Landlord Maintenance Obligations in North Rhine-Westphalia

Overview of Landlord Duties

Heating and Hot Water The landlord must ensure the apartment is adequately heatable during the heating season (October 1 – April 30):

• Living rooms: At least 20–21°C during daytime
• Nighttime: At least 16–18°C
• Hot water: Year-round and continuous supply

If the heating fails, the landlord must arrange immediate repair. In case of prolonged failure, the tenant may reduce rent — typical reduction rates for heating failure in winter: 10–50% depending on severity.

Smoke Detectors in NRW (§ 48 BauO NRW) Smoke detectors are legally required in North Rhine-Westphalia:

• Required in: All bedrooms, children's rooms, and hallways serving as escape routes
• Installation responsibility: The owner/landlord must install and keep detectors operational
• Maintenance: The landlord is responsible for functionality; annual testing may be transferred to the tenant via the lease
• Applies to: All residential buildings (new and existing)

Missing smoke detectors can result in fines; in the event of damage, liability risks arise.

Mold: Duties and Liability Mold is one of the most common disputes in German tenancy law

Liability depends on the cause:

The landlord must immediately remediate known structural defects that can lead to mold. The tenant has a duty to report known defects (§ 536c BGB) — failure to report may result in the tenant owing damages.

Structural Maintenance Duties The landlord is responsible for:

• Roof and facade — waterproofing, insulation, drainage
• Windows and doors — sealing, locking mechanisms
• Utility lines (water, drainage, gas, electricity) — functionality and safety
• Stairwells and common areas — lighting, cleanliness, safety
• Elevators — regular TÜV inspections and maintenance

Cosmetic Repairs

Cosmetic repairs (painting walls, sanding floors, etc.) are the landlord's responsibility if the lease does not contain a valid transfer clause

Rigid renovation schedules and pro-rata clauses are invalid under BGH case law. When the landlord is responsible for cosmetic repairs, they must be carried out as needed — when the condition of the apartment requires it.

Minor Repairs Through a valid minor repair clause in the lease, the landlord can transfer the cost of repairs to certain fixtures to the tenant:

• Typical limits: €75–100 per individual repair
• Annual cap: Max. 8% of annual rent (recommended by courts)
• Only for items of daily use (faucets, door handles, etc.)

Rent Reduction for Defects For significant defects, the tenant may reduce rent:

Best Practices for Landlords

• Conduct regular inspections (with tenant consent) for early defect detection
• Test smoke detectors annually and document the results
• Acknowledge maintenance requests in writing and communicate repair timelines
• Keep reliable contractors available for emergencies
• Service the heating system before the heating season
