Law 5197/2025 introduces targeted clarifications to the New Building Regulation (Law 4067/2012), restricting the application of incentives and bonuses to designated incentive zones within Local or Special Urban Plans. It also regulates how building permits issued up to 11 December 2024 are treated, depending on construction status, and establishes an Environmental Equivalent mechanism allowing certain projects to proceed under specific conditions. These measures aim to ensure clarity, legal certainty, and promote environmentally responsible urban development.
