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.
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.
The 24-hour period from the afternoon of Sunday, June 29th- afternoon Monday, June 30th, 2019, was an important day for ADUs.
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.
This post details some findings about ADU permit trends in Portland.
First, we’ll start with the big picture. Here’s the latest data on the number of permits issued by the City of Portland for ADUs from 2000-2018. In 2017, 588 permits were issued. In 2018, 660 were issued. This is a total of 1248 ADU permits issued in 2017 and 2018.
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.

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.
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.
New research from Canada finds that ADUs and garden suites can function as voluntary version of affordable housing — with some important caveats.

Portland is leading the pack with ADU development nationally. Data provided by the City of Portland shows the rate of ADU permits issued from 2010-2016. In 2016, 615 permits were issued, 20 times the average number of permits issues each year before Portland’s SDC waiver in 2010.

It’s not intuitive, but prohibiting short-term rentals in ADUs won’t necessarily lead to a bigger supply of long-term residential housing. This post includes new data about the number of ADUs and short-term rentals in Portland, and the longevity of short-term rental listings.
Portland is probably America’s most ADU-friendly city. Portland has eliminated many of the Barriers to ADU Development in two big ways: by relaxing regulation and by offering generous financial incentives.
I didn’t realize that there were so many creative ways to make an ADU. Here are the 10 most interesting examples of Creative ADU Types I’ve encountered.

Houston, Texas has a long tradition of accessory dwelling units. It also has a unique lack of zoning rules. Could it be the next hotbed of ADU creativity?
Collected research about accessory dwelling units (AKA granny flats, laneway houses, in-law units, etc) suggests they have many potential benefits, and two common arguments “against” are unsupported.
ADUs are especially promising as environmentally sensitive and affordable housing, and this potential should be investigated in detail.
Government rules strongly limit the development of ADUs, but they are not the only factor.
If the “grassroots” nature of their development is properly understood, ADUs have a lot of potential to address affordable housing needs.
Will building an ADU raise your property taxes? Very likely yes. Is that a good thing for the community?
Older persons are expected to benefit from ADUs. Is this happening now, and will it happen more in the future?
The single biggest and most specific fear mentioned by ADU opponents is loss of street parking. Is there any evidence on this?
Many cities may claim to allow ADUs in their code, but in fact, their regulations prevent citizens from actually building them. In San Francisco’s case, there are ‘discretionary reviews’ and other … Continue reading

It may seem odd to ask whether a housing form actually provides housing, but it’s a key premise in civic debates about accessory dwelling units.
ADUs are a really unusual form of development. This post goes over their special qualities, and explains why a lot of “debate” about ADUs is so repetitive.
