    It is not possible to anticipate how much living space we actually would need in the future, which is why it is normal for homeowners to find themselves in a situation where their house is no longer as spacious as it once was.

    Two possibilities are available for those who desire to increase their living space in Nicolaus, Sutter. The first one is to sell the current house and buy a new one in another neighborhood. However, this is not the option that many people can afford or even want to choose. Another possibility would include assembling an Accessory Dwelling Unit, or ADU. ADU construction California is a viable solution for homeowners looking to expand their living space without the need to relocate.


    ADU Builders Nicolaus,CA

    The common opinion that Accessory Dwelling Units are different from traditional homes and could be built without professional help is actually not true. ADUs are exactly like your primary houses, and their size only makes the whole building process that much harder!

    When everything is decreased in size, you are left with no room for mistakes, which is why creating ADUs on your own would only increase the construction period, create a lot of mistakes to be fixed, and hence, require a bigger budget for the completion.

    Working together with professional contractors like A+ Construction & Remodeling is a win-win situation: you still get to decide on the size, type, and design of your future completed projects, but all the hard work that should be done for an ADU to be built will be given into the hands of professionals.

    ADU Contractor Nicolaus, CA

    Knowing the types of ADUs that can be created on your property is not enough for the projects to be finished. You also would need to choose a general contractor to do the job for you, and it is not an easy task. Never choose a contractor to be contacted by you on the first try, as the risks of ending up with a horrible new piece of property are too high!

    Here is the list of some properties that you should pay attention to while searching for contractors to complete your ADU project:

    1. The license of a contractor is one of the first properties that you should pay attention to in your search! Without a proper license, you can never be sure of the quality of services provided by the company in your ADU project, as well as sue the contractors in case some serious mistakes were made. Always put the safety of your family first;
    2. No matter how much you like the team that you consider working with, you still need to make sure that they are capable of doing the exact projects that you need! Always check the portfolio of the company under your consideration. There you should see examples of project types similar to yours. What is more, a portfolio is also great for understanding the overall design preferences that the contractors have so that you would only hire those contractors that coincide with your own design ideas;
    3. A free estimate is always a good representation of the company that you are dealing with. Free estimates of the projects are given out only by those contractors that are honest with their pricing and do not drastically change the list of services that would be required during the construction process, so look for the companies that provide them to the clients;
    4. Verify as many reviews as possible, do not stop only on the online ones. It is always better to ask around your friends, relatives, and neighbors about their collaboration experience with construction companies. That way, you will always receive an honest opinion as well as have a chance to ask the questions that you have and get a good piece of advice.

    Fortunately for you, all of these properties are already provided by A+ Construction & Remodeling in Nicolaus and in Sutter County, which is why you might want to start your search process by considering this company for the job!

    ADU Unit Construction Nicolaus

    Another crucial subject that most homeowners do not know about is that ADU projects are regulated by the California building code. Hence, for you to construct a legal new property, building permits should be received from local authorities in the state of California.

    What is more, a lot of cities have adopted their individual ADU regulations that differ from those made by the state, which is why it is hard to deal with and comply with them for any homeowner.

    It is better to trust the entire process to professional construction companies that A+ Construction & Remodeling that have a lot of experience dealing with local authorities and can therefore speed up the entire approval process.

    Accessory Dwelling Units are autonomous small dwellings that are formed on the same land where your current property stands. They have all the same utilities (bathrooms and kitchens) and bedrooms as your own houses, only in a smaller size.

    If you are interested in learning more about the ADU building process in Nicolaus, California, that is done together with contractors or even an architect; then we would suggest you keep on reading this article!

    ADU Contractor Building Types

    Those of you who do not know anything about ADUs will be even more thrilled to learn that Accessory Dwelling Units can be of distinct kinds, with each of them being picked by owners relying on their needs.

    Here is the list of the most prevalent Accessory Dwelling Unit kinds:

    • Junior ADU

    Junior ADU is the most miniature type of construction project that could take place on your land. What is more, it will not even need new structures to be built as it will convert the ones that you already have but do not use, such as your basement, attic, or garage.

    This type of Accessory Dwelling Unit should be picked by those who do not need much area added to their property or would like to use it for some unnecessary everyday activities. For instance, a junior ADU is an excellent place to create a small home cinema, a gym, or even a band rehearsal place.

