Mexico City's mandatory short-term rental (STR) registration, opened on 22 May 2026 with a 30-day window, has logged roughly 27,000 registered properties against an estimated 30,000-plus active listings in the central boroughs.1 Mexican outlets covering the count describe 'clear signs of operational failure' at day 39.
Hosts and residents are fighting the system from both sides before enforcement begins. The 183-night cap it was built to police stays suspended by host amparos (constitutional injunctions), lodged in their hundreds, and Airbnb has filed its own. A single host can freeze enforcement against itself pending a ruling, so the cap is suspended in practice long before any court decides the merits.
Commercial operators registered as companies fall outside the three-property-per-host cap, concentrating the unregistered listings in exempt hands. The 274,000 nights booked across the 2026 FIFA World Cup window, roughly a month of the city's short-let demand, stay outside any enforced framework.
