The school put up signs Wednesday morning saying, "No rideshare on this block. No pick up or drop off on Page Street between Masonic and Ashbury."
Our partner Hoodline was first to report on the new rule.
Urban issued a statement saying, "These services tend to stop right in the middle of the block, often on the very busy crosswalk that connects our two campuses, creating major safety issues."
San Francisco police say traffic and parking rules need to be evenly applied to all no matter who is driving.
The urban school told ABC7 that rideshare cars are welcome to use an established drop-off zone in front of the school just like private vehicles as long as they follow the rules and don't stop in random places.
