KEEP IN TOUCH WITH FAMILY

ADU in Atherton, CA

As  California (as well as the rest of the world) becomes more urbanized , families find it more and more difficult to live close to one another. Families that want to maintain close ties with their loved ones may find this to be a considerable challenge. However, ADUs (accessory dwelling units) might offer a solution. ADUs can be located next to or part of the main house. They could be used by a young adult going out on their own, a guest house, or an aging relative. The best part is that they enable families to live close together without invading their privacy or individuality.

Mother-in-law suitesguest houses, and rental properties are typical applications for ADUs. They can also be quite helpful for families who want to stay in their existing location but need extra, flexible space for long-term living. For instance, a family with young children might use an ADU as a homeschool,  or a professional working fro home as a dedicated office. An ADU can be a great solution for empty-nesters who want to downsize but still have room for out-of-town guests. ADUs are the ideal solution for families who require additional space. For instance, an ADU may be transformed into a mom’s hideaway or “she-shed.” Or you might make it a “man cave” where dad can take it easy. For families in ADU Building Guidelines for Atherton, CA, who wish to stay in touch, ADUs are a popular choice.
