What are the New Afci and Gfci Requirements in the 2026 California Electrical Code?

The 2026 California Electrical Code introduces significant updates to safety standards, focusing on expanded protections for both fire prevention and shock hazards. These changes align with the latest national safety recommendations to better protect modern households.

Expanded AFCI Protection Requirements Arc-fault circuit interrupters (AFCI) are now mandatory for all living spaces inside the home. While previously restricted to specific areas, the 2026 code requires these breakers for all 120-volt, 15- and 20-amp branch circuits supplying:

• Bedrooms and hallways
• Living rooms and family rooms
• Kitchens and laundry rooms

These devices are essential because they detect dangerous wiring arcs that can overheat and cause electrical fires. For older homes, meeting these new standards often necessitates an Electric Panel Upgrade to accommodate the additional AFCI breakers.

Expanded GFCI Protection Requirements Ground-fault circuit interrupter (GFCI) requirements have been broadened to cover more moisture-prone areas to reduce the risk of electric shock. New mandates include:

• Kitchens: All 15- and 20-amp, 125-volt outlets, including the refrigerator receptacle and kitchen islands.
• Bathrooms: All outlets within the room must be protected, regardless of their distance from the sink.
• Garages and Outdoors: GFCI protection is required for all garage receptacles and outdoor outlets.

Mandatory Whole Home Surge Protection In addition to AFCI and GFCI updates, the code now mandates a listed Type 1 or Type 2 surge protective device (SPD) at the service entrance for all new constructions and significant renovations. This provides a comprehensive defense for your appliances and electronics against voltage spikes.
