Structural and egress requirements for renovation

[Postmodernist]

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 in place. Some version of the Standard Building Code was used, likely early 80s, late 70s at the earliest.
Any ideas?

Thanks!

What specifically are you needing from the original code?
Do you have the original structural drawings?

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.

Do you have to upgrade? or can you 'grandfather'?

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).

Inquire and meet with the building inspection department. They are ultimately the department that will pass on what you are trying to do.

Now all I need is a copy of the 1979 SBC. Any ideas?
