The Great Hall does not have dedicated parking - there is free, residential street parking to the west, pay, commercial street parking to the east, and a pay lot under PCC (one block away.)
There is also a Park-and-Ride just under I-5 at roughly 65th and 8th St, which works well if you have a person offering to shuttle people back and forth (or there are services which can do this, such as First Student Charter Bus.)
Uber, Lyft, and other rideshare programs are highly recommended for the venue (especially if alcohol is being served.)
For weekend events, we are able to secure 2.5 spaces next to the Northwest corner of the building utilizing city No Parking signs. We recommend using these spaces for load-in / load-out purposes and finding parking elsewhere when you are done actively loading so as to allow others in the event to use the space. Please note that while the city provides these free of charge to us, there are no means to enforce them. We suggest pulling the signs into the streets when the spaces are not being used so that the public does not park there.
