How to find active municipal building‑code orders (Nutzungsuntersagung, Bauordnungsbußgeld) and which seller statements you must get

Overview — why this matters

Municipal building‑law orders such as a Nutzungsuntersagung (order to stop or prohibit a use) or ongoing Bußgeldverfahren under state building law can stop renting, force demolition or require expensive remedial work. Courts have held that a seller who knowingly conceals an unauthorised use or a pending bauaufsichtliches Verfahren can face contract rescission or damages (case example: BGH, 6 March 2020). (See sources.)

If you buy from abroad you cannot rely on a one‑line notarial clause alone. You must check municipal public notices, the local Bauaufsichtsamt case file and obtain seller confirmations and documents that prove the property’s lawful status.

Step 1 — Search the municipal 'Amtsblatt' / official notices

Many German municipalities publish decisions, general orders and public service of administrative acts in an online 'Amtliche Bekanntmachungen' or an Elektronisches Amtsblatt. Look for terms: "Nutzungsuntersagung", "Allgemeinverfügung", "Bauaufsichtsbehörde", "Bußgeldbescheid" and the property address or parcel (Flurstück) number. Example municipal pages show published Nutzungsuntersagungen and Allgemeinverfügungen in the public notices listing. (See the Leonberg public‑notice page and the Landkreis Bautzen example.)

If you find an announcement, open it and note the date, Aktenzeichen (file number) and any appeal deadline in the notice. Public‑notice publication often counts as official service to neighbours — that matters for limitation and appeal periods. (See the Landkreis Bautzen example where publication in the Elektronisches Amtsblatt is stated as Zustellung on 12.08.2026.)

Step 2 — Ask the Bauaufsichtsamt for the case file or a written status

Local building‑control offices (Bauaufsichtsamt or Bauordnungsamt) hold decisions, notices and enforcement files. Many counties and cities allow neighbours or interested parties to inspect the full file by appointment; the Landkreis Bautzen website explicitly states that as a neighbour you can view the complete Baugenehmigung and Verfahrensakte at the Landratsamt (arrange a termin). (See source.)

Practical request: send an e‑mail or letter quoting the property address and the Aktenzeichen you found in the Amtsblatt and ask for (a) a copy of the Bescheid(s) (Nutzungsuntersagung, Bußgeldbescheid), and (b) whether the matter is subject to an ongoing enforcement or appeal. If the office refuses, ask for the legal basis for refusal in writing and consult a German lawyer or the notary.

Step 3 — Documents and seller declarations to obtain

At minimum, ask the seller for copies of:

- the original Baugenehmigung (including all Auflagen) and the final building‑inspection note or Nutzungsfreigabe if issued; - any administrative Bescheid that contains a Nutzungsuntersagung or Bußgeldforderung (copy of the Bescheid and the Aktenzeichen); - proof of payment or clearance if a Bußgeld was imposed and paid, or written confirmation of measures carried out to remove an ordered defect.

Additionally, ask the seller to sign a written seller’s declaration (Verkäufererklärung) that specifically states whether they know of any ongoing or threatened bauaufsichtliche Maßnahmen against the property, and to attach the authorities’ decision texts. German legal guidance and notary practice stress that sellers must disclose defects that materially affect the transaction (examples: missing building permit, unlawful use); failure to disclose can lead to rescission or damages (see Notare Bayern press note and the Schleswig‑Holstein chamber guidance). The BGH decision of 6 March 2020 shows courts take nondisclosure of an unauthorised use seriously. (See sources.)

Practical cautions and next steps

Be cautious about relying solely on a notary‑warranty clause. Notarial statements are powerful, but courts will examine whether the seller actually knew of a defect or proceeded in bad faith (BGH case law). If the Bauaufsichtsamt file shows an ongoing enforcement case, pause the transaction until you have written clarifications from the authority and a seller commitment to remedy costs or indemnify.

If you find a public notice but cannot read German, have the notice and any Bescheid professionally translated before relying on it. For legal certainty about seller representations or to enforce indemnities, instruct a German specialist lawyer (Fachanwalt für Bau‑/Immobilienrecht) or ask the notary to add tailored escrow or indemnity clauses in the purchase contract.
