Why the Bay Area Chooses Gadi Construction
The GADI Team worked with us in multiple renovation projects. They quickly scoped and executed the project within the budget. Job well done!

Beautiful job updating the kitchen and shower. Our project manager, Eden was responsive and quickly moved the project along, completing everything in three weeks .
GADI did a great job updating our kitchen and shower.
Our project manager Eden was highly responsive, quickly understood exactly what we needed, and kept everything moving efficiently. The entire project was completed in just 3 weeks. Updating the kitchen included installing a new counter, a new sink, and a built-in dishwasher, and everything is beautiful and working well. They also painted the cabinet doors, greatly improving the look of the kitchen. For the bathroom, they removed a built-in bench, making the shower much more spacious, and beautifully replaced with new tiles, including the floor.
We just completed a full primary bathroom remodel with Gadi constructions and we could not be happier with the result. The quality of the work was excellent, the project was well managed, and the finished bathroom turned out beautifully and almost exactly to the vision I had in mind.
I especially want to recognize Millie, our program manager, who was exceptional from start to finish. Her enthusiasm for her work is infectious, but what impressed me most was how personally invested she became in getting every detail right. She approached the project as though she were working on her own bathroom, not a client’s. She was constantly thinking ahead, finding creative solutions, making things work when challenges came up, and never settling for “good enough.”
I traveled quite a bit during the remodel, and knowing Millie was overseeing everything gave me tremendous peace of mind. She kept the project moving, handled issues without creating unnecessary stress for me, and always made me feel that the details were in very capable hands.
Remodeling can be disruptive and stressful, but having someone who genuinely cares about the outcome makes all the difference. Millie went above and beyond in every sense, and the entire team delivered a bathroom we absolutely love. I would highly recommend them.

Gadi construction handled the remodel of my 2 bathrooms: the main and secondary. My project manager Eden was the reason I chose them, she was responsive and listened to what I needed. She guided me through the process and helped me choose the right materials. They were not the lowest quote but I felt I was going to get my project done on a timely schedule and completed to my liking. And we are thrilled on how they came out! Thank you Eden!

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.
