Ayuntamiento CDMX, Mexico City's municipal government, opened the short-let registry on 22 May at estanciaeventual.cdmx.gob.mx, with a roughly 30-day window that closes around 21 June1. The registry had sat unbuilt three weeks before kickoff; now the three-property-per-host limit and the 183-night annual cap have a working enforcement mechanism behind them. For a host renting flats in Condesa or Roma, the abstract cap has become an administrative deadline with a date.
The roughly 21 June deadline lands inside the World Cup window, the same weeks the cap was suspended in practice to accommodate. Tournament logistics and match scheduling sit with the World Cup desk; the housing and displacement consequence is the one that matters here. A host who misses the roughly 21 June deadline can be deregistered precisely when demand peaks, losing the single most lucrative month of the year while a registered competitor trades on. With about 274,000 short-let nights projected across the tournament, the revenue at risk per delisted host is concentrated, not spread.
The enforcement claim deserves a check. Mexico City has published no count of hosts registered before the deadline, so the registry's existence is established while its take-up is not. The mechanism is live; whether the city has the will or capacity to delist non-compliant hosts mid-tournament, against an Airbnb that filed an injunction earlier in the cycle, is untested. Ayuntamiento CDMX opening the registry is the reportable development; any compliance count would be the next story, and the city has published none.
