311 cannot give you information on how City parking rules might apply to specific situations. You should follow the rules posted about time limits and whether it is legal or illegal to park in a specific area. Because New York City Traffic Rules only require one sign for each block, you should check the whole block and read all signs carefully before you park.
You can find parking sign information and signs at specific locations using the traffic sign database or the DOTMap. On the map, you will have to zoom in to the street level of the location you want to view, and then select "Parking Signs" from the GIS Layers menu on the right. If there is construction or a recent update to parking rules, the database information may not be current. Always follow the posted signs.
