ExpandADU | Prefab ADUs

Families and homeowners across Fremont and the East Bay turn to ExpandADU | Prefab ADUs for end-to-end accessory dwelling unit construction that moves from feasibility study and city permits through prefab design, site preparation and final installation. We manage the whole project under one roof, so you get clear communication, transparent pricing with no surprises, and a single team that keeps you informed from the first call to move-in.

Our team also helps with the practical details, including coordinating utility timelines and advising on floor plans that can help keep permit and project costs in check. Many of our clients are looking for a rental unit or a home for family, and we're proud to help them through the process with steady guidance and attention to detail.

Each prefab ADU is built to a high standard and comes with a complete interior, from kitchen cabinets and countertops to finishing touches, ready for you to move in.
