Key considerations for Toronto
A structural assessment of the existing foundation, walls, and framing is required before design.
Floor Space Index (FSI) and lot coverage calculations must confirm the addition fits as-of-right.
Angular plane requirements limit the bulk of additions near property lines.
Full architectural drawings including new and existing floor plans, sections, and elevations are required.
