The categorical elimination of single-family zoning along with any building envelope restrictions that would make as-of-right 3-flats uneconomical.

It's might actually be easier to win the economics battle by chipping away at restrictions on taller buildings. The builders in my area are copy/pasting a 3-flat design all over the place but it requires bargain-basement land prices (literally building on former toxic waste dumps) or money from the township because 3-flats make you have to build wide.

  • The muni I live in is very constrained (we're just 4 square miles, right on the border of the west side of Chicago) and our land is overwhelmingly SFZ, so most of the ballgame is getting SFZ lots opened up. The emerging consensus is towards "missing middle" housing, which is 2-40 units (but really, a medium term sweet spot in the teens), where you're talking about buildings spanning multiple lots.

    That very little can economically be built on existing SFZ lots even with relaxed zoning is actually a feature, not a bug, for getting this done. People want change to be slow. At least to begin with, it's better strategically if it takes a couple years and gradual tweaking to make lots of building happen.

Rather than the complete elimination of single family (and by extension even larger lots) I feel like it ought to follow something resembling an iterated 80/20 rule out to huge rural lots at the far end. Notice that this would imply a plurality of the land being zoned for the highest density at any given time.

The thing that really kills density in most cases is the height restrictions. A lot of the upzoning in my area has resulted in ugly, wall-to-wall low-single-digit floor count buildings with near zero setback. It's better than single family but it isn't particularly dense and it's a huge step backwards aesthetically.

That would be an outstanding outcome! Is this just for Oak Park, or beyond?

  • You'd hope that Oak Park, Evanston, Wilmette, and then Berwyn and Schaumburg could get this done, and then your next step would be either Chicago (tough because of aldermanic structure) or statewide, the way California did. Either way: you start in one municipality and work from there.

    It helps that zoning matters more in Oak Park (and Evanston) than almost anywhere else in Chicagoland.

    • There is no way you get Wilmette to change zoning. They've fought with Small Cheval about the size of their sign for like 9 months. I doubt you'd get any village in the NT district to rezone - the Optima project was pulling teeth, everyone is worried about overcrowding NT, which as a single HS is pretty packed now
