Madonna's Allowed to Police Her Own Driveway!

Madonna says she has exclusive rights to the curb outside her NYC residence ... claiming the concrete in question is actually her personal driveway that leads into her private parking garage.

The Department of Buildings tells us that the singer does indeed have the right to a clear driveway, but she doesn't have the right to paint the curb or put up no parking signs on public property.

As TMZ first reported, Madge's neighbor was pissed she had a "Tenant Parking Only" sign and a yellow-painted curb in front of her place. The neighbor looped in the Department of Transportation who demanded Madonna remove the fake sign in addition to the DOT re-painting the curb.

According to the Dept. of Buildings, Madonna has the right to tow people using her spot, but she can't deter them with unauthorized signs.

Madonna just Instagrammed, "Yes Bishes I am Madonna and that is my driveway and if people park in front of it I can't drive in my driveway! So sorry the city doesn't like the color yellow! We will paint a nice dull grey to keep our neighbors happy! Sorry. I'm saying 3 extra Hail Mary's this Easter for this transgression."
