Penticton Step Code Requirements

Current Step: 3 | ACH Target: 2.5 ACH50 | Climate Zone: 5 | Permit Office: penticton.ca/building

Current Requirements

Step 3 required for all new Part 9 residential buildings. Penticton sits at the warmer end of Climate Zone 5, making Step 3 compliance relatively straightforward.

Climate Advantage

Warmest climate in the Okanagan. Lower heating degree days mean the energy model is less demanding. Standard insulation and good-quality double-pane low-E windows typically suffice.

Permit Process

Pre-construction energy model, blower door test at 2.5 ACH50, and as-built compliance report. Standard BC framework.

Focus Areas

The blower door test is pass or fail regardless of climate zone:

• Air barrier continuity from foundation to roof
• Flashing and sealants at window/door rough openings
• Rim joist and foundation transitions
