As the January deadline approaches, which requires accommodations to have a National Identification Code to avoid penalties of 800 to 8,000 euros, attention is growing on compliance with the new regulations for short rentals. A few months after the law came into force, the ISSCON Foundation and the Federconsumatori National Observatory, with the contribution of the SUNIA union, conducted a survey to analyze the situation of tourist rentals in Italy. The results are worrying: out of nearly 1,000 properties monitored in 10 Italian cities, only 52% of the short-let facilities have applied for and obtained the mandatory National Identification Code (CIN). The situation varies significantly at the territorial level, with Naples leading the list of irregularities: only 32% of properties in the Neapolitan city are in compliance. This is followed by Florence (37%), Bologna (48%) and Turin (51%), while Rome (54%) and Venice (57%) are not far behind. The cities with the most positive data are Lecce, Catania and Milan, with the latter registering the best data: 67% of facilities have obtained the CIN.
