Bertha and her son John talked about someday buying a house with a mother-in-law suite. “Then one day someone came along and wanted my house, so I up and sold it,” she explains. “But that left me homeless. I asked John if I could build a small house in his backyard and he agreed.”
CREATIVE THINKING: A detached bedroom is a permanent, accessory structure that, unlike ADUs, lacks a kitchen. But that’s what makes these cabin-like homes more affordable to build than many ADUs and even tiny houses.
WHAT’S INSIDE: Bertha’s home contains a sleeping and living area and a full bathroom. “I paid for the little house and it’s on my son’s property. So I figured, if I’m cooking I can do it at my son’s house,” she says. (Her laundry is also done at his house.)
REAL LIFE: “Having access to my son’s house makes it livable. Otherwise, I personally would not be happy. It’s very comforting to know that John is close by. Hopefully this will be my home forever.”

While not technically ADUs, tiny houses can serve similar purposes
Because tiny houses — such as the 100-square-foot- "Lucky Penny," pictured — are build on a trailer with wheels rather than on a fixed foundation, they are typically classified as recreational vehicles (RVs) rather than permanent residences. Although tiny homes are usually smaller than 400 square feet, many of them do contain a kitchen and bathroom.
