Thanks, I'm curious too. Incidentally it's not near Tucson but https://culdesac.com/ is in Tempe and looks really interesting for a car-free development.
It looks like stick-built / Type V / combustible construction, and they're giving everyone an e-bike, which is mildly scary given the trouble NYC is having with structure fires started by bike and scooter batteries.
Maybe I'm being too harsh, and new housing without included parking is major progress in Arizona. Thanks for sharing in any case!
