They are a strange anomaly. To me it is basically a hotel pretending to be a residential block. If the rooms can be classed as domestic premises then the common areas definitely come under UK legislation, but not under scottish legislation. Common sense says to me that the rooms are not domestic premises due to the way they are let out, it is more akin to a hotel and as such the RRO applies throughout. The evacuation policy will make a difference to the standard of alarm that should have been installed. Full evac in the event of a fire in a room should really necessitate a L2/L3 (minimum) system. Stay put should only need something like residential, i.e. Part 6 in apartments only. I believe that the argument remains to be sorted as to whether they are truly domestic or not, but someone else somewhere may have had a determination to give us a definitive answer to that, but an FRS would probably argue that it is technically a hotel, while the designer would argue it is residential.
