Ontario’s 2024 Building Code: Updated Practice Tip on OBC’s Supplementary Standard SB-12 on Energy Efficiency for Housing
The 2024 edition of Ontario’s Building Code (O. Reg. 163/24) came into effect on January 1, 2025. As of April 1, 2025, all new permit applications will be reviewed using the 2024 OBC.
The new OBC references the 2020 National Building Code of Canada (NBC) for the harmonized parts of the code and the Ontario amendments document for the differences in the province. This change in legislation results in the need to update multiple OAA resources, including the updated OBC Data Matrices and PT.35 on Seismic Requirements.
End of the Transition Period
As the transition period for permit applications under OBC 2012 has ended, when Practice Tips are updated to reflect the OBC 2024 requirements, the previous versions will be withdrawn.
Access the updated Practice Tip PT.36.3 on OBC SB-12
The OAA’s Practice Resource Committee and OAA Council reviewed Practice Tip PT.36.3, OBC SB-12 Energy Efficiency for Housing –Prescriptive Compliance, which has been updated.
The Practice Tip PT.36.3 has undergone a significant update, not only to align with OBC 2024, but also to enhance the clarity of the content to provide practical and clear guidance in navigating through SB-12’s prescriptive compliance path.
