If you do the work on your buildings, equipment or facilities

You own installations, pieces of equipment or buildings that are not intended for your personal use or your family’s, like a duplex, an apartment building, a restaurant or a garage? If you plan on doing some work, make sure you have the right to do so.

Indeed, there are works that have to be done by a licence holder. If that’s your case, you must either hire a licensed contractor or obtain an owner-builder licence for yourself.

Work that you can’t do without a licence

A licence is always mandatory to carry out work on the following installations:

  • electrical installations
  • installations intended to use, store or distribute gas
  • petroleum equipment installations.

In addition, you must hold a licence to carry out the work included in the Schedule II of the List of licence subclasses – PDF (109 KB) or hire a contractor to do so, except if the works are estimated at less than $20,000.

Do you need a permit?

Ask your municipality to know whether you need a construction permit.

If you hire a licensed contractor

To have your work carried out, you may hire a general or specialized contractor holding the required licence subclasses.

However, if there are many types of work to have carried out and you want several contractors specialized in different fields to perform them, you need an owner-builder licence to coordinate the work.

Consult Choose a licenced contractor.
