    Here are some of the most popular ADU types built in Yolo county:

    • Detached ADU;
    • Attached ADU;
    • Junior ADU;
    • Converted ADU.

    A homeowner can choose a particular kind of ADU depending on their needs and the purposes of creating the ADU. All in all, accessory dwelling units vary depending on their proximity to the primary residence and the size of the construction.

    ADU Unit Construction Madison

    Once the company starts working on the architecture of your ADU in Yolo county, the development of the plans begins. All the single-family and multifamily lots have their specificities that need to be taken into account during the creation of an ADU. For converted ADUs, the features of the existing space are also considered.

    Once the architect finishes with the planning, projects go to the city officials for approval. If your ADU is planned according to the law, a building permit is received. Then the construction can officially start.

    Benefits of ADU Building

    Building an ADU on your property in Madison can bring you the following advantages:

    1. Expanded living area;
    2. An additional source of income, in case of renting the ADU out;
    3. The increased cost of your property;
    4. A variety of usage options (guest house, home office, personal studio, or gym);
    5. More privacy to your family members.

    ADU Building Madison

    Homeowners who are planning to put an accessory dwelling unit on their property should know that the development of the ADU’s architecture must comply with local and state law. All the projects go through the procedure of receiving permits, and that is where the ADUs are checked for the requirements.

    Here are some of the law regulations for ADUs in California:

    • One accessory dwelling unit is allowed for single-family homes;
    • Every four existing residential units on multifamily properties are allowed to have one ADU;
    • In-law units must include fire sprinklers if the primary home has them;
    • The minimum size of an ADU is 150 sq ft;
    • The maximum size of ADU housing is 1,000 sq ft;
    • ADUs are subject to zoning regulations and 4 ft setbacks from rear and side property lines.

    The minimum lot size is not determined for Madison homeowners, meaning properties of any measurement can have ADUs allowed by the zoning requirements.
