A real estate "for sale" sign ceases to become a for sale sign when a sold attachment is applied. Therefore they are illegal in the City of New York. This broker thought that he couldn't say sold enough on this property on 57th Ave. and 74th St. The problem is the homeowner is fined for the violation not the broker. And the fines are steep. Report these violations to 311. Mention to the operator Section 22-322 of the zoning resolution for the Department of Buildings that prohibits "sold" signs on for sale signs.
Also report illegal advertising on public property. You'll often see illegal real estate open house "A" frame signs blocking sidewalks and corners. Some real estate firms hang ads on poles and trees. Stop real estate companies from illegally using our streets and sidewalks to advertise their listings. Report these violations to 311.
