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 !

Nadav and team did a great job retailing our bathrooms
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. Their team demonstrated exceptional flexibility, efficiency, and accommodation, adapting seamlessly to our evolving needs while maintaining a high standard of workmanship.

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 $40,000 grant you are referring to is part of the California Department of Housing and Community Development's ADU Grant Program. This initiative provides up to $40,000 in pre-development and non-recurring costs for homeowners building an Accessory Dwelling Unit (ADU). Eligible expenses include architectural designs, permits, site prep, and utility connections. The grant is available to owner-occupied single-family homeowners with a low or moderate income. In the Santa Clara and San Jose area, this funding can significantly offset initial costs. For professional guidance on navigating the application process and design requirements, Gadi Construction can help ensure your project meets local zoning and building codes.
The cost to build a 1200 sq ft ADU in California varies significantly based on location, design, and materials. In the Santa Clara and San Jose area, a standard detached ADU typically ranges from $250 to $400 per square foot. This means a 1200 sq ft unit could cost between $300,000 and $480,000. Factors influencing the price include site preparation, foundation type, utility connections, and interior finishes. Permits and impact fees in this region also add to the total. For a more accurate estimate, it is wise to consult with a local contractor like Gadi Construction, who can provide a detailed breakdown based on your specific lot and design preferences. Remember to budget for unexpected costs and always get multiple quotes.
As of 2026, California has continued to streamline Accessory Dwelling Unit (ADU) regulations to address the housing crisis. Key updates include reduced minimum lot size requirements, allowing ADUs on most single-family and multifamily properties without additional parking if the property is within a half-mile of public transit. Local jurisdictions can no longer impose owner-occupancy requirements for ADUs built after 2025. Additionally, the maximum allowable size for a junior ADU has increased, and impact fees are now capped or waived for ADUs under 750 square feet. For specific implementation details in Santa Clara and San Jose, property owners should review local zoning ordinances, as some cities may have additional standards. Gadi Construction recommends consulting with a local permit specialist to ensure full compliance with these evolving state laws.
Common mistakes when building an Accessory Dwelling Unit often stem from poor planning and underestimating costs. Many homeowners fail to secure proper permits or ignore local zoning laws, which can lead to costly delays. Another frequent error is choosing a design that does not maximize the available lot space, resulting in a cramped or non-functional layout. Budgeting too tightly without a contingency fund for unexpected issues like foundation problems or utility upgrades is also common. Additionally, selecting inexperienced contractors can compromise quality. To avoid these pitfalls, work with a trusted team like Gadi Construction to ensure your ADU meets all local codes and fits your long-term needs.
For homeowners in Redwood City, the planning process for a home addition involves several key steps to ensure compliance with local zoning codes and building regulations. First, you must verify your property's zoning designation, which dictates allowable lot coverage, setbacks, and height limits. A site survey and preliminary design are essential to assess feasibility. After developing plans, you submit them to the Redwood City Planning Division for review, which may include a public hearing if your project requires a variance or conditional use permit. To navigate these requirements efficiently, consider consulting our internal article titled 'Home Additions in Redwood City' at Home Additions in Redwood City for detailed guidance. Gadi Construction emphasizes the importance of early engagement with city planners to avoid costly revisions.
