What Is the Standard Outlet and Light Switch Height?
Illuminate your home with ease
Highlights
Most electricians install light switches 48 inches from the floor.
ADA guidelines set the maximum height at 48 inches, although 40 inches is preferred to accommodate wheelchair users.
Outlets are typically installed 15 inches from the floor.
Always check local building codes and individual laws in your area.
Installing your electrical controls at the proper height is not only essential for your ergonomic comfort, but it’s also required for accessible use. While light switch height and outlet height is usually up to the homeowner’s discretion, there may be extra considerations based on local building codes and accommodations for individuals with disabilities. Here is everything you need to know about how high to install your light switches and outlets.
Standard Light Switch Height
The National Electrical Code (NEC) doesn’t specify a standard light switch height, but many local electricians will go with a height of 48 inches above the floor (measured from the floor to the bottom of the switch box).
Light switches located above kitchen counters are an exception to this rule—these will vary based on the distance between countertops and the bottom of your kitchen cabinets, but they’re often installed 4 inches above the countertop.
Standard Outlet Height
Similarly, the NEC doesn’t have specific requirements for the height of electrical outlets, but they are typically installed 15 inches above the floor. In some older homes, the outlets may only be 12 inches above the floor, but this may pose a problem for accessibility and not be up to ADA standards.
Countertop outlets in the kitchen are generally installed between 15 inches and 20 inches above the counters, which often ends up being about 42 inches from the floor. You must install ground fault circuit interrupter (GFCI) outlets in this area to prevent shock.
How to Measure Light Switch and Outlet Height
Whichever height you go for, it’s important to keep it consistent throughout your home. This will not only help your peace of mind, but also prevent any issues if you end up selling your home in the future.
Measuring tape is a basic tool that can help you achieve consistent light switch height. All you need to do is measure and mark the distance from the floor to the bottom of where the light switch or electrical outlet box will be. If you’re installing multiple light switches and outlets, consider constructing a story pole, which is a homemade measuring tool marked with the height you need. You can make one with a piece of lumber or any other straight, solid object you can find, like a broomstick.
If you’re measuring light switches across a long hallway for a three-way switch, or if you have multiple outlets in a single room, a laser level makes quick work of keeping your height measurement consistent. Simply measure and mark the location of the first switch, then use the laser guide to find the same height for additional switches.
ADA Compliance
The Americans with Disabilities Act (ADA) states that all frequently used outlets, switches, and controls must be in accessible locations. For light switch height, this means that the switch must be installed between 15 inches and 48 inches above the floor to accommodate individuals using wheelchairs. Although the standard 48 inches is the maximum height allowed for a light switch per ADA guidelines, it may be preferable to place them 40 inches above the floor for optimal accessibility.
If you’re accommodating a member of your household, it’s best to personalize the light switch height based on their specific needs and preferences. Otherwise, sticking to a maximum height of 48 inches from the floor will ensure compliance with ADA standards if you decide to sell your home.
Outlets follow the same rules and must be installed no lower than 15 inches above the ground to accommodate wheelchair users and other persons with limited mobility in the home.
Cost to Install New Light Switches and Outlets
The cost to install a new light switch is $60 to $300, with an average of $150. The overall price is affected by the type of switch, with dimmer and timer switches costing more than basic single switches.
Installing a new outlet costs between $130 and $300, depending on the type and location. These costs increase dramatically for outdoor outlets, which can cost over $1,000.
Replacing all the light switches and outlets in your home costs between $2,400 and $5,100, but it ultimately comes down to how many outlets and switches you have.
DIY vs. Hiring a Pro
Replacing an outlet or light switch is a simple task if you have basic DIY electrical experience and the right tools, particularly a voltage tester or multimeter to ensure no electricity is flowing through the wires. When you want to move the location of an outlet or switch, things become more complicated—though going up or down a few inches is typically easier than moving them a more substantial distance.
While some more experienced DIYers may be up to the challenge, most people should hire a pro to move an outlet or light switch. Remember that even a small mistake during these projects can result in electric shock or fire, so it’s best not to take any chances.
Frequently Asked Questions
ADA guidelines recommend placing light switches 40 inches above the floor rather than the more common 48 inches.
A light switch should be at least 2 inches from the edge of the trim of a door. The location of wall studs will often help determine where to put the light switch by your doorway, and in most cases, wall studs make it impossible to install the switch closer than 2 inches. When possible, try to keep the switch within arm’s length of the entryway.
