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 30% rule for renovations is a common budgeting guideline suggesting that you should not spend more than 30% of your home's current market value on a major renovation project. This rule helps homeowners avoid overcapitalizing, which is when the cost of improvements exceeds the value they add to the property, making it difficult to recoup the investment upon sale. For example, if your home is worth $500,000, your renovation budget should ideally stay under $150,000. This is a general benchmark; the appropriate percentage can vary based on your neighborhood, the scope of work, and your long-term plans. Always consult with a professional appraiser or contractor to assess the potential return on investment for your specific project before committing funds.
The cost comparison between building new and doing an addition depends heavily on specific circumstances. Generally, a well-planned addition can be cheaper than new construction because it utilizes existing foundations, utilities, and structure, avoiding costs for an entirely new lot and core systems. However, additions often involve complex integration with the old building, potentially leading to unforeseen expenses like upgrading outdated electrical or plumbing to meet current code, which can escalate the budget. New construction typically offers more predictable pricing and avoids the constraints of an existing footprint. For an accurate assessment, obtain detailed quotes for both scenarios, factoring in your property value, long-term goals, and the scope of work. Consulting with a professional contractor is essential.
The cost of a 20x20 room addition in California varies widely based on location, materials, and complexity, but a general range is between $80,000 and $200,000 or more. In high-cost coastal areas like San Francisco or Los Angeles, prices often start at $100,000 for a basic addition and can exceed $250,000 for high-end finishes. Key cost factors include site preparation, foundation work, roofing, electrical, plumbing, and HVAC systems. Permits and design fees in California also add significantly to the budget. It is crucial to obtain multiple detailed quotes from licensed contractors, as unforeseen issues like soil conditions or strict local building codes can substantially increase the final project cost.
The cost to add an addition in the Bay Area varies significantly based on size, complexity, and finishes. For a basic room addition, you can expect a starting range of $300 to $450 per square foot. A more complex, high-end addition with kitchens or bathrooms can easily reach $600 to $800+ per square foot. Key cost drivers include architectural plans, permit fees (which are substantial in Bay Area cities), site conditions, material choices, and current labor rates. It is crucial to budget for unforeseen issues common in older Bay Area homes. For a detailed breakdown of costs and considerations for additions and ADUs, we recommend our internal article Bay Area Kitchen, Bathroom, Home Remodeling, Additions & ADU | Gadi Construction. Always obtain multiple detailed quotes from licensed contractors.
For homeowners in Sunnyvale considering cost-effective home additions, strategic planning is key. Focus on projects that maximize existing space, like converting an attic or garage, which often requires less structural work than a new build. Using cost-effective but durable materials and a clear, fixed-price contract with your contractor helps control budgets. It's crucial to work with a licensed professional who understands local Sunnyvale building codes and permit requirements to avoid costly delays or revisions. For a comprehensive look at planning a value-driven addition in the Bay Area, including ADUs and other expansions, we recommend our detailed resource: Bay Area Kitchen, Bathroom, Home Remodeling, Additions & ADU | Gadi Construction.
