What You Can Expect From Go ADU
120+ ADUs Built
We've completed 120+ ADU projects across Los Angeles, from garage conversions to ground-up detached ADUs.
Building ADUs Since 2017
Founder Gil Vaisman began building ADUs in 2017. Go ADU was founded in 2020 with a focus on ADU planning and construction.
Guaranteed Contract Pricing
Your contract price is based on a detailed scope of work established before construction begins. The goal is to give you a realistic number upfront rather than relying on allowances or unexpected charges later.
Milestone-Based Payments
You don’t hand over a large portion of your construction budget upfront. Construction payments are tied to completed project milestones.
Clear Communication
During construction, you receive progress updates, photos, and information about upcoming decisions so you know what is happening on your project.
What You Should Know Before You Hire an ADU Builder
An ADU is a major construction project. The contractor you choose will be responsible for your budget, your property, months of construction, city inspections, and hundreds of decisions along the way. It's worth it to look beyond the estimate.
You should know whether your contractor is licensed, whether they regularly build ADUs, how they structure payments, what happens when something changes, and whether past homeowners had a good experience working with them.
Go ADU gives you clear answers to those questions before you sign a construction contract.
Licensed to Build ADUs in California
California Contractor License #1076712
Checking a contractor’s license should be one of your first steps before signing a construction agreement.
Go ADU Construction operates under California contractor license #1076712. You can verify the license directly through the California Contractors State License Board.
But licensing is only the starting point. You should also ask whether the contractor regularly builds the type of project you’re planning.
ADUs come with their own challenges, including setbacks, utilities, Title 24 requirements, city plan checks, inspections, access constraints, and existing structures that may need to be incorporated into the project.
Go ADU focuses exclusively on ADUs, so our permitting workflows, construction systems, trade relationships, and project experience have all been built around this one type of project. That specialization helps us identify potential issues earlier, navigate common ADU challenges more efficiently, and give you more realistic expectations for cost, schedule, and construction before work begins.


120+ ADUs Across Los Angeles
Founder Gil Vaisman began building ADUs in 2017. Since then, Go ADU’s experience has grown to more than 120 ADU projects across Los Angeles.
That includes:
- Detached ADUs
- Attached ADUs
- Garage conversions
- JADUs
- Multi-story ADUs
- Custom ADUs designed around individual properties
Every property presents a different combination of zoning, site access, utilities, existing structures, neighborhood conditions, and city requirements.
Building ADUs repeatedly means our team has encountered many of those situations before.
If you’re starting without plans, Go ADU can manage design, permitting, and construction. If you already have approved plans, we can take your project through construction and final inspection.
Pricing Should Be Clear Before Construction Starts
Go ADU provides guaranteed contract pricing based on a clearly defined scope of work, so you know what your ADU will cost before construction begins instead of starting with a low estimate that grows as the project moves forward.
Before construction, we work through the plans, scope, and project details needed to establish your contract price. That gives you a clearer picture of the investment before work starts.
Your Payments Follow the Progress
Construction payments are tied to milestones. We complete the agreed work for a milestone. You verify the progress. Then the corresponding payment becomes due.
This structure means you aren’t handing over a large percentage of your construction budget before meaningful work has been completed.
If an unexpected condition is uncovered or you request a change to the project, we document it, explain your options, review the cost and schedule impact, and get your written approval before additional work moves forward.
Defined scope. Guaranteed contract price. Milestone-based payments. Written approval for changes.



Meet Gil Vaisman, Founder of Go ADU
Gil Vaisman grew up around construction as the son of a developer. He began building ADUs in 2017 and saw firsthand how much usable space and property value could be created on lots homeowners already owned.
Go ADU was founded in 2020 with a dedicated focus on accessory dwelling units.
Today, Gil leads business development alongside a production team that includes Hugo Ruiz, a second-generation builder with more than 20 years of construction experience. That experience shapes how we approach the early conversations about your property.
Sometimes the answer is that your property presents a strong ADU opportunity. Other times, there may be site conditions, costs, or limitations you should understand before moving forward. Our job is to give you the information you need to make that decision with a realistic understanding of the project.
What Homeowners Say About Working With Go ADU
5.0 Google Rating | LA’s Recommended ADU Builders
We had a beautiful experience working with Gil’s team of Hugo and Daniel and they were very diligent throughout the entire process. They built our ADU from start to finish in less than 6 months all while my elderly 77 year old dad lived in the front house and they showed great consideration to him. The finishes were on point and the communication never lacked with Gil and Daniel always picking up the phone when we called. And one of the most impressive features of our experience is that for a six figure project the price we were given is the EXACT price that we paid at the end. Would definitely recommend Go ADU to take the stress out of building in the City of LA
Just finished an ADU build with Go ADU and I’m genuinely impressed with how they ran the job. Anytime something unexpected popped up—city, utilities, you name it—they told me right away and laid out options instead of just dumping problems in my lap. Communication was steady the whole way through, and I never felt like I had to chase them for updates. The unit turned out exactly how I pictured it: clean lines, solid workmanship, and ready to move into. I’d gladly bring them back for another project.

