Yes. The City of Brampton requires a building permit to finish a basement. Electrical work also needs a separate notification to the Electrical Safety Authority. This guide walks through what the City asks for, the typical process from application to final inspection, and why a finished basement is not the same thing as a legal basement apartment.
Key points
- Finishing a basement in Brampton needs a building permit. Damp-proofing alone may not.
- The City’s Basement Finish package lists exactly what your plans must show.
- Applications and inspection bookings go through the Brampton Building and Business Portal.
- A Basement Finish permit cannot be used to create a separate dwelling unit.
- Second and third units must be registered with the City, and renting requires a Residential Rental Licence.
What counts as finishing a basement?
Finishing usually means turning unfinished space into living space: framing walls, insulating, adding drywall and ceilings, building rooms, adding a bathroom, and installing lighting and flooring. That is the work covered by the City’s Basement Finish permit (Basement Finish Package).
Some work on its own is treated differently. The City lists damp-proofing a basement among projects that may not need a building permit, but that does not remove the permit requirement once you go on to finish the space (City of Brampton).
What the Basement Finish application includes
The City’s package (requirements revised February 2026, forms revised April 2026) states that its information is required at submission and that incomplete applications cannot be accepted. It asks for:
- A completed application through the Brampton Building and Business Portal
- Schedule 1 (designer information), the Applicable Law Checklist and Schedule A (Basement Finish Declaration)
- Scaled plans showing room uses and dimensions, window locations and sizes, construction details and plumbing fixtures
- The location of smoke alarms
- A bathroom exhaust fan location if the bathroom has no openable window
- A three-way light switch at the top and bottom of the stairs
Window sizes for bedrooms and living areas
The package sets minimum window areas as a percentage of the room’s floor area. A basement recreation room does not require a window.
| Room | House less than 5 years old | House more than 5 years old |
|---|---|---|
| Living or dining room | 10% of floor area | 5% of floor area |
| Bedroom | 5% of floor area | 2.5% of floor area |

Fees
The package lists a fee of $326.21 for the standard 10-day permit application, plus $133.61 for each new window or above-grade exterior door. Fees change, so confirm the current amount with the City before you apply.
Who prepares the drawings?
Schedule 1 asks for the responsible designer’s name, firm and BCIN (Building Code Identification Number). Architects and professional engineers are exempt from completing Schedule 1. If you are unsure who can prepare drawings for your project, ask the Building Division before you start.
The typical process, step by step
- Check for moisture first. Musty smells, water stains, white deposits on the foundation and peeling paint near the floor are warning signs. Fix the cause before planning finishes.
- Plan the layout. Decide room uses, bedroom windows, bathroom location and where the ducts, beams and plumbing will need bulkheads.
- Prepare the drawings and forms. Follow the Basement Finish package checklist so the application is complete.
- Apply through the portal. Submit the application and drawings through the Brampton Building and Business Portal.
- Build and book inspections. Inspections are requested online through the same portal, up to 5 days ahead, with next-day bookings closing at 3:00 p.m. (City of Brampton inspections).
- Notify ESA for electrical work. Electrical work follows its own notification and inspection process (ESA).
- Pass the final inspection. The permit is complete once the final inspection passes.
Common inspection stages
Your permit card lists the inspections that apply to your project. For a typical basement finish they can include:
- Plumbing rough-in: drains, supply and venting installed and ready for testing
- Structural framing: after rough-ins pass and before insulation
- Insulation and vapour barrier: complete before drywall goes up
- Final: all construction complete

The two are easy to confuse, but a finished basement and a legal basement apartment follow different rules.
Finished basement:
- Extra living space that stays part of a single home
- Covered by the Basement Finish permit
- Schedule A requires the owner to declare the basement will not be used as a separate dwelling unit
Additional residential unit (ARU):
- A self-contained unit inside the home, such as a second or third unit
- Up to three units per property, including the main home
- Must be registered with the City, even if it is not rented
- A below-grade entrance needs specifications from an engineer or BCIN-qualified designer
According to the City’s Additional Residential Units page, a building permit application for an ARU must include a legal survey, and properties in conservation-authority regulated areas need that authority’s approval. The Zoning By-law does not require an extra parking space for a lot with one ARU, but lots with more than one ARU need additional parking.
Renting the space
Brampton’s Residential Rental Licensing program is citywide: all wards require licensing beginning January 1, 2026, and owners renting properties with one to four units must hold a Residential Rental Licence (City of Brampton RRL FAQ). The City’s ARU page also states that a unit cannot be rented or occupied until a licence is obtained.
If you are considering a rental unit, start with the City’s ARU and rental licensing pages and speak with the Building Division before any design work.
Why the permit is worth it
Inspections check work that is hidden once the drywall goes up: framing, plumbing, insulation and the vapour barrier. The permit also confirms safety items the City requires on the plans, such as smoke alarm locations, stair lighting controls and bathroom ventilation. A closed permit gives you a clear record of the work when you sell or insure your home.
Frequently asked questions
Do I need a permit just to add drywall and flooring?
If you are finishing unfinished space into living space, the City’s Basement Finish permit applies. For smaller jobs, check the City’s list of work that does not require a permit and confirm with the Building Division at 905-874-2401.
Can I use a Basement Finish permit for a basement apartment?
No. The City’s package states the application is not to be used for a second unit dwelling. Second and third units follow the separate ARU process and registration.
How do I book inspections?
Through the Brampton Building and Business Portal. The City lists inspection hours as 8:00 a.m. to 4:00 p.m. on weekdays, excluding statutory holidays.
