    The world of construction doesn’t stand still, and right now is moving forward at a tremendous tempo with more advanced technologies used in the process of building as well as a variety of remodeling and creation of new units available to customers. Truly, it’s hard to find home builders who wouldn’t provide homeowners with a bright palette of different constructions that are bound to satisfy the pickiest customers. However, the most popular option remains to build an ADU.

    What, you don’t know what an ADU is? It’s never too late to learn something new. ADUs, which are sometimes called granny flats, backyard cottages, or bonus homes, represent a construction built on the lot with the main house. An enormous number of general contractors and Sacramento ADU builders offer their services concerning the building of an accessory dwelling unit in California. Before you start contemplating different options on how to use this free space, let us tell you more about these units.

    ADU Builders Walnut Grove, CA

    If you have tried to install a new roof, do a kitchen remodel, or paint walls, you understand how much preparation, force, and money are needed to turn ideas into reality. And these are just rather simple projects.

    Even though many people falsely think that constructing an ADU is a no-brainer, in reality, this process includes various skills and lots of knowledge. Yes, an accessory dwelling unit is much smaller than building a new house; however, it is not that easier to build one. In this case, a crew of professional builders has to be hired in order to maintain the good quality of the final product.

    Contractors working in California, especially in Walnut Grove, can get the job done quickly and with great quality. Contact A+ Construction & Remodeling today and give rise to a new project starring your property.

    ADU Contractor Walnut Grove, CA

    You may be asking yourself a question – what to pay attention to if I start looking for a general contractor? Just like theater begins with a hanger, an ADU begins with a general contractor. Let us figure out once and for all the characteristics of a reliable ADU contractor.

    We have amassed lots of experience throughout the years of work in this field and want to share with you how to find the right home builders for your project:

    1. Pay attention not only to the reviews on the Internet but a variety of different factors. For example, ask around the city whether anyone knows anything about the general contractor you are considering or find people who have already worked with them. Normally, people’s experience can give you much more info about the service and the quality of installed ADUs.
    2. Necessary documents are also an important moment during the search for the general contractor. The home builders you hire will have to deal with all sorts of laws and regulations imposed by the government, and it would be quite hypocritical if these home builders themselves don’t have necessary permits confirming their right to build ADU.
    3. The construction of an accessory dwelling unit is a task that consumes time as well as money. Visit the site of the possible general contractor and find their price list. If you notice something unusual, for example, the extremely low prices for an ADU, we wouldn’t recommend you work with such home builders as there is a chance that they will simply take your money and disappear with them.

    If you are interested in building an ADU, the sooner you start looking for a general contractor, the better. Having years of construction experience A+ Construction & Remodeling company can offer you the creation of an accessory dwelling unit for a rather small price and of great quality. Contact us now!

    ADU Contractor Building Types

    So, you’ve decided to build an ADU – but which one? Do you know that in recent years contractors have come up with a variety of ADU types, and each one has its distinctive features? Before commencing new construction, you have to decide on what backyard cottage you would like to see on your lot.

    Our company offers to build the following ADU types:

    Attached ADU

    Looking at the finished projects, it is easy to notice the distinctive feature of it – a shared wall. Yes, this unit will be placed on your ground next to the main house, which it will have a common wall with. This decreases the time for the installation and lowers the budget requirements. Even though it is placed right next to the house, it will have a separate entrance.

    Detached ADU

    This type definitely comes to your mind when you only think about these home additions. It represents a new construction built on your lot that stands at a distance from the main house. While being the most expensive option on the list, it provides owners with much more privacy than other variants, as none will disturb the tenants there because of the personal entrance. What is more, you can choose the design according to your preferences, and it does not necessarily have to match the main building. You can change any materials for it, for example, siding, and add any custom detail you desire.


    If you have any unused rooms in your house, this option is for you. Consider ordering the conversion to turn your old and weary room into a fine living space that will attract tenants. As we will not have to build any new constructions, the cost of the project will not be huge. On request, our crew can replace the windows there or repair furniture. For your safety, access to the room will be closed for the time of remodeling.

    Junior ADU

    From the name, one can guess that this accessory dwelling unit will be smaller in size than other types, and they will be correct. The main requirement to build this ADU is the size, as it cannot exceed 500 square feet. Despite the size, we assure you that our crew can make you impressed by the quality of work they can do in these restrictions.

    ADU Unit Construction Walnut Grove

    In the previous paragraph, we mentioned the regulations for the ADU building in Walnut Grove. Well, these restrictions work in any part of California, so it’s advisable that you know them.

    Your general contractor should follow these regulations:

    • ADUs cannot exceed 1000 square feet if you build a regular one. As for Junior ADUs, the number is 500 square feet. What is more, an attached accessory dwelling unit cannot be higher than 30 feet (as for detached units, the number is also smaller – 16 feet).
    • Every accessory dwelling unit should be equipped with all the necessary utilities and have a bathroom, a bedroom, and a kitchen area. Moreover, there has to be a separate entrance.
    • The local zoning office should answer all your questions concerning the zoning regulations. Normally, ADUs are subject to strict regulations, so such consultations are highly advisable.

