When it comes to laundry area GFCI and AFCI requirements, many electricians, inspectors, and homeowners wonder what the 2023 NEC brought to the table that’s different from 2020. Here’s the quick answer up front: there were no major changes to the laundry area GFCI and AFCI requirements between the 2020 and 2023 NEC cycles. The essential protections—ground-fault and arc-fault—remain in place and largely unchanged, with only minor language clarifications elsewhere in the code.

This post focuses on what changed for laundry areas between the 2020 and 2023 NEC.

Why Laundry Area GFCI and AFCI Requirements Still Trip People Up

Despite the code’s consistency, confusion persists—and for good reason. These are some of the most common pain points and questions encountered in the field:

• Do laundry areas require GFCI protection even if there’s no sink?
• What’s the difference between GFCI and AFCI requirements for laundry circuits?
• Does a hardwired washer or dryer still need protection?
• When does an upgrade or remodel trigger these requirements?
• How do local amendments or AHJ interpretations affect what’s required?

This post breaks down the actual code requirements, highlights where confusion comes from, and provides clear, actionable guidance for anyone looking to pass inspection—and get the job done safely.

2020 NEC: The Baseline Requirements

GFCI Protection – 210.8(A)(10):
Starting with the 2020 NEC, all 125-volt through 250-volt receptacles installed in laundry areas of dwelling units—supplied by single-phase branch circuits rated 150 volts or less to ground—require GFCI protection. The rule applies whether or not there’s a sink present and covers standard 120V washer outlets and 240V dryer outlets. “Laundry area” means any location with laundry equipment, not just rooms labeled “laundry.”

AFCI Protection – 210.12(A) Dwelling Units:
The 2020 code also requires AFCI protection for all 120-volt, single-phase, 15- and 20-amp branch circuits supplying outlets or receptacles in laundry areas. This includes not just receptacles, but also lighting and any device within the defined space. AFCI can be provided by a listed combination AFCI breaker, listed branch/feeder AFCI plus listed outlet device, or other approved methods listed in 210.12(A)(1)-(6).

For a complete, inspector-level breakdown of where AFCI protection is required and how it’s enforced in the field, see AFCI Protection Requirements Explained.

Extension Exception – Re-work/Remodels:
Exception: AFCI protection is not required where the extension of existing branch circuit conductors is not more than 1.8 meters (6 feet) and does not include any additional outlets or devices, other than splicing devices. This measurement does not include conductors inside an enclosure, cabinet, or junction box. Always check 210.12(D) for full details, and consult your local AHJ for any stricter requirements.

2023 NEC: What Actually Changed?

When reviewing the 2023 NEC, it becomes clear that the requirements for laundry area GFCI and AFCI protection remain fundamentally unchanged from the 2020 code:

• GFCI protection is still required for all 125-volt through 250-volt receptacles in laundry areas supplied by single-phase branch circuits rated 150 volts or less to ground. This covers both standard 120V and 240V laundry circuits—regardless of whether a sink is present.
• AFCI protection is still required for all branch circuits serving laundry areas—including all 120-volt, single-phase, 10-, 15-, and 20-amp branch circuits supplying outlets or receptacles in laundry rooms.
• Clarification in 210.8(D): The 2023 NEC now clarifies GFCI protection for specific appliances—including clothes dryers —by explicitly requiring protection on the branch circuit or outlet. This applies when supplied by single or three phase phase circuits rated 150V or less to ground, up to 60A. This closes previous loopholes for hardwired or cord-and-plug-connected dryers.
• Expanded GFCI elsewhere: The most notable GFCI changes in 2023 are broader expansions in kitchens and some commercial or common laundry areas, not in dwelling unit laundry rooms.

For the inspector, contractor, or DIYer, the “rules of the game” for a home laundry area stayed basically the same. Most confusion comes from how these rules apply to specific equipment or remodel situations—not from any major change in the code itself.

Understanding “Supplied by Single-Phase Branch Circuits ≤ 150V to Ground”

A phrase that causes a lot of head-scratching is “supplied by single-phase branch circuits rated 150 volts or less to ground.” Here’s what it means in real-world terms:

• 120V Circuits: Standard laundry receptacles in most North American homes are on 120V branch circuits (single-phase, one hot leg to ground = 120V). These always fall under the GFCI/AFCI requirement.
• 240V Circuits: A typical residential all electric dryer may be on a 240V circuit. In a standard single-phase panel, each hot leg to ground measures 120V (so each “side” – (A/B)) is 120V to ground, even though the total across the two legs is 240V).
• Why It Matters: Because both legs of a 240V single-phase branch circuit are each 120V to ground, most residential laundry circuits—including for 240V dryers—fall within the “≤ 150V to ground” language, making them subject to the GFCI rules where applicable.

If a circuit is a higher-voltage commercial installation where a leg measures more than 150V to ground (such as certain three-phase or high-leg delta systems), it may not fall under these requirements—but that is rare in typical residential homes.

Checklist: Laundry Area GFCI and AFCI Requirements

• GFCI protection is installed for every 125V through 250V, 15- and 20-amp receptacle in the laundry area (single-phase, 150V or less to ground).
• AFCI protection is provided for all 120V, single-phase, 10-, 15-, and 20-amp branch circuits supplying outlets or receptacles in the laundry area.
• Dryer and washer branch circuits or outlets are GFCI protected where required—including hardwired appliances—per 210.8(D) if supplied by single-or three phase circuits rated 150V or less to ground, up to 60A.
• All work complies with both the adopted code cycle, manufacturer, and any local amendments and/or local AHJ.

Key Questions About Laundry Area GFCI and AFCI Requirements (and Clear Answers)

Q: Do both GFCI and AFCI protection need to be provided?
A: Yes. Nearly all laundry area receptacles and circuits require both GFCI and AFCI protection. GFCI is required for 125V–250V receptacles on single-phase branch circuits rated 150V or less to ground. AFCI is required for all 120V, single-phase, 10-, 15-, and 20-amp branch circuits supplying outlets or receptacles in laundry areas. Most field installations use a dual function AFCI/GFCI device.

Q: What about a hardwired dryer or washer?
A: If the appliance is supplied by a single-phase branch circuit rated 150V or less to ground (the norm for residential setups), GFCI protection is required—not just for receptacles but for outlets and branch circuits per 210.8(D). This was clarified in the 2023 NEC to close previous loopholes for hardwired equipment.

Q: Are there exceptions or amendments?
A: Always check with your local Authority Having Jurisdiction (AHJ). Some states or municipalities may have amendments or additional requirements. For AFCI, a short extension (not more than 1.8 meters/6 feet, with no new outlets/devices) may be exempt—see 210.12(D) and always confirm with the AHJ.

Bottom Line For: Laundry Area GFCI and AFCI Requirements

From 2020 to 2023, the NEC’s requirements for laundry area GFCI and AFCI protection have not significantly changed. The intent remains to provide shock and fire protection for all circuits serving laundry areas, regardless of sinks, and to clarify that both plug-in and hardwired equipment may be subject to these rules.

To avoid headaches and red tags, follow the checklist above, stay up to date with your adopted code cycle, and consult your AHJ if there’s any uncertainty
