'My whole rental history, gone overnight': Zurich tenants speak out as duplicate-image glitch strips housing listings

Hundreds of people searching for flats in one of Europe's tightest rental markets say a recurring duplicate-image replacement error on major Swiss property portals has cost them viewings, deposits and, in at least a handful of documented cases, the tenancies themselves. The fault — which swaps original apartment photographs with recycled stock images or photos pulled from entirely different listings — has surfaced repeatedly since late May 2026 on platforms used daily by renters across Zurich.

The timing could hardly be worse. Zurich's vacancy rate for rental apartments sat at roughly 0.07 percent in the most recent figures published by the city's statistical office, Statistik Stadt Zürich, making it among the scarcest rental markets in the German-speaking world. When a listing loses its authentic images, many landlords withdraw it rather than field calls from confused applicants. For the person who had already booked a viewing, the damage is immediate.

Residents from Wiedikon to Oerlikon describe the same pattern

The accounts cluster in particular neighbourhoods. In Wiedikon, a woman who has been searching for a two-room flat since March says she spotted a Wohnungsnot-forum thread on the community board at Helvetiaplatz after her own chosen listing suddenly showed photographs of a completely different apartment — parquet flooring replaced by concrete, a balcony that did not exist. She refreshed the page three times before calling the agency, only to be told the listing had been temporarily suspended pending a photo audit. The viewing she had arranged for the following Saturday never happened.

In Oerlikon, close to the new Andreasturm development on Hagenholzstrasse, a group of four people looking to share a five-room flat say they lost their application window after the portal replaced their chosen listing's interior shots with images from a property in Altstetten. By the time the correct photos were restored, the landlord had already accepted another applicant. One member of the group said he had screenshotted every listing he bookmarked after that, a precaution he described as something no one should have to take.

The problem is not unique to one portal. Users report identical behaviour on both Homegate and Comparis, two of the three dominant Swiss housing search sites. Neither company has issued a public statement about the fault as of 4 July 2026. ImmoScout24 Switzerland, the third major platform, has not been mentioned in community reports reviewed by The Daily Zurich.

What community forums and tenant groups are saying

The Mieterinnen- und Mieterverband Zürich, the city's main tenants' association, which has its offices near Militärstrasse in Kreis 4, confirmed it has received a rising number of informal inquiries about digital listing errors in June and early July, though it has not yet opened a formal dossier on the duplicate-image issue specifically. The association has previously documented cases where misleading listing photographs contributed to disputes over advertised versus actual flat conditions.

At the Quartiertreffs — neighbourhood community centres — in Aussersihl and Langstrasse, the topic has come up at recent open-evening sessions, according to notices posted on their public bulletin boards. People are being encouraged to document discrepancies with timestamped screenshots and to report them directly to the relevant portal's user-feedback channel, as well as to the Mieterverband.

Switzerland's price watchdog, the Preisüberwacher, oversees fair commercial practices but has no direct jurisdiction over portal image errors unless a financial harm to a named party can be demonstrated. Under Swiss tenancy law, article 269d of the Code of Obligations governs what landlords must disclose, but there is no equivalent provision specifically addressing digital listing integrity on third-party platforms.

For anyone currently searching, tenant advocates advise requesting a direct PDF or email copy of all listing photos from the agency or landlord at the point of initial contact — before any viewing is confirmed. Saving the URL together with a browser-cached screenshot costs nothing and creates a timestamped record. The Mieterinnen- und Mieterverband Zürich accepts complaints via its Militärstrasse office on Tuesdays and Thursdays between 14:00 and 18:00, and online year-round at its publicly listed contact form.
