As Vancouver homeowners look for ways to add rental income and living space, two terms often come up: ADUs (Accessory Dwelling Units) and Laneway Homes. While the two are similar, there are key differences in design, placement, and regulations that homeowners should understand before starting a project.
This guide explains the difference between ADUs and laneway homes, and which option makes sense in Vancouver’s housing market.
🏡 What Is an ADU?
An Accessory Dwelling Unit (ADU) is a secondary housing unit on the same lot as a primary residence. ADUs come in different forms, including:
- Basement suites (within the main house)
- Garden suites (built in the backyard, not on a lane)
- Laneway homes (built facing the rear lane)
- Garage conversions (repurposing existing garages)
In short, laneway homes are a type of ADU — but not all ADUs are laneway homes.
🚪 What Is a Laneway Home?
A laneway home is a specific type of ADU built in the backyard of a property that has lane access.
- Detached from the main house
- Faces the lane rather than the street
- Must follow Vancouver’s zoning, setback, and parking rules
