Kitchen Electrical Code in Washington: Circuits, Outlets, GFCI and AFCI

A kitchen carries more electrical rules than any other room in the house, and most of them come into play the moment a remodel adds or moves a circuit. This page sets out what the adopted code asks for, with the section number behind each figure, and says plainly where a number could not be confirmed.

One caution about sources. The National Electrical Code (NEC) is published by the National Fire Protection Association and is not free to read online. The NEC figures below were taken from published training summaries of the 2023 text, and the Washington amendments from the Washington Administrative Code itself. Your electrician and the inspector work from the code book, and their reading governs.

The edition in force as of October 2026

Washington adopts the 2023 edition of the National Electrical Code in WAC 296-46B-010, effective 1 April 2024, and adds its own amendments in chapter 296-46B WAC. The City of Vancouver lists the same edition: "2023 NEC, National Electrical Code, effective 04/01/2024".

A change is scheduled. Under a rule filed 18 November 2025 (WSR 25-23-069), the 2026 edition of the NEC is adopted effective 31 December 2026 and replaces the 2023 edition. Adopted standards apply by electrical permit issue date, so the date your permit is issued decides which edition your kitchen is inspected under, not the date the work starts.

What a remodel triggers and what can stay

Existing lawful wiring does not have to be upgraded just because the kitchen is being remodeled. WAC 296-46B-010(14) says installations that do not meet the current rules may continue "without change", and that additions, alterations, modifications or repairs to the electrical system must conform to the current requirements.

In practice that draws a clear line:

• New circuits and receptacles must meet the 2023 NEC in full.
• Extended or modified circuits pick up arc-fault protection. Where 15-amp or 20-amp, 120-volt branch-circuit wiring in a kitchen is extended, modified or replaced, it must be AFCI protected by an AFCI breaker or by an AFCI receptacle at the first receptacle outlet of the existing circuit (NEC 210.12(E)). The exception is an extension of less than 6 feet that adds no outlets or devices.
• Untouched circuits may remain as they are.

A full gut usually opens every wall, so most kitchens at that remodel level end up rewired to the current code as a practical matter.

Small-appliance circuits

The receptacles that serve the kitchen are fed differently from the rest of the house. Under NEC 210.52(B)(1) and 210.11(C)(1):

• Wall, floor and countertop receptacles in the kitchen, pantry, breakfast room and dining room, and the refrigerator receptacle, must be supplied by two or more 20-amp, 120-volt small-appliance branch circuits.
• Countertop receptacles must be fed by no fewer than two of those circuits (210.52(B)(3)).
• Those circuits may not supply lighting, or receptacles outside those rooms (210.52(B)(2)).
• A refrigerator may instead sit on its own individual circuit of 15 amps or larger (210.52(B)(1), Exception 2).

Countertop receptacles: spacing and height

The 24-inch rule is why a remodeled kitchen has a receptacle roughly every 4 feet along the backsplash. Plan their positions with the tile layout, because they are set before drywall. The backsplash page covers how to keep them from fighting the pattern.

Islands and peninsulas: Washington differs from the national code

The 2023 NEC stopped requiring a receptacle at an island or peninsula. If one is installed, it must follow 210.52(C)(3): on or above the countertop, or a listed in-counter assembly, and not on the side of the cabinet below the counter. The national text then says that where none is installed, provisions must be made for adding one later.

Washington removed that last part. WAC 296-46B-210(8) reads: "If receptacle outlets are not installed to serve an island or peninsular countertop or work surface, no future provisions to do so are required." So in Washington today an island receptacle is optional, and if you want one it goes on or in the counter. Many national articles still describe the future-provision rule, which does not apply here. See kitchen islands for how this affects island design.

GFCI protection

Ground-fault protection now covers nearly every kitchen outlet:

• All kitchen receptacles. NEC 210.8(A)(6) requires GFCI protection for receptacles in dwelling unit kitchens. The 2023 edition deleted the older "serving the countertop" limit, so range, refrigerator, disposal and microwave receptacles are included.
• Near sinks. Receptacles within 6 feet of the top inside edge of a sink bowl require GFCI (210.8(A)).
• Named appliances, plugged in or hardwired. The outlet supplying a dishwasher, electric range, wall-mounted oven, counter-mounted cooking unit or microwave oven requires GFCI (210.8(D)).
• Access. The GFCI device must be in a readily accessible location (210.8), which rules out burying it behind a built-in appliance.

No Washington amendment relaxing kitchen GFCI was found in WAC 296-46B-210. Proposed national interim amendments that would exempt some ranges, ovens and microwaves exist, but their status in Washington was not confirmed, so ask your electrician how the inspector is treating those appliances.

AFCI protection

NEC 210.12(B)(1) requires arc-fault protection for 15-amp and 20-amp, 120-volt branch circuits supplying outlets or devices in dwelling kitchens. A new 120-volt kitchen circuit therefore has to satisfy both the AFCI and the GFCI requirement. How that is done (which breaker or device) is your electrician's call.

Dedicated circuits: what is confirmed and what is not

One dedicated-circuit rule was confirmed for this guide: a cord-and-plug connected range hood, or an over-the-range microwave listed as a range hood, must be supplied by an individual branch circuit (NEC 422.16(B)(4)), and a hardwired hood may not be on a small-appliance circuit.

This is one reason appliance choices come early. An induction range, a second oven or a larger hood can change the panel load, and choosing between gas, electric and induction is partly an electrical decision.

Lighting

Most of what the state asks of kitchen lighting sits in the energy code, not the NEC. New lighting that is part of an alteration must use high-efficacy sources under the Washington State Energy Code (R503.1.4 and R404.1). The kitchen lighting page covers that, along with layout and controls.

How this is handled on a project

Electrical work in a kitchen remodel is drawn into the plan, permitted, roughed in, inspected with the walls open, and inspected again at final. The inspections page walks through that sequence. JDI Construction handles permits and project management for its clients, and the electrical layout is part of the itemized plan.
