Travis get out side and take pics now of the signs that are in place and also across the fronts of the garages ( if there are no signs now ) dated would be great , newspaper headline in the background of one pic even better. I say this only because it could be handy incase new signage is put up or signs are changed I saw this because sounds like your apt complex did not follow the number two item # The vehicle has been issued a notice of parking violation, SO if you decide based on that alone to take the LL to court its hard to say for sure but if you argue in small claims court that your state law saying (2) The vehicle has been issued a notice of parking violation, and 96 hours have elapsed since the issuance of that notice.
If by chance you let small claims settle this and you win EXPECT that your LL will likely refuse to renew your lease , nit pick your unit when it comes time for you to move , to never ever allow any lease infraction of yours pass them by again.
