The kitchen is one of the most frequented spaces in a home. With all the time you may spend in it and appliances you need, it’s important that you have enough outlets to keep it functional and up to code.
Fortunately, the electrical code spells out how many countertop outlets a kitchen needs and where you need to put them.
The Required Distance Between Kitchen Countertop Outlets
The holy grail when considering how far to space your outlets in your kitchen is NEC 210.52(C). South Dakota contractors have been following the 2023 National Electrical Code since the state started enforcing it in November 2024.
According to this code, the maximum distance between two countertop outlets along a continuous wall line is 48 inches. It was written to ensure you can reach an outlet with ease no matter which counter space you’re working from. As such, it’s based on usable counter space. No point along your walls should be more than 24 inches from an outlet.
Counter spaces at least 12 inches wide are covered by this rule, so outlets must be positioned to meet the required spacing.
There are, however, some exceptions:
- Ranges and sinks interrupt usable countertop space, so the receptacle-spacing rules don’t apply to the space they occupy. The surrounding countertop may still need receptacles.
- The necessity of outlets behind a corner-mounted fixtures is usually determined by the 18-inch measurement discussed in NEC 210.52(C)(1). It helps determine which countertop wall space doesn’t require an outlet.
- Countertop sections narrower than 12 inches don’t require an outlet.
Mapping your usable counter space will make planning outlets significantly easier during the rough-in stage.
The Recommended Height of Kitchen Countertop Outlets
NEC 210.52(C)(3) covers the maximum height your outlet can sit, which is no higher than 20 inches above the countertop. The main thing you need to take into consideration when settling on the final height of your outlets is your backsplash. More specifically, how high you want it to go up the wall and the thickness of the tiles you plan to use.
| Situation | Concern |
|---|---|
| Thicker tiles or stone | If an outlet box is positioned too deeply into the wall, it won’t sit flush with your tiles. You may need to use box extenders or longer screws to rectify the issue. |
| Outlet is positioned within the tiles | Tiles need to be cut precisely to avoid gaps. |
| Homeowners change their mind about the height of the backsplash | The outlet may sit at an awkward angle which can mean needing to relocate the outlet. |
Make sure you’re happy with your tile design and how the position of your outlets might impact it.
Outlets on Islands vs Peninsulas
According to NEC 210.52(C)(2) islands and peninsulas no longer have to have outlets, but you do still need to have a provision to add one later. The exact provision is unstated, but the wiring method and termination need to meet local requirements. You can confirm the arrangement with your electrical contractor or local authority before your cabinets are installed to avoid any guesswork.
If you do install an outlet, the placement rules are the same as any counter outlet: on or above the surface and no more than 20 inches above, or in the counter with a listed assembly (NEC 210.52(C)(2)).
Outlet Problems You May Find in Old Kitchens
If you’ve purchased an older home, it may not have enough outlets to meet current requirements. The kitchen’s small-appliance branch circuits may also need to be upgraded. Kitchens generally require at least two 20-amp small-appliance branch circuits to supply the outlets covered by NEC 210.52(B)(1) and 210.11(C)(1).
Adding kitchen countertop outlets may involve three types of work:
- Installing a new circuit. This is mostly in the case that the old one is being overloaded by appliances it wasn’t designed for.
- New cables being fished through walls, ceilings, or the floor to reach new outlet locations.
- Patching drywall, plaster or tile once the new wiring is in.
Installing a plug strip can cut down on the wall work.
Once you start adding new wiring to your kitchen, you also need to check if the affected circuits need GFCI and AFCI protection. The 2023 NEC requires both in your kitchen, though the exact scope and exceptions differ. An electrician can help you determine which upgrades apply to your home.

FAQs
How many outlets does a kitchen counter need?
There isn’t a fixed number. Instead, you need to worry about spacing. Countertop sections that are at least 12 inches wide should always have an outlet positioned so that you’re never more than 24 inches away from an outlet at any given point along the wall line. That means every outlet should be within 4 feet of each other, or closer.
Do I need an electrician to add new kitchen outlets?
New kitchen outlets may require new wiring, circuit changes, GFCI protection, and inspection. A licensed electrical contractor can assess the existing circuitry and confirm local requirements before any work begins.
Can an outlet go above my backsplash?
Your wall outlet can’t be any higher than 20 inches from the counter, so you’ll need to work around that limit if you don’t want the outlets to interfere with your backsplash.
Why is my outlet not working?
If an outlet stops working, you need to check whether a GFCI device has tripped, or a circuit breaker has switched off. If neither of these is responsible for the issue, there may be a wiring fault or a problem with another outlet on the same circuit. Have an electrician investigate the problem.

Can countertop outlets go under the counter?
Not under the 2023 edition of the NEC. Countertop outlets must be on or above the counter, or in it with a listed assembly.
