My read on (b)(2) is that the first part of the subsection states what conditions the exemption does not apply for. And the intent is that the exemption does not apply when the parking fee at the facility is charged by the monthly/week or year. Certain state owned lots (primarily the ones where employees park) charge by the month for parking - there is no daily or hourly fee, because the general public can't park there. The airport is an interesting test case though because the posted rates indicate a flat daily rate of $12/day after 24 hours in the lot.
My question is - can I go to UH games at the stadium and UH now and park for free? Last I checked the stadium is a state facility.....
Ah, that's another way to interpret it as well. Good point.
And as for the stadium, dunno. If you're going to Stan Sheriff Center or the baseball field in UH lower campus and parking in the lower parking lot, that is free though.
