I was house hunting and looking for a lot large enough to accommodate an ADU. Val was so helpful and responsive, answered my questions, and even looked at satellite photos to see if an ADU was possible. I highly recommend consulting with Golden State if you’re considering an ADU build.

Robbin MaloneyTrustindex verifies that the original source of the review is Google. We were nervous at first (I mean, all the guys are young) but William made the design process so easy and appealing, we decided to jump in. We are very pleased with the result and the ADU looks great. Tony B.Trustindex verifies that the original source of the review is Google. These guys really took care of us from A to Z. They 100% made us feel like we chose correctly from day 1, especially after interviewing 10+ companies. Quality is wonderful and they really include everything in the price (expect permit fees of course) so you don’t have to supply anything yourself. They are very accommodating with any requests even during the build. My guy Eddie is super knowledgeable, always has the answers! Sam HusainzadaTrustindex verifies that the original source of the review is Google. Working with this ADU company was an outstanding experience from start to finish. Their team was knowledgeable, professional, and extremely communicative throughout the entire process. They helped guide the project every step of the way and made what could have been a stressful experience feel smooth and organized. The quality of work, attention to detail, and overall craftsmanship exceeded expectations. They stayed transparent with timelines, answered questions quickly, and truly cared about delivering a great final product. If you’re considering building an ADU, expanding your property, or adding value to your home, I highly recommend this team. Looking forward to working together again in the future. Carrie ReederTrustindex verifies that the original source of the review is Google. We were very satisfied with our experience working with Golden State ADUs! They truly are a one-stop shop - handling everything from design to construction with professionalism and care. The entire crew was amazing and took the time to clearly explain each step of the process. It was great working with one dedicated project manager who made everything smooth and stress-free. The quality exceeded our expectations. We highly recommend GSADU to anyone considering an ADU project! Peter ZomatTrustindex verifies that the original source of the review is Google.

They are very fair in pricing and their level of service is Top Notch. I highly highly highly recommend. Amazing people. Ask for val. Poway ImportsTrustindex verifies that the original source of the review is Google. I had the pleasure of building my parents adu by way of Val. And let me tell you, he was a class act. From the first meeting to the certificate of occupancy we had a smooth experience. Supper happy we chose them off a referral from a close friend. Thank you for everything! If you’re considering them, don’t hesitate, they are great. IlonaTrustindex verifies that the original source of the review is Google. It has already been several months since our ADU has been built. We are happy with the way it turned out. Nice quality work and good communication. Carly AmundsonTrustindex verifies that the original source of the review is Google. When we were preparing to build an ADU for my grandmother on a new property, we quickly realized how overwhelming the process could be. We were trying to piece together information from multiple sources, and it all felt confusing and unclear. Connecting with Val was our first real sense of clarity. It was so refreshing to speak with a real person who could offer direction. Val was incredibly helpful, responsive, and quick to arrange for someone to come out and survey our space. Unfortunately, due to the limitations of our lot, we needed to pursue an attached ADU in order to make everything work, which meant we couldn’t move forward with Golden State ADU. But from the moment we started working with their team, everything felt easier. They answered our questions promptly—which was especially important as we were nearing the end of escrow and needed confidence that building would even be possible. Even though we weren’t able to continue with them, we had such a positive experience. I especially appreciated that they have in-house engineers and a permitting team—it’s clear they’re well-equipped to navigate the complexities of the process. Thank you all so much for your time, support, and professionalism. Bunny ParkerTrustindex verifies that the original source of the review is Google. Jason was amazing and very professional. He arrived on time and answered all of our questions. Although it wasn't going to be a right fit for our yard, he told us our options and who to contact moving forward. A+++++ service, give them a call!!!
