New Hungarian Brownfield Directory to Support Real Estate Development

By Kinga Hetenyi, Partner, Schoenherr

BarKA is Hungary’s first comprehensive national directory of brownfield sites, recently published by the Ministry of Construction and Transportation to facilitate sustainable urban development and real estate investment.

Key features

The newly accessible online database catalogues nearly 12,000 hectares of brownfield areas across Hungary, with approximately 2,500 hectares located in Budapest alone. The directory is publicly available at oeny.hu/oeny/barka/, providing transparency and accessibility to developers, investors and local authorities.

Implications for real estate developers and investors

The launch of BarKA raises several important considerations for stakeholders in the Hungarian real estate market:

  • Authentic public register status: BarKA is established as an official public register under Hungarian law, ensuring the reliability and authenticity of the data contained therein.
  • Enhanced due diligence opportunities: The directory provides a centralised resource for identifying potential development sites, enabling more efficient preliminary assessments and site-selection processes.
  • Regulatory compliance: Developers should be aware that brownfield sites typically require environmental assessments and may be subject to specific remediation obligations under Hungarian environmental legislation before development can proceed.
  • Investment planning: The catalogue’s comprehensive scope offers investors a clearer overview of available brownfield opportunities, potentially accelerating project timelines by streamlining the site identification phase.

The introduction of BarKA represents a positive development in Hungary’s efforts to promote sustainable land use and urban regeneration, while enhancing transparency in the real estate market.
