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
rooms.

  • 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
archive, garden tools, and various types of transport (scooter, bicycle, scooter, or monowheel) will be stored neatly and not in a mess.

  • Basement Conversion

One of the most difficult projects in terms of implementation. The timeline of work can reach several months because it is necessary to completely transform the space from floor to ceiling. However, the result will be fantastic
and will exceed all your expectations. A new room can become a cool place to relax; you can equip it for an elite wine cellar, a home gym, or a library.

Overall, each of these projects can increase the value of the property, bring a lot of practical privileges and make living conditions more comfortable. However, for this to happen, you need to find a highly qualified
contractor who can complete the job at 10 out of 10. This will be discussed further.

ADU Unit Construction Alta

Another important reason that will motivate you to interact with a general contractor is the legal aspect of ADU construction. The laws about the placement of ADU on a residential plot vary depending on the location of the
residence. For example, the construction requirements in Alta city may differ from other towns in Placer County.

Let’s look at the concrete example of garage conversion. If you are planning to implement such a project, then you need to know the minimum lot size, the maximum lot size, the required parking dimensions, ceiling height,
and the approval timeline. Please note that you also need to take into account the zoning laws of garage conversion.

In this regard, the team of every professional contractor should have a world-class lawyer, and in A+ Construction & Remodeling, such specialists exist. They know all the building codes of all cities in California and will
help you get the necessary building permits asap.

Benefits of ADU Building

The main advantage of ADU is the guaranteed return on investment that you spend on the construction process. However, the list of benefits that the homeowner will receive does not end there.

We identify five main positive factors from the implementation of the ADU remodel project:

  1. Additional income. Installation of ADU permits you to receive passive income without making an effort since you can rent out the premises. An additional advantage of this solution is that the ADU will be in operation and not
    stand and gather dust without application.
  2. Organization of large family events. Very often, we have the desire to join all family members together in one place, but there is no such opportunity. Fortunately, ADU easily solves this problem because you will have an
    additional kitchen, bathroom, and several beds for convenient accommodation for guests.
  3. Home theater. Perhaps this is the biggest dream of every homeowner because watching a movie on the big screen gives a lot of positive impressions, charges life energy, and unites the family. In the first stages of the
    implementation of the ADU project, you can ask architects to create a design for a home theater.
  4. Sports activities. Regular exercise is very good for health, but a working person does not have the opportunity to go to the gym every day, as it is very expensive and not practical. ADU construction will allow you to be
    engaged in physical activity every day because you can make a home gym out of the available space and install all the basic equipment.
  5. Child development. The new building on your site can be used to broaden the horizons and develop the skills of the child. For example, you can organize an art studio, a children’s room or install a Swedish wall on which
    kids can splash out energy and spend time with friends.

On the whole, you can start using these privileges immediately after the construction is completed. However, to remain fully satisfied with the finished project, it is necessary to hire a highly qualified developer, and in Alta
city, this is the A+ team.

Alta ADU Construction Company

Typically, almost every ADU contractor removes the client from the construction process; however, this is the wrong decision because the homeowner has the right to keep direct contact with the developer throughout the entire
working period.

In this regard, A+ Construction & Remodeling is an exception:

  • Productive first consultation. Already at the first meeting, you will have the opportunity to discuss the main points of construction, in particular, the budget, work timeline, room design, and much more. You will also
    receive valuable tips, for example, how to save budget by purchasing cheaper, but no less high-quality, materials.
  • Making adjustments. If you are planning to make changes right during the workflow, then you can always perform it. To do this, it is enough to discuss an idea or proposal with the project manager.
  • Interaction with team members. At each stage of the building process, the homeowner needs to make important decisions, for example, pick the type of flooring or select the most suitable wood for the door. In order not to
    make a mistake, you can consult directly with each of the specialists, e.g., architects, designers, or electricians.

In total, only responsive staff work at A+; they try to make every effort to build the perfect ADU for you and comply with all your wishes. In this aspect, there is no better company in Alta city, so contact our managers to
discuss all the details.

ADU Building Alta

The advantage of ADU is that this building has several hidden features, the existence of which some homeowners do not suspect. Most of them are related to the way ADU is used. For example, one of the options for a garage
conversion is a man cave. This is a space in which you can install a billiard table, a console with games, a home bar, and table football, and choose the most brutal and masculine design.

Another unusual variant of ADU is a pool house. From the name, you can guess that a pool bowl is installed in front of the building, as well as a place for a grill and a basketball court. Finally, ADU can be used as a coworking
space if you work remotely. You can put a sofa, a coffee machine, and a board for brainstorming. This will allow you to immerse yourself in thoughts and distract from the hustle and shouts of children.

Prefab ADU Construction

The development of the construction industry has reached such a stage that now it is not necessary to contact an architect or designer for their services. You can order a finished building, and the manufacturer will deliver it
to your site in the format of panels or modules. All issues related to logistics are also taken over by the contractor.

Such projects are called prefab ADUs, and their main advantage is a short installation period and low costs. The most popular option is Junior ADU; these are single-family homes with a small area, and the construction of which
takes no more than two months.

As in the case with any other ADU types, do not forget to study building codes because there is a separate law for prefab houses.

ADU Housing

The decision to build an ADU can be fateful for you, incredibly profitable, and of high quality in terms of improving the level of living conditions. However, to get the perfect ADU, you need a responsive and professional
contractor. The name of such a company is A+ Construction & Remodeling, which provides the best building services in Placer, California.

  • Frequently Asked Questions

    How much does a new ADU cost in Alta city?

    The cost of construction services depends, firstly, on the size of the ADU and, secondly, on the contractor because each company sets its price tag. We can say that the cheapest option is junior ADU because of the small area,
    and a detached unit will require the most investment because it is a separate building.

    What is the timeline for the ADU project implementation?

    It is also impossible to give an accurate answer here. For example, prefab ADUs are the fastest option because, in the shortest possible time, the contractor will deliver the modules to your site and assemble the structure in
    less than two months. The longest option is large-scale projects, for example, two-story ADU, as you can start discussing the layout and design in January and finish by the end of summer.

    What are the advantages of ADU in Placer, California?

    If you decide to build an additional dwelling unit, then this will at least permit you to increase the value of your property, receive passive income and improve living conditions. Also, since ADUs are energy efficient, your
    utility costs will decrease, and there will be a place for the storage of various things and relaxing.
