    Have you ever heard of ADU? If not, then you are missing out on a lot. Along with other trending solutions for the repair or reconstruction of your primary home, ADU is a great classic way to make your home better and more functional. Often we do not have enough space in the house for storage, comfortable accommodation for friends or relatives who often come to stay, a playroom for children, an office, or a room for our hobbies. Perhaps you are planning to renovate your house in order to then sell it for a higher price. For all the cases listed above, there is only one ideal solution – the expansion of the existing space.

    However, how is it possible to do this so as not to violate the law and formalize a new extension as part of an existing house? ADU construction is a budget home solution that can be implemented quickly. ADU does not contradict state law but solves many problems that any property owner can face.

    Usually, an ADU is a separate house of a small size, which has everything you need for a full-fledged stay without the need to visit another house. ADU (also known as granny flats) has its own kitchen and bathroom, while this construction is located next to your primary home (a detached ADU) or can be an extension to it (an attached ADU) on the same land that you own.

    Large families with limited living space or property owners who are willing to increase a rental income will certainly be interested in this affordable housing idea.

    Roseville ADU Builders

    Have you already made a decision to build accessory dwelling units for your family or so that an accessory dwelling unit can be rented by another family? Great solution! Believe us, the time and money invested in this construction will not be wasted. At the initial stage, the main thing you should focus on is choosing a construction company and planning a future ADU project.

    If you choose the right company for building an accessory dwelling unit, then the builders will build an ADU and complete the work quickly and efficiently. A great option in Roseville, Placer County, is the A+ company. In general, the A+ company provides a wide range of services, including:

    • tile and plumbing replacement;
    • bathroom repair;
    • kitchen repair;
    • renovation of the whole house;
    • renovation or complete replacement of old furniture.

    Moreover, you can contact the specialists of the A+ company in order to build any type of accessory dwelling unit. There are four types of ADUs in total:

    • Separate ADUs that are built at some distance from the first house but on the same lot. A family member, friends, or adult children can live in detached ADUs;
    • Attached ADUS can be used for the same purposes, but these buildings are extensions to your house, so greater proximity is provided between the residents of the two houses;
    • Conversion to create a new living space is also a popular option when it comes to ADUs: this includes garage conversions, converted rooms that are separated from the rest of the house, and sheds;
    • Junior ADU is not a separate building, but only a certain part of an existing house with one or more rooms, but there may not be a separate bathroom, so two families essentially live together since they use the same bathroom or kitchen.

    We draw your attention to the fact that the builders of A+ are professionals and can perform any project listed above, no matter how complex it is.

    ADU contractor in Roseville

    Why would you need to contact a construction company in Placer County? A good company that employs professionals serves customers in order to facilitate the process. Generally speaking, the company shifts all procedures included in the ADU project from the client to its employees and, thus, is responsible for the whole process and selection of materials. Therefore, you only have to monitor the process from time to time and wait for the result. You will be surprised how fast and easily a new building can be added to the existing structure.

    What is included in the services provided by A+ in Placer County?

    • Consultation with managers that can now be held online (discussion of the type of accessory dwelling unit that you want to build in addition to your residential property, discussion of the budget, resources that need to be used to complete the building of an accessory dwelling unit and for it to be added to the same property without having problems with the state law);
    • Work of the designer or architect, development of the ADU project;
    • Procurement of materials;
    • Work of builders and designers to create a plan for a future converted property;
    • Delivery of materials to the plot.

    ADU Unit Construction Roseville

    Accessory dwelling units are a great way of having a new space for relatives or friends in Placer County, California. There are only a few building permits for detached ADUs. You can build a secondary dwelling unit for any family member to be comfortable and secure in the in-law units. In Roseville, there are all ADUs allowed. You might want to build detached, attached, converted, and junior ADUs.

    Roseville ADU construction company

    Another point that must be taken into account before the construction of the ADU is the legal side of the issue. Is it legal to build accessory dwelling units on a plot or rent out part of your house? Will you need to pay any fees for a new building as a new property? How to issue all the papers and permits on time? On all these issues, you will be able to consult with specialists who work in the A+ company (a manager and an experienced architect will provide you with all the needed info and resources for you to feel secure). Here are just a few basic requirements that you should be warned about in advance:

    Requirements for a plot

    At least one residential building must be located on your plot, and also, this plot itself must be of the type on which the construction of the residential property is allowed, whether it is an ordinary house or an accessory dwelling unit. Talk with a lawyer in advance if you do not know what type of land you own belongs to.

