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

Addition framing costs in Scarborough are driven by the project type, square footage, and structural complexity. Rear additions are generally the most cost-effective option. Second-floor additions — especially on split-level homes — cost more because of the structural work required to integrate new framing with staggered existing floor levels.

Garage conversions and in-law suites vary with scope. For a reliable number, contact Timberr Framing for a free detailed quote tailored to your Scarborough project.

A standard rear addition frame typically takes one to two weeks. A full second-floor addition on a split-level or detached home generally requires two to four weeks depending on size and complexity.

Timberr Framing provides a clear project timeline during the quoting process and maintains communication throughout the build.

In most cases, yes. Any project involving load-bearing changes, foundation work, or a second-floor build requires structural engineering. This is especially true for additions on split-level homes, where the staggered floor system adds complexity.

Timberr Framing coordinates directly with structural engineers and frames to their specifications. We ensure the structure meets all requirements for municipal inspection.

Yes — and this is an area where our experience matters. Split-levels and side-splits have staggered floor levels and non-standard rooflines that make additions more complex than a typical bungalow or two-storey build.

Timberr Framing has direct experience framing additions on these home types. We assess the existing structure, work with your engineer to plan the tie-in, and frame the addition so it integrates cleanly with the original design.

Yes. Any home addition in Scarborough requires a building permit from the City of Toronto before construction begins. This applies to all addition types — second-floor builds, rear extensions, side additions, garage conversions, and in-law suites.

Timberr Framing frames to Ontario Building Code and delivers work that is inspection-ready. Permits are typically handled by the homeowner or their GC — we frame to the approved drawings.

A home addition expands your home — adding new rooms, a new storey, or an extension. A renovation modifies existing space without increasing the home's overall size.

Timberr Framing does both. For renovation framing, visit our renovation framing services page. For additions, you are in the right place.

Yes. Ontario Building Code has specific standards for secondary suites — fire separation, sound transmission ratings, separate egress, and minimum ceiling heights. Every aspect of the framing must be built to these standards.

Timberr Framing delivers secondary suite framing to code — including fire-rated wall assemblies, sound isolation framing, and proper egress window framing. All work is left inspection-ready.
