Parking in Riverside

Hello, I recently moved to Riverside (near Fort Ave) and have been trying to figure out the best places to park. My roommates and I share one parking pad, so sometimes I have to find street parking depending on our schedules.

Last night, I parked on the corner of E Fort Ave and Riverside Ave and unfortunately received a parking ticket for stopping in a “no stopping” zone. I understand why I was ticketed, but I’m confused because I saw other cars parked in the same area, and they didn’t seem to get tickets.

Can anyone provide guidance on where I can legally park overnight in this area, especially on streets that don’t have posted signs? I’d really appreciate any tips to help me avoid future tickets.
