ADU Construction

The client builds from the ground up, an Accessory Dwelling Unit (ADU) – Which is a small secondary housing unit located on the property as a main home, also referred to as an In-law suit. An ADU is an independent living space with its own entrance, kitchen, bathroom, and sleeping area.

Green Living Builders, LLC brings generations of building expertise to every ADU construction project. As a third-generation Bay Area contractor, we're dedicated to creating purposeful spaces that improve how people live. Our team has built ADUs across the East Bay, including garage conversions, detached units, attic apartments, and more. Backed by our service as the West Region Director for Habitat for Humanity International and leadership of Global Village builds across five continents, we combine deep construction experience with a commitment to community and thoughtful design.

Benefits of Building an ADU

An accessory dwelling unit (ADU) offers practical and flexible living space on your property.

Common uses and benefits include:

  • Housing aging parents
  • Providing space for returning adult children
  • Creating a private guest house
  • Offering a quiet area for an office, studio, or home-based business
  • Earning passive income through short- or long-term rentals
  • Planning for future retirement income with rental flexibility
  • Downsizing into an ADA-friendly unit
  • Increasing property resale value

Each ADU can be designed to meet one or more of these needs, giving you freedom to adapt the space over time as circumstances change.

How Do You Plan an ADU Floor Layout?

A good ADU floor layout prioritizes open living space, natural light, and privacy. Most include a combined kitchen and living area, one or two bedrooms, a full bath, and storage. Windows are placed to maximize daylight and airflow, while entrances are positioned for easy access and separation from the main home. Some layouts include flexible areas that double as workspaces or guest accommodations.

What Is Green and Sustainable Construction in ADU Projects?

Green and sustainable construction in ADU projects involves using materials and building methods that reduce environmental impact while supporting long-term efficiency and health.

This includes selecting eco-friendly products, such as low-VOC finishes, energy-efficient windows, and insulation that improves temperature control. Sustainable building also emphasizes resource-conscious planning, including reducing construction waste and sourcing local materials whenever possible. These choices benefit the environment and can also help you lower utility costs.
