      ADUs can be considered a revolution in the world of housing. The versatility of these units that are built on your lot with an already existing house is enormous. While building it doesn’t require enormous amounts of resources, this property can become a great way to start a business or simply increase the living space for your family members. Moreover, if circumstances change in the future, you even have the option to put your ADU for sale and benefit from the growing demand for these versatile living spaces.

      ADU Builders Trowbridge, CA

      Even though it may seem that building a small unit on a lot will not take much time and effort, in reality, it is a complex process that requires many steps. Hence, homeowners in Trowbridge, California, address professional general contractors who build such units for them.

      A+ Construction & Remodeling company with years of experience in the field has earned the title of the best contractor nearby and is ready to offer you services of the highest quality. Apply to our managers via the site or visit us in person and order the ADU design that will fit your wildest dreams.

      ADU Contractor Trowbridge, CA

      None of us wants to flush the money down the drain. Consequently, it is of utmost importance to find a reliable general contractor. In our view, this is not hard when you know certain requirements.

      Follow these pieces of advice to find the contractor in Trowbridge:

      1. Look through the pages on their site to check the finished projects. This will give you a better idea of the designs they provide and whether such units suit you.
      2. Deciding on your budget may help you find the right contractor. Check the pricing lists to see if the contractors ask for a comfortable price or not.
      3. Additionally, checking the reviews on the Internet is really helpful in this task. You can find these reviews on special home-building forums or on the pages of review aggregators.

      Continue reading this article, and you will learn the benefits of such units, the requirements of reliable general contractors, ADU types, and much more. However, if you already know everything about ADU building, call A+ and order a project for your future dwelling unit.

      ADU Contractor Building Types

      The companies have come up with various ADU types that can be built on your property in Trowbridge. On your request, we will build one of the following ADUs:

      • Attached ADU

      Lacking living space and want to enlarge your main house? Then this ADU type is definitely for you. We will build it in close proximity to the already existing property, so one wall will be mutual, which allows free access to the new construction. Being a bit cheaper than a Detached ADU, this variant will suit large families or seniors who require fast access to other family members.

      • Detached ADU

      This construction will be placed on your lot at some distance from the main house. However, it will possess the very same advantages as any other ADU type, like amenities and a separate entrance. The design and the process of construction may be quite expensive, though.

      • Junior ADU

      This unit is not any different from the others, but its maximum size of it cannot exceed 500 square feet. This construction can add a nice touch to your yard if the designs of it and your main house match. Even though one cannot compare it to a multifamily dwelling, it can still be a great housing option for a young family.

      • Conversion

      If you have any unnecessary rooms in your house or building on your lot, you can transform them into a modern living space. This will allow you to rent this space to the tenants, which, in its turn, will increase the family budget and help the community as well.

      ADU Unit Construction Trowbridge

      The state law imposes certain requirements concerning ADU construction that every person must follow. Before you order the ADU design from a contractor, it is advisable that you check their certificates that allow them to work in the sphere.

      The professional team of lawyers working for A+ can help you handle the issues concerning zones where one can build an ADU, as well as the requirements for it. At our request, the people in charge will have to provide this information to us. So, before we start constructing the ADU, you will get a free estimation of where and how we can build an ADU on your property.

       

      Benefits of ADU Building

      As we have already said, building an ADU has numerous advantages. The customers for whom we have already created the ADUs use them for different purposes. While some have set up a new housing business, others have created a comfortable area for their hobbies.

      The ADUs we build have the following advantages:

      1. The creation of an ADU is incomparable to building a whole new house in terms of time and resources used. It depends on many factors, but you can get an idea of how long the whole process will last after we do a free estimation at our office.
      2. The housing market doesn’t cease to grow as more and more people seek affordable housing. An ADU can help you start a new renting business that will grant your family extra money monthly.
      3. We know how anxious it may be to be the host for unexpected guests coming from all over California without warning. An ADU can provide them with comfortable accommodation overnight.

      Trowbridge ADU Construction Company

      A+ Construction & Remodeling can boast the title of one of the best general contractors in California for a reason. Actually, there is a whole list of reasons why one can ensure us building an ADU.

