Carrie & Sterling Whitley’s ADU: Housing Stability for Two Generations
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.
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.
Diane Owen’s ADU: A Carriage House at My Daughter’s Place
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.
Bertha’s ADU: A Tiny Cottage in My Son’s Backyard
Bertha and her son John had always been fairly close, but they lived their separate lives in different parts of St Petersburg, Florida.

ADU Advocates’ Unsanctioned Guidance for Oregon Cities Updating Local ADU Regulations by January, 2020 to Comply with HB 2001 Statute
Two of the most common “poison pills” in ADU standards will be prohibited statewide in Oregon beginning in January, 2020, making earlier ADU legislation significantly more effective.
Oregon House Bill 2001 (HB 2001) was signed into law on August 8th, 2019. While HB 2001 rightly claimed headlines for expanding missing middle housing options, it also included some specific requirements for ADUs.
Consider Going All-Electric For Your ADU
Natural Gas, or methane has been promoted both as a ‘Clean Fuel’ or a ‘Bridge Fuel’ in various circles, both locally and nationally during this time of climate crisis. Concurrently, the IPCC has called for a far more rapid decline in the use of fossil fuel, more rapid scaling up of renewable energy taking advantage of the falling costs, and avoiding a lock-in of high-carbon infrastructure.
Perspective: How to make accessory dwelling units affordable
ADU financing could — and perhaps should — be a lot more like commercial real estate financing, only with a human touch. A guest post by Roger A. Gins.
ADU Legislative Initiatives- History in the Making (Part III)
Several significant bills passed through the legislative process in California last week. This legislation that passed in CA is major and will help usher ADUs out of the dark ages.
ADU Legislative Initiatives- History in the Making (Part II)
As reviewed in my first post on this topical thread, significant and progressive legislative and regulatory ADU code overhauls are occuring at quickening pace in jurisdictions up and down the west coast. I’ve been tracking ADU regulatory reform fairly closely for a decade, and there hasn’t ever been a time period where ADUs have been gaining as much national traction as they are now.

In the future, urban planners will point to that day as a signature moment for an era of deregulation and liberalization of codes for ADUs.
ADU Development Costs Keep Going Up
I’ve updated an extensive post about ADU development costs here. These updates are based new cost numbers that just came in from the upcoming 2019 ADU Tour in Portland, which serves as a repository of current and active primary source data for cost estimates. It turns out that current primary source data is critical when it comes to talking about the costs of ADUs, because the development cost numbers here keep escalating rapidly.
2019 is the Year of ADU Financing Innovation
Financing ADUs has remained a major challenge. But, in the future, 2019 will always be thought of as the year of ADU financing innovation. On April 29th, Portland State University convened a meeting in Washington, D.C to help flesh out some of the innovative programs that are being developed to finance ADUs.

ADU Rental Income Can Be Used to Qualify Borrowers to Purchase on HomeReady Loans
A HomeReady Mortgage is a Fannie Mae, first-time home buyer loan program, with minimum down payment requirements, and some very particular underwriting characteristics. When a borrower is purchasing a single-unit primary residence with a 3% minimum down payment and there is an ADU present, 75% of the potential rents from the ADU can be used to qualify.
Asmund & Jenny’s ADU
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.
ADU Legislative Initiatives Abound
SDC Waiver, Residential Infill Project, Oregon and California state legislative updates….
There are significant ADU legislative initiatives underway in California, Porltand, and Oregon at large. Each of these legislative efforts have national signficance.

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 wasn’t just any apartment — it was the first accessory-dwelling unit to be built under St. Paul’s 2016 accessory-dwelling-unit ordinance.

Accessory Dwelling Units: A Tale of Two Cities
Guest post by Mark Thieroff from St. Paul, MN
About five years ago, interest in accessory dwelling units had reached a critical mass in Minneapolis and St. Paul. ADUs were seen by proponents as a way to increase housing diversity and flexibility and add density in residential neighborhoods. But Minneapolis and St. Paul ended up taking very different approaches and, consequently, have seen markedly different results.
Now Collecting ADU Stories from Across America
Calling ADU Owners, Dwellers, Designers, and Builders from across America to share ADU stories for an exciting new project with AARP. The many benefits of ADUs – especially for multigenerational families – have caught the attention of AARP. They’ve commissioned a publication about ADUs, which will feature half a dozen case studies of ADUs with various configurations and uses. If you’re an ADU owner, dweller, designer, builder, or city planner and you believe you can help with this project, we’d love to hear from you! Just send me an email at accessorydwellings@gmail.com by February 28th, letting us know which of the four items above you’d like to assist with and send along a photo!
Backdoor Revolution- Part V- Why Vancouver, BC has Done a Lot of ADU-Related Things Right
Backdoor Revolution- The Definitive Guide to ADU Development is officially live!
…Vancouver, British Columbia is the North American leader in ADU development.
Among the most notable things that Vancouver has done is allowed both a secondary suite and a laneway home on the same property. Other US cities (Portland, Oregon, and Seattle, Washington) are considering this idea now, but to my knowledge, no US cities allow it yet.
Backdoor Revolution- Part IV- Top Ten Reasons Why Basement Conversion ADUs and Detached ADUs Are Like Chalk and Cheese
Basement ADUs and detached ADUs are totally different creatures.
As I began to write my book and researched ADUs of all types, I strongly considered writing a totally separate book about basement ADUs. I ultimately decided to concurrently capture basement ADUs along with other structural forms in the same ADU book.
Backdoor Revolution- Part III- Why Fostering ADUs is Different than Fostering other Housing Types
One of the reasons that ADUs are especially challenging to foster is that they are generally developed by average homeowners. No other housing type is commonly developed by non-professional developers.
If you don’t develop housing as a full-time profession, housing development is complicated and challenging. Actually, even if it IS a full-time profession, housing development is complicated and challenging.
Backdoor Revolution- Part II- Informal ADUs
One significant part of my book research was about informal ADUs. While permitted ADUs are still fairly rare, informal ADU (a.k.a. unpermitted ADUs) are not.
In writing Backdoor Revolution, I discovered that informal ADUs have a lot to teach us. The book is now available for pre-order on Amazon.
Backdoor Revolution – Part I – Origin
In 2013, I was observing ADU trends in the US by tracking Google News Alerts and reading academic articles….
I’ve spent the last 2.5 years on this book, and I am proud to finally release it to the world on January 23rd, 2018.
Building an ADU in L.A.- Part II (excerpt)
Between 2003-2016, an average of one hundred permitted ADUs had been developed each year in L.A.. While 100 ADUs a year is something, it’s certainly not a lot of housing for a city with a population of nearly four million people, and 1.4 million housing units. But, 2017 has entirely changed the landscape for ADUs in California at large. And, L.A. has done something that no one expected.
