Lake Country Step Code Requirements
Current Step: 3 | ACH Target: 2.5 ACH50 | Climate Zone: 5 | HDD: ~3,750 | Permit Fee Rebate: Step 3, 4, 5 (Bylaw 1070, Section 17.3) | Permit Office: lakecountry.bc.ca | Permit Counter: 10150 Bottom Wood Lake Road
What’s required right now
Step 3 is mandatory for all new Part 9 residential builds in the District of Lake Country under Building Regulation Bylaw 1070. The airtightness target is 2.5 ACH50, verified by blower door test before occupancy.
Lake Country sits in Climate Zone 5 with HDD slightly above Kelowna’s 3,715. The district grew 22% between 2016 and 2021 to roughly 16,000 residents, with most growth in hillside developments at higher elevation than the Wood Lake or Kalamalka Lake shorelines.
Permit fee rebates: the local incentive
Lake Country is one of the few BC municipalities offering a building permit fee rebate tied to Step Code level. Under Bylaw 1070, Section 17.3, projects exceeding the provincial minimum can claim back a portion of permit fees.
| Step Level | Rebate basis |
|---|---|
| Step 3 (provincial minimum) | Standard |
| Step 4 | Permit fee rebate available |
| Step 5 | Higher permit fee rebate |
Since Step 3 is the current floor, the meaningful rebate kicks in at Step 4 or Step 5. For a custom Lake Country build at $1.2M+ where permit fees can run several thousand dollars, the rebate offsets a chunk of the upgrade cost. Confirm current rebate amounts with the Building Department at the time of application.
Four wards, four contexts
Lake Country was incorporated in 1995 from four distinct unincorporated communities. Each still has its own building character and elevation profile.
| Ward | Character | Typical elevation |
|---|---|---|
| Winfield | District centre, commercial spine | 400 to 500 m |
| Okanagan Centre | Lakeshore, established residential | 350 to 450 m |
| Carrs Landing | Premium lakeshore acreages, hillside | 350 to 700 m |
| Oyama | Rural, between Wood and Kalamalka lakes | 380 to 500 m |
Premium hillside developments (Lakestone, The Ponds, Lakepine, Coral Beach) push above 500 m and into noticeably colder winters than the lakeshore. Builders working at upper Lakestone or Carrs Landing should treat the project as upper-CZ5 and budget for R-7.5+ exterior insulation.
Hillside walkout basements: extra surface, extra leakage
Lake Country’s topography pushes most premium construction onto hillside lots with walkout basements. The implications for air sealing and Step Code:
- Walkout walls are exposed foundation, requiring full insulation and air barrier treatment (not just rim joist sealing)
- Stepped foundations multiply the rim joist length and the failure surface area
- Daylight basement window wells become moisture and air leakage paths if not detailed
- Basement-to-main-floor stair openings are a common air barrier discontinuity
A house plan that hits 2.5 ACH50 on a flat Winfield lot can easily fail at 3.5 ACH50 on a stepped Lakestone hillside without specific attention to these transitions.
Permit process at the District
- Pre-construction. Submit energy compliance report with permit application at 10150 Bottom Wood Lake Road. Allow 3 to 5 weeks for permit issuance.
- Mid-construction (optional). District doesn’t currently fund mid-construction blower door tests directly, but they’re worth running. See pre-drywall air sealing.
- As-built. Final blower door test plus updated compliance report. Required before occupancy.
- Permit fee rebate claim. File at occupancy with proof of Step 4 or Step 5 compliance.
For projects in adjacent Regional District of Central Okanagan electoral areas (Joe Rich, Ellison, parts of Westside Road), the RDCO handles building permits, not Lake Country.
Rebate stack for Lake Country projects
| Source | Amount | Notes |
|---|---|---|
| District of Lake Country | Permit fee rebate | Available at Step 4 and Step 5 |
| FortisBC New Home Program | $9,000 to $15,000 | Step 4 with hybrid heat pump |
| FortisBC New Home Program | $11,000 to $20,000 | Step 5 with hybrid heat pump |
| CleanBC Better Homes | $4,000 to $10,000 | Heat pump rebate, stacks with FortisBC |
| Greener Homes Loan | up to $40,000 | Interest-free for energy upgrades |
Combined potential on a Step 4 hillside build: $15,000+ in rebates plus the District permit fee rebate. See the full Step Code rebates guide for stacking rules.
What’s coming in 2027
Step 4 is expected provincially in January 2027 at 1.5 ACH50. Lake Country builders working hillside lots will find Step 4 demanding without aerosol-based air sealing. The combination of stepped foundations, walkout basements, and elevation-driven HDD makes manual sealing alone increasingly hard to land below 2.0 ACH50.
