Kernrechtsfrage
Whether the refusal of the occupancy permit for the apartment was lawful despite the staircase not meeting the 90 cm requirement.
Extrahierter Entscheid
Yes. The permit could be refused because the staircase did not comply with binding fire-safety requirements and the building conditions attached to the construction permits.
Extrahierte Begründung
Under the cantonal rules, occupancy requires compliance with permit conditions and applicable regulations. The fire-safety directive formed a sufficient legal basis, and the non-compliance also raised occupant-safety concerns.
