Are Vancouver’s New Building Code Changes Going to Affect My Renovation?

And what you really need to know before filing permits in late 2024 or 2025

The Short Answer? It Depends on Your Timeline and Project Scope

If you're planning a major renovation or custom home build in Vancouver (or anywhere in BC), the 2024 updates to the BC Building Code might already be on your radar. But how much they’ll affect your project depends on when you file your permit and what you're renovating.

Two of the biggest changes taking effect in March 2025 include:

• New adaptable dwelling standards
• Updated seismic design requirements

Let’s break down what’s changing, who it applies to, and how Square One can help you stay ahead.

What’s Actually Changing?

1. Adaptable Dwelling Unit Requirements (March 10, 2025)

If you’re building a new multi-unit home (think: duplex, triplex, laneway), certain units must be built to be adaptable—meaning they can be easily modified for aging in place or improved accessibility.

This includes:

• Clearances around toilets, showers, and entryways
• Reinforcements for future grab bars
• Lower thresholds and wider doors

Important: These requirements generally apply to new construction, not small renovations. But if you’re converting your home into a suite or adding a unit, it’s worth confirming how these rules might apply.

2. New Seismic / Earthquake Design Provisions (March 10, 2025)

New builds and major structural upgrades will also need to comply with updated seismic standards, including:

• Revised design loads
• More prescriptive framing and connections

These changes aim to improve earthquake resilience across BC homes, but they may add time, cost, and complexity—especially for hillside builds or laneway homes.

3. The Overheating Rule (in effect since March 8, 2024)

As of this year, all new builds (and some major renos) must ensure at least one living space in the home doesn’t exceed 26°C during peak summer conditions without relying solely on A/C.

That means designers and builders must consider:

• Passive cooling strategies (e.g. shade, ventilation, window orientation)
• Effective insulation and building envelopes
• Mechanical cooling when needed

This new rule is BC’s way of responding to extreme heat events without making every home dependent on air conditioning.

Timing Is Everything: “In-Stream” Protection

Here’s the good news: If your permit is filed before March 10, 2025, your project may be protected under the older (2018) building code.

That means:

• You might not need to meet the new seismic or adaptability rules
• Your project may be simpler, faster, and more cost-effective
• But you still need to comply with overheating rules, which are already in effect

If you're planning a laneway, addition, or full gut renovation, getting your design and permit process started soon could save you thousands.
