The BC electrical code changes for 2024 took effect on March 4, 2025, when the 2024 Canadian Electrical Code (CSA C22.1-24, 26th edition) became the BC Electrical Code. Technical Safety BC says BC made no deviations from it this cycle. For homeowners, the changes that matter are EV charger load rules, outdoor receptacles, energy storage and pool bonding.
When did the 2024 BC Electrical Code take effect?
Technical Safety BC's information bulletin on the adoption says that, effective March 4, 2025, the Canadian Electrical Code, Part I, 26th Edition (CSA C22.1-24) is adopted as the BC Electrical Code. The same bulletin states there are no BC deviations from the Canadian Electrical Code this cycle, so the national text is the BC text.
Does it apply to work already permitted?
The transition rules turn on the date the permit was issued:
| Permit issued | Which edition applies |
|---|---|
| Before March 4, 2025 | The 2021 (25th) edition until the work is completed, by default |
| Before March 4, 2025, with a declaration | The 2024 edition, if the work finishes after March 4, 2025 and the licensed contractor declared on the application that it would be followed |
| After March 4, 2025 | The 2024 (26th) edition, without exception |
Sections of the two editions cannot be mixed. Today, October 2026, any new permit falls under the 2024 edition. As a general principle, code editions govern new installation work done under a permit. If you are unsure how a rule applies to existing wiring in your house, ask Technical Safety BC or your municipality.
Which 2024 code changes affect homes?
Technical Safety BC's article on the top 10 changes lists the following items that touch dwellings:
- EV charging loads (Section 8-202). New demand rules for electric vehicle supply equipment (EVSE) and electric vehicle energy management systems (EVEMS). This is the part of the Code that decides how a charger is counted when your service is sized. If you are weighing a charger, see our posts on EVEMS versus a panel upgrade and panel upgrades for an EV charger.
- Outdoor receptacles (Section 26-724). New rules requiring additional receptacles on the outside of dwelling units. Technical Safety BC's summary does not give the number or locations, so ask your electrician what your drawings will show.
- Energy storage systems (Section 64-100). New requirements for energy storage and renewable energy systems, which affects home batteries paired with solar. See backup power options.
- Pools and spas (Sections 68-058 and 68-072). Updated bonding requirements for electrical equipment and other conductive infrastructure around pools, and guidelines for locating the pool equipment disconnecting means.
The other changes on the list, such as equipment marking, shock and arc flash protection, gas piping bonding, overhead support spans, health care facilities and fibre optic cable, are mostly aimed at installers and non-residential settings.
What did the 2024 update change for suites and panels?
Technical Safety BC's Information Bulletin IB-EL 2023-03 on panelboards in secondary suites was revised on March 4, 2025 to provide guidance on the 2024 BC Electrical Code. It explains Rule 26-602: a panelboard is required in every dwelling unit, except for units created by subdividing a single dwelling that are not individually metered. See our post on secondary suite electrical requirements in Victoria for how the City of Victoria applies it.
Do I have to upgrade my existing wiring?
The sources above describe how the code applies to permitted installation work. They do not say that the 2024 edition forces upgrades to existing wiring in a home. What does happen is that when you renovate, add a circuit, install a charger or replace a panel, the new work is built and inspected to the current edition. If you are planning a renovation, the renovations page explains how we approach it, and older wiring issues are covered in our posts on knob and tube wiring in Victoria homes and Technical Safety BC electrical permits.
What should you do with this?
- If you are building or renovating, ask your electrician to confirm the permit will be issued under the 2024 edition and what changes for your plans.
- If you are adding an EV charger or battery, ask how the new demand and storage rules affect your service size.
- If you have a pool or spa, ask whether the updated bonding and disconnect requirements affect your installation.
