Many streets in New York have alternate side (ASP) regulations, which allow for street cleaning. Different streets have different time restrictions for cleaning (e.g. 8:30 am to 10 am), once or twice per week. Most alternate side parking (ASP) signs are clearly marked with signs featuring a "P" crossed by a broom.
The City suspends ASP regulations on 34 legal and religious holidays. ASP Regulations may be suspended from time to time because of snow, inclement weather or other emergencies. Some metered parking zones have ASP rules. When alternate side parking is suspended for a holiday or other reason, the parking meters remain in effect.
Double-parking of passenger vehicles is illegal at all times, including street cleaning days, regardless of location, purpose or duration. It is illegal to park within 15 feet of either side of a fire hydrant.
On major legal holidays, stopping, standing and parking are permitted except in areas where stopping, standing and parking rules are in effect seven days a week (e.g., “No Standing Anytime”). Parking meter regulations are also suspended on major legal holidays. The major legal holidays are New Year Day, Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas. On all other holidays, only street cleaning rules are suspended, and other regulations remain in effect.
