Accessory Dwelling Unit Design & Construction by Summit Building Group
Summit Building Group offers full-service Accessory Dwelling Unit (ADU) solutions, covering every stage of the process — from initial concept and design through permitting and final construction. Based in Sacramento, CA, they work with homeowners looking to build an ADU for a range of purposes, including rental income, multigenerational living, home office space, or guest accommodations. They also collaborate with select prefab ADU build companies to expand the options available to their clients.
An ADU can serve multiple practical functions. It can generate rental income as a fully functional second unit, add long-term value to a property, provide a private living space for family members, or create a dedicated workspace separate from the main home. Summit Building Group positions itself to support homeowners through all of these scenarios.
