      One day you may understand that your existing living space is not enough and you need to enlarge it somehow. If so, there is one proven and convenient way to do that: you can build an accessory dwelling unit, shortly called an ADU.

      If you reside in Vallejo or any other area of Solano county, you might have seen such buildings around. They are typically smaller than primary housing and can be attached to houses or stand separately. Homeowners build them for different reasons and often prefer their creation to sell their existing property and buy new homes.

      We have prepared this guide for you so that you receive all the necessary information about building a Vallejo ADU, finding a professional company that will become your builder for the project, and the benefits that accessory dwelling units bring into your life. Whether you want to increase your living space, accommodate family members, or generate rental income, ADU in Sacramento can be a valuable addition to your property.

      ADU Builders Vallejo Solano, CA

      In California, there are four types of ADUs allowed and common. When you start thinking of an accessory building next to your primary home, the first thing you should do is define the type that suits your needs and preferences.

      You can select from the following types for your unit in Vallejo:

      Detached

      Detached ADUs are those built separately from primary housing. If you have a single-family home with no spare rooms but need some extra living space (for instance, for your parents), a detached unit is a fantastic option for you. People often call them “granny flats” because they build and use them for their parents and other senior relatives.

      Attached

      On the contrary, an attached ADU shares a wall with your existing home. It works perfectly if your family is expecting a child and you want to create a separate room for them right away.

      Converted

      This type’s name gives us a hint — when we say converted ADU, we mean that it used to have other functions and looks before but has existed as a structure for quite a while. Normally, a garage becomes a converted accessory unit because it is so easy to remodel it.

      Junior

      These units have certain size requirements: no more than 500 square feet. If a unit is bigger, it cannot be considered a junior one.

      Generally, ADU is a rather affordable housing that can help you in numerous situations. To make your unit solid and reliable, you’d better find a professional builder that will be responsible for the whole project. Check our recommendations below.

      ADU Contractor Vallejo Solano, CA

      A qualified builder is essential when we talk about creating a Vallejo ADU in your property line. Hiring a team of specialists who know what they are doing is much better than trying to figure out your ADU project step by step and complete each stage on your own.

      The property owner gets plenty of benefits when they sign a contract with a construction company for an accessory unit creation. The company takes full responsibility and builds the structure from scratch — and the property owner does not have to worry about it.

      Here are some vital points you have to check before you sign a contract to build a unit in Vallejo city, Solano county:

      Recommendations from people you know

      Construction and remodeling works are quite common because people often wish to change something in their existing housing or build something new. Probably, during the last couple of years, someone you know has done some renovations. Try asking them for advice regarding a company they have worked with and its building division expertise.

      Online reviews

      Another way to find a trustworthy company in your city is to check various comments online. Pay attention to the negative ones: it will help you avoid the tragedy of hiring inexperienced or dishonest businesses.

      Gallery of completed works

      Remember to check a company’s portfolio to ensure that the team has enough expertise to provide you with top-notch service. Also, it might happen that your vision and style do not coincide with the company’s views and opinion on design, and you will understand that from looking at their gallery.

      License

      Businesses that work in engineering and construction fields in California must have certain permits and a license so that they operate lawfully. Do not forget to ask about it before signing a contract. Without permits, it will be impossible to complete your structure creation.

      All these factors affect the success of your project and its completion, so do not neglect to check the above-mentioned information about each company you consider for your remodeling and construction projects in California.

      ADU Unit Construction Vallejo, Solano

      Because an ADU is normally a residential property, there are certain regulations that residents should obey when they start their projects in California (and Vallejo city, particularly).

      For instance, in most cases, the maximum height of an ADU in the state should be 16 feet (there are exceptions — you can check them with local authorities). A residential ADU must have a minimum lot size of 150 square feet; however, it cannot be over 1000 square feet.

      There are more rules regarding setbacks, parking, and other aspects; we will not define them in this review, but you must keep in mind that they exist and familiarize yourself with them.

      Another essential thing is that you have to get a permit for your ADU regardless of the town in California you reside in. Although it might seem a hard task, if you hire a company that will build your unit, it will assist you with getting a permit. Also, it will construct your unit in accordance with fire safety rules and other regulations.

      If you hire a team of professionals to complete your project, you will surely get a unit that will be built properly and there will not be any problems in the future.

      Benefits of ADU Building

      Building an accessory unit is extremely beneficial, and here is why:

      You enlarge your living space

      This factor always gives you more opportunities for yourself, your family, and your friends. Many families build ADUs in Vallejo city because they feel a lack of space. A well-made unit solves the problem perfectly.

      Your custom unit can be used as a home office where no one disturbs you or a room where you spend time blissfully with your favorite hobby (like painting or sewing, which often requires additional space); you can also host a long-term party, and your unit will become a guest house.

      Lastly, a unit is perfect for your parents or grandparents to move in and reunite with your family. If you have a single-family home without many rooms, having a spare property for seniors makes a lot of sense. Their proximity to you will ensure that you will be able to care about them anytime.

      You can organize long or short-term rentals with bigger fees

      Renting out is becoming more and more popular among those who can afford more real property. If you are tired of your existing home or wish to move out and change your address due to other reasons, you can rent it and make the rent price higher with a good-quality custom unit.

      Your residential space becomes attractive for sale

      A residential property sale is another level where you get benefits. It is a serious event, and owners normally want to make the deal extremely profitable — an ADU will help you with that.

      In all cases, the A+ Construction & Remodeling company will provide you with the best service and construct a delectable accessory unit for you.

      The plan is the following:

      1. On-site meeting

      In the beginning, experts from the team arrive on-site to see what they will work with. Depending on the soil and surroundings, they decide what materials to use and how to build your unit and make it solid.

      1. Design planning

      Designers, together with architects, will develop your unit’s plan.

      1. Building

    • Frequently Asked Questions

      Why should I build an ADU in Vallejo city?

      Getting an ADU will help you enlarge and improve your living space; it can solve many problems that modern families have. For example, you can use a unit as a place where you will work instead of going to the office if your boss allows you to work remotely. Also, you can ask your parents or grandparents to move in with you if you worry about them. These are just examples; there are many other benefits of ADUs for homeowners.

      How long does it take to finish an ADU project in Vallejo?

      The term depends on the unit you build. If it is something massive, you should plan at least a year to complete it. Moderate units will take about six or eight months. If you opt for a prefab unit, the term will be smaller.

      How much does an ADU in Vallejo city cost?

      On average, you should be prepared to pay 200,000-300,000 US dollars. There is no uniform number that answers this question: each unit has unique features, size, and, therefore, cost. When you turn to your local contractor, normally, its managers are capable of counting the approximate price for you; remember that it will probably grow because some details might not be considered from the start.

      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.

      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 commented on how seamlessly it blends in with the main house, which was important to us.

      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, 10 out of 10! The workers were skilled and easy-going. After they finished our ADU, my in-laws decided to have them start on a project at their house too.

      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 Serge kept us updated, and the crew was respectful of our property. Now, instead of staring at clutter, we have a beautiful new space.

      Finally, we decided to convert our old garage into an addition, and I can honestly say my only regret is not doing it sooner!

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.

      A+ Construction did an amazing job building my ADU. My friends built an addition with A+ and were the ones to recommend them, and I am glad I went with them too.

      I contacted A+ Construction after seeing their great reviews online and am now happy to write another 5-star review. The crew was fast, professional, and detail-oriented. Rod helped me pick the right layout, and we chose pre-approved plans from the county, which saved us time. The construction was manageable and not as disruptive as I expected.
