About the statistics

The information under «About the statistics» was last updated 12 February 2025.

Approved building

When project application is granted it is considered as an approved building in the statistics. A granted project application gives permission to start up preparetory work. In cases where the municipality uses a one-step-application (applications where for different reasons there are no need for a two-stepwise executive work; first a general permission and then a project starting permission), the date for general permission is set to be equal to date for the building permit.

Building work started

Building work started. Until 1999 building work was counted as started when the work with piles, the laying of the foundation wall and founding of footing begins. From 2000 the starting date used is the date when the building permit is given.

Buildings under construction

Buildings are considered under construction when the work is reported started but not yet reported completed even when the construction is stopped in the meantime. If a building is still under construction after a mighty long period, an investigation is made to see if the construction is stopped, or if the building is supposed to be completed. The registration is cancelled when a building that is started is not expected to be completed, and the building will not be considered in the statistics. This may affect the numbers.

Buildings completed

A buildings is considered completed when either temporary permission to use is given or when certificate for building accomplished is given. As of 2023M01 the building statistics includes completed buildings that are exempt from applying for a building permit, but must be notified and registered in Matrikkelen.

Rebuilding

New dwellings as a result of rebuilding of existing buildings (i.e. new dwellings due to reconstruction of utility floor space from industry to dwellings). When an old building is being demolished to the foundation wall, it is regarded as a new building. When the building framework is not demolished, it counts as rebuilding.

Buildings demolished

Decrease in number of buildings due to demolition, fire etc. This includes number of dwellings and number of buildings. Buildings with more than one building units will be counted as more than one building when demolished. This also goes for vertically divided houses with 2 dwellings and rowhouses. A part of the decrease in number of buildings is caused by revisions and quailty enhancements of the register. This goes for private garages in particular.

Registered dates

For approved buildings, building work started and buildings completed, dates are used from when the buildings where registered by the municipalities.

Utility floor space

Utility floor space is the floor area measured within the outer walls, defined in Norwegian Standard NS 3940 Area and volume calculations of buildings.

Dwellings

A dwelling is defined as one or more rooms and it must be possible to have access to the room(s) without having to go through another dwelling. Both dwelling units and single rooms are counted as dwellings.

Dwelling units

Dwelling unit is a dwelling with kitchen.

Single rooms

Single room is a dwelling without kitchen or with a shared kitchen.

Dwellings

Dwelling equal dwelling units plus single rooms.

Room

A room must satisfy the room requirements of the Building Act. Kitchen, bath, hallway and the like are not counted as rooms.

Floor

The number of dwellings and area in the basement, lower floor and loft are registered. The difference between basement/lower floor and lower floor/regular floor is stipulated in the building regulations and in principle is determined by how high the panelled ceiling is above level terrain. A regular floor shall have a height of 2.10 metres or more above a breadth of minimum 1.20 metres. An accessible volume above the upper regular floor is called a loft. A free height of 1.90 metre with a minimum width of 0.60 metres is required.

Type of building

The building type is established according to the function of the building. Combined buildings, for instance combined dwelling and business buildings, are classified by the function that occupies the main part of the utility floor space. The building types in the building statistics are aggregated from the detailed classification in the Cadastre.

Industrial classification. In addition to building type, it is also registered what industry the user of the building belongs to. The Industrial Classification is attached to the user and is therefore independent of the building type. At the time of filling out the statistical form it is not always known who the user of the building will be. Because of this the industrial classification is considered to be more uncertain than the classification of the building type. The industrial classification is in accordance with the EU Industrial Classification NACE.
