    GEG obligations for landlords

    The Building Energy Act () defines minimum requirements for the energy condition of existing buildings. Retrofit obligations apply on ownership change or major renovations. The modernisation levy allows landlords to pass on up to 8% of costs to annual rent, capped at EUR 2-3/m².
    GEG 2024: Heating replacement obligation for new builds from 01.01.2024, existing buildings dependent on municipal heat planning (by 2028 at latest).
