Home Addition Framing Toronto — Licensed, Insured & 5-Star Rated

Addition framing costs in Toronto depend on the type of addition, total square footage, and structural complexity. Rear additions are typically the most straightforward to frame and the most cost-effective starting point. Second-floor additions carry higher costs because the existing foundation and first-floor structure may need reinforcement to carry the new load.

Garage conversions and in-law suites vary based on the scope of structural modification required. For an accurate number tailored to your Toronto project, contact Timberr Framing for a free written quote. We assess your plans and existing structure before pricing.

A standard rear addition frame typically takes one to two weeks. A full second-floor addition generally takes two to four weeks depending on size and complexity. Toronto-specific factors like permit timing and narrow-lot logistics can influence scheduling.

Timberr Framing provides a detailed project schedule during the quoting process so you always know what to expect.

In most cases, yes. The City of Toronto requires engineered drawings for any addition involving load-bearing modifications, new foundation work, or a second-storey build. This is part of the building permit process.

Timberr Framing works directly with structural engineers and coordinates throughout the project. We frame to the engineer's specifications and ensure the work is ready for inspection.

Yes — and this is where experience matters most. Many Toronto homes are 80 to 120 years old with balloon framing, rubble foundations, or non-standard lumber sizes. A poor tie-in between old and new creates structural and water-intrusion problems.

Timberr Framing specializes in structural tie-ins on older homes. We assess the existing framing, identify load paths, and connect the new structure properly — whether it is a rear bump-out on a Victorian or a second floor on a post-war bungalow.

Yes. Any home addition in Toronto requires a building permit from the City of Toronto before construction begins. This applies to second-floor additions, rear and side additions, garage conversions, and in-law suites. Heritage Conservation District overlays may add additional review steps in certain neighbourhoods.

Timberr Framing builds every addition to Ontario Building Code and ensures all work is inspection-ready. Permits are typically handled by the homeowner or GC — we frame to the exact specs your permit drawings require.

A home addition adds new square footage — a new room, new floor, or an extension. A renovation modifies existing space without changing the footprint, such as removing walls or refinishing a basement.

Timberr Framing handles both. For interior renovation framing, see our renovation framing services. For additions that expand your home's footprint, you are in the right place.

Yes. Ontario Building Code sets specific requirements for secondary suites including fire separation, sound transmission ratings, separate egress, and minimum ceiling heights. Every element of the framing must account for these requirements.
