Plumbing, electrical and HVAC permits
Electrical, gas, plumbing and mechanical work may need separate permits, sometimes from an authority other than the city.
Updated September 24, 2026
The short answer
Trade work can require separate electrical, gas, plumbing or mechanical approvals even when the building permit is not the main issue. The responsible authority changes by province and sometimes by municipality.
A municipal building permit does not automatically include electrical, gas or other trade authorization.
What to check first
- Which trades are involved
- Who issues each permit
- Licensed-contractor requirements
- Rough-in and final inspections
Check the rule in your city
Choose your municipality for the local permit rule, thresholds and official source.

If a permit is required

Inspections
Rough-in, pressure/test, service and final inspections vary by trade and authority.
