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.
Two generations of the Whitley family found a solution to both their housing dilemmas when Carrie and Sterling were approved as the first residents of Monterey Bay Habitat for Humanity’s My House My Home program. The big idea behind the innovative My House My Home program is to build ADUs to assist low income senior homeowners who might be vulnerable to housing instability because they are living on a fixed income.
A few years ago, Diane Owen was sharing a house in Denver, CO with her daughter Mara, and Mara’s partner Andrew. Diane’s one bedroom, one bathroom multi-generational household also included three dogs, so it was a full house! Diane had been living with Mara and Andrew for three years and they got along really well, but there were moments that a little more wiggle room would be nice.
When Scott Drake bought his father Walt’s property in Decatur, GA they struck a deal. They’d build a carriage house for Walt so that he could remain on the property and have Scott and his wife and kids move into Walt’s old house.
Asmund and Jenny had been considering building an ADU for quite a while and finally decided to take the plunge at the end of 2016. They were drawn by the potential for passive income, the need for more space for their growing family and guests, and they wanted to lock in the SDC fee waiver benefit before its scheduled expiration. They were particularly drawn to the short–term rental model to maintain the most flexibility.
Over the course of a recent Saturday afternoon open house, more than 40 neighbors, friends and family stopped in to see a new apartment on Sherburne Avenue in the Hamline-Midway neighborhood and congratulate the owners, Eric and Chrissi Larsen, on its completion.

This past weekend Lina Menard, one of our editors and the coordinator of the ADU Case Studies Project, taught an ADU Design Class through Portland Community College. The fourteen students brought a variety of project ideas, including everything from garage and basement conversions to backyard cottages, additions, and renovation of a workshop.
This week’s ADU Case Study was written and contributed by Deborah Kelly, the owner of an ADU called Mossy Cobbles. Deborah worked with her son, Justin S. Kelly, who is an architect and engineer, to design the cottage for Deborah’s mother to occupy when she lived in Portland for half the year. It was constructed by the next door neighbor, Tony Kikes with hardscaping by another friend and neighbor, Steve Carruthers. The cottage is now available as a short-term rental.
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.
Major design considerations for Natalie and Justin Strom included creating a feeling that their ADU is more like a single family home than an ADU and fitting the ADU into the aesthetic of the traditional neighborhood while bringing in modern elements in the interior. It was also important to Justin and Natalie that the design be flexible enough to allow for multiple use and that they utilize sustainable and energy efficient building materials and techniques.

The key factor that convinced Al and Shannon to build their own garage apartment was increasing their housing flexibility. They built the ADU first with the plan to eventually build a house on the front portion of the lot which would allow them the option of using the ADU as a potential income property. The ADU was constructed in 2013 and the primary dwelling in 2015.
Because Keith & Stephanie’s home is located in an historic district and their garage was considered a contributing structure, they had a few additional design considerations.

What convinced Sylvia and her wife Martha to create an ADU on their own double lot was the desire to help Marion, an elderly friend who lived in Florida who needed daily assistance. So the three of them agreed that the most practical plan was for Sylvia and Martha to build an attached apartment so that Marion could live with them.

As Ray and Natalie explored design criteria for their ADU, they landed on a design that allowed them to have a living space above and a shop below.
To create their ADU, Lisa and Patrick tore their 2-car garage down completely and built from the ground up with a brand new foundation. But, of course, this happened in typical Brad Bloom style, meaning that as he deconstructed the garage, he salvaged everything he possibility could for reuse in the new space.
