Featured Reviews for ADU Contractors in Napa County

ODS Architecture
ADU Contractors in Napa County
Average rating: 5 out of 5 starsAugust 25, 2012
“The staff at Ohashi Design Studio helped me design my kitchen/living space. I wanted to open up our galley kitchen to be able to see our incredible view from the kitchen. They came up with a design I never imagined could work so well. Rather than just remove a wall, they moved the kitchen, changed it to a more functional shape and not only opened up the view, but made the living space feel like we were outside. I have been especially impressed with their level of service. They listened to my dreams and goals and turned it into a reality beyond what I'd hoped for. They were available anytime I needed guidance during construction and made sure the project was built down to the finest details. They helped me find a contractor and oversaw the bidding process. They helped pick out all the materials and finishes, even the paint color. I can't say enough about their level of expertise and professionalism. I worked with Dave and Alan.”

“Alex is a skilled craftsman with an eye for design . He approached our project with enthusiasm and we ended up with something better than we originally hoped for. We appreciated his willingness to communicate on what was needed from us and made the process as painless as possible. I definitely recommend Slarve Construction.”

New Key Construction
ADU Contractors in Napa County
Average rating: 5 out of 5 starsJuly 25, 2019
“NewKey has been by far the best GC in the Bay area I have ever worked with. From the start of planning, to the coordination with their subs and team members for installs, they have been very detail oriented. As challenges arise which they always do, they actually pick up the phone when you call and work on resolutions within hours not days or weeks! I am thrilled with the progress and would recommend them to anyone. Now that I have a great remodeled kitchen - I look forward to them doing my master bath!”
IGreen Builders Inc.
ADU Contractors in Napa County
Average rating: 5 out of 5 starsApril 27, 2022
“We hired IGreen builders to remodel our master bathroom. The company was the fourth we interviewed with and we were deeply impressed by Liron Knot wide experience, their design ideas and their reasonable price, so we offered them the job on the spot. We were so glad we did that! This was a wonderful team - Liron gave us lots of great ideas on the design. He was our project manager, and was very experienced and customer oriented. I often called him multiple times a day and he was always very patient to answer my questions and kept me updated on the daily schedule. The crew was very professional, courteous and highly skillful - we really love the great tile work. Tony and his folks did an excellent job. Now we enjoyed our beautiful bathroom everyday and we are so glad we hired this team. We love their work so much that we decided to remodel the two bathrooms upstairs as well with them, which are ongoing right now.”
SDG Architects
ADU Contractors in Napa County
Average rating: 5 out of 5 starsAugust 3, 2015
“Jeff Potts at SDG designed us an incredible, award winning guest house! What I particularly like about Jeff is his open and approachable style. We've worked with many architects over the years and many simply don't want to listen to the client. Jeff listens and then delivers a design beyond your expectations. I would highly recommend working with them.”
Golden Heights Remodeling
ADU Contractors in Napa County
Average rating: 5 out of 5 starsJuly 28, 2021
“Golden Heights remodeled our kitchen and we love it! The project required moving one interior wall, moving a door and windows and adding two windows. The house is stronger now with better shoring and support than before. We felt that Golden Heights was a one-stop shop with a network of designers, engineers, architects, electricians and of course, builders. Neryah was our project manager; he guided the process from start to finish. Neryah spent hours listening to our ideas and making sure that every detail was planned for ahead of time. He helped make design and lighting choices, shopped for tile with me, and designers from GH identified the perfect cabinet source for us. Once we were given a contracted price there were no increases or change orders except for what we wanted to add (removing crown molding and painting another room). Eran talked me into a pot filler over the stove (no extra charge for installation) and guess what...I use it almost every day. The construction crew that showed up each morning were courteous, friendly, hard working. Every day they cleaned up and made our house as livable as possible. Shout out to Ulysses and Memo! Golden Heights took care of foundation work, framing, stucco, texturing, painting, floor and cabinet installation, tiling, plumbing, electrical...all the things. Neryah is a perfectionist who insisted a few times that work be done the more difficult yet right way, even when we would have probably been satisfied otherwise. The amount of time the crew spent on the project was much less important to him than having it done the best way. Of course we had a couple of hiccups along the way, but never anything that caused us worry or conflict. Neryah is a problem solver for sure. We are typically DIY people (we have remodeled our three bathrooms, installed flooring, painted everything, husband used to build cabinets) but this project was too big for us. As fairly knowledgable folks, we can recommend Golden Heights as knowing their remodeling stuff.”
Koch Architects
ADU Contractors in Napa County
Average rating: 5 out of 5 starsJanuary 29, 2014
“I just completed a complete remodel of my San Francisco Edwardian flat and build out my basement. Joanne and her staff did a fantastic job. It started out as a kitchen bath remodel, but once the design process started expanded to include every room as we discussed how different spaces would be used and what I didn't like about the current space after living with it for 20yrs. Might as well do it right! Joanne's attention to detail, listening, and high ethical standards are unmatched. She would listen in the meetings and ask questions then come back with some ideas and sketches to get my reaction. She knew what I wanted without me even knowing it. She was also sensitive to the project budget which was important. I was able to complete the project within my budget. She was also key to working with the general contractor. She brought with her experience in projects of my scope / scale and working with different contractors and even her own remodel. This helped immensely. I look forward to the opportunity to work with Koch Architects again.”
CA Bear Construction
ADU Contractors in Napa County
Average rating: 5 out of 5 starsJuly 21, 2023
“Ca Bear is the best, for so many reasons. The first project we did with them was a complete kitchen remodel December 2020. We took down walls, opened up our entire layout and had the best experience ever. A few things that stuck out to us: The speed at which work was completed. So efficient, and that matters when you’re spending a lot of money. Everyday ended with a shop vac sweep and our home was left as clean as it could possibly be. The creative vision that Brenda had for us. I don’t have that lens so thank god for her! The communication that Brenda provided us each day, we always knew what was happening and if there were any changes. Her management was key. Our kitchen was completed 2.5 years ago now, and everyday we sit there and say, “we love our kitchen.” We just love it! After the kitchen we did a closet remodel, again, awesome. Salvador is an incredible wood worker and again, Brenda make the whole process so smooth. A year ago we did a basement and laundry room conversion into a bedroom and laundry/full bathroom. We couldn’t be happier. Everything is still looking amazing, the quality of work is superb. We are so happy. I take my referrals seriously, and I back CA Bear while heartedly. They’re good people, trustworthy and hard working. And to me that matters the most.”

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 Napa County. 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 Napa County: 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.
