Physically installing such a device “in a strata” should be no more difficult than in a private residence. There would be industry standards or best practices, depending the structure supporting the rails.
A lot would depend on the layout of the building and stairwells. In my block, a chair to the 2nd floor (which has Foyer, G, 1, 2) would require 3 separate installations as the stairs are not continuous.
Unless a building has been designed to accommodate lifts, it would be virtually impossible, or horrendously impossible, to retrofit them.
Another consideration if this is allowed, what happens if another owner decides they should also be entitled to have a similar personal facility?
