Amendment to the Developer Act: what's changing for buyers and developers?
On 5 June 2025, the President of the Republic of Poland, Andrzej Duda, signed an amendment to the regulations concerning the protection of the rights of individuals purchasing flats and single-family houses. The changes introduced to the Act of 20 May 2021 aim to increase market transparency and strengthen the position of buyers.
New information obligations for developers
Under the amendment, companies offering properties for sale – both developers and other businesses – must provide complete, reliable and up-to-date data on the units offered. Particular emphasis has been placed on price information – customers should know not only the current value, but also the history of price changes.
The most important changes in the regulations:
- Improving the process of taking over flats and houses New regulations are intended to make acceptances more orderly and transparent.
- Greater price transparency – obligation to publish actual prices and update them.
- Extension of the information catalogue that must be made available to the buyer, including details of the investment, the standard of workmanship and the schedule.
- Access to price change history – customers will be able to check how property prices have changed over time.
- Stronger protection of buyer rights, including ensuring they have the right to the best available price.
- Reporting obligation for data to the Ministry of Development and Technology, which is intended to improve market monitoring.
- Changes in the functioning of the Developer Guarantee Fund – the aim is to protect client funds more effectively.
- Extension of the scope of contracts covered by the Act, which is to increase security also for less standard transactions.
- New regulations concerning the right to refuse to accept a property and to withdraw from a contract – particularly important in cases of significant defects being detected.
