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 .
