    The most cherished dream of every homeowner is a custom house because it is a living space that has a unique interior design, unusual layout, and the location of rooms. However, most houses have standard parameters that do not differ in originality.

    One way to take a step forward toward the custom home is to build an ADU. The accessory dwelling unit is a residential area that, like the main house, is equipped with all life support systems and can perform many helpful functions. To bring your dream of a custom ADU to life, it’s essential to work with a professional ADU builder.

    ADU Builders Foresthill, CA

    The intention to create a dream home with the help of the realization of an accessory dwelling unit project is a commendable decision. However, the same cannot be said about the situation when the homeowner decides to do it alone. At first glance, it seems that after reading a couple of guides and watching a few popular videos, you will become a professional in the remodeling business. Nevertheless, this is not the case.

    It is impossible to study all the nuances and pitfalls of installing plumbing or electrical systems in a short time. Most likely, you will make a mistake that can lead to fatal consequences. For this reason, it is necessary to implement the ADU project in cooperation with the construction company.

    In Placer, California, a large number of custom home builders can provide ADU building services, so keep reading our review to find out how to identify the best contractor.

    ADU Contractor Foresthill, CA

    The most important step in the implementation of the ADU project is the signing of a contract with the developer company. However, there is a reasonable question, how to pick the best contractor among all available in Forest Hill? It is not as difficult as it seems at first glance.

    The following parameters will help you choose the right firm and filter out other contractors:

    1. Money question. The best general contractors are distinguished by transparency in matters of budget formation. They will not delay providing estimates or try to impose additional costs for an unnecessary job.
    2. Analyze the formal documents. The list of such papers may include a construction license, a project declaration, or a permit to carry out activities. Do not forget to look at the expiration dates of licenses. The bonus will be the presence of certificates and awards confirming the high quality of remodeling services.
    3. Study the history of completed projects. To do this, you need to go to the custom home builder website and see what projects the company carried out. The contractor also should have experience in providing ADU services. Even better, when all the details of completed works are published on the site in the format of video and photo reports.

    Furthermore, a crucial indicator of the company’s excellent job is its reputation among the people who did the custom house together with this firm. You can ask your neighbors about this, and it will turn out that the best contractor that meets all the parameters is A+ Construction & Remodeling.

    ADU Unit Construction Foresthill

    The legal aspect of ADU construction is another good reason why you should think about hiring home builders. The wording about the zoning of the territory, maximum required setback values, parking space sizes, ceiling heights, and security measures differ depending on the location of your home in California. In this regard, you will need at least one consultation with a lawyer from the contractor’s company.

    In this aspect, we can say that the firm A+ Construction & Remodeling performs not only high-quality work in all popular locations nearby Foresthill but also has lawyers with world-class experience in its team. They will conduct an inspection of the site and contact you if there is a need to make adjustments to the process.

    In this review, we will analyze what stages the ADU construction process consists of, what types of accessory dwelling units exist, and which contractor among all home builders provides the highest quality building services.

    ADU Contractor Building Types

    All types of ADU can be grouped into five main categories, each of which has a unique set of characteristics and perform various household functions.

    • Detached ADU

    This is a fully autonomous building, which is located separately from the main house and is equipped with all the basic rooms for a comfortable life. It can serve as accommodation for family members who have come to visit, as a place to relax, or as a home office for business affairs.

    • Attached ADU

    Such an accessory dwelling unit is a continuation of the main house; that is, it has a common wall, foundation, and roof with it and retains the integrity of the entire residential structure. This is a great way to increase the area of the property for very low pricing. An important detail, as the owner, you can choose from two scenarios, either the attached ADU and the main house will have different entrances or adjacent so that you can get into the room without going outside.

    • Garage conversion

    Almost every homeowner is not satisfied with the condition of the existing garage, and one of the ways to solve this problem is to re-equip it. There are a huge number of options, a hobby garage, a man cave, a home gym, and much more. The choice of a specific configuration of conversion depends on your needs and imagination.

    • Junior ADU

    This accessory dwelling unit has the smallest area, so it is classified as a single-family home. In this regard, such a project is quite simple and quick to implement, and to recoup the money spent faster; you can rent it out to a young family.

    • Two-story ADU

    In contrast to the previous position, this is the largest project. This multi-family lot is equipped with two bathrooms, several bedrooms, an extensive hall, and a large kitchen. Moreover, if desired, you can create an attic for children’s games or storage of family items, as well as a cellar for wines or other elite drinks.

    All in all, of course, the choice of ADU types does not end there, and if you want to continue the search, then visit the A+ website, where the widest range of ADUs is presented.

    Benefits of ADU Building

    Accessory dwelling units have a large number of advantages, some of them are not even suspected by homeowners, so we decided to collect all the most amazing privileges of ADU construction.

