On February 17, 2023, the OAA submitted selective comments in response to Canada Standards Association's (CSA) Public Review of CSA Z252 Volumetric Modular Construction - Guide to Compliance and Approval Processes (New Standard). The submission leveraged the experience of the OAA members, as well as providing additional clarity regarding roles and responsibilities of different stakeholders involved in this type of project.

This new proposed Guide focuses on the inspections and approvals processes followed by the authorities having jurisdiction (AHJs) that evaluates the compliance of the modular building for construction and occupancy. These guidelines are intended for construction and inspection of partially or fully enclosed permanent modular buildings of any size and occupancy. The guide serves as a supplement to CSA A277 Procedures for Factory Certification of Buildings and CSA Z250 Process for Delivery of Volumetric Modular Buildings.

OAA members were also encouraged to respond to the proposed public review through the OAA News (January 20 edition) as well as the Facebook social media platform on February 7, 2023.
