What does "MIS" Stand for in NYC Dept of Buildings

[Meghan Danaher]

hi there! I'm looking to purchase a property in NYC.  There was a complaint filed on the property in 2010 but it was resolved per the NYC Department of Building website.  On the complaint, the inspector cites that the complaint was not valid and then cites an "MIS" case number.  Does anyone know what the MIS office is?  I'm trying to figure out a way to contact MIS to get more information on the compliant and how it was resolved.
