DIAZert-Zertifizierung nach DIN EN 15733 – was bedeutet das?

Wer in Leipzig eine Immobilie verkauft oder kauft, wünscht sich vor allem eins: Verlässlichkeit. Genau hier setzt die DIAZert-Zertifizierung an. Die Zertifizierung basiert auf der europäischen Dienstleistungsnorm DIN EN 15733 – einer Norm, die Anforderungen an die Arbeitsweise von Immobilienmaklerunternehmen definiert.

Die Zertifizierungsstelle DIAZert (ein Bereich der DIA Consulting AG) verfolgt dabei das Ziel, Qualität in der Immobilienbranche durch strenge Prüfverfahren und unabhängige Bewertungen sichtbar zu machen.

Was wird bei der Zertifizierung geprüft?

Die Norm stellt hohe Anforderungen – unter anderem an:

  • Fachliche Qualifikation (als Mindeststandard wird ein Niveau beschrieben, das etwa dem Immobilienfachwirt (IHK) entspricht)
  • Verhaltensregeln & professionelle Abläufe im Kundenkontakt
  • Informationspflichten, die Kundinnen und Kunden schützen und Transparenz schaffen
  • Dokumentenprüfung, Fachprüfung und – je nach Unternehmensgröße – Vor-Ort-Audit
  • Befristung & Rezertifizierung, damit der Standard nicht nur „einmalig“ gilt
