Common Questions
How much does a multiplex cost to build in Toronto?
A triplex runs $400K-$1.1M CAD, a fourplex $500K-$1.4M and a sixplex in approved zones $800K-$2M. Converting an existing house costs $250K-$900K. New builds work out to roughly $320-$520 per sqft, conversions $220-$380 per sqft, before any luxury finish uplift of $80-$150 per sqft. Your lot width, foundation, finish level and whether the building falls under OBC Part 9 or Part 3 move the number inside those bands, which is why we confirm zoning and unit count in a written feasibility report before quoting a fixed price.
Is a sixplex permitted anywhere in Toronto?
No. The 2025 sixplex amendment applies only in the Toronto and East York District and Scarborough Ward 23 North. Everywhere else in the city, fourplex is the as-of-right maximum under EHON, so we verify your parcel before any design work. If a builder pitches six units on a North York, Etobicoke or York lot, ask them to show the zone confirmation in writing.
How long does a fourplex take from zoning to occupancy?
Plan on 1-2 weeks for feasibility, 6-10 weeks for design, 9-14 weeks for permit coordination and 9-12 months of construction. A Committee of Adjustment variance adds 4-6 months, which is why we confirm it is needed before design is final. Our Leslieville fourplex went from feasibility to occupancy in 11 months, including a side-yard variance.
What is the first step?
Book a written feasibility assessment ($1,500-$4,500). We pull your parcel zoning from GeoWarehouse, test the unit count against setbacks and height, screen heritage, trees and servicing, and give you a CAD budget range in 1-2 weeks. You walk away with a report you can take to a lender, even if you decide not to build with us.
