Buenos Aires, Argentina
Buenos Aires sells its land register one property at a time: anyone may buy an Informe N° 1 naming the titleholder of a flat or building for ARS 6,000 online, but only with its matrícula, and the City's open parcel map carries no owners.

Can you find out who owns it?
Title in the City of Buenos Aires is recorded by the Registro de la Propiedad Inmueble de la Capital Federal (RPI), a national registry under the Ministry of Justice. Its web service is open to the 'público en general': an Informe N° 1 (Dominio y Gravámenes) gives the inscribed titleholder and any mortgages, usufructs or embargoes, for 20 modules (ARS 6,000 from 3 Aug 2026), but you must first know the property's matrícula — an Informe N° 4 (also ARS 6,000) finds it from the street address. There is no bulk owner file; the City's cadastre publishes every parcel's polygon openly (CC BY 2.5 AR) without any owner. Sales are published only as aggregates — monthly counts of notarial deeds and average asking prices per m² by neighbourhood (IVC on BA Data) — never per property.
Is ownership public?Public, but one paid search at a time

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.

| 261 Della Paolera (Catalinas Norte) Carlos M. Della Paolera 261, Catalinas, Retiro, City of Buenos Aires 35,208 m² GLA (IRSA owns 3,740 m²) · 30 floors |
Office | Divided ownership by floor; IRSA Inversiones y Representaciones S.A. retains 3 floors 3,740 m² of c. 35,000 m² GLA (30 Jun 2025) IRSA built 261 Della Paolera on 'the last vacant land plot of Catalinas Norte' and inaugurated it on 29 Apr 2021: 30 office floors, 35,208 m² GLA, 316–318 parking spaces, LEED Gold. It has sold floors since — about 9,500 m² in FY2023, 3,579 m² in FY2024, 1,197 m² in FY2025 — and 'retains its rights for 3 floors' (3,740 m², 100% leased). The buyers of the other floors are not named in the filing. IRSA's own head office is on the 9th floor. |

| Ramblas del Plata (former Costa Urbana / Solares de Santa María) Costanera Sur, south-east of Puerto Madero, City of Buenos Aires 70 ha; 184,813 m² land reserve; c. 866,806 m² buildable |
Land | IRSA Inversiones y Representaciones S.A. 100% IRSA's 20-F: 'We own an important 70-hectare property facing the Río de la Plata in the south of Puerto Madero', held since Jul 1997; a City law of Dec 2021 zoned it 'U73' for mixed use, with 50.8 ha (about 71%) given over to public use. IRSA has been selling and bartering lots of the first phase: 6-Ks of 13 Feb, 4 Mar, 26 Jun, 30 Jul and 31 Aug 2026 report barter agreements of USD 6.357M, 4.98M, 14.175M, 4M and 6.7M.

