Build or Convert Your Property Into a Legal Multi-Unit Income Property

A multiplex conversion is the process of converting a single-family home into a legal duplex, triplex, or multi-unit residential property. This involves structural modifications, fire separation systems, separate entrances, and code-compliant construction supervised by a licensed general contractor.

Yes. Duplex and multiplex conversions require zoning review, building permits, inspections, and compliance with fire and safety regulations. Our general contractor team manages permit applications, engineering coordination, and inspections to ensure your property meets all legal requirements.

The cost of a multiplex conversion depends on layout changes, structural work, servicing upgrades, fire separation requirements, and finish selections. Basement suite conversions are typically less complex, while triplex or fourplex conversions require larger structural and mechanical upgrades. We provide a detailed scope and transparent estimate before construction begins.

Project timelines vary based on permitting, design approvals, and construction scope. The planning and permit phase typically takes 2–4 months, followed by a construction phase of 4–6 months depending on scope. As your general contractor, we provide a defined schedule once project requirements are confirmed.

Legal duplex and multiplex conversions require fire-rated assemblies, proper egress, interconnected smoke alarms, and sound separation between units. We coordinate engineering and code-compliant construction to ensure all safety standards are met.

The first step is scheduling a consultation to assess zoning eligibility, property layout, and conversion feasibility. We review your goals, outline potential unit configurations, and develop a preliminary scope. Once approved, our licensed general contractor team manages planning, permits, and full construction through completion.

Yes. New multi-unit construction requires zoning approval, building permits, and engineered drawings before construction can begin. Requirements vary by municipality, but typically include site plans, fire separation design, and servicing approvals. Our team manages the full permit process to ensure your project meets all local building code and zoning requirements.

The cost of new multi-unit construction depends on factors such as lot conditions, number of units, design complexity, and servicing requirements. In the GTA, projects can range from several hundred thousand to over $1M+. We provide detailed estimates based on your property and development goals to ensure accurate budgeting from the start.

The timeline for new multi-unit construction depends on zoning approvals, permits, and project complexity. The planning and permit phase typically takes 3–6 months, followed by 6–12+ months of construction depending on the size and number of units. A detailed schedule is provided once design, approvals, and scope are finalized.
