The shared areas fall under the same legal qualification as any one of their back yards or front porches, it's co owned PRIVATE PROPERTY.......ALL THE RULES APPLY thats why it's posted AT THE GATE.
If you were not specifically invited by a resident or have legitimate business there IN ANY PART OF THE PLACE you are trespassing.
Fine. I don’t contest that.
How does a resident know for sure that someone hasn’t been specifically invited?
Like, say my guests miss the house and end up in front of yours, how do you know if they’re trespassing?
