Until now the Polish real estate market in terms of transparency largely resembled cryptocurrency exchanges, and unfortunately from their early days.
The end of digital medieval times and developer insurgency
Although the 2025 regulations imposed a clear duty on developer companies to provide price and area data on the government portal dane.gov.pl, in practice there was total self‑service.
The Ministry of Digital Affairs did prepare an advanced, structured data format for machine reading, but its use was so far only a loose recommendation. Result? Some large market players ostentatiously ignored these guidelines, serving data in a chaotic way that effectively prevented automatic aggregation and analysis.
For developers this informational noise was a very convenient smoke screen. The average client had to sift through a jungle of incomparable offers, while the industry could freely craft a marketing narrative of eternal growth and alleged lack of alternatives.
The amendment prepared by MPs from Polish 2050 aims to end this once and for all, introducing rigid rules of the game. The Senate has just adopted this key law with editorial and clarifying amendments.
The voting result of the upper house leaves no doubt about the politicians’ intentions – 62 “for”, 30 abstained, and no one voted against it.
Now the draft will again go to the Sejm, from where the path to the president’s signature is straightforward.

Algorithms enter the real estate market with a thunderous force
Introducing a uniform format, which the Ministry of Digital Affairs will define through an official regulation, is literally a technological leap forward.
The era of manually rewriting rates from price lists, single tables, or unreadable PDF files ends forever.
A structured data format will open doors for advanced analytical tools, next‑generation price comparators, and sophisticated AI algorithms. Creators of innovative systems and investment platforms will be able to process Polish housing market data in real time.
Transparency will help consumers make rational purchasing decisions and significantly reduce speculative price anomalies.
The legislator was fully aware that without hard and ruthless sanctions, new rules would become just dead law written on paper. That’s why the amendment includes a powerful financial scare that will hit anyone who tries to game the system.
Failure to use the required, uniform format on the platform dane.gov.pl will no longer be treated as an innocent technical mistake or minor oversight.
The Office of Competition and Consumer Protection will have full authority to impose a financial penalty of up to 10% of the annual turnover of the entire enterprise.
For large developer projects, where revenues are in tens or hundreds of millions of PLN, such a sanction means financial knockout and bankruptcy risk.
It is worth noting that the Senate’s proposed amendments are clarifying, so the whole machine will start very quickly.
New rules will come into force three months after their announcement, meaning developers have little time to transform their databases.
Those who fail to adapt to the new rules will quickly face gigantic penalties from UOKiK.
