I'm not familiar with Texas' laws/codes on the matter like I am with California's, so this may be different there. But in CA, disabled accessible parking stalls are explicitly treated differently from disabled accessible EV Charging Stations (EVCS). And the section of the CA Building Code which deals with accessibility requirements when building an EVCS has language directly addressing your point by saying that for a disabled accessible EVCS, it needs to be on AN accessible route to the building entrance or AN accessible route to the pedestrian entrance to the charging area. I.e. it's explicitly not called out as being on the shortest such route like it is for accessible parking. See CA Building Code 11b-812.5. Since CA developed their rules for this matter first, I think most other states that have followed have just adopted theirs with minor modifications.These disabled spaces are not legal. The property owner thinks they are getting away with something, and maybe Tesla is mis-informing them, as it is a fairly common practice. The spaces must be the closest parking spaces to an accessible entrance. These are not. .
To someone else's point about the surface markings not being the same as for disabled parking, that is also by design. See CBC 11b-812.9
