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 cost comparison between building a new house and adding an addition depends heavily on your specific circumstances. Generally, a well-planned addition can be more cost-effective per square foot than a new build, as you are leveraging existing infrastructure like the foundation, utilities, and one or more walls. However, additions often involve complex integration with the old structure, potentially uncovering unforeseen issues that increase costs. A new home offers complete design freedom and modern efficiency from the ground up but comes with higher land, permitting, and total construction expenses. A key factor is your current property's condition and value; if major foundational or system upgrades are needed, a new build might offer better long-term value. Always obtain detailed estimates from qualified contractors for both options.
The 30% rule in remodeling is a widely cited budgeting guideline suggesting that homeowners should not spend more than 30% of their home's current market value on a major renovation project. This rule helps maintain financial prudence and protects against over-improving a property relative to its neighborhood, which can make it difficult to recoup the investment upon sale. For example, on a $500,000 home, the recommended maximum remodel budget would be $150,000. It serves as a crucial initial checkpoint, though actual budgets must also factor in specific project scope, local construction costs, and personal financial health. Professional contractors and real estate advisors often reference this rule to ensure renovations align with long-term value.
The cost to add an addition in the Bay Area is significantly higher than national averages due to high labor costs, permit fees, and material expenses. For a basic room addition, you can expect a starting range of $300 to $450 per square foot. A more complex, high-end addition often ranges from $500 to $700+ per square foot. Therefore, a 500-square-foot addition could realistically cost between $150,000 and $350,000 or more. Key cost factors include the project's complexity, design finishes, site accessibility, and local permit requirements in cities like San Francisco or San Jose. It is crucial to obtain multiple detailed quotes from licensed contractors and budget for a 10-20% contingency for unforeseen issues.
The most expensive part of a home addition is typically the structural work, which includes foundation, framing, and roofing. These elements form the critical skeleton of the new space and require significant labor, materials, and engineering. Foundation work, especially if it involves excavation and pouring a new concrete slab or footings, is a major cost driver. Following closely are expenses for tying the new structure into the existing home's systems—like electrical, plumbing, and HVAC—which often involves complex modifications. High-end interior finishes (e.g., custom cabinetry, flooring) also represent substantial costs, but the core structural and systems integration usually commands the largest portion of the budget due to its essential, labor-intensive nature.
