GermanyCan I Reduce Rent for Apartment Defects?
Yes — under German law (BGB § 536), you can reduce rent if your apartment has a defect that significantly impairs its use. The reduction applies automatically from the moment the defect arises and lasts until it's fixed.
What the Law Says
German law gives tenants strong protection when their rented apartment is defective. The core rules are in the German Civil Code (BGB), which treats rent reduction as a direct legal right — not something requiring prior agreement or court approval.
Under BGB § 535(1), your landlord must hand over the apartment in a condition suitable for the agreed use — and keep it that way throughout the lease. This includes structural integrity, basic utilities, safety, and habitability.
BGB § 536(1) is the key provision for rent reduction: if the apartment has a defect that either existed at move-in or arises during the tenancy — and that defect fully or partially impairs its suitability for the agreed use — you may suspend full rent payment. If the defect completely prevents use (e.g., no heating in winter, major mold, or total loss of electricity), you're fully exempt from paying rent for that time. If the defect only partially impairs use (e.g., one broken bathroom, persistent noise, or drafty windows), you pay only an appropriately lowered rent — determined case-by-case based on severity and impact.
Importantly, trivial defects don't qualify. BGB § 536(1a) creates a special exception: if the defect results from energy-efficient modernization work (like new insulation or windows under § 555b No. 1), rent reduction is excluded for up to three months — even if the apartment becomes temporarily less usable.
BGB § 536(4) adds crucial tenant protection: any clause in your lease trying to waive or limit your right to reduce rent in residential tenancies is automatically invalid. You cannot sign away this right.
Statutory TextDurch den Mietvertrag wird der Vermieter verpflichtet, dem Mieter den Gebrauch der Mietsache während der Mietzeit zu gewähren. Der Vermieter hat die Mietsache dem Mieter in einem zum vertragsgemäßen Gebrauch geeigneten Zustand zu überlassen und sie während der Mietzeit in diesem Zustand zu erhalten.

Statutory TextHat die Mietsache zur Zeit der Überlassung an den Mieter einen Mangel, der ihre Tauglichkeit zum vertragsgemäßen Gebrauch aufhebt, oder entsteht während der Mietzeit ein solcher Mangel, so ist der Mieter für die Zeit, in der die Tauglichkeit aufgehoben ist, von der Entrichtung der Miete befreit. Für die Zeit, während der die Tauglichkeit gemindert ist, hat er nur eine angemessen herabgesetzte Miete zu entrichten. Eine unerhebliche Minderung der Tauglichkeit bleibt außer Betracht.

What Courts Have Said
German courts interpret 'defect' broadly — including issues beyond the apartment itself, like environmental disturbances caused by third parties or neighboring construction.
Persistent, severe noise and dust from ongoing construction on adjacent land — which began after the lease started — constituted a rental defect. The court ruled this impaired the apartment's suitability for residential use and entitled the tenant to rent reduction, even though the disturbance came from outside the building and wasn't caused by the landlord.
What to Do
Document the defect thoroughly: take dated photos/videos, note dates/times of issues (e.g., 'no hot water since 12 May'), and keep records of all communication with your landlord.
Notify your landlord in writing (email or letter with proof of delivery) describing the defect and requesting repair — cite BGB § 536 to signal your intent to reduce rent if unresolved.
Only reduce rent after giving notice and if the defect remains unaddressed. Calculate a reasonable reduction (e.g., 20% for one unusable room; 30% for no heating in winter) — avoid arbitrary cuts.
Pay the reduced amount clearly labeled (e.g., 'Rent for June — reduced by 25% due to mold in bathroom per BGB § 536') and retain all payment records.
