The popularity of ADUs is skyrocketing across San Diego. The City of San Diego reports that in 2023, more ADUs were built than single-family homes. They are providing new housing opportunities and lower-cost living around the city. In fact, the San Diego Housing Federation found that the county is short over 134,000 homes for low-income renters, and with ADUs generally offering slightly cheaper rent than traditional housing, they might just be the solution to a housing shortage.
This guide aims to help homeowners and renters understand the process of building an ADU in San Diego and the potential benefits.
Understanding What an ADU Is
San Diego County defines an ADU as an attached or detached residential dwelling unit that is 1,200 square feet or less, provides complete independent living amenities and is located on a lot with a preexisting single-family dwelling.
There are six common types of ADUs:
- Detached
- Attached
- Upper-Level Interior
- Lower Level Interior
- Above Garage
- Garage Conversion
Benefits of Building an ADU
- Increased Property Value: Adding an ADU can increase your home value because it provides additional living space with increased square footage and the opportunity for the homeowner to generate rental income.
- Additional Rental Income: Renting out your ADU can make you anywhere from $800 to $3,000 extra income. In San Diego, the rental market is huge, and the demand is high. You can use the rental income from an ADU to assist with mortgage payments and other property expenses.
- Flexible Living Arrangements: Aside from renting out ADUs, many build to have more space for their family. Multigenerational families can use them to house different parts of the family, allowing them to be close together while having a private space.
- Affordable Housing Solution: With the high cost of living in San Diego, low income and affordable housing is in high demand. ADUs are much more affordable than home rentals.
- Environmental Benefits: ADUs help prevent urban sprawl by providing more residencies in city areas. Urban sprawl often converts rural natural areas into development sites to accommodate for a growing population.
Designing Your ADU
When considering an ADU build, you should first consider the purpose of your added space. Does your child’s family want to move back in, and do your in-laws need a bit of support? Are you housing your daughter and her college friends? Do you want a live-in nanny but with a bit of privacy? Or are you looking to generate some extra rental income? Your need directly affects the design of your space. While thinking about floor plans and design styles, also keep in mind what kind of functionality decisions best fit your needs. For example, if you plan on housing an older couple, you may choose accessible entrances and spaces. If you are housing college students, you may not want the most expensive hardwood floors on the market.
Some popular San Diego ADU designs include
- Contemporary
- Two-story
- Spanish-style
When thinking about building, think about the space your ADU will be occupying. Naturally, the ADU will take away some of your property space, so think about how much you are willing to give. With this in mind, you may choose a two-story ADU to maximize backyard space.
