Accessory Dwelling Unit Benefits

Often called 'granny flats', Accessory Dwelling Units (ADUs) are smaller, self-contained living spaces located on the same property as a single-family home. These units can provide affordable housing options for family members, friends, students, the elderly, in-home health care providers, the disabled, and others.

ADUs can be attached to the main house, like an above-the-garage unit or a basement apartment, or they can be independent structures such as a cottage or carriage house.

Adding an ADU to your property offers several benefits. Whether it's an apartment over the garage, a tiny home in the backyard, or a basement apartment, an ADU can provide additional space for a growing family or generate rental income.

Guest Quarters

Provide a clean, comfortable, private space for visiting guests be they friends or family

Passive Income

Generate passive income by renting out the additional living space to a tenant

Increased Property Value

Gain immediate equity in your home, as you can typically build an accessory unit for a lower cost per square foot than what is typical for San Diego property values
