What Langley publishes for additional units
Langley City publishes a dedicated secondary-suite building-permit application, guide and declaration through its building-permit page. Use those local forms rather than assuming a suite is approved simply because a dwelling already exists.

British Columbia: the provincial layer
British Columbia sets a province-wide small-scale multi-unit housing framework that includes secondary suites and detached accessory units. Local governments still administer zoning details, building permits and property-specific exceptions.
BC small-scale multi-unit housing ↗The four suite checks to do first
What kind of unit?
Internal basement suites, upper-level suites and detached garden or laneway units can follow different zoning and building paths.
Is the use allowed?
Establish that the unit form is allowed on this parcel before solving construction details or applying for trade permits.
Can the building comply?
Expect construction details such as egress, smoke/CO protection, ventilation and fire separation to influence the final layout.
Can the site serve it?
Parking may be only one site issue; utilities, garbage access, lot coverage and detached-unit siting can matter too.
Build the Langley approval file in order
The project is not finished at permit issuance. Track inspections and final sign-off so the approval record matches the completed dwelling.
A tenant in place does not establish legality. Verify the municipal record and any outstanding permits or orders.
