The local suite route in Nanaimo
Nanaimo says one secondary suite is allowed per dwelling and that a utility charge does not by itself prove a suite is legal. A suite is authorized through the building-permit process; carriage houses are handled under a separate permit route.

British Columbia: the provincial layer
British Columbia’s SSMUH rules broaden the housing that local governments must allow in many residential zones. Secondary suites and detached ADUs are part of that framework, but municipal siting, permitting and applicable exemptions still matter.

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?
Do not assume a provincial housing reform means every design is automatically allowed on every lot. Verify the local implementation and exemptions.
Can the building comply?
Life-safety and building-system requirements can be the hardest part of legalizing an older unit, so investigate them before cosmetic work.
Can the site serve it?
The parcel has to support the unit physically as well as legally, including servicing, access and any required setbacks.
Build the Nanaimo approval file in order
Treat permission for another dwelling and approval of the construction as separate questions. Zoning answers one; building and trade permits answer the other.
Treat suite status as a due-diligence item. Request records rather than assuming long-term use equals compliance.
