How to Build a Commercial Kitchen in your Garage


Many people dream of starting their own restaurant or bakery and have found a cost-efficient alternative in starting their food-based business at home. There really is no better time to develop your work from home business and this guide will help you create a good-sized commercial kitchen in your garage. This can save you money when it comes to rent and actual building costs but there are lots of rules and regulations to be aware of.

When you build a commercial kitchen in your garage you need to become familiar with the laws and guidelines set out by your state. Understanding the regulations will give you a solid foundation for your new kitchen. You can then create your dream kitchen knowing you are working within the rules.

What Makes a Commercial Kitchen?

A commercial kitchen is a functional space that meets a list of requirements set out by the health department. These requirements include key factors such as cleanliness and safe food handling. Licenses require annual renewal and the local health department inspect and license the kitchens. This is why the local health department is a good place to start when you are considering building your own commercial kitchen.

A commercial kitchen also needs commercial grade equipment, for instance, fridges and freezer units that comply with code requirements. The kitchen must have separate sinks for dishes, mops, hand washing and food preparation areas. 

The design of commercial kitchens is all about workflow. The positioning of appliances, preparation areas, storage areas etc. is decided based on workflow and efficient processes. There are fully kitted and licensed commercial kitchens that are available to rent or lease. This is a good alternative if budget or licensing requirements mean you cannot build a commercial kitchen in your home or garage. 

Cottage Food Operator

Some states now have a cottage food license that allows people to use their unlicensed home kitchen to produce certain foods for sale. This license comes with a lot of restrictions, for example, the types of food made and how the food is sold. There is also a limit on the gross sales allowed under a cottage food operation (in 2021, this increase to $78,000 in Minnesota). 

Cottage food producers need to meet a range of requirements including preparing and selling only non-potentially hazardous food (e.g. baked goods and jams) and labelling their food stating “These products are homemade and not subject to state inspection”.  If you sell more than $5,001 per year the cottage food registration includes a $50 fee. The cottage food license also states the person who makes the food must be the person who delivers it and you can only sell food from a private home, community event, farmers’ market or online, it cannot be wholesaled or shipped. 

This is a good option for small business home bakers or farms that produce their own jams but isn’t a sustainable option for people that want to create a wide range of foods and sell them further afield.

Design Your New Kitchen

Now you know you can turn your garage into a commercial kitchen and what the kitchen requires to meet the commercial standards, you can begin designing it to make the most of the space. When designing, take into consideration the storage, appliances and facilities you need to include. Remember the design needs to support the efficiency and workflow of a commercial kitchen. To help keep building and installation costs down, think about the location of existing plumbing and pipes.

Start Renovation and Building Work

Once you have designed your kitchen, and checked it suits the requirements of the department of health, you can begin the renovation work. We recommend getting quotes from various suppliers when looking for your new equipment etc. When comparing options don’t forget to check the warranty and shipping/ delivery information too.

The building work may feel like the main part of creating a commercial kitchen but you’ve already done the hard part in your licensing and regulation research. 

Apply For Your Food License

Once the flooring, equipment and everything else is installed you can apply for a commercial food license. The local health department will come and inspect your kitchen and, if it meets the requirements, you will receive a commercial food license. 

Once all of your licenses and permits are in place, you can make food and sell it to the public. Working from home has just got a whole lot better, congratulations on building your new commercial kitchen!
