Your agreement with the girl you rent from is likely covered by the PA landlord tenant statute so she would be limited to what she could do to you.

Which doesn't mean she CAN'T lock you out and take your stuff. It only means that you would have legal remedies against her if she does. Which doesn't really help you much after you've been kicked out.
The statute requires her to give you 15 days notice of termination of your tenancy. See Section 250.501 (b).
That covers her relationship with you.
Unfortunately, the statute also says:
Section 250.105. Sublessees
Any person who is a sublessee shall be subject to the provisions of the lease between the lessor and the lessee.
That means that, if she is in non-compliance with her Section 8 lease requirements, you are also in non-compliance and she and you can be evicted together.
And, since she is in non-compliance, it appears that her landlord need give her (and you) the same 15 days notice of termination of tenancy.
In either case, once the 15 days are up, she can file for eviction against you or her landlord can file for eviction against both of you.
