Does the City of Toronto allow basement Airbnb rentals and what regulations apply?

Yes, the City of Toronto permits basement short-term rentals (Airbnb and similar platforms) but only under specific conditions set out in the city's short-term rental bylaw, Chapter 547, which took effect in 2018 and has been actively enforced since. Understanding these regulations before investing in a basement conversion can save you from fines, legal complications, and wasted renovation spending.

The fundamental rule is that short-term rentals are only permitted in your principal residence — the home where you live as your primary dwelling. You cannot operate a short-term rental in a secondary property, investment property, or any home that is not your principal residence. This means you must actually live in the house where the basement unit is located. If you rent out the entire house (leave during the guest's stay), you are limited to 180 nights per calendar year. If you rent the basement while you continue to live upstairs, there is no night limit because you are renting a portion of your home while remaining present.

Registration is mandatory. Every short-term rental operator in Toronto must register with the City through the Municipal Licensing and Standards division. The registration costs approximately $50 per year, and your registration number must be displayed in every listing on every platform. Operating without registration can result in fines of up to $10,000 per offence. The City actively monitors listing platforms and pursues unregistered operators.

Tax obligations include the Municipal Accommodation Tax (MAT) of 6% on the total price of every short-term rental booking. Airbnb and most major platforms collect and remit MAT automatically on your behalf, but if you book through other channels, you must collect and remit it directly. Short-term rental income is also taxable income for provincial and federal income tax purposes — you can deduct a proportional share of household expenses (property tax, insurance, utilities, mortgage interest) against rental income, but you must report it on your tax return.

Building code compliance is non-negotiable. A basement unit used for short-term rental accommodations must meet the Ontario Building Code requirements for a secondary suite, including 1-hour fire-rated separation between the unit and the rest of the house, egress windows in every bedroom meeting minimum size requirements (3.77 square feet unobstructed opening), interconnected smoke and carbon monoxide detectors, adequate plumbing, electrical, heating, and ventilation, and minimum ceiling height of 6 feet 5 inches (1.95 metres) in existing homes. Building permits are required, and the City of Toronto Building Division will inspect the work. An unpermitted basement suite operating as an Airbnb faces both building code enforcement (orders to cease use, tear-out orders) and short-term rental bylaw enforcement (fines, registration revocation).

The City of Toronto has a dedicated enforcement team for short-term rental compliance. They respond to complaints from neighbours, proactively monitor listing platforms, and conduct inspections. Violations can result in orders to comply, fines of up to $10,000, and revocation of your registration. Repeat offenders face escalating penalties. The city also requires that operators maintain records of all bookings for inspection upon request, including guest names, dates, and amounts charged.

Zoning considerations: secondary suites, including those used for short-term rental, are permitted in most residential zones across Toronto under the city's as-of-right secondary suite permissions. However, some areas have specific restrictions, and condo townhouse declarations may prohibit short-term rentals regardless of city zoning. Check with your local councillor's office or Toronto Building if you are unsure about your property's zoning.

Practical requirements include providing guests with information about garbage and recycling schedules (Toronto's strict waste sorting bylaws apply to guests), parking arrangements (street parking permits may be needed), and noise expectations. You are responsible for your guests' behaviour, and repeated noise complaints or bylaw violations related to your rental can trigger enforcement action against you as the operator.
