BE AWARE !! The city of Los Angeles and those cities to whom they provide parking enforcement are VERY money hungry. The city posts a plethora of confusing, contradictory signs which also change the rules by different days and different hours.
In addition, one cannot appeal because one must send the fine to a collection company which is not even in the same county. The appeal process on the city website does not actually exist.
Even though I have lived in the LA county almost continuously since 1964, I have never seen such avarice. I avoid Los Angeles at all costs.
