Accessible Bathroom in Old Buildings for Tenants in Germany

As a tenant in Germany you need clear information when planning an accessible bathroom in an old building. Old pipes, missing landlord consent and wrong assessments of structural issues or funding options often cause delays, extra costs or legal problems. This guide explains in plain language which permits are necessary, which typical mistakes can be avoided, how to check costs and funding, and which rights and deadlines apply to tenants. I show practical steps for documentation, talking with the landlord and securing written agreements. This helps you as a tenant keep control of schedule, accessibility and your rights in Germany. Use the checklist below.

Planning and Consent

Before starting alterations you usually need the landlord's consent. Tenancy law in the BGB governs landlord and tenant duties, especially regarding structural changes and repairs ^[1]. Request written permission specifying cost allocation, deadlines and restoration obligations. Without a written agreement you risk later claims or restoration demands at move-out.

Avoiding Technical and Structural Errors

Typical planning mistakes come from inaccurate cost estimates, lack of structural checks or unsuitable materials. Pay attention to the following points:

• Unclear structural assessment or load-bearing capacity, especially if removing walls.
• Undetected routing of water and wastewater pipes that can cause moisture damage later.
• Incomplete cost estimate, missing quotes or overlooked ancillary costs like temporary power or disposal.
• Missing written agreements on deadlines, acceptance and warranties.
• Insufficient documentation of defects or prior condition before renovation.

Permits, Deadlines and Rights

Some measures require a building permit or notification to the building authority; this varies by state. Clarify whether changes to the building structure require approval and whether subsidies or grants are available. Agree clear deadlines with the landlord, because delayed work can lead to rent reductions or claims for damages. Rental disputes are usually handled by the local court; tenancy proceedings typically start at the Amtsgericht ^[4], and in complex legal matters a lawsuit may be necessary under the rules of the ZPO ^[2].

Practical preparation steps

1. Document the current state with photos, measurements and a defect list.
2. Send a formal request to the landlord with plans and a cost estimate.
3. Obtain at least two contractor quotes and check funding options.
4. Hold a meeting and record agreements in writing.

Costs, Funding and Damages

Clarify who bears which costs: small repairs may be the tenant's responsibility according to the lease, while major renovations are usually the landlord's responsibility or require a separate agreement. There are regional and federal grants for accessible adaptations; check with the local housing promotion office or municipality early. Keep all receipts and quotes to avoid later claims.
