What Happened
On September 1, 2026, Zürich implemented a sweeping regulation against the conversion of residential apartments into commercial short-term rentals. The city's Building and Zoning Ordinance (Bau- und Zonenordnung, BZO) revision—confirmed by Switzerland's Federal Court after private legal challenges—prohibits short-term rentals (STRs) like Airbnb units and business apartments from counting toward the city's mandatory minimum residential housing quotas.
The rule targets properties rented commercially for periods under one year on a regular, ongoing basis. Property owners must now declare such uses; occasional rentals of one's own apartment during absences remain exempt. To enforce compliance, Zürich allocated five new full-time staff positions and launched a formal reporting system.
"Temporarily rented apartments, such as Airbnb accommodations or business apartments, can no longer be counted toward the prescribed minimum residential share if they are regularly rented commercially for periods under one year." — City of Zürich official statement

Key Takeaways for Hosts
-
Declare Early and Fully: Zürich's city office explicitly states it will process reports starting September 1, 2026. Do not wait for an audit notice. File your rental-term declaration immediately with the Amt für Baubewilligungen (afb-kurzzeitvermietungenbzo@zuerich.ch).
-
Distinguish Occasional from Commercial: If you rent your own apartment occasionally while traveling, you are exempt. Keep clear records (dates, booking intervals) to prove occasional status during any review.
-
Expect Permit Requirements for Usage Changes: Any shift from long-term to short-term (or vice versa) requires a building permit, regardless of physical alterations. Budget time and legal review into any operational pivot.
-
Understand Local Housing Policy: Zürich's rule reflects a broader housing shortage and affordability crisis. Regulations targeting STR conversion are spreading across Europe. Check LawfulStay for similar rules in other cities where you operate.
-
Monitor Federal and Cantonal Trends: Swiss federal courts have now upheld Zürich's stance twice. Expect similar regulations in other Swiss cities (Bern, Basel, Geneva). Proactive compliance now prevents forced exits later.
The Bigger Picture
Zürich's September 2026 enforcement marks a major tightening of STR regulation in continental Europe. Unlike looser frameworks in some US cities, Swiss municipalities are taking a planning-based approach: STRs are not banned outright, but their conversion effect—removing long-term housing stock—is restricted. This mirrors actions in Barcelona, Berlin, and Amsterdam.
The Federal Court's confirmation of Zürich's rules eliminates legal ambiguity for hosts who hoped private challenges would overturn the regulations. Other Swiss cantons are watching closely. Expect Geneva, Bern, and Lucerne to adopt similar measures within 24 months. The era of unregulated short-term rental growth in Swiss cities has ended.
