Featured Reviews for ADU Contractors in San Mateo

Nordin Builders, Inc.
ADU Contractors in San Mateo
Average rating: 5 out of 5 starsMay 25, 2016
“Nordin Builders did an extensive remodel for us. The existing structure came down, but we kept the foundation and expanded the footprint (2000 sq ft became 3000 sq ft). One of Dan Nordin's greatest attributes is professionalism, providing clear and reliable communication throughout the project. The workmanship was excellent and our timeline was adhered to, finishing the WHOLE house remodel in 11 months.”
Golden View Renovation
ADU Contractors in San Mateo
Average rating: 5 out of 5 starsMay 15, 2021
“Hi :) my name is Annabelle and we are from Sunnyvale California, I just finished a new renovation, and I would like to share with you guys my wonderful experience, we started the process with a lot of fears because of previous experience that we had with another contractor two years ago, from the first meeting with Asi, me and my husband felt the honesty and integrity right away, we describe to her what we would like to achieve in our kitchen remodeling project and together with ideas that came from her designer we decided on the final layout, We needed a new kitchen renovation for our home ASAP, we are all working from home, my husband and I and our older daughter, and the kitchen became much more important, it was very surprising but we succeeded to pass all the inspections on time, The communication part was great, personally I preferred to communicate with Asi directly but they are working with a personal online portal that some people will find useful, we needed a few times that Asi will come to us to discuss on a few changes and we always felt comfortable to share with her our concerns and ideas, and eventually we are very satisfied from the end result!”

“I found GreenStar Construction through word of mouth. I was impressed by the designs my colleague showed me with such a substantial budget on their home, so my wife and I decided to go with them. We were re-designing our kitchen. We changed countertops, sinks, backsplash and cabinets. The owner gave us phenomenal options to choose from within our budget. Jay has an eye for design which my wife really appreciated. He always answered our calls, answered all of our questions, and went up and beyond to make sure we stayed within our budget and were satisfied. Thanks Jay, my wife loves her new kitchen.”
Mayer's Construction and Remodeling
ADU Contractors in San Mateo
Average rating: 5 out of 5 starsDecember 4, 2022
“Great experience, high value, very reliable and best crew we ever worked with. Mayer’s construction did a home remodeling for us during the last 6 months. It has been a big home remodel for us that took design and build as well. After months spending finding the right company for us, we have choose to work with Mike & Nathan Mayer from Mayer’s construction. A week after finalizing contract we started working with Su & Luis both company’s architect and engineer. We worked on the new plans we agreed and wanted at first and started to have architect drawings ready, when we got into engineering process, both Mayer’s construction and us didn’t know we were suppose to redone so much of the existing footings and reinforce of additional walls as 20 years ago we did a 2nd story addition that was probably made poorly and unprofessional. They were extremely kind and helpful and kept the price as we agreed on and didn’t changed a thing. The plan process and measurements took about a month or so, and finally we were able to submit the plans to the city of San Jose. After getting the permits done and job card set ( overall 5 months of waiting / SJ is a pretty busy city) we got into work schedule and been ready to move out as the entire home going to be demolished. Mike was very organized both managing and scheduling the team, rough materials arrivals, and to us to be fully briefed with details and what we need and when. The process of work was great and on timeline , city did changed a lot during this time period with their inspection delays but it didn’t interrupt with our schedule or timeline due to great management ahead. We just finished our work and we absolutely in love with our new home! New flooring throughout, new kitchen, new bathrooms, complete open floor plan, new stair case, new rooms reconfigured, new paint, new texture, new windows and sliding doors throughout, all new plumbing and electrical. A brand new and beautiful home we got thanks to Mayer’s construction and the team, Mike, Nathan, Raul, Jose and many more who had a added value and did this work absolute best.”

Podesta Construction
ADU Contractors in San Mateo
Average rating: 5 out of 5 starsMay 20, 2012
“After receiving bids from and interviewing several contractors, we selected Podesta to do a top to bottom remodel of a Queen Anne house built in 1900. We had seen their work, appreciated their attention to detail, and knew they could handle a big job. We were not disappointed. Though the job took 3 months longer than first anticipated, we had made sensible and needed changes to the plans all during construction. Communication, both with us and with the architect, was very good throughout the construction. The site was kept very clean and any issues raised by neighbors during the construction were dealt with quickly and respectfully. After we moved back to the remodeled house, Podesta continued to correct problems and at the year anniversary of job completion, they met with us and corrected any remaining issues.”
Studio S Squared Architecture, Inc.
ADU Contractors in San Mateo
Average rating: 5 out of 5 starsOctober 4, 2012
“Eugene Sakai stood out far above the pack of the 5 Architectural firms that we investigated to do our total house construction. He was simply the best to deal with, very professional, on time, and took a personal interest in the project, and within budget. We moved in 2 years ago and still love him and the contractor, C.W. Wright in San Carlos. We are pleased to show the house through Eugene Sakai at any time.”

ON Design & Remodeling
ADU Contractors in San Mateo
Average rating: 5 out of 5 starsDecember 6, 2021
“After getting several estimates from different companies, I was fortunate to find ON Design & Remodeling. I had no idea what I wanted to do but ON Design & Remodeling came in, took a look at my kitchen, created a 3D Design that was mind-boggling to say the least. The reality of it is, they came in, completely demo’d my boring, old kitchen and gave me the kitchen of my dreams! And the hood itself is just a work of art. They exceeded my expectations at every turn. Literally impeccable workmanship! My kitchen turned out so amazing, we begin demo on my master-bath, master bedroom & closets in 10 days. I can only imagine what they will do there!”
Tycon Builders, Inc.

Average rating: 5 out of 5 starsDecember 23, 2020
“I am an architect based in San Francisco and I’ve been working with Mr. James Reid from Tycon Builders for years. I cannot praise James enough for his attentiveness to details, openness to new ideas/materials/technology, and the care he puts in for every projects. When it comes to building my own house from ground up, I trust Tycon Builders and have enjoyed the journey of building. James is a master builder who is hands-on, honest, and knowledgeable. I recommend Tycon Builders to anyone who wants a worry-free home.”

An accessory dwelling unit (ADU) is a separate living space that can be added to your property. It functions as an additional dwelling on the same land where your main home is located. ADUs have their own amenities and entrance, providing a self-contained living area. Unlike a traditional home, an ADU cannot be sold separately and is considered part of the same property.

ADUs are subject to specific zoning regulations and building codes in San Mateo. These regulations determine where and how an ADU can be constructed, ensuring compliance with local laws and requirements. It’s important to consult with local authorities or a professional contractor who is familiar with ADU regulations in your area to understand the specific legal differences and ensure your ADU meets all necessary criteria.

Consider these options for cost-effective ADU:
  1. Prefabricated ADUs: Affordable and easy to assemble, they’re a practical choice. Many prefab ADUs cost under $100,000.
  2. Traditional Construction: Work with an ADU contractor to find budget-friendly options and make smart choices.
Tips for cost-effective ADU construction:
  1. Define your needs: Determine the purpose of your ADU, whether it’s for family, rental income, or a home office.
  2. Consult a contractor in San Mateo: Their expertise can help with cost-effective materials, designs, and planning.
  3. Prefabricated components: Consider using prefabricated elements like cabinets or bathroom fixtures to save time and money.
  4. Explore financing options: Look for ADU-specific loans or programs to help cover costs.
Ensure compliance with local regulations and seek professional advice. A knowledgeable contractor can make the process smoother and cost-effective.
