I assume this (and really any extra mandates for landlords) is going to drive more small/private landlords out of the business, and that won't necessarily increase housing availability on its own, but will instead be filled by larger corporate landlords that can afford to deal with administrative work required. As I've gotten older, I've found small landlords to be where you can find the best experience (but also maybe the worst, it's more variable), having just corporate landlords feels like you'll always get a shittier place (minimal work done) for market rates.
Definitely a YMMV situation, with corporate landlords when I've called them out for breaking the law they usually backpedal. Mom and pop landlords in my experience always attempt to skirt around laws and just out right down respect them.
The golden experience to me has always been small businesses landlords who aren't quite corporate yet, might own a building or two, but generally small in the grand scheme of things. They ofc eventually sell out to the corporate ownership anyways.
