Swiss panorama for a guide to the rental market and tenants' rights

Security deposit of up to three months' rent, a blocked account and 30 days to challenge the notice of termination: the federal rules for St. Gallen.

Context

In brief

  • Security deposit: maximum three months' rent
  • Blocked account in the tenant's name
  • Landlord's notice of termination on the official cantonal form
  • Challenge within 30 days to the conciliation authority

Key facts

  • Legal basis → CO, Articles 253 et seq.
  • Scope → federal law, the same in every canton
  • Security deposit → maximum three months' rent
  • Account → blocked and in the tenant's name
  • Notice of termination → official cantonal form
  • Challenge → within 30 days to the conciliation authority

The security deposit for accommodation in Switzerland may not exceed three months' rent. The amount must be placed in a blocked account in the tenant's name. These are the two practical points to bear in mind when reading the rental rules in 2026.

The basis is federal tenancy law, referred to in CO Articles 253 et seq., and it is the same in every canton. For the canton of St. Gallen, this means that the security-deposit cap and the name on the account do not depend on different cantonal rules: the limit remains expressed in months of rent.

The landlord's notice of termination

The second step concerns the landlord's notice of termination. The communication is valid only if the official cantonal form is used. In St. Gallen, the tenant must therefore check the formality required by the canton, in addition to the content of the communication.

The rule also indicates the procedure for anyone who wishes to challenge it: the challenge must be submitted within 30 days to the conciliation authority. The deadline and the venue are part of practical protection and must not be replaced by a simple informal communication to the landlord.

The framework produces a clear nationwide comparison. The substantive rules on security deposits are federal and the same in every canton; the document to check for the notice of termination, however, is official and cantonal. St. Gallen thus enters the comparison not because of a derogation concerning the deposit, but because of the reference to its own forms.

For anyone considering accommodation, the correct reading starts with the actual rent and the formalities of the tenancy, without confusing the legal limit with an average price. costo della vita in Svizzera remains a broader calculation, but the security deposit has a precise rule: no more than three months. The fact that the rule is nationwide simplifies the comparison between a contract in the canton of St. Gallen and one in another canton. It does not, however, eliminate the need to check the forms, because that formality remains cantonal.

Operational details

The figure of three months’ rent should be interpreted as a maximum limit, not as a national average rent. Since the reference is the actual rent, the initial commitment varies according to the accommodation chosen; the rule does not establish a single amount in CHF. In the canton of St. Gallen, the comparison with the other cantons therefore starts from the same federal protection, while the termination form retains a cantonal reference.

What remains the same and what changes

The distinction between federal law and local procedure can be understood as follows:

Element
ElementCommon rulePractical interpretation
Security depositMaximum three months’ rentThe limit follows the rent
AccountBlocked and in the tenant’s nameThe account holder must be checked
TerminationOfficial cantonal formThe formality refers to the canton
Challenge30 days to the conciliation authorityThe deadline must be respected

In a hypothetical scenario, a request for a deposit exceeding three months would go beyond the limit set by federal law. If, on the other hand, the issue concerns a termination, the check to be carried out is different: the presence of the official cantonal form must be verified. One rule does not replace the other, because the security deposit and termination involve two separate checks.

The monthly budget also requires a clear separation. The cost of living does not coincide with the rent and does not coincide with the security deposit. LAMal/KVG is mandatory for residents, operates with per capita premiums and provides for premiums differentiated by canton or region; premium reductions are cantonal. AVS/AHV and LPP/BVG, on the other hand, are salary contributions, not deposit items.

To read data and comparisons without overlapping different aspects, UST/BFS belongs to the area of statistics, while tenancy law remains the federal law referred to by the CO. This distinction helps those living in the canton of St. Gallen avoid using data on the cost of living, an insurance premium or a salary contribution as if it determined the security deposit.

Key points

Before payment

1. Identify the rent specified in the lease: this is the basis against which to measure the limit. 2. Verify that the deposit does not exceed three months' rent. 3. Check that the amount is placed in a blocked account in the tenant's name. 4. Keep this check separate from any check concerning the landlord's termination notice.

The practical point is not to look for a single nationwide amount applicable to everyone, but to apply the limit to the rent indicated for the dwelling. In the canton of St. Gallen, as in the other cantons, federal law establishes the cap, and the account must remain in the tenant's name.

If a termination notice arrives

First check whether the landlord has used the official cantonal form. The validity of the termination notice depends on this formality. If you wish to challenge it, submit the challenge to the conciliation authority within 30 days. The time limit specified by the rule is concrete and requires you to arrange an immediate review of the communication received.

The procedure therefore changes depending on the problem: for the security deposit, check the months of rent and the blocked account; for the termination notice, check the form, deadline and conciliation authority. Keeping the two procedures separate prevents a request concerning the deposit from being treated as a challenge to the termination notice.
