Prefab ADU in Watsonville

What is an Accessory Dwelling Unit (ADU)?

An ADU is an independent residential unit on the same lot as a primary home, providing additional living space, rental opportunities, or multi-generational housing. A prefab ADU is a permanent, factory-built backyard home that meets local zoning and building codes, making it ideal for long-term living.

Tiny homes, often confused with prefab ADUs, are small, mobile units built on wheels. While both can be considered ADUs, prefab ADUs are stationary and built to last, whereas tiny homes face more zoning challenges due to their mobility.
