Public review Spring 2026The Canadian Board for Harmonized Construction Codes (CBHCC) is inviting code users, interested parties, and the broader public to take part in the first public review of the 2030 code cycle.

Proposed changes to the National Model Codes in this review address modular construction compliance and prescriptive compliance for Energy Performance Tier 2, among other key topics, including:

  • Accessibility
  • Airtightness
  • Automatic sprinkler systems
  • Drainage systems
  • Fire protection
  • Heating, ventilating, and air conditioning (HVAC) systems
  • Plumbing materials and equipment

The public review runs from April 27 to June 22, 2026. Those interested in participating in the review can access the proposed changes on the CBHCC website and provide feedback.

The public review gives Canadians and interested organizations a chance to help shape the National Model Codes. After the review, comments will be assessed by the relevant code development committees and recommendations on the proposed changes will be made to the CBHCC. Approved changes will be included in the 2030 editions of the Codes, which provinces and territories may adopt or adapt into their regulation.
