What tenants should pay attention to

Landlords have duties for maintenance and disclosure; many tenant rights derive from the Civil Code, in particular regarding modernization, rent reduction and operating or heating cost accounting.[1] Before consenting to a PV system or tenant power contracts, tenants should check which costs may actually be allocated and whether social housing regulations provide special protections.

  • Cost allocation: Clarify in writing which modernization costs the landlord will pass on to rent.
  • Deadlines: Request time to review the offer and to obtain advice.
  • Documentation: Photograph meter readings, contracts and payment receipts.
  • Access and installation: Agree on clear times and inform about possible disruptions.
Keep all bills and contracts organized and stored in chronological order.

Rights, duties and forms

Tenants should know the relevant legal bases, for example who bears modernization costs and when rent reduction is possible.[1] In case of disputes the local district court is competent; for legal questions and appeals the route can lead to the regional court or the Federal Court of Justice.[2]

  • Template termination/letter: Use a clear, dated letter to record consent or objection; attach all relevant evidence.
  • Complaint forms (CPC): For eviction claims or accounting disputes an appropriate complaint form may be required; contact the competent district court.
  • Social housing/WBS inquiries: Ask the responsible authority whether special rules apply to tenant power.
Respond within set deadlines to avoid losing rights.

How-To

  1. Check the lease: Read clauses on modernizations, cost allocation and duty to tolerate carefully.
  2. Collect information: Request the offer, cost breakdown and technical data in writing.
  3. Assess costs: Have it checked which investments are allocable and whether subsidies or social rules apply.
  4. Negotiate in writing: Formulate your consent or concerns in writing and propose transparent agreements.
  5. In disputes, act: Consider mediation or filing a claim at the district court; document all steps.

FAQ

Can the landlord install a PV system on my rented property without consent?
Generally, landlords often need consent for interventions in the rented property or must justify the measure as modernization under the Civil Code; check your contractual rights and seek advice.[1]
Who pays for installation and maintenance?
The allocation of modernization costs is regulated by law; not all costs may automatically be passed on to tenants and social housing rules can provide added protection.[1]
Where do I turn in case of a dispute with the landlord?
Usually the local district court is the first point of contact for tenancy disputes; for larger legal questions, regional courts or the Federal Court of Justice may be relevant.[2]
