Basement Renovation in Downtown Toronto, Ontario
Downtown Toronto's Victorian rowhouses, century-old semis, and mid-rise condos sit atop some of the most underutilized square footage in the city. Whether your basement dates back to the 1900s in Cabbagetown or you're finishing a raw utility space in a newer King West condo building, we help you convert it into a livable, income-generating, or simply stunning extension of your home.

Frequently Asked Questions About Downtown Toronto Basement Renovations
Answers to the questions we hear most often from Toronto homeowners considering a basement finishing or renovation project.
In Downtown Toronto, basement renovation costs generally fall between $35,000 and $80,000+, varying based on square footage, the age of your home's existing infrastructure, and the level of finish selected. A straightforward open-concept space typically starts near $25,000, whereas a fully equipped basement suite with a separate entrance, kitchen, and premium finishes can run well beyond $100,000. Every project receives a free, detailed, itemized quote.
Most standard basement finishing projects in Toronto are complete within 6–10 weeks. However, older homes—especially those built before the 1960s—sometimes require additional prep work such as underpinning, foundation repairs, or updated electrical panels, which can extend the timeline to 12–16 weeks. We build a realistic schedule into your quote from day one so you always know what to expect.
Yes—the City of Toronto requires a building permit for virtually any basement work involving framing, mechanical systems, plumbing, or electrical upgrades. We manage the entire permit application and inspection process on your behalf as a standard part of every project, so you never have to navigate Toronto Building's portal on your own.
Absolutely. Toronto's zoning bylaws now permit secondary suites in most residential zones, making basement apartments a highly viable investment in neighbourhoods like the Annex, Leslieville, and Roncesvalles. We build fully legal units that satisfy Ontario Building Code requirements—separate entrances, fire separations, minimum ceiling heights, egress windows, and all required safety measures—so your unit passes inspection and commands strong rental rates.
Moisture management is especially critical in Toronto's older housing stock, where original stone or brick foundations were never designed with modern below-grade living in mind. Before any finishing begins, we conduct a full moisture inspection and hydrostatic assessment. Solutions range from interior drainage membranes and sump systems to exterior waterproofing where needed, always using mould-resistant framing and insulation materials throughout.
Downtown Toronto homeowners use finished basements for everything from rental income suites and home offices to private gyms, family recreation rooms, home theatres, wine cellars, guest bedrooms, and nanny suites. We design around your specific lifestyle—whatever you need most from the space, we'll build it to suit.

What Downtown Toronto Homeowners Say About Our Basement Renovations
"We have a Victorian semi in Trinity Bellwoods with a basement that had been sitting empty for years—stone foundation, low ceiling, the works. Peace of Mind transformed it into a legal rental unit with a proper bedroom, full bathroom, and separate side entrance. The permit process was handled entirely by their team and the finish quality exceeded what we'd hoped for."
"Our row house in Cabbagetown had the original 1920s fieldstone walls, and we were nervous no contractor would take it on. Not only did Peace of Mind handle the waterproofing and framing around the old foundation, they built us a stunning home office and media lounge. It's easily the nicest room in the house now."
"We needed a basement gym and a quiet home studio in our Leslieville townhouse, and the team delivered both within a tight footprint. The soundproofing between floors is impressive, the LVP flooring looks fantastic, and they came in on budget. I'd recommend them to anyone in the east end without hesitation."
