    ADU Builders Stockton, San Joaquin, CA

    Your real property price will grow if your accessory dwelling unit (ADU) is built by a team of professionals who have enough expertise and skills to ensure high-quality accessory structure creation. This is why we strongly recommend you hire a company that works in Stockton city.

    Another reason to do so is that you have to know all the local laws and regulations regarding the topic and also need to get a permit to build your structure and get additional housing opportunities on your land plot.

    When you hire ADU contractors near me, you will not have to bother or waste your time, money, and nerves to get a permit: the company will provide affordable services and help you to receive the permission you need.

    ADU Contractor Stockton, San Joaquin, CA

    The process of creating an ADU near your multi-family or single-family home in Stockton city becomes easy, smooth, and quick when you hire the A+ Construction & Remodeling company.

    The team has been in business for over a decade and has qualified members who are willing to help with your project of any difficulty. A+ specializes not only in ADU construction but also in various remodeling and reconstruction operations. It will provide affordable services that will improve your household and its full facilities significantly.

    A+ operates in most Californian areas, including Stockton city, and is recommended by hundreds of homeowners in the state. You can check a vast portfolio of complete independent living facilities that bring joy to the company’s clients.

    In California and Stockton, San Joaquin county in particular, more and more people consider building themselves a multifunctional construction close to their primary dwelling unit: an ADU.

    The ADU acronym might sound unfamiliar to you: it means an accessory dwelling unit, a construction that you can build in addition to your existing primary dwelling unit and use it for different purposes.

    Homeowners love such units because they fulfill numerous tasks. In this review, we will define the types of accessory dwelling units, tell about some essentials that you should keep in mind when creating your accessory structure, and explain why having an experienced team of builders is vital for your project.

    ADU Contractor Building Types

    Before you create an accessory dwelling unit (ADU) structure near your primary dwelling unit, you must determine why you are building it. Every property owner who needs an accessory dwelling unit can choose from four different types and should consider all points and circumstances.

    Among the four types of ADUs allowed are the following:


    A detached residential dwelling unit is a common construction that helps you make your existing single-family dwelling or multi-family properties more attractive for different people: renters, if you plan to rent your place, or family members, if they wish to live with you but both of you understand that it will be impossible to share a building. Also, a detached ADU can be an ideal guest house when it is party time.


    When finished, an attached ADU becomes a part of your existing primary dwelling unit. The old and the new structure are connected, usually with a wall and a door. Such a unit is perfect when your family is growing: you are planning to marry someone or have a baby.


    Junior ADUs have limitations in size: they must not exceed 500 square feet. A junior unit is a great and affordable add-on to your existing single-family home or multi-family building.


    If you have a garage or pool house that you never use, why don’t you turn them into a beautiful attached or detached residential dwelling unit? Such units are called converted because you transform the place fully and begin using it for other aims than before. A garage or pool house turned into an accessory dwelling unit (ADU) can be extremely comfortable.

    As you can see, each type has its unique features and concept, and you can select the perfect type for your household. With a smartly built accessory dwelling unit (ADU), you can not only provide additional housing opportunities for independent living quarters but also create a home office, a vast storage spot, and so on.

    To ensure the successful creation of complete independent living facilities, homeowners normally hire companies that offer accessory dwelling unit construction from scratch. We recommend you consider signing a contract with such a business in Stockton city, San Joaquin.

    ADU Unit Construction Stockton, San Joaquin

    Before you dream about your perfect ADU structure on the same lot as your primary residence, you should consider several rules and regulations that exist in San Joaquin county and Stockton city. Regardless of what unit type you prefer – attached, detached, and so on – you will have to obey the local laws.

    We will not go deep into the list of regulations because it is rather long and requires your full attention. For instance, if one or more persons plan to live, sleep, and cook in the ADU structure, it will be considered a residential unit and must have a size of no less than 150 square feet. The maximum size is 1000 square feet.

    There are also rules regarding the size of rooms for one or more persons, independent living quarters, new structured parking near the unit, existing neighborhoods, setbacks, size of rooms for cooking and sleeping, and so on.

