Written for homeowners, by local experts in Los Gatos

Across the Bay Area, homeowners are turning to Accessory Dwelling Units (ADUs) to add value, flexibility, and income potential to their properties. Whether you’re interested in a backyard ADU, converting a garage to an ADU, or creating a modern granny flat construction, the right ADU builder can make all the difference in your project’s success.

At EDR Design Build, we specialize in delivering custom ADU designs that comply with California ADU regulations while maximizing space and style. Here’s what you need to know before starting your project.

Why Build an ADU in the Bay Area?

The demand for ADU homes is higher than ever, and for good reason. Building an ADU offers:

Rental income potential through long-term or short-term leases
Private living space for family members or guests
Increased property value in competitive Bay Area markets
Sustainable housing options that maximize existing lots

Whether you’re in Los Gatos, San Jose, or another Bay Area community, ADUs provide both lifestyle and financial benefits.

Choosing the Right ADU Builder Near You

Not all ADU builders are the same. When evaluating contractors, look for:

Experience with ADU floor plans and space-efficient layouts
Knowledge of ADU zoning regulations and permitting in your city
A portfolio of completed projects, from garage conversions to detached ADU houses
Transparent guidance on ADU cost and financing options

At EDR, our design–build approach ensures your accessory dwelling unit design is both functional and beautiful.

Types of ADUs You Can Build

Depending on your property, lifestyle, and budget, you can choose from several ADU types:

Detached Backyard ADU – A stand-alone structure with full privacy
Garage Conversion ADU – An affordable way to transform unused space
Attached ADU – Connected to your main house but with separate entry
Second-Story ADU – Built above a garage or home addition for extra space

Each option comes with unique design considerations and permitting requirements, which our team navigates for you.

How Much Does an ADU Cost?

The cost of building an ADU in the Bay Area varies depending on size, finishes, and complexity. While detached ADUs tend to be more expensive, they also deliver higher long-term value. Working with an experienced ADU contractor ensures your project stays on budget while meeting all local building codes.

Financing and Regulations

From ADU financing options to understanding California’s ADU laws, navigating the process can be overwhelming. Cities like San Jose ADU programs offer streamlined approvals, but requirements differ across municipalities. At EDR, we guide you through compliance so your project moves forward without costly delays.
