I'm curious to see how Austin will do in the near future by that same metric. More people can afford a place that will let them pay rent, although now at least some of those people will be living in someone else's basement or garage. These may not be very nice places to live, but they may be all some people can afford.
They've also removed the regulation requiring a second way out of a burning 5 story building. Austin faces an increasing number of red flag warnings and has the 5th highest wildfire risk in the US. It remains to be seen what removing that second exit route will cost in the charred corpses of families.
Austin is also cutting corners on permitting which is great news if that was all needless red tape that can be rushed or skipped without cost, but if new apartments built today are (or soon become) deathtraps due to lax code enforcement that could be a major problem down the road.
Austin has already lowered rents which is great, but hopefully it was also done right and it doesn't result in more people being forced into substandard housing or increased deaths. As long as it doesn't, other cities should look into trying some of the same things Austin has done.
