U.S. — Listings for multigenerational homes in the United States received about 14% more page views per listing than typical home listings in 2024 and sold for roughly 22% more per square foot, according to realtor.com data. The figures reflect a rise in households where at least three generations live together under one roof.

In 2024, 4 million owner-occupied homes in the U.S. included a parent, a child, and a grandparent living together. The median sales price for a home in the U.S. is about $400,000.

"We see that there are more multigenerational households in the U.S." said Hannah Jones, senior economic research analyst at realtor.com. "We see that multigenerational listings are becoming more popular."

Such listings are most common in Western states, particularly California. In the South and Midwest, multigenerational homes cost even more per square foot than on the West Coast, where they are more common.

Homebuilders have responded with floor plans that incorporate secondary dwelling units, which often include a private entrance, living room, kitchenette, and a washer and dryer. Sharing a mortgage among multiple households can make homeownership more affordable for the participants.

"We like to refer to it as a home within a home," said Jeremy Parness, a regional president at Lennar, one of the country's largest homebuilders. "I like to say two homes, one payment. That's the way to think about it."

Andrea Wolverton, a nurse, moved into her parents' home in the Portland suburbs with her 3-year-old son, Theo, in 2023 after separating from her husband. While she worked 12-hour shifts, her parents handled her son's bedtime, preschool drop-off and pick-up, and cooking. She paid rent to her parents, which helped accelerate their retirement timeline.

"It was hard to pay all the bills, pay my mortgage, all those things, and be able to just feel like I could be present for my kid and everything." Wolverton said. "This makes so much sense. Why don't more people do it?"

A few months ago, Wolverton moved out of her parents' home and into a rental home with her partner and their son. When she eventually purchases a home, she plans to choose one with enough space for her parents to live with her.
