What we verify
A municipal permit, electrical inspection and utility connection are separate approvals.
The City of Ottawa publishes building-permit requirements for solar collectors on low-rise residential buildings. The project must also satisfy ESA and Hydro Ottawa requirements before grid connection.
2
Keep electrical approval separate
The building permit does not replace electrical inspection or Hydro Ottawa’s distributed energy connection process.
3
Maintain one coordinated project record
Roof plans, module and racking data, structural details, electrical drawings and contractor information should agree.

Frequently asked questions
Frequently asked questions
Does every rooftop project need the same package?
No. Building type, system, structural conditions and scope affect the submission. Confirm with the City before work.
Who approves electrical work?
Electrical work must follow Ontario requirements and the Electrical Safety Authority process.
Can equipment be ordered before approvals?
That creates avoidable risk. Confirm design, permit, interconnection and program dependencies before irreversible orders.
