BramptonTwo-unit dwelling registration
Legal basement apartment in Brampton
A legal basement apartment in Brampton costs $75,000 to $110,000 or more to build with Desire Basements and takes about three months. Unlike Toronto, Brampton runs a mandatory registry: the suite is applied for as a Two-Unit Dwelling, pays a $200 registration fee plus a $1,186.24 permit fee, passes the City's mandatory inspections, and receives a registration certificate when occupancy is granted. Only then is it legal to rent.
The registration path, in Brampton's order
Every GTA city applies the same Ontario Building Code. What changes at the Brampton counter is the registry, and the sequence below is the City's own. We run all of it; you sign the application.
- 1
Confirm the lot can take a second unit
Brampton's zoning summary for a two-unit dwelling sets five conditions: one second unit per house; the unit smaller than the principal dwelling; no extra parking, but the lot keeps the minimum spaces it already needs; an entrance in the side or rear yard with a 1.2 m unobstructed path to the front, entirely on your property, or an entrance through the garage or a shared vestibule; and no units on Open Space, Floodplain or Downtown Floodplain Regulation lands. Properties inside Credit Valley Conservation or TRCA regulated areas need the conservation authority's approval first, or the permit stops.

Design and 3D
A free in-home visit, a ceiling-height check against the 1.95 m Part 11 minimum, and a free 3D design of the suite. Permit drawings are prepared and stamped by a licensed structural engineer while the design is finalized.

File the Two-Unit application
Through the Brampton Building and Business Portal: the Application for Registration and Change of Use Building Permit, Two-Unit Dwelling; the $200 registration fee and the $1,186.24 permit fee; a legible legal survey with the surveyor's signature (the City does not keep surveys for every property); and complete drawings.

Build to Part 11
About three months, with a written completion date backed by our $200 a day on-time guarantee. Fire separation, interconnected alarms, the egress window or separate entrance, the kitchen and bathroom rough-ins all go in as visible lines on the quote.

Pass the mandatory inspections
Brampton publishes a list of mandatory inspections for two-unit dwellings and charges an Inspection Recall Fee once an inspection fails twice. We book each one and are on site for it. The electrical work is inspected by the Electrical Safety Authority; the City now notifies the ESA about new units itself, so you no longer email the ESA certificate to the zoning office.

Registration certificate
Issued when occupancy is granted on the permit. The address joins Brampton's public map of registered additional residential units, which is what a careful tenant, a mortgage lender and your insurer will look for.
What the inspector measures
The 2024 Ontario Building Code provisions for a secondary suite in an existing house, and what each one means on site. These are the items a cheap quote leaves out.
Ceiling height
6 ft 5 in, with 1.85 m allowed under beams and ducts. Lower than that is underpinning or bench footing before anything else.
Fire separation
Between the suite and the rest of the house, floor assembly and shared walls, doors included.
Egress window
Clear opening with no side under 380 mm; it must open without tools and stay open on its own.
Smoke alarms
Interconnected through the house, so a fire in one unit wakes the other. Carbon monoxide alarms by every sleeping area.
Suite door
Bedroom doors at least 760 mm. Old 24-inch basement doors do not pass.
Entrance
A side or rear entrance with the 1.2 m path, through the garage, or a fire-separated shared vestibule. A new walkout runs $15,000 to $25,000 all in.
What a Brampton suite costs
Every basement is priced from the same quote sheet, line by line: a 1,000 sq ft basement with a three-piece bathroom comes to about $67,800 before HST, and the price per square foot falls as the basement grows because the permit, bin, breakers, stairs and bathroom cost the same at any size. A suite is the same build with the Code items added as lines you can read: kitchen rough-ins at $1,800, the fire separation, the alarms, the egress window or entrance. That is how a purpose-built Brampton suite lands at $75,000 to $110,000 or more.
Brampton's newer subdivisions usually clear the 1.95 m minimum, so the $60,000 to $120,000 underpinning bill that decides many Toronto projects is less common here. Where a ceiling falls short, we say so at the first visit with the number attached.
- City fees, registration plus permit$1,386.24
- 1,000 sq ft, three-piece bathroom, standard buildabout $67,800
- Walkout or side entrance, permits included$15,000 to $25,000

GTA legal suites rent for $1,700 to $2,400 a month in 2026. At $2,000 a month a $95,000 suite pays back its gross cost in roughly four years, before property tax, insurance, utilities and income tax. Since May 2023 Brampton allows a principal dwelling plus two more units, as a second and third unit inside the house or a second unit plus a garden suite, and a registered second unit can be followed by a third on its own application. We build the basement unit; we do not build garden suites. The rental income guide runs the arithmetic, and the financing page covers the CMHC refinance that funds up to 90% of the home's post-renovation value.
Brampton questions
How much does a legal basement apartment cost in Brampton?
$75,000 to $110,000 or more with Desire Basements for a purpose-built suite, before HST, with the City's $200 registration fee and $1,186.24 permit fee on top. A 1,000 sq ft basement with a three-piece bathroom prices at about $67,800 on our quote sheet; the kitchen, fire separation, alarms and entrance are added as visible lines.
Does a basement apartment have to be registered in Brampton?
Yes. The City states that second units, third units and garden suites must be registered with the City of Brampton to be legal. Registration runs through the Two-Unit Dwelling building permit, mandatory inspections and a registration certificate issued when occupancy is granted.
Do I need extra parking for a second unit in Brampton?
No. Brampton's zoning summary says no additional parking is required to create a second unit, but the lot must keep the minimum parking spaces the Zoning By-law already requires for the house.
Where can the entrance to a Brampton basement apartment be?
In the side or rear yard, as long as there is a 1.2 m unobstructed path to the principal entrance located entirely on your property, or inside the garage, or through a common vestibule in the house. A side-yard landing is allowed if it is under 0.6 m high and no more than 0.9 m by 0.9 m.
How long does a legal suite take in Brampton?
About three months of construction with a written completion date backed by our $200 a day on-time guarantee, plus the City's permit review before and the inspections and occupancy at the end. Permit drawings are stamped by a licensed structural engineer and filed while the 3D design is finalized.
