World Trade Center was not required to meet City of New York building codes because the Port Authority of NY & NJ is a semi-autonomous agency that operates under its own regulations.

These buildings met and exceeded all building codes, and they underwent continuous life safety upgrades over their 35 year existence.

The one thing the PA does well is spend a lot of money on safety.

You are right. My point was that all PA facilities are subject to their own internal inspections, standards, etc. and do not meet municipal codes (their own codes are probably more stringent in most cases anyway).
