Renting an apartment in a cooperative is not the same as a rental contract on the free market. Cooperatives aim to create affordable and socially mixed housing. To prevent speculation and provide apartments to those who truly need them, special rental conditions apply.
1. Membership and Share Certificates (Anteilscheine)
The most important difference: When you move into a cooperative apartment, you usually do not pay a classic rental deposit, but instead buy share certificates (Anteilscheine). This makes you a co-owner (cooperative member) and gives you voting rights.
- Amount of capital: The sum depends on the size of the apartment and the respective cooperative. It can range from a few thousand to over ten thousand Swiss francs.
- Interest: Share certificates are often moderately interest-bearing.
- Repayment: When you move out, you get the invested money back in full (usually after a certain period).
2. Occupancy Rules (Minimum Occupancy)
Since cooperatives want to use the scarce land in Zurich efficiently, strict occupancy rules apply (avoidance of under-occupancy).
- The rule of thumb: Number of rooms minus 1 = minimum number of people. (Example: For a 4.5 room apartment, at least 3 people must live in the household).
- Relocation obligation: If the family size changes (e.g., children move out), many cooperatives require an internal move to a smaller apartment.
3. Income and Wealth Limits
Especially for city-subsidized projects in Zurich, it is checked whether the applicants really rely on affordable housing.
- Upper limit: Your taxable income must not exceed a certain maximum value. This is often calculated using the formula: Net rent x 4 to 6.
- Regular checks: In subsidized settlements, you must periodically (e.g., every 2 years) submit your tax return. If your income rises massively above the limit, a solidarity contribution (higher rent) may be due.
Conclusion
The rental conditions for housing cooperatives in Zurich require solidarity and flexibility. In return, you benefit from an extremely secure tenancy, lower costs, and often a strong neighborhood community. Before responding to a listing on Gnossi Wohnig, you should always briefly check the regulations of the respective cooperative to see if you meet the specific criteria.
