Requesting the information from the Bauordnungsamt yourself
The way without us, step by step
Without us, you apply directly to the Bauordnungsamt Bonn. The city requires an informal e-mail application and describes it like this:
- An e-mail to the general administration and contributions department of the Bauordnungsamt, beitragsabteilung@bonn.de. The city also links a form for encumbrance and contribution information.
- The e-mail states your interest in the property, Gemarkung, Flur, Flurstück, and name and address for the invoice.
- The city gives no information from the register by phone. Appointments in the Stadthaus, Berliner Platz 2: Mondays and Tuesdays 8 to 13, Thursdays 13 to 18, by arrangement only.
- Inspection and extract go through the same office; the city then issues a fee notice.
- Costs compared: 30 euros per parcel without an encumbrance sheet, 50 to 150 euros per parcel for an extract with one. With us 42.90 euros incl. the fee without encumbrance; if one is registered, we name the extra amount before payment. We are not an authority and assess no encumbrance.

The fee depends on the result. Written information that no encumbrance sheet exists costs 30 euros per parcel. An extract from the register costs 50 to 150 euros per parcel, depending on the effort. Several parcels are each charged separately.
In the application you explain your interest in the property. The basis is § 85 (5) of the Landesbauordnung NRW; anyone who shows such an interest may inspect the register and have an extract made. The city sets the fee under the NRW Fees Act.
Questions about building encumbrance information in Bonn
Where do I get a building encumbrance extract in Bonn?
From the Bauordnungsamt Bonn, general administration and contributions department in the Stadthaus, Berliner Platz 2. Apply informally by e-mail, stating your interest, Gemarkung, Flur, Flurstück and billing address. In person only by prior appointment.
What does building encumbrance information cost in Bonn?
If there is no encumbrance sheet, the written information costs 30 euros per parcel. An extract from the register costs 50 to 150 euros per parcel, depending on the effort. With us the information without encumbrance costs 42.90 euros incl. the fee. If one is registered, we name the extra amount before you pay.
Can I get information by phone in Bonn?
No. The City of Bonn explicitly writes on its page that information by phone is not possible. The way is an informal e-mail application with the parcel and invoice details. The result comes in writing, together with the city's fee notice.
Who may inspect the register of building encumbrances in Bonn?
Anyone who shows an interest in the property, e.g. as owner, buyer, seller or architect. So say the City of Bonn's privacy notes on inspection, based on § 85 (5) of the Landesbauordnung NRW. Explain this interest briefly in the application. If you order through us, we submit your statement with your power of attorney.
Do I need the information when buying a house?
You decide that with your notary or bank. An encumbrance is entered in the city's register, and according to the City of Bonn a declaration of encumbrance always binds later owners of the plot too. Buyers can therefore request information in advance. What a registered encumbrance means for your project, we do not assess.
Which details do I need for the application?
Gemarkung, Flur and parcel number, plus name and address for the invoice and a short reason why you need the information. Gemarkung and parcel are in the cadastral map or the land register; the map is available from the Katasteramt Bonn. The city explicitly names all three parcel details as required.
