Third Floor Rehab Codes in Pittsburgh

[Brian L Dowler]

Pittsburgh PA has  alot of grand old houses in need of rehab - I have found many of these have third floors with room to add a bedroom or additional bath - in some cases there is room for a complete apartment or efficiency.

I have found that if adding a third floor apartment, you must have a fire escape.  however, my question today is in regard to adding a third floor bedroom to a single door unit - what codes are in place?  Do you need egress windows?  Escape ladders?  Fire escapes?

Can anyone point me to the right website address to review codes?
