On 21 May 2025, the Sejm adopted an amendment to the Development Act, which aims to increase transparency in the real estate market and better protect buyers of dwellings and houses. The new regulations introduce, among others, an obligation of open publication of the prices of premises on developers’ websites, which should prevent unfair practices and facilitate comparing of offers. The amendment introduces new obligations for developers, in particular the requirement to disclose real estate prices. This will translate into new administrative and organisational challenges for companies operating in the development industry. Foreign entities planning to enter the Polish market will have to adapt their current practice to Polish regulations, which may have a direct impact on their existing business strategies.
