Custom Home Builder reviews across the US

We decided to build an ADU for my sister, who just moved back to California. She wanted a bit of privacy, and we wanted to keep the family close. ADU Builders Bay Area helped us create a floor plan that worked for both the property and her needs.
The design phase was collaborative, and they patiently handled our changing ideas about layout. Construction had its bumps and there was a delay with a some delivery, but they adjusted the schedule to keep things on track.

What I appreciated most was the transparency. There were no hidden costs, and no vague answers. The final product blends in so well with the main house that visitors think it has always been there. My sister moved in last month and couldn’t be happier.

I live in Southern California but built an ADU on my property in Los Altos. ADU Builders Bay Area set up a shared folder where I could see weekly progress photos and updates. There were two rounds of corrections from the city, and they handled both quickly without requiring me to fly up. I was concerned about managing a project from far away, but they made it surprisingly easy. My tenants moved in shortly after the final inspection, and everything has gone smoothly so far.

I approached this project strictly as an investment. The crew delivered on time and kept the financials clear. Their weekly progress reports were useful for tracking expenses against rental potential. The unit was completed to code, and I signed a tenant within two weeks of the final inspection. From a return-on-investment perspective, the process made sense.

As a civil engineer, I have a reputation for being a troublesome client. I know what I am talking about when it comes to construction, from load calculations to drainage plans to shear walls. I chose ADU Builders Bay Area for my construction, and it was not a difficult decision considering my other options, as most competitors were filled with technical blunders, while ADU was the only one with a solid first draft. Leo, my superintendent, had no concerns with me showing up with a laser level. He took the measurements and said, “Check this pour.” Or, “Want to see the rebar before we close it up?” He was running the site with a high level of engineering precision. When I questioned a specification of a beam, he swiftly retrieved the stamped engineer's report from his truck. This was not just construction; this was a collaborative firm for execution of a technical plan. Their subcontractors, to no surprise, were also top-tier. The electrician and plumber were intimately familiar with the codes. There was no other joy for a professional who can’t turn off their brain than collaborating with such a competent team. They value the science of construction just as much as the art.

My mother-in-law is in India. We’ve been trying to bring her here for years, but finding housing in reasonable proximity to us is a tough nut to crack and the immigration process is a snail’s pace. So when her visa finally arrived in our house last year, we had about six months to sort this out. Our house in Santa Clara is hardly big enough for the four of us in our household now.

So we decided to build our ADU in the backyard. I had a few builders that I looked into but a coworker said his Brother in Law at ADU Builders Bay Area were amazing. We met with the project manager which was Mike. We sat with him and went over all of the details that we had discussed. How long it would take, our budget and that our Mother In Law does not speak much English and likes to do things her way.

Mike listened. No hawking "our product" or making big promises. He asked what her needs would be, essentially asking a battery of questions about her expected habits and potential requirements. Will she be cooking much, will she need to say her prayers, and so on. We hadn't really thought of those kinds of things.

It took about 5 months. There was a bit of a hold up with permits, like 6 weeks, but Mike kept us in the loop about what was going on. Overall the guys were really nice. They worked around our schedule which was a big deal. My husband started bringing them coffee in the morning and they would catch up on everything that was going on.

My in law house in the back yard is finished. Its small, but fine. 500 square feet, one bedroom, a decent kitchen and a nice bathroom. Mother in law has been living there for 3 months now. She has her own space, her own kitchen for cooking what she wants, and visits us sometimes for dinner. Mostly we leave her be. She likes being left alone and seems content. She's started a small garden in the back yard now.

It was a family matter, not a financial issue. ADU Builders Bay Area captured our vision. They enabled us to be a family again. Thank you for your priceless work.

ADU Builders Bay Area totally turned things around for my family. When I lost my job during the pandemic, we had trouble keeping up with the house payments for like, two years. We used up all our credit and almost lost the house. Building an ADU was a last-ditch thing – we used my husband's retirement money, which was scary. But the finance folks helped us get it all set up right. The construction crew worked fast – they knew we didn't have much time. When our first renters (a nice family who'd lost their home in the fires) moved in, and we got that first payment, it was such a relief. We can chill out now, finally. The extra money covers most of our house payment. The ADU's really well built - it's all solid and good quality. They don't just put up buildings; they help people feel safe and secure.

Turning our garage into an ADU was quite the experience! After doing a ton of research, we chose ADU Builders Bay Area. We were a bit worried about such a big project, but they had a great rep and kept us in the loop the whole time, which made us feel good about going ahead.
Basically, we wanted to turn our garage into a small apartment with a bedroom, bathroom, kitchen, and living room. From the start, the team really listened to what we wanted and explained everything clearly. They paid close to what they did, making sure the ADU was both useful and looked great.
What I liked most was that they were flexible and willing to work with us. They let us fine-tune the design, making sure the final space worked well. They also did great work, and use great materials.
The communication was also spot-on the team. The team always gave us updates and took the time to come by and talk us through everything, which was super helpful. We felt like we were part of the team, not just customers. Now that it’s all done, we’re so happy with our new ADU, it’s even better than we’d hoped!
If you’re thinking about converting your garage, I highly recommend ADU Builders Bay Area. They really do a great job, and made the whole process a lot easier.We’ll definitely call them again!

