Landlords in North Rhine-Westphalia are obligated to maintain the rental property in a condition suitable for its contractual use. This duty arises from § 535 BGB (originally effective 1 January 1900) and applies throughout the entire tenancy.

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 (06:00–23:00): At least 20–22°C (BGH, VIII ZR 38/90)
- Nighttime (23:00–06:00): At least 18°C (LG Berlin, 64 S 266/97)
- 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 — for a total heating failure during winter months, reduction rates can reach up to 100% if the property becomes uninhabitable (LG Berlin, 65 S 70/92; LG Hamburg, 307 S 130/01).
Smoke Detectors in NRW (§ 47 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 the detectors
- Maintenance: The tenant (unmittelbare besitzhabende Person) is responsible for ensuring operational readiness, unless the landlord explicitly takes on this duty (common in professional property management)
- 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 (e.g., painting walls) 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. Note that sanding and sealing parquet floors are structural maintenance tasks and do not constitute cosmetic repairs; any clause transferring this duty to the tenant is invalid (BGH, VIII ZR 48/04). 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 cold rent (Nettokaltmiete) (BGH, VIII ZR 38/90)
- Only for items of daily use (faucets, door handles, etc.)
Rent Reduction for Defects
For significant defects, the tenant may reduce rent:
Disputes and Jurisdiction
In the event of maintenance disputes or rent reduction claims, the local District Court (Amtsgericht) where the property is located has exclusive jurisdiction regardless of the amount in dispute (§ 23 Nr. 2a GVG; § 29a ZPO).
Best Practices for Landlords
- Conduct regular inspections (with tenant consent) for early defect detection
- Test smoke detectors annually (if responsible) 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
