It appears that I can "grandfather" almost everything if I get approval from the building official (assuming it was compliant at the time of construction).
Primarily wind and seismic requirements. It's also a high-rise, so special egress requirements might apply.
Unfortunately I don't have the original drawings.
I'm new around here, so let me know if this is the wrong place for this:
I working on a renovation project for a building constructed in 1985. I need the structural and egress requirements under which the building was built so I can determine what elements need to be replaced/upgraded or left...
