How do I handle utility metering for a Calgary basement suite?

Most Calgary basement suites share utilities with the main dwelling and handle cost-splitting through the lease agreement rather than installing separate meters. While separate metering is technically possible, the cost and complexity make it impractical for the majority of suite conversions, and the City of Calgary does not require separate utility meters for secondary suites.

Electricity is the utility most commonly considered for separate metering. Installing a separate electrical meter requires coordination with ENMAX (Calgary's electric utility), a separate electrical panel for the suite, and a second meter base on the exterior of the home. The cost for a separate electrical service runs $3,000–$6,000 including the panel, meter base, ENMAX connection fees, and electrician labour. Most homeowners find it simpler to include a flat monthly utility fee in the rent or to split the bill based on a percentage. Some landlords install a sub-meter (a monitoring device on the suite's electrical panel) that tracks usage without being an official billing meter — these cost $150–$400 installed and give both parties transparency.

Natural gas is extremely difficult and expensive to separate in an existing home. ATCO Gas (Calgary's gas provider) would need to install a separate gas line and meter, which involves exterior excavation and significant cost — typically $5,000–$10,000+. Since basement suites share the home's furnace or have a supplemental heating system tied into the main gas line, virtually all Calgary suite owners include gas in the rent.

Water in Calgary is metered by the City and billed to the property owner. There is no practical way to separately meter water for a basement suite, and the City does not offer secondary water accounts for the same property. Water costs are almost universally included in the rent for Calgary suites.

The most common approach among experienced Calgary landlords is to calculate average monthly utility costs over the previous year, add a reasonable buffer for increased usage with a tenant, and build that amount into the monthly rent. This avoids disputes over utility splitting and simplifies bookkeeping. For a typical Calgary basement suite, expect $150–$250 per month in additional utility costs (electricity, gas, water, sewer) above what you'd use without a tenant, depending on the suite's size and the tenant's habits. Calgary's long winters mean heating costs from October through April are the biggest variable — proper insulation in the suite reduces this significantly.

If you're building a new suite and anticipate wanting separate electrical metering, have your electrician install the separate panel and meter base during construction when the cost is lowest. Retrofitting later is always more expensive. Find experienced suite builders through the Calgary Construction Network who can advise on the best metering approach for your specific situation.
