Brown spray painted the monster-like creatures on the outside fencing in front of his house.
Responding to complaints about the art, L.A. city code officials cited Brown for un-permitted and excessive signage and ordered him to remove the art within 30 days. He also faces fines that start at $376 but could rise significantly if he fails to comply.
But Brown says the hullabaloo is much ado about nothing. He has taken to Twitter to defend the work, saying, "There are scarier creatures on Harry Potter. Get a [$%#@] life!"
Brown's attorney, Mark Geragos, said the musician is not backing down. He says it's the neighbors who are harassing Brown.
Geragos said the city can expect a legal fight over Brown's personal artwork, which unwittingly thrust him into one of L.A.'s longest-running civic debates. Although the city has a reputation for being the street mural capital of the world, much of that artwork has been done illicitly.
City ordinances make it illegal to create murals on the vast majority of private properties.
