    Homeowners for many years have been looking for ways to get more space on the territory of their property and do not even realize that among all the options, the most affordable and perfect is the construction of an Accessory Dwelling Unit or ADU.

    This is an autonomous residential unit, which is equipped with all basic life support systems and is characterized by increased functionality and comfort. ADU can serve any household purpose; with its help, you can receive guests at any time of the day, spend more time with your family, or just relax.

    In this review, we will talk about the types of ADUs, present a full list of their advantages, and also share information about a professional team that can build accessory dwelling units in Sutter, California, at the highest level.

    ADU Builders Rio Oso, CA

    There are a large number of different configurations of accessory dwelling units. All of them differ in functionality and layout and have unique characteristics that attract the attention of every homeowner in Sutter, California. We have collected the most in-demand options for you.

    Attached ADU

    This accessory dwelling unit differs in the fact that it has a common border with the primary residence, passing through the wall; in addition, the points of contact can be on the roof and foundation. The main goal of attached ADUs is to expand existing space in a situation when, for example, your children have grown up and need different rooms or when you have switched to a remote work format, and you cannot do without a home office. The range of applications of attached ADUs is limitless and is determined by your imagination and needs.

    Detached ADU

    This type of ADU is located separately from the main house and can be placed both in the backyard and in the foreground; however, in this case, it is necessary to attach the parking lot by all the laws of the city. Most often, detached ADUs are used to accommodate guests who have decided to come for a weekend or as a permanent home for age-related parents since this is the most preferred option when relatives live on the same territory but keep their borders intact. Detached ADUs are equipped with all the necessary life support systems to maintain living standards at a high level.

    Garage Conversion

    Most property owners will tell you that the existing garage is the most cluttered place in the house, which is regularly filled with boxes of old things or books. This situation will not bring any benefit, unlike the garage conversion project. In place of the old parking zone, you can create a home gym, an art studio, or any additional room, be it a bedroom or a laundry.

    Basement Conversion

    The essence of this accessory dwelling unit is very similar to the previous position because, from a little space, builders create an authentic and aesthetically beautiful place that you will want to visit every day. It can be a relaxation room after a hard day’s work, a space for family pastime, or yoga classes. In addition, the basement can be equipped with some unusual chips, for example, an artificial waterfall from ceiling to floor, a small fireplace, or neon lighting.

    Junior accessory dwelling unit

    From the name, we can conclude that this project has the smallest area, and it is true. Most often, the minimum lot size of junior ADU is 200 square feet, and the maximum value rarely exceeds the threshold of 500 square feet. However, this does not negate the fact that a junior accessory dwelling unit is one of the best ways to get more space quickly and at a bargain price and solve one or several household tasks at once.

    All in all, the list of projects is not limited to these five positions. However, to be fully satisfied with the quality of the constructed building, you need the services of a general contractor, and in the next part, we will tell you how to choose the ideal company.

    ADU Contractor Rio Oso, CA

    In various resources, you can find many examples of how one amateur builder does major repairs alone. Some homeowners have an idea that they will also build an entire project without outside help; however, this is not the case. The construction process is like a clockwork mechanism, and if at least one cog is out of place, then nothing will
