Why the Bay Area Chooses 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 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!
I had the pleasure of choosing Gadi construction for our bathroom renovation in Fremont. As a newer generation home owner, you could imagine , I know nothing about renovation and was dreading the process. Millie was extremely helpful in putting our mind at ease. She worked with us to to under our broader vision, see how they can be broken up into phases , what should be done together and what should be done another time so we wont exceed budget and be in construction hell.
Both me and my husband are busy professionals, and Millie made sure that our time was well spent on this project. She managed the setup for design, procurement, permits, inspection timeline and a project plan within our set budget.
She was a pleasure to work with !

We are super happy with our experience working with Nadav and GADI Construction. We had water intrusion come from multiple areas, and our previous contractors left us in a lurch with those defects. Nadav had to creatively figure out where and why those areas were causing water to enter (we learned there were multiple reasons!) and how to prevent it and seal the interior. He had to creatively figure out how to solve it, and it all worked out great! He and his team always communicated with us throughout the project, and they exceeded our expectations. Highly recommend them!
I engaged GADI Constructions Inc to restore my unit in a high rise in San Jose. Right from the beginning Millie, Project Manager, was very professional and when entrusted with the job completed the repair and restoration work smoothly and in time with perfection with time to time progress reporting on phone and through video.
We recently engaged Gadi Construction for a home renovation project, and the experience exceeded our expectations.

The quality of the final output was impressive, reflecting meticulous attention to detail. Millie, our dedicated project manager, along with her team including Mike, fostered a reassuring and collaborative environment throughout the process, ensuring clear communication and minimal disruption. We highly recommend Gadi Construction for any renovation endeavors; their professionalism and commitment to client satisfaction are commendable.

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.
