    Finding the Right ADU Contractor

    Finding the right Accessory Dwelling Unit (ADU) Contractor is very crucial for the success of your whole project. The following must be considered when finding your right ADU Contractor:

    • Relevant Experience: The choice of the contractor should be a person who has completed ADU projects similar to what is envisioned. For instance, if your need is for an attached ADU, then your choice of contractor should be one that has experience in that kind of construction.
    • Licensing: The professional must be duly licensed by the appropriate local authorities in respect of all licenses and permits required by relevant codes and regulations.
    • Reputation: The contractor must be reputable in the community. Good reviews and topmost ratings from previous customers are proofs of good service.

    Golden State ADUs is one of the best-ranked contracting companies in Placerville, which fulfills these key requirements for offering the best ADU services.

    Types of Accessory Dwelling Units

    There are different kinds of ADU, each serving various characteristics and advantages:

    • Detached ADU: A freestanding, separate structure from the primary residence, one or two stories. It is ideal to let or provide additional family accommodation.
    • Attached ADU: Shares at least one wall with the main house. These are generally faster to build. It can be used for various purposes: an office, theatre, or even a bedroom.
    • Garage Conversion: This typically involves the conversion of an already existing garage into something new; it could be a workshop, playing area, or any other place of storage.
    • Basement Conversion: Most involving a project that could transform your basement into a wine cellar, gym, or library by adding functionality to your house.

    Not only do each of these options raise the bar in terms of market value for your property, but they also add up to an enhanced living experience when done by an experienced contractor.

    Legal Considerations in ADU Construction

    Working with an ADU construction company will help you wade through any legal concerns about the structure. Regulations are different for different places, and it helps to have a contractor accustomed to the rules of Placerville in particular. A good example would be those regulations concerning zoning when converting a garage.
    At Golden State ADUs, our staff has professionals well-versed in California building codes for the smooth and timely processing of your permits.

    Reasons You Should Consider Building an ADU

    Investing in an ADU comes with several advantages:

    • Passive Income: One can gain passive income by renting out the ADU, thus compensating for the construction cost of the ADU.
    • Family Room: The ADU will give you extra family room with additional kitchen and bathroom amenities.
    • Home Theater: Designate a room as a home theater with which one can have a better experience viewing his/her favorite films.
    • Home Gym: Turn the ADU into your gym area where one can work out in the comforts of their own space.
    • Other Uses: Use the space for a studio, children’s play area, or a children’s educational room.

    To enjoy the above benefits, an Accessory Dwelling Unit Builder that is well-licensed must be consulted. Golden State ADUs will provide you with honest and excellent service.

      Golden state design did the design and engineering for my custom home. From the start William and his team were beyond helpful. The plans were well thought out and easy to read. Throughout the project any questions I had, William made himself available to answer very promptly. In addition to this, Golden State took on several other projects for us, and the results were just as great. William prepared all of the paperwork, filed with the county and did any revisions the county needed. I am beyond happy with their service and would recommend them to anyone. I will be doing an ADU in the near future and I can’t wait to see what golden state design can help us come up with.

      Recently had the pleasure of working with Golden State on a restoration project, and I must say, they surpassed all my expectations. We hired them to handle the design, drafting, engineering, and permit acquisition, and their expertise and professionalism were truly outstanding. From the moment we brought Golden State on board, it was clear that we had made the right choice. Their team, led by William, displayed an impressive level of knowledge and skill throughout the entire project. Their attention to detail and commitment to excellence were evident in every aspect of their work. They took the time to understand the unique requirements of the restoration project and delivered a design that perfectly balanced modern functionality with the preservation of historical elements. Their ability to capture the vision of the project and translate it into a comprehensive plan set was truly impressive. They paid meticulous attention to every detail, ensuring that all specifications were accurately represented in the drawings. As well as addressing the structural challenges. One of the greatest advantages of working with Golden State was their ability to handle the often time-consuming and frustrating process of obtaining permits. They took charge of the permit acquisition process, liaising with the necessary authorities and ensuring that all documentation was submitted promptly and accurately. This saved us a significant amount of time and allowed us to focus on other aspects of the project. Throughout the project, William and Yasir were reliable and responsive points of contact. They maintained open lines of communication, keeping us informed of progress, addressing any concerns promptly, and providing valuable guidance and expert advice when needed. Their professionalism and dedication to client satisfaction were truly commendable. Thank you, Golden State Design and Engineering Firm, for your exceptional services!

      I hired William to design my ADU for me! They are very responsive and efficient! After we got the permit from the county, they are still willing to follow up if I need to make some changes to the permitted plans. And when my contractors have questions about the plans, they are willing to spend the time to discuss with my contractors. I really appreciate their help!!!

      William built an ADU in my backyard. He handled everything from planning and getting permits to construction (only the original home plan was my idea). Some jobs (foundation, roof, HVAC, electrical, stucco, etc.) were done by subcontractors, but William was closely monitoring the work during all phases and his team did a lot of hands on jobs (site preparation, framing, insulation, interior, cabinets, painting, etc.) as well. In a few instances, William came up with the solutions that saved me thousands (he figured out how to set up electrical without having to add a new panel, chose the optimal option for solar, etc.). I'm very happy with the end result and would not hesitate to recommend William and his company for any type of construction or remodeling jobs.
