They didn't get the "Lead Safe Renovator" certificate and didn't know they were disturbing lead.

They seem to be concentrated in the kitchen, and swarm out of one cabinet in particular when you disturb it. 

But, it could also be no big deal if they are running a consulting business (like graphic design) where they sit in a chair inside and do not disturb anyone.In California, the state does not allow LLC's to use P.O.

If that’s an option, it’s appealing since you don‘t have to disturb the buyers until you have a serious buyer.

Personally, I feel safer shopping for my groceries in Playa del Carmen than anywhere in the US, where I could get shot by somebody mentally disturbed.
