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.

“We were looking for a house with the potential for an ADU. This particular property is a corner lot and it has a backyard that was accessible from the side street.

The house they purchased in Portland’s Portsmouth neighborhood had potential for a basement ADU, with one major caveat: they didn’t have the code-required ceiling height of 6’-8” for a basement ADU.
Registration for the November 7th ADU Tour is now live; early bird sales end on October 24th. For those seeking design inspiration for small houses, the ADUs on this upcoming tour are exceptionally beautiful. Here’s a sneak preview of a few of some of them.
Joan and Rita’s carve-out ADU entailed creating a new entry on the north side of their house, and separating the ADU from the main house by building a wall in the former hallway leading to an existing full bath and the underutilized bedroom. The kitchen-dining-living area is the located in the front of the original house with a large bank of windows offering natural daylight and garden views, and the more private bed and bath areas are located toward the back.

Francie and Michael had three primary design criteria for their ADU. First, it had to be easy to maintain. Second, it had to be sustainable – both financially and environmentally. Finally, it had to be a pleasant space to call home.
The economics of a rentable space were appealing to Charlie and his partner Katharine, so when the couple built their own home they designed it to include an apartment. They’ve now included ADUs in two more homes they’ve built and they’re grateful that Portland’s policies now support the creation of ADUs.
Accessibility, sociability, rentability, and sustainability were driving factors for their design. The focus of the design was aging-in-place for both dwellings. A secondary goal was energy-efficiency so that the dwellings would be less expensive to heat and cool. They insulated the units with R-40 walls and an R-60 roof. Tight air sealing was also important and they ultimately achieved 2.2 Air Changes per Hour (ACH).
When Bonnie Dalton was younger, her grandma lived in a family owned ADU. So when Bonnie was older and her husband’s parents needed a little extra support, Bonnie naturally thought of creating an ADU at her own house.

Derin and Andra realized that if they were going to a do a full basement remodel, including a full seismic upgrade and new bedrooms, a bathroom, and recreation space, it would make sense to add a kitchen as well to create a fully self-contained unit. As they researched ADUs they were convinced to create one in their basement because it would create housing flexibility, enable them to have family close by, create community, and provide income potential.
John used a home equity line of credit (HELOC) and credit cards to turn his basement apartment into a permitted ADU. His primary design consideration was that he wanted the apartment to be a fully self-contained residence.
When Wally and Lara decided to get married, start a family, and start their own business, they decided they wanted a space of their own. However, they didn’t want their friends to have to have to move out, so Wally and Lara decided to convert the basement into a separate affordable living space.
