Kernrechtsfrage
Whether the 42 m² basement hall, stairs and corridors could be included in the taxable rental value.
Extrahierter Entscheid
Yes. Including that area at 50% was not arbitrary under Geneva law.
Extrahierte Begründung
The space contained an interior staircase and circulation areas giving access to taxable rooms; it had market value and could be used, so its limited usability did not require exclusion.
