The Central Register of Buildings and Dwellings (BBR) specifies the property owner, the address and the physical condition of all buildings including installations, drainage and the number of bathrooms etc. Data is used for billing purposes for installation owners, such as state, regional and municipal authorities as well as utility providers and private companies, such as property companies and mortgage banks.

The Danish tax authority is responsible for the registry, and the municipalities maintain the registry information on behalf of the owners. Owners are required to keep the registry current with the actual physical condition.

Netcompany has been system vendor since 2015. In 2017 Netcompany launched a completely new digital register for buildings, commercial and technical infrastructure and private homes.

The BBR project is a keystone in Denmark’s foundational ‘Basic Data Program’ with which basic registrations about Denmark and its citizens are combined under the common term ‘basic data’. This means that data is standardised so it can be combined and used coherently. It gives the public sector a better starting point for making its administration more effective and delivers significant economic benefits. At the same time, private businesses are given the opportunity of using free basic data in developing new, smart solutions and products.
