Canton SG
In the canton of St. Gallen, every month-end except 31 December is customary. Termination dates stated in the lease take precedence over customary dates. The notice period for flats is at least three months (Art. 266c CO).
| Area | Dates | Note |
|---|---|---|
| Entire canton | 31.01. · 28.02. · 31.03. · 30.04. · 31.05. · 30.06. · 31.07. · 31.08. · 30.09. · 31.10. · 30.11. | Every month-end except 31 December. |
The termination dates in your lease always take precedence. For flats the notice period is at least three months (Art. 266c OR).
For a lease in St. Gallen without its own termination dates, our calculator currently works with 31.03. · 30.06. · 30.09.. The next reachable date: send the request by 26.12.2026, and the lower rent applies from 01.04.2027.
Where termination is possible at more dates, we deliberately use a conservative subset so that no request is sent too late.

The canton has seven regional conciliation offices: St. Gallen, Rorschach, Rheintal (Altstätten), Werdenberg-Sarganserland (Buchs), See-Gaster (Jona), Toggenburg (Wattwil) and Wil.
