On May 20, 2025, Vancouver City Council adopted the 2024 BC Building Code with Vancouver-specific provisions. The Building By-law 2025 (VBBL 2025) will generally come into effect on September 15, 2025, with delayed implementation for certain provisions as follows:
| Seismic design requirements (Part 4 and Part 9) |
The seismic design provision of the 2025 VBBL need not apply for building permits submitted before September 15, 2026.
Further consideration for deferral up to March 8, 2027, may be accepted by the Chief Building Official for an In-stream Project.

In-stream Project
An In-stream Project is a project that has submitted an acceptable application for rezoning or development permit before the effective date of the applicable regulation. Review Division C, Section 3.3 of the Building By-law for more details.
Adaptability in the 2025 Vancouver Building By-law
The 2025 Vancouver Building By-law (VBBL) generally maintains the same adaptability provisions as the 2019 VBBL.
These provisions have already been built into most residential units in Vancouver over the past decade, helping homes adapt more easily to the changing needs of residents.
In the first half of 2026, minor updates to these requirements are expected. These proposed changes will maintain our current adaptability approach while supporting greater densification and remaining compatible with modern residential unit design standards.
