Poland's Property Price Register after the changes: how to read transaction data

On 13 February 2026, an amendment to the Geodetic and Cartographic Law came into force, abolishing fees for access to data from the Property Price Register (Rejestr Cen Nieruchomości, RCN). Information on transaction prices from notarial deeds, previously available for a fee and on request, is now free of charge. It is a step towards market transparency, following the publication of apartment asking prices in mid-2025. RCN data is, however, easy to misread – especially for land intended for multifamily housing.

What has changed

The amendment to the Geodetic and Cartographic Law was published in the Journal of Laws on 12 November 2025 (item 1542) and came into force three months later. The most important change for market participants: data from the Property Price Register is provided free of charge.

The RCN is kept by district heads (starosta) and by the mayors of cities with district rights – in Kraków, by the Mayor of the City. The register is fed with data from notarial deeds, so it covers prices actually paid rather than asking prices.

What the RCN contains

The register includes, among other things:

• the date of the transaction and the reference of the notarial deed,
• the transaction price,
• the property's identification – cadastral plots, their area and location,
• the type of property and the type of right (ownership, perpetual usufruct),
• for units – the floor area and basic characteristics.

Pitfalls when analysing land prices

Plot prices in the RCN are a valuable source of information, but for land intended for multifamily housing they need careful interpretation:

1. No information on buildable capacity. The register gives the price and the area of the plot, but not how much PUM (usable floor area of apartments) can be built on it. Two transactions at PLN 1,000 per square metre of land may mean completely different prices per square metre of PUM.
2. No information on planning status. The RCN does not show whether the plot had a local zoning plan, a zoning decision (WZ) or neither. For land value, this is crucial information.
3. Multi-plot transactions. When one price covers several plots, it is easy to attribute the price wrongly to a single plot or to confuse the area.
4. Atypical transactions. Disposals of shares, sales to a co-owner, transactions between related parties, exchanges or contributions in kind may involve prices that differ from market levels.
5. VAT. Prices of building land may be shown net or gross of VAT – this needs to be checked when comparing transactions.
6. The structure of the agreement. The price in a notarial deed does not always reflect the full value of the transaction – e.g. when part of the consideration depends on obtaining a building permit, is deferred, or the buyer assumes additional obligations.
7. Delays and completeness. Data reaches the register with a delay, and completeness and the way data is made available vary from district to district.

How to use the RCN when selling a plot

The RCN is best treated as one of several sources:

Only by combining these data can the value of land be assessed realistically. In advisory practice, it is particularly important to convert transaction prices into zlotys per square metre of PUM, taking into account the planning status of the plots concerned.
