Building a legal suite in my basement in Garrison Green - do I need two separate meters for electricity or just a subpanel?

For a legal basement suite in Calgary, you typically need just a subpanel, not separate electrical meters. The City of Calgary allows secondary suites to share the main electrical service as long as the electrical system is properly upgraded to handle the additional load.

Most basement suite conversions require upgrading your main electrical panel from 100 amp to 200 amp service to safely handle the increased electrical demand. The suite gets its own dedicated subpanel fed from the main panel, with separate circuits for lighting, outlets, appliances, and any electric heating or cooling systems. This subpanel must be properly labeled and accessible to both the homeowner and tenant.

Electrical permits and inspections are mandatory for all basement suite electrical work in Alberta. This work must be performed by a licensed electrician and inspected by certified Safety Codes Officers employed by the City of Calgary. The electrical rough-in inspection happens after wiring is complete but before drywall, and the final inspection occurs after all fixtures and devices are installed.

In Garrison Green, like all Calgary neighborhoods, your basement suite must meet Alberta Building Code requirements including proper fire separation between the suite and main house, separate entrance and egress, minimum ceiling heights of 1.95m (6'5"), and interconnected smoke alarm systems throughout both units. The electrical work is just one component of the overall suite development permit and building permit process.

Separate utility meters are possible but rarely required or cost-effective for basement suites. ENMAX can install separate meters if requested, but this involves significant additional costs ($2,000-$5,000+) and ongoing monthly service charges for each meter. Most landlords simply include utilities in the rent or use submetering systems to track tenant usage.

Your next steps: Apply for a development permit through the City of Calgary (calgaryplanningpermit.ca), then obtain building and electrical permits. The electrical contractor will determine the exact panel upgrade requirements based on your current service and the suite's electrical load calculations. Budget $3,000-$8,000 for the electrical work including panel upgrade, subpanel installation, new circuits, and permits.
