> How many of the units are earmarked for 'affordable' housing

This one is called IZ (inclusive zoning) and is an extremely popular weapon with SF and Portland "left-NIMBYs". They know if the number is set too high, it will both make them look good and cancel literally every housing project in the pipeline (as noone can afford to build it anymore), so set it too high they have, and so their project pipeline collapsed.

When it's used at low levels it can work, but only if you accept that it fundamentally makes the project more expensive, which means the more "luxury" projects are more likely to survive, and means the cost of the market-rate units goes up.
