    ADUs, or accessory dwelling units, have become one of the most popular project types for which general contractors are hired. And honestly, this is not a big surprise because the amount of benefits and functionality that an ADU can bring to a homeowner is truly astonishing. Nowadays, it is possible to create any kind of ADU in Sacramento, CA.

    With a small accessory dwelling unit on your property, you get not only extended living space, but also a guest house or a new home to rent out and receive some additional income. The great thing is that you can create a quality ADU with any kind of budget, and A+ Construction & Remodeling team is more than ready to help you with this task. Explore the possibilities of ADU homes Sacramento and transform your property into a versatile and valuable space.

    ADU Builders Sacramento, CA

    Building accessory dwelling units from scratch is not an easy task, and someone with no professional experience can come across a lot of obstacles while trying to do that. A general contractor can be of great help in such a situation. Still not sure whether California ADU builders are worth your time and money? Look at some possible advantages that will make your business-making with contractors a must.

    First of all, the whole process doesn’t take a couple of days, and you would have to dedicate a lot of time to the process. Not everyone’s job allows this, and combining both work and building an ADU can be really exhausting. Moreover, you have to spend some time with your family as well, which would be hard if there was construction going on.

    Second of all, if you have no expertise or experience in such projects, you will probably face some mistakes and failed attempts. They can cost not only your time and patience but also money. Once the project is complete, you might spend twice as much as you would’ve spent on hiring general contractors.

    Third of all, when you are not hiring a builder team, you will probably have to search for different specialists separately. This takes a lot of time, and you can never be sure when a particular part of the project will be completed so that the next one can start. Also, the quality of the job done is not guaranteed in all cases.

    Thus, hiring ADU builders in Sacramento, CA, is the only rational solution when you want to spend your time and money wisely. A+ Construction & Remodeling has professional teams all over California, and we will get your project completed according to the stated budget and in a timely manner.

    ADU Contractor Building Types

    Before you decide to start the entire process of constructing an ADU, you should first decide what kind of secondary unit you would like to have. There are no essential rules for this that all homeowners should follow. For an ADU project, the size of your lot, proximity to the primary residence, and personal preferences should be considered.

    Here are the main types of accessory dwelling units that you can create using A+ professional contractor services:

    Detached ADU

    A detached accessory dwelling unit is a new construction on your lot that stands separately from the main home. It can be located anywhere in your backyard if it is allowed by the zoning regulations. A detached ADU usually has its own entrance and can serve as a whole new house, just of a smaller size.

    Attached ADU

    The attached accessory dwelling units help you to have your primary residence extended without disturbing the privacy of family members. Such projects usually have at least one common wall with the main dwelling, and they might also share a bathroom.

    Junior ADU

    Junior ADUs, also called JADUs, are smaller constructions that serve as an extension of your home. You can make your kitchen area bigger or add a new dining area to the existing space without remodeling a big part of your house.

    Garage Conversion ADU

    Garage conversions are another popular variety of ADUs. You can completely remodel your own garage and turn it into an accessory dwelling unit. This allows you to save space on the property and add more functionality to an unused space.

    Whatever kind of ADU project you choose to have, A+ has some of the best contractors in Sacramento County. With professional services available in all the popular locations, as well as smaller areas, our team will provide you with everything from preliminary planning to the final steps of construction.

    ADU Unit Construction Sacramento

    The entire project of creating an ADU consists of several steps, each of which is coordinated by the A+ team. To have a clearer idea of what it’s like working on a building project with contractors, we recommend you read through the complete list of all the stages of creating a new construction.

    Accessory dwelling units go through the following steps of development:

    1. You have the first meeting with A+ office staff, discuss your ideas, and get the estimate for the budget;
    2. Designers work on the appearance of the future ADU, including the interior and exterior;
    3. Professional architects make plans according to all the state and local law regulations;
    4. The project goes under review by Sacramento officials, and if all the requirements are followed, the building permit is received;
    5. The construction or renovation of the existing space is done, according to all the plans.

    Although it might sound simple, there are many specificities of the project process that have to be taken into account. In order to do everything in the correct way, contact A+ to work on your ADU in Sacramento county.

    Benefits of ADU Building

    When you get your ADU built properly, you and your family get to enjoy plenty of benefits that these units bring. And improvement of the existing space that has been out of use is only one of them.

    Here are some other advantages of building accessory dwelling units:

    • You get more living space. Whether you would like to turn your ADU into a guest house or a granny flat, an ADU is a perfect structure for this, as it’s not as costly as building or buying another house, and it doesn’t take up much space on your lot.
    • An ADU can be your source of passive income. If your family wants to increase its budget, a secondary unit gives a perfect opportunity for this. Receiving rental income from a small home in your backyard is quite easy, as you also get to look after your ADU so that nothing bad happens.
    • If you are doing some business from home, your own property can become your office. Simply transform your secondary dwelling unit into a working space or a studio, and get a nice environment to concentrate on the important things without getting out into the city.
    • In California, it is pretty popular to turn your ADUs into a home cinema or home gym. Thus, you can enjoy spending time with your friends and family or working out right on your property.
    • If your family has grown bigger over the years, you can extend the main dwelling and turn it into a living place with its own utilities. The comfort of free space and the right amount of privacy will make the life of any family better.
    • Accessory dwelling units are also great for your property value. If you ever decide to sell the main house, the value of your property on the market will be bigger thanks to this small addition.

    Want to make the best out of your new construction? Have professional contractors build everything according to your needs and wishes, and enjoy the new space over the years to come.

    ADU Building Sacramento

    Creating an ADU includes not only the construction process itself but also complying with various law regulations imposed by the city, state, and country. Local rules may vary from one place to another, and that is why knowing all the specificities is important.

    Take a look at some of the legal requirements that have to be followed:

    1. The number of ADUs allowed per single-family property is two, and for multifamily homes, it is one per every four homes.
    2. The number of square feet cannot exceed 1,200 for all the ADUs combined.
    3. Attached ADUs can be no bigger than half of the main home’s area;
    4. One-story ADUs are required to have 60 feet setbacks from the front line of the property, while two-story units must be at least 4 feet away from the side and rear lines.
    5. As for fire safety, fire sprinklers should be added if the primary unit has them.
    6. ADUs allowed to be built on any property size must not exceed 16 feet in height.

    An ADU plan that does not comply with these and some other regulations will not be approved by the local officials for the permit, and you will have to pay for another application once it is corrected. To avoid wasting your time and budget, it is better to hire contractors with professional legal staff, such as the ones at A+.

    We carefully review each plan at the stages of development to make sure that everything is done in the correct way. Thus, you won’t have to study the numerous laws by yourself or look for a specialist separately. Such a way of building an ADU in Sacramento is more comfortable and convenient for any property owner.

    Prefab ADU Construction

    If you are not looking forward to a long construction process going on in your backyard, there is an easy solution. A+ offers prefab ADUs to its customers. Prefabricated units are created part by part in advance, and then they get delivered to your lot for quick assembly.

    Thus, you will get all the walls, roof, windows, and other essential parts delivered in different pieces, and then our business will work on creating a proper ADU out of it. Such an option is an affordable one and requires much less work than building an ADU from scratch.
