How to read German case citations
German decisions are cited by court, case number and date. The courts you will meet on this page: AG (Amtsgericht) — local court, first instance for most tenancy disputes · LG (Landgericht) — regional court, hears appeals in tenancy cases; the Berlin Regional Court decides through numbered chambers (the “65th”, “63rd”, “18th” civil chamber), which do not always agree with each other · OLG (Oberlandesgericht) — higher regional court · BGH — Federal Court of Justice · BAG — Federal Labour Court · BSG — Federal Social Court · VG (Verwaltungsgericht) — administrative court, enforces the Hazardous Substances Ordinance (GefStoffV). Quotations are our translations from the German originals; the case numbers link to the German version of this page, where every ruling is documented with its full-text source.
The three pillar rulings
The duty to inform, the measurement myth, the uninhabitable flat
Duty to inform
Berlin Regional Court, 18 S 140/16
Landlords must disclose known asbestos — judgment of 17 January 2018
Key finding
A professional landlord who knows about asbestos contamination must inform tenants — a duty the court dated to Germany’s asbestos guideline: it existed “at the latest upon adoption of the Asbestos Guideline in 1996” (translated). Its breach is an independent violation of the landlord’s duties and supports claims for health damage. The same judgment drew a line: as long as floor panels and adhesive were undamaged, there was no defect — rent reduction claims were dismissed.
Air measurements do not settle the question — judgment of 25 September 2019
Key finding
Where asbestos-containing material is damaged, the concrete health hazard exists regardless of the fibre concentration currently measured in the air — because even the release of individual fibres can damage health (translated summary). An inconspicuous air measurement is no all-clear.
Why it matters
“Our measurements found nothing” is the standard defence of every landlord. This ruling — and the same court’s finding that sealing or building over damaged panels is “just as dangerous to health as installing them” — takes that defence apart.
Uninhabitable
Local Court Eutin, 27 C 593/15
Fibre release makes a flat uninhabitable — judgment of 20 June 2018
Key finding
“With asbestos there is no effect threshold. Every asbestos fibre can already impair health” (translated). The release of asbestos fibres in the cellar was enough to render the flat uninhabitable. The tenant, who had moved out, was awarded €22,455.83 — including hotel and replacement housing costs — plus a declaration that the landlords are liable for all future material and immaterial damage from the asbestos contact. For the contamination period, no rent was owed at all.
Why it matters
The court also found fault in a familiar pattern: the tenant had warned in writing of respirable fibres two days before the works began; the landlords played it down and had the asbestos-containing duct removed anyway. Knowledge plus inaction — the same sequence documented in the Berlin case.
Rent reduction rates
How much rent reduction for asbestos?
The range runs from zero to full exemption — what decides is the condition of the material, not its mere existence:
Reduction
Situation
Decision
0 %
Firmly bound, undamaged or fully covered asbestos, no measurements indicating release
Berlin Regional Court, 63 S 164/16 · 65 S 220/14
10 %
A single broken asbestos floor tile — normal use of the flat (setting up a shelf) falls within the landlord’s risk
Berlin Regional Court, 65 S 419/10
20 %
Damaged panels — retroactive to the very start of the tenancy, even though the contamination was discovered years later
Berlin Regional Court, 18 S 133/15
50 %
Commercial premises contaminated by demolition works
Higher Regional Court Hamm, 30 U 20/01
Full exemption
Uninhabitability after fibre release — usability of the flat suspended, no rent owed
Local Court Eutin, 27 C 593/15
On top of reduction: €20,000 in damages for the psychological burden of years of exposure and the knowledge of an elevated cancer risk — the landlord had ignored a written warning from 1991 with gross negligence (Regional Court Dresden, 4 S 73/10). And a time limit that helps tenants: the three-year limitation period only starts at the end of the year in which the tenant learns of the contamination; overpaid rent can be reclaimed up to a ten-year cap (Section 199 German Civil Code).
