        According to different estimates, California is one of the top states in the country in terms of living conditions, economic development, and, as a natural consequence, the highest accommodation costs. In such an event, as a means of increasing housing affordability, the spread of accessory dwelling unit, or ADUs, began.

        More and more people in Sutter, California, favor ADU projects to add extra income to their monthly earnings, accommodate guests, or reduce their own living expenses.

        And, of course, to get their neighbors impressed with their beautiful small custom homes created by professional building and design ADU contractors like A+ Construction & Remodeling!

        ADU Builders Robbins, CA

        Accessory dwelling units can be classified on several grounds, including:

        • According to their proximity to the main house: attached or detached ADUs. As the name implies, the attached ADUs are adjacent to the house by one wall, forming an integral structure. At the same time, a detached ADU is an entirely separate, stand-alone construction located on the same plot as the main house.
        • According to the type of building process: new construction or conversion. An architectural project may assume that your building will be built completely from scratch, or it may be rebuilt from an existing structure. For example, a half-empty garage, a cluttered attic, or a rarely used basement.
        • According to the size: full-size ADU or junior ADU. If a full-sized ADU can reach 850–100 sq. ft., a JADU’s size is restricted to half of that – 500 sq. ft. max.

        When thinking through your ADU project, pay attention to what exactly you want to build and for what purposes. If you need help making a choice, consult with the A+ Construction & Remodeling team!

        ADU Contractor Robbins, CA

        Think about the ADU construction process. Have such details as building a roof rainwater drainage system or considering fire hazards immediately come to mind? How good is it when a person with extensive practice asks a clarifying question, remembering this and other vital things for you?

        To build a tiny house, you will need professional ADU building services. There is a reason why the construction of a dwelling unit requires a whole team of architects, builders, designers, and engineers. That is because they have both deep knowledge and work experience in the field, whereas a layperson may struggle to learn at a rapid pace. Moreover, understanding state and county laws and ADU regulations gives them an upper hand in dealing with permit acquisition, a severe headache for any house owner.

        ADU Contractor Robbins

        There are many ADU builder companies operating throughout the country, and A+ Construction & Remodeling is one of them. But what made this contractor earn the title of a company that earned trust?

        You can visit the main page for more information, but the main reasons include the following:

        1. Work experience in the construction field

        For more than twenty years, we’ve been providing California clients with building services. We completed numerous projects and left thousands of customers satisfied. Also, we have selected specialists (builders, architects, engineers, and designers) from all over the country to form a highly qualified crew for embodying an ADU project of any level of sophistication.

        1. Licenses and photos

        We are glad to confirm our words with deeds. But until then, A+ specialists can offer you the chance to familiarize yourself with the licenses, certificates, and awards presented on the website. And also with photos taken by our employees on the completion of ADU projects in various cities in California state.

        1. Dedication to schedule

        A thoroughly planned work process, from the overall architect’s plan to the design of every single cushion, is what allows us to make predictions about the timing of the completion of the new construction.

        1. The cooperative relationship between the builder and the client

        Despite the fact that the benefits for us are different, it’s a common purpose that has brought us together. That is why open communication and joint planning are so important to us. So important that the first week or a few are dedicated exclusively to finding out what you want to see on your property.

        ADU Unit Construction Robbins

        In the context of an ADU project’s development, red tape is something that can be considered a blot on the landscape of the creative aspirations for ADU configuration, location, and design. City and county regulations contain several requirements that you must meet to receive permission to embody your fantasy into reality.

        First of all, a tiny house is still a house, i.e., a space designed for permanent living. Therefore, an ADU shall consist of a kitchen to prepare food, a bedroom to sleep in, and a bathroom to take a shower in.

        Secondly, the ADU ordinance prescribes the ADU number and possible sizes. Thus, one family living on the plot may have one ordinary ADU (attached or detached) and one junior ADU (converted). Multi-family households are allowed to have one ADU per four existing dwelling structures. The minimum ADU size is 150 sq. ft., while the maximum ADU size is 1000 sq. ft. for a two-bedroom ADU and 850 sq. ft. for a one-bedroom ADU. Junior ADUs cannot surpass the limit of 500 sq. ft.

        If you doubt the correctness of your concept, ask an A+ builder to answer questions about your particular piece of property and its peculiarities.


        Benefits of ADU Building

        Starting an ADU project with A+ Construction and Remodeling gives you a great chance to:

        1. Strengthen family relationship

        Dwelling units may be designed as granny flats, apartments for newlyweds who have not yet saved up for separate housing, or for college students who strive for personal space and privacy but want to remain in the local community.

        1. Create extra space for guests’ accommodation

        If you are a house owner who wants to take pride in housing big holiday events on your land plot or you belong to people who have many other city friends and relatives, an ADU is for you. After all, a fairy garden cottage or a modern loft dwelling is way better than a cramped common bedroom and hence cranky roommates, isn’t it?

        1. Separate work and personal life

        Many people have been dreaming of working closely at home or, even better, from it. If your job allows you to make a living from your four walls without wasting time on the road, then what else can you wish for? Well, for example, silence. And it’s in your power to create an equipped space where none of your family members would disturb you within working hours.

        1. Architect a source of additional money

        If the owners of the house in Sutter County, California State, decide to rent their ADU out, they can earn from $1,000 to $2,000 (depending on the size and looks) per month. Moreover, property appraisers claim that a full-sized, solid ADU with an inviting interior and exterior design may add about 30 to 40 percent to the cost of a plot with a house for sale.

        Most importantly, you can use ready-made ADUs for all these purposes combined! Reach out to A+ builders to order an excellent construction job with respect to your priorities!

        Robbins ADU Construction Company

        A+ Construction and Remodeling applies modern technologies to enhance your customer experience. Thus, after the architect has finished with the plan, the designer can visualize your idea with the help of 3D modeling software. So you can see in advance what the result will be for you and make adjustments if necessary.

        At A+, we take care of the environment around us so that the city where you live remains clean and its inhabitants, healthy. That is why we carefully adhere to the environmental friendliness of the technologies and materials we use.

        Prefab ADUs are modular, factory-pre-made units of typical configuration and limited designs. Unlike custom-made ADU, prefabricated ADU does not require the effort of engineering drawings set up individually as well as material selection and development of design solutions. That’s why they are several times more affordable and can be built in a record time of 2–3 months.

      • Frequently Asked Questions

        Can I have two JADUs that total to 500 sq. ft. if add up?

        California ordinance prescribes that a single-family plot can only have one full-sized ADU and one junior ADU, no matter the size (if it is less than 500 or equals it). Thereby, this rule excludes the possibility for one family to have more than one junior ADU on their land. However, you can still have two additional residential units of different types.

        At what season is it better to start an ADU building?

        As with a classic house, usually, the best months to start construction are the late spring months (April, May) and all summer months (June, July, and August). The most important works, such as making a foundation and erecting walls and a roof, need to be completed in good weather. Therefore, if you want to start construction by this time, try to take care of planning earlier than in March.

        How much does a prefab ADU cost?

        The price of a small prefab unit can range between $60,000 and $100,000. It is three-to-five times cheaper than a typical custom ADU. However, depending on the size, configuration, design, and materials used, this moderate sum may rise exponentially. Therefore, it is better to check the exact price with the contractor, who will show you a catalog with available ADU options.
