Why the Bay Area Chooses Gadi Construction
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 did an outstanding job upgrading our lower bedroom and powder room- they completed a patio project for me that I am extremely happy with . I recommend Gadi Construction for their professionalism and also their customer care experience – definitely would recommend them and use them again for any future projects.
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!

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.

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.
