## How much does a legal basement apartment cost by scope?

A legal one-bedroom basement apartment costs $60,000 to $90,000 in Brampton, says Raj Renos, and a two-bedroom costs $80,000 to $120,000 or more. GoGajic prices a Brampton suite at $55,000 to $90,000 when the house already has a side entrance. A plain basement finish with no second unit costs $28,000 to $44,000, so the suite roughly doubles the bill.

| Legal suite or high end, 500 sq ft basement (Toronto) | $55,000 to $80,000 | [Senso Design](https://sensodesign.ca/basement-renovation-toronto/) |

Brampton houses often start ahead. GoGajic says most Brampton detached homes built after 1995 have 8 to 9 foot basement ceilings, so a suite rarely needs underpinning. Older Toronto bungalows are a different case: Desire Basements puts full-perimeter underpinning at $60,000 to $120,000 when the ceiling is too low.

## What do the entrance, egress and drawings cost?

The separate entrance is the biggest single add-on. Raj Renos prices a new side entrance, with the wall cut and stairwell, at $15,000 to $30,000 in Brampton. Each new egress window runs $2,500 to $5,000 installed, says GoGajic, and permit drawings by a qualified designer cost $1,500 to $4,000, says GS Arora Law.

- **New separate side entrance:** $15,000 to $30,000 ([Raj Renos](https://www.rajrenos.ca/legal-basement-apartment-brampton.html)); walkout basement entrance, $15,000 to $25,000 all in ([Desire Basements](https://www.desirebasements.com/basement-finishing-cost-toronto)).
- **Existing side entrance:** saves $8,000 to $15,000 in entrance work ([GoGajic](https://gogajic.ca/basement-renovation-brampton/)).
- **Egress window:** $2,500 to $5,000 each, installed ([GoGajic](https://gogajic.ca/basement-renovation-brampton/)).
- **Full bathroom add-on:** $8,000 to $15,000 ([Raj Renos](https://www.rajrenos.ca/legal-basement-apartment-brampton.html)).
- **Designer or architect drawings:** $1,500 to $4,000 ([GS Arora Law](https://www.gsaroralaw.ca/blog/the-2026-guide-to-legalizing-your-brampton-basement-apartment-requirements-zoning-and-safety)).
- **Electrical inspection and panel upgrade, if needed:** $200 to $3,500 or more ([GS Arora Law](https://www.gsaroralaw.ca/blog/the-2026-guide-to-legalizing-your-brampton-basement-apartment-requirements-zoning-and-safety)).
- **Contingency:** 10% to 15% of the budget ([Raj Renos](https://www.rajrenos.ca/legal-basement-apartment-brampton.html)).

Raj Renos names four big cost variables: the separate entrance, ceiling height corrections, how far the new kitchen and bathroom sit from the main stack, and electrical service upgrades. Ask each bidder to price those four lines on their own. Our [basement finishing cost guide](https://www.prohousemaintenance.com/blog/basement-finishing-cost/) covers the rest of the finish.

## What makes a basement apartment legal in Ontario?

A basement apartment is legal once it is built under a permit, passes inspection and is registered with the city. Desire Basements says the 2024 Ontario Building Code allows a suite in an existing house with a ceiling as low as 1.95 metres, or 1.85 metres under beams and ducts. The suite also needs fire separation, linked smoke alarms, a separate exit and egress windows.

- **Ceiling height:** at least 1.95 metres (about 6 feet 5 inches), or 1.85 metres under beams and ducts, in an existing house ([Desire Basements](https://www.desirebasements.com/basement-finishing-cost-toronto)).
- **Egress windows:** at least 0.35 square metres of clear opening, with no side shorter than 380 mm ([Desire Basements](https://www.desirebasements.com/basement-finishing-cost-toronto)).
- **Fire separation:** a 30-minute fire separation between the units, smoke alarms linked throughout the house and carbon monoxide alarms beside every bedroom ([Desire Basements](https://www.desirebasements.com/basement-finishing-cost-toronto)).
- **Units per lot:** Brampton has allowed up to 3 units on a property, including the main house, since May 2023 ([City of Brampton](https://www.brampton.ca/EN/residents/Building-Permits/second-dwelling)).
- **Parking:** Brampton requires no extra parking space for one additional unit, but a lot with more than one needs extra parking ([City of Brampton](https://www.brampton.ca/EN/residents/Building-Permits/second-dwelling)).

