Addresses

Change history for an address

Everything that has changed at and around the address, newest first: BBR (buildings and units), DAR (the address itself), property valuations, forced sales, local and municipal plans, businesses at the address, shops within 1 km and public transport stops within 500 m. Only meaningful changes — not technical registration versions. The same timeline as the History tab on danskadresseapi.dk.
