The local suite route in Delta
Delta says secondary suites are permitted in most single-detached houses when zoning and BC Building Code requirements are met. One suite is allowed per single detached dwelling under the city’s current guidance, and a building permit is required before creating or legalizing it.

British Columbia: the provincial layer
The provincial SSMUH framework in B.C. reduces older single-detached zoning barriers and supports suites or ADUs in many circumstances. Verify the municipality’s current bylaw, site standards and permit path for the address.
BC small-scale multi-unit housing ↗Before drawings: four approval questions
What kind of unit?
The approval route can change depending on whether the new home is internal, attached or detached from the main dwelling.
Is the use allowed?
Separate entitlement from construction. The city may allow another unit in principle while still regulating its size, location or form.
Can the building comply?
Construction approval can depend on fire, egress, ventilation, structural and trade-permit details that are invisible on a zoning map.
Can the site serve it?
Site constraints can include parking, sewer and water capacity, electrical service, waste access and setbacks for a detached unit.
For a Delta property, check permission before construction
Move from planning to construction deliberately. A favourable zoning answer still needs code-compliant drawings, permits and completed inspections.
For an existing unit, request the municipal permit history and any final inspection or occupancy record. Present use alone does not prove approval.
