ADU Builders Group — A Local, Family-Owned ADU Contractor in the Bay Area
ADU Builders Group is a family-owned, locally based company serving the Bay Area with custom accessory dwelling unit construction. With over 21 years of experience in the construction industry and 6 years focused specifically on ADU projects, they have completed more than 100 home improvement projects. Their work centers on helping multigenerational and extended families create practical living solutions on their existing properties.

Their approach reflects a commitment to family-oriented values, balancing closeness with privacy and independence.
Types of ADUs ADU Builders Group Constructs
ADU Builders Group works across several categories of accessory dwelling units, each suited to different property types and family needs:
- Attached ADUs — These are newly constructed or converted dwelling units that physically connect to the primary home. They can be built as additions, above attached garages, as new second stories, or in newly constructed basements. An attached ADU cannot exceed 50% of the existing primary dwelling's floor area. Common uses include multigenerational living arrangements, teenage suites, remote office spaces, and accessible-living configurations for family members with disabilities.
- Detached ADUs — As a detached ADU builder, ADU Builders Group constructs standalone units on lots with existing single-family or multifamily dwellings. These are well-suited as in-law suites, retirement homes, adult children's first homes, or professional consultancy offices. A detached ADU offers full privacy and autonomy while keeping family members nearby.
- Converted ADUs — These units are created from existing space within a primary dwelling or an existing accessory structure. For single-family homes, this may involve converting a garage or other underutilized space. For multifamily properties, non-livable areas such as storage rooms or passageways can be transformed. This type of ADU is a practical option for those looking to maximize existing square footage. ADU Builders Group also operates as a garage conversion contractor in this capacity.
- Junior Accessory Dwelling Units (JADUs) — As a JADU contractor, ADU Builders Group builds compact units of no more than 500 square feet within the walls of an existing single-family home. These provide a private, self-contained space for a family member while remaining part of the main structure.
Beyond standard configurations, they also offer specialized ADU types including retirement ADUs designed for accessible living, home office ADUs optimized for remote work, and modern ADUs with contemporary, eco-conscious design elements.
How the ADU Building Process Works
ADU Builders Group guides clients through each phase of the ADU development process:
- Initial Consultation — Clients begin with a phone consultation followed by an in-person meeting. During this phase, ADU experts provide recommendations and a project estimate at no cost.
- Architectural Design — An in-house architect works with clients to translate their ideas into a formal architectural plan, customized to their specific needs and property.
- Permitting — A dedicated liaison officer manages all permit paperwork and coordinates with the city to keep the process moving efficiently.
- Construction and Inspections — Project managers maintain regular communication with clients throughout construction and ensure all inspections are passed.
- Ongoing Support — After project completion, ADU Builders Group continues to support clients through their warranty program and annual inspections.
One notable aspect of their offering is their warranty structure. ADU Builders Group provides a 3-year project warranty with complimentary annual inspections, in addition to a 10-year structural warranty. They describe this as a distinguishing feature among ADU companies in the region.
ADU Builders Group is also a partner and sister company of Imagine Unique Remodels, extending their capabilities across broader home improvement and remodeling work. Their focus remains on addressing California's housing needs through thoughtful, well-crafted accessory dwelling units that serve real family situations.
