Why ADUs Are a Smart Investment in San Diego
San Diego's real estate market is among the most competitive in the country. Adding an ADU to a property can increase its market value by an estimated 20% to 30%, making it a sound long-term investment. Prospective buyers often view the additional living space as a flexible and attractive feature worth a premium price.
With San Diego's high cost of living, many homeowners also look to ADUs as a way to generate consistent rental income. Given the strong demand for rental properties in the area, ADUs can typically be rented out quickly and at competitive rates, helping offset mortgage payments and other household expenses.
Beyond financial benefits, ADUs offer a practical solution for families looking to house aging parents, adult children, or other relatives. They provide a private, comfortable living space while keeping loved ones nearby — often a more cost-effective arrangement than alternative housing options.
