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 to build an Accessory Dwelling Unit (ADU) in Oakland varies significantly based on size, design, site conditions, and finishes. For a basic, detached 500-600 sq ft unit, you can expect a starting range of $250,000 to $350,000. More complex designs, high-end finishes, or challenging sites can push costs to $400,000 or higher. Key cost drivers include foundation work, utility connections, permit fees specific to Oakland, and current material and labor rates. It is crucial to budget for soft costs like architectural plans, permits, and impact fees. For a detailed breakdown of ADU costs and the value they bring, see our internal article Bay Area Kitchen, Bathroom, Home Remodeling, Additions & ADU | Gadi Construction. Professional consultation is essential for an accurate estimate tailored to your property.
The $40,000 grant in California typically refers to the CalHFA ADU Grant Program. This initiative, administered by the California Housing Finance Agency, provides forgivable loans of up to $40,000 to qualified homeowners to cover pre-development costs associated with building an Accessory Dwelling Unit (ADU) or Junior ADU (JADU). Eligible costs include impact fees, planning and design, soil tests, and permit applications. The loan is forgiven if the homeowner completes the ADU and rents it to a low-income household for at least five years. This program aims to increase the state's affordable housing stock by incentivizing property owners to create new rental units. It is a key tool in addressing California's housing crisis, though specific program details and availability can change, so checking the official CalHFA website for current guidelines is essential.
The cost comparison between building an Accessory Dwelling Unit (ADU) on-site versus buying a prefabricated model depends heavily on project specifics. Generally, prefab ADUs can be cheaper and faster due to controlled factory construction, which reduces labor time and material waste. However, site-built ADUs offer greater customization to match existing structures and navigate unique lot constraints, though they often incur higher labor costs and longer timelines. Key factors include local permit fees, foundation requirements, utility connections, and finish selections. For a definitive answer, obtain detailed quotes for both options in your area, as regional material and labor costs vary significantly.
The maximum size of an Accessory Dwelling Unit (ADU) in Oakland is primarily governed by California state law, which sets the baseline. For a detached, new construction ADU on a single-family lot, the maximum size is 1,200 square feet. For ADUs attached to the primary residence or built within existing space (like a garage conversion), the limit is 50% of the existing primary dwelling's floor area, though it cannot exceed 1,200 sq ft. Oakland's local code may have additional provisions based on lot size and zoning, so consulting the city's Planning and Building Department is essential for a specific project to ensure compliance with all setback, height, and design standards.
