Today it is already impossible to find a person who has not heard about accessory dwelling units. This concept is well known to owners of small private houses, as they often face a shortage of living space for various reasons. If you’re considering building an accessory dwelling unit, it is advisable to consult with an ADU builder to ensure a successful and efficient project.
Many homeowners think that they can complete an ADU project without outside help. However, we can say with confidence that most amateurs make mistakes even when repairing one room. However, an ADU is a multidimensional structure, and the slightest discrepancy with standards can lead to fatal consequences. In this regard, cooperation with a highly qualified contractor is necessary for everyone.
At one time or another, almost everyone who has a small house needs to increase their living space. For example, someone has children growing up. Others decide to take an old grandmother, and so on. The ADU project perfectly copes with any household issues. In this review, we will tell you about the types of accessory dwelling units, take a detailed look at all stages of construction and help you find a good general contractor in Yolo, California, who will implement the ADU project for you at a high level. We will try to do this in a short but extremely accessible form.
For the construction of a new living space to go smoothly and without problems, you need to know some nuances when selecting a contractor. It should be not only expert ADU builders but a big team of professionals, including lawyers and designers.
In addition, the focus of your attention should be directed to such important details as:
On the whole, when all of the above is taken into account, it is not difficult to pick the right contractor. If we compare all the factors, it will turn out that A+ Construction & Remodeling will be among the first who has the highest level of loyalty among buyers, trust, and an impeccable reputation.
Even those who have already encountered the concept of ADU do not always know that there are several types of accessory dwelling units. The construction industry has stepped so far forward that nowadays, homeowners have a choice of several dozen ADUs with different functionality, design, and layout.
Usually, the realization of this project is resorted to in cases when the property territory is not designed for the construction of a detached building; the homeowner is limited in funds, or other types of ADU are prohibited by the legislation of the city or county. Nevertheless, this type of ADU can be called an autonomous space since it is equipped with all basic life support systems. The attached ADU also has a common wall with the main house, a separate entrance, and, in some cases, an additional adjacent door to the main building.
This type of accessory dwelling unit is a tiny detached home, and sometimes people call it a granny flat or guest house. This is a very common option of ADU, which is picked by homeowners when both the backyard area and the funds permit the project to be implemented. In such a building, you can find a kitchen, a bedroom, a bathroom, and all life support systems.
This option implies a complete reconstruction of the attic place for living space with strict compliance with all construction and fire regulations. Unlike the traditional idea of attics as cold and empty places, the ADU attic project is a fully-fledged accessory dwelling unit that has all the comfortable conditions. It can be one large space, for example, as a music studio or as an apartment with a bathroom and a bedroom.
An excellent option to acquire additional living space is the conversion of the garage, especially if it is not used for its intended purpose. Garage conversion allows you to realize all your ideas and dreams, as you have the opportunity to create a home theater, a home gym, a small art gallery, and much more.
Each of these variants of ADU deserves your attention. However, to meet all your expectations, we advise you to carefully choose a general contractor. To do this, you need to familiarize yourself with the main selection criteria, which we will discuss in the next part.
As mentioned earlier, the implementation of an accessory dwelling unit draft on your territory must be executed by the permitting of the local authorities. The lawyers of the company are obliged to inform customers as much as possible about all the legal components of the project. Everything must be taken into account, in particular, local codes, zoning, the number of permissible square feet, or the height of the building.
A+ Construction & Remodeling lawyers involved in the realization of all projects are ready to provide legal assistance to house owners at all stages of the working process.
It is indisputable that any ADU model multiplies the monetary value of the property, as an accessory dwelling unit attracts the attention of clients in the real estate market. Also, the presence of ADU can expand the family budget in the case of renting out a new living space. However, what are the other advantages of additional units?
Let’s analyze every detail:
On the whole, as you can see, the benefits of building an ADU are enormous and exceed any expectations. You will start using these privileges faster if you choose an A+ company, which is famous for its high level of workmanship and amazing experience in this business.
The main distinguishing features of an A+ company are high-quality work and a professional approach, as well as super-qualified personnel. A+ is ready to provide each client with a personal program for the implementation of the accessory dwelling unit project.
A+ respects customers and is always ready to guarantee assistance at every step, and that’s how it is expressed:
All in all, except for A+, there is no such company that would develop a program for each client so thoroughly and scrupulously. This is the most responsive and professional builder in Yolo, California. To start cooperation, contact our managers to get a free estimate asap.
As we noted earlier, the functionality of accessory dwelling units is almost limitless, and now you will see it again. Firstly, as an ADU, you can build a second story in which an additional bedroom or a room for watching movies with your family can be located.
Secondly, by analogy with granny flats, you can build a two-story detached ADU, which will be equipped with two bedrooms. The price tag for such projects is higher. However, there are more profits.
Finally, you can equip the man cave, where you can install a billiard, a mini bar, table football, and everything that will make the pastime more fun.
If you are looking for access to the implementation of an ADU project at a lower price, then your choice is prefab ADUs. The essence of such projects is that the ADU is completely assembled at the factory, and then the company issues its supply immediately to your site. You just have to do only a cosmetic job. For example, choose furniture, carpet, frame for windows, or tile for bathrooms.






Investing in ADU is one of the best solutions which permits you to make living conditions more comfortable and practical for all family members. For the project to meet all your expectations, you will need good company, and in Yolo, California, an amazing job is performed by A+ builders.
It is difficult to give an unambiguous answer to this question because construction costs depend on many factors. However, we can designate ranges, so the cheapest options are junior ADU and attached ADU, and the most expensive are a two-story garage conversion or detached ADU.
A garage conversion is one of the varieties of ADU drafts when you make a technological and comfortable room out of an old and cluttered garage. For example, garage conversion may result in a home gym or an additional room for children.
Constructed ADU on your site instantly increases the cost of the entire property, permits you to comfortably accommodate all guests and family members, and makes life more practical at the same time cozy.
Without the help of a lawyer, it will be very difficult to get all the necessary permits for construction because different rules apply for each city in California. A lawyer will help you with the correct zoning and planning, as well as protect you from getting a ban on construction.
Every accessory dwelling unit in El Macero needs a building permit. Applications are reviewed by the Yolo County Building Division (or your city building department for incorporated areas), which checks your plans against California’s statewide ADU law and the local zoning, building, and fire codes for Yolo county. As a full design-build contractor, A+ Construction & Remodeling prepares the drawings, structural calculations, and Title 24 energy documents, then submits and manages the permit on your behalf so you don’t have to navigate the counter alone.
Under current California rules, most ADUs are approved ministerially - meaning no public hearing - and the jurisdiction must act on a complete application within 60 days. Key statewide standards that apply in El Macero include:
Local factors in Yolo county - such as septic vs. sewer connections, fire-hazard zones, well water, slope, and utility upgrades - can still affect your design, timeline, and cost. We evaluate these during a free site review and build them into your estimate up front, so your permit moves through the Yolo County Building Division (or your city building department for incorporated areas) without surprises.