    • Attached ADU

    The attached Accessory Dwelling Units are nothing like junior ADUs: they are greater in size and are assembled outside of your main dwelling. Nevertheless, they still are not completely independent, as they would need to share one wall with your primary residence.

    The attached Accessory Dwelling Units are ideal for those Nicolaus homeowners that want to add more space directly to their house. For instance, an attached ADU is a good idea when you want your home to be extended so that separate rooms for your children can be created.

    • Detached ADU

    Detached ADU is the largest type of project that you can assemble on your property in Sutter County. Such completed projects would stand independently of the main dwelling and have the biggest possible square footage.

    As you can guess, detached ADUs are the most private ones, they are also often called “backyard cottages” and could be utilized for the greatest variety of reasons. You can even rent them out and receive additional income! It is also a perfect place to accommodate your guests or to throw a barbecue party in the summer.

    As you can see, any type of project that you would choose to create requires a lot of complicated skills to be obtained, and it is usually the case that homeowners do not have them. Hence, it is always better to trust an ADU construction process to professional contractors in Nicolaus, California, like A+ Construction & Remodeling!

    Benefits of ADU Building

    We all build ADUs because of the need to receive additional living space on our property, but did you know that an ADU can have lots of other benefits as well?

    Here are some advantages that our clients from Nicolaus and overall from the state of California have mentioned:

    • New construction processes usually bring more benefits to our land than expected. For example, it is common for professional contractors to do some preparatory work on your land before the construction of an ADU even starts, which is why you can expect your contractors and maybe even architect to improve your lawn or fix some cosmetic shortcomings of the main dwelling;
    • Another great advantage lies in the fact that there is no building that could be created faster than ADU. Hence, you will not only receive the cheapest addition of space, but also will have a chance to use it once the smallest possible construction period is finished;
    • ADU is never a waste of your money. No matter what your initial aims for the new construction process are, you will always have a chance to repurpose your ADU and turn it into something else without spending any more money.

    Nicolaus ADU Construction Company

    All homeowners feel scared the first time they trust their property into the hands of some strangers, and they have every right to be! They do not really know the contractors they will be working with and would not have an opportunity to control them 24/7.

    A+ understands that, which is why its contractors always make sure to keep in touch with the clients on a daily basis so that every construction stage is clear to them and all the worries are eliminated.

    Here are some reasons why others choose A+ as the contractors for their ADU projects in the state of California:

    1. The company has a lot of experience in the field, and all of its workers are highly-experienced contractors that are constantly updating their skills and knowledge. Hence, the projects completed by A+ and its contractors are always of the highest quality;
    2. You are always welcome to check the photos in our portfolio and see just how many different projects we can make and in what variety of designs they are implemented. We are constantly updating our portfolio with new photos so that you can see with your own eyes, the freshest works of our contractors and ensure that our services are worth being paid for;
    3. You can always expect to receive a free first consultation with us that could help you to cover all the questions that you have, as well as give the contractors a vision of the type of project to be implemented. A free estimate is also a feature that we provide to ADU clients;
    4. A+ has always been a client-oriented company, which means that the contractors establish all of their decisions on the desires and needs stated by you in advance. Such an approach allows our contractors to always satisfy each client 100%!

    ADU Building Nicolaus

    The decision to move forward with your ADU project idea creates a multitude of possibilities for you! As we have already said, any ADU can be quite a versatile piece of property that you can use however you want throughout your life, which is why it is always a good investment in your future!

For instance, you can use the same ADU in Sutter County to accommodate your elderly, guests, and friends or even rent it out and receive additional income.

    Prefab ADU Construction

    The last type of ADU that we have not yet covered is called a prefab ADU. And in comparison with more traditional custom choices of an ADU, a prefab one is built in professional factories and then transferred to your property.

    A prefab ADU can still be detached or attached, but it would lack the variety of design options that custom Accessory Dwelling Units have. You still will have a great number of designs to choose from, but you will not be able to design your ADU from scratch.

    For some people, it is still the best option, as they care more about the fact that this is the fastest and cheapest ADU construction process than about the possibility of styling their new piece of property.
