Laneway Home & Legal Suite
A laneway home or legal suite adds a second address to a lot you already own.
Two ways to add a home on the same lot
A laneway home is a small, standalone house built at the back of a lot, usually facing a lane. A legal suite is a self-contained unit inside the main house, such as a basement suite, registered with the city as its own dwelling. Costar's Kitsilano project on West 10th Avenue included both a legal suite and a laneway home on the same lot, each carried through permit application and new-build construction.
Permits are part of the build, not a separate step
Both project types need permit approval before construction starts, since a laneway home or a legal suite has to meet its own set of zoning and building code rules. Costar's process folds permit application into the same project timeline as design and construction, available in Vancouver, Burnaby and New Westminster.
Questions
Frequently asked questions about Laneway Home & Legal Suite
What is the difference between a laneway home and a legal suite?
A laneway home is a small, standalone house built at the back of a lot, typically facing a lane. A legal suite is a self-contained unit built inside the main house, such as a basement suite, and registered with the city as its own separate dwelling.
Can I build both a laneway home and a legal suite on the same lot?
Costar's Kitsilano project on West 10th Avenue in Vancouver included both a custom legal suite and a laneway home on the same lot, each taken through permit application and new-build construction, so both are possible on one property where zoning allows it.
Where does Costar build laneway homes and legal suites?
Costar builds laneway homes and legal suites in Vancouver, Burnaby and New Westminster.
Does a laneway home or legal suite need a building permit?
Yes. Both project types need permit approval before construction starts. Costar's process includes permit application as part of the project timeline, alongside design and construction, rather than as a separate step the client manages alone.
Can a legal suite be added inside an existing house?
Yes. A legal suite is a self-contained unit built inside the main house, such as a basement suite, and registered with the city as its own dwelling. Costar's Kitsilano project on West 10th Avenue added a custom legal suite this way as part of a project that also included a laneway home.
Does a laneway home face the street or the back lane?
A laneway home is a small, standalone house built at the back of a lot, typically facing the lane rather than the street the main house faces.
Why do laneway homes and legal suites need their own zoning review?
Each project type has to meet its own set of zoning and building code rules that are separate from the rules for the main house on the lot, which is why permit approval is required before construction starts on either a laneway home or a legal suite.
Does Costar manage the permit process for a laneway home or legal suite?
Yes. Costar folds permit application into the same project timeline as design and construction for laneway homes and legal suites in Vancouver, Burnaby and New Westminster, rather than leaving permitting as a separate task for the client.
