Featured Reviews for ADU Contractors in Sunnyvale

Studio S Squared Architecture, Inc.
ADU Contractors in Sunnyvale
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.”
Green California Builders Inc.
ADU Contractors in Sunnyvale
Average rating: 5 out of 5 starsFebruary 20, 2019
“I can't say many wonderful things about Green California Builders. I wanted to built a new home and had no idea where to start in regards to design and construction permits. I heard about these guys because of my friend. I met EZ (the main project manager) after scheduling the appointment. He guided us through the entire process with ideas, advises and material selection. I liked his vision and we agree on the budget. Few days later the project started. After few months, we now have a wonderful new house. I'm so grateful to choose these guys and I recommended them 100%!!!”

“We planned a big project at first, and then the budget changed, so our plans had to change. California Construction was understanding, responsive, and stayed on schedule for the revised remodel. Excellent work!”
Golden View Renovation
ADU Contractors in Sunnyvale
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!”

“Had a great experience with Ofer and his crew. Came as scheduled, completed the job in 5 months. Everything looks great - The work went without a hitch so it ended faster than I imagined it would be too.

“A few things to say about Barcci Builders and Bar. I never asked, but Bar was ALWAYS updating mewith day to day updates during the remodel. It was great!

“5 stars to Decor Builders! Thank you so much to Guy and Decor Builders for remodeling my bathroom, I was thinking to do my bathroom for a very long time but I was really nervous about the process and didn’t know any contractor I could trust. Guy made it all look very easy as he explained me every step and was very detailed and patience with me, He helped me choose all the materials and also help me with his contractor discounted prices. I love my new bathroom, if you looking to renovate your home Decor Builders is the right choice.”
Roy's Builder's & Remodeling Inc.
ADU Contractors in Sunnyvale
Average rating: 5 out of 5 starsJuly 8, 2019
“I am extremely happy with the service and outcome of my kitchen remodel that I received from Roy. I decided to remodel it to have a more modern look, such as marble counters. Roy was very helpful and provided excellent customer service. He listened to what I wanted in remodeling my kitchen and gave me alternative ideas as well to expand on other ways to improve my kitchen. He recommended me to replace my lights and fix my walls and knew the perfect products for it.The price was also reasonable-- I was searching other companies and finding that their prices were too expensive. I had a budget and Roy was willing to work around that. It is not common to find other companies that are willing to give you what you need for a reasonable price. The work I received was worth what I spent and I highly recommend Roy to anyone who is looking for a kitchen remodel for quality work! I am very satisfied and I am looking forward to remodeling other aspects of my home with Roy.”

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 Sunnyvale. 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 Sunnyvale: 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.
