Mexico City's Tourism Law cap of three short-let properties per individual host began implementation on 21 May 2026, with a registration deadline of 20 June, nine days after the World Cup opens on 11 June.1 The cap targets individual hosts, but the displacement engine is the professional letting firm: roughly 1,400 hosts holding four or more properties control about half the capital's short-let supply, led by named operators Virtual Homes (699 units) and Kukun (568).2
A per-individual cap is legally inapplicable to operators registered as companies, so the rule misses precisely the actors driving the consolidation. The legal unit of regulation, the person, no longer matches the economic unit of harm, the firm. In the central Cuauhtemoc borough, 11 to 20% of all housing now sits on Airbnb; Colonia Juarez has lost about 4,000 residents since 2020. Beyond the capital, Monterrey's short-let count has doubled to 7,274 and Guadalajara's risen by half to 9,760, supply built for the tournament.
The 20 June deadline escalates the situation documented on 20 May, when CDMX's unbuilt digital registry left 274,000 tournament nights unregulated, and continues the de-facto cap suspension that began under World Cup accommodation pressure. Airbnb's injunctions have paralysed both the registry and enforcement. Origin states are filtering who leaves; receiving cities find their tools miss who actually arrives.
