This project on Yore Rd in York, Toronto involved the design and permit approval for a three-unit residential building.
Cadaxx Design managed the entire process—from zoning review and concept layouts to BCIN-stamped permit drawings and coordination with structural and HVAC engineers.
The building replaces an older single-family home with a modern, efficient multi-unit dwelling that meets current Ontario Building Code and City of Toronto multiplex standards while blending with the existing residential streetscape.

Project Overview
The three self-contained units were organized to maximize natural light, privacy, and functionality within a compact footprint.
Each suite includes open-concept living spaces, a full kitchen, and independent HVAC and utility connections.
The design balances density and comfort, introducing much-needed rental housing in an established Toronto neighbourhood while maintaining architectural harmony with adjacent properties.
Zoning & Permit Coordination
Cadaxx Design conducted a comprehensive zoning review to confirm the project complied with Toronto’s multiplex by-laws for setbacks, height, and entrances.
Our team prepared the full permit set—architectural, structural, and HVAC—and responded promptly to examiner comments.
The building permit was issued without delay, demonstrating our efficient coordination and thorough understanding of multi-unit approvals in the city.
Construction Status
Completed – permit approved and construction finalized.
Timeline: approximately 10 weeks from submission to approval.
The Yore Rd apartment features a contemporary exterior with neutral brick, vertical cladding, and clean rooflines.
Large windows introduce abundant daylight, while recessed entries and balconies add depth and privacy.
The restrained palette complements the surrounding homes, creating a cohesive and timeless streetscape within the York community.
Inside, each unit was designed for functionality and comfort, featuring open living areas, modern kitchens, and durable finishes.
Light-toned walls and flooring enhance spaciousness, while independent mechanical systems ensure comfort and energy efficiency. The result is a bright, well-planned environment ideal for modern urban living in Toronto.

Only if the design exceeds zoning limits. Cadaxx prepares the drawings, rationale, and representation when variances are needed.
How long does it take?
Typical review times range from 6–12 weeks, depending on project scope and city workload.
What drawings are required?
Architectural, structural, and HVAC plans coordinated into one complete submission.
