      Our homes are like our little personal projects that can always reflect our current state of life, style preferences, creativity, and so on. Hence, there can never be too many improvements made to them!

      One of the changes that some of us will need to make at a certain time in life will be related to the increase in the amount of living space that we have. But what to do in case you cannot simply sell your current home and buy a new one? Build Accessory Dwelling Units (ADUs)! ADUs are a great solution to add extra living space to your property. If you’re considering building an ADU, it’s essential to work with an experienced ADU builder who can guide you through the process and ensure a successful outcome.

      ADU Builders Grass Valley, CA

      As Accessory Dwelling Units are considered to be tiny homes built on your property land, many homeowners think that it is easy to build them and that a simple Youtube tutorial could cover all the steps that need to be done.

      Unfortunately, this is not true. Yes, ADUs are much smaller than your primary house, but they still require all the same knowledge and skills in order to be built safely and beautifully, which is why you should hire professional home builders to do the project for you!

      That way, you can ensure that the whole project is done within the budget that you can afford, without any mistakes, and within a time frame that is as small as possible! Contact A+ today and find out more details about the project that could take place in Grass Valley or any other city!

      ADU Contractor Grass Valley, CA

      Now that you understand the importance of home builders in ADU projects, you can actually start looking for one. However, this is not a simple task, and you should take it seriously so that the new construction that would take place on your land would not bring any danger to your family.

      And in order for you to ease this burden, the following list was made so that you would find decent home builders in a much shorter period of time:

      1. Consider several contractors at once so that you can compare them to each other. That way, you will increase your chances of finding the perfect home builders for your granny flat, as well as ensure that the business company hired by you will do the whole job just as you want it! Check portfolios of other contractors before you make the call to the first company that you have liked;
      2. Home builders that you will hire should be extremely honest with you from the very start. You will trust your property and money to these people, which is why you have a right to know in advance about every type of solution and service that would be required for your project. A decent business company will always provide you with a free estimate of a project; remember that;
      3. Online reviews are a good thing that will give you a basic understanding of the home builders that you are going to deal with, but you will always benefit from digging a little bit deeper. Ask around your friends, relatives, and neighborhoods about their experience with their crew of general contractors so that they can give you good advice about the whole search process, as well as tell you about companies that should be avoided;
      4. Any contractor that you will consider should always have a valid license; this is a must! Without it, you can never be sure of the quality of services provided to you, as well as about the integrity of the business company that you are dealing with. A license is your guarantee that any granny flats built by this company will be safe for your family to dwell in for many years, so search for information about them very thoroughly!

      ADU Unit Construction Grass Valley

      Anyone who is new to the whole ADU construction process thinks that after the business company is chosen and the design is decided upon, the building process could take place on the construction site. However, this is not entirely true.

      Another crucial reason why you absolutely need to hire general contractors for your granny flats is the legal aspect of the whole process. ADU construction should always be made in sync with local jurisdiction regulations. And unfortunately for us, building codes are not universal for the entire country or even for one state law, which is why local contractors are a must so that your project would not be shut down the minute you send your documents for a building permit.

      There are parking requirements, minimum and maximum square foot sizes, and many other law regulations that you need to find and implement into your project, which is why hiring A+ Construction & Remodeling or any other builder would only benefit you!

      Benefits of ADU Building

      By now, you already know that building an ADU in California can bring you additional living space, as well as the possibility of receiving additional income. However, these are not the only benefits that you can obtain from your ADU in Grass Valley or any other location.

      Here is the list of some of them that are not as known by the public but still can be crucial to some of you:

      • During the time that the contractors will work on your construction site, your overall property land will be improved. It is common for new construction projects to require some preparation work to be made, such as land alignment, lawn improvement, and lots of other cosmetic shortcomings that your Grass Valley property might have. You might even ask for some landscaping services;
      • It is usually the case that when we finally understand that we need some additional living area for our family, we need to receive it quickly. Fortunately for you, ADUs are exactly the type of projects that would allow you to receive a fully completed new construction project after about six months from the start of the construction done by your helpful contractor, designer, and architect;
      • Even if you do not plan to rent out your ADU, you will still end up with a bigger property value once your backyard cottage is built. The more the square footage of your property, the bigger the payment that you could receive when selling your land;
      • In addition, as ADU are small in size and built on an already existing property land, they are much more environmentally friendly! ADUs leave a smaller carbon footprint, do not create a lot of industrial waste, and can be equipped with energy-efficient panels!

      An Accessory Dwelling Unit or an ADU is an independent dwelling that you can build on the same property land that you have right now. It is capable of providing you with the same amount of new living space as the new house would have, but you will not need to move to another area or spend an enormous amount of money on buying a bigger property!

      Hence, if you want to learn more about types of Accessory Dwelling Units and why one might need them, then we would suggest to keep on reading this article!

      ADU Contractor Building Types

      There are many different types of Accessory Dwelling Units that you can build in Grass Valley, California! And although this might mean that you would need to spend more time considering the options that you are provided with, this fact also allows you to find the most appropriate Accessory Dwelling Unit for the needs that you have, as well as spend just the right amount of money on its construction!

