Poly B replacement permits in Quebec City
What Quebec City actually publishes about permitting a residential repipe, verified August 6, 2026.
Is a permit required?
Not from the city, for a pure repipe: the harmonized planning bylaw exempts changing, renovating or replacing plumbing from the building permit requirement so long as rooftop equipment footprints don't change. Permits enter when the renovation goes beyond the plumbing itself.
Who can pull the permit
A hired contractor needs an RBQ plumbing licence and CMMTQ membership, which the city's own water-line program pages reiterate. Homeowner DIY on an owner-occupied single-family home is legal provincially, with the RBQ declaration still required.
Inspections
Through the RBQ regime for the plumbing; municipal inspection only where a broader permit applies.
Fees
No municipal fee for the exempt repipe case; the city hasn't published a fee schedule capture for adjacent permit cases, so confirm if your project goes beyond plumbing.
Timelines
Around 30 days for a first response where a permit does apply, longer in heritage areas.
Who administers it
Régie du bâtiment du Québec; Ville de Québec permits counter for broader renovations.
What Quebec City doesn’t publish
In keeping with this site’s rule of never guessing, these details were not verifiable from Quebec City’s published materials and should be confirmed directly with the municipality:
- ?Fee schedule for permit-triggering cases.
- ?Individual borough bylaw mirror-provisions assumed, not individually checked.
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 Quebec City city profile shows how much of the local housing stock sits in the Poly B era.
