An Overview of Electrical Code Requirements Room by Room

When considering any projects that require electrical work, there are many reasons to call a professional from the get-go. First and foremost, you want to make sure nobody is injured during construction or during use when the project is completed. This is ensured by inspections and enforcement of electrical codes.

That leads us to another important reason to call a professional electrician at the beginning of any project requiring electrical work. A licensed electrician in your area, such as C&F Electrical, will know all the electrical code requirements in the Dallas-Fort Worth Metroplex, TX. By hiring a professional, you will be sure your project will pass inspection and will not need to be torn apart to fix electrical work that wasn’t done right the first time.

These electrical code requirements are mostly based on the National Electrical Code, which is updated every three years (the latest update was released in 2020). Most local codes follow this code, but a professional local electrician will know any differences that may exist. These requirements apply generally to all electrical projects, but there are specific regulations for individual rooms as well.

Here are some room-by-room requirements that you may be interested to know about when planning your commercial construction project.


Bathrooms have a lot of water and, therefore, have a lot of requirements around electrical work for safety reasons. Not only are there switched amenities like lights, fans and heaters to consider, but several appliances commonly used in bathrooms draw a lot of power, including hand dryers and other electrical accessories.

One requirement is that built-in heaters must have their own 20-amp circuit. Outside of that, a bathroom can be served by a single 20-amp circuit for the entire room as long as that circuit is not powering any other areas. Another requirement is that plugs in a bathroom must have ground fault circuit interrupter (GFCI) protection and at least one plug must be within 3 feet of the sink basin.


The kitchen is the powerhouse of commercial spaces like restaurants. It generally uses the greatest amount of electricity of all the rooms in the building—especially today with the increasing number of appliances that have become standard in modern kitchens, like large refrigerators, microwaves, ovens, dishwashers, garbage disposals, air fryers, powerful blenders, stand mixers and more.

For this reason, kitchens require at least two 20-amp circuits for plug-in appliances. Outlets must not be more than 4 feet apart, and any within 6 feet of a sink must be GFCI-protected. But there’s much more required for a kitchen than just power for wall outlets.

The oven/range needs its own dedicated 120/240-volt circuit, as do the refrigerator, microwave, dishwasher and garbage disposal. Lighting in the kitchen also needs to be on its own circuit of at least 15 amps.
