A basement apartment in Brampton is legal only when it is registered with the City. A separate entrance, a second kitchen and a tenant do not make it legal. Registration does, and it happens once the unit has a building permit and has passed its inspections.
The city’s own fees are small: $1,386.24 in total. The construction is where the money goes. This guide covers the rules, the six steps, the realistic cost, what units rent for, and what happens when you sell a house with a unit that was never registered.

What Brampton allows on one lot
The City calls these additional residential units, or ARUs. Each is a self-contained home with its own kitchen and bathroom. On a detached, semi-detached or street townhouse lot you can have up to three units, in one of two combinations:
- the main home, one attached second unit such as a basement apartment, and one garden suite in the rear or side yard, or
- the main home, one attached second unit and one attached third unit.
The basement apartment is by far the most common. Three rules shape whether your basement qualifies:
- Size. The second unit must be smaller in floor area than the main home. There is no fixed maximum.
- Entrance. It can be at the side or rear, as long as there is a 1.2 metre unobstructed path to it that sits entirely on your own property. This is the rule that catches narrow side yards. Measure yours before you spend anything.
- Landing. A landing at the unit entrance must be less than 0.6 metres above the ground and no more than 0.9 metres long or wide.
You do not need to add a parking space for the second unit. You do have to keep the number of spaces the zoning by-law already requires for the lot.
Registration in six steps
Step 1 of 6: Check the registry and the zoning
Look up the address on the City’s list of properties with registered ARUs, found through the Brampton GeoHub map. If the unit is already there, you are done. If not, read the zoning requirements for two-unit dwellings and check the side yard path and landing against your lot.
Step 2 of 6: Get drawings
The application needs a legal survey signed by a surveyor and a full set of drawings: a dimensioned site plan, existing and proposed floor plans for every level, elevations showing the entrance and escape windows, and construction details for the fire separation and the windows. Most owners hire a designer with a BCIN number for this.
Step 3 of 6: Apply online and pay
Submit the “Application for Registration and Change of Use Building Permit, Two-Unit Dwelling” through the Brampton Building and Business Portal. You pay the $200 registration fee and the $1,186.24 permit fee together.
Step 4 of 6: Build to the permit
Once the permit is issued, the work can start. The Building Code items that drive the cost are the fire separation between the units, a proper escape route from the basement, ceiling height, smoke and carbon monoxide alarms that are wired together, and separate or protected heating and ventilation. Your designer’s drawings set out exactly what your house needs.
Step 5 of 6: Pass the inspections
The City inspects at set stages, and you book each one. If an inspection fails twice, later visits carry a recall fee. Electrical work is inspected separately by the Electrical Safety Authority. Since March 2025 you no longer have to email the ESA certificate to the City yourself.
Step 6 of 6: Registration and licence
When the final inspection approves occupancy, the unit is registered. That registration is permanent and stays with the house. If you rent the unit out, you also need a residential rental licence, which is a separate City program covered below.

