Berlin and Frankfurt am Main, Germany
Germany's land register opens only to someone who can show a legitimate interest, so in Berlin and Frankfurt the owners who can be named are the ones who name themselves — pension funds, insurers, listed landlords and the state — while a city-wide majority voted in 2021 to expropriate the largest of them and no flat has changed hands because of it.

Can you find out who owns it?
Ownership in Germany is recorded in the Grundbuch kept by each Amtsgericht, and § 12 of the Grundbuchordnung limits who may look: 'Die Einsicht des Grundbuchs ist jedem gestattet, der ein berechtigtes Interesse darlegt' — inspection is open to anyone who demonstrates a legitimate interest, which curiosity, research and journalism are not. The federal-state justice portal says the same of the electronic route: 'Die Einsichtnahme ist kostenpflichtig und an die Erfüllung von Zulassungskriterien geknüpft.' The fees, once admitted, are small — EUR 10 for a plain Grundbuch printout and EUR 20 certified (GNotKG KV 17000–17001), EUR 8 per Grundbuchblatt retrieved electronically (JVKostG KV 1151) — but there is no bulk product and no sales list. What is open is value, not ownership: each city's Gutachterausschuss publishes Bodenrichtwerte (standard land values per zone, free in Berlin's BORIS and Hessen's open geodata) and aggregated market reports built from every notarised sale, never naming a party or a parcel. Berlin and Frankfurt share one regime and are one record here; every building and figure below says which city it belongs to.
Is ownership public?Only for those who can prove a legitimate interest
Cost of one title searchEUR 10 unbeglaubigter Grundbuchausdruck, EUR 20 beglaubigt (GNotKG KV 17000/17001); EUR 8 per Grundbuchblatt by electronic retrieval (JVKostG KV 1151) — all conditional on a berechtigtes Interesse under § 12 GBO

The marquee buildings
The towers that set the tone of the core, and who holds them. A price is the price a document states, on the date it states — not an estimate of what the building is worth now.

| Commerzbank Tower Kaiserplatz / Große Gallusstraße 17-19, 60311 Frankfurt am Main — Innenstadt |
Office | Not established the jurisdiction does not disclose owners Frankfurt. Germany's tallest office building (259 m). The pack named 'Commerzbank AG (owner-occupier)'; that is not supported. Search-engine entries for the bank's own newsroom carry a release of 30 September 2016, 'Commerzbank sells Commerzbank Tower to Samsung SRA Asset Management', describing a sale with a 15-year lease-back — but both indexed newsroom paths now 404 and the IR host is an unreadable JavaScript shell, so the release could not be opened and no owner is asserted. The Grundbuch entry that would settle it is closed to anyone without a berechtigtes Interesse (§ 12 GBO). What is certain is only that the pack's answer was the tenant. |

| MAIN TOWER Neue Mainzer Straße 52-58, 60311 Frankfurt am Main — Innenstadt |
Office | Not established the jurisdiction does not disclose owners Frankfurt. The tower's site is published 'Im Auftrag der Landesbank Hessen-Thüringen Girozentrale', which gives 'MAIN TOWER, Neue Mainzer Straße 52-58' as its own registered seat; the same site lets 'Büroflächen vom 2. bis 52. Stockwerk' through named Helaba Immobilienmanagement staff and runs the public viewing platform at 192 and 198 m. None of the pages opened — Entstehung, Zahlen, Geschichte, Gebäudekonzept, Impressum — contains the word Eigentümer, and Helaba's own locations page 404s on the tower. Letting and occupying are not title, so the owner is left blank; Helaba is recorded as operator and headquarters tenant, which is what its pages state. |

