Custom Home Builder reviews in San Jose, California

We just finished building a 650 sq. ft. ADU in our backyard, and I have to say, working with ADU Builders Bay Area was an incredible experience from beginning to end. We had been considering adding more space to our home for quite some time, and once we decided to move forward, this team made everything feel so manageable.
They were super easy to talk to and came up with some fantastic ideas that we hadn’t even considered. Everything was completed in line with code and HOA requirements, and I really appreciated how respectful they were towards our property and our neighbors. The crew kept the area tidy throughout the build, which was a huge relief since we were still living there.
The finished ADU looks stunning,modern, cozy, and way more polished than we ever expected. I’ve already recommended them to a few friends, and if we ever decide to take on another project, I wouldn’t hesitate to call them again!

My parents decided to build an ADU in our backyard, and they decided to go with ADU Bay Area. Because my parents are not tech-savvy and are unable to write reviews, I have to do it for them.

I have to say, I loved the entire process. The team was with us step by step from the initial consultation to the last walkthrough, and they were great. My mother was the most relieved when the business took care of all the permits and paperwork, as this was her biggest stress.

The actual construction was faster than even we had anticipated. The crew was honest, respectable, and there was no mess left behind. My parents loved the gorgeous modern studio. We've already received tons of compliments from guests, and it's such an added bonus for our property.

If you're in the Bay Area and thinking about an ADU, these guys are a great initial contact! They turned a potentially stressful project into something easy and seamless for my family. Thank you all so much!

Working with ADU Builders Bay Area has been a breeze from start to finish. They handled everything for my 1,200 sq. ft. ADU, from designing the layout to getting me through the permitting process. Their expertise made a huge difference because of their planning, the city approved my project in 45 days with no revisions.
They introduced me to the right people, like land surveyors and soil engineers, and everything was smooth sailing. Communication was top notch,they were always available to answer my questions and keep me in the loop.
Now a month after completion I can say the finished product is better than I expected. The ADU is beautiful, functional and built with quality.

Last month, I finished building an ADU with ADU Builders, and I couldn’t be happier with how it turned out. From the start, the entire process was smooth and well organized. The team made everything feel easy, guiding me through each step and ensuring everything was handled with care.
The quality of the materials they used was good, you can tell they don’t cut any corners. Every detail, from the finishes to the overall build, was done with precision. The ADU looks amazing and blends perfectly with the main house. It’s already added so much value to our property, and I know it’ll be a great space for years to come.
What I really appreciated was how communicative and responsive the team was. They kept me informed throughout the project and made sure all my questions were answered. Now that it’s complete, I’m so thrilled with the result. Thank you guys!

We recently completed our attached ADU construction and I genuinely have nothing but praise for ADU Builders Bay Area. The team made everything seem simple and stress-free right from the start. Everyone with whom we came into contact was exceedingly patient, kind, and sincerely interested in ensuring that we were satisfied with the result. From permits to finishes,literally down to the cabinet hardware, the team managed the entire project, and the outcome is stunning. It looks so professional, like something you'd see in a design magazine, that a number of our neighbors have asked to take a look inside.
They brought in expert cleaners after the project was finished so we could start using the space right away, which was an unexpected but much appreciated touch.

I own a small design firm out of my house, and operating from my kitchen table was no longer feasible. I considered freestanding office pods, but they were far too expensive and not code compliant. I was referred to ADU Builders Bay Area by a friend, and got quite far along in the process with them.

They worked with me to create a little studio with a half-bath and large windows for natural light. I didn't need to create anything fancy, but the team made recommendations that made the space workable and aesthetically pleasing — and all within budget. I particularly appreciated their responsiveness. If I had a question, somebody actually called back the same day.

Now I finally have a real office area that also serves as a bedroom when relatives come to visit. And the best part? It added more value to our property than I ever thought it would. Would strongly suggest them to anyone considering putting in an auxiliary unit.

