An amendment to the Geodetic and Cartographic Law has abolished fees for access to data from the Real Estate Price Register. The change, which came into effect on February 13, allows citizens to check actual transaction amounts free of charge directly in county databases. While the reform aims to increase market transparency, the Personal Data Protection Office has raised concerns about the privacy of property buyers, sparking a debate about the limits of transparency in the real estate development sector.

Removal of Financial Barriers

As of February 13, 2026, data from the Real Estate Price Register is provided free of charge to all citizens, ending the era of paid extracts.

Increased Market Transparency

Thanks to the new regulations, anyone can check transaction prices in their area, facilitating property valuation without costly expert assistance.

The Personal Data Protection Office warns that full transparency of registers could threaten citizens' privacy by easily linking prices to specific individuals.

A revolution in access to real estate market data has become a reality with the entry into force of the amendment to the Geodetic and Cartographic Law. As of February 13, 2026, citizens can use the resources of the Real Estate Price Register (RCN) free of charge. Previously, obtaining an extract from the register required paying a stamp duty, which effectively limited access to information for the average buyer. Now, this data is becoming available in digital mapping services, such as the Warsaw Map Service, where transactions can be analyzed on an interactive map. The initiative to make this data free was led by Prof. Waldemar Izdebski, the former Chief National Geodesist, who had long advocated for removing financial barriers to access to public information. However, these changes are not without controversy, as noted by experts cited by Rzeczpospolita. A key actor in the dispute over the shape of the new regulations has been the Personal Data Protection Office (UODO). This body expressed concern that overly broad access to detailed transaction data—combined with information from land and mortgage registers—could lead to the de-anonymization of buyers and violate their privacy. In response to these concerns, legislators had to balance price transparency with the protection of personal rights, which influenced the final shape of the regulations on the Developer Guarantee Fund.

In practice, the new tool allows for precise tracking of the market value of properties in the immediate vicinity. A media example was the situation of Jarosław Kaczyński, whose neighbors in Żoliborz are conducting renovations, which incidentally made the public aware that, thanks to the RCN, one can check the exact amounts for which parts of nearby duplexes are purchased. Experts note that while municipal systems can be difficult to use, the digitization process and complete removal of fees is a milestone. Data enters the system within 30 days of signing a notarial deed, making the database relatively up-to-date and a powerful negotiation tool for those planning to buy or sell real estate.
