Construction is an act of trust. Following the OBC 2024 is how we honour that trust. Disclaimer: This article provides general information and does not constitute legal or professional engineering advice. Always consult a licensed professional and your local municipality for site-specific compliance with the Ontario Building Code 2024.
The Ontario Building Code (OBC) is the regulatory bible for construction in Canada’s most populous province. It dictates how buildings are designed, constructed, renovated, and demolished. As of 2024, Ontario is undergoing a significant regulatory shift, moving toward a more harmonized system with the National Building Code while also introducing stringent energy efficiency and accessibility requirements.
“Small buildings (sheds, garages) are exempt.” Fact: Detached garages under 10 sq.m. (108 sq.ft.) are exempt, but any garage with heating or a door connected to the house triggers CO alarm requirements.
