You’ve watched Toronto’s housing market evolve. You know that single-family homes with basements and unused square footage are no longer living up to their full potential. And you’ve probably heard that you can now legally turn your property into a fourplex or even a six-unit dwelling — but aren’t sure how to actually make it happen.
Multi-unit conversions are one of the most efficient ways to turn underused space into consistent, long-term income. Done right, they can more than double your rental revenue, increase property value by hundreds of thousands of dollars, and position you to take advantage of CMHC-backed financing and waived development charges. But if you’ve looked into the process, you already know that it’s not simple. The rules are evolving. The paperwork is dense. And the last thing you want is to get halfway through a build only to be stopped by a code violation or permit delay.
BUILD WEALTH, STRATEGICALLY.
Yes, you can — and in most areas of the city, it’s now easier than ever. Recent zoning changes allow for up to four residential units in most low-rise neighbourhoods, with some properties eligible for six depending on configuration. The key is meeting the technical and regulatory requirements, which we’ll assess for you at the outset.
That depends on your lot, your existing structure, and your goals. In many cases, homeowners are converting unused basements into legal apartments, dividing homes into upper and lower flats, or reconfiguring large single-family layouts into two, three, or four self-contained dwellings. We help you understand what’s feasible and make sure the layout complies with building codes and fire safety regulations.
Costs vary significantly depending on the scope of work, the number of units, and the condition of your existing home. A straightforward duplex conversion may start around $150,000, while more extensive fourplex or six-unit conversions can reach $400,000 or more. We provide detailed estimates based on your site and the kind of outcome you’re looking for — and we help you budget with clarity, not guesswork.
In most cases, no. Toronto’s updated bylaws now allow multi-unit conversions “as of right” in many zones, meaning you don’t need a zoning variance as long as you follow the rules. You will, however, need a building permit, architectural drawings, and inspections throughout the process. We handle all of that on your behalf.
It can. Multi-unit properties are often assessed differently than single-family homes, and that may influence your property tax bill. On the upside, the added rental income can strengthen your financing position and potentially qualify you for CMHC-backed programs like MLI Select, which offer preferred terms for multi-unit dwellings. We work with partners who can help you navigate financing and tax planning to make sure the numbers work in your favour.
Absolutely. Many homeowners convert part of their property into income-generating rental space while continuing to live on-site. Whether you want to downsize within your home, create a suite for family, or build in flexibility for the future, we’ll help you design a layout that balances privacy, comfort, and value.
