Naturally, some abutters weren't happy about this (worried about competition for on-street parking, impact on home values, having people next door who, gasp, don't make a lot of money) and were trying to apply some pressure to get changes but I don't think they were successful. For whatever reason, there has been very limited coverage of this that I can find in the press.
If anyone else knows whether changes made to multifamily zoning by Seattle's DPD this summer impacts what Calhoun Properties does, I would _love_ to hear about it.
I'm trying to figure out whether I think "congregate workforce housing" will ever produce interesting results through google. Maybe I'll just check in with that search every few months and see what happens. Unfortunately, this is one of those things that can happen everywhere in mass quantities and _still_ not get covered by anyone, so not being able to find anything is not evidence that it isn't happening.
