How ASP works
Many NYC streets have alternate side regulations that reserve one side of the street for cleaning on posted days and times. When the sign is active, you cannot remain parked on that side of the street during the posted window. Always read every sign that applies to your curb, because nearby blocks can have different schedules.
Suspensions and holidays
NYC suspends ASP on specific legal and religious holidays and may also suspend it for weather or emergencies. Planned suspensions are posted by NYC DOT, while emergency changes are usually checked through NYC 311 or Notify NYC. Other parking rules may still apply when ASP is suspended.
Grace period
NYC 311 says drivers get a five-minute grace period past the time on an ASP sign. That is helpful, but it should not be treated as a strategy. If the sign says the window ends at 11:30, build your plan around being legal before then.
What aSpot should help with
aSpot should help drivers remember where they parked, compare nearby blocks, avoid wasting time in high-competition areas, and check whether the next restriction window makes a space risky.
Fast checks before you walk away
Do not move back too early
The city says ASP applies for the full posted time. A sweeper passing does not make the curb legal again before the window ends.
Check the exact side
The rule applies to the side being cleaned. Opposite-side signs may have different windows.
Suspended ASP is not free parking everywhere
Hydrants, meters, no-standing, bus stops, crosswalks, and temporary signs can still apply.
