Kernrechtsfrage
Whether the sewer connection fee for a new building replacing a demolished old building must be calculated on the full building insurance value of the new building.
Extrahierter Entscheid
Yes. For a genuine new build newly connected to the sewer system, the fee is based on the full current insurance value, without deducting the demolished building.
Extrahierte Begründung
The regulations distinguish between new buildings and mere value increases from alterations to existing connected buildings. In a replacement new build, no remaining building substance is carried over; the demolished structure has been intentionally eliminated, so there is no basis for reducing the fee by its former value.
