Affitti brevi e vulnerabilità abitativa a Napoli: analisi spaziale della pressione di Airbnb e implicazioni per la regolamentazione urbana

The proliferation of short-term rentals (STRs) in Naples, mainly via platforms like Airbnb, has reshaped the city’s housing dynamics. This study conducts a spatial analysis linking STR distribution to socio-economic indicators, producing two composite indices: one for housing vulnerability, another for tourist pressure. Results show a strong overlap in central districts, where professionalized STR activity coincides with high rental rates, overcrowding, and low property values. This convergence increases displacement risks and reduces long-term housing availability. STRs thus emerge as drivers of digitally mediated rent gaps and agents of urban restructuring. The findings highlight the urgent need for regulatory responses to mitigate these effects. Policy recommendations include density caps, restrictions on multi-listing hosts, and data-driven planning tools to safeguard housing availability of affordability and address tourism-driven housing precarity.
