Kernrechtsfrage
Whether the BehiG required the building permit to order accessible pool entry aids for pre-existing pools in connection with the sauna extension.
Extrahierter Entscheid
No. Under Art. 7(1)(a) BehiG, only barriers linked to the approved renovation project must be avoided; existing pool basins unrelated to the project need not be retrofitted.
Extrahierte Begründung
The statute and its legislative history show an incremental adaptation duty tied to the permit-triggered project, not a general obligation to eliminate all existing barriers in the whole building.
