'My building doesn't exist': Stockholm residents left in limbo as duplicate property images flood city planning database

A retired schoolteacher in Södermalm spent eleven months trying to get a building permit for a bathroom renovation, only to discover that her apartment block on Hornsgatan appeared twice in the Stockholm Stadsbyggnadskontoret's digital planning archive — with different floor plans attached to each entry. The duplicate image had been sitting in the system, undetected, since at least 2019. Her contractor walked off the job. The bank froze her renovation loan pending clarification of the property's legal status. She is still waiting.

Her case is not isolated. Across Stockholm's inner and outer districts, homeowners, tenants and property developers are reporting growing frustration with what city planning administrators have acknowledged is a systematic problem with duplicate cadastral images and georeferenced property photographs inside the municipality's digital records infrastructure. The issue has moved from a technical footnote to a lived crisis for hundreds of residents.

The timing matters. Stockholm's residential property market has been under pressure since the Riksbank began its rate-adjustment cycle in 2023, and transaction volumes in districts like Östermalm and Hägersten have remained sensitive to any friction in the approval pipeline. A delayed permit or a clouded title search, caused by nothing more than a duplicated JPEG in a government archive, can cascade into a failed sale or a stalled construction contract worth hundreds of thousands of kronor.

What residents are actually experiencing

Community meetings held by the tenant association Hyresgästföreningen's Stockholm region branch have surfaced a consistent pattern. Members describe submitting building notification forms — the so-called anmälan process under Plan- och bygglagen — only to receive automated rejections citing mismatched property identifiers. The rejections reference image files that appear to show the correct address but carry the wrong fastighetsbeteckning, the unique cadastral designation assigned to every parcel of Swedish land.

In Vasastan, a property owner on Upplandsgatan described spending roughly 14,000 kronor on architectural drawings that had to be redrawn from scratch after the Stadsbyggnadskontoret confirmed that the reference images attached to his property record belonged to a neighbouring building on Karlbergsvägen. The mix-up dated to a digitisation project completed in 2021, when thousands of analogue archive documents were scanned and batch-uploaded. Some files were tagged to the wrong coordinates during that process.

The city's Lantmäteriet liaison office, which handles the national land registry interface, told callers in several documented cases that corrections require a formal written request, identity verification and, in some instances, a site inspection — a process that can take between six and sixteen weeks depending on workload. For owners trying to close a property sale before a mortgage offer expires, that window is often fatal to the deal.

What the city says, and what residents want

Stockholm municipality's Stadsbyggnadskontoret published a technical notice in May 2026 acknowledging image-metadata inconsistencies in its Bygglov-portalen system and stating that a remediation review was underway. The notice did not specify how many records were affected or set a public deadline for resolution. Residents and advocacy groups have called that level of transparency inadequate.

The Villaägarnas Riksförbund, the Swedish homeowners' association, has urged the city to establish a dedicated fast-track correction desk — similar to a mechanism introduced by Göteborg municipality in 2024 after a comparable digitisation error affected records in the Majorna-Linné district. Stockholm has not committed to that model.

For now, residents facing duplicate-image problems are advised to file a skriftlig begäran om rättelse directly with the Stadsbyggnadskontoret at Tekniska Nämndhuset on Fleminggatan 4, citing the specific fastighetsbeteckning and attaching any original purchase documentation or earlier correspondence. Bringing a printed copy of the conflicting image files, if accessible through the Bygglov-portalen, substantially speeds up initial triage, according to guidance circulated by Hyresgästföreningen.

The schoolteacher on Hornsgatan says she filed that exact paperwork in April. Her correction request is marked as received. The bathroom still has its original 1970s tiles.
