What inspections are required during a bathroom renovation in BC?

Bathroom renovations in BC typically require plumbing and electrical inspections by Technical Safety BC (TSBC), plus a building permit inspection if structural changes are involved. The specific inspections depend on the scope of work, but most bathroom renos trigger at least one inspection requirement.

For a typical bathroom renovation involving new fixtures, lighting, or ventilation, you'll need plumbing inspections at two stages. The rough-in inspection occurs after new plumbing lines are installed but before walls are closed up — this covers new water supply lines, drain connections, and rough plumbing for toilets, sinks, tubs, or showers. The final plumbing inspection happens after fixtures are installed and connected, ensuring everything functions properly and meets BC Plumbing Code requirements. All plumbing work beyond simple fixture swaps must be done by a licensed plumber registered with Technical Safety BC.

Electrical inspections are required if you're adding new circuits, outlets, lighting, or ventilation fans. Like plumbing, electrical work requires both rough-in and final inspections by TSBC. The rough-in inspection covers new wiring, outlet boxes, and switch locations before drywall goes up. The final inspection ensures all connections are proper, GFCI protection is installed where required, and the work meets BC Electrical Code standards. Only licensed electrical contractors registered with TSBC can perform this work — homeowners cannot do their own electrical work in BC.

If your renovation involves structural changes like removing walls, enlarging windows, or modifying floor joists, you'll need a building permit from your municipality and additional inspections. Vancouver requires building permits for bathroom renovations that involve structural changes, plumbing relocations, or adding square footage. The building inspector will check framing, vapor barriers, insulation, and ensure the work complies with BC Building Code 2024 requirements. Other Metro Vancouver municipalities have similar requirements but specific thresholds vary.

Ventilation requirements are particularly important in BC's wet climate. All bathrooms must have either an operable window or mechanical ventilation capable of 50 CFM (cubic feet per minute). If you're installing a new exhaust fan, the electrical work requires TSBC inspection, and the ductwork must terminate outside — never into an attic or crawl space.

Inspection scheduling typically takes 24-48 hours notice through TSBC's online portal or by phone. Inspections cost approximately $75-$150 each depending on the type. Failed inspections require corrections and re-inspection fees. Most contractors handle inspection scheduling as part of their service, but confirm this upfront.

Before starting work, check if your project needs a building permit by contacting your municipal building department. In Vancouver, call 311 or visit vancouver.ca/building-permits. For strata properties, you'll also need written approval from your strata council before any renovation work begins, plus proof of contractor insurance and often a damage deposit.

The key is planning inspections into your timeline — expect 1-2 days between inspection scheduling and the actual visit, and never close up walls or install fixtures before required inspections are complete and approved.