    We have a list of five factors:

    1. Low price and small investments. From the point of view of simple mathematics, the building of ADU will cost at least three times less than a whole house remodels and five times less than buying a new house.
    2. The embodiment of all desires. If you dreamed of adding a unique feature to the layout of the house, for example, a secret closet or a cozy attic, then ADU gives you this opportunity because custom home builders, in particular A+, are ready to implement all your great ideas.
    3. Improving the functionality of the property. ADU can become a place for recreation for all family members, work, creative activities, cool pastime with friends, accommodation in comfortable conditions of age-related parents, and much more.
    4. Increasing the value of the property. The presence of an additional building on the main plot instantly increases the price tag on your property and the interest of buyers because everything that differs from the standard layout is expensive.
    5. The possibility of passive income. To quickly recoup the funds spent on construction and services of custom home builders, you can rent out a new ADU and receive additional income.

    On the whole, if you are interested in the prospect of using the advantages of ADU, then besides developing the concept of a future project, you need to find a top-level company, which is A+ Construction & Remodeling. This firm is distinguished by its high-quality finished product, a professional approach to business, and incredible customer loyalty not only in Placer county but also in other nearby locations.

    Foresthill ADU Construction Company

    Even the best custom home builders have one negative characteristic, in particular, the low level of customer involvement in the process of implementing the accessory dwelling unit project.

    Fortunately, compared to such general contractors, A+ has a completely different approach:

    • Effective first consultation. Already at the first meeting, you will have the opportunity not only to receive a free estimate and get to know the staff but also to offer all your ideas and share worries or suggestions. Our managers will listen to all your wishes and then make every effort to realize them.
    • The ability to make amendments. Even after the plan, budget, and schedule of works are approved, you can make adjustments since you are the owner of the premises. While other custom home builders distance themselves from customers, A+ always listens to homeowners at all stages of renovation.
    • Working with the team. The A+ team consists of professional architects, designers, engineers, electricians, and builders. You can contact each of the specialists to discuss some solutions, for example, which type of roof to choose or which pictures are suitable for the interior of a particular room. Our masters will share their knowledge to make the project perfect.

    Overall, great customer service and professionalism at all stages of the project are the basic principles of the A+ team. You can be sure of high-quality completed work and the realization of all your ideas and desires. You can not find a better custom home builder, so come to our office to get a free estimate or contact our managers by phone.

    ADU Building Foresthill

    If by this part of the review, you have not formed a firm desire to become an ADU owner, then the following three reasons will finally tip the scales in favor of the decision to implement the reconstruction project together with the A+ team. Firstly, when expanding a family, ADU can provide valuable additional space for a children’s room, storage of different things, or extracurricular activities.

    Secondly, if you have always dreamed of doing some kind of craft or art, then ADU is perfect for this purpose. You can create pottery or a wood carving workshop. You can open a small gallery of your paintings or your children’s creativity.

    Finally, ADU can be used as a place to relax and find harmony with the world. You can equip a yoga space to practice meditation or hang a hammock to enjoy peace after a hard working week.

    Prefab ADU Construction

    If you do not want to spend money on the services of architects or designers who will give you advice on which siding is best to choose or which framing is currently in fashion, you can turn to an option called prefab ADU. The essence of this service is that the ADU is manufactured at the factory and then, in one of three forms – in parts, modules, or in whole – is delivered to the landlord’s site. This is a very efficient way in terms of time spent.

    Moreover, it does not require lengthy consultations and negotiations with contractors because you simply choose the configuration you like, and after a certain time, the ready-made ADU will stand in your yard.

    ADU Housing

    ADU is a great investment that opens access to many benefits and amenities. The completed project will provide qualitatively new living conditions for your family and contribute to the creation of a dream home. However, you will achieve such an effect only if will you interact with a professional team, and among all the contractors in California who do a high-quality job, the guys from A+ are the best.

  • Frequently Asked Questions

    What are the advantages of cooperation with custom home builders?

    Professional custom home builders know everything, even the smallest details of this business, which includes construction, architectural, and legal aspects. General contractors will protect your home from future breakdowns and household accidents, which are inevitable if an amateur takes over the implementation of the ADU project.

    How much does a new ADU cost in Placer County?

    It is very difficult to name the exact amount of construction cost taking into account the work of custom home builders. However, there are certain ranges. For example, a service to build a junior ADU will cost up to $80,000, an attached ADU will cost about $120,000, and a detached type we can estimate at about $180,000.

    What are the main pros of ADU construction?

    There is no need to search for the particular advantages of ADU since everything is on the surface. This type of additional construction on your site can significantly increase the value of the property; with its help, you can receive passive income, place relatives on the same territory with you, and just spend free time with your loved ones.