    Two parties know everything about ADUs allowed currently: the local government and construction companies. That is why it is necessary to hire a trustworthy entity that will help you with building your additional housing units correctly and in a cost-effective way.

    You are free to choose from three different floor plans for your ADU that will provide additional housing options for your family members, guests, or yourself. You can order a unit with one bedroom or two bedrooms and a kitchen with full facilities. All you have to do is hire a competent team of builders that will provide you with more care regarding your plan.

    ADU construction brings fantastic benefits to your life: check them out below.

    Benefits of ADU Building

    It does not matter what unit type you prefer; in any case, you will win, and your property will improve.

    Here are the general advantages property owners get when they complete their ADU projects:

    Property size increase

    You and your family will feel more comfortable when you have spare rooms that can become bedrooms or home offices. This is especially important for those who work from home and suffer from a lack of space.

    More housing opportunities

    You will be able to invite your family or friends to stay over without any limits, allowing seniors to spend more time with you in a detached or attached unit.

    Rental income growth

    If you ever decide to rent your place out, an ADU will become a great addition to your single-family house. You will be able to set a higher renting price than some existing neighborhoods. The same applies to property sales.

    Now that you know how you will benefit from an accessory unit let’s see how to pick your perfect construction team in Stockton.

    Stockton, San Joaquin ADU Construction Company

    Remember that if you do not hire a company, you will be potentially eliminating the risks that occur when you decide to build a DIY structure. So, it is essential to choose the company wisely and check additional information about each candidate.

    Ask someone you know for advice

    If there are people in your circle who you trust and who have recently completed a new construction, consider asking them about the companies they have worked with to implement their housing plans and dreams. Reviews from someone you know might be the most reliable and help you build a structure in a cost-effective way.

    Check the company’s documents

    It might happen that you will not get any good advice. Well, this is not a problem because you have the internet to conduct a proper search. The important thing to remember is that every company that provides construction services in the state of California must have a proper license to work legally. Do not forget to check that before you start cooperating.

    Go through the team’s portfolio

    Another thing that can help is checking the business’s portfolio, where you will see completed projects. Many companies have a gallery with finished works on their websites — pay attention to them.

    Read online reviews and comments.

    Lastly, you can always find a bunch of reviews from customers who have hired this or that team for their construction works. Truthful comments and negative reviews will help you avoid problems.

    From all entities in Stockton, there is a remarkable team of professionals who are willing to assist you in the construction of an accessory dwelling unit: the A+ Construction & Remodeling. Its supportive managers will provide you with more care than you expect, and its qualified builders will implement all your construction dreams. Do not hesitate to apply for a consultation via phone or email.


    ADU Construction Company Stockton, San Joaquin

    When you have found a company that meets your building standards, you will begin working together in accordance with the plan below:

    • Preliminary consultation
    • Meeting on site
    • Design development
    • Getting a permit
    • Construction.

    During a preliminary consultation, you will explain your needs and requirements to the manager, and then an on-site meeting will be held to see the location and plan the construction. The company’s designer will then offer a plan according to your description and comments.

    Then, a permit for your construction will be received with the help of the company’s specialists, and the construction itself will begin.

    After all the work is done, you will be able to check the results and inspect your unit. If something bothers you, team members will either clarify your doubts or fix their mistakes.

    Prefab ADU Construction

    Sometimes there is a problem moneywise, and your budget is not enough to build a fully-fledged unit. Do not worry: this problem can be easily solved thanks to a prefab ADU that can be installed on your land plot.

    Such units are built in advance and do not require additional workers and developers (designers, engineers, and so on). Consider signing up for this option if you need something simple yet convenient. The A+ company is also capable of installing such property units.

    ADU Housing

    As you can see, it is rather easy to create an attached or detached ADU near your existing property: all you should do is hire a team of smart specialists and be patient because construction will take some time.

    If you are still in doubt regarding new construction, remember that every property add-on is a huge improvement and a remarkable investment in your future.
