It’s going to take a SCOTUS decision overturning Ambler vs Euclid in my opinion.
We certainly will not see zoning reform until the Boomers die.
Hate to be the bearer of bad news here, but the boomers will never die. Gen X will become the new boomers, and then the millennials after them. Individual people die, but interests stay the same.
Case in point: my parents. Built a house in 1988 and they still live there. Two people in 3500 square feet. Four bathrooms and five bedrooms. Meanwhile, you need a family income of 3x the median to rent a townhouse 1/3rd the size nearby.
This is beyond ridiculous and it’s totally unsustainable.
