This bulletin explains the impact of the transition to the 2024 Ontario Building Code on existing and proposed Certified Model Applications.
A Certified Model is a not a building permit and does not allow construction. Model certification ensures that plans meet the requirements of the version of the Ontario Building Code that was in place at time of certification. As such, we are providing helpful information and listing key dates to assist with the transition:
Existing Certified Models
Any models previously certified under the 2012 Ontario Building Code (as amended), are considered "substantially complete" and can be used in support of a complete Building Permit application until March 31, 2025.
Effective April 1, 2025, any Certified Models used in support of building permit applications will be required to comply with the 2024 Ontario Building Code.
Proposed Certified Models
Certified Model applications submitted in 2024 must comply with the 2024 Ontario Building Code regulations.
