Featured Reviews for ADU Contractors in Portola Valley

Rolm Design Studio
ADU Contractors in Portola Valley
Average rating: 5 out of 5 starsMay 22, 2017
“Mehran is extremely knowledgeable from a design, cost, and feasibility perspective. I worked with Mehran on a complete teardown/rebuild of an existing single family home to a 90% new home. The main factors I needed addressed were cost concerns while keeping the best design and functionality for resale. Mehran gave insightful opinion and pointed out issues I had not and was not able to spot due to my relative unfamiliarity. His years of experience allows him insight on issues from both a building and cost perspective that would otherwise go unnoticed. Highly recommended.”
Mayer's Construction and Remodeling
ADU Contractors in Portola Valley
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.”
Level Up Home Remodeling Inc
ADU Contractors in Portola Valley
Average rating: 5 out of 5 starsApril 19, 2017
“Our recent home project included the complete remodeling of the kitchen, 3 bathrooms and wet bar. My husband and I decided on Level up home remodeling following our due diligence process (having interviewed multiple contractor candidates) given the prior reviews, competitive proposal, and positive impressions following our discussions with Issac. Issac estimated 3 months to complete the project beginning in August 2016, and although there were the unknown but expected bumps in the road along the way during the project, was able to complete the job on a timely basis. Both quality of workmanship and timely completion of the job was important to us, and Issac and his team delivered on both counts. Those working on our project were hard working competent individuals, punctual, courteous and easy to engage in conversation. Issac was at our site on a daily basis both overseeing the project and hands on with regards to any task. He and his team provided professional, thoughtful and viable options and resolutions to each situation/issue as they arose. We have used other contractors in the past, but Level up home remodeling outperformed all the predecessors. We are pleased with the results and would not hesitate in bringing back Issac team for other construction projects going forward.”

NuHome Remodeling
ADU Contractors in Portola Valley
Average rating: 5 out of 5 starsNovember 23, 2020
“Tony and his team did an excellent job . They expanded my master bedroom including the bathroom and a walk in closet. I am not the easiest customer. I had so many questions, and Tony was patient with me every step of the way. They were very thorough and competitive. They were constantly updating me and going over the process . The entire experience was great!! Always on time with a great attitude. I want to say that I worked with a few general contractors over the years and it is difficult to find a good one that actually keeps you updated. If you are looking for a good contractor, look no further! I am very satisfied!!! Thank you Tony and Nuhome! -Clement”

“Lecut Construction is one of the best remodeling companies out there! We contacted them looking for help with an our kitchen remodeling project. Their friendly receptionist replied promptly and we had a project manager,Michael and guy , at our house in just few days. The project managers Michael and guys was extremely attentive to all our concerns and questions and took full control of all the necessary paperwork and scheduling. Prior to contracting with Lecut we have postponed our project multiple times in fear of the headache and time-consumption we expected to have, however, Michael and guy made the project effortless for us. After the completion our kitchen looks incredible! Prior to committing to Lecut we have consulted with multiple companies, but none came near to the in-depth knowledge, caring customer service, and detailed quote and project plan that Lecut provided. We are looking forward to contacting LeCut for all of our future renovations and highly recommending.”
EBCON Corporation

Average rating: 5 out of 5 starsJuly 13, 2014
“Finding a contractor you trust and one that does great quality work seems harder than it should be. Fortunately we were recommended to Erik and Ebcon by a woman who was helping us think through some work we needed done on our home that included lighting, painting, plumbing and creating a new "man cave" in our basement. From our first meeting we were impressed. We have now been working with Ebcon on several projects for the past 2 years and are thoroughly pleased with the work his team has delivered. Erik and his team put a very personal touch and a high degree of care in their work which included weekly face to face meetings to review work and progress and discuss the inevitable changes or unexpected issues that pop up as work begins. Ebcon has repeatedly met and in some cases exceeded our needs and the high touch high communication has been great at identifying issues quickly and collaboratively resolving them. Since my wife and I lead busy lives, Erik has always found a way to pick times even super early in the morning to come by and have our regular updates and discussions. I highly recommend Erik if you are looking for a great team that does top notch work and keeps you very close to what is happening and strives to give you exactly what you want. They are super. Some of the work Erik did in our home is featured on his site today under "Whitaker"”

Clever Design & Remodeling
ADU Contractors in Portola Valley
Average rating: 5 out of 5 starsApril 10, 2020
“We hired Clever Design and Remodeling to remodel our kitchen in our condo. We had met with two other contracting companies and we were given a similar quote as Clever but to be honest, meeting with Gilli gave me a totally different level of confidence than meeting with the others. We replaced most of the carpeting in our home with European Oak wood flooring which is beautiful. We also had the kitchen cabinets refinished and a new stainless steel over the range microwave installed as well as coordinating new sink fixtures and all new cabinet hardware. Recessed lighting was installed in the living room, kitchen, and master bath with necessary patching and all ceilings painted. Roy was very knowledgeable of all aspects of the project -plumbing, electrical, carpentry- displaying true craftsmanship in his work. Gilli was great to work with, she is very detail oriented and he and his team always left our house and the common areas in the condo building extremely clean (cleaner than it was originally, honestly). The Clever Design and Remodeling team really went above and beyond in making sure we were comfortable and happy with the work. Strongly recommended!!!!”

“I was looking for a company to remodel my mom's property in alameda. I heard about this company from a friend and I decided to give it a shot . My mom is 75 years old and not able to communicate so I came to help her. Initially, we wanted to remodel our kitchen but decided to extend our kitchen and dinning room by breaking the wall that divided it. Maor the owner had a lot of layout options to choose from. He is very knowledgeable about design, and offered other possibilities. He also explain the different price between each option . We decided move forward with the build out and started the work on feb 14th. It took him 6 weeks to finish the project. My conclusion: He was almost every day supervise the different crews. Easy to communicate with. He is very pleasant person, he alway find a solution to any request we had. The crew was very professional and pass all inspection the first time . Every day they clean my house and moved their equipment on the side of the house . They didn't work on weekends for our request. He helped us choose all the fixtures from different supplier. Most of the guys speak English and very respectful to both my mom and I. The prices was fair for the quality of the job. The quality of his work is very high and the finish was super. Now we are thinking about doing the 2 bathroom and other area of the house. He will definitely be the contractor I choose . If anyone want to see picture feel free to email me and I will send him the pictures. Thank you very much for making this project a pleasant experience.”

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 Portola Valley. 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 Portola Valley: 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.
