    California is one of the best places to live, with its gently sloped country land, developed highway system, and good schools to educate kids. It is no surprise that a lot of people want to relocate there. You can expect your relatives to come to visit or move in with you, but where to house them?

    An accessory dwelling unit is becoming quite a popular project idea nowadays. It is an incredible opportunity to add a bit of space to your house and increase its value before selling.

    Accessory dwelling units are small houses or apartments that can be either attached to the main house or stand separately in a backyard. This solid construction is supposed to have its own bedroom and a primary feature, but if the space allows, it can contain a bathroom with a bathtub or a shower and a kitchen as well.

    The reasons behind building an ADU are quite different. Some homeowners are about to move in with their aging parents; others wish to have some extra space for growing kids or have proper guest quarters that will give both family and visitors enough privacy and independence.

    In this article, we will dive a little deeper into the advantages and disadvantages of having an ADU, look at the services that you may expect to get from a remodeling contractor in terms of building an ADU, and give some advice on how to hire a decent ADU for sale contractor near you.

    ADU Builders Newcastle, CA

    Many people are a bit afraid of building an ADU because they tend to think it will take up a lot of space, become a drain on the budget, or will be an unnecessary investment that no one will make use of. It is true that building comes with some challenges, but overcoming them will pay off in the long run.

    It may come in different forms; for example, you can repurpose a gated garage or place an ADU in the backyard outlooking the garden. One or two bedrooms in accessory dwelling units are a must, but they are spacious enough; they can also include bathrooms, kitchens with kitchen cabinets, and other features.

    In order not to get cold in the winter, think of an inside room heating that can be a part of a central heating system or get warmed up by a small heater (or even a wood-burning place!).

    And if you are planning an ADU for your aging parents or in-laws, you might want to think of wheelchair access to the property to make it most convenient for the elderly.

    Below we are going to look into the benefits and drawbacks of having an ADU that stands out or is attached to the wall of your house.

    Pros of having an ADU

    The advantages of building an accessory dwelling unit are numerous, and here are only some of them:

    • To start with, if your family is big, it may prove difficult to find a private space for each family member in one house. For this reason, an owner of the house might want to embark on building an addition.
    • Also, some can consider an ADU as a long-term investment and expect to get some rental income from a newly-built property. Rather than maintaining an empty space for no reason, why not rent it out and earn extra money with it?
    • An ADU is considered to be a living area, but it can also serve multiple purposes. If you love painting, you could set up an art studio there, or if you are working from home, it can double as a tiny home office that will boost your efficiency and productivity.
    • In case your home is a magnet for visiting friends and relatives, you can house them in an ADU for a night or longer periods of time. This way, you will ensure more privacy both for your family and guests rather than making them sleep on the sofa on the ground floor and run into each other in the morning.

    Cons of having an ADU

    Although accessory dwelling units come with a bunch of advantages, there are still some things on the flip side to keep in mind before deciding on building it:

    • The space you allocate to building an ADU can serve another purpose; for example, you may benefit more from having open parking spaces or a pool in place of it.
    • Since it is another living area, you will need to give it the necessary level of care and maintenance. It is not only about washing the floor or vacuuming the carpet; it also involves renovation and remodeling from time to time.
    • It may cost quite a lot, and the price will vary from project to project, but still, think carefully about whether you are ready to pay extra taxes and insurance in the future.

    ADU Contractor Newcastle, California

    Any building process involves a lot of different things related to complying with the law, zoning requirements, picking the right materials, and actually building the required construction. If you are not an expert in all the areas mentioned above, you will definitely benefit from contacting a professional contractor who has enough experience to make your new property both legal and nice-looking.

    Any realtor, or a real estate agent, will tell you that it is of utmost importance to have all the documents in order if you decide to rent or sell your house. In case you fail to do so, you may face a lot of challenges when dealing with the repercussions of an unlawfully built ADU.

    A good service provider will first hear you out and get an understanding of what kind of apartment, house, or family room you are aiming to create. Next, they will assess and evaluate the cost of the project and give you a preliminary estimate so that you can plan your budget well in advance.

    And it also will not be you who will have to deal with local authorities and lawyers to deal with the documentation and requirements. A chosen contractor will take this on them, and you can just relax waiting to see your new home in a designated amount of time.

    ADU Construction Company Newcastle

    There are a lot of providers in Placer County, but what is it that makes a reliable service provider?

    First and foremost, a professional provider has to know the ins and outs of building codes in the Sacramento area. Without this knowledge, it will be hard to build an ADU meeting all the standards.

    Secondly, they need to possess certain licenses to be able to perform in a building. And finally, they are supposed to provide excellent customer service without delays or unexpected expenses.

    To find a good provider, you can ask around in the neighborhood or contact your family and friends. Alternatively, go online and search for the companies that provide the services you are looking for. Be sure to read the reviews carefully, check their price policy, and, if possible, look at the completed designs.
