The part that wont work about this is it targets the wrong sector of the housing market. Most of the rules you suggest would apply to luxury properties/vacation rentals/etc. Even if the owner were to sell the property, it wouldn't suddenly become affordable. These are the most "visible" homes, but they are a tiny minority of the housing market. The problem as I see it is government regulation. There was a thread on Reddit from a LA property developer that explained why only luxury apartment buildings ever get built. Long story short is there was so much red tape, regulation, etc that building anything but expensive high rise units was unprofitable. I heard somewhere that for the average home in California, you're paying something like a 50-80k premium because of red tape and regulations. The solution isn't to add more rules and regulations, but rather to take them away. The way we are going to get more affordable housing isn't through a program where 10% of a high rise's units are "affordable", but by actually making affordable housing profitable. If a developer can build an "affordable" property and make money on it, we will see more of them.
