Tenants & Monument Protection: Retrofit in Germany

Modernization & Cost Allocation 2 min read · published September 07, 2025

As a tenant in Germany, an energy retrofit on a listed building can raise questions about rights, obligations and possible rent increases. This article explains in plain language which legal rules apply, which notification deadlines and forms you must observe, and how monument protection requirements can change renovations. I describe practical steps to check official notices, document defects, communicate with the landlord, and take action in court or at the local court if necessary. The guidance helps tenants follow deadlines, draft objections, and contact authorities to prepare decisions about modernization in Germany in a comprehensible and legally sound way.

Check energy retrofit in monument protection

If an energy retrofit is planned for your rental property, both tenancy law under the BGB and special monument protection regulations apply. Under §559 BGB the landlord can pass some modernization costs on to the rent[1], but monument protection may impose conditions or funding rules that change deadlines and obligations. Check the modernization notice for scope, deadlines and information about structural interventions, and ask the landlord for detailed written documents if anything is unclear.

In most regions, tenants are entitled to basic habitability standards.

What tenants need to know

  • Rights in modernization: when costs may be allocated and how rent increases can be calculated.
  • Notification deadlines and dates: which deadlines apply and how much notice is required before work begins.
  • Consent requirements and monument protection conditions: which works need permits and when authorities must be involved.
  • Documentation: photos, defect reports and a complete dated record of communications.
Detailed documentation increases your chances in disputes.

Concrete action steps

  1. Check the modernization notice in writing and note all deadlines.[2]
  2. Document the current condition: photos, heating costs, defects and communications.
  3. Contact the monument office and obtain written confirmation of applicable requirements.
  4. If necessary: inform the local court or seek legal measures; review rent reduction options and deadlines.[3]

Frequently Asked Questions

Can the landlord carry out an energy retrofit in a listed building without my consent?
In principle the landlord can carry out modernizations, but tenant rights, notification deadlines and any consent obligations must be observed; substantial interventions may require tenant involvement.
Can the rent be increased after a modernization?
Yes, under conditions of §559 BGB a rent increase for modernization may apply, but monument protection conditions and funding rules can limit this. [1]
Which forms or templates should I use?
Use official forms for objections or termination and document correspondence clearly with dates.

How-To

  1. Read the modernization notice completely and mark deadlines and scope.
  2. Create a complete record (photos, meter readings, correspondence).
  3. Communicate in writing with the landlord and request missing documents.
  4. If no agreement is possible, contact the local court or a legal advice service.
