The official site plan is, for example, a component of a building permit application. Upon request, the building authority prepares this as an extract from the city base map. The city base map is based on the official cadastral map maintained by the state’s surveying and cadastral administration and supplements it with planning-relevant details of the city’s topography. We prepare the official site plan for a building permit application at a scale of 1:500; other standard scales are also available (see examples below).
The Building Authority of the City of Mainz prepares site plans exclusively for the urban area of the state capital Mainz (including its districts).
You also have the option to submit a request with details regarding the cadastral district, parcel, parcel number, or street and house number, as well as your personal information and billing address. This can be done via
We typically send the site plan in PDF format via email. Alternatively, we can mail it to you, or you can pick it up in person.
Important Information Regarding Applications for Proof of Ownership
When planning offices (architects) request a site plan with proof of ownership for a building application to be submitted, they act as authorized representatives of the parties responsible for the construction.
For other inquiries regarding owner information in connection with a site plan, as stipulated in Section 13(2) of the State Law on Official Surveying (LGVerm), a legitimate interest in obtaining this data must be demonstrated.
For all other inquiries regarding owners, please contact the responsible Rheinhessen-Nahe Surveying and Cadastral Office.
