Ontario CodeNews Issue 381: Consultations

1. Consultation on Proposed Changes to Part 8 "Sewage Systems" of the Building Code

The Ministry of Municipal Affairs and Housing has posted notices on the Environmental Registry of Ontario and the Regulatory Registry to propose changes to the Building Code related to Combined Treatment and Dispersal Systems. The proposal is available on the Environmental Registry of Ontario ero.ontario.ca/notice/026-0577 and the Regulatory Registry www.regulatoryregistry.gov.on.ca/proposal/54175 for comment until June 26, 2026.

2. Consultation Supporting Development of Four-Storey Townhouses

The Ministry of Municipal Affairs and Housing has posted a notice on the Regulatory Registry regarding targeted amendments to Part 3 of the Ontario Building Code to support the construction of four-storey, non-stacked, townhouses in Ontario.

To date, four-storey townhouse projects have required the use of Alternative Solutions to address fire and life safety requirements. The proposed amendments would remove design constraints and enable this building type to be constructed without the need for Alternative Solutions, while maintaining fire and life safety standards.

The proposal is available on the Regulatory

Registry www.regulatoryregistry.gov.on.ca/proposal/54175 for comment until June 26, 2026.

Public consultations will be held to provide an opportunity for further discussion. If you would like to participate in these discussions or would like more information on the consultations, please contact buildingcode.consultation@ontario.ca.
