Types of ADUs Homeowners Can Build
San Diego ADU builders can build different types of accessory dwelling units depending on the property layout, budget, and long-term goals. Understanding the different ADU options helps you choose the design that fits your space, supports your lifestyle, and adds lasting value to your home.
Detached ADU
A detached ADU is a separate backyard structure with its own entrance, kitchen, and living area. It offers the most privacy and flexibility, making it ideal for rental income, guest housing, or multigenerational living.
Attached ADU
An attached ADU is connected to the main house but functions as an independent living space. It includes a private entrance, kitchen, and bathroom, giving homeowners extra living space while keeping the unit integrated with the home.
Above-Garage ADU
An above-garage ADU is built over an existing or new garage, creating a full living unit without using additional yard space. This option maximizes vertical space and works well for properties with limited lot size.
Junior ADU (JADU)
A junior ADU is a smaller unit created within the main home, often using an existing bedroom or section of the floor plan. It usually includes a compact kitchen and provides a simple way to add a flexible living space.
