You can obtain information from the purchase price collection of the expert committee for property values. The provision of information from the purchase price collection is subject to certain conditions.

When a building is completed, it must be officially measured and the result of the survey entered in the official proof of the real estate cadastre.

All building owners are required by law to have any building officially surveyed. (§ 11 Surveying and Cadastral Law)

The completeness of the building record in the real estate cadastre serves in particular the requirements of planning and land readjustment, the determination of property values as well as environmental and nature protection.

The land use plan reflects the use planned under building law for the entire urban area. The land use plan is a preparatory land-use plan. If information on the possible structural use of a property is required, the development plan is to be consulted .

The Senator for Environment, Construction and Transportation makes the land-use plan available online at www.bauleitplan.bremen.de free of charge.

You can obtain a paper version for 10.00 euros from the Plan Service in the Service Center Construction .

The land-use plan is open to citizens to express and discuss during early citizen participation. During the later one-month public interpretation, it is possible to obtain information on the intended urban development and to submit comments. Once the land-use plan has been announced, the citizen may obtain information at any time.
Children and young people are also part of the public.

The public has the opportunity to comment on and discuss the land use plan during the early public participation period. During the subsequent one-month public display, citizens have the opportunity to obtain information on the intended urban development and to submit comments. After the land use plan has been published, citizens can obtain information at any time.
Children and young people are also part of the public.

The land use plan contains the urban development uses intended by the planning municipality and differentiated for the individual areas (e.g. residential development areas, commercial development areas, traffic areas, green areas, forest areas, agricultural areas). The land use plan does not develop any direct legal effects vis-à-vis the citizens. No legal claims can be derived from its graphic and textual representations, in particular, for example, the right to a building permit for a specific property or claims for compensation. However, the land use plan represents planning for the administration and other authorities, to which they must adapt their planning.
The representations of the land use plan are the basis for the creation of development plans, which contain legally binding determinations vis-à-vis all citizens.

The land use plan contains the urban development uses (e.B. residential areas, commercial building areas, traffic areas, green areas, forest areas, agricultural land) that are wanted by the planning municipality and differentiated for the individual areas. The land-use plan does not develop any direct legal effects on citizens. No legal claims are to be derived from his drawing and textual representations, in particular the right to a building permit for a particular property or compensation claims. However, the land use plan is a plan for the administration and other authorities to which they have to adapt with their plans.
The presentations of the land use plan are the basis for the preparation of development plans which contain legally binding determinations for all citizens.

If the broad outlines of the intended urban development in a municipality are to be changed on a large scale and if the new spatial allocation of the different types of land use is to be expected and reassessed, the existing land use plan must be repealed by the municipality. However, the complete repeal of the land use plan is extremely rare because it no longer provides the basis for developing development plans. As a rule, land-use plans are modified or supplemented when there are some or more changes to a manageable extent.
The repeal is subject to the provisions of the Building Code, which also apply to the establishment, amendment and amendment.

If the basic features of the intended urban development in a municipality are to be changed on a large scale and considerable effects are to be expected and re-evaluated as a result of the new spatial allocation of the various types of land use, the existing land use plan is to be cancelled by the municipality. However, the complete repeal of the land use plan is extremely rarely practiced because it means that the basis for the development of land use plans no longer exists. As a rule, land use plans are amended or supplemented if a few or several changes of a manageable scope are involved.
The regulations of the Building Code, which are also applicable to the preparation, amendment and supplementation, apply to the cancellation.

If the municipality wishes to change the type of planned land use (e.g. residential development areas, commercial development areas, traffic areas, green areas, forest areas, agricultural areas) in one or more sub-areas of the municipality's territory, it must amend the existing land use plan.

In a land use plan amendment procedure, citizens and authorities are informed and involved about the changed planning intentions regarding the type of land use (e.g. residential building areas, commercial building areas, traffic areas, green areas, forest areas, agricultural areas) in a procedure prescribed by law. Frequently, several changes are combined in one amendment procedure. During the early public participation and the public display of the amended planning documents, citizens have the opportunity to obtain information on the planned amendments and to submit comments.

If the municipality wants to change the type of land use in one or more sub-areas of the municipality (e.B.g. residential areas, commercial building areas, traffic areas, green areas, forest areas, agricultural land), it must amend the existing land use plan.

In a land use plan amendment procedure, citizens and authorities are informed and involved in a procedure prescribed by the legislator on the changed planning intentions for the type of land use (e.B. residential areas, commercial building areas, traffic areas, green areas, forest areas, agricultural land). Often, several changes are summarized in one change procedure. Citizens will have the opportunity to obtain information and comments on the proposed changes during early public participation and public interpretation of the amended planning documents.

The Offices for Digitization, Broadband and Surveying are required by law to also document the current building stock in the real estate cadastre. A map of property boundaries without buildings on it would also be of limited use.
