Buy building land in the canton of Graubünden: undeveloped plots

In the canton of Graubünden, the official geodata analysed show 1'821 undeveloped plots in building zones across 52 municipalities (data retrieved 11.11.2026).

Of these, 1'070 plots carry the mark «Aerial image checked: nothing noticeable». On the evaluated aerial image (swisstopo, flight year 2025), 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 03.11.2026). 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.

Graubünden is a canton of valleys and passes, and trilingual: German, Romansh and Italian. From the Rhine valley around Chur, the capital, to the Prättigau, the Surselva and the Engadine, and on to southern valleys such as the Mesolcina, Bregaglia or Val Poschiavo, building zones mostly sit on valley floors and around villages. A building land search in the canton of Graubünden is accurate to the plot but only partial: the canton has so far released zoning data freely for just some of its municipalities. Where data exists, you can find building land among undeveloped plots identified in the official data we analyse. The municipal building authority and the land registry office can tell you more.

The pages for individual municipalities are in German.

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.
