There are three parking lots/ramps adjacent to the theatre. They do cost money but you can also often park on the street for free if you're willing to walk a block or two.
There are a bunch of lots very nearby that you will pass on the way in the block surrounding. You need to get there a bit early, as the roads will be packed.
There are a couple parking lots right next to the entrance. Open air and covered
There is a 2 level pay lot south of the theater, entrance on 3rd Ave South.
