ADU Builder in Southern California

We know well that building an ADU in Southern California is more than just laying down concrete, nailing down wood and painting some dry wall. It’s about making a space that really works for you and those you care about. We’ve been building ADUs all over Southern California: from Sun Valley to Orange County and Granada Hills to Altadena, and everywhere in between. Along the way, we’ve learned that every project tells a story. That’s why we love to tell the story of our client’s projects in our portfolio section. Go ahead and take a look.

But our story, started six years ago. Gil and Oren, the “GO” in Go Builders, saw how much people distrusted contractors and felt it didn’t have to be that way. So, they built a company around two simple ideas: communicate honestly and do what you say you’re going to do. It’s that simple.

That’s still who we are today. Whether you want a rental unit, a guest house, or an art studio, we’re here to guide you through the process with transparency and respect. No surprises, no headaches. Just a team that’s as invested in your ADU as you are. Let’s build something great together. Pick your city and learn about how we can help.
