Why the Bay Area Chooses Gadi Construction
Beautiful job updating the kitchen and shower. Our project manager, Eden was responsive and quickly moved the project along, completing everything in three weeks .
GADI did a great job updating our kitchen and shower.
Our project manager Eden was highly responsive, quickly understood exactly what we needed, and kept everything moving efficiently. The entire project was completed in just 3 weeks. Updating the kitchen included installing a new counter, a new sink, and a built-in dishwasher, and everything is beautiful and working well. They also painted the cabinet doors, greatly improving the look of the kitchen. For the bathroom, they removed a built-in bench, making the shower much more spacious, and beautifully replaced with new tiles, including the floor.
We just completed a full primary bathroom remodel with Gadi constructions and we could not be happier with the result. The quality of the work was excellent, the project was well managed, and the finished bathroom turned out beautifully and almost exactly to the vision I had in mind.
I especially want to recognize Millie, our program manager, who was exceptional from start to finish. Her enthusiasm for her work is infectious, but what impressed me most was how personally invested she became in getting every detail right. She approached the project as though she were working on her own bathroom, not a client’s. She was constantly thinking ahead, finding creative solutions, making things work when challenges came up, and never settling for “good enough.”
I traveled quite a bit during the remodel, and knowing Millie was overseeing everything gave me tremendous peace of mind. She kept the project moving, handled issues without creating unnecessary stress for me, and always made me feel that the details were in very capable hands.
Remodeling can be disruptive and stressful, but having someone who genuinely cares about the outcome makes all the difference. Millie went above and beyond in every sense, and the entire team delivered a bathroom we absolutely love. I would highly recommend them.

Gadi Construction did an outstanding job upgrading our lower bedroom and powder room- they completed a patio project for me that I am extremely happy with . I recommend Gadi Construction for their professionalism and also their customer care experience – definitely would recommend them and use them again for any future projects.
Gadi construction handled the remodel of my 2 bathrooms: the main and secondary. My project manager Eden was the reason I chose them, she was responsive and listened to what I needed. She guided me through the process and helped me choose the right materials. They were not the lowest quote but I felt I was going to get my project done on a timely schedule and completed to my liking. And we are thrilled on how they came out! Thank you Eden!

Worked very closely with Millie and team on a remodel of our 2000 sq feet property in Milpitas and it was a delight to work with Millie and the entire team. Millie took the entire burden off of our shoulders and had her team do some amazing work and a very tight schedule. The work the team has pulled off is amazing and we are extremely happy with the work and looking forward to moving back in.

The cost to build a 1200 sq ft ADU in California varies significantly depending on the location, materials, and design complexity. In the Santa Clara CA and San Jose CA area, you can generally expect a price range of $250 to $400 per square foot for a custom build. This means a 1200 sq ft unit could total between $300,000 and $480,000. However, these figures are for new construction and do not include permit fees, utility connection costs, or site preparation. For a more accurate comparison of building methods, we recommend reviewing our internal article titled 'Prefab Vs. Custom ADUs: Santa Clara Cost Analysis' Prefab Vs. Custom ADUs: Santa Clara Cost Analysis to see how different approaches affect your budget. Always consult with a local general contractor like Gadi Construction for a site-specific estimate.
The cheapest option for an Accessory Dwelling Unit (ADU) is typically a prefabricated or modular unit, as it minimizes on-site labor and construction delays. For homeowners in the Santa Clara CA and San Jose CA area, a junior ADU (JADU) is often the most budget-friendly choice because it can be created by converting existing space, such as a bedroom or garage, without requiring new foundation work. This approach significantly reduces permit and material costs. For a deeper look at maximizing value during a garage conversion, we recommend reading our internal article titled 'Converting Your Santa Clara Garage Without Losing Value: The Ultimate 2026 Guide' at Converting Your Santa Clara Garage Without Losing Value: The Ultimate 2026 Guide. Always consult with a local professional like Gadi Construction to ensure your project meets city codes while staying within your budget.
When building an Accessory Dwelling Unit, common mistakes include underestimating the total budget, as many homeowners forget to account for utility connection fees, impact fees, and design costs. Another frequent error is failing to check local zoning laws and setback requirements, which can lead to costly redesigns. Poor planning for the site's drainage and grading often results in water damage issues later. Additionally, many people choose the wrong contractor without verifying their experience with ADU projects specifically. To avoid these pitfalls, we recommend reading our detailed guide, Santa Clara County ADU Planning Permission: The Complete 2026 Guide to Permits, Costs, and Regulations, which covers all the necessary permits and regulations for Santa Clara County. Proper upfront planning and hiring experienced professionals are key to a successful build.
For homeowners in the Santa Clara and San Jose area, selecting the right ADU company is a critical step. You should prioritize firms with a proven track record in local permitting and construction, as city-specific regulations vary significantly. A reliable company will offer transparent pricing and a clear timeline. For a detailed breakdown of financial considerations, we recommend reviewing our internal article titled Prefab Vs. Custom ADUs: Santa Clara Cost Analysis. This analysis compares the costs of prefabricated units versus custom builds, helping you make an informed decision. Gadi Construction advises that you always verify a company's license, insurance, and past project portfolio to ensure they meet industry standards for quality and safety.
