Poly B replacement permits in Nanaimo
What Nanaimo actually publishes about permitting a residential repipe, verified August 6, 2026.
Is a permit required?
Yes. Nanaimo requires a plumbing permit for plumbing changes and fixture installations not already covered by a building permit, which captures a standalone repipe. Confirm exact scope wording with the city when applying.
Who can pull the permit
Nanaimo is unusually explicit: a homeowner may do their own plumbing if they live at the property, depending on the complexity of the installation, and must submit an isometric drawing. If the drawing doesn't demonstrate command of the plumbing code, the city requires a certified plumber. A plumbing declaration form is due before the first inspection.
Inspections
Required, booked through the city's online inspection request; requests by 4 p.m. are carried out the next business day.
Fees
Minimum $40 plus $8 per fixture under the city's fees and charges bylaw, with an online fee calculator available. Confirm current amounts.
Timelines
Inspections run next business day; permit processing time isn't published.
Who administers it
City of Nanaimo Building Inspections, Community Development; online permit application and inspection portals.
What Nanaimo doesn’t publish

- ?Named inspection stages.
- ?Permit processing timeline.
How this fits the bigger job
The permit and inspection record is part of the documentation package your insurer will want after a repipe, alongside the completion certificate. The insurance chapter covers that package, and the cost guide covers what the whole job runs. The Nanaimo city profile shows how much of the local housing stock sits in the Poly B era.
