Types of ADUs You Can Build in Lakewood
Detached ADUs
A detached ADU is a completely separate structure from your primary home, commonly built in the backyard or another available area of the property. It can include its own kitchen, bathroom, bedroom or living area, and private entrance.
Attached ADUs
Attached ADUs are connected to the primary home while providing a separate living area. Depending on the property and project, this may involve expanding the existing structure to create the additional space.
Junior ADUs (JADUs)
A JADU is a smaller accessory dwelling unit created within the existing or proposed space of a single-family home. It provides a compact option for homeowners who want additional living space without constructing a full-size detached unit.
Garage Conversion ADUs
An existing garage can be converted into a functional living space with the necessary structural work, insulation, utilities, windows, doors, and interior finishes.
How Much Does It Cost to Build an ADU in Lakewood?
The cost of an ADU depends on the type of project, size, existing conditions, utilities, finishes, and amount of structural work required.
JADU (Junior Accessory Dwelling Unit): $50,000–$100,000
Garage Conversion ADU: $80,000–$180,000
Attached ADU: $150,000–$300,000
Detached ADU: $200,000–$400,000+
A garage conversion may cost less than new construction because you're working with an existing structure, while a detached ADU typically requires a new foundation, framing, roofing, utility connections, and complete interior construction.
How Long Does It Take to Build an ADU in Lakewood?
ADU construction timelines vary based on the project type, size, design, permitting, site conditions, and scope of work.
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 can take approximately 2–6 months depending on the project and city approvals. Once permits are approved, the construction timeline will depend on the complexity of the ADU and the work required.
