Kernrechtsfrage
Whether the FAT minimum distance of 20 meters applies to a small horse stable that would also be permissible in a residential zone.
Extrahierter Entscheid
No. For a small-scale animal husbandry operation that would also be allowed in a residential zone, the FAT guideline minimum distance does not have to be observed.
Extrahierte Begründung
The FAT formulas yield useful results only from a certain odor load onward; for smaller animal holdings the guideline merely recommends the 20-meter distance, while the authorities may allow a smaller distance. Since two to four horses are allowed in the residential zone and only much smaller cantonal boundary distances apply there, equal treatment requires the same approach for a part-time farmer.
