Why Multiplex for Multigenerational Living?
Traditional multigenerational arrangements force families into compromises: a basement suite with limited light, a laneway house that only fits one generation, or overcrowded shared spaces. A multiplex eliminates those trade-offs.
Privacy + Proximity
Each generation gets a self-contained unit with its own entrance, kitchen, bathroom, and living space. But you share the same address, the same yard, and the same property title. Grandparents are next door, not across town. Adult children have independence without paying $2,800/month rent.
Financial Advantage
A single-family home worth $1.8M can become a multiplex valued at $5.0-5.6M. That equity funds construction, replaces the need for rental housing, and creates intergenerational wealth. Blended family income strengthens mortgage qualification. One property serves the financial needs of an entire family.
Aging in Place
Purpose-designed accessible units allow seniors to age safely at home with family nearby. Main-floor bedrooms, walk-in showers, wide doorways, and zero-step entries mean no move to assisted living. Families save $4,000-8,000/month compared to care facility costs while maintaining dignity and connection.
Next-Generation Affordability
With the median Vancouver home at $2.0M+, adult children face a 15-20 year savings timeline for a down payment. A multigenerational multiplex provides immediate homeownership within the family property, building equity from day one instead of paying rent that builds someone else's wealth.

How It Works: From Feasibility to Move-In
Feasibility Assessment
We analyze your lot dimensions, zoning, servicing capacity, and family needs to determine unit count, layout options, and financial viability. This includes a preliminary pro forma showing construction costs, timeline, and projected value creation.
Family Planning Workshop
We work with your family to define each generation's space requirements, accessibility needs, shared vs. private areas, and budget parameters. This ensures the design brief reflects how your family actually lives.
Design & Permitting
Our architect team produces drawings that meet municipal requirements while optimizing for multigenerational living: separate entrances, accessible units, sound insulation, and shared outdoor space. We manage the full permitting submission.
Financing & Pre-Construction
We arrange construction financing using blended family income where applicable, coordinate CMHC programs, and prepare for the MHRTC tax credit. Pre-construction includes trades scheduling, materials procurement, and site preparation.
Construction & Move-In
VanPlex manages construction delivery with SSMUH-experienced trades. We coordinate phased occupancy if needed, so one generation can move in while finishing touches complete on other units. Final inspections, occupancy permits, and keys.
Tax Benefits for Multigenerational Builds
The federal Multigenerational Home Renovation Tax Credit (MHRTC) provides a 15% refundable credit on up to $50,000 of eligible renovation expenses, yielding up to $7,500. The credit applies when creating a secondary dwelling unit for a qualifying relative who is 65+ or has a disability.
Beyond the MHRTC, multigenerational multiplex owners benefit from principal residence exemption on their occupied unit, potential capital gains deferral strategies, and income splitting through family-member tenancies.

- Eligible expenses: Up to $50,000
- Credit rate: 15% refundable
- Max credit: $7,500 per qualifying renovation
- Qualifying relative: Senior 65+ or adult with disability
- Requirements: Must create a self-contained secondary unit with private entrance, kitchen, and bathroom
- Claim period: Year renovation is completed
Design Principles for Multigenerational Multiplex
A well-designed multigenerational multiplex balances independence with connection. These principles guide every VanPlex family build.
Accessible Units
At least one unit designed for aging in place: main-floor bedroom and bathroom, 36"+ doorways, zero-step entry, reinforced walls for grab bars, lever handles throughout, and roll-in shower capability.
Separate Entrances
Each unit requires its own dedicated entrance. Best practice positions entrances on different sides of the building or uses a shared lobby with private vestibules to maintain independence and reduce noise transfer.
Shared Outdoor Space
A central courtyard, shared garden, or connected deck area creates natural gathering points for family meals, celebrations, and daily interaction without encroaching on private unit space.
Sound Insulation
STC 55+ ratings between units, resilient channel mounting, acoustic insulation in party walls, and strategic unit placement (bedrooms away from shared walls) ensure privacy and comfortable living.
Flexible Floor Plans
Units designed with demountable walls or convertible rooms allow families to adapt spaces as needs change: a nursery today becomes a home office in five years, then a caregiver suite in fifteen.
Cultural Sensitivity
Many multigenerational families have specific cultural needs: larger gathering kitchens, dedicated prayer or meditation rooms, shoe-removal entries, or multi-purpose family rooms. These are integrated from day one.
