A sidewalk shed outside an apartment building credited with being the birthplace of hip-hop is becoming the focus of a legal battle after a hefty fine from the Department of Buildings.

The fine was issued because of the canvas covering the scaffolding in front of 1520 Sedgwick Ave. in Morris Heights. While the building calls the canvas a work of art, the Department of Buildings called it an advertisement.

The canvas has pictures of rappers, records and a website URL that promotes the building’s legacy. Because that website sells merchandise, the DOB issued a $2,500 fine to the building.

The canvas artist said that was never the intention.

"It's for the people. It was never about advertisements. We're about bringing awareness and the significance of the hip-hop birthplace," said Desire Nobility One.

The building owner says that more canvas' like this should be encouraged, not fined.

"The artwork has been on the building for more than a year. It's helped beautify the neighborhood. It's been well received by everyone who's seen it. With the exception perhaps of the city," said John Crotty.

The building owner told News 12 that they do not plan on paying the fine.
