10 Ways Your ADU Can Support Your Retirement

As I’ve interviewed homeowners, designers, and builders about ADUs over the past several years, one thing that has impressed me is how many people are using an ADU as part of their retirement plan. ADUs can provide housing flexibility, additional income, one-floor living to age-in-place, proximity to family members and caretakers, or even just a place to call home when traveling.

Evelyn Brom’s ADU: Another House for the Other Street

In 1995, Evelyn Brown purchased her property in Seattle, WA and immediately imagined building a second house on it. The property was a through-lot, meaning that it spanned the distance between two streets. Her house, at one end of the property, fronted on one street and her garage, on the other end of the property, fronted the other street. Twenty years later the city caught up with Evelyn’s vision and she now lives in an ADU she has plenty of time to dream about.

Lisa Lonstron’s Other House: A Rooming House

While interviewing more than 60 ADU Homeowners for the ADU Case Studies project, I came across several different ways that people use their ADUs. I heard time and time again that ADUs provide housing flexibility and give their owners additional rental options as their life circumstances change. ADU owners can Rent One, Both, or Neither. But I’d always assumed that when an owner decided to rent out either their house or ADU they’d be renting it to a single household. Then I got to talking to Lisa Lonstron who lives in her basement ADU. Her other house – the one she lived in before she turned her basement into her apartment – is a rooming house.

Bob & Adrienne Stacey’s Future ADU: Well-Planned Beforehand

Adrienne and Bob developed a creative multi-generational housing solution that will allow them to share space with their daughter, son-in-law, and grandkids, while operating a home-based business.

However, when Adrienne retires from teaching, the plan is to renovate the addition to make it officially an ADU by adding a kitchen. In the meantime, they knew that as long as they were sharing the house with their family members, it would be no problem to have the addition dependent upon the kitchen in the primary dwelling.
