There is a farmer’s market at the Kaiser headquarters in Pasadena located on Walnut.

Kaiser Pasadena Farmer’s Market
393 E. Walnut Street

Apparently the location is near an overhang of some sort, I could not see it from the street, but perhaps next time I will park and look closer. It is open to the public from what I have been told.
