Seismic risk in Bucharest

Bucharest's red-dot buildings, one by one

The official list of assessed buildings has 2,798 addresses. We placed 2,626 of them on their own outlines, at their own heights, in today's city. The map also shows where the list stops.

415 buildings are in class RsI, the one marked with a red dot: their expertise found them liable to collapse, wholly or in part, in the design earthquake. The class does not say when an earthquake will come. The list records 6,586 flats in them; for 49 the number is missing.

1,455 buildings, 52% of the list, have no risk class under today's rules. They carry only an 'urgency category' assigned between 1991 and 1997 under rules since repealed.

Near 23 of the 27 central sites where blocks fell in 1977, less than 100 metres away, we mapped an RsI building of today.

The city with every red dot#

Each coloured building is an address on the list. Grey are buildings with no row on the list; the map cannot tell whether they were ever assessed. Outlines come from OpenStreetMap; heights are estimated from the number of storeys.

This is the whole list, as much of it as we could map: 2,626 of 2,798 buildings. The rest have addresses we could not place with certainty. They are in the table at the end, without a point on the map.

Class RsI only: 415 buildings, 404 on the map. 337 of them are in sectors 1, 2 and 3, and for 381 the list gives a construction year of 1940 or earlier.

A red dot does not mean a tall block. 206 RsI buildings have a ground floor and at most two storeys, like these in the Old Town, on Lipscani and Franceză. Only 90 have seven levels or more.

The 90 with seven levels or more are mostly old blocks. You find them on Calea Victoriei, on Regina Elisabeta and Kogălniceanu, on Carol I, on Bălcescu, and on the streets around them.

In white: where blocks fell on 4 March 1977. Near 23 of them, less than 100 metres away, there is a red-dot building today. That is proximity on a map, not a forecast.

Purple: 1,455 buildings with only an 'urgency category', U1, U2 or U3, assigned between 1991 and 1997. The code set a deadline for strengthening: 2, 5 or 10 years. The last were assigned in 1997, 29 years ago. Of 476 re-assessed by 2022, 347 came out RsI; they are not a random sample.

The list records 118 buildings strengthened since the 1990s. In 2024, according to the head of AMCCRS, only 30 had been strengthened with public money.

And the rest, in grey. For a building not on the list, we don't know whether it was ever assessed; that does not make it safe. In 2024 the head of AMCCRS quoted a World Bank estimate: about 20,000 vulnerable buildings built before 1977. It is an estimate by building type, not an expertise.

What is on your street#

Type a street or a public institution. You see the listed buildings, the institution's address and whether it is on the seismic list. Institution names are in Romanian. The institution list comes from OpenStreetMap, with a few major offices added by hand, and is incomplete. The page shows list data, not the expertise report or the building's condition today: for that, ask your building manager or AMCCRS for the report.

What the classes mean#

A class is set only by a technical expertise from a certified engineer. Law 212/2022 defines them by what would happen in the design earthquake, the strong quake new buildings are calculated for.

  • RsI

    May collapse, wholly or in part. City Hall must put a notice panel at every entrance of a residential building in this class: that is the 'red dot'. From notification, owners have two years to get a strengthening design and, from its approval, two more to start work. The map shows the class on the list; it does not check whether the panel is up.

  • RsII

    Major damage that endangers people, but collapse is unlikely.

  • RsIII

    Moderate damage that may endanger people.

  • RsIV

    Behaves like a building designed to today's codes.

  • U1, U2, U3

    1990s codes under repealed rules: deadlines for strengthening of 2, 5 or 10 years. City Hall says they cannot be converted automatically into RsI–RsIV. A new expertise is needed.

  • Strengthened

    Buildings whose strengthening works are finished.

  • No clear classification

    The list gives neither a risk class nor an urgency category, or the classification field is unclear. Discrepancies are explained beside the address.

The list has 415 RsI buildings in October 2026, compared with 363 in 2022, 390 in 2024 and 415 in May 2026. Part of the growth comes from buildings in the urgency category that finally got a new expertise.

