Heritage Protection Permit

Any work on a listed building or monument (Baudenkmal) in Germany requires a heritage protection permit (denkmalschutzrechtliche Genehmigung). This includes exterior and interior alterations, renovations, extensions, demolitions, and changes of use that affect the historic substance. Even installing solar panels or replacing windows on a protected building typically requires approval.

You apply at the local monument protection authority (untere Denkmalschutzbehörde), usually part of the district or municipal administration. Required documents include site plans, building drawings, photographs, and a description of the planned measures. The authority consults with the state monument office (Landesamt für Denkmalpflege). Carrying out work without a permit can result in fines, criminal prosecution, and orders to reverse unauthorised changes. Each federal state has its own monument protection law.
