Build two homes on one block
Dual occupancy development lets you build two dwellings on a single block, either side-by-side or front-and-back. It's popular for maximising land value, creating rental income, or keeping family close. Adelaide's changing zoning rules have opened more opportunities for dual occupancy.
Dual occupancy means two separate dwellings on one title, sharing the land but each with independent access. Unlike a granny flat, both dwellings are typically similar in size and can be separately titled (Torrens or Community) for individual sale. Common configurations include side-by-side duplexes, front-and-rear layouts, or double-storey designs.
Costs include both dwellings. Land subdivision (if creating separate titles) adds $20,000-$40,000. Compare to land value and potential resale/rental returns.
