Accessory Dwelling Units—commonly known as ADUs—are reshaping the way homeowners in San Diego think about space, flexibility, and long-term investment. Whether it’s a detached backyard cottage, a converted garage studio, or an above-garage apartment, ADUs offer a smart way to expand living space, generate rental income, or accommodate multigenerational living.
In a city celebrated for its architectural diversity and coastal charm, ADU homes have become a defining feature of neighborhoods seeking both character and practicality. From historic bungalow districts to mid-century family communities, San Diego offers a variety of areas where ADU properties flourish.
What is an ADU?
An ADU, or Accessory Dwelling Unit, is a self-contained residential space built on the same lot as a primary home. These units typically include a kitchen, bathroom, and private entrance—essentially a smaller home designed for independent living.
Homeowners in San Diego are embracing ADUs for their versatility and financial benefits. Whether used as a rental unit, guest suite, or home office, ADUs can significantly boost property value while providing housing flexibility in a competitive market.
