A searchable database on the New York City Department of Transportation’s website lists the parking regulations for both sides of every street in all five boroughs. The regulations are on signs that read, for example, "No Parking," "No Parking Anytime," "1 Hour Parking 8:30AM-7PM Except Sunday," and "Bus Stop." The website also provides a detailed description of the meaning of each sign.
To use the database, choose a borough from the drop-down menu, type in the street name (abbreviations are acceptable), click "Get Cross Streets," choose a cross-street from the drop-down menu, choose the other cross-street from the drop-down menu, click "Search," and scroll down the page.
Data is updated six days a week, Mondays through Saturdays. The information is taken from the New York City Department of Transportation’s sign database.
