Building Wiring is regulated in many USA and Canadian locations through adoption of the NEC and CEC, with respect to Elecrical Safety. However, the Telecom aspects are not regulated beyond the establishment of a point of demarcation between the setrvice provider and the building owner.
ICT wiring often goes to the lowest bidder, which does not necessarily mean the best service or the best coordination between different cabling systems. There is a series of standards that was developed by TIA TR-41, that will provide good and safe building cabling. The standards are available from Global Engineering. Ciao, Vic Boersma
