Accessible units: what inspectors check differently

In accessible units, the accessibility features themselves are inspected as installed: grab bars solid and correctly placed, clear floor space open, controls and hardware reachable and operable. The common self-inflicted wound is a turn that removes or blocks a feature. What do your pre-walks check in accessible units that they skip elsewhere?

The painful version of this deficiency is self-inflicted: a grab bar removed for a tile job and never reinstalled, a closet conversion eating clear floor space, a lever handle swapped for a knob from the truck stock. The features are the inspection in these units, so the pre-walk has to treat them as the main event, not a footnote to the standard unit list. What does your pre-walk check in accessible units that it skips everywhere else — and have you ever caught a turn undoing an accessibility feature?