We recently finished building a small ADU in our backyard for my mother-in-law. We partnered with ADU Builders Bay Area, and the entire process was much smoother than I had anticipated. Nick, our project manager, was exceptionally organized and ensured everything stayed on track. From our initial meeting, he provided clear explanations and was easy to communicate with throughout. Sergio, the designer, truly impressed us. We came with some inspiration photos and varied ideas, yet he crafted a design that was both functional and cozy, making great use of our backyard. He offered suggestions we hadn't considered, and his focus on detail was evident in the final outcome. I often find myself worrying and overthinking, but the team remained patient and kind during the process. They answered all my questions without rushing me. Now that the ADU is complete, my mother-in-law is settled in and loves it. Honestly, I couldn't have asked for a better team. If you're planning a similar project, I wholeheartedly recommend ADU Builders Bay Area.

We had a wonderful experience with ADU Builders Bay Area! We started with plans from another company, but they didn't make the best use of our space. So, we turned to ADU Builders Bay Area for a redesign, and it was the best decision we made. The new design transformed the space, making it feel larger, more open, and much more functional. From the first meeting, the team was professional and knowledgeable. They focused on getting every detail right, offering great ideas for maximizing space. They were always ready to answer our questions, whether they were about the design, permits, or construction. Now that our ADU is built and has passed its final inspection, we couldn’t be happier with how it turned out. It went beyond our expectations, and we're thankful to ADU Builders Bay Area for their skills and dedication. If you’re looking for a team that truly knows how to bring an ADU project to life, this is the company to go with!

We started an ADU project in San Rafael but encountered septic system restrictions that most contractors wouldn’t tackle. ADU Builders Bay Area stepped in, rerouted the plumbing layout, and gained county approval within two months. What started as a headache became manageable thanks to them. The unit is small but functional and fits well with our landscape.

I own a rental property and was interested in building an ADU in my backyard to create better use of the space. After hearing wonderful things about ADU Builders Bay Area, I decided to give them a call, and I am really glad I did. A friend of mine had had experience working with the team and highly recommended them.
From the very first meeting, Olive explained the entire process crystal clear. She connected me with great architect and engineer to design the perfect plan and take care of city approvals. When Serge finished the 3D design and plans, himself and his crew started work.
Now that my ADU is complete, I am happier than I could imagine. This space is better than I could ever have imagined, since a few friends are still occupying it until my new tenant settles in. The whole process was smooth sailing, and Mark's professionalism and dedication stood out. If I had another project, ADU Builders Bay Area would be my first and only call.

We built a rental ADU in San Jose with ADU Builders Bay Area. The permit process held us back for months, but once we hired them, things finally started moving. They resubmitted plans, coordinated with the city, and got us approved. Construction went smoothly, with only brief weather delay. The unit is still under construction but I can tell it will be functional, and blends well with our house. I bet the rent will covers almost half our mortgage.

For a long time, my husband and I had been looking into real estate investing, but because of housing prices in the Bay Area, it seemed like a distant dream to purchase a second home. We even ran the numbers to see if we could do a cash out refinance on our current home to use as a downpayment. However, it just didn't make sense — especially if we were borrowing 100% on the new home.

That is when we started looking into the possibility of building an ADU as an alternative. After a lot of research, we came across ADU Builders Bay Area, and it was greatly appreciated that they had a no-money-down option. This was really the perfect solution for us.

The group completed the work on schedule and with the utmost professionalism. Every day, they tidied up after themselves, which allowed us to continue using our backyard. They also assisted us in putting up a fence to provide us and the ADU some extra privacy, which turned out to be an important and great detail.

They were a pleasure to work with, and the whole experience was very positive. If you need a dependable and professional team that works rapidly and pays attention to the details, give them a call, I have no hesitation in recommending them.

Working with ADU Builders was such a smooth and positive experience! The entire process, from start to finish, was handled professionally and with great care. Our project manager, Nick, was amazing and he kept everything on track and made sure we were always in the loop. What stood me out the most was how stressfree they made the whole construction process feel, even with all the details involved.

Now that the project is finished, we’re beyond happy with our new ADU. It’s beautifully done, and we’re excited to have my mom move in soon. If you’re thinking about building an ADU, I can’t recommend ADU Builders enough. They really know their stuff!

I spent months trying to understand the city’s permit rules on my own but made no progress. ADU Builders Bay Area stepped in and explained everything clearly. They handled the drawings, submissions, and scheduled inspections. I really like the vaulted ceiling they suggested. The project finished close to the timeline we discussed, and I didn’t feel shocked by the costs.

