Vancouver Step Code Requirements
Current Step: 3+ (VBBL exceeds provincial minimum) | ACH Target: 2.5 ACH50 or better | Climate Zone: 4 | HDD: ~2,925 | Permit Office: vancouver.ca/building
Current Requirements
The City of Vancouver operates under the Vancouver Building By-law (VBBL), which is a separate legal instrument from the provincial BC Building Code and routinely sets a higher bar. Vancouver adopted the Zero Emissions Building Plan in 2016, set a target of zero emissions for all new buildings by 2030, and has been ratcheting energy and carbon requirements every two to three years since.
For Part 9 residential buildings, Vancouver currently requires Step 3 as the minimum airtightness and energy performance level, layered with near-zero greenhouse gas intensity (GHGI) limits for space and water heating. The combined effect is that a Step 3 home in Vancouver looks very different from a Step 3 home in Kelowna or Kamloops, even though both technically reference the same BC Energy Step Code framework. Vancouver’s overlay on top of Step Code is the part that catches out-of-town builders most often.
Key Differences from Provincial Step Code
- Zero emissions framework on top of Step Code: Vancouver’s requirements treat energy efficiency and carbon emissions as separate compliance dimensions. Hitting Step 3 on the energy axis is not enough on its own; the GHGI limit must also be met, which in practice rules out gas-based space heating in most new builds.
- Electric heating de facto required: New Part 9 residential construction is effectively required to use electric heat pumps for primary space heating, since the GHGI limits cannot be met with conventional gas furnaces. Cold-climate air-source heat pumps are the dominant compliance path.
- Climate Zone 4 advantage on the energy side: Vancouver’s milder climate (CZ4, ~2,925 HDD) means lower insulation requirements to hit the same Step Code level on the energy model. Designs that need R-28 walls in the Okanagan (CZ5) may only need R-22 in Vancouver, freeing up cost for the heat pump and ventilation upgrades the GHGI limit demands.
- Embodied carbon disclosure: Larger projects under VBBL must report embodied carbon at the design stage, with reduction targets phasing in over the next several code cycles.
- Higher construction volume: Vancouver’s builder network has deep Step Code experience, the energy advisor pool is large, and most major HVAC distributors carry the cold-climate heat pump models that meet VBBL requirements without long lead times.
Metro Vancouver: Municipality Comparison
Metro Vancouver municipalities each set their own Step Code adoption level. The table below summarizes the current minimum for new Part 9 residential construction:
| Municipality | Current Requirement | Notes |
|---|---|---|
| City of Vancouver | Step 3+ (VBBL) | Zero emissions GHGI limit layered on top |
| Surrey | Step 3 | Largest suburban municipality, see Surrey guide |
| Burnaby | Step 3 | Active green building program, see Burnaby guide |
| Richmond | Step 3 | Flood plain considerations affect foundation and slab detailing |
| North Vancouver (District) | Step 4 | Among the most advanced municipalities in the region, see North Vancouver guide |
| West Vancouver | Step 4 | Early adopter of higher steps, common 1.5 ACH50 targets |
Several Metro Vancouver municipalities already require Step 4 or higher, which makes the region a working preview of where the rest of BC is headed under the provincial 2027 Step 4 minimum. If you are an Interior or Island builder watching the timeline, the lessons from current Metro Vancouver projects are directly relevant.
Air Sealing Strategy for Vancouver Builds
Hitting the 2.5 ACH50 target at Step 3 is achievable in Vancouver’s mild climate, but the VBBL’s GHGI overlay raises the stakes on every air leakage point. A leaky envelope forces the heat pump to work harder, drives up the modelled MEUI, and can push a project out of GHGI compliance even when the insulation values look fine on paper.
The most common failure points in Metro Vancouver projects:
- Sill plate to foundation: Coastal moisture makes a continuous gasket non-negotiable; sealant alone tends to fail under the wet-dry cycling
- Rim joist assemblies: Spray foam or carefully detailed rigid foam with sealed edges, every joist bay treated
- Penetrations through the air barrier: Plumbing, electrical, HVAC, and dryer vents each get individual attention rather than a single wrap-up pass at the end
- Window and door rough openings: Backer rod and sealant or sealing tape, not just expanding foam, which compresses and pulls away over time
- Top-of-wall and ceiling plane: Recessed lighting, electrical boxes, attic hatches, and bathroom exhaust penetrations are the most reliable source of late-stage leakage
A pre-drywall blower door test is the single most reliable way to catch leakage before close-in. Builders who test mid-construction consistently hit their final target on the first as-built test. Detailed guidance is available in our air sealing methods comparison.
Permit Process
Standard provincial framework with VBBL additions:
- Pre-construction: Engage a registered energy advisor familiar with VBBL to produce a Section 9.36/Step Code compliance report and a GHGI compliance report
- Permit application: Submit both compliance reports with the building permit application to the City of Vancouver Development, Buildings and Licensing department
- Mid-construction: Optional but strongly recommended pre-drywall blower door test to verify the airtightness target before close-in
- As-built: Final blower door test confirming the airtightness target plus an as-built energy and GHGI compliance report are required before the occupancy permit is issued
For VBBL-specific bulletins and any local amendments, refer to the City of Vancouver building bulletins.
Rebates and Incentives
- BC Hydro New Construction program: Up to $15,000 for high-performance all-electric homes; Vancouver sits inside BC Hydro service territory, so this is the primary rebate stream
- CleanBC Better Homes: Federal and provincial heat pump and high-performance home incentives that stack with utility rebates (details)
- FortisBC: Limited applicability in Vancouver, since most new builds are all-electric, but FortisBC programs remain available where gas service exists for water heating
- City of Vancouver development incentives: Periodic density bonuses and permit fee adjustments tied to higher Step Code or zero-emissions performance — check current bulletins at permit time
For Okanagan and Interior Builders Working in Metro Vancouver
BCStepCode.ca is a province-wide resource. If you primarily build in the Interior and are taking on a Metro Vancouver project, the fundamentals carry over directly: air barrier continuity, pre-drywall verification, and rigorous mechanical system selection. The CZ4 climate gives you margin on the energy side, but the GHGI overlay narrows your mechanical system options significantly compared to a CZ5 Okanagan project.
A few practical adjustments for Interior builders new to Vancouver work:
- Plan for cold-climate heat pumps as the default, not the upgrade
- Budget for embodied carbon documentation if the project triggers VBBL reporting thresholds
- Engage a Vancouver-based energy advisor early; advisors familiar with VBBL will save time during permit review
- Expect more questions from the building department on ventilation and continuous mechanical systems than you would see on a comparable Kelowna or Kamloops project
