    Each homeowner tries in various ways to improve the living space by all available methods, including hiring an ADU builder Sacramento. Some solutions can add beauty to the house, others functionality; however, there is one way that allows you to achieve all your goals at once, namely the construction of an accessory dwelling unit.

    ADU Builders Alta, CA

    If you decide to build an ADU, then you will need the professional services of a general contractor, and here are two main reasons why. Firstly, the contractor team consists of highly professional specialists (designer,
    architect, builder, electrician, etc.), each of whom perfectly knows the nuances of the job. This will help to avoid mistakes that may complicate the life of the homeowner in the future.

    Secondly, the company’s employees know important insights, for example, permitted construction standards in a certain city in California, where it is more profitable to purchase materials and much more. This significantly
    saves the strength, nerves, and money of the homeowner.

    ADU Contractor Alta, CA

    Finding the perfect general contractor who can complete the ADU construction at a high level is not an easy task, especially if it happens for the first time in your life. However, there is a set of parameters, and knowing
    which it is much easier to pick a company that will build an accessory dwelling unit for you.

    We identify three basic factors that will help you with the choice:

    1. Relevant experience. A large number of completed construction projects is the strength of any contractor. However, among this number, there should be works corresponding to your expectations about the future ADU. That is, if
      you are planning to implement an attached ADU project, then the construction team should have such experience in the portfolio.
    2. Availability of an official permit. The activities of each contractor must be authorized and permitted by all local laws. Such permission is provided in the format of a construction license, so be sure to check its
      availability and expiration date.
    3. Reputation among the population. For any ADU contractor, there is no greater praise than a high rating from the community of homeowners. You can do a little research in your neighborhoods and ask people about the quality of
      the service that the company provides.

    All in all, typically, these three points are enough to weed out most contractors and abandon their services. Some companies can only meet two positions out of three. However, there is a firm in Alta city that meets all three
    requirements, and this is A+ Construction & Remodeling.

    ADU is an autonomous residential space that can perform many functions, increase the value of your property and even permit you to earn money, thereby paying off construction costs faster. On par with this, it is an
    aesthetically stylish and environmentally friendly building.

    In this review, we will tell you what types of accessory dwelling units exist, what factors need to be taken into account if you are planning to build an ADU, and which general contractor in Placer County will cope with this
    task best.

    ADU Contractor Building Types

    There are a huge number of ADU types that you can place on the same territory as the main property. Each accessory dwelling unit is distinguished by its unique layout, price, functionality, and a set of advantages.

    • Detached ADU

    This is the small self-contained building that is located separately from the primary residence. The detached unit is equipped with all rooms for comfortable living, in particular, a bathroom, kitchen, and a spacious sleeping
    place. If desired, you can transform a one-story ADU into a two-story one, add an attic, and also rent this space.

    • Attached ADU

    The key feature of this project is that the new building has at least one or even several common walls with the main house. The same can be said about the foundation. These factors influence the fact that the construction
    process of attached ADUs is relatively short. You can use this space as you want; for example, you can make a home office, create a home theater or add an extra bedroom if your children have grown up and they need separate

    • Garage Conversion

    The condition of the existing garage among the majority of homeowners is quite depressing because this space is rarely used effectively. With the help of the garage conversion project, you can solve this topical problem. For
    example, create a small workshop if you like a car, a place for children’s hobbies and games, or a space for relaxation and yoga classes. Finally, the converted garage can be equipped in the format of a place where a family
