Code Changes That Affect Your Property

NEC updates, California amendments, and compliance deadlines

The National Electrical Code gets updated every three years — and California adopts it with its own amendments. What was code-compliant in 2020 might not pass inspection today. Here's what's changed recently and what it means for your property.

1 NEC 2023 — Key Changes

230.67 — Surge Protection

Surge protective devices (SPDs) are now required on all new service equipment and panel replacements. Whole-house surge protection is no longer optional — it's code.

210.8(A) — GFCI Expansion

GFCI protection now required on all 125V through 250V receptacles in garages, laundry areas, and kitchens — not just 125V. This is a significant expansion.

210.12(A) — AFCI Expansion

AFCI protection now required in dormitories, hotels, motels, and similar occupancies. Existing residential AFCI requirements remain but are more stringently enforced.

625.52 — EV Charger Load Management

New requirements for EV supply equipment load management systems, including monitoring and automatic load shedding provisions.

2 California-Specific Requirements (Title 24)

Solar-Ready Requirements (2019)

New single-family homes must include conduit and panel space for future solar installation. Minimum 225A panel with 20% spare breaker space.

EV-Ready Requirements (2022)

New multi-family and commercial parking must include EV-capable infrastructure — conduit, wire, and breaker space for Level 2 charging at 10% of spaces minimum.

Battery Storage Provisions

Fire-resistant barrier requirements for battery storage systems. Mandatory shutdown signaling for first responders.

Earthquake Shutoff Valves

Required on all natural gas lines serving generators in California. Automatic gas shutoff during seismic events.

Compliance Deadlines & Triggers

• Panel replacement triggers full code compliance — you can't swap a panel without bringing the entire service up to current NEC

• Service upgrades require Arc-Fault and Ground-Fault protection on all applicable circuits

• Commercial tenant improvements require Title 24 energy compliance documentation

• Generator installations require seismic anchoring and automatic gas shutoff per California amendments

• Adding any new 240V circuit (AC, EV charger, hot tub) requires evaluating existing AFCI/GFCI compliance

What Matters

Code changes are confusing, but non-compliance is expensive. We'll audit your property against current code and show you exactly what needs attention.
