The article presents the data related to the study “When the regime goes local: Local regulatory arrangements and land use sustainability” [1]. The data collection process comprises legal and document analysis as well as 35 qualitative interviews. Data analysis includes: 1) reconstructing the Swiss institutional soil regime, 2) tracing of land use planning and land use changes over the past decades in the areas selected for analysis, 3) identifying contextual factors influencing the local regulatory arrangements, 4) presenting the constraints of superior law applying to each case, 5) analysing actors’ games, the strategies they pursue, and the resources and instruments they mobilize, 6) describing and qualifying the local regulatory arrangement between actors. Data can be reused for future analyses of land use policy processes and their comparison in Switzerland and abroad.
