Take a garage, convert it into a house without permission. It's really easy! Then park a car with an out-of-state plate on the lawn instead of the driveway.
This has been going on for more than a year at 57-40 Mazeau Street in Maspeth. There are people reportedly coming and going at all hours. DOB Commissioner Robert LiMandri has full knowledge of the situation and apparently doesn't care. And when you send a letter to Attorney General Andrew Cuomo, you get a response along the lines of "DOB states that this structure is not in need of a C of O because it was built before a certain year."
Force the house to be vacated and restored to its original condition.
