    The History of A+ Construction 30+ years of expertise in the construction field

    In 1935, in a small European village, Nicholas was born. He developed a passion for construction that he spent years perfecting. Nicholas later passed that knowledge on to his son Edgar. In 1997, Edgar began working in the construction field in Massachusetts. Edgar then passed on all he knew to his son, Roman.

    Roman’s humble beginnings in this family-owned business are why he is committed to providing great craftsmanship. He takes pride in the quality of work that the team at A+ Construction & Remodeling has provided for more than 30 years.

    What Our Customers Say About Us

    Over 1000+ satisfied clients, and here’s what they have to say about us

    Review Photo
    Harper Nelson

    Our experience of building an ADU with A+ was fantastic — from the initial design process to the construction itself. The crew was professional, and I loved watching each phase come together. When the ADU was finally complete it felt and looked like it has always been there. Even our neighbors have commented on how seamlessly it blends in with the main house, which was important to us. If you’re looking to build an ADU, we highly recommend A+ Construction.

    Aiden Carter

    My wife and I relocated from Portland to be closer to our daughter here in Sacramento. Instead of buying a new house, we decided to build an ADU on her property. After reviewing a couple of contractor bids, we chose A+ Construction, and we’re so glad we did. We’ve been now living in our new home for about 4 months now, and we really love it! 10/10!

    Jamal Brooks

    A+ Construction ADU Builders was a great choice for our backyard project. We toured several ADUs before deciding to hire A+. They have thought of everything. They handled all of the permits, change requests, etc. Together we created a beautiful home for our daughter. I would hire them again a hundred times over.

    Evelyn Gonzalez

    At the beginning off 2024 we became the proud owners of an A+ ADU. The process was better than we could have hoped for. Though we had never gone down this road before, A+ Construction made us look like we knew what we were doing. The process was transparent and there were no surprises. They stayed on budget and on time. We highly recommend A+ Construction ADU Builders!

    Javier Torres

    A+ team were a dream to work with. Everyone on the team including all of their subs were great, on time, communicative and professional. We have done quite a few home remodels over the years and we decided to hire A+ Construction to build an ADU on our property for our parents. Everything from initial design to completion met our expectations. They really listened to us and what we wanted. We would use A+ again and recommend anyone considering building an ADU to work with them.

    When I started looking for someone to build our ADU, it was tough to choose until I met with Oleg from A+ Construction. From the start he made me feel comfortable and sure I made the right choice. The work was excellent, I’d give them 10 out of 10! The workers were all skilled and easy going. After they finished our ADU, my in-laws decided to have them start on a project at their house too.

    Bill W.

    A+ Construction Pro helped us transform our old garage that was basically a glorified storage room, into something truly functional—a bright, open home office that fits our needs perfectly. The process went really smoothly. Our PM Serge kept us updated, and the crew was respectful of our property. Now, instead of staring at clutter, we have a beautiful new space. Couldn’t be happier with how it turned out thanks to A+!

    Lily King

    We’ve always wanted a guest house for family and friends to stay in when they visit, and A+ Construction ADU Builders helped us bring that dream to lifes. From the first consultation to the final walk-through, the team was easy to work with. What I appreciated most was how flexible they were with our design ideas. They took the time to understand what we wanted and made it happen. Now we have a charming guest house that fits perfectly in our yard, and we are happy to give A+ 10 out of 10!

    My husband and I decided to convert our garage with A+ Construction ADU Builders after we had to let go of our previous contractor. Despite the challenges of converting a small garage space, the results were absolutely outstanding! We are thrilled with the final look. 100% recommend!

    Lamar Evans

    I’d been dreaming about adding a tiny home to our property for years, and A+ Construction made it happen. The team worked with us to design something that was not only practical but also looked great in our backyard. It was a big project, but they handled it with ease. I didn’t have to stress about permits or construction delays—they took care of it all. We’re thrilled with how it turned out!

    Chloe Scott

    A+ Construction did an incredible job turning our old shed into a livable ADU. I have to admit, I wasn’t sure what to expect going into this, but the team walked us through everything step by step. Our manger Nick was always available to answer any questions we had, and the finished space looks amazing. It’s like having a whole new home right on our property! Thank you Nick and the A+ team!

    My wife and I were preparing for retirement and wanted to build a smaller ADU on our property to downsize. We chose A+ Construction, and we’re so glad we did. Now we have a beautiful 2-bedroom ADU that’s perfect for us in our retirement years. The team really delivered on their promises!

    Our 2-story ADU by A+ Construction & Remodeling is great! These team is total professionals, always ready to help. They not only had all the answers to our questions but also guided us through the details of plans and permits.

    Ava Lewis

    My daughter and I decided to build a tiny home in our backyard, but we had no idea where to start. After reaching out to a few contractors, we felt the most comfortable with A+. Their team was incredibly patient and explained everything from permits to design in simple terms. We now have a cozy tiny home, and it came out even better than we imagined. If you’re thinking about building an ADU, this is the company to go with.

    Kendrick Johnson

    We were looking to build an ADU to rent out and found A+ Construction ADU Builders. After comparing a few companies, we chose them because of the detailed quote and the price that included everything upfront. Oleg helped us design a layout that would work for tenants, and the finished unit is even better than we hoped for. The quality of the build is outstanding, and we’ve already had several people inquire about renting it. Highly recommend!

    My wife had been bugging me for years to do something with our old garage, but I kept putting it off. Finally, we decided to convert it into an addition, and I can honestly say my only regret is not doing it sooner! A+ handled everything from design to construction, and the transformation is incredible. It was just a cluttered storage space and now we have a cozy and functional guest suite that our family loves. The whole process was surprisingly easy, and the team was great to work with. Everyone who came to do the work was profefssional and cleaned up after themselves. If you’ve been thinking about a garage conversion, don’t wait as long as I did — call A+ ADU Builders!

    I’m so happy with the ADU A+ Construction ADU Builders built for me! I wanted something small but comfortable for my retirement years, and A+ team delivered. They helped me design a cozy, energy-efficient space, and I love how everything turned out. They were always on time, and willing to make adjustments along the way too. Now I have my perfect little home in the backyard, and I couldn’t be more pleased!

    Turning our garage into a guest suite was one of the best decisions we’ve made, and A+ Construction made it happen. The crew was on time every day, and Nikola was fantastic about communicating with us. He was always there when we needed him and answered all of our questions. We love the extra space, and it’s already come in handy for when family comes to visit. Would definitely hire them again!

    A+ Construction did an amazing job building my ADU. My friends have built an addition with A+ and were the ones to recommend them and I am glad I went with them too. The project was completed in time for our big family gathering, which was very important to me. I now have a fully functional second home in my backyard. It’s so nice that I am actually tempted to move in there myself and rent out my main house instead. It was a smooth experience from start to finish and I definitely recommend A+!

    I have been looking for a contractor to build an ADU on my property for a while. I contacted A+ Construction after seeing their great reviews online and am now happy to write another 5-star review for my own project. The crew was fast, professional, and detail-oriented. Rod helped me pick the right layout. We chose pre-approved plans from the county which saved us some time at the beginning. I am grateful that Rod suggested that. I was worried that the construction itself would be too loud and too messy, but everything ended up being pretty manageable. If you’re thinking of building an ADU, these are your guys for sure!
