When you enter the rental complex here on foot, you are greeted by this cheery, upbeat notice:
There's a law in California that was passed by plebiscite, proposition 65, that requires businesses to warn people if they might be exposed to certain chemicals that might cause cancer or reproductive harm on their premises.
I find the phrasing of this one interesting, particularly the "not limited to" part. The chemical they have here that they actually have to tell you about is asbestos. I know because I have rented here twice, and both times they specifically discussed that at the signing of the lease. I guess you don't have to list every carcinogen on the notice though, and they have made a strategic choice on the ones to mention.
