Types of ADUs You Can Build in Carson
Detached ADUs
Our detached ADU construction in Carson creates fully independent living spaces separate from the main home. Detached ADUs can include a kitchen, bathroom, bedroom, living area, and private entrance, making them a popular option for rental income, multigenerational living, guests, or a private home office.
Attached ADUs
Attached ADUs expand your existing home with a self-contained living space connected to the primary residence. They provide separate living quarters while remaining integrated with the existing home.
Junior ADUs (JADUs)
JADUs convert qualifying existing space within the home into a compact independent living unit. They can be a practical option for creating additional living space without constructing a separate structure.
Garage Conversion ADUs
Garage conversions transform an existing garage into a functional accessory dwelling unit with options for a kitchen, bathroom, bedroom, living area, and private entrance.

How Much Does an ADU Construction Cost in Carson?
The cost to build an ADU in Carson depends on the type and size of the unit, site conditions, utility connections, structural requirements, materials, and finishes.
JADU (Junior Accessory Dwelling Unit): $60,000–$120,000
Garage Conversion ADU: $100,000–$200,000
Attached ADU: $175,000–$325,000
Detached ADU: $225,000–$450,000+
Garage conversions can often cost less because they use an existing structure, while a new detached ADU typically requires a foundation, framing, roofing, utility connections, and complete interior construction.
These ranges are general planning estimates. During your consultation, we’ll evaluate your property, ADU type, and project scope to provide a more detailed estimate.
