That’s the entire point of HOAs though; so that the city can offload those costs onto another organization AND collect the same revenue they would otherwise. At least where I live, it’s well understood among developers that the zoning and permitting process is how this is enforced.

The real, completely arbitrary thing that makes housing expensive is zoning. There is research on this. Zoning, especially in the long term, has enormous effects, including on things seemingly unrelated such as reducing construction productivity, reducing competition among construction firms (fewer contractors) and reducing housing supply (supply vs demand).

I think people generally don’t appreciate how restrictive zoning effectively is. It’s not just what you can build, but how big it is, layout things, and can even reach into aesthetics etc.
