The Canadian Board for Harmonized Construction Codes (CBHCC) has released the 2025 editions of the National Model Codes which bring forward new revisions but some provinces – such as BC – have already implemented new standards or have outstripped the current codes. “The 2025 National Model Codes aim to create a harmonized framework that addresses building safety, accessibility, energy efficiency and climate adaptation,” said Silvia Garcia, co-chair of the CBHCC. The 2025 National Model Codes include the National Building Code (NBC), National Energy Code, National Plumbing Code and National Fire Code. …BC‘s building code (BCBC) allowed 18-storey encapsulated mass timber construction (EMTC) in 2024 with Ontario joining in a year later. The 2020 NBC set the structures at 12 storeys and 42 metres in height while the new 2025 NBC code retains the 12 storeys (for residential or Group C structures and office occupancies or Group D) but raises the height to 50 metres.
