There are several possibilities for parking for meetings at the Michigan Union. Those who have UM parking passes can use the lot on Thompson. There is also one nearby lot that has some visitor spots and here is the link for that: https://ltp.umich.edu/lot/?xyz=c8. In addition there is a City lot on Maynard and Thompson, and there is on the street parking. For the on the street marking you can download an app called “epark Ann Arbor” that can be used with either Apple or Android phones.