The communication was good, the pricing was fair, and they finished the ADU pretty much on schedule. There were a few small items left to address at the end, but they came back quickly to fix them. Overall, it was a positive experience.

About 6 months ago, my hubby and I decided to build a 450 sq. ft. ADU in our backyard so that we could have a bit more space and freedom for our family. We discussed it with a few companies and landed on ADU Builders Bay Area—and we're absolutely thrilled that we did.The entire unit turned out great. It has everything we ever wanted: cozy bedroom, complete kitchen, bright living room, and even a laundry area with washer and dryer. It is a small unit, perhaps, but it feels so well-designed and snug. You can tell there was true thought put into the design and the details.
What actually made the experience so great was the staff. Anyone who came out to work on the project was courteous, professional, and clearly took pride in what they were doing. The materials and craftsmanship used were top notch, and we never felt like corners were being cut.
Now that it's finished, it's become one of our favorite things about the property. Whether or not we use it for visitors or as a rental down the road, we know it'll be a rad space. Big thanks to the whole team at ADU Builders Bay Area!

This company was wonderful to work with because they kept everything real. Right from the start, everything was as expected. Max, our sales guy, even told us how long the permits would take at the most. He was like, I’ll tell you the worst case scenario for permits, so anything faster is a bonus for you. And that is exactly how it was. We knew San Jose was going to take a long time with the permits so because we expected it, we were not stressed. Anna, the project manager, was extremely organized. She made a timeline for us on Google Sheets, and every Friday she would color code it. Green meant we were on schedule, yellow meant there is a possible delay, and red meant someone needed to do something because there was a stop. We never had to ask her for updates. When the entire country ran out of windows, she put a yellow line on our sheet and a note weeks before the window install was supposed to happen. The note explained the window situation and the new expected install date she had given us. We really appreciated how honest they were. I like that we were informed at every stage of the process. It made us feel in control.

It is very helpful to have systems that alleviate stress, especially when building things.

Our collaboration with ADU Builders Bay Area on our JADU project delivered an outstanding experience throughout its entirety. The team demonstrated expertise and professionalism while making the process appear effortless. Through their guidance we navigated the myriad regulations alongside permits and inspections to ensure all processes were executed correctly and with efficiency.
The element that emerged as most distinctive was the exceptional structuring of their methodological approach. Throughout the design phase they meticulously examined each detail to assist us in developing a layout that maximized our spatial resources. Throughout the construction phase they maintained their involvement to ensure adherence to the plans while responding to any queries that arose.
The project approaches its final stages and we find ourselves exceedingly pleased with the outcomes. Our vision became reality through ADU Builders Bay Area's work which leads me to strongly endorse their services.

We live in a standard San Jose neighborhood and needed more space for our growing family and my mother, who could no longer live alone. I contacted ADU Builders Bay Area and they offered us a detached two story ADU. The design phase was a partnership and they helped us pick a plan that fit our space needs without overtaking our yard. David as project manager was our direct contact, and we appreciated the weekly updates. There was a frustrating delay on custom windows, but David was upfront about the wait and the impact it would made and the other parts of the project which was appreciated. She has her own space now, and we have peace of mind that she’s close. The quality is good and the team was respectful of our space.

As first-time homeowners, the idea of building an ADU was challenging. We wanted to make a separate living space for a home office, and for future guests. The team at ADU Builders Bay Area deserve the credit. David walked us through every step, in plain, uncomplicated terms, at a comfortable pace, and was always willing to answer our questions. There was a small problem with flooring installation where we had a chipped tile. We mentioned it, and without any problem, they had the entire section redone within a week. The service was outstanding and the dedication to getting it right was remarkable. It created a beautiful space and it has helped increase the value of our property tremendously.

When we contacted ADU Builders Bay Area, the experience was completely different. From the very first call, their team was helpful, transparent, and willing to answer all our questions without any pressure. Nina took our address and, within a day, sent us a detailed report outlining the best ADU options for our lot, including size restrictions and layout possibilities.

Their pricing was competitive compared to other companies, and the entire construction process was handled smoothly from start to finish. They kept us updated regularly through email, which made everything so much easier. What we appreciated the most was how they prioritized our needs, offering great advice on how to maximize the rental potential of our ADU. Overall, working with ADU Builders Bay Area was a fantastic experience, and we’d highly recommend them to anyone considering an ADU!

When I received a notice for having a dwelling without a permit, I felt lost. A friend suggested I contact ADU Builders Bay Area, and I'm really glad I did. Handling county notices can be overwhelming, but their team guided me through each step, which greatly eased my stress. They managed everything, from creating plans to remove the unpermitted areas to designing a new ADU. The permits went through without any trouble, and during construction, they constantly updated me with photos and videos. My ADU is now complete, and I am truly happy with how it turned out. The work quality is exceptional, and it's clear they take pride in their craftsmanship. Having a trustworthy team manage the permits, paperwork, and construction was a huge relief. If you need a reliable company that genuinely cares about their clients, I highly recommend ADU Builders Bay Area!

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.
