The question we get asked first on almost every suite job is about the meter. Owners want to know whether they can put the tenant on their own BC Hydro account, and they usually assume the answer is yes because that is how it works in a duplex.
It is a fair question with a clearer answer than most people expect, and the answer changes what the rest of the electrical scope looks like.
Do You Need a Separate Meter?
No, not under the electrical code.
Technical Safety BC published an information bulletin on panelboards in secondary suites that addresses this directly. Their position on the relevant rule is that it does not require separate metering, and that if the installer chooses not to meter the suite individually, no separate panelboard is required either.
That is worth reading twice, because the two things are linked. The separate panel requirement follows from the metering decision, not the other way round.
Local authorities can add requirements on top, so confirm it per municipality. But the default position in BC is that a legal secondary suite runs on one service, one meter and, if you want it, one panel.
So Should You Meter It Separately Anyway?
Most owners we work with decide not to, once they see what it involves.
A second revenue meter means a second service entrance, a second panel, and separating every circuit so nothing crosses between units. In an existing home that is not a small job, and the utility side carries its own cost and timeline.
The common alternative is including electricity in the rent, which is what most Metro Vancouver suite landlords do. The other option is a private sub-meter installed between the main panel and the suite feed, read manually and billed by the landlord. It is a legitimate arrangement and we install them, but understand what it is: a measuring device for your own accounting, not a BC Hydro account in the tenant’s name.
If you are building new, or already opening the whole house, that shifts. Separating services during construction is far cheaper than retrofitting later. Raise it during design, not after framing.
What the Panel Actually Needs
Whether or not you add a second panel, the existing service has to be able to carry a second dwelling unit. That is not a judgement call, it is a load calculation, and it is the first thing we do on a suite job.
The suite adds a kitchen, usually a laundry, its own heating, and in most cases its own hot water. On a 1970s home still running a 60 or 100 amp service, that arithmetic often does not work, and the honest answer is a panel upgrade before anything else happens.
Two things that push a marginal calculation over the line, and both come up constantly:
- An EV charger. If there is one now, or one planned, it belongs in the calculation from the start. Adding a suite and a charger to the same service is where we most often end up recommending a service increase. Our guide to EV charger installation covers the capacity side of that.
- Electric heat in the suite. Baseboards in a basement suite draw more than owners expect, particularly if the space was never heated properly before.
We run the calculation before quoting rather than after. A suite project that discovers it needs a service upgrade in week three is a different budget from the one that was approved.
The Alarm Decision That Changes Your Construction Cost
This is the part almost nobody explains properly, and it is where a few hundred dollars of electrical work saves thousands in construction.
Under Part 9 of the BC Building Code, the fire-resistance rating required between the suite and the main dwelling is not a fixed number. It moves depending on the smoke alarm arrangement you install.
Put in photoelectric alarms, hardwired with battery backup, interconnected across both units and the common spaces, and the required separation drops to the lower rating. Do not, and you build to the higher one.
Read that as a builder would. The difference between those two ratings is a materially different drywall, sealing and firestopping scope across every ceiling and every penetration between the two units. Upgrading the alarm system is the cheaper side of that trade by a wide margin.
The details that matter:
- Photoelectric type, not ionization. The code is specific about this in a house with a secondary suite.
- A permanent electrical connection for each smoke alarm. Wireless interconnection between units is generally accepted where running cable is impractical, but wireless interconnect is not a substitute for wired power.
- Interconnection across both dwelling units and the common spaces, so one alarm sounds them all.
- Carbon monoxide alarms where there is a fuel-burning appliance or an attached garage, also interconnected. CO alarms do not require the permanent electrical connection that smoke alarms do.
Bring this up with your builder at design stage, before the separation assembly is specified. After the drywall is priced, the saving is gone.
Planning a suite and not sure what your service will carry?
We run the load calculation, tell you whether the existing service is enough, and give you the electrical scope in writing before you commit to a build schedule. It is the cheapest hour of the whole project and it is the one that prevents the expensive surprise.