| Costa Salguero (Sector 5, Distrito Joven – Costanera Norte) Av. Rafael Obligado (Costanera Norte), Circ. 19, Secc. 15, Manz. 184, City of Buenos Aires |
Land | Gobierno de la Ciudad Autónoma de Buenos Aires (dominio público) Not sold. The City's joint Resolution 43/MJGGC/25 (19 Dec 2025) describes Costa Salguero as 'espacios pertenecientes al dominio público de la Ciudad' and awards a 10-year public-works concession for design, building and commercial use to the UT Publirevistas S.A.U. – Arte Gráfico Editorial Argentino S.A. at an initial canon of ARS 240,000,000 a month (base ARS 120M); La Rural S.A. bid ARS 310,114,014 but lost on scoring and its challenge was rejected. A 2020 plan to sell the land was halted by a court order; the prompt's 'City sale' could not be confirmed. |
Government | —A |
| Teatro Colón Cerrito 628, San Nicolás, City of Buenos Aires |
Civic | Gobierno de la Ciudad Autónoma de Buenos Aires — Ente Autárquico Teatro Colón City Law 2.855 (2008) creates the Ente Autárquico Teatro Colón within the City's Ministry of Culture, charges it to 'preservar y custodiar el patrimonio arquitectónico' of the theatre, and by its first transitional provision transfers to it 'el patrimonio, presupuesto y personal' of the former Dirección General Teatro Colón. The theatre's own history page dates the municipalisation of the Colón to the 1920s–30s and records the City's 2000 master plan for restoring the building. Tier B: the law transfers assets to the Ente but does not recite the title. |
Government | —B |
| Casa Rosada (Casa de Gobierno) Balcarce 50, Plaza de Mayo, Monserrat, City of Buenos Aires |
Civic | Estado Nacional (Presidencia de la Nación) The Presidency's own site describes the Casa Rosada as the seat of the national Executive, built on the plot that has housed Buenos Aires' successive governing authorities since the 16th-century fort; the Museo Casa Rosada occupies the subsoil galleries over almost a whole block on Paseo Colón. It does not recite a title; the State's ownership is inferred from its use as the seat of the Poder Ejecutivo Nacional, hence tier B. |
Government | —B |
| Retiro Mitre railway station (and the San Martín and Belgrano terminals) Av. Ramos Mejía 1340/1402, Retiro, City of Buenos Aires |
Civic | Estado Nacional — railway infrastructure administered by ADIF (Administración de Infraestructuras Ferroviarias) The national monuments commission's page records Retiro (Ferrocarril Central Argentino, later Mitre), built 1909–15, as a Monumento Histórico Nacional (Decreto 262/1997). Law 26.352, art. 3, gives ADIF 'la administración de la infraestructura ferroviaria' and assigns railway land released from rail use to the AABE; the operator, Trenes Argentinos Operaciones, administers what ADIF assigns it. The law speaks of railway assets 'cuya titularidad ostenta el Estado Nacional'. No register extract was bought, hence tier B. |
Government | —B |
| Aeroparque Jorge Newbery Costanera Norte, Palermo, City of Buenos Aires |
Civic | Estado Nacional (concession to Aeropuertos Argentina 2000 S.A. to 2038) Corporación América Airports' 20-F for 2025 says Aeroparque is Argentina's busiest airport (17.8M passengers in 2025) and is run under the AA2000 Concession Agreement, which began in 1998 and runs to 2038 after the Dec 2020 extension; AA2000 pays the State 15% of revenues, and the State may buy the concession out. CAAP indirectly owns 85% of AA2000 and the Argentine Government 15%. The filing describes a concession to operate, not ownership of the land, so the State as landowner is tier B. |
Government | —B |
| Puerto Madero (the docks district) Diques 1–4, Puerto Madero (Comuna 1), City of Buenos Aires 170 ha |
Mixed use | Not established a paid title search would answer it Puerto Madero's 170 ha were transferred by the Nation to Corporación Antiguo Puerto Madero S.A., a company set up on 15 Nov 1989 by two national ministries and the City as equal partners, which then deeded the plots to private buyers; a court later held that 20,000 m² (the Colegio Nacional de Buenos Aires sports ground) belongs to the UBA. The towers are therefore owned plot by plot and, mostly, floor by floor; each title is a paid RPI search. The Corporation's own site (cpm.ar) was not read: its robots.txt sets a 03:00–12:00 UTC visit window and 3–6 requests an hour. Tier B: Wikipedia (CC BY-SA 4.0). |

