Worked very closely with Millie and team on a remodel of our 2000 sq feet property in Milpitas and it was a delight to work with Millie and the entire team. Millie took the entire burden off of our shoulders and had her team do some amazing work and a very tight schedule. The work the team has pulled off is amazing and we are extremely happy with the work and looking forward to moving back in.

We recently completed a renovation project with GADI Construction, and I couldn't be happier with the results and service.
From the very beginning, the team truly listened to our vision. They are incredibly flexible and capable of customizing everything to meet specific needs–no matter what idea we threw at them, they always found a practical, creative way to bring it to life. On top of their top-tier craftsmanship, their pricing was very fair and transparent throughout the process.
A special shoutout to our project manager, Nadav, who was exceptional. Nadav's attention to detail is unmatched. He handled all communication with the crew effortlessly and was constantly proactive with quality control, catching and resolving small details before they ever became issues. Because of his dedicated management, I was able to stay focused on my own work and personal life without the typical stress that comes with remodeling.
If you are looking for a reliable, customer-focused contractor that delivers top-quality work at a fair price, I highly recommend GADI Construction and Nadav!
I requested a consolidation to replace our kitchen countertop/ backsplash/ sink. Itay from GADI, did a wonderful job explaining the project process, suggesting different ideas, cost and timeframe.
Thank you Itay!

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..

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.
