OBC-Compliant Residential Floor Plans: Key Code Touchpoints

Stair dimensions, egress, smoke alarms, and spatial clearances that residential plans must address under the Ontario Building Code.

Residential renovations and new builds must demonstrate compliance with the OBC through plan annotations, sections, and coordinated details—not just room layouts.

Stair rise/run, guard heights, window areas for bedrooms, and ceiling heights in basements are frequent review items.

Renovations vs. new construction

Renovation projects often trigger mixed compliance paths depending on extent of work. Accurate as-built documentation is essential before proposing changes.

New construction allows more flexibility in layout but requires complete energy and structural coordination with other consultants.
