Whoever wants to operate a prostitution establishment in Schleswig-Holstein rarely needs just one permit. As a rule, they need two: the commercial license under the Prostitutes’ Protection Act (ProstSchG) and land use zoning that permits this specific use. Both procedures run through different authorities, according to different standards, and at different speeds. Anyone who only realizes this after signing the lease and paying the deposit has already made the most expensive mistake in the industry.
This text describes what the permit requirement for prostitution establishments in Schleswig-Holstein means in practice: who needs a permit, which authority decides, what goes into the operating concept, what obligations apply after issuance — and where building and planning law sets its own rules.
Two Procedures, Two Standards
The ProstSchG has applied nationwide since July 1, 2017. It introduced a permit requirement for the prostitution business, which sits alongside the general business registration under § 14 GewO — the registration does not replace the permit, it supplements it.
Building and planning law, however, was left unchanged by the law. The Federal Administrative Court explicitly confirmed this in its judgment of November 9, 2021 (4 C 5.20): The Prostitutes’ Protection Act changed nothing about the framework of building and planning law. Two separate approval tracks that do not replace each other — that is the starting point for any site planning.
Who Needs a Permit — and Who Doesn’t
Four Forms of the Prostitution Business
The law encompasses more than the classic brothel under „prostitution business.Supervision is regulated by Section 29. Officials of the competent authority may enter premises and business rooms during normal operating hours, conduct inspections and audits, review business records and documentation, and carry out identity checks at locations where prostitution is practiced. In practice, municipal authorities, police, customs, and sometimes financial administration appear jointly.
Anyone operating a prostitution business without the required permit commits an administrative offense that can be penalized under Section 33 Para. 2 No. 1 ProstSchG with a fine of up to €10,000. Additionally, the administrative authority may recover profits earned from the operation when determining the fine – the economic damage then regularly significantly exceeds the fine.
The Second Path: Building and Planning Law
The permit under the ProstSchG says nothing about whether the use is permissible under building law at that location. The framework for this is set out in the Building Use Ordinance, and the case law on it predates the ProstSchG:
- A brothel operation is classified as a „commercial enterprise of any kind“ that is generally permissible in commercial areas under Section 8 Para. 2 No. 1 BauNVO – and not as an entertainment facility that is only exceptionally permissible there.
- In a general residential area, a corresponding change of use is not permissible, not even exceptionally.
- In mixed-use areas, the situation has become more differentiated. The Federal Administrative Court clarified in 2021 (4 C 5.20) that milieu-related concerns – disturbances from intoxicated customers, organized crime, exploitative pimping – are not urban planning considerations; such dangers must be addressed through administrative law means, not through building planning law. Higher courts have since examined on a case-by-case basis the compatibility with the area, for example along the lines of intensity of disturbance and the distinction between residential prostitution and brothel-like operations.
For planning, this means: Before the lease agreement, the question of change of use belongs to the building supervision of the municipality or district – and in parallel, the question of whether the location is even outside a restricted area. Which municipality in Schleswig-Holstein prohibits what varies considerably; an overview of the system is provided in the article on where sex work is permitted and where it is not. There is no statewide master list of restricted areas – the definitive information comes from the local municipal authority.
Numbers, Orders of Magnitude, Open Questions
Official statistics only reflect administrative processes. Nationwide, the number of valid permits for a prostitution business fell to 2,250 by the end of 2024 from 2,310; at the same time, approximately 32,300 sex workers were validly registered under the ProstSchG, 5.3 percent more than in the previous year, and by the end of 2025, it was approximately 32,500. The statistics explicitly say nothing about unlicensed operations and unregistered persons.
A publicly available, daily-updated figure for permits issued in Schleswig-Holstein alone does not exist; the values for each state are published by the Federal Statistical Office in separate tables, and figures for individual districts and cities are provided by the respective municipal authorities upon request. If you need a reliable figure for your district, ask them – invented state-level figures help no one.
What’s in Motion in 2026
The evaluation of the ProstSchG by the Criminological Research Institute Lower Saxony was presented to the Bundestag on June 24, 2025. The findings for the permit procedure are mixed: from the perspective of the responsible officials, the regulations on permits and supervision have proven to be largely practical and adequate. However, operations without permits are difficult to detect – and from the perspective of applicants, the procedure is associated with high bureaucratic effort and sometimes takes a very long time. It is also criticized that obligations such as registration and ID requirements have a stigmatizing effect and tend to drive activity underground rather than create protection.
An independent expert commission is currently working on concrete proposals; initial results are expected by the end of November 2026. In parallel, the political debate over a sex purchase ban based on the Nordic model continues, promoted by parts of the Union and rejected by sex worker organizations. For operators, this means: The legal framework from 2017 remains unchanged, but the likelihood of changes in detail is higher in the coming years than it was in the past.
A Sensible Sequence
- Clarify location first. Restricted area? Area type according to BauNVO? Change of use required? Both – municipal authority and building supervision – before the lease agreement.
- Contact the permit authority. District or independent city at the location of the establishment; ask for application forms and template for the operating concept.
- Write the operating concept in detail. Organizational, personnel, spatial, hygienic, safety-related – with verifiable procedures rather than declarations of intent.
- Name individuals. Certificate of good conduct type 0 for applicants and for all those with management or security responsibilities; do not forget notification under Section 25 Para. 2.
- Set up rooms. Emergency call system, doors that open from the inside, sanitary facilities near work and break rooms.
- Establish operating routines. Written agreements, same-day records with two-year retention, condom posting, verification of registration certificates.
- Report changes. New rooms, new form of operation, new management personnel belong to the authority – not in the next inspection.
The definitive information always comes from the competent district or city municipal authority and, for the use of the rooms, from the competent building supervision. Those who involve them early negotiate over conditions. Those who involve them late negotiate over closures.
