Construction of Accessory Dwelling Units in California: Pros and Cons


    It’s important to weigh the pros and drawbacks before deciding whether or not to build an ADU in California. On the one hand, ADUs have the potential to provide homes for people of varying ages, income levels, and demographics. They can alleviate congestion and reduce the requirement for brand-new construction. On the other hand, it’s not without its flaws. Permits for constructing an ADU can be difficult to come by and costly. If you had to choose, what would you say? Is it necessary for you to move into an accessory dwelling unit? What follows is a more in-depth look at the advantages and disadvantages of this housing option.

    What is an Accessory Dwelling Unit? Why Would You Want One?

    ADUs, or accessory dwelling units, are often added to a primary residence to provide additional living space for a growing family or to accommodate regular overnight guests. These days, more and more Californians are turning to accessory dwelling units (ADUs) as an alternative to constructing a whole new home.

    The ability to age in place, rental income, guest quarters, or room for an extended family are just a few of the many upsides of constructing an ADU on your property. The addition of an ADU might increase the market value of your home. It is recommended to consult a professional builder about the steps involved in acquiring a building permit in California for the installation of an ADU.

    Gains From Renting Out a Property

    One of the most popular reasons to purchase a secondary dwelling unit is to improve rental income. Renting out a secondary dwelling unit might help you cover some or all of your monthly housing costs, such as your mortgage, tax bill, and insurance premium. It’s possible that this may allow you to save enough for a trip or for some much-needed house maintenance. During economic downturns, rental income can also provide much-needed stability. Because an ADU is its own unit, your renters will have no trouble striking off on their own.

    Adding an ADU to your property may or may not be permitted, depending on local zoning regulations. As soon as you receive approval, you may immediately begin taking advantage of all an ADU has to offer.

    Additional Space for Visitors or Relatives

    Attached dwelling units (ADUs) are a great way to boost your home’s resale value and provide a host of benefits to its owners. One advantage of an ADU is the additional room it provides for a living. Thanks to ADUs, many families now have room for guests and extended relatives. Those who live in remote places or who often host guests from far away might benefit greatly from this. ADUs are ideal for elderly parents or adult children who want to maintain their independence. A detached accessory dwelling unit (ADU) can provide the extra living space required for hosting out-of-town guests or accommodating extended family.

    Extra Room

    Known as ADUs (accessory dwelling units), these extra structures are becoming popular and offer several benefits to their owners. Extra space for storing things is a major perk of an ADU. A detached accessory dwelling unit (DADU) can provide extra welcome room for storing seasonal items, sports equipment, Christmas decorations, and other items that are only required sometimes. Moreover, if you don’t want to get rid of things like old furniture or baby items that you never use, an ADU is a great location to keep them. If you’re considering constructing an ADU, you may put the additional space to good use by utilizing it as a storage shed.

    Working From Home

    More individuals are opting to work remotely in today’s market. This setup is highly regarded by a large number of individuals since it allows them greater freedom and control over their daily work routines. However, it might be difficult to concentrate when working from home due to the lack of human interaction and the presence of several potential distractions. In order to have a place to work while yet being close to home, you may construct an ADU. It is possible to get an ADU that has a private office with all the amenities of a modern workplace. Accessory dwelling units can be designed to blend in with the aesthetic of the main house. Therefore, it is a perfect fit for your home and fulfills your requirements. If you need a quiet place to work or want to save gas money by taking the shortest route, an ADU may be the ideal choice for you.

    The Price of an ADU in California

    An average detached accessory dwelling unit in California may be built for around $150,000. This includes money spent on things like permits and supplies as well as wages and other expenses. However, the total cost may vary considerably based on factors such as the unit’s size, complexity, and location. Many homeowners opt to construct their own ADUs as a means of financial savings. Loans from financial institutions, such as banks and credit unions, as well as home equity loans and private loans, are all viable options for financing a project.

    You should research your options and compare bids from many service providers before making a final choice. You may keep your ADU project inside your set budget by researching pricing and preparing beforehand.

    The Building Method

    Building accessory housing units in California requires a permit from the local planning agency. The application must include crucial zoning details and detailed blueprints of the proposed unit. The planning commission will review the proposal and decide whether or not to grant permission. Get a building permit from city hall if your application is approved. Once the required permissions are in place, construction may begin. From start to finish, the process typically takes between six and eight months.

    Before making the decision to purchase an ADU, homeowners should research the relevant legislation. ADUs in California must be either attached to or detached from the primary dwelling. Furthermore, only one ADU of up to 1,200 square feet in size may be built on any one parcel of land.

    A comparable cap is placed on the total number of occupants in an ADU at any given time. One example is that inhabitants must be related to each other in some way, such as by a parent-child relationship, marriage, or domestic partnership. Finally, there are setback requirements that must be met while building an ADU.

    Depending on the property’s location, these minimum distances might be as low as three feet and as high as 10 feet. Prospective homeowners should think long and hard about whether or not an ADU is right for them in light of all of these regulations.


    The use of ADUs is on the rise in the Golden State. Micro-apartments have grown in popularity due to the practicality of sharing a dwelling with a close friend, cousin, or even a faraway coworker.
