Barrier district - Sperrbezirk
In principle, prostitution is allowed in Germany. The authorities of a federal state can, however, prohibit the practice of prostitution in certain areas by means of an ordinance . The basis of authorization for this is the Introductory Act to the Criminal Code (EGStGB) . According to this, in order to protect youth or public decency , it may be forbidden to engage in prostitution:
in principle (i.e. both public and in buildings)
- in municipalities with up to 20,000 inhabitants in the entire municipality (Art. 297 (1) 2.),
- between 20,000 and 50,000 inhabitants in whole or in part (sentence (1) 1.-2.),
- with more than 50,000 inhabitants only for a certain part of the municipality (sentence (1) 1.);
on public roads etc.
- regardless of the size of the community in whole or in part (sentence (1) 3rd),
- in this case the ban can be limited to certain times of the day .
The term “pursue” includes prostitution itself and also making contact with customers. Infringements can be prosecuted as an administrative offense according to Paragraph 1 No. 1 of the Law on Administrative Offenses (OWiG) or - if the offense is persistent - as a criminal offense according to Criminal Code (StGB) .
Free , according to the aforementioned EGStGB not affected by the bans. However, many municipalities prohibit in local police regulations from addressing prostitutes in restricted areas. A typical formulation is:
"In the restricted area it is forbidden to contact prostitutes in order to arrange sexual acts for payment."
In Baden-Württemberg , according to the ordinance of the state government on the prohibition of prostitution of March 3, 1976 , it is fundamentally forbidden to pursue prostitution in communities with up to 35,000 inhabitants. This means that prostitution is only permitted in around 46 municipalities in Baden-Württemberg.  The adoption of individual Sperrbezirk regulations in municipalities over 35,000 inhabitants is on the four regional councils transfer (Freiburg, Stuttgart, Karlsruhe, Tübingen).
In Bavaria , with the ordinance on the prohibition of prostitution , it is fundamentally prohibited to pursue prostitution in communities with up to 30,000 inhabitants . This means that prostitution is only permitted in around 34 municipalities in Bavaria.  With the consent of the municipalities, municipalities can be wholly or partially exempted from the ban.
With the Thuringian Ordinance on the Prohibition of Prostitution of April 24, 1992  , prostitution in Thuringia is generally prohibited in municipalities with up to 30,000 inhabitants. This means that prostitution is only permitted in around ten municipalities in Thuringia.  With the consent of the municipalities, municipalities can be wholly or partially exempted from the ban. The authorization to issue restricted areas was transferred to the Thuringian State Administration Office.
Colloquially, the restricted area is sometimes incorrectly referred to as the “ restricted area ”.
