What is the ESA inspection process like for a new garage electrical installation in Ottawa?

The ESA (Electrical Safety Authority) inspection process for new garage electrical work in Ottawa involves two mandatory inspections: a rough-in inspection after the wiring is installed but before drywall goes up, and a final inspection once all devices, fixtures, and the electrical panel work are complete. Your licensed electrician will schedule both inspections through the ESA online portal or by phone, and you'll typically get inspection appointments within 2-3 business days in Ottawa.

The rough-in inspection happens after your electrician has run all the cables, installed outlet boxes, switch boxes, and any sub-panel or main panel modifications, but before the walls are closed up with drywall. The ESA inspector will verify that all wiring meets Ontario Electrical Safety Code requirements, check that GFCI protection is properly installed for all garage outlets (mandatory in garages), confirm proper wire sizing for circuits, and ensure any 240-volt circuits for heaters or EV chargers are correctly installed. They'll also verify that fire separation requirements are met if you're adding electrical to an attached garage - any penetrations through the fire-rated wall between garage and house must be properly sealed.

The final inspection occurs after all electrical work is complete, including light fixtures, outlets, switches, garage door opener wiring, and any heaters or EV chargers. The inspector will test GFCI outlets, verify proper grounding, check that all connections are secure, and ensure the electrical panel is properly labeled. For garage sub-panels, they'll confirm the feeder cable is correctly sized and protected. If you're installing a Level 2 EV charger, they'll verify it's properly connected and that the circuit can handle the load.

Critical timing consideration for Ottawa garages: If your garage construction spans winter months, coordinate the rough-in inspection before any heating system is installed and operating. ESA inspectors need safe access to all wiring, and a heated garage makes the inspection more comfortable for everyone involved. The inspection process typically adds 1-2 weeks to your electrical timeline, so factor this into your overall garage construction schedule.

Failed inspections mean re-scheduling and potential delays, so ensure your electrician is familiar with current ESA requirements. Common failure points include missing GFCI protection, improper fire separation sealing, undersized neutral conductors on 240-volt circuits, and inadequate panel labeling. When you pass both inspections, the ESA issues a Certificate of Inspection that's required for final building permit approval from the City of Ottawa.
