Kernrechtsfrage
Whether the building application lacked the landowner's consent under Zurich planning law.
Extrahierter Entscheid
Section 310(3) PBG/ZH is a mere order rule; the authority may grant a permit even without landowner consent if no obvious third-party property rights are infringed.
Extrahierte Begründung
The court found no arbitrariness in the cantonal court's view that the provision protects the authority and does not require a detailed civil-law review of the building lease or property relations.
