    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 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.


    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.


    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.


    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.