Federal courts
What Germany’s highest courts have decided
Disclosure
Federal Court of Justice, V ZR 30/08
Asbestos must be disclosed unasked — judgment of 27 March 2009
Key finding
Building materials that were customary at the time of construction but were later recognised as harmful to health can constitute a defect “that must be disclosed without being asked” (translated official headnote; decided for a house sale). A seller who fraudulently stays silent loses the protection of any agreed exclusion of warranty. The standard: a defect exists once there is a serious risk that the substances will escape during ordinary use of the property.
Why it matters
Germany’s highest civil court recognised asbestos as a disclosure-triggering health hazard back in 2009. The standard — serious risk during ordinary use — is the same yardstick against which a landlord’s silence must be measured, especially where ordinary use includes an approved do-it-yourself renovation.
The threshold
Federal Court of Justice, VIII ZR 19/13
The honest limit: exposure must be demonstrable — judgment of 2 April 2014
Key finding
The court overturned a Berlin judgment that had granted children of tenants a declaration of liability for future asbestos damage. A declaratory claim requires that damage is to be expected on a reasonable assessment; the court-appointed expert had put the children’s additional tumour risk at “very, very low” (translated). The decisive question is not whether asbestos was present, but how high the demonstrable exposure was.
Why it matters
In the documented Berlin case, this is the ruling the landlord’s counsel relied on — and its actual scope is narrow. It did not decide that landlords never pay; it drew an evidence threshold. Whoever ripped out panels, sanded adhesive or milled screed stands on the other side of that threshold from someone whose flat merely contained a cracked tile. Documentation of the actual exposure decides everything.
After the warning
Federal Labour Court, 8 AZR 769/09 and 8 AZR 471/12
Whoever lets work continue after a warning is liable — 2011 / 2013
Key finding
A city had a building renovated in 1995 whose use as a children’s facility had been ended five years earlier over possible asbestos fibre release. Workers were neither informed nor given protective equipment; the trade inspectorate later found an “extreme exposure to asbestos fibres” (translated) and stopped the works. An employee who is not even ill won a declaration that the city is liable for all future health damage — final and binding. Decisive: a department head let the works continue after being warned of the asbestos hazard.
Why it matters
Employees must prove intent because statutory accident insurance shields employers. Landlords have no such privilege — between tenant and landlord, ordinary civil law applies and negligence suffices. A tenant has to prove less than this worker did.
For families
Federal Social Court, B 2 U 17/19 R
Death does not end the claim — judgment of 16 March 2021
Key finding
A worker with mesothelioma died while his claim for recognition of the asbestos occupational disease was pending. The court held that both special legal successors and heirs may continue the proceedings (translated headnote) — his widow and children could carry the case on.
Why it matters
Asbestos diseases surface decades after exposure; many victims do not live to see their case end. This ruling ensures the claim survives the claimant — essential knowledge for families.
Administrative courts
The ban on covering asbestos
Three courts, one line: asbestos must be removed, not built over. The Administrative Court of Magdeburg prohibited cladding a façade over asbestos-containing joint sealant — the material must be removed “without residue” before any redesign (1 A 149/13 MD, judgment of 24 March 2015, upheld on appeal). The Administrative Court of Arnsberg held that Germany’s Hazardous Substances Ordinance bans “any work on an asbestos-containing part of a building”, including sealing or covering left-over asbestos adhesive after floor panels are removed — mere contact with the substance is enough, no fibre release required (6 K 7190/17, judgment of 8 November 2018; all quotations translated). The Berlin Regional Court added in 2019 that sealing or building over damaged panels and adhesive is as dangerous as installing them. Since December 2024, the ban is spelled out in the ordinance itself: firm covering, building-over and raised constructions on asbestos-containing floor coverings are expressly excluded from the permitted exceptions (Section 11(3) GefStoffV).
Why this matters beyond Germany’s borders: “just cover it up” is the cheapest answer to asbestos everywhere — and German administrative courts have declared it illegal even where nothing is visibly damaged. The full documentation, including the 2012 Berlin renovation permit that demanded exactly this construction, is on the pattern page.
