Toronto
Property Type: Existing Single-Family Dwelling
Scope of Work: Conversion of 900 sq.ft. Unfinished Basement into Legal 2nd Residential Unit
Project Overview
This Toronto-based conversion project made strategic use of an existing 900 sq.ft. unfinished basement to create a spacious and modern 2-bedroom legal unit. While the basement was never finished, because it was part of the existing structure, we were able to apply Part 11 of the Ontario Building Code—allowing for reduced compliance requirements compared to Part 9. This move saved our investor both significant construction costs and project time while still meeting all health and safety standards.
The final design included a bright and open layout, premium finishes, and an emphasis on livability—making this unit highly attractive in the rental market.
Scope & Strategy
- Converted an existing 900 sq.ft. unfinished basement into a legal 2-bedroom unit.
- Utilized existing dedicated side entry as the primary exit.
- Applied OBC Part 11 provisions to reduce scope and cost of construction where applicable.
- Fire-rated all walls and ceilings separating the upper and lower units.
- Designed a full-size laundry room (not a closet) with proper appliances and laundry tub.
- Maximized natural lighting by proposing larger windows in key living areas.
- Used Part 11 to avoid overbuilding or unnecessary demolition, typical under Part 9.
- Maintained cost-efficiency without sacrificing code compliance or livability.
- Navigated fire separation and egress with ease thanks to a proactive design strategy.
- High-demand 2-bedroom unit created with smart cost-saving measures.
- Avoided unnecessary construction and delays by applying existing building provisions.
- Increased monthly cash flow potential without extensive modifications.
