    Our life doesn’t stay still for a moment. We grow older, find hobbies, our kids become adults, and our parents get old. All these things need free space, preferably close to us. The question arises, how do you find a cheap property that could be built next to your house?

    Thankfully, the world of construction options needs to be made better and always evolves. The recent trend in this sphere is the construction of prefab ADUs. The prefab accessory dwelling units, which are sometimes called granny flats, backyard cottages, or custom houses, represent a small building with all the necessary amenities that are situated on your lot next to the main house.

    ADU Builders Penryn, CA

    Normally, any owner is expected to be knowledgeable in the matters connected with home repairs and small renovations. However, ADU projects are more complex than they seem because the whole process includes a variety of different tasks which are hard to do on your own. For sure, you can start the ADU construction, but no matter how hard-working you are, we estimate that you will spend twice or thrice as much time as a hired team of home builders would have spent.

    All in all, it is relatively easy to find a professional team of home builders who will do the construction as well as take care of legal issues like building codes in a census-designated place like Penryn. Take into consideration the points below.

    ADU Contractor Penryn, CA

    The quality of the new construction almost entirely depends on the choice of the company that will provide you with services. However, when it comes to choosing a business that will take care of your project, there are all sorts of intricacies to take into consideration.

    A+ Remodeling & Construction, whose professional team with years of experience and numerous finished projects of high quality, is the best pick for this task, and here is why:

    1. Portfolio of completed projects

    The quality job should speak for itself; hence, on our site, you can find the projects completed by us. Based on our previous works, you can decide for yourself whether our designs match your vision of the future ADU or not.

    1. Budget

    When homeowners hire contractors, they have already decided to spend a certain sum. Before making a choice, we advise you to call the managers or look through the site and check the cost of completed ADUs. Remember that building a granny flat is not cheap, so the price must be respective, which is clearly seen from the projects done by our crew.

    1. Licenses

    Honest builders have nothing to hide. Hence, they normally provide customers with all the documents that are necessary to build accessory dwelling units. On our site, you can find information on the matter in a special section.

    Read this article further to find out more about ADUs. However, if you are already interested in constructing one on your property, contact the general contractor A+ Remodeling & Construction. They can do an excellent job at quality levels never to have been seen in any part of Placer County.

    ADU Contractor Building Types

    The preferences of clients concerning the ADU building project are always different. Hence, contractors have come up with certain variations of ADUs that are different in price, proximity to the main house, time spent to complete the project, and so on.

    On your lot, we can create the following ADUs:

    • Attached ADU

    Even though this is a totally new construction that will be built on your property, one wall will still be connected to your main building. Because of it, the cost of such construction is lower than that of detached ADUs while saving all the benefits.

    • Detached ADU

    Detached ADUs are great for people with a big budget and much space on the lot. Our home builders will create a new independent structure on your lot with its own entrance and the necessary amenities. This new home will not be connected to your main house in any way, so it fits well to generate rental income.

    • Conversion

    In case you choose the conversion, we will not have to construct anything new on your lot, but instead, we will do a renovation of the already existing space. For example, in our portfolio, you can find cases when we succeeded in transforming the existing garage into a modern ADU with all the utilities.

    • Junior ADU

    The main distinctive feature of JADUs is their size. The completed project has to be smaller than 500 square feet. This type has looser rules for building codes which lets home builders be more creative in the process.

    ADU Unit Construction Penryn

    The construction of an accessory dwelling unit requires following the laws and regulations imposed by the government and the state of California. First, on your lot, there has to be the main house. The future ADU will be smaller than it. What is more, it has to be built by the owner of the main property.

    Second, there are regulations that impose the dimensions cap. 500 square feet is the maximum for a JADU, while 1000 square feet cannot be exceeded by a regular ADU. Moreover, the attached ADU, no matter the number of floors, cannot be higher than 30 feet. As for detached ADUs, the number is twice as small, 16 feet only.

    Benefits of ADU Building

    ADUs can be easily named an indispensable part of any modern house in California, and here is why:

    • ADUs allow you to get extra income by doing various actions. You can rent your amazing ADU to the tenants or even sell the whole lot with an ADU that increases the total value of the property. Hence, ADU construction can become a key element of your new business.
    • None of us is getting younger, and perhaps the time has come for your parents or grandparents to move closer to you. You can set up a perfect space for their life nearby by building a unit with all the utilities, including a bathroom, kitchen, toilet, and everything else.
    • Tired of numerous guests coming to your home from all over California? In this matter, ADUs can be a helpful solution. For guests from Elk Grove, Citrus Heights, or even Granite Bay, who want to stay overnight, an ADU with a bathroom and bedroom will be more than they need for a comfortable rest.

    Penryn ADU Construction Company

    There are numerous ways one can influence ADU construction:

    1. Before agreeing on the design and the first payment, we offer a free consultation to our customers. There you can express your ideas concerning your ADU, talk about your expectations from the finished project, and we will figure out the best solution for you together.
    2. A responsive person involved in the process of construction is the best client. If you see that something goes wrong during the construction of an ADU, tell our home builders or managers as fast as possible. This can help us avoid possible blunders that occur now and then and, in the end, leave you satisfied.
    3. Having agreed on the design, there is little we can do to alter it. However, if you have decided on, for example, replacing the material for your roof with better ones, we can do something for you.

    ADU Building Penryn

    As we have discussed earlier, there are many ways one can use an ADU. However, there is also a grand variety of options for how it can be transformed.

    If you need more space for your hobby, for example, photography, and want to avoid finding an office, use your ADU. Install the necessary lighting, buy cameras, and start your hobby. What is more, you can increase the attraction of possible tenants through the distinctive features of your ADU. Hardly can one resist renting a place with two bathrooms or a spa.

    Add these features to the design of your ADU, and we will do our best to bring them to life. Building accessory dwelling units has always been challenging with A+, one of the best general contractors in California!

    Prefab ADU Construction

    Even though we have discussed ADU variations earlier, there is one option we should have mentioned. Prefab ADUs stand apart from other types while having distinctive features, too, the most important one being their prefabricated nature. Yes, we will not create the design from scratch specifically for you but rather offer you to build one from our portfolio. Your ADU will not be original, but, for sure, our services will cost you much less. Moreover, the time spent to build one decreases dramatically too.

    So, opt for a prefab ADU if you are looking for a fast and rather inexpensive option. Contact A+, and we will find the best prefab ADUs just for you.
