What happens on the call

Twenty minutes. Three questions. A straight answer.

No slideshow, no pressure. A specialist who has walked hundreds of California lots asks about your family and your property, then tells you what is realistic.

1

We listen

Who is the home for? A parent, an adult child, a renter, your own downsizing? That decides everything else, so we start there.

2

We learn about your lot

Setbacks, utilities, access, and your city's ADU rules. We read your property against them before anyone talks about a number.

3

You get a real path forward

What are your options, what kind of investment are you looking at, and clear next steps to make your project a success.

What homeowners build

A home in your backyard, built for the people in your life.

Single-story Acton ADU with covered patio

Keep parents close

A step-free, single-level home where Mom or Dad keeps their independence and you are thirty feet away. Often less than a year of assisted living.

Bright open-plan Acton ADU interior

Give kids a place to land

A real home for an adult child starting out, saving for their own place, or raising your grandkids next door instead of two hours away.

Add income and value

Rent it for a season of life, downsize into it later. A well-built ADU adds appraised value to the property and appreciates with the rest of your home.

What homeowners say after the build.

Rated 5.0 on Google by Bay Area families who have been through the whole process with us.

★★★★★

"Putting an ADU in your backyard is no small decision. I vetted 3 companies before making my final choice and frankly I could not be happier."

Harwood Family, Redwood City
★★★★★

"For an ADU, the way to go is with Acton ADU as they design-build the project and work through all the permit hurdles. There are just too many details to work through that need the expertise of an org such as Acton ADU to get things done well."

Maclaren Family, San Jose
★★★★★

"From the beginning, the process was easy and straightforward. The whole team was professional and communicative, which made me feel confident throughout the design, permits, and build."

Quigley Family, Downtown San Jose

Before you book

What does the consultation cost?

Nothing. It is a free 20-minute call with no obligation. You will not be asked to sign anything or commit to anything on the call. This is about you, your needs, and learning clear next steps.

Do I need to know what I want yet?

No. Most homeowners come to us with a property or a person in mind, not a vision for a floor plan. Tell us who the home is for and we will walk through the rest, including whether a Build Ready plan or a custom design fits better.

Can I actually build on my lot?

In most cases, yes. California law requires cities to allow ADUs on most residential lots, but size, placement, and utility details depend on your city and property.

Where do you build?

Santa Clara, San Mateo, Alameda, and Contra Costa counties, and the San Gabriel Valley, Westside, and Central Los Angeles.
