Poly B replacement permits in Saint John
What Saint John actually publishes about permitting a residential repipe, verified August 6, 2026.
Is a permit required?
Yes. Saint John's plumbing bylaw requires a permit for installation, extension, alteration, renewal or repair of plumbing systems, which squarely covers a repipe.
Who can pull the permit
The application must be submitted by the licensed plumbing contractor through the city's One Stop Development Shop. Whether the provincial homeowner's permit applies inside the city isn't published; confirm with the city.
Inspections
The city's plumbing inspector must inspect before anything is covered; covered work can be ordered uncovered at the owner's cost.
Fees
Current amounts aren't published on the city's pages; confirm with the One Stop Development Shop.
Timelines
No published processing timeline; confirm with the city.
Who administers it
City of Saint John, One Stop Development Shop.
What Saint John doesn’t publish
In keeping with this site’s rule of never guessing, these details were not verifiable from Saint John’s published materials and should be confirmed directly with the municipality:
- ?Current fee amounts.
- ?Itemized inspection stages.
- ?Homeowner permit availability.
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 Saint John city profile shows how much of the local housing stock sits in the Poly B era.
