Key legal question
Whether senior apartments are zoned-compatible in a public buildings and facilities zone
Extracted holding
No. Senior apartments are private housing and do not qualify as public or public-purpose buildings in the ÖBA zone.
Extracted reasoning
The zone is reserved for public works or works serving public purposes. Private housing, including state-supported senior housing, is not a public task under Solothurn law; there is no statutory public housing obligation or 'public living' for seniors.