    Benefits of ADU Building

    Every owner has to have some courage to begin the construction of an accessory dwelling unit. Probably, the list below can help you make the right decision. Believe us, your family will not be disappointed with your decision to have an accessory dwelling unit on your land.

    The benefits of building an ADU on your lot are:

    1. Space for unexpected guests. If you have visitors from, let’s say, Walnut Creek, who like to visit you without notice, you may have encountered the lack of necessary beds and rooms to accommodate your friends and family with all due respect. An ADU can become an elegant and logical decision for this problem. They will also have access to the bathroom and maintain a certain level of privacy via a separate entrance.
    2. Space for the parents. You want to keep your family close, but your wife is against this? An accessory dwelling unit can become a new home for your parents. This will allow you to keep them close and take care if needed. Leave the family quarrels in the past and order an ADU.
    3. Space for tenants. A new home can increase your family budget if you start a renting business. You can rent your property to anyone you want. Smart design decisions, like siding or an extra bathroom, provided by our company can help you search for clients in Walnut Grove, Walnut Creek, or maybe even in Sacramento.

    Walnut Grove ADU Construction Company

    Working with a general contractor for the first time may be rather scary. You don’t confide the process of the construction of a house to other people every day. However, we may assure you that the years of tireless work on ADU projects have helped us realize more and more fascinating projects that we are proud of.

    However, our company has a grand variety of other advantages, such as:

    • Free Estimate

    Before signing a contract for ADU construction, you will get a free estimate from our employees. There you will see the approximate cost, time until the completed project, and other details.

    • Vast portfolio

    We have completed numerous projects in different cities of California, from Walnut Creek to Sacramento, so in our portfolio, you can find a project for your taste and budget, including remodeling options as well as the construction of totally new units.

    • Feedback

    We believe that the best owner is the one who is truly interested in their property and wants to have the best of the best. Hence, if you see that something goes wrong during the construction or want to add certain custom details, address any builder you see on the site, and they will pass your thoughts to the employees, and we will think about what we can do together.

    Home builders at A+ will be happy to provide you with an ADU construction. Having worked everywhere, from Walnut Creek to Sacramento, our services always satisfy the pickiest customers.

    ADU Building Walnut Grove

    We have already discussed the ADU types and their advantages, but you are still insecure about whether you want one? Overall, it will not be superfluous, but if you want some certainty, here are the ways one can use an ADU.

    Increased property value

    Every professional will tell you that housing prices always rise, sometimes faster and sometimes slower, but they never stop. Hence, having a custom home on the lot will allow you to find tenants who will pay you. It will help you pay it off and find money to repair your main house. Moreover, if you decide to sell your property, an ADU will help you ask for a better price.

    Space for hobbies

    In the completed ADU, you will be able to do whatever you want, for example, start a new hobby. A custom home can be transformed into your personal studio where you can start shooting your video blog and show the subscribers how to do bathroom or kitchen remodel. With a custom home, your possibilities are unlimited!

    Summer house

    An ADU can become a great place for meditation in the summer after all the stress throughout the year. Close all the windows to abstain from the outside world, stay in the bathroom as much as possible, create business plans, or focus on improving your competencies connected with the job. An accessory dwelling unit can help you do it with ease.

    Prefab ADU Construction

    If you don’t feel like ordering an accessory dwelling unit right now, consider installing a Prefab ADU. As you can tell from the name, this unit will not be as custom as the regular one, so you won’t have designers involved in this project, and it will be impossible to change anything about it, for example, add siding or an extra bathroom.

    Instead, we will provide you with an ADU design from our catalog. Our job will not require creating a new custom ADU design and working out special certifications. Consequently, the cost of the service will be much lower, and it will take home builders less time to complete the project. Time from breaking ground to delivering the finished accessory dwelling unit can decrease up to two times.

  • Frequently Asked Questions

    How long does it take to build an ADU?

    Overall, the amount of time required for professional home builders to complete the project depends on a variety of factors, including the location, building materials, foundation type, and many more. Surely, it will not take more than a year, as it did a couple years ago, but we estimate an ADU to be completed in a bit more than half a year.

    Can I make any changes to my ADU?

    After the job is done, our home builders will leave your new property in Walnut Grove, and you will be able to do with it anything you want, from custom siding to full kitchen remodel. We, as a general contractor, cannot interfere with any changes you find necessary in the finished project.

    What are the tasks of your home builders?

    Our crew of home builders has to work on the project from the start till the moment when it’s finished. We don’t reach out to any subcontractors and do all the work on our own. Our home builders have years of experience in building custom homes, so you can be sure that your ADU will be built according to modern standards and on time.
