What are the parcel ban and access heights?
The heights are:
- 800 m above the ground for Residents explicitly banned in the About Land window's Ban tab.
- 50 m above the ground for others not allowed on land, including restrictions in the About Land window's Access tab and the Ban tab's Deny by Payment Status options.
Falling from above onto a parcel you're not allowed into will cause you to continually bounce at the height limit.
Also, moving your camera close to a parcel you're not allowed into will make red NO ENTRY lines show up:
