Great guys to work with and still get them to do my home improvement
Leo and his team were great! They did high-quality work and communicated well during our bathroom remodel. They know how to do everything and we love the finished result. They are kind and respectful and do not cut corners!
I wish I could fully express how wonderful our experience with Generation Builders actually was. Luis was our main contact point, he was quick to answer any questions. Everything was addressed no hesitation. I highly recommend using Generation Builders.
Amazing Partner, very punctual, High Quality.
Generation Builders really came through for us - we decided to remodel our guest bathroom with just over 2 weeks before our guests arrived. David provided a prompt quote, got a team started the very next day, and oversaw every detail to make sure nothing got missed.
Leo and his crew did an attached ADU, and overhaul/refresh of our house (interior to exterior refresh- repaint, lighting, stucco, concrete work etc) which was a massive undertaking.
Generation Builder's was referred by our architect, and it was one of the best decisions. We interviewed 7 other contractors and we went with Leonardo and his team.
Jimmy and his team helped me renovate my house. It took a little time at the beginning to fine-tune our communication, but once we aligned, everything went smoothly.
We interviewed several construction companies for our bathroom remodel, and when we met David from Generation Builders USA, we knew we had found the right company.
Half our kitchen cabinets had to be ripped out because of a water leak. Pedro and Alex restored it and made it look just like new in 1-1/2 days. We highly recommend Generation Builders.
Generation builders is one of the best contractors we could have worked with... we did a home remodel in 2023 when our younger son was all of 1m old. We had to move out of the house for the duration.
I wanted to renovate my unfinished ground floor space in my outer sunset home to create a home office and additional living space. Generation Builders gave me a great quote and delivered excellent work.
The first thing that attracted us to Generation Builders was their name and company logo... what we discovered was a treasure of craftsmanship, knowledge, and professionalism.
I would like to thank Pedro who managed a demolition project for us. We had an old dilapidated ADU inherited from a previous homeowner and it needed to come down.
Generation Builders does good and timely work. We are very happy with the tile work and plumbing in our new bathroom. Their pricing is right on with a promise to deliver.
Just wanted to drop a quick note to express my gratitude towards Generation Builders. I hired them last year for my new house construction, and they've been nothing short of amazing.
I highly recommend this company as they did an excellent job remodeling my house.
I definitely recommend! Congratulations guys, I will see you in our next project! Thank for your great ideas.
Generation Builders came to my house today to replace a skylight. They were on time and did a fantastic job. They were very efficient and did a very thorough job.
Leonardo is always very responsive and with great customer service, very organized and always ready to help, plus the quality and how beautiful the 3D design they create.
Very professional. Thank you very much, we are very happy with the service!
It was with some trepidation when we made the commitment to remodel our entire house. Have always heard the nightmare of stories of sporadic appearances by contractors, but Generation Builders proved us wrong.
Mr. Leonardo is an incredible person, he solved all the problems in my house, during the renovation everything was clean and isolated, I would recommend this company to everyone.
I highly recommend this construction company for their exceptional workmanship and attention to detail. Their team is professional, efficient, and dedicated to delivering high-quality results.

Local Expertise
Why Midtown, Palo Alto is one of the San Francisco Bay Area's top ADU markets
Midtown Palo Alto offers a more accessible entry point into the city's real estate market while maintaining excellent schools and walkability. The neighborhood's 1950s ranch homes are popular renovation targets — buyers purchase them specifically to update kitchens, open floor plans, and add square footage through room additions. Midtown's central location and strong rental demand also make it one of Palo Alto's most active markets for ADU construction.
Palo Alto homeowners are increasingly turning to ADU construction as a way to generate rental income, house family members, or create dedicated workspace. California's streamlined ADU laws have made the process more accessible than ever, and our team handles every step from site assessment to Certificate of Occupancy.
The Bay Area is experiencing an ADU boom, and for good reason. New state laws have eliminated many of the barriers that previously made ADU construction difficult. We stay current on every legislative update so your project moves forward without bureaucratic roadblocks.
California now allows homeowners to build both an ADU and a Junior ADU (JADU) on a single-family lot — no special use permit required in most Santa Clara County cities.
