Frequently Asked Questions About Renovating in Rosedale
Do I need Committee of Adjustment (CofA) approval to renovate in Rosedale?
Most major projects in Rosedale require CofA approval, especially if you’re adding floor space, raising a roofline, or expanding lot coverage. While permitting and applications are handled by your architect, Lighthaus Built works closely with your design team to help manage the process from a construction perspective — ensuring that what’s proposed is both practical to build and aligned with your project goals.
Can a heritage home in Rosedale be modernized?
Yes — but updates must respect the home’s historic character. Our team specializes in heritage renovations, replicating architectural details while introducing modern layouts, finishes, and systems that improve everyday living.
Do I need an arborist report to build or renovate in Rosedale?
In many cases, yes. Rosedale’s tree canopy is protected by city bylaws, and construction often requires arborist reports and tree protection zones. We coordinate these requirements to keep your project compliant.
How long does a Rosedale renovation take?
Timelines depend on the scope of work and approvals. Whole-home renovations typically take 8–12 months, while additions or basements may range from 6–9 months. Pre-construction planning ensures your schedule is realistic and efficient.
What does a Rosedale renovation or addition typically cost?
Every project is unique, but Rosedale renovations generally cost more than other neighbourhoods due to heritage requirements, approvals, and lot logistics. Download our free Toronto Renovation Cost Guide to get a clearer picture of budgets.