Honest accounting
The rulings tenants lose
A credible overview includes the restrictive line. Berlin’s chambers deny claims where asbestos is firmly bound, undamaged and covered: no right to have sealed adhesive removed without measurements indicating release (65 S 220/14), no defect from adhesive left in the floor after panel removal — the “abstract possibility” of contamination is not enough (63 S 164/16, translated) — and no general right to demand information or a material sample without concrete indications (65 S 209/17). The burden of proof lies with the tenant, and the expert opinion costs money. This is the gap in tenant protection that only a mandatory asbestos register would close — which Germany, unlike France or Poland, does not have.
Criminal law
Why criminal cases run out of time
Negligent bodily harm (Section 229 Criminal Code) and unlawful handling of hazardous waste (Section 326 — asbestos qualifies as carcinogenic waste) both carry a five-year limitation period from the act. The Bavarian Supreme Court held in 2021 that depositing asbestos panels is not a continuing offence: the clock starts when the material is put down, not when it is discovered (204 StRR 341/21) — proceedings were closed as time-barred. The bitter asymmetry: while the criminal clock runs out within five years, the disease clock of the exposed is only beginning — mesothelioma takes decades. How this played out in the Berlin case, where the investigator herself noted the waste offence was “likely long time-barred”, is documented on the criminal case page.
Frequently asked questions
Asbestos and German tenancy law — FAQ
German rulings range from 0 % for undamaged, covered asbestos to 10 % for a single broken tile, 20 % retroactive to the start of the tenancy, and full exemption where fibre release made the flat uninhabitable — each rate with its case number in the table above.
Yes, if they know about it: according to the Berlin Regional Court (18 S 140/16), the duty has existed since Germany’s 1996 asbestos guideline at the latest. But there is no general right to demand information without concrete indications (65 S 209/17), and no national register forces landlords to find out. If you rent in a building from 1960–1993, ask in writing — it creates the paper trail courts later care about.
Where panels are damaged or fibres were released, yes — the justified fear of harm is itself enough (OLG Hamm, 30 U 20/01; Local Court Eutin). Where asbestos is firmly bound, undamaged and covered, Berlin courts regularly deny a defect (the limits).
In documented cases, yes: the Regional Court of Dresden awarded €20,000 for the psychological burden of years of exposure after the landlord had ignored a written warning from 1991 with gross negligence (4 S 73/10; see the rates section). For defects that already existed when the lease was signed — such as built-in asbestos — the landlord is liable even without fault (Section 536a Civil Code).
No. Where asbestos-containing material is damaged, the hazard exists regardless of the fibre concentration currently measured — even individual fibres can damage health (Berlin Regional Court, 66 S 212/18). No safe threshold has ever been established. Conversely: without damage or measurements, courts often deny a defect.
Not during renovation works: administrative courts have classified building over asbestos and sealing asbestos-containing adhesive residues as prohibited work (VG Magdeburg, 1 A 149/13 MD; VG Arnsberg, 6 K 7190/17). Since December 2024 the ban is spelled out in Section 11(3) of the Hazardous Substances Ordinance.
Yes: tenants must tolerate asbestos remediation as a maintenance measure — including a temporary move into replacement housing provided and paid for by the landlord (Local Court Schöneberg, 106 C 282/15). The works must be announced in good time under Section 555a of the Civil Code.
Document everything: what you did, when, photos, witnesses, any permit from the landlord. The Federal Court of Justice made demonstrable exposure the decisive threshold (VIII ZR 19/13) — and also ruled that courts may not cut off expert evidence on formal grounds (VIII ZR 97/15). The limitation clock only starts when you learn of the contamination.
Tenancy claims: three years from the end of the year in which you learn of the contamination; overpaid rent can be reclaimed up to a ten-year cap (Section 199 Civil Code). Criminal offences are time-barred five years after the act — the clock runs from the deposit of the material, not its discovery (why criminal cases run out of time).
