Accessory dwelling units for rental income, family, or flexibility, designed, permitted, and built by your local contractor.
Accessory dwelling units (ADUs) are one of the smartest investments an East Bay homeowner can make. Whether it is rental income, a place for aging parents, a home office, or a guest house, an ADU adds living space and long-term value to your property. J&B Homes designs, permits, and builds detached ADUs, garage conversions, and attached units across the East Bay.

From a compact backyard cottage to a full two-bedroom unit, we build ADUs that pay you back for decades.
