What I know is mostly from Seattle, but applies in most places:

- Usage Restriction. Seattle is famous for having the highest percentage of land zone exclusively for single family housing. This puts a hard limit to how much can be built.

- Parking Minimum. These can drive construction costs a lot, so much that a lot of projects can't be build profitably.

- Endless "Environmental" review processes. While these do sound good in theory, they have (at least in Seattle) very rarely been used to actually protect the environment. They're typically used by NIMBYs to slow down and delay projects forever so that developers abandon.

There is a lot more, but those are some of the main things people talk about when they point to "zoning regulations".

Thankfully those are mostly going away. Single family zoning is no longer a thing. Parking minima are gone. Environmental reviews are more streamlined.

We still get people being like, "No my neighborhood character is changing!" But thankfully most of them are drowned out by people asking for up zoning and more housing.