      The benefits of working with A+ are the following:

      • The portfolio of completed projects that we amassed during the years of working on ADU serves as proof of our reliability. Here you can see how well we work on design, how expensive our ADUs are, and how fast we build.
      • During the construction, you will be able to control the whole process. We believe that the best customer is the one who is worried about the view of the future unit. If you notice anything suspicious in the building area, tell our managers, and we will try fixing it together.
      • At our office, our skillful managers provide the clients with a free estimation. You will be able to see the needed resources and the view of your future home, add your commentaries concerning the design, and much more.

      ADU Building Trowbridge

      Apart from giving you an opportunity to start a business and create a truly multifamily housing option, an ADU can offer the owners a huge spectrum of other uses. For example, it can serve as a temporary or permanent living space for your seniors, for whom it’s better to live in the same city as you. This gives you an opportunity to provide them with proper care.

      Moreover, an ADU can be turned into a home office. If you are tired of waking up every morning just to spend an hour navigating through traffic jams, this option is for you. Turn the page of suffocating offices and work from the comfort of your home with A+!

      Prefab ADU Construction

      If you are still unsure about building an ADU, despite all of the above-mentioned benefits, perhaps a Prefab ADU is your pick. You can request to build this unit in your backyard and get access to the same benefits of any regular ADU, but for a smaller price. Access to city services and a separate entrance are included!

      However, you will not be able to apply any changes concerning the design, as you will pick only from the ADUs we have built in the past. In our turn, the company spends fewer resources on creating the plans, which allows us to lower the final cost. You can check the approximate cost on the special page on our site.

    • Frequently Asked Questions

      How long does it take to complete an ADU?

      The building time depends on various factors like materials, design, area, and many others. However, normally for our company, it takes around 7 to 10 months to complete an ADU. So if you order one in March or April, you can expect it to be finished by October.

      When is the best time to start the construction of an ADU?

      Normally, we recommend our customers set the start of the construction for spring, for example, March or April. This allows us to work on the foundation while it’s pretty warm outside. Hence, we will not need to make our way through the frosty ground. However, as it is warm in California throughout the year, we can start building an ADU in any month, be it April, July, or October.

      How can I apply for the construction of an ADU?

      When it comes to ordering an ADU, there are two main options for how it can be done. You can either come to our office in the nearest city or use our site. The latter option is really convenient as instead of spending time on the road; you can use the arrow and click on the needed sub-pages to access the application form.

      A+ Construction & Remodeling really nailed it with our detached ADU! Their team's always-on attitude was a lifesaver, and the pros at A+ not only answered all our questions, but made the whole process a breeze. From plans to final inspection - 100% great work. Plus, having a chat where we could go over pictures and get quick answers.

      A+ Construction & Remodeling helped me turn my property into a profitable investment with their ADU designed for Airbnb. The well-planned design and top-notch construction attract guests, and the extra income has been a game-changer. I highly recommend their services to anyone looking to add value to their property through short-term rentals.

      We hired A+ Construction & Remodeling to convert our garage to an ADU. Both our project manager and the construction team were pleasant to work with. They were always on time and managed to finish the project even before the deadline they set for it. We are extremely pleased with the outcome. We would recommend A+ to anyone considering a home remodel or new construction.

      A+ Construction Pro helped us transform our old garage, which was basically a glorified storage room, into a bright, open home office that fits our needs perfectly. The process was smooth, our PM Serg kept us updated, and the crew was respectful of our property. Now, instead of staring at clutter, we have a beautiful new space.

      Our 2-story ADU by A+ Construction is great! They are total professionals. They not only found a way to get the most out of our backyard space, but also took care of plans and permits, so we didn’t have to worry about any of it! Our PM Nick and the rest of the crew were the best. I definitely recommend A+ to anyone looking to build an addition!

      Finally, we decided to turn our old garage into additional living space, and I wish I’d done it sooner! A+ handled everything from designs and plans to permits and construction, and the transformation is incredible. It was just a cluttered storage space, and now we have a functional guest house that our family loves. The whole process was stress-free, the ADU was completed in time for the holidays, and the team was great!
