The 2024 edition of Ontario’s Building Code (OBC) came into effect on January 1, 2025, with a three-month transition period until March 31, 2025 for permit applications under the 2012 OBC for which the working drawings were substantially complete before 2025. Then, on April 1, 2025, all permit applications will be reviewed using the 2024 OBC.
With the announcement from Ministry of Municipal Affairs and Housing (MMAH) in 2024 of a new edition of Ontario’s Building Code, the OAA started working on technical updates needed to various documents, particularly with respect to the introduction of the new Part 2 Farm Buildings and Agricultural Occupancy (Group G) and its consequential amendments to the Architects Act.
Normally, there is only one version of a Practice Tip current at any given time. However, during the transition period, there will be both an old and an updated version of Practice Tips PT.3 and PT.35, which are current.

Over the next couple of months, other peripheral resources located in the OAA’s Practice Advisory Knowledge Base may be updated to align with Ontario’s new Building Code. Stay tuned for future updates in the OAA Practice Advisory newsletter or on the OAA Website.
