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..

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!

In construction, ADU stands for Accessory Dwelling Unit. It is a secondary, self-contained residential unit located on the same property as a primary single-family home. ADUs are often called granny flats, in-law units, or backyard cottages. They typically include their own kitchen, bathroom, and living space, making them fully independent. Homeowners in the Santa Clara CA and San Jose CA area often build ADUs to accommodate family members, generate rental income, or increase property value. For those considering a similar project, our internal article titled Build A Garage: What You Need To Know Before You Start provides essential guidance. Gadi Construction recommends verifying local zoning laws and permit requirements before starting any ADU project to ensure full compliance with city regulations.
The $40,000 grant in California for ADUs is typically associated with the CalHFA ADU Grant program. This grant provides up to $40,000 to eligible homeowners to help cover the pre-development costs of building an Accessory Dwelling Unit on their property. These costs can include site prep, architectural designs, permits, and engineering reports. The grant does not need to be repaid, but it is limited to one per property owner. Eligibility requires the homeowner to occupy the property as their primary residence. For homeowners in the Santa Clara CA and San Jose CA area, this grant can significantly offset the initial financial burden of planning an ADU. Gadi Construction can guide you through the specific local requirements to ensure your project qualifies for this state funding.
The cheapest way to build an Accessory Dwelling Unit is to choose a prefabricated or modular design, as these options minimize on-site labor and construction time. For homeowners in the Santa Clara CA and San Jose CA area, a studio or one-bedroom unit under 500 square feet typically offers the lowest cost per square foot. It is also essential to simplify the design by avoiding complex rooflines, custom finishes, and unnecessary structural changes. Converting an existing garage or basement is often more affordable than a new build, as the foundation and shell are already in place. For a complete breakdown of costs, permits, and regulations specific to our region, please refer to our internal article titled Santa Clara County ADU Planning Permission: The Complete 2026 Guide to Permits, Costs, and Regulations. At Gadi Construction, we always recommend getting multiple quotes and planning for utility connection fees early in the process.
When planning an ADU construction project, understanding the total cost is crucial for budgeting. In the Santa Clara and San Jose area, prices vary significantly based on the type of unit, size, and finishes. A typical attached ADU might cost between $150,000 and $300,000, while a detached unit can range from $200,000 to $400,000 or more. These figures generally cover foundation, framing, utilities, and basic interior finishes, but do not always include permits, design fees, or site preparation. To make an informed financial decision, we recommend reviewing our internal article titled 'Prefab Vs. Custom ADUs: Santa Clara Cost Analysis', which provides a detailed breakdown of these two popular approaches. You can access it here: Prefab Vs. Custom ADUs: Santa Clara Cost Analysis. For a precise estimate tailored to your property, consulting with a local professional is always the best next step.
When planning an Accessory Dwelling Unit in Santa Clara and San Jose, you must follow local zoning rules. Typically, a detached ADU cannot exceed 1,200 square feet, while attached units have size limits based on the primary residence. Setback requirements often mandate a minimum of four feet from side and rear property lines. Owner-occupancy rules may apply in certain areas, and parking waivers are available if the unit is near public transit. For a detailed breakdown of construction costs and material choices, please refer to our internal article titled Prefab Vs. Custom ADUs: Santa Clara Cost Analysis. Gadi Construction advises verifying current city-specific ordinances, as regulations can change.
For homeowners in the Santa Clara CA and San Jose CA area considering an Accessory Dwelling Unit (ADU), the choice often comes down to prefabricated versus custom construction. A prefab ADU is built off-site in a factory and assembled on your property, offering a faster timeline and a fixed price. A custom ADU is built entirely on-site, allowing for unique architectural designs and specific material choices. Both options must comply with local zoning laws and building codes. To help you decide which investment is right for your property, we recommend reading our detailed internal article Prefab Vs. Custom ADUs: Santa Clara Cost Analysis, which breaks down the cost differences and long-term value for local homeowners.
