Building Smarter in the Sea-to-Sky: 2025 Step Code Changes in Whistler, Squamish & Sea to Sky corridor
If you’re planning a custom home or renovation in Whistler, Squamish, or Sea to Sky corridor, you’ve likely heard about the evolving BC Energy Step Code and Zero Carbon Step Code. These regulations are reshaping how homes are designed and built across the Sea-to-Sky corridor—pushing toward higher efficiency, lower emissions, and better long-term performance.
At All Mountain Contracting, we work closely with homeowners, developers, and consultants to ensure every project meets—and often exceeds—these new standards. As a trusted general contractor in Whistler and Squamish, staying ahead of building code changes is a key part of delivering successful, future-ready homes.
What Changed in the 2025 BC Building Code?
As of March 10, 2025, updates to the BC Building Code now require all new homes to meet Step 3 of the BC Energy Step Code as a minimum standard.
In practical terms, this means:
Improved insulation and building envelope performance
High-performance windows and doors
Increased airtightness (verified through testing)
Reduced energy consumption for heating and cooling
In addition, new requirements include:
Operational carbon tracking (measuring emissions once the home is in use)
Enhanced seismic (earthquake) standards
Improved accessibility design considerations for long-term adaptability
For homeowners building in the Sea-to-Sky region, this results in homes that are not only more efficient—but also more durable, comfortable, and future-proof.
How Step Code Requirements Differ Across the Sea-to-Sky
While the provincial baseline is now Step 3, municipalities like Squamish, Whistler and Pemberton are taking different approaches.
Squamish: Leading the Way in Zero-Carbon Building
The District of Squamish has positioned itself as a leader in sustainable construction.
As of July 2024, Zero Carbon Step Code EL-4 is required
New homes must be designed to operate on clean energy (primarily electric)
Energy advisors must be involved before construction begins
This has a direct impact on how we approach home building in Squamish, from early design through to mechanical system selection.
Pemberton: High Efficiency Standards Since 2021
In Pemberton, builders have been working to Step 4 energy requirements for several years.
This includes:
Pre-construction energy modelling
Blower door testing during and after construction
Higher-performing building envelopes
For clients, this translates into homes that are exceptionally efficient and comfortable year-round.
Whistler: Evolving Toward Stricter Standards
Whistler is currently reviewing its building bylaws and is expected to move toward stricter energy and carbon requirements in the near future.
At present:
Most projects align with provincial Step 3 requirements
Future updates will likely mirror Squamish and Pemberton
As an experienced home builder in Whistler, we proactively build with these upcoming changes in mind—helping clients stay ahead of future regulations.
Sea-to-Sky Rural Areas (SLRD)
The Squamish-Lillooet Regional District (SLRD), including areas like Britannia Beach and Lillooet Lake, generally follows the provincial baseline.
Step 3 energy efficiency is required
Energy modelling and testing are still part of the process
Fewer zero-carbon mandates (for now)
What This Means for Homeowners
For anyone planning a renovation or custom home in Whistler, Squamish, or the Sea-to-Sky corridor, these changes bring major benefits:
✔ Lower Operating Costs
More efficient homes mean reduced heating and cooling bills over time.
✔ Improved Comfort
Better insulation and airtightness create consistent indoor temperatures year-round.
✔ Healthier Living Environments
Improved ventilation systems lead to better indoor air quality and reduced moisture issues.
✔ Increased Property Value
Energy-efficient homes are in high demand and often command stronger resale value.
What This Means for Builders (And Why It Matters Who You Hire)
From a construction standpoint, these changes add complexity:
More coordination with energy advisors
Additional testing and verification steps
Greater focus on detailing and workmanship
More planning required at the design stage
This is where working with an experienced general contractor in the Sea-to-Sky region becomes critical.
At All Mountain Contracting, we integrate energy compliance, scheduling, and communication into every phase of the project—ensuring nothing is missed, and everything runs smoothly from permit to completion.
The Shift Toward Net-Zero Homes
These Step Code updates are part of a bigger picture.
By 2032, all new homes in BC are expected to be net-zero energy ready
By 2050, Canada aims for near-zero emissions in new residential construction
For homeowners, this means building decisions made today will directly impact long-term performance, operating costs, and environmental impact.
Building Smarter in the Sea-to-Sky
The Sea-to-Sky corridor is quickly becoming one of the most progressive regions in BC for sustainable construction. Municipalities like Squamish and Pemberton are already leading the way, while Whistler continues to evolve.
For homeowners and developers, the takeaway is simple:
Building smarter isn’t optional anymore—it’s the new standard.
At All Mountain Contracting, we specialize in delivering high-performance renovations and custom homes in Whistler, Squamish, and across the Sea-to-Sky corridor. Our approach ensures every project is built to meet today’s codes—and tomorrow’s expectations.
