Modernization Notice: Tenant Rights in Germany
As a tenant in Germany, you should carefully check modernization notices. Landlords must clearly state scope, expected duration, start of work and anticipated costs in writing so you can meet deadlines and know your rights such as objection or rent reduction. This guide explains in plain language which information the notice must contain, how to respond formally, which deadlines apply and when a cost surcharge is possible. You will also find sample wordings, information on official forms and a step-by-step plan for handling a modernization notice in Germany. It also includes tips on collecting evidence, which deadlines the BGB sets and which courts you can contact. If unsure, we show which official forms and template letters help.
What must a modernization notice contain?
The notice must clearly state the scope of the measures, the planned start and expected duration, as well as the expected costs and any possible cost allocation. Check whether the text specifies the type and purpose of the works and whether dates are named precisely. Read the notice carefully and note the date and method of receipt.
Deadlines and response options
There are deadlines for objections and information obligations of the landlord. Notices often must include a period for preparation and possibly for comment. Check whether deadlines are stated and respond in writing if you have objections.
- Formal notification: check date, signature and delivery method.
- Check planned start and duration of the works and note deadlines.
- Review expected costs and notes on cost allocation.
- Information on impairment of usability (e.g. loss of heating or water).
Cost allocation and §559 BGB
Under the BGB, the landlord can under certain conditions allocate part of the modernization costs to tenants; the rules are set out in §559 BGB.[1] Pay attention to correct calculation and to the landlord's duty to make costs transparent. General tenancy obligations and rights are stated in §§ 535–580a BGB.[2]
