Important Changes for Landlords from 2026

Legal Updates

Key Takeaways

  • Heating costs must be calculated more transparently
  • CO₂ costs will be shared between tenant and landlord
  • New requirements for energy-efficient renovations
  • More digital obligations (e.g., real-time consumption data)

Heating Cost Regulation 2026

From 2026 onwards: heating cost statements must consider consumption data in real-time. Landlords must install remotely readable measuring devices for this purpose (§ 6 Heating Cost Ordinance).

📌 Legal Precedent Example

Munich Regional Court I, 31 S 23119/15: Faulty heating cost statements lead to reduction obligations.

💡 Practical Tip

Check now whether your meters comply with EU requirements. Replacement obligation until the end of 2026!

CO₂ Cost Distribution

CO₂ costs will be distributed in a graduated manner according to building energy efficiency in the future. An unrenovated house means: landlords pay more. Modernized apartment: tenant takes on a larger share.

Checklist: Preparing for CO₂ Distribution

  • Check energy certificate
  • Determine renovation needs
  • Adjust utility cost items
  • Prepare communication to tenants

Energy-Efficient Renovations

New funding programs are intended to motivate landlords to modernize buildings. At the same time, requirements are increasing – those who don't renovate bear higher CO₂ costs.

Digitalization Obligations

In addition to heating cost statements, consumption information for water and electricity will also become more transparent. Landlords must provide this data, otherwise they face additional payments or fines.

Conclusion

From 2026, it will become more digital, transparent, and expensive for landlords if they don't modernize. Those who exchange meters early, factor in CO₂ costs, and use funding are clearly at an advantage.
