Can You Renovate a Semi-Detached House in East York?
Short answer: Absolutely — but doing it right requires planning, permits, and the right expertise.
East York’s charming semi-detached homes — especially in Danforth-East York, Todmorden Village, and Broadview North — often date from the 1940s to 1960s. While full of character, these homes present unique renovation challenges due to shared party walls, outdated building materials, and older mechanical systems.
Whether you’re updating a kitchen or doing a full home renovation, it’s crucial to hire licensed professionals who understand these homes inside and out.
Before you begin:
Secure a signed party wall agreement with your neighbour.
Review local permit requirements (City of Toronto Residential Construction Permits).
Ensure your renovation plan addresses fire safety, sound control, and mechanical placement.
🔥 1. Fireproofing the Party Wall
In most East York semis, the party wall is simply a thin wood-frame division with little to no fire resistance. This means that if your neighbour’s home catches fire, your home could be at risk within minutes.
Best Practices:
Remove wall finishes down to studs during renovation.
Install fire batt insulation rated for party wall applications.
Use fire-rated drywall and seal all penetrations with fire caulk and tape.
Extend fireproofing through floor joist cavities, attic spaces, and basement ceilings where the party wall continues.

🔇 2. Soundproofing for Peace and Privacy
If you live in a semi-detached home, you already know — noise can travel through the party wall with surprising ease. Conversations, music, and even footsteps can feel uncomfortably close.
Our Recommendations:
Add sound attenuation insulation such as mineral wool.
Use resilient channels or sound isolation clips before drywalling.
Choose double-layer drywall with a sound-dampening compound.
Seal all edges and electrical box openings to reduce sound leaks.

🚫 3. Keep Mechanical Systems Out of the Party Wall
We often find dryer vents, drain pipes, and HVAC ducts running through party walls — a poor practice that can compromise both fire and sound performance.
Best Practices:
Relocate plumbing and ductwork away from the shared wall.
Limit penetrations to electrical wiring only.
Coordinate with your neighbour if their systems also pass through the party wall.
