Why the Bay Area Chooses Gadi Construction
I had a very good experience with Millie personally and the whole Gadi team doing a major kitchen renovation , that included designing the kitchenrelocations, skylights and reconfiguration of space.
I will gladly recommend to work with them. I personally plan to do so in the future.

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.

The cost to build a 1200 sq ft ADU in California varies significantly depending on the location, materials, and design complexity. In the Santa Clara CA and San Jose CA area, you can generally expect a price range of $250 to $400 per square foot for a custom build. This means a 1200 sq ft unit could total between $300,000 and $480,000. However, these figures are for new construction and do not include permit fees, utility connection costs, or site preparation. For a more accurate comparison of building methods, we recommend reviewing our internal article titled 'Prefab Vs. Custom ADUs: Santa Clara Cost Analysis' Prefab Vs. Custom ADUs: Santa Clara Cost Analysis to see how different approaches affect your budget. Always consult with a local general contractor like Gadi Construction for a site-specific estimate.
The cheapest option for an Accessory Dwelling Unit (ADU) is typically a prefabricated or modular unit, as it minimizes on-site labor and construction delays. For homeowners in the Santa Clara CA and San Jose CA area, a junior ADU (JADU) is often the most budget-friendly choice because it can be created by converting existing space, such as a bedroom or garage, without requiring new foundation work. This approach significantly reduces permit and material costs. For a deeper look at maximizing value during a garage conversion, we recommend reading our internal article titled 'Converting Your Santa Clara Garage Without Losing Value: The Ultimate 2026 Guide' at Converting Your Santa Clara Garage Without Losing Value: The Ultimate 2026 Guide. Always consult with a local professional like Gadi Construction to ensure your project meets city codes while staying within your budget.
When building an Accessory Dwelling Unit, common mistakes include underestimating the total budget, as many homeowners forget to account for utility connection fees, impact fees, and design costs. Another frequent error is failing to check local zoning laws and setback requirements, which can lead to costly redesigns. Poor planning for the site's drainage and grading often results in water damage issues later. Additionally, many people choose the wrong contractor without verifying their experience with ADU projects specifically. To avoid these pitfalls, we recommend reading our detailed guide, Santa Clara County ADU Planning Permission: The Complete 2026 Guide to Permits, Costs, and Regulations, which covers all the necessary permits and regulations for Santa Clara County. Proper upfront planning and hiring experienced professionals are key to a successful build.
For homeowners in the Santa Clara and San Jose area, selecting the right ADU company is a critical step. You should prioritize firms with a proven track record in local permitting and construction, as city-specific regulations vary significantly. A reliable company will offer transparent pricing and a clear timeline. For a detailed breakdown of financial considerations, we recommend reviewing our internal article titled Prefab Vs. Custom ADUs: Santa Clara Cost Analysis. This analysis compares the costs of prefabricated units versus custom builds, helping you make an informed decision. Gadi Construction advises that you always verify a company's license, insurance, and past project portfolio to ensure they meet industry standards for quality and safety.