    Limit on the number of buildings

    According to the law, the number of ADUs that you can build on one piece of land is strictly limited. For one family that owns one house, the construction of a maximum of two detached or junior ADUS is allowed. A larger amount of ADUs can be allowed only in cases of construction on a plot where there is an apartment building. However, it is also better to clarify all the details in advance. The type of plot is the determining factor.

    Limitation on the size of ADU Roseville, CA

    In Roseville, California, there are no restrictions on the minimum construction area that can be assigned the status of ADU. It all depends on your needs and material capabilities. And professional builders will help bring any of your ideas to life.

    However, in Placer County, there are restrictions regarding the maximum area of the building. They differ for a separate ADU and for an extension, so A+ specialists can tell you more about this at the first consultation. Regarding the height, it is usually always allowed to build a 16-foot-high ADU, that is, a one-story building.

    Requirements for parking spaces

    Since you are building an ADU on an already existing site, you will not have to deal with strict parking requirements. For an extension to the house, you do not have to create an additional parking space. If this is a separate ADU, then you will need to provide parking space.

    Minimum distance from the boundary of the plot

    You should take into account that no matter what size the ASU is, you must definitely comply with one more requirement: the building must be located at a minimum distance of four feet from the boundaries of your property along the perimeter. According to state law, this requirement is relevant for detached and junior ADUs. For junior ADU and a converted garage, you should definitely ensure fire safety. The distance that must be observed depends on this.

    ADU Building Roseville

    What advantages of building the additional residential property and working with the A+ company are there? Why should you be interested in paying for their services? You may be surprised, but in fact, having accessory dwelling units is useful not only in those rare cases when relatives or friends come to visit you.

    Constructing an ADU is a great and affordable housing solution in Placer County. Here are the main positive aspects about ADUs that you should know:

    Accessory dwelling unit as a place to rent

    You can rent ADU to other families or to one person daily or sign a contract with the lessee for a year. Having an accessory dwelling unit is a great option for having a permanent rental income in California. Investments in an accessory dwelling unit will pay off quickly if detached ADU is rented by another family. Of course, people will be willing to give more money if a converted housing unit or garage is located near the city center or in one of the prestigious areas of Roseville with good infrastructure.

    Additional living space for other family members

    In addition to providing accessory dwelling units to your guests, you can accommodate your elderly parents there so that they live next to you, and you can help them if necessary. In addition, this is an affordable housing option for your children to live in with no special permits required. They may have already grown up and want to start an independent life but have not yet accumulated a big amount of money to purchase their own house. If funding a new place in Roseville is a problem and the rent cost too much, you will be able to accommodate them in an existing place with great infrastructure.

    Housing solution to increase the property value

    ADU contributes to an increase in the value of the real estate. You can have an ADU and rent it to tenants daily or for a long time. If you multiply the amount of daily rent by 100, you will get the amount for which you will be able to sell your entire house in Roseville, Placer County, in the future. It is thanks to the presence of an additional extension that the sale amount turns out to be so large.

    Roseville is located in Placier County, north of Sacramento, the state capital of California, 164 kilometers northeast of San Francisco and 652 kilometers north of Los Angeles. The total area within the municipal borders is 79 km², the average height above sea level is 50 meters. The city is located on the eastern border of the Sacramento Valley (part of the California Valley), at the foot of the Sierra Nevada mountain system.

    In the town, the Union Pacific Railroad sorting station and the Amtrak passenger station are located. The 80th interstate highway also passes through the city. Buses connect Roseville to Sacramento and other cities in Placier County.


    The proximity of the Sierra Nevada Mountains affects the climate of Roseville, slightly different from the climate of neighboring Sacramento. The warmest month in the town is July, the coldest December, the most rainfall in January. The highest temperature, 46 degrees Celsius, as well as the lowest, 9 degrees below zero, was recorded in 1972 (respectively, in July–August and December


    Before the arrival of Europeans, the region where Roseville is located was inhabited by the Maydu Indian tribes. One of Maidu’s cultural centers was located on the shores of the River River, east of the modern center of Roseville. In 1964, the remains of yet another settlement of Maidu, located on the banks of the Dry Creek River, were discovered within the city limits.

