Here in ARCC land (arcc-inc.org) we require "re coordination" whenever the coordinated repeater's "footprint" changes. A change in: Location? Definitely! EIRP? Yep! HAAT? Sure thing.
License change? Trustee change? Call change? Notification (preferably in advance) from a responsible source (trustee, licensee, "owner") will suffice most of the time. The primary responsibility of a coordination council is to maintain adequate co-channel isolation; predicting and avoiding interference as much as possible.
