Construction companies operating in Germany are sometimes confronted — mid-project — by the relevant public order authority (Ordnungsamt) or the chamber of crafts (Handwerkskammer) with allegations of having violated the Handwerksordnung (HwO), Germany’s regulatory framework governing the crafts and trades sector. For those affected, this typically comes as a surprise and frequently causes significant uncertainty in ongoing operations. The consequences for the companies involved can be severe. In addition to fines, they may face interference with existing contracts, financial risk, and reputational damage.

Fines for Alleged HwO Violations — What Construction Companies Now Face
It is therefore important to examine the allegations carefully in these situations. Not every accusation holds up to legal scrutiny, and with the right approach, many proceedings can be significantly defused or resolved.
This article explains the legal background, looks at typical sources of error in practice, and outlines the circumstances in which it may be worth challenging such allegations through legal action.
Investigations by the Ordnungsamt or Handwerkskammer: How Proceedings Begin
Investigations by the Ordnungsamt or the Handwerkskammer can take a number of different forms.
One common scenario is that irregularities are identified during site inspections by the Ordnungsamt — in practice, this is the most frequent trigger. During such inspections, the activities being carried out and the associated responsibilities are examined. At this stage, the authority already begins collecting initial evidence and documentation that may later be used in proceedings. It is therefore important, from the outset, to be careful about what information is disclosed.
If there is sufficient evidence of an HwO violation and the Ordnungsamt is considering taking action, it will typically send the company a written hearing notice, setting out the grounds for suspicion and informing the company that it is considering imposing, for example, a fine. The company is given a deadline within which to submit a response.
Recommendation: It is important not to let this deadline pass and to make use of the right to respond. Seeking legal advice at this stage is often advisable, as it helps avoid contradictions in the company’s own account and prevents the premature voluntary disclosure of important documents.
If doubts remain after the hearing, the authority may go a step further and initiate a business inspection (Betriebsprüfung). This typically goes beyond the specific incident and examines the company’s general activities. The authority may, for example, request specific documents such as order confirmations, internal records, and invoices. It is strongly advisable to seek legal advice before or during this process.
Finally, where particularly serious violations are suspected — such as undeclared work (Schwarzarbeit) — search and seizure measures may be carried out. Legal counsel should be sought without delay at this stage.
Master Craftsman Requirement or Permissible Activity? Why Many Allegations Can Be Challenged
The master craftsman requirement (Meisterzwang) applies only to trades subject to mandatory authorization. These are listed in Annex A to the HwO and generally require a master craftsman’s certificate (Meisterbrief) or an equivalent qualification. Trades that are exempt from authorization — authorization-free trades and craft-like trades — are governed by Annexes B1 and B2 of the HwO. Certain activities that are not “substantial” within the meaning of Section 1(2) HwO may also be carried out without a Meisterbrief.
The scope of trades subject to mandatory authorization — and therefore the Meisterzwang — is frequently interpreted too broadly, with mixed activities being classified as full trades even where only a narrowly defined part of the trade is actually being performed. This can occur, for example, when the assessment focuses solely on the job title without examining whether genuinely “substantial” craft activities are actually being carried out. Certain special authorizations may also be overlooked. Given the difficulty of drawing these distinctions, decisions by the relevant authorities can often be successfully challenged before the courts.
Minor Craft Activities and Non-Substantial Work: Where Authorities Regularly Get It Wrong
Minor craft activities (Minderhandwerk) are activities that, from the perspective of a fully qualified craft business, cover only a peripheral area and can be performed safely after a short period of on-the-job training, without the specialist knowledge acquired through formal craft training. Such activities do not give rise to a registration requirement.
When distinguishing between trades requiring registration and registration-free minor craft activities, authorities regularly fail to recognize that the relevant test is not mere subject-matter proximity to Annex A, but whether the activities constitute the core of the trade in question. A craft business exists only where the activities performed make up the essential core of the relevant trade and give it its defining character.
Activities that, from the perspective of a fully operating craft business, cover only a peripheral area — or that require no specialist knowledge or skills that can only be acquired through formal craft training — do not justify the imposition of a master craftsman requirement. Activities that can be performed safely after a short period of on-the-job training, typically within three months, are defined by law as non-substantial and constitute a minor craft activity within the meaning of Section 1(2) sentence 2 no. 1 HwO. They may therefore be carried out without a master craftsman’s qualification and without registration. A promising line of defense here is to examine the specific activity in detail — its level of difficulty, the training time required, and its position within the occupational profile of the full trade (core area vs. peripheral area) — in order to establish the minor-craft character of the business.
Defective Fine Notices: What the Courts Require
In the crafts context, fine proceedings often fail at an early stage due to formal deficiencies in the fine notices themselves. Section 66 OWiG requires a sufficiently specific description of the alleged offense, identifying the relevant facts by time, place, nature of the service, client, scope, and classification within a particular trade — in enough detail that the identity and extent of the offense are clearly recognizable and cannot be confused with other similar incidents.
Where fine notices are incomplete or insufficiently specific — for example, merely alleging “full-trade activities in the masonry, concrete, and civil engineering sector on a significant scale” without naming specific construction projects or individual services — there are good prospects for successfully challenging them.
Intent Required: Why Not Every HwO Violation Is Subject to a Fine
Violations of the HwO are only subject to a fine where they are committed intentionally, pursuant to Section 10 OWiG. This applies in particular to Section 117(1) no. 1 HwO, which requires intent and therefore leaves room for lines of defense: a person who mistakenly believes that the activities in question — for example, peripheral activities — are not subject to any authorization requirement is not acting intentionally and therefore cannot be held liable as the perpetrator of a regulatory offense.
Managing Director Liability and Business Consequences: When Personal Risk Arises
It is frequently underestimated that managing directors (Geschäftsführer) may also face personal liability. Repeated allegations, organizational failings, or a failure to act on official warnings can ultimately lead supervisory authorities to turn their attention not only to the company but also to the individuals responsible for its management.
What Affected Companies Should Do
A number of clear recommendations can be drawn for companies facing these proceedings:
- Do not make hasty statements to authorities
- Observe all deadlines without fail
- Do not hand over documents without prior legal advice
- Analyze your own activities carefully — does the work fall within the core area of a trade subject to mandatory authorization, or does it constitute a minor craft or non-craft activity?
- Seek legal advice at an early stage
The best legal prospects typically arise where companies begin examining the allegations thoroughly from the outset. In the best case, proceedings may be discontinued under Section 47 OWiG.