Dedicated Circuits, and What You Cannot Do
The suite needs its own circuits. You cannot extend the upstairs kitchen circuit down to the suite kitchen and call it finished, and an inspector will not accept it.
In practice that means dedicated circuits for the suite kitchen, for laundry if there is one, and appropriate protection throughout. It also means the suite’s circuits should be identifiable, which is one of the practical arguments for a subpanel even when the code does not require one: a tenant tripping a breaker should not need access to the owner’s panel to reset it.
A subpanel in the suite is often the right call for reasons that have nothing to do with metering. See our electrical installation and wiring pages.
What About the Existing Wiring?
If the house is older, the suite conversion is usually when the condition of the existing wiring stops being a background concern.
Knob-and-tube in the walls you are about to open, or aluminum branch wiring in the circuits you are about to extend, both have to be dealt with. Insurers have their own view on this that is often stricter than the code’s. We have written separately about knob-and-tube and insurance and about aluminum wiring risk, and both are worth reading before you start a suite in a pre-1980 home.
If you are not sure what is in your walls, an electrical inspection answers it before the budget is set rather than after.
Permits: Who Issues Them
Electrical permits in BC come from Technical Safety BC, with one significant exception. The City of Vancouver issues its own electrical permits rather than going through the province.
That catches people out regularly, including contractors from outside the city. If your suite is in Vancouver, the electrical permit path is different from the one in Burnaby or Coquitlam, and we handle the application either way.
Suite electrical work is also not realistically homeowner-permit territory. Whatever the general rules say about owner permits, a load calculation, a rated separation and an interconnected alarm system across two dwelling units is work an inspector expects from a licensed contractor.
Vancouver and Burnaby
Every municipality in Metro Vancouver handles suites slightly differently, and two are worth calling out because most of our suite work sits in them.
Vancouver has allowed secondary suites in every single-family house since 2004, and the housing stock reflects it. A large share of the suites we wire are in Vancouver Specials and older East Side homes, many of which are still on original 60 or 100 amp services. The City’s own electrical permit process applies. See our Vancouver electrician page, or panel upgrades in Vancouver if the service is the constraint.
Burnaby suites tend to be in post-war and 1970s homes across the south slope and Metrotown area, and the pattern is similar: the panel is usually the first thing that has to change. Our Burnaby electrician and Burnaby panel upgrade pages cover what we do there.
For suites that form part of a larger project, our renovation electrical services page covers how the electrical scope fits with the rest of the build.
Frequently Asked Questions
Is a separate electrical meter required for a legal suite in BC?
Not by the electrical code. Technical Safety BC’s guidance is that separate metering is not required, and that if the suite is not individually metered, a separate panelboard is not required either. Local authorities can add requirements, so confirm with your municipality.
Do I need a second panel?
Not necessarily. It follows from the metering decision rather than being a standalone requirement. That said, a subpanel in the suite is often worth doing anyway, so a tenant can reset their own breaker without needing access to your panel.
Will my existing service handle a suite?
A load calculation answers it. Older homes on 60 or 100 amp services frequently cannot, particularly once an EV charger or electric heat in the suite is added. We run the calculation before quoting.
What smoke alarms does a suite need?
Photoelectric, hardwired with battery backup, and interconnected across both units and the common spaces so one alarm sounds them all. Wireless interconnect is generally accepted where cabling is impractical, but it does not replace the wired power connection.
Can I just extend the existing circuits into the suite?
No. The suite needs dedicated circuits, particularly for the kitchen and laundry. Tapping an existing kitchen circuit will not pass inspection.
Who issues the electrical permit?
Technical Safety BC across most of the province. The City of Vancouver issues its own. We pull whichever applies as part of the job.
Can I do the electrical myself?
In practice, no. A load calculation, a rated fire separation and an interconnected alarm system across two dwelling units is work inspectors expect from a licensed electrical contractor.
Planning a Suite?
Get the load calculation done before the build schedule is set. It is the one number that decides whether the electrical side of your suite is straightforward or whether it starts with a service upgrade, and knowing it early is worth more than any other hour on the project.
