Tommy,
I called the city to verify what I told you in person. The city will remove the graffiti one time as a courtesy but after that it is your responsibility to remove it. If they come out to paint this over you will be billed as its on your building. Hoping this changes soon. In the mean time PLEASE keep your walls clean so we can let the taggers know not to come to our block.
Thanks
