2024 Ontario Building Code

Ontario’s new 2024 Building Code (OBC) comes into effect January 1, 2025, and there are challenges in how various municipalities in Ontario are addressing the transition period between the 2021 OBC and the 2024 OBC.

Transition Rules and Application for Permit

Under the direction of the Chief Building Official for the City of Greater Sudbury, this municipality will be observing the transitional period for the implementation of the 2024 OBC with the following considerations:

For permits applied for during the transition period of January 1st, 2025, to March 31st, 2025, applicants requesting review under the 2012 OBC can provide a letter indicating that "working drawings were substantially complete as of Dec 31, 2024, and have been designed to conform with OBC 2012". Building Services will then review drawings under OBC 2012. If there is no accompanied letter, we will review under OBC 2024.

Effective April 1, 2025, all plans review will be under OBC 2024.

Key Transition Dates

May 22 – December 31, 2024 - All projects submitted for building permit must conform to current 2012 OBC, as amended.

April 10, 2024 - Release of the new building code.

January 1, 2025 - All projects submitted for building permit must conform to the 2024 Building Code.

Up to March 31, 2025 - Projects having working drawings substantially completed prior to January 1, 2025 can still apply under the 2012 OBC.

April 1, 2025, and Onward - All projects submitted for building permit must conform to the 2024 Building Code.

We hope that our approach will allow us to support our stakeholder groups as they work through the transition period and continue to deliver services that you have come to know.
