Hydrants. The rule is to give 15ft from either side of the hydrant, and though folks outside my apartment building are constantly parked in front of ours, I promise you, you will get ticketed.
Double parking. It's illegal at all times, including during street-cleaning days, despite a persistent myth to the contrary and whatever shenanigans your neighbors pull. As an adult committed to common human decency, I can't recommend it.
Legal holidays. On major legal holidays, standing, stopping, and parking sign rules are generally suspended except in cases where the signs say they are in effect seven days a week, i.e. "No Standing Anytime." (See below for a full distinction between legal and religious holidays.)
Towing. In addition to getting a ticket, your car can 100% get towed in New York if it is parked or operated anywhere illegally or has missing or expired inspection or registration stickers. Them's the brakes [not sic].
