FRAs in Existing & Purpose built blocks of flats

[Kevin99]

Hello

I am trying to find a reference for existing & purpose built blocks of flats built prior to current legislation/approved codes. 

Most existing buildings will not meet current legislation, how do I confirm or verify this fact. i.e that an existing escape exit may not meet current minimum sizes of 1100mm?

Could someone direct me to where I can discover this and how to best reference and apply it to FRAs.  

I hope that makes sense?

Regards

Kevin