What the list misses#

  • RsI (red dot) 415
  • RsII 491
  • RsIII 163
  • RsIV 11
  • Urgency U1 259
  • Urgency U2 538
  • Urgency U3 614
  • Urgency, no single code 44
  • No clear classification 145
  • Strengthened 118

The list has 2,798 buildings. City Hall itself says the city has no real inventory of its buildings. The World Bank estimate quoted by the head of AMCCRS puts the number of vulnerable pre-1977 buildings at about 20,000. Data exists for about 2,000.

In 2023 City Hall announced a rapid visual assessment of more than 20,000 buildings. The municipal programme that started in 2026 covers more than 6,000, in the centre and the middle ring. A visual assessment gives no risk class; it only says where an expertise should come first.

The capital's 2026 risk analysis and coverage plan, approved by HCGMB 460 on 30 September 2026, calls its 17 April 2026 list of assessed buildings 'a representative but incomplete sample'. The worst case it cites, from the national post-seismic response concept (IGSU, 2021) and computed with SeisDaRo v3 (INCDFP) plus Ro-Risk data, estimates 838 to 33,569 heavily damaged residential buildings in Bucharest for a 7.4–8.1 Mw Vrancea quake.

So grey, on the map, means 'we don't know'. Not 'safe'.

Sleeping in a Bucharest Airbnb? Check the building after booking#

In July 2026, The Guardian reported on an end-of-May analysis by the Romanian organisation Re:Rise: at least 207 tourist-rental listings in Bucharest — on Airbnb and Booking.com, with room for more than 1,000 guests a night — inside buildings in class RsI, the highest seismic risk class. Romanian law prohibits renting residential units in them, yet only two of the verified listings mentioned the risk.

If you already booked, you have the exact address: type the street in the search above and check the building's colour and class. Red means RsI: its expertise found it liable to collapse, wholly or in part, in the design earthquake. Purple (U1–U3) means a 1990s assessment with no current class. Grey means the building is not on the list — which does not mean it is safe.

Two warnings. Airbnb makes the full address available once your reservation is confirmed, so check then. And the red-dot notice at the entrance is in Romanian, which leaves foreign visitors unable to read the warning. This page shows the official list, not the building's condition today.

How the map was made#

We looked up each address on the AMCCRS list among OpenStreetMap's addresses: same street, same number, in the sector the list gives. No position is guessed or interpolated. For '11–13' we looked first for the whole range as OpenStreetMap writes it, then for each end. When the same number exists on two same-named streets of different kinds (e.g. a Strada and an Aleea), we keep the list's kind. When the number turned up in several places far apart, the building stayed in the table only. We fixed 17 spelling differences by hand, such as 'Batiste' and 'Batiștei'. Where we found no address, we used the hand-verified points of DupăCutremur (Re:Rise and geo-spatial.org, CC BY 4.0) with the same street, number and sector, or with the same AMCCRS row number, confirmed by street, number and sector; where both placed the same building, the median gap between the points is 7 metres.

That put 2,626 of 2,798 buildings on the map. Each took the outline of the OpenStreetMap building the address falls in, or the nearest one within 12 metres; 27 without one appear as a 14-metre square. Height comes from the list's own storeys: 4.2 metres for the ground floor and 3.1 metres per storey. Where list and map do not line up perfectly, the outline may belong to the building next door; the row on the list is still the right one.

If a building landed on its neighbour's outline, Report an error.

Spotted a mistake?#

Over two thousand addresses have been placed on the map automatically: sometimes an address pin lands on the neighbouring building's outline; sometimes a row is misread. If you spot something wrong, write to me — the email draft opens with the building's address already filled in. Tell me what is wrong and, if you know, what the correct information should be.

I can correct the map position and errors on the page. The risk class comes from AMCCRS's official records, so I can't change it. If you have questions about your building's seismic assessment, ask your building manager for the assessment report or contact the relevant city hall.
