Why the Bay Area Chooses Gadi Construction
Our home remodeling project is finally complete (almost 2 year ordeal), but team at Gadi Construction made this navigation manageable.
First shout out to Millie Studnict(Project Manager) . If you've ever gone through a major home renovation, you'd have many questions, decisions, surprises, inspections, and frustration. Throughout the entire process, Millie was always there with an answer, a solution, or simply the patience to walk us through the next step.
What I appreciated most was that Millie genuinely cared. No matter how busy things got, she always returned calls, responded to emails, and kept us informed. There were plenty of times when we were unsure about something, and Millie never made us feel like we were asking too many questions.
The entire Gadi team was great to work with as well. The crews showed up when they said they would, treated our home with respect, and were always courteous and professional. It was clear that everyone took pride in their work.
After dealing with the stress of restoring our home following a fire, it was a huge relief to have a contractor we could trust. The project is now complete, the final inspection has passed, and we're very happy with the outcome.
Thank you, Millie and Lucie and everyone at Gadi Construction..

Had a great full bathroom remodel. Went very smoothly and our project manager, Itay, was always quick to respond and on top of things. He was very helpful and efficient. We are very pleased with the finished project and will definitely reach out to GADI for our next project.
I just wrapped a primary bathroom remodel with GADI.
Effie was a fantastic design partner – he understood our initial vision and worked with it to come up with something even better that we love.
Nadav did an amazing job managing the project. Communication throughout was constant & immediate via text, and we got the project done quickly and with minimal fuss. His team on the ground was also great across the board.
I'm hoping to work with Nadav & Effie on another project soon, and I highly recommend GADI!

I requested a quote for a job I need done and I had the pleasure of meeting Itay today. He was very professional and kind. Had good energy and reassured me that he will do everything he can for the best outcome. This is more of a review on Itay and I will update if I decide to hire them. But the initial process of getting a quote done was great because of Itay.
I recently hadflood damage to my home which requires extensive remodeling. I called a number of contractors And I was most impressed with Millie from Gadi construction.
Though we haven't gotten to the point of actual construction yet , Millie has come out and given me excellent guidance for remodeling bathrooms, kitchen, living area. I've never done remodeling before so it was nice to have somebody like Millie to
' hold my hand,' and take some of the stress off of making some major decisions. She has since returned phone calls promptly and feels more like a friend helping me rather than a person I hired or may hire.
Whether we use you or not in the end thank you Millie for helping me during this difficult time and I hope others see this review and can take advantage of your nice , kind personality and expertise.
Great experience with Gadi on my bathroom remodel. He hired experienced sub-contractors and made sure they showed up on time. Pricing is fair for the work done.
GADI had helped me in demolishing a big mirror wall and remodeling it into a dinning room. I couldn't be happier with the result. Esther and her crew were just amazing and made my dream came true. Great job!

The $40,000 grant in California for ADUs refers to the CalHFA ADU Grant program, which provides eligible homeowners with up to $40,000 in financial assistance to help cover the pre-construction costs of building an accessory dwelling unit. This grant is intended to offset expenses like architectural designs, permits, soil tests, and impact fees. It is a forgivable loan that does not require repayment as long as the homeowner occupies the property for a specified period. For homeowners in Santa Clara and San Jose, this grant can significantly reduce the upfront financial burden of adding an ADU. At Gadi Construction, we recommend verifying your eligibility with a local lender or housing authority before proceeding with your project.
The cost to build a 1000 sq ft ADU in California varies significantly based on location, design, and materials. In the Santa Clara CA and San Jose CA area, a custom build typically ranges from $300 to $500 per square foot, placing a 1000 sq ft unit between $300,000 and $500,000. This estimate covers foundation, framing, utilities, and finishes but excludes permits and site preparation. For a more precise financial comparison, our internal article titled 'Prefab Vs. Custom ADUs: Santa Clara Cost Analysis' provides detailed breakdowns. You can access it here: Prefab Vs. Custom ADUs: Santa Clara Cost Analysis. Gadi Construction recommends budgeting an additional 10-15% for unexpected site conditions. Always consult local zoning rules, as fees and impact costs in Santa Clara County can add $15,000 to $30,000 to your total project.
