Why do you care if they do? Now you should have the right to demand that the chicken farm controls the smell, and otherwise isn't polluting, but stopping chicken farms completely is the wrong solution. The above includes assurance that fire and accidents will not spread.
Of course land in the bay is valuable enough that nobody will do what you suggest. However that is economics, it shouldn't be law.
I’ll assume there’s law controlling animal welfare, pollution, building codes for fire, water etc. hazards, but without zoning laws are there grounds to control noise, smell, traffic etc. ?
I can imagine there's at least a couple of landlords who would place a premium on shortening their supply chains in such a way.
Where I live, a lot of zoning laws are really ordinances, and the enforcement of different aspects of sanitation is split between the zoning ordinance and other ordinances. I wonder how the new anti-zoning law law handles that.
Sometimes there are things are obviously bad and harmful and it can be known ahead of time that it will harm people. These things should be stopped before they happen in a properly functioning society.
If someone invents a way to do it safely, they should have the burden of safely proving that first.
If someone wants to stockpile 100 tons of explosive material in my neighborhood, I don't want my estate to use the courts to find remedy after my section of the neighborhood gets leveled/cratered. I want the obviously harmful activity to be stopped before the hazard is created.
Thankfully it's not quite that level of anarchy,
it's just that new housing can be built without local governments saying "no". It isn't the case that heavy industry can now be placed next to an elementary school.
Also, given prevailing rents that would likely lose them money over renting it out, though you can certainly regulate your way into that being the best option if you "protect" renters enough.
