What is an Accessory Dwelling Unit (ADU)?

Often referred to as backyard homes, granny flats, in-law units, and guest houses, Accessory Dwelling Units (ADUs) are cost-effective secondary units that can be attached or detached from the primary single-family dwelling. ADUs typically come equipped with a bathroom, bedroom, and kitchen, similar to a stand-alone home.

ADUs can be added to nearly any residential property in the San Diego area as a secondary living area, offering homeowners additional living space at an affordable cost.

While many homeowners choose to use ADUs as a residential unit, these structures can also serve as a guest house, office, storage space, or studio.

Additionally, building an ADU can make a residence more hospitable for both visitors and homeowners. In California, one of the primary reasons people build ADUs is to generate income by renting them out as either a short-term or long-term rental, offering a great potential for additional income.

An ADU can be attached to a primary residence or added to a backyard. In some cases, you can also have a basement or garage conversion, to add living space to your property.

An accessory dwelling unit (ADU) typically serves as a residential building, but a property owner can also use it for other purposes, such as providing guest housing, serving as rental properties, functioning as offices, acting as studios, or serving as storage rooms.

Why It's a Good Idea to Own a San Diego ADU

San Diego is a prime location to build an ADU for various reasons. First and foremost, the shortage of housing options in the area makes ADUs a great solution.

With a limited supply of homes and apartments, ADUs can offer a much-needed boost to the local housing market. Fortunately, the state of California has simplified the process of constructing these additional dwelling units, making it more accessible to homeowners.

Here are a few of the many benefits of accessory dwelling units

ADUs do not require purchasing land

They can raise the value of your home

They are significantly less costly than any other primary residence

They offer extended family members adequate space for comfort and privacy

They offer greater housing options for local residents

ADUs promote multigenerational housing and close family ties

ADUs can lower housing costs

ADUs can provide homeowners with a source of income

ADUs promote adopting sustainable lifestyles

ADUs provide extra room for all of your belongings

Ways to Utilize Your ADU:

As a granny flat to house elderly family members or other relatives

Renting to long-term or short-term residents, students, or professionals

A guest house for visitors

An office or workspace

Additional storage space

A music or photo studio

Temporary living quarters during construction of the primary dwelling

A backyard cottage
