Poly B replacement permits in St. John's
What St. John's actually publishes about permitting a residential repipe, verified August 6, 2026.
Is a permit required?
Yes, and St. John's is one of the only cities in Canada whose fee schedule names the repipe scenario directly: a plumbing renovation without replacing or adding fixtures is a listed permit item.
Who can pull the permit
Only licensed plumbing contractors can apply, and the city runs its own licensing: a plumbing contractor's licence and journeyman licence issued by the city itself. Homeowners cannot be issued a plumbing permit but remain responsible for making sure one exists.
Inspections
City inspections under the plumbing bylaw, with up to four included for a single-family home and a fee per additional inspection.
Fees
About $18.50 per fixture with a $42 minimum, and a flat $42 for a renovation with no fixture changes, the repipe case.
Timelines
No published processing timeline; confirm with the permits office.
Who administers it
City of St. John's permits office.

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 St. John's city profile shows how much of the local housing stock sits in the Poly B era.
