What counts is the date the application reaches the building authority. So as not to disadvantage applicants who applied in time, the city says bringing one forward is not possible even in exceptional cases. Because the register is being digitised step by step, documents are sometimes missing and it can take longer than 6 weeks.
The free phone information on Tuesday mornings is currently suspended: the city's page says that for staffing reasons there is currently no phone information from the register, as of 26 October 2026. If you need the information for a purchase or building application, request it in writing early.
Building encumbrances are not in the land register; the land register at the local court shows ownership, rights and mortgages. The city keeps the encumbrance register for all properties in Duisburg with registered encumbrances.
Questions about building encumbrance information in Duisburg
How do I get information from the building encumbrance register in Duisburg?
In writing or by email from the lower building authority of the City of Duisburg, bauaufsicht@stadt-duisburg.de. State Gemarkung, Flur, parcel and street. The decision comes in writing. The phone information on Tuesdays from 9 to 12 is currently not offered for staffing reasons.
What does building encumbrance information cost in Duisburg?
The city charges fees for written information under the NRW general administrative fee regulation, but states no amount on its page. Phone information would be free but is currently suspended. With us the information costs 42.90 euros including a fee up to 15 euros; you only pay more per the decision.
How long does an extract from the register take?
In Duisburg generally about 6 weeks, processed by date of receipt. Because the city is digitising the register step by step, it can take longer. Applications cannot be brought forward, not even in exceptional cases, so applicants who applied in time are not disadvantaged. Plan the waiting time before a notary appointment.
Can I get the information by phone?
Not at the moment. Normally the City of Duisburg gives free phone information on Tuesdays between 9 and 12 on 0203 283-986703. The page currently says there is no phone information for staffing reasons. The written route remains.
Which property data does the building authority need?
The City of Duisburg requires Gemarkung, Flur, parcel and street. Gemarkung, Flur and parcel are on the land register printout or the cadastral map. The city's page lists exactly these four items as required property data. You get a cadastral map from the city's cadastre office.
Are building encumbrances in the land register?
No. The land register at the local court shows owners, encumbrances and restrictions such as rights of way, plus land charges and mortgages. In Duisburg the city keeps building encumbrances in its own register for all properties with registered encumbrances. For a purchase you therefore need both pieces of information separately.
