Vienna Building Book: 54,500 properties to be documented by 2028, only 2,000 done

Vienna's digital Building Book initiative aims to inventory all existing buildings by 2028, but only about 2,000 of the estimated 54,500 have been documented so far. The program is a regulatory compliance effort with potential penalties for non-compliance, but the pace suggests significant administrative backlog. This is a local administrative matter with no immediate market or geopolitical implications.
