The dissertation provides a detailed account of the legal bases, the history of the guarantee of acquired rights outside of building zones, the conditions for the application and the construction possibilities under article 24c SPA. The author places particular focus on residential buildings, the 2012 revision of the SPA as well as the provisions identity requirement. The dissertation calls for a more pragmatic approach to and improved use of existing building volumes. Within the existing scope of the law, the regulatory straitjacket should be loosened. Moreover, the balancing of interests should become the centerpiece which would enable sensible zoning practices. In this context, the now crucial identity requirement is to be reconsidered, and regional differences to be accorded more im-portance. At the same time, the author rejects a further loosening or expansion of the scope of application of article 24c SPA.deBaugenehmigungEDIS-5180Bauen ausserhalb Bauzonedoctoral thesis
