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 in California typically refers to the CalHFA ADU Grant Program. This initiative provides forgivable loans of up to $40,000 to qualified homeowners to cover pre-development costs associated with constructing an Accessory Dwelling Unit (ADU) or Junior ADU (JADU) on their property. Eligible costs include impact fees, plan check and permit fees, soil tests, architectural designs, and energy reports. The loan is forgiven if the homeowner completes the ADU and occupies it as their primary residence for five years. This program aims to increase affordable housing stock by reducing the financial barriers to ADU construction. It is crucial to check current program guidelines, as funding availability and specific terms can change.
The cost comparison between building an ADU (Accessory Dwelling Unit) on-site and buying a prefabricated one 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 and may better integrate with an existing property's architecture, potentially increasing property value. Key cost factors include foundation work, utility connections, permits, and finish levels. For either option, obtaining accurate local quotes is essential, as regional material and labor costs vary widely. A prefab unit might have a lower base price, but total installed cost with site work can narrow the gap significantly.
The cost to build a 1000 sq ft Accessory Dwelling Unit (ADU) in California varies significantly based on location, design, and finishes. On average, you can expect a range from $200,000 to $400,000 or more. This includes expenses for design, permits, site work, foundation, construction, and utility connections. Key cost drivers are the complexity of the project, whether it's attached or detached, and the quality of materials. Prefabricated or "pre-fab" ADUs can sometimes offer cost savings. For a detailed breakdown of factors influencing ADU costs and current market insights, we recommend reading our internal article Bay Area Kitchen, Bathroom, Home Remodeling, Additions & ADU | Gadi Construction. Always obtain multiple detailed quotes from licensed contractors.
The cost comparison between adding an addition to your main house versus building a separate Accessory Dwelling Unit (ADU) depends heavily on specific project conditions. Generally, a well-planned ADU can be more cost-effective per square foot because it often involves simpler systems and avoids the complexities of tying into an existing occupied structure. However, a basic bump-out addition might be cheaper if it requires no new foundation, plumbing, or separate utilities. Key factors include site access, utility connections, and local permit fees. For either option, obtaining multiple detailed quotes is essential, as hidden costs for foundations, utility upgrades, and finishes dramatically impact the final price.
The cost of ADU construction in Hayward varies significantly based on size, design, and site conditions. A basic, prefabricated junior ADU can start around $120,000, while a new, detached 800-square-foot unit typically ranges from $250,000 to $400,000 or more. Key cost factors include foundation work, utility connections, permits, and interior finishes. It's crucial to work with a licensed contractor who understands Hayward's specific ADU ordinances and can navigate the permit process efficiently. For a detailed breakdown of costs and the value an ADU can add to your property, we explore this extensively in our internal article Bay Area Kitchen, Bathroom, Home Remodeling, Additions & ADU | Gadi Construction. Always obtain multiple detailed bids and ensure your budget includes a contingency for unforeseen expenses.
The Hayward ADU checklist is a crucial tool for navigating accessory dwelling unit projects in Hayward, California. It outlines the key steps and requirements for compliance with local zoning and building codes. Essential items typically include verifying property eligibility, such as lot size and existing structures, and ensuring proposed designs meet specific setback, height, and parking regulations. The checklist also covers necessary documentation, like site plans and architectural drawings, and guides applicants through the permit application process with the City of Hayward's Community Development Department. Following this checklist meticulously helps streamline approvals, avoid costly delays, and ensure the ADU is built to current safety and construction standards.
