There should be more strict zoning laws. You can't have industrial processes happening anywhere near homes like these. I thought California was strict on zoning?
If there is an issue, it’s that these apartments were built (in ~2018). There are a number of other industrial sites nearby and the building was built in industrial zoning, after agreeing to numerous requirements to clean up the land to make it safe.
