Rent reduction in the canton of Basel-Landschaft

Checked 23.09.2026 · Reference rate 1.25 %

In Basel-Landschaft a flat can be terminated for the end of any month except 31 December (§ 11 cantonal Introductory Act to the Code of Obligations). The notice dates in your lease take precedence over customary dates; the notice period for flats is at least three months (Art. 266c CO).

Customary termination dates

AreaDatesNote
Entire canton any month end Any 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).

Next deadline for a reduction request

For a lease in Liestal 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.
