T-Pain Issued Notice to Clean Up Front Yard

T-Pain is letting the grass grow under his feet ... and it could cost him big time.

Officials in Leon County, Tallahassee issued the singer 2 notices last week to clean up his front yard by early December, or face daily fines that could stack up to $20k.

The county's Code Enforcement Board heard testimony last month which painted T-Pain as a hoarder and a slob when it comes to basic landscaping. He was a no-show for the public hearing.

According to court docs, his front yard grass and shrubbery are already longer than 18 inches -- and he has a ton of "junk" that's been sitting in the yard for more than 2 weeks.

Greener? Who knows, but it's definitely longer at T-Pain's crib.
