Secondary suite electrical requirements in Victoria come down to four things: a panel arrangement that lets each unit reach its own breakers, a service big enough for both units, interconnected smoke and CO alarms, and a permit with inspection. New construction in the City of Victoria needs a separate panel and meter for each occupancy. Existing houses have more flexibility.
What does the City of Victoria require for panels and meters?
The City of Victoria's Electrical Inspections policy, "Service and Panels in Secondary Suites", reads Canadian Electrical Code rules 6-206(2)(b) and 26-400 as requiring immediate access to the overcurrent devices for each occupancy without entering the other occupancy. From that, the policy sets out:
- New construction: a separate panel and meter must be supplied for each occupancy, and all wiring must be supplied from the individual panels and may not supply loads in the other occupancy.
- Existing single-family dwelling converted to a suite: where the existing service is big enough to supply both occupancies (calculated using Rule 8-200(2)) and the panel sits in a common area, circuits for both occupancies may come from one panelboard. Where the panel sits inside one occupancy and the service is big enough, the circuits are separated and a second panel with a main breaker goes in the other occupancy. That second panel may have an owner-supplied revenue meter to show the second occupant's use.
- Service too small: the upgraded service must follow one of the two arrangements above.
- Recommendation: the City recommends that all secondary suites be supplied by a separately metered panel.
The policy document is dated August 18, 2011, so confirm with the City's electrical inspections section that it is still current for your address.
What does the Code say about a panel in the suite?
Technical Safety BC's Information Bulletin IB-EL 2023-03 (Revision 2, dated March 4, 2025) interprets Rule 26-602 of the 2024 BC Electrical Code. Its main points:
- A panelboard is required in every dwelling unit, except units created by subdividing a single dwelling that are not individually metered.
- The rule does not require separate metering. If the suite is not individually metered, a separate panelboard is not required by that rule.
- If the suite is individually metered (for example two meters in a duplex meter base), a separately fed panelboard must be located in each subdivision.
- Each panelboard supply must be capable of being disconnected without disconnecting any other dwelling unit.
- The bulletin works through location examples: if both panels are in one place, such as a garage or common entry, both parties need access to it.
The bulletin also notes that municipal requirements may vary and that installers should consult the local authority before work. That is why the City of Victoria can ask for more than the minimum the Code interpretation sets.
| Scenario | What the sources say |
|---|---|
| New build in the City of Victoria | Separate panel and meter for each occupancy |
| Existing house, panel in a common area, service big enough | One panelboard can serve both, per the City's policy |
| Existing house, panel inside one unit | Second panel with main breaker in the other unit |
| Suite individually metered | A separately fed panelboard in each subdivision (TSBC IB-EL 2023-03) |
| Service too small for both units | Service upgrade, then one of the arrangements above |
Does the service need to be upgraded?
Possibly. The City's policy and the Technical Safety BC bulletin both point to the Rule 8-200 load calculation for dwelling services. A suite adds a range or cooktop, lighting, receptacles, a water heater and heating to the house's total. In older Victoria homes with a 60 or 100 amp service, the calculation is where the conversation about a bigger service starts. See Is 60 amp service enough? and the panel upgrade cost guide. We do not publish a price here because the cost depends on the existing service, the panel location and the distance to the suite.
What smoke and CO alarm rules apply to a secondary suite?
Saanich's Secondary Suite Code Requirements handout summarizes the BC Building Code. Fire safety measures change the required fire separation between the suite and the rest of the house:
- With no additional measures, 45 minutes.
- One additional photo-electric smoke alarm in the suite and one in the primary residence, interconnected with each other, reduces it to 30 minutes.
- All smoke alarms in the house photo-electric and interconnected, so one alarm sounds all of them in both the suite and the main residence, reduces it to 15 minutes.
- Sprinklers throughout the building remove the requirement.
Carbon monoxide alarms are required in houses with an attached garage or a fuel-burning appliance such as a fireplace. They go inside or within 5 m of each bedroom, and where required in a house with a suite they must be interconnected in both units. Alarm layout is a building code question. Your building official and the municipality's handout are the source of truth, and the electrician wires what the plan calls for.
Do you need an electrical permit for a suite?
Yes, new circuits, panels and service changes are permitted electrical work. A Technical Safety BC licensed electrical contractor applies for the permit and the work is inspected. Technical Safety BC or your municipality issues it, depending on location. Saanich's handout says to contact Technical Safety BC for electrical requirements, while the City of Victoria runs its own electrical inspections. For how permits work, read homeowner versus contractor permits.
Planning a suite in an older house?
Check the wiring before you finish the suite. Knob and tube or aluminum branch circuits affect insurance and what a suite inspection will accept. Our posts on knob and tube wiring in Victoria homes and why breakers trip are a good place to start. If you also plan a detached unit, see garden suite electrical in Victoria.

Send us the address, the age of the house and where the panel is, and we will tell you which of the arrangements above applies. See our new electrical page or request a quote on the contact page. Confirm municipal requirements with the City of Victoria or your municipality, and Code questions with Technical Safety BC.
Frequently asked questions
Does a secondary suite need its own electrical panel in Victoria?
For new construction in the City of Victoria, yes: a separate panel and meter for each occupancy. For converted existing houses, one common panel can serve both units if the service is big enough and the panel is in a common area, otherwise a second panel is added in the other unit.
Does a secondary suite need its own meter?
The Code does not require separate metering for the suite in all cases, according to Technical Safety BC's IB-EL 2023-03, but the City of Victoria requires it for new construction and recommends it for all suites.
Do smoke alarms in a suite have to be interconnected?
Alarm interconnection decides the required fire separation. Saanich's handout lists interconnected photo-electric alarms in both units as a way to reduce the separation rating. CO alarms, where required, must be interconnected in both units.
Do I need an electrical permit for a secondary suite?
Yes. New circuits, panels and service work are permitted, inspected work done by a licensed electrical contractor. Technical Safety BC or your municipality issues the permit.
Do I need to upgrade my service to add a suite?
It depends on the Rule 8-200 load calculation for the whole house. Older 60 and 100 amp services are where upgrades most often come up.
