I can only speak for Pennsylvania laws. I do know that the CARES act only protects renters from evictions that are living in apartments or homes that are backed by a federal mortgage program. As for shutting off utilities on other homes, that would work under certain conditions like, what time of year it is and if there are children in the home.
Also, landlords cannot do a self-eviction. This must be done by a Constable or Sheriff. Landlords who do these self-evictions can be held liable for any property damage caused during the eviction. Pennsylvania does not set tenants out on the street. There is a process that the Sheriff’s office performs to make sure that the tenants being evicted are treated responsibly.