| Madero Office (Dique IV, Puerto Madero) Bv. Cecilia Grierson 355, Puerto Madero, City of Buenos Aires 64,800 m² · 26 floors |
Office | Not established a paid title search would answer it RAGHSA's own portfolio page: a 64,800 m² AAA office building on Dique IV with 26 floors of 1,228 m², 571 parking spaces, the first LEED-certified building in Argentina; 'Commercial status: 89% sold; 11% available for lease (1 floor)'. So it is a commercial condominium: RAGHSA S.A. (listed on BYMA) keeps about one floor, and the buyers of the other floors are not named by any source opened. Each unit's titleholder is a paid RPI Informe N° 1. |
Not established | —A |
| Centro Empresarial Libertador Av. del Libertador 7208, Núñez, City of Buenos Aires 100,000 m² total · 26 floors |
Office | RAGHSA S.A. RAGHSA's portfolio page calls Centro Empresarial Libertador its largest development, 100,000 m² in total, an AAA corporate tower 'for lease' with 26 column-free floors of 1,250–2,900 m², 27 lifts and 850 parking spaces, opened 2020, LEED Core & Shell Gold, '100% leased'. The company page calls it 'Argentina's largest AAA office complex' and says RAGHSA is listed on BYMA. That RAGHSA owns rather than merely developed it rests on 'for lease' (unlike its 'Sold' buildings, such as Edificio Plaza San Martín); no title was bought. |
Public company | —A |
| Libertador Hotel (former Sheraton Libertador) Downtown City of Buenos Aires (street address not stated in the filing) 193 rooms + 7 suites |
Hotel | Hoteles Argentinos S.A.U. (100% IRSA Inversiones y Representaciones S.A.) 100% IRSA's 20-F: 'In March 1998 we acquired 100% of the Sheraton Libertador Hotel from Citicorp Equity Investment for an aggregate purchase price of USD 23 million'; after reacquiring the 20% sold to Sheraton, IRSA reached 100% of Hoteles Argentinos S.A.U. and now operates it as 'Libertador'. IRSA also holds 76.3% of the Intercontinental Buenos Aires (313 rooms, Monserrat), with InterContinental Hotels Corporation at 23.66%. |
Public company | USD 23M 1998-03 IRSA bought 100% from Citicorp Equity Investment; sold 20% to Hoteles Sheraton de Argentina for USD 4.7M (Mar 1999) and bought it back in FY2019. A |
| Puerto Retiro — 'Planta 1' (former Tandanor shipyard land) Retiro port area, next to Puerto Madero, City of Buenos Aires 8.3 ha |
Land | Contested: Puerto Retiro S.A. (50% IRSA); Supreme Court ordered restitution to Tandanor (Nov 2024) IRSA 50% of Puerto Retiro S.A. (via Inversora Bolívar) IRSA's 20-F: Puerto Retiro S.A. holds an 8.3 ha plot zoned U.P. (port use only), bought as 'Planta 1' from Tandanor after the 1991 privatisation that the Ministry of Defense later litigated. In Nov 2024 the Corte Suprema (CSJN) upheld the Ministry's and Tandanor's appeals, confirmed the confiscation (decomiso) of Planta 1 and ordered it returned to Tandanor rather than the State; a criminal court closed the leased premises. Puerto Retiro impaired 100% of the property's book value. A distressed, contested title. |

The core land
The most valuable ground in the city, and what the public record says about it.
The most valuable ground is the corporate strip from Plaza San Martín and Catalinas to Puerto Madero. The City publishes no assessed values (AGIP's valuations are not an open file), so what the public record gives is prices: rents and floor sales in listed companies' filings, the City's concession canons, and the State's auction bases.
Highest premium-office rents by submarketPlaza San Martín USD 26.30/m²/month; Puerto Madero 23.90; Catalinas 23.00
Colliers figures for Q2 2025, quoted in IRSA's 20-F (filed 24 Oct 2025): A+ average USD 23.43, A USD 19.94; premium vacancy 14.46%.

Who owns the town
At this scale the significant owner is rarely a trust or a fund: it is one or two local holding companies, a family in its second or third generation, and often the land around the town rather than the buildings in it.
Public bodies hold most of Buenos Aires' landmark ground. The Nation owns the seat of government, the railway land (administered by ADIF; surplus land passes to the AABE, which auctions it), the airport (under concession) and, through the Ministry of Defense's shipyard company Tandanor, a contested 8.3 ha port plot. The City holds the Costanera riverfront as public domain and lets it by concession, and has auctioned smaller buildings to IRSA. Puerto Madero was urbanised by a Nation–City company that sold the plots on. No register-based ranking of landholders exists; the figures are each body's own.
| Name | Type | Holding as the source states it |
|---|---|---|
| Gobierno de la Ciudad Autónoma de Buenos Aires (GCBA) Res. Conj. 43/MJGGC/25 lets Costa Salguero, City public-domain land on the Costanera Norte, on a 10-year concession. The City also auctions property it no longer needs: IRSA's 20-F records buying from the GCBA by public auction the Beruti / Coronel Díaz corner opposite Alto Palermo (Feb 2022, 2,387 m² plot) and Paseo Colón 245 with 12 parking spaces at Paseo Colón 275 (awarded 28 Dec 2022, c. 13,700 m², 13 storeys). BA Data's 'Edificios Públicos' dataset (CC BY 2.5 AR) lists the buildings used as City offices, owned or rented, without saying which. |

