Buy building land in the canton of Solothurn: undeveloped plots

In the canton of Solothurn, the official geodata analysed show 3'570 undeveloped plots in building zones across 102 municipalities (data retrieved 11.11.2026).

Of these, 1'973 plots carry the mark «Aerial image checked: nothing noticeable». On the evaluated aerial image (swisstopo, flight year 2024), no building and no installation was detected on the plot (except small structures under 12 m²), and no building of 12 m² or more is recorded in the official cadastral survey (status 04.11.2026). Trees and shrubs are possible; in this evaluation, vegetation does not lead to the classification «to be clarified on site». The check is automatic, on our own infrastructure. Every plot is checked on the aerial image and in the official cadastral survey. In two randomly drawn samples of 150 plots each, separate image evaluations supported the finding in 86 to 95 % of cases, depending on the counting method (status 04.11.2026; method: bauland-scout.ch/en/methode.html). The mark is an indicative value and does not replace a site visit or information from the building authority.

Solothurn has an intricate shape, running from the Jura with the Thal and the Schwarzbubenland to the Gäu and the Olten area, then on to the Wasseramt and the Bucheggberg in the Mittelland. The capital, Solothurn, lies on the Aare, and German is spoken. Settings therefore vary widely, from Jura villages to towns along the Aare. For a building land search in the canton of Solothurn, Bauland-Scout fetches zoning data through its own cantonal adapter from the canton's services. You can find building land among undeveloped plots identified in the official data we analyse, whether or not they are advertised. Building rules are explained by the municipal building authority, ownership by the land registry office.

The pages for individual municipalities are in German.

Official contacts: geoportal, cadastre, land registry

Bauland-Scout brings together official geodata and filters out the undeveloped building zones. It does not replace the cantonal geoportal (GIS) or the PLR cadastre: legally binding extracts, the zoning plan and certified cadastral extracts (cadastral surveyor or land registry office) are available from the official authorities.
