Source and date: abz.ch/wohnen/mieten, read on 4 November 2026. No guarantee; the ABZ page is authoritative.
The ABZ says it advertises available flats, parking spaces and studios online only. With the newsletter "freie Mietobjekte" you get an email as soon as a property is advertised. On its site the ABZ names 58 estates and 5160 flats.
How the application works
- An available property stays advertised on the website for at least 24 hours.
- Applications are only possible online: scroll to the end of the listing page, click "jetzt bewerben" and fill in the electronic questionnaire.
- A random generator picks 15 applications that are invited to the viewing. With the invitation you get a contact person.
- From all applications the ABZ chooses the suitable new tenant according to its letting regulations.
- According to its page, a call or an email to the ABZ achieves nothing.
- According to the ABZ, the best chances are with new buildings: look at the building projects and apply as soon as the flats are advertised.
Share capital
You become an ABZ member through an open-ended tenancy. The amount of the share capital depends on the flat size:
- 1.5 rooms: CHF 3500, 2.5 rooms: CHF 4500, 3.5 rooms: CHF 5500
- 4.5 rooms: CHF 6500, 5.5 rooms: CHF 7500, 6.5 rooms: CHF 8500
- The minimum share per member is CHF 1500. The share capital is divided among the contracting parties and must be paid in full by handover of the flat. After you move out you get it back if all obligations under the tenancy are met.
Fixed-term tenancies
When an estate is about to be renovated, the ABZ lets available flats there only for a fixed term, and likewise certain flats as temporary replacement flats. Anyone living there for a fixed term does not become a member and, according to the ABZ, has no right to a follow-up solution after the contract ends.
What follows for your search
This is our assessment, not a guarantee: because every listing is online for at least 24 hours and the applications are drawn by lot, it matters less to be seconds fast than not to miss a listing altogether. Wohnify checks cooperatives' pages about every 30 minutes and sends you an alert when something suitable appears. We cannot guarantee you a flat.
