Supply is 100% constrained by regulation. SF (and every other city) requires a permit to build. Go try to get a permit to build something in sf. I guarantee you’ll find a hundred different blockers including if any of your neighbors would like to object. (They will)

Wrong, sorry. The construction costs have exploded in recent years for a number of reasons, not least of which is a constraint on construction supplies. This problem actually exists in more places than SF, and it will have varying levels of contributing factors depending on where you are, but as much as the internet loves to cry NIMBY, it’s simply not the primary factor here.

You may need a permit to build, but it’s not nearly as impossible as Reddit would have you think.

Awesome, I want to build a 6 story apartment building in 20 random locations in 20 random cities.

What are my odds of hitting at least 10 places where I'd get a permit?

If you think regulation is the only constraint on supply, you're wrong.

Let's get rid of the regulations then so:

A. There is no more debate about it

B. Suppliers are motivated to catch up to where the supply chain needs to be at.
