Site plan (simple or qualified)

For the realization of your construction project, you usually need a building permit. For this purpose, a building application must be submitted in accordance with the requirements of the Lower Saxony Building Code (NBauO) to the corresponding (lower) building supervisory authority or .dem responsible building authority (city, municipality or district). If necessary, simple or qualified site plans must be submitted with this building application in accordance with the Building Template Ordinance (NBauVorlVO).

As a rule, a simple site plan is sufficient. The simple site plan consists of a property map on a scale of 1:500 and a descriptive part. It shall contain the following information:

  • indication of the scale and the location of the property in a northerly direction,
  • Designation of the building plot by municipality, street, house number, land register, district, field, parcel with details of the owners or the hereditary building rights
  • the area of the building plot
  • the cadastral boundaries of the building plot and the neighboring plots
  • the existing buildings on the building plot and on the neighbouring properties
  • Indications of construction encumbrances and
  • References to pending land planning procedures and the executing body.

The submission of a qualified site plan is required, for example, in the case of border development or when maintaining boundary distances. In addition to the simple site plan, the qualified site plan contains the following information:

  • The dimensions of the building plot required for the building authority assessment according to the real estate cadastre,
  • a statement about the reliability of borders and their recognizability in the locality,
  • a statement on the completeness of the building stock,
  • the designation of the neighbouring parcels by specifying the municipality, the land register, the district, the parcel and the parcel number with the indication of the owners or leaseholders.

The decision on which type of site plan is to be attached to a building application is made by the relevant building supervisory authority

Process flow

The site plan can be used with a few details such as e.g. the location of the building plot and the construction costs of the construction project. In the first step, the quality of the property graphic is then checked for the building plot; if the quality is inadequate, existing surveying documents are evaluated and the property graphics are improved accordingly. In the second step, the excerpts from the property graphic and the property description are compiled, processed and sent.

Who should I contact?

Further information can be obtained from the contact persons in the respective cadastral offices of the responsible regional directorates of the State Office for Geoinformation and Surveying Lower Saxony (LGLN) or from a publicly appointed surveyor (ÖbVI).

You can submit an application for the creation of a site plan if you

  • an architect or other person with the power of attorney or consent of the owner or the person entitled to a heritable building,
  • property owner or
  • a person entitled to a hereditary building


Which documents are required?

  • Statement from the lower building supervisory authority as to whether a simple or qualified site plan is required
  • Official address or cadastral designation/parcel identifier of the land on which the new construction project is to be built.
  • Production costs and type of construction project
  • If the applicant is not at the same time the owner or leaseholder, an informal power of attorney from the property owner or the hereditary building owner is required.
  • If the applicant is not also liable for costs, an informal confirmation is required to cover the costs.

What are the fees?

The fees are based on the cost schedule for cadastral surveying (KOVerm). This cost schedule is binding for the regional directorates and for the publicly appointed surveyors.

For a single-family house with a production value of up to €300,000, fees of around €250 are due for a simple site plan (in four copies).

A qualified site plan costs around €785 for the example.

What deadlines do I have to pay attention to?


Processing duration

Duration up to 5 working days.

The qualified site plan takes a much longer period of time due to its required field service component (checking the local conditions and the information provided by the real estate cadastre); As a rule, it is available after three weeks.

What else should I know?

The term site plan is often used synonymously for an ordinary excerpt from the property map: Therefore, it must be clarified in advance with the building supervisory authority whether an excerpt from the property map is sufficient or whether an official site plan is required in connection with a construction project.
