I can't believe they charge for parking now it's been free for years ugh....
the best free parking is at the tri-rail station, the West Platform is on N30th street where it is a short walk to where the market is. There is a step down from the platform so it is not wheelchair accessable. There is an elevator (and stairs) in the pedestrian bridge over the tracks.
There is undesignated parking (area Destiny said outside of the gate) that I would not suggest. You run the risk of your car being damaged by the next door businesses or towed if someone is in a mood.
Only on the outside of gate. They just recently changed it to paying at pay station for $5.
