What Is an Accessory Dwelling Unit (ADU)?
An accessory dwelling unit (ADU) is a secondary housing unit located on the same lot as a primary residence. We see ADUs as a practical solution to maximize living space without the need for additional land, particularly valuable in Harbor City where property densities average about 9,127 people per square mile.
ADUs can take several forms, such as detached units, attached units, or conversions of existing spaces like garages or basements. Each type offers flexibility depending on the property's layout and the homeowner's goals, with designs that can be adapted to Harbor City's mild climate, which boasts approximately 284 sunny days per year and only about 14 inches of annual rainfall, mostly concentrated
in December through February.
Key features of an ADU include:
- Independent entrance
- Kitchen and bathroom facilities
- Sleeping area
- Climate-appropriate insulation (important for Harbor City's summer months when temperatures can reach the mid-80s°F)
These features make ADUs fully functional, self-contained dwellings. They can serve various purposes, including rental income, housing family members, or providing extra space for guests in this neighborhood where 18.1% of residents aged 25 or older have completed a four-year degree.
