Demystifying Code Requirements for Safer Homes in 2025

When building a new home in 2025, one of the most important aspects to get right is electrical safety. Modern code requirements for outlets and circuit protection have evolved to keep up with changing technology and to reduce the risk of fires, shocks, and other electrical hazards. Two of the most crucial protection devices in new construction are GFCIs (Ground Fault Circuit Interrupters) and AFCIs (Arc Fault Circuit Interrupters)—but when and where are each required? And what’s the difference between GFCI and AFCI protection?

This guide will walk you through GFCI vs AFCI requirements for new construction, based on the latest NEC (National Electrical Code) updates for 2025, and offer actionable tips for homeowners, builders, and anyone planning new electrical work.

What Are GFCI and AFCI Devices?

What is a GFCI?

A GFCI (Ground Fault Circuit Interrupter) is a safety device designed to protect people from electric shock. It works by monitoring the flow of electricity in a circuit and shutting off power in milliseconds if it detects a ground fault (current flowing outside the intended path, such as through water or a person). GFCI outlets are typically identified by their “Test” and “Reset” buttons.

What is an AFCI?

An AFCI (Arc Fault Circuit Interrupter) protects against electrical fires caused by arc faults—tiny sparks that can occur when wires are damaged or connections become loose. AFCI breakers (and some outlets) sense dangerous arcing conditions and cut power before a fire can start.

Key Differences:

  • GFCI = Shock Protection
  • AFCI = Fire Protection

Tip: Both devices look similar but serve different purposes. Learn how to tell if an outlet is GFCI or AFCI below.

Why Are GFCI and AFCI Protection Required?

The evolution of the electrical safety code reflects advances in building technology and a better understanding of household hazards. GFCI and AFCI protection significantly reduce the risk of:

  • Electrical shock (GFCI)
  • Residential fires from arcing (AFCI)
  • Code violations during home inspections

These protections are now standard in new home wiring, helping builders and homeowners meet outlet safety compliance standards and pass electrical inspections.

GFCI Outlet Code Requirements 2025

NEC Code GFCI Requirements

The National Electrical Code (NEC) has steadily expanded the locations where GFCI outlets are required. As of the 2025 code update:

  • GFCI protection is required in:
    • Bathrooms
    • Kitchens (all countertop outlets)
    • Laundry rooms
    • Garages
    • Unfinished basements
    • Outdoor outlets
    • Utility rooms and crawl spaces
    • Wet bar sinks
    • Within 6 feet of any water source

More details: Read the full electrical code updates for 2025.

Additional GFCI Rules

  • All 125-volt through 250-volt receptacles in the areas above require GFCI.
  • Outlets for dishwashers, laundry equipment, and even some HVAC equipment must now be GFCI-protected.
  • Tamper-resistant GFCI outlets are required for child safety.

AFCI Breaker Code for New Homes

NEC Code AFCI Requirements

AFCI protection is now required for nearly all 120-volt, single-phase, 15- and 20-amp branch circuits supplying outlets and devices in:

  • Living rooms
  • Bedrooms
  • Family rooms
  • Dining rooms
  • Hallways
  • Closets
  • Sunrooms and similar spaces

AFCI protection is achieved by:

  • Installing AFCI breakers in the main electrical panel, or
  • Using AFCI outlets where allowed by code

2025 Updates

The 2025 NEC has clarified that combination-type AFCIs are generally required (detecting both parallel and series arcs), and some local codes may require dual function GFCI/AFCI breakers in high-risk areas.

See local code differences: RS Electrical—Electrical new construction homes and renovations.

Where Are AFCI Breakers Required?

AFCI protection is required in:

  • Bedrooms and sleeping areas
  • Living rooms, family rooms, and dens
  • Dining rooms and breakfast nooks
  • Hallways and closets
  • Home offices and libraries
  • Many other habitable rooms

Exceptions:
Kitchens, bathrooms, garages, and unfinished basements generally do not require AFCI (these areas prioritize GFCI), but always check your local code and inspection requirements.

Room/Area GFCI Required AFCI Required Both?
Kitchen Yes No In some locations*
Bathroom Yes No Rare
Laundry Room Yes No Rare
Garage Yes No Rare
Bedroom No Yes No
Living Room No Yes No
Dining Room No Yes No
Basement (unfinished) Yes No Rare
Basement (finished) Yes Yes Sometimes
Hallway No Yes No

*Some kitchens may require dual function breakers (AFCI/GFCI) if the local code has adopted the latest NEC changes.

Are GFCI and AFCI Both Required in Kitchens and Bathrooms?

Kitchens:

  • GFCI: Required for all countertop outlets, dishwashers, and sinks.
  • AFCI: Increasingly required by code for all outlets (except those solely serving large appliances).
  • Dual Function Breakers: Some new homes use dual GFCI/AFCI breakers for full compliance.

Bathrooms:

  • GFCI: Required for all outlets.
  • AFCI: Rarely required in bathrooms but check your local amendments.

Laundry Rooms:

  • GFCI: Required for all outlets.
  • AFCI: Not always required, but some codes include laundry areas for AFCI protection.

How to Tell if an Outlet is GFCI or AFCI

Identifying a GFCI Outlet:

  • Has “Test” and “Reset” buttons on the faceplate.
  • May have a small indicator light.
  • Often labeled “GFCI Protected Outlet.”

Identifying an AFCI Device:

  • Usually located in the electrical panel as a special circuit breaker labeled “AFCI.”
  • Some outlets can also be AFCI-protected, labeled accordingly.

Dual Function Outlets/Breakers:

  • Labeled as “GFCI/AFCI.”
  • May be in either the panel (breaker) or at the outlet.

Confused? RS Electrical’s home electrical inspection checklist can help you spot the difference.

Can You Use GFCI and AFCI on the Same Circuit?

Yes—And Sometimes You Must

Some circuits, especially in kitchens, laundry rooms, and finished basements, may require both GFCI and AFCI protection. This can be achieved by:

  • Using dual function breakers (GFCI/AFCI) in the panel.
  • Combining an AFCI breaker with a downstream GFCI outlet (must be wired correctly).

When to use GFCI vs AFCI outlets is determined by the room and the device being protected. Always check with your local inspector or a qualified electrician to avoid common electrical inspection failures GFCI AFCI.
