Do I need separate utilities for a secondary suite?

Yes, you'll need separate utilities for a secondary suite in Ottawa, but the specific requirements depend on your property type and local regulations. Most secondary suites require separate hydro metering, while water/sewer and gas can often remain on shared systems with proper sub-metering arrangements.

For electrical service, the Electrical Safety Authority (ESA) typically requires separate metering for secondary suites to ensure each unit can be billed independently. This means installing a second electrical panel and meter base, which requires an ESA permit and inspection. The work must be done by a licensed electrician, and Hydro Ottawa will need to approve the new service connection. Expect this electrical upgrade to cost between $3,000-$6,000 depending on your home's current electrical capacity and the distance from the main panel to the suite.

Water and sewer services can usually remain on a shared system since Ottawa bills based on the main water meter. However, many landlords choose to install sub-meters to track individual usage for billing purposes. These aren't required by the city but can help with tenant relations and cost management. Sub-metering systems typically cost $800-$1,500 to install.

For natural gas, Enbridge Gas allows shared service in most cases, but you may want separate shut-offs for each unit. If the suite has its own heating system, furnace, or gas appliances, proper isolation valves and separate controls are essential for safety and convenience. Any gas work requires a licensed TSSA technician and proper permits.

The Ontario Building Code requires that secondary suites have independent climate control, which often means separate heating and cooling systems. This doesn't necessarily require separate gas meters, but it does mean dedicated HVAC equipment for each unit. In Ottawa's climate, this is crucial for tenant comfort and energy efficiency.

When planning your secondary suite, factor in these utility upgrades early in your budget and timeline. The electrical work alone can add 2-3 weeks to your project due to permit processing and Hydro Ottawa coordination. It's also worth noting that some older Ottawa homes may need electrical service upgrades to handle the additional load of a second unit.
