What maximum number of storeys applies in the old commercial zone under the KBV transition rules?
Decisão extraída
The municipal zone rules had to determine the permitted storey number; in the City of Solothurn's commercial zone the applicable limit was at least two and, via the building-height rule, effectively four storeys.
Fundamentação extraída
Under § 16 KBV the municipality must still fix the maximum storey number in its zoning rules. The commercial zone of Solothurn was indirectly limited by the permitted building height of 14 m, corresponding to four storeys under § 18 KBV; at minimum, the cantonal fallback rule would have yielded two storeys.
