Rent & increases (reference rent, categories, form) 2 min read · published September 10, 2025

Many tenants in Austria face questions when the landlord plans energy upgrades such as facade insulation or replacing windows. These measures can improve living quality and reduce heating costs in the long run, but they also affect tenant rights such as access to the apartment, rent changes, or possible disruptions during the work. In this article we explain in clear language when landlords may carry out such work, which notification and consent rules apply, what costs you might face, and which steps tenants can take to protect their interests. We give practical tips on documenting, meeting deadlines and avoiding disputes with the landlord. If in doubt, we recommend timely advice and careful documentation.

When may landlords carry out insulation and window replacement?

Landlords may carry out energy measures in many cases if they serve maintenance or modernization. Key are legal bases such as the Mietrechtsgesetz (MRG) and contractual agreements with the tenant; changes that allow rent adjustment are strictly regulated.[1] Before starting, landlords usually must announce in good time, specify the scope and duration of the work and point out possible disruptions.

In many cases tenant rights remain in place even during modernizations.

What rights do tenants have?

  • Access only after notice and only to a reasonable extent.
  • Rent adjustments are only possible on a legal basis or by express agreement.
  • Notification deadlines and formal requirements must be observed.
  • Right to functioning heating and sealed windows remains.
Document appointments, defects and communication in writing.
