Required Permits and Where to Find Them
Depending on how much work you are planning on doing during your renovation, you may need to apply for multiple permits in order to begin construction. All the permits that you might possibly need can be found on this government website.
- First you will need to complete a detailed construction permit application form, which outlines the details of your project, including estimated costs and the contact details of all the professionals you will be hiring.
- You will also need to complete the Building Sub-Code Technical Section for any structural changes to your basement, such as adding windows or doors.
- If you plan on making any electrical alterations or additions, you will need to complete the Electrical Sub-code Technical Section. This is a short, but detailed form, which includes all the information regarding the electrical components of your renovations.
- When adding or altering any plumbing in your basement, you will need to fill out the Plumbing Sub-Code Technical Section that outlines exactly what changes you will be making.
Supplementary Documentation Required
With your completed permit application form, you will also need to submit additional documentation when applying for a building permit.
You will be required to attach two copies of your building plans to your application. These drawings must be extremely clear to ensure they are legible by the officials reviewing your application, and must contain the exact address where the building will take place.
The drawings need to be as in-depth as possible, showing the entire floor plan with indications of windows, doors, flooring, electrics and plumbing layouts, and stairways. They also need to show the exact dimensions of the entire space, including ceiling height.
You will also need to supply the municipality with the electrical and plumbing plans, which are in line with the city’s building codes.
How Much It Will Cost
When setting out your budget for your renovation project, you also need to make provisions for your permit fees.
When finishing your basement, you will need to pay a fee of $50 to the municipality in order for them to review your application.
You will also need to pay a separate amount depending on how much your entire renovation will cost. Making alterations to your basement will cost you $25 per every $1000 you plan on spending on your construction project.
If you happen to change contractors during your project, not only will you have to re-fill all your application forms with the new contractors details, you will also have to pay $50 per application that you have to change.

How Long Approval Will Take
From the moment you submit your applications and all necessary additional documentation, you can expect to wait up to three weeks to receive the outcome. This period is if you plan on making extensive changes to your basement, like making new walls or extending it.
However, with less extreme changes you can expect to receive your approval in as little as 7 days if all your applications and documentation is in order.
Regardless of how long the answer is taking, you do not want to start your finishes before you have received your permit.
