Finished basement
Finish the basement as a rec room, office, gym or guest room. You still need a permit, but second-unit requirements such as a separate entrance and registration do not apply.
Permit basicsYour basement renovation in Brampton starts with how you want to use the space. A family room, in-law suite and legal rental unit each need different work and permits. We help you choose before construction starts.

Yes, if the work includes walls, plumbing, electrical work or a bedroom. If you plan to rent the basement, it must also meet the second-unit requirements, pass inspection and be registered with the city.
How you plan to use the basement determines the permits, inspections and budget. That is where we start.

Permit basicsBuild a self-contained basement apartment you can rent legally. We plan the work around the city's inspections from the start.
Legal basement renovationExisting finishes can hide work the inspectors need to see. Opening parts of the floor and walls often makes legalization a larger job than expected.
Legalize a basementThese parts of the build determine whether the basement can become a legal unit. Planning for them now can avoid removing and replacing finished work later.
Bedroom windows need a clear opening of at least 0.35 square metres, with no side smaller than 380 mm.
Egress windowsAn above-grade side door usually costs about $2,000 to $3,000. A basement walkout below ground level costs more.
Walkouts and entrancesFire separation covers the area between units, beneath the stairs and around the furnace room. The furnace room usually also needs sprinklers.
What inspectors checkA second household increases electrical demand. The legal basement projects we have built have needed 200 amp service.
Legal unit requirementsThe drain line needs a clean-out, and the underground plumbing must be inspected before the floor is closed.
Venting needs the correct pipe size and material. In most locations, the city requires 6-inch hard pipe.

Brampton basements
People expect legalizing a finished basement to be a small job because the basement is already done. It usually isn't. The inspector has to see what's behind the finishes, and a lot has to be undone for that.
In our experience, a simply finished basement usually lacks several requirements for a legal unit. Legalization usually starts around $40,000, though it can cost less when more of the existing work already meets those requirements.
The intended use and existing work set the budget. Legalizing a finished basement usually starts around $40,000. A complete legal basement renovation from unfinished starts around $60,000. Legalization can cost less when more of the requirements are already met, although that is unusual in our experience.

Your written quote lists each part of the work. We base it on a basement walkthrough as well as the size of the space.
Read the guidance for your project, then find answers to the questions that come up before work starts.
Before you start, check Brampton's basement finishing permit requirements. A rental apartment follows the separate Additional Residential Unit process, with different drawings and approvals. Plan the work around the city's inspection stages so nothing gets covered before it is checked.
Yes, when basement finishing includes walls, plumbing, electrical work, a bedroom, windows or an entrance. The city requires scale drawings and lists the standard basement finish permit fee at $326.21.
Submit scale drawings with each room's dimensions. A second unit also needs a legal survey and drawings prepared by a qualified designer.
The standard basement finish permit fee listed by the city is $326.21. Separate fees apply to second-unit permits and registration.
City inspections take place at different stages. For second units, book the final building, plumbing and HVAC inspections on the same day.
A family rec room and a rental apartment follow different approval paths. Brampton's second-unit zoning requirements cover access, while a rental unit also needs fire separation, registration and a Residential Rental Licence. Bedrooms need an emergency exit even when the basement is for family use.
A family basement uses the stairs. A rental apartment needs its own entrance or shared access with a 1.2 metre path.
Yes, unless that level has a door to the outside. The egress window must have a clear opening of at least 0.35 square metres, with no side smaller than 380 mm. A rec room does not require a window.
Fire separation must divide the rental unit from the main home, including beneath the stairs and around the furnace room.
No. To rent it legally, the unit must pass city inspections and be registered, and you must have a Residential Rental Licence. Legalization usually starts around $40,000 because a simply finished basement often lacks several legal-unit requirements. It can cost less when more of those requirements are already met.
We discuss your plans and check the space, including bedrooms or future rental use that may affect permits.

Working with KDM has been a complete pleasure. The entire team was friendly, prompt, efficient, and thorough. They under promised and over delivered. I got a beautiful basement that I am completely happy with in a timeframe that was barely an inconvenience. They cleaned before, during, and after so it was easy to move into the space.

I found Mike and his team for my parents who live in Brampton. They were able to respond very quickly to our request for both renovations and handyman work. They completed the job very quickly, the quality is first class, and the price was super reasonable.
