PRODUCT DESCRIPTION

The BOSS One Bed Plus is a 500 sq ft one-bedroom prefab ADU (accessory dwelling unit) built in California by BOSS Homes — a modern, code-ready backyard home ideal as a rental unit, guest house, home office, or independent living space for family. Its 16’ × 32’ footprint and 11’6” overall height create a spacious one-bedroom layout, while precision-engineered light-gauge steel framing delivers exceptional structural strength and low-maintenance durability. The One Bed Plus ships on standard pallets — no cranes or oversized transport — and most projects move from order to move-in in roughly 4 to 9 months.

Like every BOSS model, the One Bed Plus is engineered to meet both the International Building Code (IBC) and California Building Code (CBC), so it is permittable as a backyard ADU or granny flat across California — including Los Angeles, San Diego, San José, and more. Explore the full prefab ADU guide or browse all 8 BOSS models.
