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.

Susan Moray’s ADU: Updating History in Ladd’s

Prior to applying for her permits, Susan paid for a design consultation meeting with the city of Portland and Jack brought preliminary sketches to explore various possibilities.

My architect, Jack, did his homework on what could be built, given these limitations and nailed down a design that was accepted on the first try with no changes. That was impressive. We were told by everyone we would never get what he wanted past city permit without going through design review but he did. -Susan Moray
