Installing a fully certified and high-quality granny flat can increase property value and market appeal. Value impact depends on:

Zoning rules that allow the granny flat to be rented independently

Quality of construction, finishes, and approvals

Local demand for rental properties or multigenerational living

Expandify homes are engineered, certified, and delivered with full occupancy approval — often making them more appealing than traditional site-built structures. For investors, they can provide a positive rental yield and increased equity.
