Accessory Dwelling Units (ADUs) and Junior Accessory Dwelling Units (JADUs) stand out as innovative and highly effective solutions for addressing the pressing need for additional housing in California.

Accessory Dwelling Units (ADUs) have gone by various names, including granny flats, in-law units, backyard cottages, secondary units, and more. The California Department of Housing and Community Development (HCD) has taken a leading role in shaping local ADU ordinances. Although these ordinances are optional, their popularity has surged as more cities, counties, and homeowners recognize ADUs as a valuable means of expanding the availability of affordable housing.

The benefits of Accessory Dwelling Units (ADUs) in California are numerous:

1. Affordability: ADUs are a cost-effective housing option because they don't require the purchase of new land, major infrastructure investments, structured parking, or elevators, making them a more budget-friendly choice.
2. Income Source: Homeowners can generate additional income by renting out ADUs, providing a supplementary revenue stream that can help offset housing costs.
3. Cost-Effective Construction: ADUs are constructed using cost-effective wood frame construction methods, which are notably less expensive than building new multifamily infill structures.
4. Proximity with Privacy: ADUs enable extended families to live in close proximity to one another while still maintaining privacy. This arrangement is particularly useful for families who want to stay connected while retaining personal space.
5. Living Space: ADUs can offer living spaces comparable in size to many newly-built apartments and condominiums. They are well-suited for couples, small families, friends, young adults, and seniors, catering to a broad range of housing needs.
6. Flexibility: ADUs provide homeowners with the flexibility to share independent living areas with family members and others. This flexibility is especially valuable for seniors who may require additional care and wish to age in place while maintaining their independence.

ADUs contribute to the diversification and expansion of housing options in California, offering a range of advantages for homeowners and communities alike.
