So you're sayin it isn't "typical" (for lack of a more precise word) for POTUS to have a sign in sheet at his residence during his presidency? Previous president's haven't done this?
Since I haven't heard the accusation, I'm assuming this is more of a suggestion than a requirement? >

It's neither.  The House GOP "investigators" demanded logs of Biden's visitors so they can come up with some bullshit story that one of these visitors could have snuck into his garage and accessed the classified documents that nobody knew were there.  
I'm sure they know Biden doesn't keep visitor logs at his house, but now they can accuse him of being secretive and hiding some kind of garage espionage scheme.
