a commercial kitchen. However, a well-thought and designed establishment will optimize efficiency and performance of the commercial kitchen. 

In my conversation with a commercial kitchen owner, he emphasized the importance of having a separate cleaning and washing location to avoid cross-contamination. 

He mentioned that three-compartment sinks are necessary to clean utensils and keep the kitchen at full speed quickly.


Remember that your house is not an extension of your commercial kitchen, so plan a storage location to store goods. 

It is ideal to split your storage area into three parts: non-food, dry, and cold storage. The non-food storage can go on the cleaning and washing space. 

The non-perishables and pantry goods go to dry storage, while anything that needs to be chilled, refrigerated, and frozen goes to cold storage. 

Food Prep

Regarding food prep, you will need sinks and steel countertops for washing, cutting, and mixing.

Placing the tables near the storage area speeds up the process because you can efficiently grab and move it quickly. I recommend putting up sections designated for processing meats and sorting foods. 


You must consider where you will cook and the equipment sizes you will use (ovens, fryers, and ranges). You must ensure that the location has proper ventilation, lighting, and washable floors. 

You can break down the cooking area into smaller stations-frying, baking, and grilling. It should be near the finishing area to save time and easy access. But how much does it cost to start your own small restaurant?


The final section of the commercial kitchen is the finishing area, where you pack up the orders or serve the food to the consumers. 

It is commonly found on the front of the commercial kitchen to shorten the distance between the customers and completed meals. 

5. Ventilation And Exhaust System

A commercial kitchen at home should be adequately ventilated because it can be extremely hot. 

Food and cooking preparation produces steam, smoke, and airborne particles that can irritate the skin and eyes and cause respiratory issues that can harm your kitchen crew. 

If you have a proper exhaust and ventilation system, you can effectively remove the irritants and contribute to the temperature control of the kitchen. 

In addition, a proper exhaust and ventilation system can help reduce energy loss and restrict odors that may go into your home. 

6. Plumbing & Sanitation

Clean Water Supply

One of the primary purposes of plumbing is to provide an adequate and potable water supply to any establishment [3]. Since you will provide food products, a clean water supply is necessary. 

The health department must approve the clean water supply, which should be tested to ensure it is approved for food production. 

Inspection Of Gas Hookups

If you plan to construct a commercial kitchen at home, you must ensure that your gas hookups pass the inspection to avoid any untoward incident. 

Natural gas hookups in future construction are banned in Berkley, California, but let’s be clear, it’s not banned in the whole country [4]. 

“The court is saying that Berkeley was effectively regulating the energy efficiency … by banning new natural gas hookups,”

Amy Turner, Senior Fellow in Columbia Law School

Natural gas appliances help commercial kitchens operate efficiently and effectively, but every commercial kitchen (not within Berkley) must pass the inspection before they operate. 

7. Flooring & Walls

The flooring of your commercial kitchen at home should be made from non-porous, smooth, washable, but not non-slipping materials. It should be quickly disinfected because after every shift. 

In my interview with a commercial kitchen owner, he mentioned that investing in non-porous and vinyl walls is worth it. They are moisture-proof and easy to clean, which makes your kitchen contaminated-free.

8. Equipment & Appliances

Cooking Equipment

If you plan on putting up a commercial kitchen at home, know that you must invest in cooking equipment, which may vary depending on your restaurant’s needs. 

You may need a cabinet-like machine that will hold your range and oven to save space in your kitchen. Also, you will need a grill, broiler, toaster, microwave, griddle, and deep fryer.  

Beverage Equipment

If you offer beverages and drinks in your commercial kitchen at home, you will invest in beverage equipment like beverage dispensers, coffee machines, and ice machines. 

“In your home commercial kitchen, serve beverages with ease. Get sturdy equipment – dispensers, coffee makers, ice machines – built to handle the demand. Elevate your craft with reliable tools, ensuring every pour delights.”

It is ideal to get industry-grade beverage equipment to withstand the high-volume production that is required in commercial kitchens. 

Refrigerator And Freezer

Another requirement for a commercial kitchen at home is the refrigerator and freezer as cold storage to keep your ingredients safe to consume and maintain freshness. 

Storage Containers

Storage containers are necessary because you will need to store ingredients, especially if you prepare them beforehand. 

Three Sinks

Three sinks are required in a commercial kitchen because one is for handwashing, one for food washing, and the other for cleaning.

A dishwasher is a machine used to clean cookware and kitchenware. If needed, you must check the qualification of the dishwasher. 


Kitchenware such as knives, spatulas, pots, cutting boards, dishes, pans, and other cooking tools are necessary when opening a commercial kitchen at home.
