        The lack of affordable housing options across the US, coupled with drastically increased costs, leads to a problem becoming more visible. In response to this challenge, contractors across the country have put forward the idea of small but efficient housing units: ADUs.

        ADU cost Sacramento is a significant factor to consider when exploring housing options in the area. Accessory dwelling units are small houses equipped with all the facilities inherent in residential premises. Being blocks installed on the same plot as the primary dwelling, they belong to the means of low-income housing as they don’t present difficulties with the acquisition of another piece of land and, taking into account a number of factors, can be significantly lower in price.

        ADU Builders, University of California-Davis,CA

        Building an ADU is a full-scale construction undertaking that demands a certain level of expertise. How do you construct a long-lasting ADU from the right materials at a reasonable cost while experiencing minimum setbacks in construction technology?

        Professional contractors for accessory dwelling units specifically focus on managing the construction process in the most effective way. When they apply housing innovation methods, they use only high-quality materials that will stand the test of time and weather conditions. Also, ADU specialists have knowledge in the fields of federal law, state law, and regulations at the local level; this makes it easier to obtain permits and prevents the need for costly rework in the case of unacceptable construction.

        ADU Contractor Building Types

        So, what forms can the ADU building take? Majorly, builders in UC Davis city offers the following types of additional living space arrangement:

        1. A detached ADU. This is a completely new construction located on the same lot as the primary residence. Building an aesthetically pleasing, secluded ADU with a separate entrance may bring forth good monthly additional income if the ADU unit is used for rent.
        2. An attached ADU. Homeowners turn to the construction of an ADU adjacent to the house if they want to have a minimum of restrictions on access to additional living space. For example, if they want to take care of somebody who lives in a granny flat.
        3. Garage conversions, attic conversions, or basement ADUs. A single-family home is allowed to arrange an accessory dwelling unit instead of unused space inside their home or garage. This option is faster and usually cheaper than starting from scratch. Moreover, it allows for the full use of every inch of existing property.
        4. An ADU above the garage. As in the case of conversion, this option is especially suitable for homeowners whose plot is not too large. There is no need to squeeze the tiny house somewhere else if the roof of your garage fits perfectly under it.
        5. A junior ADU. Among secondary units, this one has the strictest restrictions on size (up to 500 sq. ft.) and on the method of construction (only from an existing unit) but has fewer restrictions regarding other points of the ADU ordinance.


        ADU Unit Construction at University of California-Davis

        Accessory dwelling units are the subject of several regulations. Thus, the ADU ordinance adopted by the Davis City Council prescribes the maximum size of an ADU, which is 150 sq. ft, as well as its maximum size, which varies depending on the number of beds: 850 square feet for single-bed ADUs and 1000 square feet for two-bed ADUs. In addition, junior ADUs cannot exceed 500 sq. ft. and must be converted rather than built anew.

        As to the maximum height of an ADU, in Davis, CA, it’s typically restricted to 16 feet, with a few exceptions.

        The number of ADUs per family is also restricted. Single-family homes are entitled to have one ADU in full size and one junior ADU in case the homeowners currently live in the main residence. As opposed to a single-family residence, multi-family residence depends on the number of buildings already made, but typically it is allowed to have one ADU per four existing residential buildings.

        Benefits of ADU Building

        Accessory dwelling units are a good choice for many reasons. ADUs are suitable for the purposes of accommodation, extra income, care for loved ones, creating a minimalistic personal space, economical living, and all this together.

