Compton's Environmental Rules: The Rules That Matter

Every city handles environmental rules a little differently. In Compton, California, there are 5 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.
