Family households consisting of three or more generations, or “multigenerational households,” have become increasingly popular in recent years. According to the most recent Census, approximately 4.4 million American homes had three generations or more living under one roof in 2010, a 15% increase from two years earlier. This is 5.6% of the total of 76.4 million U.S. households with more than one person.

There are many reasons for this trend. The recent recession caused many adult children to return home after college, either because they weren’t able to get jobs that would cover rent, or they wanted to save up to buy homes of their own. According to Pew Institute research, the share of the U.S. population aged 25 to 34 living in their parent’s home increased to 23.6% in 2012. That’s up from 18.7% in 2007 and 11% in 1980.

For many ethnic and immigrant groups, multiple generations of a family living together is a common cultural custom.

Multigenerational households also form so that grandparents can help take care of their grandchildren, and as they age, their children can care for them. This type of arrangement can ease financial burdens as well, with several generations contributing to the mortgage payment and not having to incur the expenses of childcare, retirement housing or professional care-giving environments.

Home builders and remodelers are building and renovating homes to meet the needs of multigenerational households. These designs allow many generations of the same family to live together under one roof yet have private areas as well as combined living space.

Features of multigenerational home plans can include in-law suites within the main home with separate areas for independent living. These often have kitchenettes and en suite bathrooms, and sometimes private entrances from the street. They frequently include “universal design” features, which focus on maximum usability by people of all ages and abilities. Examples include walk-in showers, smooth flooring transitions, and cabinets with pull-out drawers.

Building professionals who have earned the National Association of Home Builders’ Certified Aging-in-Place Specialist (CAPS) designation have received training on how to build or renovate a home so that the occupants can live in the home safely, independently and comfortably, regardless of their age or ability level. They have been taught the strategies and techniques for designing and building aesthetically pleasing, barrier-free living environments. While most CAPS professionals are remodelers, an increasing number are general contractors, designers, architects, and health care professionals.
