Yes — Expandify homes are fully self-contained Class 1a dwellings and may be rented out to non-family members, provided:

Local council permits rental use for secondary dwellings

You obtain occupancy approval through CDC or DA

Appropriate landlord or short-stay insurance is in place

As of 2023, most councils across NSW, VIC, QLD, and WA allow rental use, but individual approval may still depend on site zoning.
