DIY electrical work in Québec: what the law allows
Outlet, switch, breaker, light fixture: what the Régie du bâtiment and the CMEQ say, at home, at the cottage or in a condo.
In short
In Québec, work on an electrical installation must always be done by a contractor who holds the appropriate licence, even in your own home.
- The RBQ lets you renovate your single-family house yourself, except the electrical, gas and petroleum equipment.
- The rule is the same in a condo (private portion) and at the family cottage.
- According to the CMEQ, only master electricians may perform or have electrical work performed.
- The fine ranges from $5,000 to $200,888.

What the Régie du bâtiment says
On its page about work you can do yourself, the RBQ is clear: you don’t need a licence to build or renovate your single-family house, except for work that concerns an electrical installation, a gas installation or petroleum equipment. That work must be done by a contractor who holds the appropriate licence.
For electrical work, that licence includes subclass 16, Electrical contractor.
House, condo or cottage: same rule
| Where you do the work | What the RBQ says about electrical work |
|---|---|
| Your single-family house | Work reserved to a licensed contractor. |
| Your condo (private portion) | A licence is always required. |
| Your family cottage | A licence is always required. |
What the CMEQ says
The Corporation des maîtres électriciens du Québec sums it up this way: only master electricians may perform or have electrical work performed. Breaking the Master Electricians Act and the Building Act exposes you to a fine of $5,000 to $200,888.
To check a contractor’s licence before you sign, see our guide master electrician: role and how to check.
What about small jobs?
The RBQ page makes no exception for a light fixture, an outlet, a switch or a breaker: it talks about work on an electrical installation, without separating small jobs from big ones.
Redoing a grounding electrode, replacing an outlet or adding a GFCI is electrical work. So is replacing a breaker.
What doesn’t need an electrician: resetting a breaker that tripped, once the cause is found. Our guides on the circuit breaker and a breaker that keeps tripping explain what to do, and when to call.
A small job to do?

Without opening anything, you can measure the clearance in front of the panel and the height of the handles.
You can also locate the grounding wire leaving the panel, check whether the water service is metal or plastic, and count the two-prong outlets. The rest takes a master electrician.
Frequently asked questions
Can I replace an outlet myself in Québec?
No. Replacing an outlet is electrical work, and the Régie du bâtiment reserves that work to a licensed contractor, even in your own home.
Can I change a breaker myself?
No, for the same reason: it’s work on an electrical installation. Resetting it, yes, once the cause is found.
What about my condo or my cottage?
Same rule: the RBQ specifies that a licence is always required for an electrical installation, in a condo as at the family cottage.
What is the fine?
From $5,000 to $200,888, according to the CMEQ, for a person who breaks the Master Electricians Act and the Building Act.
How do I check that an electrician has a licence?
With their licence number, in the RBQ register; for electrical work, look for subclass 16. The details are in our guide on the master electrician.
