If you’re planning a kitchen remodel or building a new home in 2026, it’s important to know about relatively recent changes to the National Electrical Code (NEC) regarding the placement of electrical outlets on kitchen islands and peninsulas. These updates simplify the requirements but also change where and how outlets can be installed, especially removing common side-mounted outlets that many homeowners and designers have used for years.
Here’s what you need to know and why it matters for both safety and code compliance.
What Has Changed in the NEC?
In the 2023 edition of the NEC, the requirements for receptacle outlets serving kitchen island and peninsula countertops were significantly revised.
No More Mandatory Outlets Based on Size
Under previous versions of the NEC (such as the 2020 edition), kitchens with islands or peninsulas had to include at least one receptacle for every specific amount of countertop space – one for the first 9 square feet and another for each additional 18 square feet. That rule was intended to ensure appliances could be used conveniently without running cords long distances.
That size-based requirement has now been removed. Islands and peninsulas are not required to have an outlet by default in the 2023 NEC. However, if you do choose to install one, it must meet the updated placement rules.
Outlets on Kitchen Islands Are Now Optional, But Future Provision Is Required
The revised NEC language in Section 210.52(C)(2) states that if you decide not to install a receptacle on an island or peninsula, you must still provide a provision for future installation. That means roughing in a junction box, conduit, or other wiring access so an outlet can be added later without tearing up finished cabinets or counters.
This change gives homeowners and designers greater flexibility when planning kitchen layouts, but it also means you shouldn’t simply skip outlet planning altogether. Future needs should still be considered as part of a thoughtful electrical design.
Where Can You Install an Outlet If You Want One?
If you do want outlets on your island or peninsula the updated NEC still allows them, but only in specific locations:
Option 1: Above the Countertop/Work Surface
Receptacles can be mounted above the countertop or work surface, but no more than 20 inches above that surface. For islands without a backsplash or wall, there are creative options such as raised bars or ledges or vertical columns attached to the island. However, most homeowners (in our experience) opt for option 2…
Option 2: Within the Countertop Surface
You can use receptacle assemblies that are listed for countertop use, such as pop-up outlets built into the countertop that stay flush when not in use and are rated for kitchen environments (including moisture resistance).
What’s No Longer Allowed
A big shift in the 2023 code is that outlets mounted below the countertop on the side of an island or peninsula (the classic side-mounted cabinet receptacle in islands) are no longer permitted when they are intended to serve the countertop or work surface. This is a safety-driven change to avoid cords dangling in areas where people are working and moving around.
Why Did the NEC Change These Rules?
Data from safety organizations like the Consumer Product Safety Commission (CPSC) showed that cords plugged into side-mounted outlets on islands or peninsulas created hazards including trip risks, appliances being pulled off counters, and burn injuries, especially to children. By making outlets optional and restricting their placement to above or in the countertop, the NEC aims to reduce these cord-hanging hazards.
Practical Tips for Homeowners and Builders
- Plan for future: Even if you opt not to install an outlet now, rough in wiring or a junction box so you can add one later easily.
- Use listed pop-up outlets: If you want a sleek, modern look, pop-up outlets rated for countertop installations can meet code and keep cords out of the way.
- Avoid side-mounted outlets: Unless your jurisdiction still follows older NEC editions, placing receptacles below the countertop on the island face may not be code compliant.
- Consult an electrician early: Working with a licensed professional ensures your plans align with current local code requirements before permits are pulled.
