A strategy where the homeowner lives in one part of a property and rents out the rest to offset mortgage and housing costs. Common forms include renting out a legal basement apartment, purchasing a duplex and living in one unit, or renting spare bedrooms. In Ontario, house hacking must comply with local zoning bylaws and any basement suite must meet Ontario Building Code requirements for a second unit.
Why It Matters
House hacking is one of the most accessible ways to start investing in the GTA, where purchase prices are high and rental demand is strong. A legal basement apartment in Toronto or the 905 can generate $1,500 to $2,500 per month, significantly reducing your effective housing costs. Many first-time buyers use this strategy to qualify for a larger mortgage, since lenders may count a portion of the expected rental income toward your debt servicing ratios.
Real-World Example
You purchase a detached bungalow with a legal basement apartment in East York for $850,000 with 10% down. You live upstairs and rent the basement for $1,800 per month. Your total monthly carrying costs are $4,200 including mortgage, property tax, and insurance. The $1,800 basement rent reduces your effective housing cost to $2,400 per month -- comparable to renting a one-bedroom condo downtown, but you are building equity in an asset worth $850,000. Your lender counted 50% of the expected basement rent as income when qualifying you, which increased your maximum purchase price by approximately $90,000.
Ontario & GTA Context
Ontario's Bill 23 (More Homes Built Faster Act) made it easier to add secondary suites by requiring municipalities to allow up to three units on most residential lots as of right. In Toronto, the city's Changing Lanes initiative legalized laneway and garden suites as additional rental options. Any basement apartment must meet Ontario Building Code requirements for ceiling height (minimum 6 feet 5 inches in most areas), egress windows, fire separation, and independent HVAC. A building permit is required, and inspections will verify compliance.
How It Works in Practice
Before purchasing a property for house hacking, verify that the secondary suite is legal and permitted by checking with the local building department. If the suite is unpermitted, factor in the cost of bringing it up to code -- typically $20,000 to $50,000 for a full basement conversion in the GTA. Screen your basement tenant carefully since you will be sharing the property.
