Multiplex & second-unit brief: duplex/triplex/fourplex and laneway builds
For plumbing, HVAC, electrical, fire-separation, kitchen/bath, appliance and finishing trades.
Toronto's multiplex wave means many new 2-4 unit builds. Each unit multiplies plumbing, mechanical, electrical and finish scope.
When to act: Permit issued: framing and rough-in trades are being booked. Trades already filed are shown so you can see what is still open.
292 matching permits (issued in the last 30 days, or applications in review) in the City of Toronto; 8 are shown, researched projects first. The paid brief includes every match, filtered to your service area, delivered weekly with company contact paths researched where a developer or builder is identifiable.
