Adopted by decree on January 27, 2021, the amendments to Chapter III, Plumbing, of the Construction Code have been in force since March 27, 2021. This chapter incorporates the National Plumbing Code (NPC) of Canada 2015, with Québec amendments . It replaces the previous version, which had been in effect since April 2014. Any new plumbing installation carried out after September 27, 2021 must comply with the requirements set out in this Chapter.
Note that, as of March 27, 2021, a six-month transition period allows for the use of either the 2010 or new 2015 edition of Chapter III, Plumbing.
To help plumbing contractors, plumbers and others in the industry update their knowledge, the RBQ recommends that they consult the Main Changes to the Quebec Construction Code, Chapter III – Plumbing [Fr] – PDF (5,0 MB)
It is important to note that this document does not cover all changes, but focuses on those likely to have a significant impact on plumbing installation work. In addition, it provides a refresher on certain articles in the Code that are relatively hard to understand.
It also recaps the plumbing requirements included in the new regulation on dwelling adaptability and the regulation on energy efficiency of buildings.
Please note that the relatively minor changes that are not discussed in this document must also be applied.
The Régie du bâtiment du Québec (RBQ) wishes to remind all plumbing contractors, professionals involved in designing and carrying out plumbing installation work, and manufacturers and distributors of plumbing products, that they must comply with the new requirements in effect.
Amendments introduced at the national level, as well as those applicable to the province of Québec, have been adopted by consensus by representatives of the various groups involved. The new regulation is consistent with the process of updating codes or standards in effect in Quebec, in view of harmonizing, whenever possible, the regulatory framework between provinces. The new regulation seeks primarily to improve the level of health, safety and protection provided by a building’s plumbing installations and adapt these installations to certain technological changes.