The core land
The most valuable ground in the city, and what the public record says about it.
In a closed-register country the public record of 'who owns the city' is political and corporate rather than cadastral. Berlin's 2021 referendum put a number on how many citizens wanted the largest landlords expropriated; the state's six housing companies and the listed landlords put numbers on how much they hold; the Gutachterausschuss puts numbers on land values and total turnover — and no public document puts a name on a parcel.
Volksentscheid 'Deutsche Wohnen & Co enteignen', 26 Sep 2021 (Berlin)Ja 1,035,950 (57.6%) — Nein 715,698 (39.8%)
Landeswahlleiterin Berlin, amtliches Endergebnis: quorum 611,900 (25% of the 2,447,600 entitled), valid votes 1,751,648; 'Der Beschlussentwurf ... wurde angenommen.' The vote asked the Senate to prepare expropriation of landlords with more than 3,000 flats.
What followed the referendum (Berlin)No expropriation; framework law passed Mar 2026, in force two years after promulgation
Chronology as published by Deutsche Wohnen (Vonovia): Senate expert commission report June 2023 found the project 'mehrheitlich als verfassungsrechtlich zulässig'; the initiative tabled its own bill in Sep 2025; the CDU/SPD coalition's Vergesellschaftungsrahmengesetz was introduced Dec 2025 and 'im März 2026 verabschiedet', deliberately entering force two years after promulgation pending a Bundesverfassungsgericht review. The Senate's own commission site is 410 Gone.

Stated on STADT UND LAND's site: 'Bereits zum 31. Dezember 2025 lag ihr Bestand bei 404.170 Wohnungen' (the Land's target 'Wohnungen im Landeseigentum' reached early).

Who builds the houses
New-home building in this market: the volume, and the firms behind it. Ownership of a builder matters as much as its volume — a private-equity platform and a family firm behave differently.
There is no German builder league table, and Destatis/AfS completions pages could not be opened, so the table is built the only way Germany allows: from what landlords state about their own stock. Berlin is a landlord city — six state-owned companies hold 404,170 flats and Vonovia's Deutsche Wohnen about 100,000 more, which is why a referendum, not a sales register, is the city's defining ownership document. Frankfurt's counterpart is the city-owned ABG with about 55,000 flats and the Land's Nassauische Heimstätte | Wohnstadt with 61,000 across Hessen. Each figure says which city.

Commercial landlords
The commercial side, counted separately from housing: who holds the office, retail and industrial floor area.
Commercial ownership in both cities is disclosed only by the owners that are listed, regulated or foreign: insurers and pension funds buying towers forward, open-ended funds, and a handful of listed landlords whose asset lists name the city. The Gutachterausschüsse count every sale but publish none.

Looked for and not found
Claims this page would have made if a source could be opened. They are left out rather than guessed.
- The current owner of the Commerzbank Tower: the bank's indexed 2016 release describes a sale to Samsung SRA Asset Management with a 15-year lease-back, but it could not be opened on any Commerzbank host; the pack's 'Commerzbank AG (owner-occupier)' is in any case contradicted by that snippet.
- Whether Helaba owns MAIN TOWER or occupies it: its site operates and lets the tower and gives it as the bank's seat, but no opened page says Eigentümer.
- Berlin's 2025 Geldumsatz and number of Kauffälle: the Gutachterausschuss publishes them as PDFs (Vorläufige Jahresumsätze 2025, 21 Apr 2026; Immobilienmarktbericht 2025/2026, 31 Jul 2026) that returned 429 to this research.
- A numeric top Bodenrichtwert for either city: BORIS Berlin and BORIS Hessen are browser applications and the guessed Berlin WFS endpoint 404s.
- Berlin and Frankfurt housing completions (Baufertigstellungen): the statistics offices' pages could not be opened.
- Vonovia's own Berlin unit count (as distinct from Deutsche Wohnen's c. 100,000) and whether the 471,000 group figure is as at the same date; its regional and portfolio pages 404.
- The Potsdamer Platz quarter (The Playce): listed on BGRE's homepage carousel, but no deep page states whether BGRE owns or manages it, and potsdamerplatz.de's impressum names only a Verwaltungs GmbH.
- Omniturm, Messeturm, Deutsche Bank towers, Opernturm, Taunusturm (Frankfurt) and Alexa, Mall of Berlin, Upper West, Fernsehturm (Berlin): no owner source opened; the Grundbuch cannot be consulted without a berechtigtes Interesse.