What it costs
| Item | Cost | Source |
|---|---|---|
| Registration fee | $200 | City of Brampton |
| Building permit fee | $1,186.24 | City of Brampton |
| Survey, if you do not have one | About $1,500 to $2,500 | Our estimate |
| Permit drawings | About $2,000 to $5,000 | Our estimate |
| Upgrading a finished basement to code | About $25,000 to $50,000 | Our estimate |
| Building a unit in an unfinished basement | About $60,000 to $120,000 | Our estimate |
Only the first two rows are fixed. The rest depend on your house, and contractor quotes vary widely. Get three, and make sure each one prices the same permit drawings.
What pushes a quote up: cutting a new side entrance and stairwell, enlarging a window for escape, lowering the floor to gain ceiling height, and moving ductwork. What keeps it down: a house that already has a walk-out or a builder-installed side door, and a basement with full-height ceilings.
What a legal unit rents for
Listings on Rentals.ca in mid-2026 give a sense of the range. The sample is small, at 18 basement listings, so treat it as a guide.
| Unit | Asking rent | Listings |
|---|---|---|
| One bedroom | $1,200 to $1,600 | 2 |
| Two bedrooms | $1,700 to $2,250 | 11 |
| Three bedrooms | $1,860 to $2,350 | 3 |
Two-bedroom units make up most of the market. A newer, registered unit with its own laundry and a proper entrance sits at the upper end of each range.
Does it pay? Run your own numbers
Enter what the work will cost, the rent you expect and your running costs. The default is a $75,000 build renting at $1,900 with one empty month a year.
On those defaults the unit nets $17,900 a year and pays for itself in about 4.2 years, before income tax. Rent is taxable income, and a rented portion of your home can affect the principal residence exemption when you sell, so speak to an accountant before you count on the full amount.
The rent also helps you carry the house. On a mortgage at today’s variable rates, $1,900 a month covers the payment on roughly $380,000 of borrowing. See current variable mortgage rates for the numbers behind that.
The rental licence
Registration deals with the building. The Residential Rental Licensing program deals with you as a landlord. It began as a pilot in a few wards and now applies across the city: as of January 1, 2026, owners of all rental properties in Brampton must hold a licence, and existing licence holders had to renew by January 31, 2026.
The licence is renewed every year, and the City can inspect a licensed property. Check the City’s renting page for the current fee and the documents required, because both have changed as the program expanded. A registered unit is the starting point for a licence. An unregistered one cannot be licensed properly.
What an unregistered unit costs you
Fines
The City lists a fine of $1,000 to $1,500 for failing to register an ARU. A charge under the Planning Act is far heavier, from $25,000 up to $1.5 million. The City can also order the unit vacated and the kitchen removed.
Insurance
Home insurers ask whether any part of the home is rented. If there is a fire in a unit the insurer did not know about, or one built without a permit, the claim can be reduced or denied. That risk is larger than any fine.
Your tenant
An unregistered unit does not take away a tenant’s rights. Ontario’s Residential Tenancies Act still applies, so you cannot simply end the tenancy because the City has found the unit. You can end up paying to rehouse a tenant while also paying to fix or remove the apartment.
Selling a house with a basement apartment
This is where owners are most often surprised.
- The word “legal” is a promise. If a listing describes the basement as legal, the buyer is entitled to rely on it. Without a registration to show, that is a misrepresentation, and the seller and the agent are both exposed. The honest wording for an unregistered unit is “finished basement with separate entrance”, with a clause stating that the seller does not warrant its legal use.
- Buyers will check. The City’s registry is public. A buyer’s agent or lawyer can look up the address in a minute.
- Lenders treat the rent differently. A lender will usually count rent from a registered unit toward the buyer’s qualification. Many will not count rent from an unregistered one. That shrinks the pool of buyers who can afford your price.
- Price. A registered unit is an asset a buyer pays for. An unregistered one is a job the buyer has to finish, and they will price in the cost and the risk.
If you plan to sell within a year or two, registering first usually returns more than it costs. If the basement cannot meet the rules, say because the side yard is too narrow, it is better to know that before you list. Our guide to selling your home covers how second units and tenants affect timing.
Buying a house for the basement income
Ask for proof of registration with the offer, not a description. Make the offer conditional on confirming it with the City. Ask for the current lease and the rent actually paid, since an existing tenant stays on the same terms after closing.
Some new homes are built for this from the start. Arbor West in northwest Brampton offers a layout with two separate entrances, two kitchens and a finished basement suite, which removes most of the conversion cost. Ask the builder to confirm in writing that the second unit will be delivered ready to register.

Questions owners ask
How do I check if a basement apartment in Brampton is legal?
Search the address on the City’s list of registered additional residential units, available through the Brampton GeoHub map, or call 311. If the address is not listed, the unit is not registered.
How much does it cost to register a basement apartment in Brampton?
The City charges $200 for registration and $1,186.24 for the permit, $1,386.24 in total. Construction to meet the Building Code is extra and is the larger cost.
Do I need an extra parking space?
No. No additional parking is required for a second unit, but the lot must keep the minimum spaces already required by the zoning by-law.
Can I register a basement that was finished years ago?
Yes. The process is the same. The City will require the existing work to meet today’s code, which can mean opening walls or ceilings so the fire separation and wiring can be inspected.
Can I have a basement apartment and a garden suite?
Yes. Brampton allows the main home plus one attached second unit and one garden suite, for three units in total.
Is registration the same as a rental licence?
No. Registration is a one-time approval of the unit. The rental licence is an annual requirement for anyone renting out a property in Brampton.
