SEFRAK is a national register of older building and other cultural heritage objects in Norway. SEFRAK is an acronym for Secretariat for the registration of immovable cultural heritage monuments, which was the name of the institution that started working on the register. Today the responsibility for the registration and maintenance of the data lies with the Directorate for Cultural Heritage. All buildings built before 1900 are supposed to be registered, except ruins. In Finnmark the limit for the latest building date of a building was moved to 1945. Houses in the SEFRAK registry are not considered listed, and there are no specific restrictions on the buildings. The SEFRAK registry does not affect a buildings listing status.
SEFRAK buildings are subject to the same proceedings as any other building. The exceptions are if the SEFRAK building is older than 1850 or if it is protected by law. If the building is older than 1850, it is subject to a conservation assessment to determine if it should be protected by law. If it is already protected by law, it is subject to the same treatment as any other building that is protected by law.