    In the 1850s, after the gold rush along the streams and small rivers of this region, unsuccessful gold miners settled in agriculture. The rich soils along Dry Creek were one of the first to be cultivated. By the seventies, cattle breeding had already developed in the region (including cattle and pig breeding) and the first apple plantations and vineyards appeared. By the mid-1860s, the Central Pacific Railroad and the Central California Railroad passed through this area, the station at the intersection of which became the core of the future Roseville. Among the various versions explaining the origin of the name Roseville, the city site calls the most reliable one according to which the name of the village was given by numerous bushes of wild roses growing in the surrounding ravines. Roseville was first mentioned in newspapers during the presidential election of 1864, in which its residents supported Lincoln.

    The depression of 1893 gave way to a short-term gold rush in the Roseville area after the discovery of gold deposits, but the ore was poor or quickly depleted, and the boom ended by 1897. At the same time, the development of citrus plantations in the town began.

    In 1906, the sorting station of the South Pacific Railway was moved to Roseville, which turned it into a key transportation hub for the US Pacific coast. This caused an influx of new residents and building buzz. In 1906, the Roswell Chamber of Commerce was founded. In just two years, the Roseville population has grown five-fold, from 400 to 2,000. In 1909, the first elections to the city government, the Board of Trustees, took place, and Roseville officially received city status.

    In the early 1950s, the Roseville depot was expanded and modernized, and the city became the largest US rail terminal west of Chicago. The number of locomotives has grown in ten years from seven to four hundred. In 1956, the 80th interstate highway passed through the city, after which a gradual movement of the bulk of the city’s population to its eastern part began.


    In 2000, the population of Roseville was about 80 thousand people [8]. According to the US Census Bureau, by mid-2009, the city’s population had grown to more than 115.5 thousand people, which is an increase of 44.7 percent over nine years. Rapid population growth began in the 80s of the twentieth century. So, if from 1910 to 1980 the population of Roseville grew from 2,600 to 24,300 people, then from 1980 to 1990 the increase was more than 20 thousand people, and in the next decade 35 thousand people.

    In 2000, 86% of the population were white (including Hispanics); over the next nine years, the share of whites in the city’s population fell to 81.3%. The percentage of immigrants from the city’s neighbors grew during this time from 9 to almost 12 percent, while the share of Asian immigrants is growing most rapidly, accounting for 4.3% in 2000 and 8% in 2009.

    The average age of the Roseville population for 2009 is 36 and a half years, which corresponds to the average age for the United States; also roughly corresponds to the average American percentage of residents under the age of 18 and over 65 years of age. The population of the city is evenly distributed by gender.


    Roseville is a city with a high standard of living. The average annual per capita income in the town in 2009 was about 33.7 thousand dollars, per family about 88.5 thousand. Both indicators are significantly higher than the US average. Income of 6.6% of the population was below the poverty level, while on average in the United States 13.5% of the population received income below the poverty level. The unemployment rate in the town rose from 3.6% in 2000 to 10.6% in 2009, all the while remaining below the average unemployment rate in California, and only since 2007 has exceeded the average US unemployment rate.

    Education and culture

    The city has seven high schools and local branches of Hild College and Sierra College, a California network of colleges.

    Residents of the city use the services of three departments of the city library. In the town, the city theater, the art gallery of the Roseville Arts! Society and a number of museums, including the Maidu Culture Museum, the Telephone Museum, the Carnegie Museum of Local Lore and the Utility Exploration Center, the exposition of which is dedicated to the rational use of natural resources.

    Prefab ADU Construction

    What makes ADU service especially affordable is the prefab housing supply. Using already-made details for accessory dwelling units in Roseville is extremely profitable.

What is more, a contractor is able to complete the work faster so you can enjoy living in ADU or renting your new dwelling unit.

Thanks to the services of the A+ company, you can also reduce the stress level that usually accompanies the construction of residential units.
