When undertaking construction projects, it's essential to be aware of your declaration obligations as per the Construction Code of Quebec. Whether you're a contractor, owner-builder, or building professional, this page will guide you through the declaration process.

Which Works Need to Be Declared?

Any construction project, whether it involves foundations, erection, renovation, modification, or even the demolition of a building or equipment intended for public use, must be declared. Before starting, it's crucial to consult the relevant municipality to determine if a construction permit is required.

Works Without a Construction Permit:

If your project doesn't require a construction permit, the responsibility of declaration falls on the contractor or the owner-builder. This declaration must be addressed to the Quebec Building Board (RBQ) no later than the 20th day of the month following the commencement of the works. For this purpose, it's recommended to use the RBQ's official form titled "Work Declaration: Construction Code - Building Chapter".

Works With a Construction Permit:

If your project requires a construction permit issued by your municipality, it's the municipality's responsibility to declare the works to the RBQ. Therefore, ensure you communicate effectively with municipal authorities to guarantee your project's compliance.


The work declaration is a crucial step in ensuring the safety and compliance of all construction projects in Quebec. By adhering to these guidelines, you contribute to upholding high standards for buildings and equipment intended for public use.
