'My building looks like a stranger's house': Copenhagen residents speak out on duplicate image problem

Hundreds of Copenhagen residents have spent months trying to correct property photographs held in the city's official digital records, after discovering that their homes are illustrated with images of entirely different buildings. The problem, which has surfaced repeatedly in complaints filed with Teknik- og Miljøforvaltningen, the city's technical and environmental administration, stems from a mass digitisation project that imported property images into the BBR — the national Buildings and Housing Register — without consistent quality checks.

The timing matters. Copenhagen's municipal planning office has been moving aggressively toward digital-first permit processing since January 2025, meaning that a wrong image attached to a property record is no longer just a filing quirk. It can stall a renovation application, confuse an insurance assessment, or, in at least a handful of documented cases, send tradespeople to the wrong address entirely.

From Nørrebro to Amager: where the problem hits hardest

The complaints are not evenly spread across the city. Residents on Griffenfeldsgade in Nørrebro and in the newer residential blocks along Ørestad Boulevard on Amager have been among the most vocal in raising the issue with their local councillors. In Nørrebro, where many buildings date to the late 19th century and have been subdivided or renumbered over the decades, the mismatch between a current façade and an archived photograph can span multiple architectural eras. In Ørestad, the problem is different but equally frustrating: buildings completed after 2015 sometimes carry placeholder images of construction-phase hoardings that were never swapped out once the finished structure was handed over.

Grundejernes Investeringsfond, the national property owners' fund, flagged the duplicate image issue in a guidance note circulated to members in March 2026, advising owners to cross-check their BBR entries before submitting any permit application to their local kommune. The fund noted that errors were concentrated in property records that had been migrated from older municipal systems between 2021 and 2023.

People living in affected properties describe a grinding bureaucratic loop. A resident in a co-operative housing association on Frederiksberg Allé — speaking in a general sense representative of complaints logged publicly — described submitting a loft conversion application twice before a caseworker noticed that the reference image showed a completely different building on a parallel street. The corrected record took eleven weeks to update.

What the city says residents should do now

Teknik- og Miljøforvaltningen has published a self-service correction pathway on the borger.dk portal, where property owners can flag image discrepancies directly. The process requires uploading at least two dated photographs and a copy of the BBR extract showing the erroneous entry. According to the portal's own guidance, corrections are processed within eight weeks under normal load — though residents in active planning areas near the Carlsberg Byen redevelopment zone and around the new metro stations at Sydhavn have reported waits closer to fourteen weeks.

The Lejernes Landsorganisation, Denmark's national tenants' union, has advised renters specifically to notify their landlord in writing if they spot a mismatched image on their home's BBR entry, and to keep a copy of the notification in case a future insurance or tenancy dispute requires proof of due diligence. The union estimates — based on its own member enquiries during the first half of 2026 — that the problem affects a meaningful share of older rental stock in the inner city, particularly in Vesterbro and along the streets immediately south of Nørreport Station.

For now, the practical advice from housing lawyers and residents' associations is consistent: check your BBR entry before you need it for anything official. The borger.dk portal allows any property owner or registered tenant to pull up the current record at no cost. If the image is wrong, file the correction request immediately — because the eight-to-fourteen-week clock does not start until the request is in the system. Waiting until a permit deadline is imminent, as dozens of residents have already discovered, makes a frustrating situation considerably worse.
