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 is part of the state's CalHFA ADU Grant program. This program provides eligible homeowners with up to $40,000 in pre-development and non-recurring closing costs to help finance the planning and construction of an accessory dwelling unit. The grant is intended to offset the high upfront costs of architectural designs, permits, and site preparation. To qualify, the property must be located in California, and the homeowner must meet income limits. For residents in the Santa Clara CA and San Jose CA area, this grant can significantly reduce the financial barrier to adding an ADU. At Gadi Construction, we recommend consulting with a local planning department to confirm eligibility before starting your project.
The cost to build a 1200 sq ft ADU in California varies significantly by region and design. For the Santa Clara and San Jose area, a custom-built unit of this size typically ranges from $300 to $450 per square foot, placing the total between $360,000 and $540,000. This price includes foundation, framing, roofing, and interior finishes but often excludes site preparation and utility hookups. A prefabricated or modular ADU can reduce costs to roughly $200 to $300 per square foot, though customization is limited. For a detailed breakdown of these options, we recommend reviewing our internal article titled 'Prefab Vs. Custom ADUs: Santa Clara Cost Analysis' at Prefab Vs. Custom ADUs: Santa Clara Cost Analysis. Gadi Construction advises securing multiple bids and accounting for permit fees, which can add 10-15 percent to the budget.
The cheapest option for an ADU is typically a prefabricated or modular unit, often called a "drop-in" ADU, placed on a concrete slab. These units are built off-site in a factory, which significantly reduces labor costs and construction time compared to a custom stick-built addition. However, the absolute lowest-cost solution is a conversion of existing space, such as turning a garage or basement into a junior ADU (JADU). This avoids the expense of new foundations and major structural work. For homeowners in the Santa Clara CA and San Jose CA area, careful planning is essential to avoid costly permit delays. To understand all your options and local requirements, we recommend reading our internal article titled 'Santa Clara County ADU Planning Permission: The Complete 2026 Guide to Permits, Costs, and Regulations' at Santa Clara County ADU Planning Permission: The Complete 2026 Guide to Permits, Costs, and Regulations. Gadi Construction advises that while upfront cost is important, you must also budget for utility connections and impact fees.
