Completed a major renovation on our 1906 Roncesvalles semi last year. Sharing the heritage-specific aspects since I found very little practical info about renovating in this area before we started.
The heritage context:
Our street is within the Roncesvalles-Howard Park-Garden Avenue Heritage Conservation District (HCD). This means any exterior changes require a Heritage Permit in addition to a building permit.
What needed heritage approval:
- Front window replacement (they approved our choice of double-hung wood-effect vinyl — exact profile specifications were reviewed)
- Rear addition (full heritage permit + minor variance from CoA for rear setback)
- Restoring original porch (actually easier than we expected — they appreciated that we were restoring rather than removing)
The heritage permit process:
- Application submitted with photos of existing conditions and drawings of proposed changes
- Heritage Preservation staff reviewed and responded within 6 weeks
- One round of comments (wanted minor changes to window profile dimensions) — easy fix
- Full approval on resubmission
Surprises:
- The heritage review was less onerous than we feared — they really just want the exterior character maintained
- Interior changes (removing walls, kitchen/bath renovation) required NO heritage approval — it’s only exterior
- Our architect had heritage experience which made the application process much smoother
Cost premium for heritage compliance:
The wood-effect vinyl windows cost about $200 more per window than standard vinyl. Essentially nothing in the context of the project.
Happy to answer questions about navigating HCDs in Toronto.
