This is called a common property by-law and it has a condition that ongoing responsibility for maintenance must be ascribed to the lot owner otherwise it defaults to the OC. Thus the OC can make it a condition of the by-law that the lot owner (and all subsequent owners of that lot) accept responsibility for maintenance and repairs. If the lot owner refuses, then the OC is entitled to refuse to allow the installation. In some circumstances the OC could even ask the lot owner to pay for taking over common property. And who pays the electricity bill for the chair lift? A strata lawyer really should be consulted on this (at the lot owner’s expense).
