1. What is a dual occupancy home?
Dual occupancy home are two dwellings on a single site and single title. They are attached with a common wall or completely detached and sometimes share features such as front yard and car parking access. Dual occupancy homes are built on one piece of land and cannot be subdivided.
The perfect location for dual occupancy homes are in suburban neighbourhoods. Residents enjoy similar living arrangements with lower maintenance and housing costs, a perfect living arrangement for multi-generational living.
