      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 work.

      Repair, as well as the implementation of the draft ADU, cannot do without the services of high-class craftsmen who will save you from losing emotional and physical strength, help you preserve money, and at the same time, make an ideal ADU.


      ADU Contractor Rio Oso

      Many property owners think that choosing a remodeling company is one of the most difficult stages of implementing an ADU project; however, if you have certain knowledge, then it will be easier for you.

      It is enough to analyze the following three parameters:

      • Study the background. Before you hire a contractor and sign a contract, it is necessary to review the portfolio to assess the quality of completed projects. At the same time, pay attention to those buildings that are similar in structure and layout to your future ADU.
      • Check for a license. The activities of each contractor must be regulated by the laws of the city or state. You cannot do business with a company that does not have a permit to provide construction services, so check for a license.
      • Talk to neighbors and residents of the area. The opinion of people who have already interacted with a particular company in the past speaks best about the quality of services. Visit your friends, colleagues, or neighbors who have recently implemented an ADU project to learn about the manners and professionalism of builders and clarify the monetary issue.

      Overall, surprisingly not many companies meet all three criteria. To save you time, we will say that in Sutter, California. You will not find a better contractor than A+ Construction & Remodeling, which is famous for the top level of completed projects.

      ADU Unit Construction Rio Oso

      The construction of accessory dwelling units should be allowed by state law. However, there is a small snag here. The fact is that, in most cases, an ordinary homeowner does not know all the nuances of state law because different rules apply to each ADU project. For example, in the case of basement conversion, it is necessary to fit into the framework of the minimum and maximum lot size, install fire sprinklers in the right places, zone the room, and adjust the ceiling height.

      If we are talking about detached ADUs, then for single-family and multi-family houses, different rules apply from city to city. All this leads us to the conclusion that it is crucial to interact with lawyers. The A+ company employs highly qualified specialists who will help to issue all building permits, protect against construction bans and conduct free consultations.

      Benefits of ADU Building

      With all the agendas which are dedicated to deciding on the construction of an ADU, the question arises of what advantages this building has. Here we can say that the list of privileges is so long that it is not possible to mention everything at once.

      We have selected five of the coolest benefits for you:

      1. Increasing the monetary value of the property. All kinds of ADU projects mentioned above can upgrade the value of your entire property by several tens or thousands of dollars. Buyers like everything that differs from standard plots, so the presence of ADU as part of the property will make your house a tasty morsel in the real estate market.
      2. A win-win investment. From the point of view of arithmetic and numbers, buying a new house or a long repair with your own hands are unprofitable investments, unlike ADU. For a relatively low price, the construction team will build an ADU, which you can use for many decades.
      3. Getting rental income. If your ADU stays without constant use, then you can rent it out. The money that tenants will pay will permit you to quickly recapture construction costs and receive passive income.
      4. Realization of dreams. In the past, each of us dreamed of some unusual room in the house, for example, for hobbies, displaying a collection of paintings, or watching movies on the big screen. ADU allows you to make a dream project out of existing space.
      5. Strengthening the family. A single-family home in the backyard will be the space that every family member will like. Here you can have fun together, communicate, and have a great time, which will undoubtedly have a positive effect on strengthening family ties.

      In total, in the following parts, we will tell you even more about the advantages of ADU. However, it is important to understand that to use them; you need to find a good building company that can complete construction on the top level. In Sutter, California, such a team is A+ Construction & Remodeling.

      Rio Oso ADU Construction Company

      When building accessory dwelling units, it is very important to form a trusting relationship between builders and the client, which has a very positive effect on the final result. However, contrary to this axiom, some companies do not seek to work closely with homeowners.

      A+ Construction & Remodeling think differently:

      1. Productive free consultation. Usually, a free consultation is limited to getting to know the team and presenting a price list. However, in the case of A+ during the initial negotiations, you can present all your ideas about the draft and share any worries. In turn, representatives of the company will help to plan the budget correctly and give valuable advice, for example, where it is better to buy materials.
      2. Individual approach. The A+ team consists of architects, designers, planners, and builders with a high level of skills in their profile. Each person can get help from a specific specialist. For example, if you can not decide on bedroom wallpaper, then our designer will always respond to your dilemma.
      3. Making adjustments. At any stage of the project, you can contact the builders with a request to make changes. If the proposal improves the final version of the ADU, then the specialists will be happy to implement your idea.

      On the whole, you will not find more professional and at the same time responsive builders who will help you create your dream ADU from the unsightly existing space. You can visit the A+ office to get a free estimate or call a phone that can be found online on the web page.

      ADU Building Rio Oso

      A little earlier, we mentioned that ADUs have the widest range of advantages, and now it’s time to prove it. In addition to the positions that we presented, it is worth mentioning, firstly, a home theater. In place of the old basement, you can create a home theater with surround sound and even a 3D format.

      Secondly, ADU can be an ideal place for children’s educational games. After purchasing a Swedish wall, a small trampoline, and board games, children will communicate more with each other and explore the world more actively.

      Finally, one of the variants of ADU is the man cave. You can equip the space with a billiard, mini-bar, table football, or tennis, hang posters of your favorite sports teams, and organize a place to play computer games.

      Prefab ADU Construction

      If you are looking for an ADU construction option that does not require additional costs for replacement parking or the services of architects and designers, then we recommend taking a closer look at such a variant as prefab ADU. This is the same ADU, with the only difference being that it is fully or partially assembled at the factory and then delivered to your site, and all that remains for the builders is to put all the details together, as in the Lego constructor.

      Prefab ADUs are distinguished by a fast installation period, low construction costs, and increased safety, as durable panels can withstand any abnormal weather without damage. In prefab ADUs, all family members will feel as comfortable and safe as possible.

      ADU Housing

      If a person decides to get an ADU on the site, then this may be the best decision in his life. ADU will permit you to take the comfort of living conditions to a new level and open up many household opportunities. For the ADU to meet all your expectations, it is best to contact professional employees from the A+ team who perform an amazing job. Call our managers by phone or visit the office in Rio Oso city to get a free estimate.

      Frequently Asked Questions — FAQ

      What is the need for legal services in the construction of ADU?

      A professional lawyer will help you get a building permit asap and avoid a ban on construction. In addition, the lawyer knows the details of each state law regarding ADU, for example, the difference in the permissible height of single-family and multi-family houses, which will help to properly conduct property lines and comply with all requirements.

      What are the advantages of owning an ADU in Rio Oso city?

      Even the minimum size ADU can significantly increase the cost of private property, make the living space more functional, add coziness and comfort, and also allow you to receive passive income for renting out the premises.

      How much does ADU construction in Sutter, California, cost?

      It is impossible to give an unambiguous answer to this question because the final price tag is formed, first of all, from the size of the ADU and the complexity of its design. We can only indicate approximate figures; for example, the cheapest option is junior ADU, the most expensive two-story detached ADU, and somewhere in the middle is attached ADU.
