1. Addressing the Housing Shortage

San Diego, like many other cities, is experiencing a shortage of affordable housing options. ADUs offer a practical solution by utilizing existing land and infrastructure to create additional housing units. With the increasing population and limited available space, ADUs help meet the demand for housing while minimizing the need for new construction.

2. Potential Source of Income

ADUs provide homeowners in San Diego with an opportunity to generate additional income. Whether it's renting out the ADU to long-term tenants or utilizing platforms like Airbnb for short-term rentals, homeowners can earn a steady stream of income to offset mortgage payments, cover household expenses, or save for the future.

3. Increasing Property Value

The addition of an ADU can significantly boost the value of a property in San Diego. With the high demand for housing and limited supply, properties with ADUs are highly desirable to potential buyers.

ADUs accommodate changing family dynamics by providing separate living spaces for aging parents, adult children, or extended family members. This allows for increased privacy and independence while maintaining close proximity and familial connections.
