Yes, I'm aware that moving out of city limits tends to relax the building code & zoning a little bit. Planning to do that eventually.

But it was just an example of a thing that can contribute to rising construction/housing costs. I don't think it's particularly helpful to tell a young person "whoopsie, we could have built housing for you, but thanks to the last 10 recent code updates, the house is now 2x as expensive and you can't afford it".
