Key points from the guide
- Most Metro Vancouver lots can hold 3 or 4 homes under BC's small-scale housing rules, and 6 near frequent bus service, so a family can give each household its own home.
- A secondary suite stays on the main house's title; the homes of a duplex or multiplex can become separate strata lots if this is set up before anyone moves in.
- The BC Building Code asks for STC 50 or ASTC 47 between duplex or multiplex homes, against STC 43 or ASTC 40 between a house and its suite.
- Most family homes are exempt from the code's accessibility rules, so wider doors, step-free entries and main-floor bedrooms for older parents are the family's choice.
- The federal Multigenerational Home Renovation Tax Credit is 14.5% of up to $50,000 for the 2025 tax year (CRA, January 2026), one claim per senior or disabled adult in their lifetime.
- Family co-owners should decide between joint tenancy and tenancy in common, sign a co-ownership agreement and update their wills before construction starts.
