Vancouver R1-1 Step Code 5 Blueprint: Unlocking 1.25 FAR & Zero Parking Multiplexes

How Metro Vancouver multiplex builders and developers unlock 1.25 Floor Area Ratio (FAR), eliminate underground parking minimums under amended By-law 6059, and achieve Step Code 5 Net-Zero performance to add over 1,200 sq ft of buildable floor area and $1.2M+ in pro-forma project equity on standard residential lots.

1. The Vancouver R1-1 District Schedule & 1.25 FAR Density Lift

The City of Vancouver’s comprehensive multiplex framework under the R1-1 (Residential Inclusive) District Schedule represents the most aggressive density transformation in modern British Columbia land development history. Replacing legacy single-detached zones (RS-1, RS-3, RS-5), R1-1 permits 3 to 4 units on standard 33-foot lots and up to 6 strata or 8 secured rental units on 50-foot lots.

However, the true financial engine of the R1-1 schedule is its performance-tiered density bonus. While a baseline multiplex is restricted to 0.70 Floor Area Ratio (FAR), developers who design to BC Energy Step Code 5 (Net-Zero Energy Ready) unlock the maximum allowable 1.25 FAR. On a standard 50′ x 120′ lot (6,000 sq ft lot area), this density multiplier expands gross buildable area from 4,200 sq ft to 7,500 sq ft—creating over 1,200 to 2,000 sq ft of additional livable density.

2. Zero Parking Minimums: Eliminating the $100K Parkade Trap

Under the amended Vancouver Parking By-law No. 6059, vehicular parking minimums have been completely eliminated for R1-1 multiplex infill developments. Historically, mandatory off-street parking forced builders to excavate underground concrete parkades or dedicate ground-floor building footprints to vehicular garages—sacrificing high-value residential square footage.

Eliminating on-site parking delivers three immediate pro-forma advantages:

• Capital Cost Savings ($80,000 – $150,000): Eliminates shoring, deep bulk excavation, concrete slab engineering, and waterproofing associated with below-grade vehicular parking.
• Recaptured Ground-Floor Living Area: Converts 400 to 700 sq ft of driveway ramps and garages into garden suites or dedicated courtyard amenities.
• Sustainable Urban Mobility: Projects replace concrete stalls with Class A secure indoor bicycle storage and EV charging conduits, qualifying for CMHC climate credits.

3. High-Performance Step Code 5 Building Envelope Engineering

To secure the full 1.25 FAR bonus, the municipal energy compliance model requires rigorous building science detailing overseen by a certified Energy Advisor and BC Licensed Residential Builder:

• Continuous Exterior Insulation (R30+ Effective): 2-to-3 inches of rigid mineral wool (Rockwool Comfortboard) continuous exterior insulation eliminating all framing thermal bridges.
• Airtightness Barrier (Under 1.0 ACH50): Precision-sealed self-adhered vapor-permeable weather resistive barriers (Siga Majvest / ProClima) verified via mandatory pre-drywall blower door testing.
• Triple-Glazed Low-E Argon Glazing: High-performance European-style tilt-and-turn vinyl or fiberglass frames with overall U-values below 1.05 W/m²K.
• Centralized Heat Recovery Ventilation (HRV): Dedicated high-efficiency HRV units (Zehnder / Venmar) achieving 80%+ sensible heat recovery efficiency.
• Cold-Climate Variable-Speed Heat Pumps: Fully electrified heating and cooling systems operating at sub-zero temperatures without electric resistance backup.

4. CMHC MLI Select 50-Year Amortization & Financing Pro-Forma

By combining Step Code 5 energy modeling with purpose-built rental multiplex design (4 to 8 units), developers achieve the maximum 100-point threshold under the CMHC MLI Select Program.

This unlocks 50-year amortization schedules, up to 95% Loan-to-Cost (LTC) financing, and significant interest rate premium discounts—dramatically lowering debt service costs and maximizing long-term cash flow yields.
