In March, a California company called Adaptive Modular Solutions rebranded itself with a new name: CRATE Modular, Inc. “We make housing and school buildings out of recycled shipping containers,” the company’s website states.

Gov. Gavin Newsom has just signed a stack of new laws that will enable these containers to be dropped into the back yard of any single-family home, anywhere in California.

As I wrote in last Sunday’s column, one of the new laws, Assembly Bill 68, forces cities to allow two accessory dwelling units, or ADUs, for a total of three residences on one single-family lot.

A number of readers emailed to ask whether this applies to communities with homeowners associations (HOAs) that ban or restrict ADUs. Yes, it does.

A separate law, Assembly Bill 670, makes “any covenant, condition or restriction” that “effectively prohibits or unreasonably restricts the construction or use of an accessory dwelling unit or junior accessory dwelling unit on a lot zoned for single-family residential use” — are you ready? — “void and unenforceable.”

Newsom signed AB670 on Aug. 30, and later signed other bills to expand ADU construction over a city’s objections. The governor revoked local control using a broken-up jigsaw puzzle of laws. With all the pieces scattered around the table, and on different tables during different months, it wasn’t easy to see the whole picture.

We can see it now. It’s a portrait of the intentional destruction of single-family zoning in California.

One of the puzzle pieces, AB881, requires “ministerial approval” of an ADU, which means the local government generally can’t refuse to approve it. The same law blocks local agencies from placing an owner-occupancy requirement on the sites for five years, enabling these home-triplexes to be operated from a distance as if they were hotels or apartments.

The author of AB881 said it would address “ambiguities in the ADU statute that can slow or block the construction of these units.” There’s nothing ambiguous about local concern over parking. In some neighborhoods, where street parking is already hard to find, doubling or tripling density will have an extremely negative impact.

And there’s no help offered by another one of the jigsaw-piece housing bills, Senate Bill 13. It provides that when a garage, carport or covered parking structure is demolished to construct an ADU or is converted into one, a local agency “shall not require that those off-street parking spaces be replaced.”

So while every single-family lot in California may potentially triple in density, total parking spaces could be reduced by half. Meanwhile, Newsom is taking revenue from the gas tax increase away from road-widening projects so he can spend it on rail projects. Your state government believes that driving is an unacceptable activity and should be strongly discouraged. You may ride a scooter.

I’ll bet you never thought, when Sacramento politicians promised to do something about housing, that what they planned to do was turn quiet streets of single-family homes into teeming low-rise tenements lined with double-parked cars.

But that’s what they’ve done. And it won’t take long, either. Thanks to companies like CRATE Modular, Inc., a pre-fab shipping container home can be dropped into a yard tomorrow.

There is nothing to prevent corporations from buying up single-family homes and turning them into rental triplexes or Airbnb-style units. Young Californians trying to buy a home will be competing against all-cash offers from investors.

California is indeed a cautionary tale for the nation

Governor Newsom should deliver theme park guidelines ASAP Instead of pursuing density, California could encourage developments in outlying areas that would become affordable new communities. But that’s not Newsom’s vision. Young families may want a home with a yard and fruit trees. They’ll get a crate and a scooter, and cranky neighbors.

And more traffic. Newsom also signed laws to grant density bonuses (AB1763) and “streamlined” approvals for low-income or affordable housing (SB330).

Other laws signed by Newsom require cities and counties to report to the state an inventory of “surplus lands” to be included in a state database and in local progress reports on housing (AB1255, SB6, AB1486).

These laws could threaten the existence of a local treasure, the Pierce College farm in Woodland Hills. “Surplus” is the word that’s been used to slice off pieces of it for development in the past. We’ll be watching.
