Tenant: Hardship Objection & Cost Records in Germany

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

Many tenants in Germany face the challenge of plausibly documenting modernization costs or monument conservation measures and preparing a hardship objection without legal assistance. This guide explains in plain language which documents are relevant, how to systematically record costs in monument protection, and which deadlines and courts are important for rent disputes. I show step by step how to collect evidence, create a clear cost breakdown and draft a formal letter to the landlord. The aim is to give you, as a tenant, practical tools to check your rights and present objectively justified objections. I name relevant sections such as §535 BGB and refer to the competent local court as well as practical wording templates and checklist items for your files.

What is a hardship objection?

A hardship objection means that a cost burden would be unreasonable for you as a tenant. In tenancy law this can mean that a announced modernization or cost allocation is reviewed and possibly reduced or rejected. Relevant legal bases can be found in the BGB and procedurally in the ZPO.[1][2]

In most cases the reasonableness of the costs determines the success of a hardship objection.

Documenting costs in monument protection

  • Take photos and organize receipts (evidence, receipts) chronologically with dates.
  • Copy invoices, quotes and receipts (receipt, invoice); keep originals safe.
  • Create a detailed cost breakdown listing materials, labor and surcharges (amount, payment) separately.
  • Collect permits, decisions and correspondence (form, application) and note dates.
Detailed documentation increases the chances that courts or landlords will take the hardship objection seriously.

How to structure a hardship objection

Immediate steps

  • Collect evidence immediately after receipt (evidence) and note date and source.
  • Observe deadlines: respond within set timeframes (within, deadline) and keep copies ready.
Respond within set deadlines or you may lose claims.

Cost breakdown

Create a tabular overview with items, amounts and sources. Mark which costs are due to monument conservation and which relate to general modernization.

Formal letter to the landlord

  • Draft a clear hardship objection with date, demands and references to evidence (form, notice).
  • Request a detailed cost statement from the landlord and set a reasonable deadline (call, contact).
  • If no agreement is possible, consider the path to the local court (court) and collect all documents for a possible suit.[3]
Keep copies of all letters and proof of delivery.
