North Rhine-Westphalia (Nordrhein-Westfalen, NRW) is Germany's most populous state with approximately 18 million residents. Rental law in NRW is based on the national German Civil Code (Bürgerliches Gesetzbuch, BGB), supplemented by state-specific ordinances — most the Tenant Protection Ordinance (Mieterschutzverordnung NRW). Landlords must comply with both federal and NRW-specific regulations.

Key NRW Rental Regulations at a Glance
Security Deposits
Landlords in NRW may charge a maximum of three months' net cold rent (base rent excluding utilities) as a security deposit
Tenants have the right to pay in three equal monthly installments, with the first due at the start of the tenancy. The deposit must be kept separate from the landlord's personal assets — typically in a savings account with a three-month notice period. Interest earned belongs to the tenant. After the tenancy ends, the landlord generally has three to six months to settle and return the deposit. Deductions are only permitted for legitimate claims such as damage beyond normal wear and tear or outstanding utility payments. For more detail, see our Security Deposits guide.
Rent Control and Increases Since March 1, 2025, a new Tenant Protection Ordinance (MietSchVO NRW) has been in effect, expanding coverage from 18 to 57 municipalities
In these areas, new rental agreements may not exceed 10% above the local comparative rent (ortsübliche Vergleichsmiete). For existing tenancies in protected municipalities, rent increases are capped at 15% within three years (reduced from the federal default of 20%). This regulation is valid until February 28, 2030. Exemptions from the rent cap:
- New-build apartments first occupied after October 1, 2014
- Apartments after detailed modernization (first occupancy post-renovation)
- Properties outside the 57 designated municipalities
For more detail, see our Rent Increases guide.
Eviction Procedures German tenancy law distinguishes between ordinary and extraordinary termination:
Ordinary Termination (§ 573 BGB) Landlords can only terminate with a legitimate interest:
- Owner-use need (Eigenbedarf) — for themselves, family members, or household members
- Significant breach of contract — serious lease violations by the tenant
- Economic exploitation — the tenancy prevents reasonable economic use of the property
Landlord notice periods based on tenancy duration: 3, 6, or 9 months. Tenants always have a 3-month notice period.
Extraordinary Termination Without Notice (§ 543 BGB)
- Rent arrears of at least two months' rent
- Severe disturbance of the building community
- Unauthorized subletting
NRW Special Rule: In the 57 municipalities under the Tenant Protection Ordinance, an 8-year eviction lock applies after a rental apartment is converted into a condominium (effective for conversions from March 1, 2025).
For more detail, see our Eviction Process guide.
Required Disclosures Landlords in NRW must provide certain information before or at lease signing:
- Energy Performance Certificate — must be shown during viewings
- Known defects — mold, moisture, noise issues
- Previous rent (in rent-cap areas) — upon tenant request
- Operating cost statements — annual statement within 12 months of the billing period
- CO₂ cost breakdown — allocation based on the tiered model
For more detail, see our Required Disclosures guide.
Maintenance and Habitability Under § 535 BGB, landlords must maintain the rental property in a condition suitable for contractual use
This includes:
- Functional heating and hot water supply
- Weathertight windows, doors, and roof
- Defect-free electrical and plumbing installations
- Working smoke detectors (mandatory in NRW under § 48 BauO NRW)
Cosmetic repairs may only be transferred to tenants through validly worded lease clauses — rigid schedules and pro-rata clauses have been ruled invalid by the Federal Court of Justice (BGH).
For more detail, see our Maintenance Obligations guide.
Late Fees German tenancy law does not set statutory caps on late fees
Default interest is governed by § 288 BGB: 5 percentage points above the base rate for consumer tenants. Contractual flat-rate reminder fees are only enforceable if they are reasonable. Courts have accepted amounts of €2–5 per reminder as customary. For more detail, see our Late Fees guide.
Local Ordinances in NRW Major cities in NRW may have their own regulations or rent indices (Mietspiegel):
- Cologne — qualified rent index; included in tenant protection ordinance
- Düsseldorf — own rent index; receives special tenant protection rules
- Dortmund — rent index last updated April 2024
- Bonn, Münster, Aachen — all among the 57 protected municipalities
Always check your municipality's local ordinances in addition to state law.
