Questão jurídica principal
Whether the sex-business use of the apartment is zone-compliant and thus retroactively approvable.
Decisão extraída
The use is not permitted in the residential zone; the municipal authority could refuse approval and the restoration order remains justified.
Fundamentação extraída
Under the applicable zoning rules, residential zones are primarily for housing and only non-disturbing uses. A sex-business operation creates ideational immissions and conflict potential incompatible with that use. The federal court found the cantonal court's interpretation neither arbitrary nor unequal.
