Poly B replacement permits in Winnipeg
What Winnipeg actually publishes about permitting a residential repipe, verified August 6, 2026.
Is a permit required?
Yes, with the clearest wording in the country: Winnipeg requires a plumbing permit whenever a plumbing system is constructed, extended, altered, renewed or repaired, and specifically when water supply lines in a building are replaced. Leak repairs and like-for-like fixture swaps are exempt.
Who can pull the permit
A licensed City of Winnipeg plumbing contractor, or the owner of a single-family home who lives there and does the work personally, subject to the city being satisfied the work will be done competently. Homeowners sign a declaration, and the permit is not transferable.
Inspections
Rough-in before anything is concealed, with drains, vents and water supply lines completely roughed in, then a final with all fixtures operational. Corrected defects are re-inspected within 30 days. Book online or through the Housing Inspection office.
Fees
Charged per drain and fixture under the city's fees and charges schedule; confirm current amounts with the city.
Timelines
No published processing timeline; confirm with the city.
Who administers it
Planning, Property & Development, Zoning & Permits Branch; applications through Permits Online.

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 Winnipeg city profile shows how much of the local housing stock sits in the Poly B era.
