PRODUCT DESCRIPTION

The BOSS Two Bed Basic is a 780 sq ft two-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, multigenerational living space, or independent home for family. Its 26’ × 30’ footprint and 11’6” overall height create a comfortable two-bedroom layout, while precision-engineered light-gauge steel framing delivers exceptional structural strength and low-maintenance durability. The Two Bed Basic 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 Two Bed Basic 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.