        Thus, the main benefits of building an ADU include the following:

        • Providing housing for young adults on your own land plot. A detached ADU for grown-up children is a budget-friendly way to give them freedom and independence while staying close to back them up.
        • Home offices for remote work, studios, and workshops. When you’re struggling with total task concentration, it’s important to keep family members at bay. Increase your productivity by organizing a workspace in a secluded house with all amenities within walking distance.
        • Guest houses. If a single-family residence exists in a rather cramped environment, housing friends or relatives from another city, even for the weekends, can get tricky. Therefore, in order not to urgently arrange a rearrangement of furniture and not to drag an old cot out of the garage, some homeowners took care of a small but functional cottage in advance for a joint holiday on their plot.
        • Granny flats. ADU builders offer detached granny flats for aging parents who can live on their own but for whom it’s hard to pay the separate accommodation costs due to low income. On the other hand, detached ADUs and conversions will do for the elderly, who need constant supervision.
        • Rental income. With California’s large population and hence limited housing stock, not everyone can afford to build their own house in the city they want to live in. It’s especially relevant for college and university students. Thus, ADU is a win-win situation. With the help of this housing innovation – an ADU, moderate-income households can increase their monthly income. Rental housing allows students to save commuting time for rest and actual study.
        • Increasing property value. If selling is in your future plans, an ADU building is a way not only to recoup the cost but also to make some money. Especially considering that you can choose not one but two financing options: first, use an ADU with affordable rents to earn a certain sum monthly, and then sell the property in full, receiving a benefit of 30 to 40 percent more.

        • Architectural drawings, flooring plans

        Designing with interests and architects is the most important part of the preliminary stage. Therefore, our competent specialists plan the design so that in the future, you will not have unforeseen problems.

        • Selection of materials

        Why do Yolo house owners count on us? Because A+ Construction and Remodeling have close ties with the best of the local building material suppliers. We choose quality so that your ADU has both an appealing curbside and long-lasting solidity.

        Building an ADU at University of California-Davis

        Before getting on the path of building an extra residential unit, Yolo County homeowners first go through a period of preparation, which includes the following stages:

        1. Initial consultation, at which the A+ team will get acquainted with your plans and go through the general questions about the future project.
        2. Free estimate, during which we will make a detailed list of works and calculate the exact amount of upcoming expenses.
        3. Signing an agreement, which will finally consolidate all the rights and obligations of both parties.

        Also, throughout the entire workflow, convenient communication will be established between the client and our team. After all, the more we discuss the project, the more often we compare what’s going on with the conception, and the more the final result will correspond to your wishes.

        Prefab ADU Construction

        Autonomous units belong to the means of affordable housing because they are, in fact, affordable. Thus, for low-income households or homeowners who do not want to bother with tedious planning and design, there is an opportunity to acquire a prefabricated, modular ADU.

        A prefab ADU is the same ADU but previously engineered and partially assembled at the factory. Ready-made ADUs are constructed according to standard drawings, and therefore, when ordering such an ADU, you will not have any costs for individual planning and the selection of design solutions.

        ADU Housing

        All in all, versatile ADUs are a very useful community innovation that brings benefits to all parties. Being a source of work for us and income for homeowners, ADUs also partially solve the problem of housing affordability, not only for the owners but also for the tenants of this housing. UC Berkeley Center conducted governmental studies that indicate that further spreading of ADU is still needed to cover the affordable housing shortage, especially for those who’re low-income qualified. So, together with you, we help very low-income families find a decent and sufficient place to live.

        So, if the short-term or long-term benefits of these buildings are what you are interested in, do not hesitate to contact А+ Construction & Remodeling!

      • Frequently Asked Questions

        How much does it cost to build an ADU in Yolo, California?

        Depending on the size, attractiveness of the design, and popularity of the area, the ADU price may vary significantly. That is why A+ offers a free estimate. However, if you calculate the average, taking into account the fact that an sq. ft. of an ADU may start at 100 dollars and go up to 400 dollars, a 1000-square-foot ADU may cost you $100–$400,000.

        Do I need a permit to build an ADU in University of California-Davis, CA?

        For the construction of residential premises both from scratch and when converting from a garage or other existing building, a construction permit is required. A+ specialists will help you trudge through sophisticated ordinance language and, as a result, consider all the features of the building inherent to your area to easily obtain all the necessary permits from your city government.

        How long does it take to build an ADU in California?

        Taking into account the preparatory stage, which includes planning, obtaining permits, and a design project, the construction of a custom ADU can last about a year. At the same time, the size and complexity of the ADU are of great importance. So, junior ADU will typically take several months, while prefab ADU may take a couple of months.
