The Certificate of Conformity: A Key Document for Condominium Ownership

Welcome to the blog of Hochheiden Property Management, your trusted partner for comprehensive property management in Berlin. Today, we are addressing a topic of great importance to many apartment owners and prospective buyers: the Certificate of Conformity. This crucial document plays a decisive role in the process of forming condominium ownership and deserves special attention.

What is a Certificate of Conformity?

The Certificate of Conformity is an official document confirming that a residential unit within a building constitutes a self-contained unit. This means that the apartment is separated from the stairwell or other units by lockable doors and has its own sanitary facilities that are not shared with other units. The certificate is issued by the competent building authority and is a prerequisite for dividing the property into condominium ownership according to the Condominium Act (WEG).

The Importance of the Certificate of Conformity

  • Basis for the declaration of division: Without a Certificate of Conformity, no declaration of division can be created, and therefore no condominium ownership can be established. It is essential for the creation of condominiums.

  • Important for sale and financing: The presentation of a Certificate of Conformity is often required for the sale of a condominium and for applying for real estate loans.

  • Legal certainty: The certificate serves as proof that the structural conditions for the creation of special ownership are fulfilled, thus providing legal certainty for owners and buyers.

How to Obtain a Certificate of Conformity?

The Certificate of Conformity is obtained by applying to the competent building authority or the lower building supervisory authority. The application must be accompanied by building drawings that clearly demonstrate the self-contained nature of the residential units and the division of the building into special ownership and common property. After reviewing the documents and possibly conducting an inspection of the property, the certificate is issued.

Tips for Owners and Prospective Buyers

  • Early clarification: Ensure that a Certificate of Conformity is available for the property in question, especially if you plan to purchase a condominium.

  • Review of documents: Carefully review the Certificate of Conformity to ensure that all information is correct and consistent with the actual structural situation.

  • Consideration for renovation measures: Note that structural changes affecting the self-contained nature of a residential unit may require a new application for the certificate.


The Certificate of Conformity is an indispensable document in the field of condominium ownership, enabling a number of important legal and financial processes. Its significance should not be underestimated, and both owners and prospective buyers should familiarize themselves with the requirements and procedures for obtaining this document.
