Types of ADUs You Can Build in Hawthorne
Choosing the right type of ADU depends on your property, available space, and how you plan to use the new living area. We build detached ADUs, attached ADUs, garage conversion ADUs, and JADUs throughout Hawthorne.
Detached ADUs
A detached ADU is a completely separate structure from your primary home, typically built in the backyard or another available area of the property. Detached ADU construction can create an independent living space with its own kitchen, bathroom, bedroom, living area, and private entrance.
Attached ADUs
An attached ADU connects to the existing home while providing additional independent living space. Depending on the property, this can involve expanding the existing structure to create the new unit.
Junior ADUs (JADUs)
A JADU is a smaller accessory dwelling unit created within the existing or proposed space of a single-family home. It can be a practical option when you want additional living space without constructing a full-size detached structure.
Garage Conversion ADUs
A garage conversion transforms an existing garage into a permitted living space. Depending on the existing structure, the project can include insulation, new walls and flooring, windows and doors, electrical, plumbing, HVAC, a kitchen, bathroom, and interior finishes.
How Much Does an ADU Cost in Hawthorne?
The cost of ADU construction in Hawthorne depends on the type and size of the ADU, site conditions, utility connections, structural requirements, materials, and finishes.
JADU (Junior Accessory Dwelling Unit): $60,000–$110,000
Garage Conversion ADU: $90,000–$180,000
Attached ADU: $160,000–$320,000

Garage conversions may cost less than new ADU construction because they use an existing structure, while attached and detached ADUs typically require more extensive foundation, framing, utility, and construction work.
