Kenilworth Ave | 03 Unit Conversion

Hamilton

Property Type: Existing Single-Family Detached Home
Scope of Work: Full Conversion to Legal Triplex (One Unit per Floor)

Project Overview:

Located in Hamilton, this project focused on converting an existing single-family home into a fully compliant 3-unit legal triplex, with one self-contained residential unit on each level: basement, ground, and second floor. The design optimizes each floor’s unique features while ensuring full Ontario Building Code and fire safety compliance.

Thanks to Hamilton’s updated zoning bylaws, no additional parking was required for this triplex—a major benefit that allowed the investor to proceed without costly site plan changes.

Scope & Strategy:

• Designed three legal units, each with independent      living, kitchen, bathroom, and egress:

  • Basement Unit: Slightly reduced in       size to accommodate a shared laundry room

  • Ground Floor Unit: Full layout       optimized for rental-ready functionality

  • Second Floor Unit: Enhanced with access       to the existing attic, providing added storage space

• Retained 1 existing parking space in line with      Hamilton’s current zoning exemptions for triplexes

• Ensured OBC compliance on fire separation, sound transmission,      and mechanical ventilation

• Incorporated natural lighting and egress strategies without      requiring new window openings

Challenges Solved:

• Fire protection for exit paths:

  • Installed fire shutters on windows along tenant exit       routes

  • Installed 5/8" Type X drywall over existing exterior       masonry walls to increase fire resistance along key egress paths

• Navigated ceiling height and headroom clearances in basement      with smart layout planning

• Maximized layout efficiency without triggering full building      upgrades or costly additions

Investor Benefits:

• Transformed a single-family home into a cash-flowing legal      triplex with three rental income streams

• Increased building value significantly with minimal site      alterations

• No additional parking required under Hamilton’s progressive      zoning changes

• Added tenant appeal with attic-based storage and well-separated      units

• Fully permit-approved and compliant

Current Status:

Permit approved. Construction completed. Property is now operating as a fully legal 3-unit residential building.
