Traditionally, the idea of in-law quarters has existed for thousands of years. In modern times, in-law quarters are making a comeback due to the necessity to consolidate time and money within families.

In-law quarters also come in the form of accessory living quarters, garage apartments, guesthouses, in-law units, mother-in-law quarters and studio apartments. Not all “in-law quarters” are reserved specifically for parents. Many people rent out these areas of their homes to supplement their income.

In-law quarters are usually a separate, preferably self-sufficient unit within the main house. This can be a simple remodeling of a bedroom and bath to accommodate a senior citizen’s needs. It can involve a second master suite with bedroom and bath. Ideally, in-law quarters can be a complex attached studio or a completely separate structure on the grounds of the main house.

Since the early 1900’s, Western society has moved away from multi-generational living. This has brought about the need for supervised living facilities and nursing homes for the senior citizens. This can be an expensive undertaking to consider within the family finances, as most insurance does not cover the expense of supervised care.

By the early 2000’s, the in-law quarter’s concept has begun resuming its practicality. Families have appreciated the many benefits the convenience brings. The inclusion of first generation parents living with the family helps financially as the income and expenses of two households can be consolidated and shared. This is much more expedient than maintaining two separate homes. In addition, senior citizens can continue to maintain their self-sufficiency and productivity while living within these arrangements.

With people living longer and healthier lives, the financial burdens of aging first generation parents has become a concern to most families. One in three of the baby boomers generation expects to include a parent moving in with them. This solution is becoming more popular as it also cuts down on time and worry for their parents.

Many new housing developments are including in-law quarters with separate suites for privacy. In 2008, a Senate bill passed that allows counties and cities to incorporate a second kitchen within single-family zoning developments.

In-law quarters are a comfortable way for families to stay together and for the third generation to have the benefit of the wisdom of the first generation. With the fast pace of modern life, having in-law quarters is a great option for liberating the family and sharing responsibilities.

Most Eastern cultures have always included in-law quarters in their family homes. The first generation always played an important role in the household. The Amish also have a tradition of moving their first generation into a smaller retirement quarters within the house. This is called a dawdi haus (daw-dee-hahs). As with the Eastern cultures, the parents were honored and participated as much or as little as appropriate.
