Types of ADUs You Can Build in Manhattan Beach
Choosing the right type of ADU depends on your property, available space, and how you plan to use the new living area. Our Manhattan Beach ADU contractors build detached ADUs, attached ADUs, garage conversion ADUs, and JADUs for rental income, multigenerational living, guests, home offices, and other needs.
Detached ADUs
Our detached ADU construction in Manhattan Beach creates fully independent living spaces separate from the main home. Many homeowners choose detached ADUs for rental income, multigenerational living, guest accommodations, or a private home office.
Attached ADUs
Attached ADU construction expands your Manhattan Beach home with an independent living space connected to the primary residence. This can be a good option for adding usable square footage without building a completely separate structure.
Garage Conversion ADUs
Our garage conversion contractors in Manhattan Beach transform existing garages into functional living spaces with options for a kitchen, bathroom, bedroom, and living area. A Manhattan Beach garage conversion can create an ADU for family, guests, rental use, or additional living space while utilizing your home's existing footprint.
Junior ADUs (JADUs)
JADUs convert existing space within the primary residence into a smaller independent living unit. They can be a practical way to maximize existing square footage without constructing a larger home addition.

How Much Does Building an ADU Cost in Manhattan Beach?
The cost to build an ADU in Manhattan Beach depends on the type and size of the ADU, existing site conditions, utility connections, material selections, and the amount of structural work required.
JADU (Junior Accessory Dwelling Unit): $60,000–$120,000
Garage Conversion ADU: $100,000–$200,000
Attached ADU: $180,000–$350,000
Detached ADU: $250,000–$500,000+
A garage conversion may cost less than building a new detached ADU because it uses an existing structure, while detached ADU construction typically requires a new foundation, framing, roofing, utilities, and complete interior construction.
These ranges are general planning estimates. During your consultation, we can evaluate your property, the type of ADU you want to build, and your project scope to provide a more detailed estimate.
How Long Does ADU Construction Take in Manhattan Beach?
ADU construction timelines in Manhattan Beach depend on the type of ADU, project complexity, permitting, site conditions, and whether you're building a new structure or converting existing space.
JADU (Junior Accessory Dwelling Unit): 2–4 months
Garage Conversion ADU: 3–6 months
Attached ADU: 6–9 months
Detached ADU: 8–14+ months
Permitting and plan review can add approximately 2–6 months to the overall timeline, depending on the project and required approvals.
Garage conversions and JADUs can often be completed faster because they utilize existing structures, while attached and detached ADU construction typically requires more extensive foundation, framing, utility, and construction work.
