If you purchase a parking session that is shorter than the maximum time limit for the zone, you will be prompted to extend your time before your session expires. If you wish to extend your time, simply follow the prompts in the app to extend up to the maximum time limit for your zone.
You must extend prior to the expiration of your original parking session.
The City of New York enforces overtime parking regulations. If you choose to park in a space for longer than the posted limit, paid or not, you can be issued a summons by enforcement officers
Once your session expires, you will not be able to extend your parking session or use the ParkNYC app again in the same zone for 30 minutes. This is to discourage overstaying time limits.
