  • Early adoption of the National Building Code requirements for encapsulated mass timber to enable the construction of 12-storey tall wood buildings in specific jurisdictions;
    • Accompanying changes to the BC Fire Code are proposed and anticipated to available soon.
  • New carbon monoxide detector and alarm requirements for stores, offices, classrooms, churches, and recreational facilities;
  • Preliminary Energy Step Code requirements for hospitals, schools, community centres, and university/college classrooms have been introduced, and requirements for residential and office buildings have been refined, to support the CleanBC commitment;
  • Increased requirements for lighting in recycling rooms; and
  • Additional requirements for fire alarms and exits to increase safety on occupied roofs.

The online BC Building Code 2018 will be updated to reflect the Revision 2 changes.
