> The issue isn't the supply of new housing, it is the cost of building new housing.

I fail to see the distinction. The cost barriers (most of which are legal/zoning related) reduce quantity supplied.

I don't believe it costs 2 million in materials or labor to make a condo in California.

I think tackling zoning is a good example of addressing fundamental cost issues instead of supply.

Cities actually building or mandating new 2 million condos for the poor would be an example of trying to fix supply without fixing the cost issue (which happens).

In general, reduction of regulation is needed to decrease cost.

I have family that just built a home in a county without zoning or building codes, and I can assure you it was quite cheap.
