Was surfing the 311 site and came upon this one - complaint about people/businesses putting out private parking signs on public streets, in this case it was reported to be valet parking that put out their own signs on River Front Avenue and then charged to park in those spaces on a public street. Link to specific 311 report.
Now this isn't the only spot I've heard or seen this type of activity - there's a private/charter school (not sure which) in our community that puts out their own no parking signs every school day on a public street that has no parking restrictions. People generally obey those signs but I've often thought I should take thee 4 vehicles in our household and park them up there and see what they would do. Seeing as they're not a CoC sign, I would suspect there's nothing they could do.
Another area that has created concerns in the past is the area in front of the Rush restaurant downtown as they used to do the temporary valet parking area on a public street although that may have changed.
The deal with school's putting out their own special parking signage seems to be gaining traction as I've seen this around other schools in the city - as such, has anyone ever challenged people/businesses that put out these private parking signs on parking spaces on public streets? What's has been your experience if any?
