        In recent years, the accessory dwelling unit (ADU) has totally reshaped the construction business. They have conquered the hearts of many homeowners, and this process doesn’t seem to stop in the nearest future. Consequently, one has to seize the moment and take advantage of accessory dwelling units as fast as possible.

        ADUs, which are sometimes called granny flats, laneway houses, in-law units, or backyard cottages, are a sort of additional apartment located on the lot where you already have a main house. A grand number of homeowners in California have already built such units on their property and significantly increased the total living space. Perhaps, it’s high time you built one on your lot? If you’re looking for an ADU contractor near me, A+ Construction & Remodeling is here to help. Contact us to get started on your ADU project today!

        ADU Builders Mather, CA

        Even though the construction of accessory dwelling units seems like an easy task at first glance, in reality, it is quite a difficult process. In order to avoid any inconveniences, we advise you to hire professionals like A+ Remodeling & Construction. Our team will meticulously control the entire process at every stage and ensure that the completed project will be done with proper quality and on time. Our key benefits in comparison to other companies you can find below.

        ADU Contractor Mather, CA

        The right choice of a general contractor is the cornerstone of any quality accessory dwelling unit (ADU). They are normally in control of everything, from ADU design to legal documents and any law issues. Having years of experience in this sphere, we have figured out the factors that you have to pay attention to if you seek the right contractor.

        The basic factors that can help you with the choice are:

        1. Legal documents. Every contractor has to possess certain legal documents in order to operate in this field. Typically, you can check them on the site or ask the manager to provide them. In case you don’t see these certificates, we would think twice about having any business with this company.
        2. Credibility. You can find people who have worked with this contractor on certain forums and ask about their experience of working with them. Moreover, ask around in your location before you begin working with a company; probably someone nearby can tell you more about them.
        3. Portfolio. The created projects can also say a lot about a general contractor. You can notice whether their designs fit your vision of an ADU and decide on working with them or not.

        Read this article till the end to find out more about accessory dwelling units, for example, the cost of the project, different ADU types, and different ways to use your new property.

        ADU Contractor Building Types

        There are many variations of ADUs that can be built on your lot with an existing main house. In Mather, A+ Remodeling & Construction can build the following accessory dwelling units.

        Attached ADUs

        This accessory dwelling unit represents a new construction created by home builders on your lot. Typically, one wall is shared with the main house, which allows the company to decrease the cost of it. The growing families love this option as it allows them to have more living space without the necessity to build new detached structures.

        Detached ADUs

        Being the most expensive option on the list, this type also provides the highest levels of privacy to the tenants. The detached structures will be placed on your lot and look like a new house built in the same yard as the main house. It will have all the necessary utilities and a separate entrance, so no one will interfere with the life of the family living there.


        If you feel like your unused room could be transformed into a convenient living space that can generate rental income, this option is for you. The conversion will allow you to get the advantage of an already existing room in the main house or, for example, a garage, so overall, the whole process will cost you less money.

        Junior ADUs

        Junior ADUs, or JADUs, are actually not that different from the regular ADUs and can still accommodate tenants; however, the distinctive feature of this type is the size. The completed JADU cannot exceed 500 square feet. This secondary housing unit is a great option if you are not willing to spend a fortune on an accessory dwelling unit but still want to have one.

        ADU Unit Construction Mather

        Before coming to the office of the contractor, you have to make sure about the possibilities of broadening the existing space. Typically, an accessory dwelling unit is subject to various regulations concerning, for example, zoning. Construction codes and various permits also have to be taken into consideration.

        However, a reliable contractor will also take care of these regulations with the help of lawyers. A+ team will complete the project as fast as possible and without any inconveniences so you can accommodate tenants and generate rental income faster.

        Benefits of ADU Building

        If you are struggling to determine whether you actually want this structure like an accessory dwelling unit (ADU), the list of benefits will definitely help you make the right decision.

        The advantages of building an ADU are:

        • Extra income

        ADUs are great means of generating rental income, as you can rent them out to anyone you want. Granny flats can fill your family budget and later serve as an apartment for the kids.

        • Space for seniors

        None of us is getting younger, and your mother and father are no exceptions. With time they will need proper care, so keeping them closer to you seems like a logical decision. Instead of quitting your job to start taking care of your parents, you can begin now and create a living space where they will live.

        • Investment

        Any builder will tell you that, unlike money, the property doesn’t lose its price with time. Hence, to save money, one has to invest it carefully. Rental property like ADU can create a financial cushion in case of any unexpected events. In the future, you will be able to sell your whole lot at a much better price.

        Mather ADU Construction Company

        Every general contractor has its pros and cons, and the main goal of every owner is to find, in which case this proportion is in favor of advantages. A+ Construction & Remodeling will, for sure, provide you with a quality ADU built on time, but there are many more benefits that we have.

        Take a look at the following benefits:

        1. Continuous feedback. If you notice that something goes wrong in the building process or want to add something new to the dwelling, you can always address any builder you see on the site. They will later tell your thoughts to the managers and together find a solution to the problem.
        2. Free consultation. Before signing a contract, you have an opportunity to come to our office, where we can discuss the whole project from the beginning till the very end. Also, you can ask any questions concerning the process to the team to get the complete picture of the project.
        3. Sensible rates. Yes, building the additional apartment is not a cheap process; however, our job is to provide every client with reasonable prices for every ADU type, be it attached, detached, or even a garage conversion. During the building, we will do our best to decrease expenses without compromising quality.

      • Frequently Asked Questions

        Where can an ADU be located?

        We can begin the construction of an ADU anywhere your property allows us to do so. Depending on the type, different locations can be chosen. Don’t worry; our team will evaluate beforehand the best place for an ADU. As in-law suites require a certain place in order to correspond with the nearest buildings and for better access to the utilities, this process may take some time.

        Can I make any adjustments to my ADU?

        Yes, you can. Right after our builders leave your backyard, you can do anything you want with an ADU, as it is your property, and we cannot interfere according to the law. So, any idea that you have in the head concerning your ADU may be realized, but without help from us.

        Can the design be changed in some way?

        On demand, we can adjust certain moments in the ADU design, for example, changing the tiles in the bathroom or adding more lights to the living room. However, these options have to be discussed before we begin, as it will be quite difficult to switch anything in the process, no matter whether it is an attached or detached ADU.
