Why Carriage Houses Work for Island Living

Carriage homes (detached accessory dwelling units) offer flexible living spaces ideal for rental income, guest suites, or work-from-home studios. In Nanaimo, Parksville, and Courtenay, these home additions are rising in popularity, adding equity while preserving yard space and supporting multigenerational living.
