If you are planning to carry out interior renovations, be aware that some work may require a permit from your municipality.. And no, it’s not just a formality! The permit ensures that renovations comply with the safety, construction, and zoning standards of the city or neighborhood where you live.
Before getting out your tools or calling in a contractor, take the time to understand when a permit is required, how to apply for one, and what you need to plan for to avoid unpleasant surprises.
What types of work require a permit?
Good news! Small projects such as repainting, installing new flooring, or replacing kitchen cabinets usually do not require any permit.
However, as soon as your renovation:
- affect the structure of the building (e.g., removing a wall),
- change the interior layout (e.g., convert two rooms into one),
- affect the plumbing or electrical system (e.g., moving a bathroom),
- or change the use of a space (e.g., finishing a basement to turn it into a bachelor),
. . . It is highly likely that you will have to obtain a permit from your borough or city.
How do I know if a permit is required for my project?
Each city has its own rules, so it’s best to check right from the start. We recommend contacting your borough as soon as you begin planning your project. In large cities such as Montreal, you can even find a practical guide directly on their website.
Tip: It’s better to ask the question now than to have to correct or start over later.
How do I obtain a renovation permit?
Here is what you need to plan for:
1. Gather the necessary documents
Depending on the scope of the work, you may be asked:
- A description of the work to be carried out
- Plans (made by a technologist or architect, as appropriate)
- A cost estimate
- Proof that you are the owner
2. Submit the request
Depending on your city, you can do this online or in person. Generally, there is a fee for applying for a permit.
3. Wait for approval
Processing times may vary, so we recommend that you submit your application as early as possible in your process to avoid any delays.
What are the risks if I carry out work without a permit?
Carrying out renovations without a permit may result in:
- fines,
- mandatory work stoppage,
- the obligation to redo everything according to standards,
and problems when reselling your property (yes, undeclared work may come to light during the inspection).
