Customers credit Ray and his team with clear updates and practical design choices during ADU and remodeling projects. One says wider doorways and a walk-in shower made an attached ADU suitable for aging in place; another says Ray explained the added reinforcement needed for a garage conversion.

Customer Reviews

Jethro Patalinghug

Searching for ADU builders in Palo Alto felt intimidating at first. It’s a major investment. King David Home Builders made it manageable. We built an attached ADU for aging in place. Accessibility was critical. Ray suggested subtle adjustments like wider doorways and a walk in shower that didn’t look clinical. Those small details made a huge difference. The project stayed close to schedule, and when inspections were needed, everything passed smoothly. Now we feel prepared for the future without having to move homes.

Carmel Trela

Our experience with King David Home Builders started after researching ADU builders in San Jose for months. We wanted to convert our detached garage into a livable unit. The structure needed reinforcement, which we did not anticipate. Ray explained the engineering requirements clearly. It added work, but it made the structure safe and code compliant. The finished space is stunning. High ceilings, smart layout, and efficient use of every inch. It is now rented to a young professional, and the rental income covers a large portion of our mortgage.

Nicholas Delao

We interviewed three ADU builders in Palo Alto before choosing King David Home Builders. Ray stood out because he focused on practicality and long term value instead of flashy sales talk. Our goal was rental income. We needed the numbers to make sense. Ray helped us adjust the layout slightly to maximize square footage without increasing costs dramatically. That small design tweak ended up increasing our projected rental return. Construction was organized. The team worked full days and kept the site tidy. There were minor material delays with windows, but communication was constant. No guessing, no chasing updates. Now the ADU is rented, and the tenant signed a two year lease. It has already changed our financial outlook
