Photos surfaced this weekend of three different signs that appear to have been left on the front steps of the South Shore Chicago house that Kanye grew up in ... and which he bought in recent years and is reportedly in the process of renovating.

It also served as the centerpiece of his latest listening event there in town -- with Ye creating a replica version of the crib to help tell the story of his "Donda" album. Now, it's tainted.

Somebody left signage touching on Drake's lyrical shots that he fired last weekend ... in which he called Kanye "burnt out," among other things. One sign echoes those words exactly, while another warns that Drizzy's album, "Certified Lover Boy," is coming soon.

And, the middle sign randomly takes a swipe at Justin Laboy -- a social media influencer who's been relaying a lot of Kanye "Donda" news lately ... seemingly on his behalf.

Luckily, no real damage to the home was done ... but it still feels like crossing the line into a space that's obviously sacred to Ye. Unfortunately for him, the address is widely public ... and doesn't seem to have any barricades or security around to keep nosy prowlers out.

The fact someone had the gall to go to Kanye's actual house to do this perhaps speaks to the stunt he pulled on Drake this week ... posting the dude's Toronto address publicly.