Gil and his amazing team just completed my ADU project in less than five months. I am extremely satisfied with their promptness, work ethic, and the quality of the job. There is no guessing or sugar-coating in his business. As I was researching my options on Yelp before working with Go ADU, I read the reviews about Gil but found them a bit unrealistic and market-pitched.

We hired Go ADU, with Gil as the owner and Hugo as the project manager, to design and build an ADU for us, and we’re so happy with how everything turned out. From day one, they made the whole process easy to navigate. Gil was great at working through the design, helping us turn our ideas into a functional plan, while Hugo made sure everything stayed on schedule during the build. The communication between them and with us was seamless.
I really appreciated how clean they kept the site. We’ve worked with other contractors before, and this is something a lot of people overlook, but not Gil and Hugo. Their team was careful about cleaning up each day, and even after a huge rainstorm that made everything muddy, they had the site looking spotless by the next morning. Little things like that really made a difference.
The design process was another standout part of the experience. I had a general idea of what I wanted, and Gil helped bring it to life with practical suggestions to make the space both beautiful and functional. Hugo was fantastic at managing the day-to-day construction, making sure the project moved along smoothly and keeping us updated at every stage.
If you’re looking for a team that’s professional, reliable, and easy to work with, I’d definitely recommend Go ADU. They made the entire process so much less stressful, and we love how the ADU turned out!
I couldn't be happier with the work Go ADU did on my garage conversion. They were professional, efficient, and communicated every step of the process. The finished product is stunning, and I've already rented it out! The fact that they finished on time was a huge relief. If you're considering an ADU project, I highly recommend them.
I recently had the pleasure of working with Go ADU on my ADU project. From start to finish, their team was incredibly professional and efficient.

I would highly recommend Gil and Hugo from Go ADU to anyone considering building an ADU. Their attention to detail and commitment to a clean workspace made the entire process a breeze.
I just wrapped up an ADU project with Go ADU, and I’ve got to say, I’m really happy with how it turned out. They kept the site super clean, which isn’t always the case with contractors. Plus, they actually finished on time. There were a couple of hiccups, but they were quick to let me know and always had a plan to keep things moving.
The final result looks great—exactly what I was hoping for. Solid work all around. Definitely someone I’d work with again.
I don’t often leave reviews but Gil and the team did an awesome job on our ADU. We vetted a couple contractors and chose Gil as he was very personable and we wanted to enjoy the experience of the build as we had heard some horror stories. Go ADU did a fab job, and we’ll be recommending them to friends and neighbors. We’ll be renting our ADU and here are the photos from our staging! Thank you Gil!!!
Gil, Hugo and the entire Latino fleet of GOADU are simply remarklable! They made my dream into a reality. And made a highly expensive task become cost effective!!! I am now a proud owner of garage converted ADU! If you are on a tight budget but still adamant at pursuing of owning an ADU. Gil of GO ADU is the answer! Feel free to check them out and find out for yourself how Gil can work magic on your dream!
I've built several ADUs now with different contractors and this one was the easiest and smoothest to date thanks to Gil and his team at Go ADU. Communications was great throughout the process and most impressively, Gil's team actually stuck to a schedule and on the few occasions where we had to deviate, we were only off by a few days rather than weeks or months on my previous jobs with other contractors. Gil was also very responsive and accommodating to change orders and corrections -- no fuss, no pushback. Am definitely going to recommend him to other clients and investors of mine!
Hiring Go ADU for my project was finding a gem in a sea of contractors. From day one, they had a game plan that made sense and kept the project on track.
Their transparency was refreshing. No smoke and mirrors—just clear communication about timelines and costs that helped me plan ahead without any surprises.
But what really stood out was how they listened. They didn't just build; they collaborated, taking my ideas and turning them into reality.
I'm grateful for a stress-free build process, look no further than Gil, Hugo and their team.
I want to recommend Go ADU. They did a great job getting our project done. Helped us design and build.
I’m a long time real estate investor and I’ve worked with at least a dozen contractors. Gil and his team are by far my favorites. They’re the most reliable contractors I’ve ever worked with. Communication was superb — clear, realistic timelines and constant updates with photos. He and is team were highly skilled in understanding the nuances of my project. I’m thrilled with the final product and will absolutely be using GoADU again for my next project.
Gil fixed up my ADU after a nightmare contractor couldn’t get it finished according to code and kept failing inspection. He walked off the job and I was overwhelmed because construction wasn’t my lane of expertise. Gil knew how to communicate with us as a homeowner himself. He understood our point of view, was knowledge and helpful, and got the ADU finished and permitted.
Go ADU provided transparent pricing and transparent timelines. Gill provided a realistic timeframe and included detailed estimates from soup to nuts. So happy to have gone in this direction. A+++
If you want a no-nonsense, get-the-job-done ADU contractor in Los Angeles, look no further than Gil and GO ADU. Their team is all about delivering results with great communication. They listened to my needs, provided a clear plan, and executed flawlessly. There were no surprises, no delays—just quality workmanship and exceptional service. I wouldn't hesitate to recommend them to anyone in need of reliable ADU construction services.
