Featured Reviews for ADU Contractors in Vallejo

Joseph Farrell Architecture
ADU Contractors in Vallejo
Average rating: 5 out of 5 starsFebruary 6, 2014
“Joe was exactly what we needed for our home remodel/addition project. We came in with lots of ideas but couldn't figure out how to pull it together and make it work. Joe was a great listener and quick to pick up on our style and needs, and in no time he was bringing solutions that we would never have come up with. In addition to being a real pro, Joe is very personable and a pleasure to work with. Highly recommended.”

Koch Architects
ADU Contractors in Vallejo
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.”

Smith and Son Construction
ADU Contractors in Vallejo
Average rating: 5 out of 5 starsDecember 26, 2022
“I have several reasons for highly recommending Smith & Son Inc. Our project was the installation of a composite deck over a worn out cement patio. Out of the three quotes we received, Lance Smith not only provided us with a detailed quote very quickly, he was the only individual we met with who followed up with us by telephone to discuss his quote. This discussion led to further clarity regarding our project and savings on the overall cost, putting us within our budget. Lance recommended a particular decking material which we are extremely pleased with. Knowing we were eager to start, Lance found a way to begin our project much sooner than expected. His three man crew was led by a seasoned and experienced foreman who not only guided his team, but also checked in with us frequently to make sure we were satisfied. Noe took great pride in his work and was very eager to please. They kept the work area tidy and safely stowed their equipment at the end of their workday. We are very happy with the finished project which exceeded our expectations. We would not hesitate to use Smith & Son again and would highly recommend them to friends and family.”
Sonoma Hill Builders, Inc.

Average rating: 5 out of 5 starsOctober 28, 2020
“We had the pleasure of working with Tom Ahearn as our project manager on our complete home renovation. Tommy is a consummate professional. Great ideas and designs are just the start- they have to be executed in the field. Forethought, preparation, meticulous attention to detail and great communication left us with a finished project which exceeded all of our expectations!!”
Keystone Home Improvements Inc
ADU Contractors in Vallejo
Average rating: 5 out of 5 starsJune 15, 2020
“Manny and his crew are on time, honorable, efficient and extremely neat. The Keystone builders installed our new kitchen, doors, windows and even rain gutters plus repaired tiled flooring with minimal disruption and lots of care. The work was so meticulous I was able to delay the interior painting for another year and instead their awesome team painted the exterior of the house in half the time we planned. I look forward to working with them again!”

“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.”
John Lum Architecture, Inc. AIA
ADU Contractors in Vallejo
Average rating: 5 out of 5 starsApril 3, 2011
“We used John Lum Architecture for the complete remodel of ~1000 sq ft in San Francisco. John and team were fantastic to work with. Very creative yet good at listening to our thoughts and integrating our ideas. They understand how to both design a gorgeous contemporary space while still keeping it comfortable and livable. We depended on them with a lot of design detail recommendations such as fixtures, paint, tiles and they always had great suggestions that made the process much simpler and easy to manage. They are very professional, extremely responsive and timely. There were no surprises during the entire process including on deadlines and budgets. I would strongly recommend them.”
QPS Inc.
ADU Contractors in Vallejo
Average rating: 5 out of 5 starsJuly 7, 2023
“Our company has worked with QPS for several years. We have done business with more than 140 other general contractors and other construction companies, both locally and throughout the state of California. Without question, we find QPS to be one of the top three general contractors that we have ever worked with. They are attentive, dependable and a pleasure to work with. They always do what they say they’re going to do but even more than that they under promise and over deliver every single time on every single project. Their prices are more than fair and they never overcharge….. it’s run like a family business is supposed to be operated. There are never excuses. QPS has a significant staff of qualified professionals. They never take on more work than they can handle or work that they are not qualified for. To be honest, we are always looking for projects to do so that we can partner our clients with them. We , ourselves are an interior design and interior architectural firm, who represent quality workmanship as you will see on our website, www.warrensheetsdesign.com. When asked to give recommendation I the president of Warren Sheets Design, jumped at the opportunity to give my two cents about QPS. But since I have been asked, I’m giving more than two. Cents to whoever asks! I am all in to recommend QPS to anyone who is looking for a general contractor to do a quality job for them that is small or large. QPS is an extremely credible firm. Warren Sheets.”

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 Vallejo. 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 Vallejo: 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.
