Sure, a contractor fixing fire or water damage can do so while residents live in their homes, but this is often a serious inconvenience to both the homeowner and the workers. Yes, hotels are available, but having an ADU allows you to have a more personal option on your own property.
And while we tend to think of this for our own needs, it might just as easily be for those same types of problems extended family and friends are experiencing. The ADU comes to the rescue.
Additionally, personal crises are just part of life. They happen, and often when they do, things are in upheaval. Having an accessory dwelling for family and friends can be extremely useful. Relative or friend going through family issues? Temporary tough spot financially? Struggling with surgical recovery? Just need someone around? An ADU can provide a solution and support to help overcome these issues.
Because the units are essentially fully functional stand-alone dwellings (kitchen, bath, separate entry, etc.), they can provide privacy and independence while still being connected to family and friends.
