Santiago Launches Digital Registry to Combat Housing Fraud, Trails Rivals
As Chile's housing crisis deepens, Santiago is betting on a digital property registry overhaul to eliminate duplicate building permits and fraudulent land titles, but peer cities in Latin America are already further ahead.
How we reported this
Santiago's Conservador de Bienes Raíces, the notarial registry that underpins every property transaction in the city, is sitting on a backlog of roughly 340,000 digitisation requests, according to figures presented to the Ministerio de Vivienda y Urbanismo, known as MINVU, earlier this year. At the heart of the problem: thousands of properties listed twice, under different folio numbers, creating legal chaos that has blocked affordable housing construction in communes including Pudahuel, Cerro Navia and La Pintana.
The issue matters now because the Boric administration has staked a significant share of its political credibility on delivering 260,000 new housing units before 2026 ends. Duplicate image entries, scanned title documents that appear more than once in the national cadastre, sometimes with conflicting ownership data, are quietly strangling that pipeline. Developers cannot break ground when a plot of land carries two contradictory legal owners. Banks will not finance construction against a title flagged by the registry system as a potential duplicate.
What Santiago Is Actually Doing
MINVU launched a dedicated deduplication pilot in March 2025 under its Plan de Emergencia Habitacional. The program targets 12 comunas in Gran Santiago, using optical character recognition software to cross-reference scanned deeds against GPS coordinates held by the Servicio de Impuestos Internos. The pilot is operating out of a processing centre on Avenida Libertador Bernardo O'Higgins 1449, in the Barrio Cívico, where a team of around 60 contracted data analysts works alongside registry staff.
The Cámara Chilena de la Construcción, the national construction industry chamber, flagged the duplicate title problem in a report it published in November 2024. The chamber identified at least 11,200 urban plots across the Región Metropolitana carrying duplicate cadastral entries, with the highest concentrations in Maipú and Quilicura, two communes under heavy immigration-driven housing pressure. Neither MINVU nor the Conservador de Bienes Raíces has publicly disputed those figures.
How Santiago Compares to Bogotá and São Paulo
Bogotá moved earlier. Colombia's capital completed a full digitisation of its Registro de Instrumentos Públicos in 2022, a process that took four years and required a dedicated budget line of approximately COP 38 billion, roughly USD 9 million at the exchange rate of the time. The city's Unidad Administrativa Especial de Catastro Distrital now runs automated duplicate-detection algorithms that flag inconsistencies within 48 hours of a new filing. Santiago has no equivalent real-time check yet.
São Paulo is a more complicated comparison. Brazil's federal property registry system, the SREI, began mandatory electronic integration for all notary offices only in 2021, and São Paulo's 89 cartórios are still in uneven compliance. By that measure, Santiago's centralised Conservador structure is an administrative advantage, the city has one registry, not dozens of competing offices. The problem is not fragmentation. It is the pace of digitisation.
In practical terms, a developer trying to build social housing in Lo Espejo today waits an average of 118 days to clear a flagged duplicate entry, according to figures the Cámara Chilena de la Construcción cited in its November 2024 report. In Bogotá's system, the equivalent administrative clearance runs closer to 30 days. That gap is costing Santiago projects.
MINVU has said it expects to clear the backlog in the 12 pilot comunas by the third quarter of 2026. If the timeline holds, the program will expand to the remaining 40 comunas of the Región Metropolitana by mid-2027. Registry advocates and housing groups are watching closely: the constitutional process that reshaped property rights debates between 2021 and 2023 left unresolved questions about communal land titles in peripheral districts like Lampa and Colina, where duplicate entries are also common.
For residents dealing with the problem directly, MINVU operates a consultation line, Fono MINVU 600 901 1900, where property owners can flag suspected duplicate cadastral entries and request a manual review. The Conservador de Bienes Raíces also accepts written petitions at its main office on Morandé 440, near Plaza de Armas. Processing times for manual petitions currently run between 60 and 90 days. That is not fast enough for a housing emergency, but it is a start.
