Receptacle Spacing Requirements Under the NEC

Under the National Electrical Code, receptacle spacing requirements in a home start with a single rule: in habitable rooms, no point along the floor line of any wall can be more than six feet from a receptacle. That translates to outlets spaced no more than 12 feet apart on the same wall. Kitchens, bathrooms, laundry areas, hallways, outdoor spaces, and garages each have their own tighter or more specific rules layered on top of that baseline, and the edition of the NEC your local jurisdiction enforces determines exactly which version applies to your project.

The 6-Foot Rule in Living Areas

NEC Section 210.52(A) is the source of what electricians call the “6-foot/12-foot rule.” It applies to kitchens, living rooms, bedrooms, dining rooms, dens, and similar habitable spaces. The reasoning behind it is practical: a standard appliance cord runs about six feet, so a lamp or small device placed anywhere along a wall should reach a receptacle without an extension cord.¹

Any wall segment two feet wide or more needs at least one receptacle. That minimum catches narrow strips between a door and a corner, and it applies to spaces measured around corners too, so alcoves and bump-outs can’t be skipped.¹

What Counts as a Wall

The NEC’s definition of wall space is broader than most homeowners expect. It includes fixed panels in exterior walls, such as a picture window that doesn’t open, and it includes freestanding dividers like bar-height counters or railings. Doorways, fireplaces, and fixed cabinets without countertops break a wall into separate segments, and each segment two feet or wider is measured on its own and needs its own outlet.²

Kitchen Countertop Spacing

Kitchens get a tighter rule because of constant small-appliance use. Under NEC Section 210.52(C), no point along the wall line above a countertop can be more than 24 inches from a receptacle. In practice, wall countertop outlets end up about four feet apart at most.³ Receptacles serving countertops must also be mounted no more than 20 inches above the countertop surface, which keeps cords from stretching across sinks or burners.

At least two dedicated 20-ampere small-appliance branch circuits must supply the countertop receptacles in kitchens, pantries, breakfast rooms, and dining rooms. Adjacent countertop receptacles have to be wired to different circuits, so running a toaster and a blender at the same time won’t trip a breaker.

Islands and Peninsulas

This is where the code shifted. Before the 2023 NEC, islands and peninsulas carried square-footage-based requirements: one receptacle for the first nine square feet of island, another for each additional 18 square feet, and peninsulas needed an outlet once they reached 24 inches by 12 inches. The 2023 edition removed those requirements entirely, and the 2026 NEC keeps that approach.⁴

Under the current code, no receptacle is technically required on an island or peninsula. If you choose not to install one, though, you must provide provisions for adding a receptacle later, such as rough-in wiring beneath the countertop. If you do install one, it must meet the spacing and mounting rules in 210.52(C)(3). Most electricians still recommend at least one outlet on any island with a usable work surface.⁴

Bathroom Receptacles

NEC Section 210.52(D) requires at least one receptacle within three feet of the outside edge of each sink basin in a bathroom. The outlet has to be on a wall or partition adjacent to the basin, on the countertop itself, or on the side or face of the basin cabinet. It cannot be mounted more than 12 inches below the top of the basin or countertop.⁵

Bathroom receptacles must be supplied by at least one dedicated 20-ampere branch circuit. If that circuit serves only a single bathroom, it can also supply lighting and the exhaust fan in that same bathroom. If it feeds receptacles in more than one bathroom, no other equipment can share it.

Laundry Area

Every dwelling unit needs at least one receptacle in the area designated for laundry equipment, under NEC Section 210.52(F), and that receptacle must sit within six feet of the intended appliance location.⁵

The laundry receptacle has to be fed by a dedicated 20-ampere, 120-volt branch circuit. That circuit can supply other receptacles within the laundry area, but it cannot feed lighting or any outlet in another room.

Hallways and Foyers

Hallways 10 feet or longer must have at least one receptacle. The length is measured along the centerline of the hallway without passing through any doorway, so a hallway that bends around a corner still counts as one continuous measurement if no door breaks it up.⁵

Foyers get their own treatment under NEC Section 210.52(I). A foyer larger than 60 square feet that isn’t part of a hallway needs a receptacle on each wall space three feet wide or more that isn’t broken by a doorway or a floor-to-ceiling window. Smaller foyers don’t trigger this requirement, though the general wall spacing rules may still apply if the foyer opens directly into a habitable room.

Outdoor Receptacles

NEC Section 210.52(E) requires one-family and two-family dwellings to have at least one outdoor receptacle at both the front and back of the house, for a minimum of two outdoor outlets. Each must be readily accessible from grade and installed no higher than six and a half feet above the finished ground level.⁶

Garages

Every vehicle bay in a garage with electric power needs at least one receptacle, whether the garage is attached or detached. The outlet must be mounted no higher than five and a half feet above the floor. The branch circuit that feeds a garage receptacle cannot serve outlets outside the garage.⁷ That dedicated-circuit approach keeps power tools and EV chargers from affecting circuits in the living space.

Check Which NEC Edition Your Jurisdiction Uses

The NEC is a model code published by the National Fire Protection Association. It doesn’t automatically become law anywhere. Each state, county, or municipality adopts it formally, often with local amendments, so the edition and exact rules enforced in your area depend on your local authority having jurisdiction. Some places still enforce the 2020 or 2017 edition, which matters because island and peninsula requirements changed substantially in 2023. Before starting any receptacle project, confirm with your building department which NEC edition applies and whether any local amendments change the national rules.⁸
