The Ministry of Municipal Affairs and Housing (MMAH) has released a digital version of the two-volume English 2024 Ontario Building Code (OBC) Compendium. Use this link to request a free copy online today. A hard copy of the 2024 Building Code Compendium is still in development and will be made available through Publications Ontario. You can sign up to be notified when the binders are in stock here. Note that Building Code exams will continue to use the 2012 Building Code provisions until a later date, to be confirmed by MMAH. 

OHBA is committed to supporting our members through this transition. We are continuing to work closely with MMAH and other key partners to coordinate follow-up training around the 2024 OBC. We look forward to announcing more information about updates and training in the coming months!

As a reminder, to ease the implementation of the new Building Code, MMAH has provided a transition period for code users. The 2024 OBC has an in-effect date of January 1, 2025, with a further three-month transition period until March 31, 2025, for building permit applications for which the working drawings were substantially complete before January 1, 2025. 

If you have any immediate questions or concerns about this, please contact OHBA's Miyoko Oikawa.