| Estado Nacional — Agencia de Administración de Bienes del Estado (AABE) The AABE administers national State real estate, including railway land released from rail use (Law 26.352, art. 3, as amended by Decree 1382/2012), and sells it by public auction through SUBAST.AR. Its listing for Subasta Pública 392-0032-SPU26 offers a five-level building at Juncal 847/51 near Plaza San Martín at a base of USD 1,592,142; status 'Finalizado', with no result stated. The national holdings in the City are not published as a total. |

| Administración de Infraestructuras Ferroviarias (ADIF) / Trenes Argentinos Law 26.352 gives ADIF 'la administración de la infraestructura ferroviaria' and the goods needed for it; the operator administers the property ADIF assigns it; the assets are those 'cuya titularidad ostenta el Estado Nacional'. No area or count of railway land in the City is published in the sources opened. |

| Ministerio de Defensa — Tandanor Per IRSA's 20-F, the Ministry of Defense and Tandanor won at the Supreme Court in Nov 2024: the confiscation of Planta 1 was confirmed and its restitution to Tandanor ordered, against Puerto Retiro S.A. (50% IRSA). No other Defense holdings in the City were established from a source opened. |

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.
Argentina publishes no builder league table, and new flats in the City are mostly built by private developers who sell off-plan unit by unit, often trading land for finished square metres (canje). The figures below come from each builder's own filing or page. The City's housing institute builds for the informal settlements it is integrating; RAGHSA's luxury towers are sold out. TGLT's site forbids any use of its content, and Consultatio's robots.txt disallows all agents, so neither is counted.
| Name | Type | Units or area as the source states |

Commercial landlords
The commercial side, counted separately from housing: who holds the office, retail and industrial floor area.
Two listed companies dominate the City's investment-grade commercial stock. IRSA owns six of the City's shopping centres outright or in majority and a small premium-office portfolio, which it has been selling floor by floor; its own 20-F names RAGHSA S.A. as the other leading premium-office player. Cencosud, IRSA's main mall rival, owns Unicenter in Greater Buenos Aires. Many towers in Catalinas and Puerto Madero are commercial condominiums whose floor owners are not published.

Looked for and not found
Claims this page would have made if a source could be opened. They are left out rather than guessed.
- Corporación Antiguo Puerto Madero's remaining land and its 50/50 Nation–City shareholding as it stands today — from Wikipedia only; cpm.ar was outside its robots visit window.
- Costa Salguero: the prompt's 'City sale' is not borne out — the 2020 sale law was stopped by a court and the Dec 2025 resolution still calls the land City public domain and lets it on concession. The current state of the 2020 case was not read from a court record.
- Owners of the other Catalinas Norte towers (e.g. Torre Catalinas Plaza, the Consultatio tower) and of the Puerto Madero office floors — commercial condominiums whose unit holders are named only in paid RPI Informes N° 1.
- Buyers of the 261 Della Paolera floors IRSA sold in 2023–2025 (about 14,276 m²) are not named in the 20-F.
- Catholic Archdiocese of Buenos Aires — no holdings figure; arzbaires.org.ar returned only a maintenance page.
- Ministerio de Defensa's other City holdings (e.g. Edificio Libertador, regimental land in Palermo) — no source opened states them.
- UBA's total holdings (Ciudad Universitaria, Hospital de Clínicas, faculties) — not quantified by any source opened.
- Largest private residential developers by units (Consultatio, TGLT and others) — no filing or freely usable page gives counts; TGLT's terms forbid use of its content and Consultatio's robots.txt disallows all agents.
- Who must show 'interés legítimo' to request RPI reports under Law 17.801 — the RPI's own web service is offered to 'público en general'; the statute itself was not opened.
- Ownership of the Aeroparque land is inferred from the concession structure; no deed or AABE record was opened.
