With the support of partners of the EU-funded Save the Homes project, ICLEI has co-created an overview of key steps local governments should consider when exploring the establishment and operation of One-Stop-Shops (OSS). In broad strokes, OSS setup requires political support at various levels of governance, a robust understanding of the local building stock and the engagement of a broad ecosystem of stakeholders. Furthermore, an effective business model (usually involving stable and long-term financial support) must be established, OSS should be embedded in local strategies and plans, and OSS must be adapted to local legal frameworks. Lastly, OSS establishment needs to be guided by a well-defined customer journey, a concrete catalogue of services to be provided and an overarching communications strategy.
