How do I know if my contractor is following building code?

Ensuring your contractor follows the Ontario Building Code (OBC) is crucial for safety, insurance coverage, and resale value. The most reliable way is to verify they pull proper permits and schedule mandatory inspections through the City of Toronto Building Division.

Permit verification is your first line of defense. Any structural, electrical, plumbing, or HVAC work requires permits in Toronto. You can verify permits online through toronto.ca/building or call 416-397-5330. A legitimate contractor will handle permit applications and provide you with permit numbers. If they suggest skipping permits to "save money," that's a major red flag - unpermitted work can void insurance, create legal liability, and cause problems when selling your home.

Mandatory inspections ensure code compliance. The City of Toronto requires specific inspections at different project stages - foundation inspection before backfilling, framing inspection before drywall, electrical rough-in, plumbing rough-in, and final inspection. Your contractor should coordinate these inspections and provide you with inspection reports. Failed inspections must be corrected before work continues.

Licensed trades are required for specialized work. Electrical work must be performed by ESA (Electrical Safety Authority) licensed electricians, and gas work requires TSSA (Technical Standards and Safety Authority) certified technicians. Ask to see current licenses and verify them directly with ESA or TSSA. In Toronto's older neighborhoods like Cabbagetown or The Annex, century homes often require specialized knowledge of heritage requirements and updated electrical systems.

Documentation and communication matter. Professional contractors maintain detailed records, provide written contracts specifying code compliance, and communicate inspection schedules. They should explain any code-related changes needed during the project and provide updated cost estimates for additional work required to meet current standards.

Warning signs include contractors who discourage permits, can't provide license numbers, refuse to allow inspections, or pressure you to pay large sums upfront. Quality contractors understand that following building code protects both you and them from liability issues.

Next steps: Before work begins, verify your contractor has pulled appropriate permits, confirm they're using licensed trades for electrical/gas work, and establish an inspection schedule. Keep all permit documentation and inspection reports for your records - you'll need them for insurance claims and future home sales.