Brampton says unregistered units may face enforcement, including fines and legal action, plus insurance consequences, and that every additional unit must be registered even if family lives there. Some lots near rivers also need conservation authority approval before a permit can proceed ([City of Brampton](https://www.brampton.ca/EN/residents/Building-Permits/second-dwelling)).

## What do GTA cities charge to permit and register a second unit?

Brampton charges a flat $1,186.24 in 2026 for a change of use to create a second dwelling unit. Toronto adds $56.33 for each new unit on top of its $6.20 per square metre basement finishing rate. Mississauga charges $11.33 per square metre plus its minimum fee, then refunds the permit fee once the unit passes its inspections.

| Brampton | Change of use to create a second unit: $1,186.24 flat. Basement finish: $326.21 flat. Below-grade entrance: $326.21 flat. New door opening: $133.61 each. | [City of Brampton](https://www.brampton.ca/EN/residents/Building-Permits/Documents/Fees/Permit%20Fee%20Schedule.pdf) |
| Brampton | Residential Rental Licence, required before renting: free | [City of Brampton](https://www.brampton.ca/EN/residents/Building-Permits/second-dwelling) |
| Toronto | Basement finishing: $6.20 per m2. Each new residential unit: $56.33. Minimum fee: $214.79. | [City of Toronto](https://www.toronto.ca/services-payments/building-construction/building-permit/before-you-apply-for-a-building-permit/building-permit-fees/) |
| Mississauga | Additional unit within an existing building: $11.33 per m2 plus the $244 minimum residential fee | [City of Mississauga](https://www.mississauga.ca/wp-content/uploads/2026/03/03153640/Schedule-B-2026-Classes-of-Permits-and-Fees.pdf) |
| Mississauga | Permit fee refunded after the unit is built and passes all inspections. Registering a second unit: no fee. | [City of Mississauga](https://www.mississauga.ca/services-and-programs/building-and-renovating/building-more-units-on-your-property/additional-residential-units/), [registration](https://www.mississauga.ca/services-and-programs/building-and-renovating/registering-a-second-unit/) |

Fail an inspection twice in Brampton and an inspection recall fee applies to each visit after that, so book inspections only when the work is ready. Brampton says you do not need to submit your ESA certificate to finish registration, but the unit must still comply with the Electrical Safety Code. For permit counts and timelines, see our [building permit statistics](https://www.prohousemaintenance.com/blog/building-permit-statistics/).

## How fast does a legal basement apartment pay for itself?

A legal Brampton basement suite rents for about $1,400 to $2,200 a month, based on figures from GoGajic and Raj Renos, and both firms' worked examples pay back in about four years. Desire Basements puts GTA legal suite rents at $1,700 to $2,400 a month and says a $95,000 suite at $2,000 a month pays back in about four years.

**GTA legal basement suite rents and payback, as published by each firm (CAD)**

| Scope | Monthly rent | Payback example | Source |
| --- | --- | --- | --- |
| Brampton one-bedroom suite | $1,400 to $1,800 | $75,000 suite at $1,600 a month: about 47 months | [GoGajic](https://gogajic.ca/basement-renovation-brampton/) |
| Brampton two-bedroom suite | $1,700 to $2,200 | $85,000 suite at $1,900 a month: about 4 years after taxes, insurance and maintenance (Raj Renos) | [GoGajic](https://gogajic.ca/basement-renovation-brampton/), [Raj Renos](https://www.rajrenos.ca/legal-basement-apartment-brampton.html) |

Those payback figures come from firms that build suites, and most leave out vacancy. Brampton notes that MPAC may raise your assessment after a suite is added, and tells owners to notify their insurance company. If the suite lets a senior, or an adult eligible for the disability tax credit, live with a qualifying relative, the federal Multigenerational Home Renovation Tax Credit refunds 14.5% of up to $50,000 in costs, a maximum of $7,250 ([Canada Revenue Agency](https://www.canada.ca/en/revenue-agency/services/tax/individuals/topics/about-your-tax-return/tax-return/completing-a-tax-return/deductions-credits-expenses/line-45355-mhrtc.html)).

## How do you get an accurate legal basement apartment quote?

Start by measuring the ceiling height and checking whether the house has a side door. Ask each contractor to price the entrance, egress windows, fire separation, bathroom, kitchen and any panel upgrade as separate lines. Confirm who prepares the drawings and pulls the permit, and compare at least three quotes on the same scope.

If a separate unit in the yard suits your lot better, our [garden suite statistics](https://www.prohousemaintenance.com/blog/garden-suite-statistics/) cover that route, and the [general contractor cost guide](https://www.prohousemaintenance.com/blog/general-contractor-cost/) explains GC fees.
