BC Building Code Changes Affecting Commercial Roofing in 2026
The 2026 BC Building Code introduces the most significant changes to commercial roofing requirements in over a decade. New energy efficiency standards, updated seismic design requirements, and enhanced accessibility provisions will affect virtually every commercial roofing project starting January 1, 2026.
For commercial building owners, these changes represent both opportunities for improved building performance and challenges for compliance planning. Projects initiated before the deadline may continue under current code provisions, but new permits require full 2026 compliance.
