"Parking access may be limited and/or inaccessible."

Contrary to claims made by the author of the no parking sign I found on my car the other day, access cannot be inaccessible. There is no such thing as second order access.

The author also claims that access can be limited and inaccessible at the same time.

Either something is or it isn't. If it is limited then it is. A thing can't be limited and nonexistent at the same time.

I suppose you could define 'limited' such that something that doesn't exist can be limited. But then it will always be both. It can't be one or the other.

So it's 'and' or 'or.' Not both. Not and/or.

This character lives in a strange world.
