This checklist explains in plain, practical terms when landlords must justify modernizations, which deadlines apply, how costs may be allocated and what rights you have as a tenant.

The guidance refers to applicable German law and names key statutes and local courts as points of contact. This helps you meet deadlines, protect yourself from high costs and respond professionally to the notice. Read the steps below and act in time.

What a modernization notice means

A modernization notice informs about planned construction measures and possible cost allocations under the BGB. Check whether the landlord states the purpose, scope and start and whether a clear cost breakdown is provided.^[1]

Checklist: Steps for tenants

• Check deadlines (deadline): Note announcement and start dates and verify legal time limits.
• Review the notice in writing (form): Pay attention to scope, duration, start and a clear cost breakdown.
• Check costs and allocation (payment): Clarify which costs are allocated and in what amount.
• Collect evidence (evidence): Take photos and secure correspondence, invoices and statements.
• Consider legal advice (court): Decide whether an objection or a claim at the local court is necessary.

Forms and templates

There is no uniform federal form requirement for objections to modernization; often a formal letter is sufficient. For court proceedings use civil claim forms and the justice guidance; legal bases are found in the BGB and the ZPO.^[1][2]

Example: An objection letter can read: "I hereby object to the announced modernization dated [date] because the cost allocation is not sufficiently justified." Send the letter by registered mail or verifiable email and document the dispatch.

FAQ

How much notice must the landlord give?

The landlord must announce the planned modernization in good time; specific deadlines depend on the scope and are governed by BGB provisions.^[1]

Only certain modernization costs may be passed on; check the cost breakdown carefully and request supporting documents.

When is a rent reduction possible?

A rent reduction may be possible if the usability of the flat is impaired; document defects and consider legal action.
