Yes, you can.
While it is far more common to be stopped for DUI on pubic roads in Kansas, you can be charged for DUI on private property. This applies to parking lots with public access as well as friends’ or relatives’ properties.
In a parking lot, a police officer can investigate and arrest you for DUI if they have probable cause.
However, a police officer is not entitled to enter a friend’s private property and arrest you if your friend has given consent for you to be there and is aware of your conduct.
