Do secondary suites in Ottawa need separate utility meters and electrical panels?

Yes, secondary suites in Ottawa typically require separate electrical panels, but separate utility meters are not always mandatory - though they're highly recommended for practical reasons.

Electrical Requirements

Under the Ontario Building Code and Ottawa's zoning bylaws, secondary suites must have their own electrical panel to ensure proper load distribution and safety. This separate panel allows for independent circuit protection and makes it easier to isolate electrical issues. The electrical work must be performed by a licensed electrician and inspected by the Electrical Safety Authority (ESA) - this is not a DIY project.

The main electrical service to your home may need upgrading from the typical 100-amp service to 200-amp to handle the additional load. In Ottawa's older neighborhoods like the Glebe or Westboro, many homes still have 100-amp services that will require upgrading before adding a secondary suite.

Utility Meter Requirements

Separate utility meters are not legally required by the City of Ottawa, but they offer significant advantages. For electricity, you can request Hydro Ottawa install a second meter, which typically costs $1,000-2,000 including the meter base and connection work. This allows you to bill tenants directly for their electrical usage and provides clear accountability.

For gas, if your suite has separate gas appliances (furnace, water heater, stove), Enbridge Gas can install a second meter. This is particularly valuable in Ottawa's climate where heating costs can be $150-300+ monthly during winter.

Water Metering Considerations

Ottawa is transitioning to universal water metering, but most properties still have single water connections. Separate water meters for suites are rare due to the complexity of retrofitting existing plumbing systems. Most landlords include water costs in rent or use a percentage-based calculation.

Practical Benefits of Separate Meters

Beyond the convenience of separate billing, separate meters provide clear usage tracking which helps with tenant disputes and property management. They also make your property more attractive to potential tenants who prefer controlling their own utility costs.

Next Steps

When planning your secondary suite, discuss metering options during your electrical design phase. The electrical panel separation is mandatory and must be included in your building permit application.
