Accessory Dwelling Unit (ADU) - Flexible Living Solutions for Modern Homes
Accessory Dwelling Units (ADUs) and Junior Accessory Dwelling Units (JADUs) serve as an innovative and effective means of expanding housing options.
An Accessory Dwelling Unit (ADU) is a self-contained residential unit, either attached or detached, that offers complete living facilities for one or more people. It’s situated on the same property as an existing or planned primary residence and includes permanent provisions for living, sleeping, eating, cooking, and sanitation.
Modular ADU
What is JADU?
In California, a Junior Accessory Dwelling Unit (JADU) is an innovative housing option created within the existing walls of a single-family home, limited to a maximum of 500 square feet.
JADUs are designed to minimize development costs by potentially sharing central systems and bathrooms with the primary dwelling, and they utilize a basic kitchen setup with small plug-in appliances. Because JADUs repurpose existing space and don’t expand a home’s planned occupancy, they place no additional strain on utility services or infrastructure.

What are the benefits of ADUs and JADUs?
Accessory Dwelling Units (ADUs) offer a multitude of advantages for homeowners and communities, especially in California. Here are some key benefits:
Affordable to Build
ADUs are a cost-effective housing solution because they don’t require the purchase of new land, extensive new infrastructure, structured parking, or elevators. This significantly reduces overall construction expenses.
Income Generation
Homeowners can generate a valuable source of income by renting out their ADU, helping to offset mortgage costs or supplement their finances.
Increased Property Value
Adding an ADU can significantly enhance your home’s value. As demand for housing continues to grow, homes with ADUs are often seen as more desirable and versatile.
Cost-Effective Construction
Built with efficient wood-frame construction, ADUs are considerably less expensive to build than units in new multifamily buildings.
Proximity with Privacy
ADUs allow extended families to live close to one another while still maintaining their individual privacy and independence.
Spacious Living
An ADU can offer as much living space as many newly constructed apartments and condominiums, making them an ideal option for couples, small families, friends, young professionals, and seniors.
Flexible Living Arrangements
ADUs provide homeowners with the flexibility to share independent living areas with family members or others. This is particularly beneficial for seniors who wish to age in place while having easy access to care or companionship.
