Portal DOM: New system for housing price information

The act creates Portal DOM, a public database of transaction prices for apartments and houses. Buyers will be able to check average prices in a given area, making negotiations easier. Developers and some entrepreneurs will have to submit detailed contract data, and providing false information can result in a fine or even up to 2 years in prison.
Key points
A public Portal DOM will be created with information on average transaction prices of apartments and houses, accessible to every citizen.
Developers and some sellers will have to submit data on concluded contracts (price, area, number of rooms, etc.) to Portal DOM within 7 days.
Knowingly providing false data to Portal DOM is punishable by a fine, restriction of liberty, or imprisonment for up to 2 years.
Portal DOM will also serve the government and public institutions for housing market analysis and housing policy.
The act enters into force 16 months after publication, but some provisions (e.g., regarding Portal financing) will take effect earlier.
