Limestone Facade

The front facade of our landmark limestone has moved forward leaving about an inch gap above a 3rd floor window. The engineers said it’s all structurally sound and that the facade can be re-connected to the building with angle brackets and a stainless steel rod and the gap be filled with epoxy mortar. My question is since this is a repair, does this need 1. Landmarks permission or 2. Work permit or both? Secondly can anyone recommend a stonemason to do this repair.