      Here are the most popular choices of Accessory Dwelling Units in California that you might want to consider building as well:

      • Junior ADU

      This is the smaller type of Accessory Dwelling Unit that you can create in Grass Valley or any other city, and it would involve a reconstruction of your already existing pieces of property, such as your basement or attic. Yes, it is not common for us to think of these places as the ones that could actually give us that little amount of additional space in the house, but it is possible when the project is done by a professional general contractor like A+ Construction & Remodeling!

      For instance, your basement could act as a perfect place to pursue some hobbies or spend some quality time with the family. You can turn it into a small gym, an art station, or even into a home cinema!

      • Attached ADU

      The attached ADU is definitely a much bigger area than the previous one, and it would not include a reconstruction of your already existing living area. The Attached Accessory Dwelling Units are independent dwellings that are built near your main residence and share one wall with it.

      Such projects are perfect for those people that do not really need their new living area to be a place where some loud extracurricular activities could be pursued. For instance, you should choose an Attached Accessory Dwelling Unit in case you simply need some additional space that would allow your kids to have separate rooms or for you to have a personal office.

      Yes, attached ADUs could also be used as a rental place, but they would not provide your tenants with much privacy and hence, would bring you a lower rental income.

      • Detached ADU

      A detached ADU is the biggest and most independent project that you can do in California. They will not share any walls with your primary home and will not be placed inside of it as well. Detached ADUs are also often called backyard cottages or granny flats.

      Such Accessory Dwelling Units would need to be built from scratch, from the foundation and plumbing placement to the wall paints and furniture orders. And because of that, a lot of mistakes will be made in case the construction is done by homeowners themselves.

      Hence, you would want the help of a general contractor for this job so that no mistakes would be made and the project would be finished within the shortest period of time possible! Contact A+ Construction & Remodeling today and learn more about your ADU possibilities in California with the budget that is available to you!

      Grass Valley ADU Construction Company

      Homeowners do not usually like collaborating with professional contractors, not only because they think that the job can be done without any help, but also because trusting your land, the house where your family lives, into the hands of unknown people is scary.

      ADU Building Grass Valley

      Aside from the most popular purpose of ADU to provide you with some additional living area, you can use this space for many different reasons throughout your life. In the summer, this little house can serve as a great place to rest near the pool, grill some veggies and play basketball with kids.

      During the work days, this place could play the role of your home office, which is something that many adults will appreciate after COVID. Think about it, no crying kids would disturb you there, no dogs would bark in the background, and no fighting teenagers would make you angry. And once your working days are over, you can easily remodel your ADU and create your own hobby corner where you can be as loud and artistic as you want to, and no one could say a word about it!

      Prefab ADU Construction

      Although you already know about attached, detached, and junior ADUs, there is still one kind of backyard cottage that we have not covered: prefab ADUs.

      Prefab ADUs are built not on your land directly but in a professional factory that specializes in ADU building processes. This option is perfect for those people who need to receive a new dwelling as fast as possible for a minimal price and do not care about custom design possibilities. There will be a list of options created by a designer for you to choose from, but you will not have a chance to add something of your own.

      Therefore, opt for a prefab ADU in case you don’t really care about the originality of its design and want to receive the result in the quickest manner! And fortunately for you, A+ Construction & Remodeling can provide you with this type of ADU as well!

      ADU Housing

      Once the ADU is built, you no longer need to feel doubts its usefulness to your family! It does not matter what your initial purpose for building an ADU was; you will always have a piece of property that can be as versatile as you need it to be!

      Hence, you will not only receive an increase in your property value, but you will also improve the quality of life that your family has!

    • Frequently Asked Questions

      How much does it cost to build ADU CA?

      The final cost of building an ADU on your property would depend on multiple criteria, such as the pricing of the company that you hired, the cost of the materials that you want to use, the size of a building that you will create, and so on. Custom design ADUs will always cost you more than prefab ADUs. But on average, you can expect your ADU to cost you around 300,000 dollars, so prepare a decent budget in advance!

      How much would it cost to build a garage with ADU on top?

      On average, an above-garage ADU costs homeowners about 200,000 dollars. But, of course, the final pricing would depend on the size of an ADU that you will create, the current condition of your garage, the materials that you would like to use, and the budget that you have.

      Is it worth it to build an ADU in California?

      Yes, it absolutely is! As we have mentioned in the article above, ADU is a versatile building that you can use for many different reasons throughout your life. It can be a helpful rental place, a cozy guest house for your friends and relatives, a comfortable home for the elderly, a personal office, or a simple pool house. You can even later remodel it into a place for you to pursue your hobbies!

      How long does it take to build an ADU in California?

      The building process itself usually does not take more than six months. However, aside from the construction period, there will also be the ones related to creating plans for your future home and receiving approval for those plans from your local authorities. Lots of things need to be taken care of for the project to be approved by the law; even parking requirements could be a problem!

      Our experience of building an ADU with A+ was fantastic from the initial design process to the construction itself. The crew was professional, and I loved watching each phase come together. When the ADU was finally complete, it felt and looked like it has always been there. Even our neighbors commented on how seamlessly it blends in with the main house, which was important to us.

      When I started looking for someone to build our ADU, it was tough to choose until I met with Oleg from A+ Construction. From the start he made me feel comfortable and sure I made the right choice. The work was excellent, 10 out of 10! The workers were skilled and easy-going. After they finished our ADU, my in-laws decided to have them start on a project at their house too.
