    It does not matter what size your existing main house is. Sooner or later, it will not be enough, making you feel the lack of living space. It is a generally known fact. Even if you are a homeowner of a large residential lot with the main house of a significant size on it, someday you will think over some optimization of your home areas through the transformation of the existing space.

    In this case, you will have to search for an optimal and preferably economical solution to perform your housing addition somehow. The best solution for the property owners to increase the size of their living space is the construction of any type of ADU.

    The information concerning what the ADU is, its types, advantages, and search of companies rendering their services in terms of the Sacramento ADU construction can be found in this useful review.

    ADU Builders Rosemont, CA

    The accessory dwelling unit or ADU (as abbreviated) is a kind of secondary dwelling structure created on the territory of the single-family or multi-family property land as an addition to the existing primary dwelling residence.

    Building of such useful secondary additional structures has become very popular among property owners in all the areas of Sacramento County, California, including, of course, Rosemont, CA. It is not surprising because having spent a quite moderate amount of funds as compared to the purchase or construction of the independent primary house, you gain additional space for living, working, or storage.

    The ADU can be of the following main types:

    • Detached ADU. This ADU type is one of the most popular because it represents a separate secondary moderate-size building located close to the existing main housing on the territory of the residential lot.
    • Attached ADU. Such structures represent various additional attachments to the existing dwelling units, for example, the basements of your primary home transformed into ADU. The variants are numerous depending on the structure or the size of your existing primary residence, which is the subject of house addition.
    • Junior ADU (JADU). It can be attributed to the attached ADU and represents a minimum-size additional secondary structure amounting to not more than 500 square meters. Such a structure can be created only inside the existing primary residence.
    • Garage transformed to ADU. It is a kind of conversion unit representing the former garage turned to the new structure, whether by optimization of the existing space or through the addition of another story. In this case, we can use the new construction as the garage and the new living area simultaneously.

    There are some other types of ADUs, but the above-mentioned types are the most popular and widespread all over California state and the City of Sacramento (including Rosemont, CA, of course).

    It is clear that ADU construction has become very popular within the last decades. It is not surprising as the construction of additions to the existing main house has numerous obvious advantages for the property owners.

    All the ADU types can be used as follows:

    1. Living space for the members of your family or the guests. If you have a large family, having some additional space will always be in place. Additional dwelling structures can serve as housing for your children who grew up and require some independence, or for your guests who have to stay overnight and your ADU will help to house them.
    2. Working space for those who work from home. Having acquired some additional space due to the ADU construction you do not need to work somewhere in the kitchen or in your bedroom anymore. You have a fully-featured private office and an opportunity to work more fruitfully as a result.
    3. Additional income as a result of renting the ADU by tenants. It is a good way to invest your money to get the long-term source of additional passive income. Considering the fact that the bank interests are not that significant nowadays, such types of investments look much more attractive and sustainable.

    As you see, additional dwelling units enable homeowners to solve numerous problems in terms of the space for living as well as getting additional money as a result of their ADUs rent.

    When it has become clear that having your primary residence located on your property land is profitable it is the right time to find out the details of the process of the ADU building.

    The stages of any type of accessory dwelling units construction process:

    • Planning the budget
    • Project design
    • Costs estimates
    • Building permits acquiring (an important stage because ADU construction is subject to the number of certain regulations which must be observed)
    • Purchase of the materials
    • ADU construction works performance

    Although ADU is not a primary dwelling structure it requires a serious and accurate approach implying tons of preparation work and calculations.

    As to the regulations established in California in relation to the building of the secondary structures they are as follows:

    • On the territory of the California state as well as Rosemont, CA homeowners can build only attached, detached, and junior ADUs
    • If the ADU is detached it must have an independent access
    • The minimum lot size where ADU is planned to be constructed has to be not less than 5200 square feet
    • The additional parking place arrangement for the additional secondary structure is not allowed
    • The maximum height of the detached new single-unit dwelling must not exceed 16 feet whereas the ADU total area is limited by 800 square feet irrespective of the lot type (single-family homes or multi-family property land)
    • The design of the potential additional secondary structure must not conflict with the overall design of the existing primary residence and other buildings located on the territory of the residential parcel
    • The ADU shall be supplied by water and electricity from the main primary housing

    It is very important to observe the above-mentioned regulations established by the Department of Housing and Community Affairs on the territory of the state because failure to observe them will result in the denial of the ADU building permits and all the necessary documents acquired.

    ADU Service Provider Near Me in Rosemont, Sacramento County?

    Undoubtedly the assistance of a representative of the construction business is required for you to prevent money and time losses in case of your ADU construction project failures. Of course, the services of such a company which is called the building contractor (or general contractor) are not free. And yet, in return, you have your project completed on time, without any unexpected additional costs. In reality, the construction company saves your money, so your costs in case of cooperation with it will be less than trying to organize all the building process all by yourself.

    When we have convinced you of the necessity to hire a reliable construction company, it is worth mentioning that in the process of your search, you should pay much attention to some details which will help you to distinguish the best one.

    A good ADU building services provider must have a good portfolio of completed numerous ADU projects, an excellent experience and expertise, and positive customer reviews. Additionally, liability insurance and the license are required for you to feel confident that it will complete your ADU project having avoided unpleasant situations when some damages and breakdowns occurred and can not be covered.
