Portable & Prefab: Quick assembly and relocation.
Customizable: Layout, materials, and finishes.
Eco-Friendly: Solar panels, rainwater collection, and composting toilets.
Multi-Purpose: Can be used as an office, guest room, or tiny home.
3. Where to Buy?
Companies like Boxabl, Kithaus, and Inhabitat offer modular homes.
Alibaba & Amazon have cheap prefab ADUs.
Local manufacturers may offer custom designs.
4. Important Considerations
Utilities: Even if the unit is permit-free, adding plumbing and electricity might require approvals.
