Energy Certificate and Rental Documents in Austria

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

As a tenant in Austria it is important to know which documents landlords or authorities may request regarding the energy certificate and rental matters. In this article I explain in plain language which documents you should have ready when moving in, facing a rent increase or proving the energy certificate, how to observe deadlines and formal requirements and which proofs help in repairs or payment disputes. I provide practical checklists for organizing receipts, which clauses in the lease matter and when court action may become necessary. The information is based on Austrian regulations and shows how you can protect your rights as a tenant. If unsure, contact the tenants' association or official bodies in good time.

Which documents belong together?

  • Lease agreement (complete copy)
  • Energy certificate or consumption information (if available)
  • Payment proofs (rent, deposits)
  • Handover protocol (meter readings, damages)
  • Written correspondence with the landlord (reminders, agreements)
  • Receipts for repairs and reports of defects
  • Official notices or court mail
Keep copies of all documents for at least five years.

Formal requirements, deadlines and rent increases

Certain declarations must be made in writing in Austria and deadlines must be observed: for rent increases there are formal requirements and often the need to provide evidence by comparison apartments or category rent; notices and warnings usually include deadlines that are decisive[2]. Check every delivery for stated deadlines and ask for written clarification if unclear.

Respond to notices within the stated deadline.

Energy certificate: important notes

The energy certificate provides information about the energy consumption of a building or apartment; as a tenant you can request it to estimate heating cost comparatives[1]. It is not always the tenant's duty to obtain the certificate; usually the landlord or property manager provides it on request. Keep written transmissions and all invoices related to heating cost allocations.

How-To

  1. Collect all relevant documents in one place, including lease, energy certificate and payment receipts.
  2. Check deadlines in letters and notes so you can react in time.
  3. Send important declarations by registered mail or request a written confirmation.
  4. Contact the tenants' association or advisory services early if unsure.
  5. If necessary, prepare documents for court and use JustizOnline forms for filings[3].