We've just completed our garage conversion with ADU Builders Bay Area, and I'm still in awe of how seamless the whole process was. What began as a simple concept—a basic one-bedroom ADU—turned into something so much more for our family, and that's all thanks to their team.

Naturally, there were a few things that we did not anticipate (some weather delays and permit surprises), but the crew consistently kept us informed and worked around them without issue. I was particularly impressed that even on weeks when there were horrible storms, they continued to work on the project without missing a step.
Everyone we interacted with was polite, professional, and communicated effectively—no hard sell or open-ended timetables, just honest work and an open schedule. The finished ADU is beautiful and already feels at home on the property.
Huge thanks to the fantastic team for making what was potentially a stressful project feel so manageable. We are absolutely delighted with the result and would highly recommend them to anyone who is going to build.

We picked ADU Builders Bay Area to build our backyard ADU because they seemed experienced and easy to work with.
They helped us design a comfy 2-bed, 2-bath ADU, showed us detailed 3D models, and handled permits quickly. It took 1 month for approval and they kept us updated.
Construction took six months, and we passed inspection two months later. The team was responsive and the work was great.
4 months later, we're still happy. When we had an insulation issue after a storm, they fixed the wall with no extra cost. Their quality and customer service are great!

This was my first time dealing with a construction project, and I'm really glad I chose ADU Builders Bay Area to help me out. They made everything so easy, from the planning stages to revising designs and handling the permitting. The team was quick to answer my questions and shared great tips along the way. Their know how made everything go a lot smoother. My ADU plans got approved with just a few tweaks, and they made sure to submit any changes to the county well ahead of time. Communication was always clear and regular throughout the process.
Now that the ADU is done, I couldn't be happier. I built it for my mom since I moved her closer to me from another state. I'm really thankful for such a hassle-free experience, and I’d definitely recommend ADU Builders Bay Area to anyone thinking about an ADU project. I'm looking forward to working with them again on future builds.

While we were negotiating with a few builders, we decided to have a contract with ADU Builders Bay Area as we got the best deal with a guaranteed win situation. The builders were flexible with our budget and customized the builds to our needs.

The ADU Builders team kept us updated with the progress on the permits, and every step going forward. Each builder, from the project manager to the designers, was professional and attentive. Hopefully, the project manager kept the workstreams in sync and presented a neat site to us. We really appreciated the design team on the completed work by Mia, excellent. Overall, the team was pleasant and the ADU was completed to high standards. For these reasons, we definitely would recommend this company.

I hired ADU Builders Bay Area to turn our garage into a one-bedroom after spending months attempting to understand San Jose's permit regulations on my own. They took care of the drawings and submittals, informed me before each city inspection, and broke down the entire procedure in simple terms. After permits were granted, construction proceeded steadily. The built-in shelves they recommended for the bedroom are my favorite feature and they surprisingly make the small area work well.

I wanted to build a small rental ADU to help cover my mortgage costs, but I was worried about getting lost in the complexities of permits and inflated quotes. ADU Builders Bay Area helped me plan an efficient unit that maximizes natural light and minimizes the footprint to avoid triggering hefty impact fees. They explained that the return on investment typically reaches around 60% in this area. Permits took a while due to city scheduling, but they kept me updated with weekly emails. Now it’s rented, helping with my mortgage payments. They delivered solid work and offered smart guidance.

We have gone back and forth for a while whether it's worth it practically and financially to put in an ADU. After a few consults, we decided to go ahead with ADU Builders Bay Area and looking back, we are so happy we did.
From the beginning, they were clear, organized, and supportive. Andrew, our ADU consultant, was great at laying things out in simple terms and estimates on what kind of return we could expect. Once our project kicked off, our project manager kept the project on track, and the crew was courteous, friendly, and efficient.
What stood out to us was how well they communicated. They set up a group chat so we were always looped in and knew what to expect at every phase. Overall, it put our minds at ease and it was far less stressful than we thought it would be.
The actual build finished faster than we expected and the quality of the finished ADU has really surpassed our expectations. It looks amazing inside and out. We are already reaping the benefits of having it, and it adds real value to our property.
