"A study by the city controller found that a rate higher than 18 percent would likely slow housing production and reduce the amount of subsidies for affordable units."
"Even with the reduction, the levels are the highest concessions required for affordable housing among any major city in the United States."
"Peskin and Kim had pushed for a 24 percent requirement"
"To date, only two single-building projects without public subsidies have agreed to 25 percent affordable housing"

And none of that supports your exaggerated claim that Kim would prefer 100 units over 1,000 units. She's overseen the construction of the most housing in the city.

Even 18% (now 19%) can't be done at the majority of parcels in the city. I guess it's fine for SOMA, which has the highest land values and transit connectivity of any part of the city, but it doesn't work elsewhere.
