This recent article by Bloomberg CityLab, about "how California set off a backyard apartment boom," has some interesting stats about the extent in which accessory dwelling units (ADUs) are quickly being adopted and delivered across the state.

For one, a majority (87%) of jurisdictions have enacted at least one ordinance related to ADUs, though many have several. These policies might include everything from by-right zoning to some form of financial assistance if you build. Here is a graph showing the cities and counties that have created ADU ordinances since 2013:

All of this has translated into housing supply. In 2019, California homeowners brought over 12,000 accessory dwelling units to the market (based on permits issued). Though a relatively small quantity based on the state's overall housing deficit, this number is surely growing thanks to policies and programs, like this one here, that are working to remove the barriers to building.

The city of Los Angeles has taken an interesting approach to accessory dwelling units (what we generally call laneway or garden suites here in Toronto). In an effort to streamline the approvals process and bolster the supply of housing in the city, they've gone out and pre-approved a series of "standard plans" that you can quickly implement on your property. The idea here is that all of their approved plans have already been checked for compliance with the various building codes. So those reviews don't need to happen before a permit can be issued (though the building department would still need to review any site-specific conditions).

What that means is that if you're in the market for, say, a one-storey, one-bedroom ADU at around 450 sf, you can simply scroll through their list and find the one you like the most. Here is one that fits this criteria by Design, Bitches (I just wanted to mention this firm name). The potential downside of this approach is that it could encourage less architectural experimentation. On the flipside, many of their approved designs are really nice and so maybe it's a boon for those who are lacking in good taste. Either way, if you want to encourage more of something, the way to do that is to reduce friction.

To start to give you a sense of how meaningful this could become, the city of Los Angeles received 1,980 applications for ADU construction back in 2017. This is the year in which the state changed its regulations so that ADUs were no longer prohibited in some municipalities (I don't know all of the specifics truthfully). Last year, LA saw 5,374 applications and I suspect the number will be even higher this year. Should other cities look at pre-approving certain designs? And could this be an approach used for even larger building typologies? Speed is good.
