Quebec building code question

What are the Quebec building code requirements for residential renovations?

Residential renovations in Quebec must comply with the Quebec Construction Code (Code de construction du Québec) for structural, fire safety, plumbing, and electrical work, with permits required by the municipality and licensed contractors required for most regulated work.

Quebec has a distinct regulatory framework for building construction and renovation. The Quebec Construction Code (CCQ) is based on the NBC but includes Quebec-specific amendments. Residential renovations must comply with the CCQ for structural changes, fire separation, plumbing, and mechanical work. Quebec also requires licensed contractors (licence RBQ) for most construction and renovation work, and municipalities issue building permits with local bylaw requirements. The scope of required compliance depends on the extent of the renovation.

  • The Quebec Construction Code is based on the NBC but includes province-specific amendments.
  • Licensed contractors (licence RBQ) are required for most regulated construction and renovation work in Quebec.
