Home additions in Etobicoke are some of our busiest projects. Lot sizes in established Etobicoke neighbourhoods support rear and side additions that would not fit on smaller central Toronto lots, and the housing stock includes hundreds of post-war bungalows ready for second-storey additions. We have built rear additions in The Kingsway, two-storey additions in Mimico, and full second-storey additions on Alderwood bungalows.
Most Common Etobicoke Addition Projects
- Two-storey rear addition (400 to 800 sq ft). Adds kitchen and family room downstairs, primary bedroom upstairs. Most popular project type in Etobicoke.
- Full second-storey addition on a bungalow (800 to 1,200 sq ft). Doubles usable floor area on Alderwood, Long Branch and other post-war bungalows.
- One-storey rear addition (200 to 400 sq ft). Common when expanding a kitchen or family room without changing the upstairs.
- Side bump-out (50 to 100 sq ft). Often used to expand a kitchen or primary ensuite where lot setbacks allow.
- Heritage-respecting addition in The Kingsway. Brick-matched, roofline-respecting addition that often blends with original architecture.
Etobicoke Permit and Zoning Considerations
Etobicoke is part of the City of Toronto, so building permits and zoning bylaws are issued by the City of Toronto. Common Etobicoke zoning challenges:
- Lot coverage limits. Many established neighbourhoods cap lot coverage at 33 to 35 percent. Additions often push over this and require Committee of Adjustment.
- Side yard setbacks. Required side setback varies by zone; bump-outs often need a minor variance.
- Floor space index. Some zones cap total floor area as a ratio of lot area.
- Heritage Conservation Districts. The Kingsway and parts of Mimico fall within HCDs, requiring heritage permit approval for visible exterior work.

What an Etobicoke Client Recently Said
"Had a second-floor addition done on our bungalow in Etobicoke. The structural work was complex but they managed the whole process including permits. Added 800 sq ft and it looks like it was always there." - James T., Etobicoke
