Why the Bay Area Chooses Gadi Construction
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 explored a home addition for our growing family and these folks handled everything with a lot of thought. The builders explained the remodel plan clearly and made the space blend into the house naturally. It was a solid experience all around.
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. 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.

We worked with Nadav from Gadi Construction during the planning phase of our expansion project, and he was a fantastic advisor throughout the process. He helped us think through every detail — from design implications to quality considerations — and brought a thoughtful, thorough, and methodical approach to each discussion.
Nadav was always friendly, highly professional, and incredibly responsive. It consistently felt like he was acting as a truly independent advisor who cared deeply about building long-term relationships and making sure we would get the very best outcome for our project. His proposals were detailed, insightful, and clearly grounded in deep experience.
Although we ultimately moved forward with another contractor who came through a personal referral, that decision wasn’t a reflection on Nadav’s work or professionalism. Based on our experience, we’d be thrilled to work with him in the future and wholeheartedly recommend him to anyone looking for a trusted, high-quality construction partner.
I went with them for a kitchen makeover and it was worth every penny. The design team helped me see options I never thought about.
Their skilled builders were respectful of the house and kept everything tidy. It felt like a real partnership through the whole remodel.
The value added by the new layout is already noticeable. I still walk in and smile because the remodel turned out exactly right.
Taking on a whole house renovation sounded stressful but they took the edge off. They walked us through each stage of the project so we always knew what was happening. The result feels like a true custom home remodeling job.
The bathroom remodel completely changed how our space feels. Their team helped plan everything so the design made sense and looked great. The quality build is obvious in every corner. It’s nice to have a space that’s functional and adds value at the same time.
We worked with this business for a full residential remodel, and it was a great experience. The skilled builders brought the design to life exactly as we imagined. Every room feels intentional and high-quality. I’d happily recommend them to anyone looking for a thoughtful and professional remodel.

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.
