Canniff Place | 02 Unit Conversion
Kingston

Property Type: Single-Family Backsplit | ~1,985 sq. ft.
New Unit Layout: 2 Bedrooms | 1 Bathroom | Legal Basement Suite
Project Overview:
This project focused on transforming the finished basement of a 1985 sq. ft. backsplit dwelling into a legal 2-bedroom, 1-bathroom secondary suite. With the majority of the basement already developed, our approach centered on reconfiguring internal layouts to meet Ontario Building Code requirements—allowing the homeowner to add a fully compliant income-generating unit without extensive structural work.
Scope & Strategy:
Reconfigured existing finished basement to accommodate 2 bedrooms, a bathroom, living area, and kitchen space
Upgraded fire separations, soundproofing, and egress to comply with OBC secondary suite standards
Maintained existing services where possible to reduce construction cost and timeline
Ensured proper access and privacy between upper and lower units (dependent on existing entry layout)
Challenges Solved:
Achieved legal compliance through minimal rework—preserving most of the existing basement finishes
Strategically restructured room layout to meet minimum bedroom size, ceiling height, and natural light requirements
Delivered permit-ready drawings with streamlined review due to limited scope of change
Investor/Homeowner Benefits:
Added a legal 2-bedroom unit with minimal investment
Ideal for generating passive rental income or supporting multi-generational living
Retained full use and visual integrity of the main dwelling while boosting property value
Current Status:
Permit approved. Construction completed!
