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
Landlord’s duty to warn tenants — judgment of 17 January 2018, remitted in part to Charlottenburg Local Court
Key finding
A professional landlord must inform tenants about asbestos it knows of or ought to know of. The court dates that duty to Germany’s asbestos guideline of 1996 — in the judgment: “this duty, which arose in 1996” (translated). A professional landlord had to recognise, “at the latest upon adoption of the Asbestos Guideline in 1996” (translated), that damaged asbestos-containing materials could endanger tenants. A missing warning would be a breach of the duties of care, protection and safekeeping owed under sections 241 and 823 of the German Civil Code. The court ruled on the duty to warn. Charlottenburg Local Court could not depart from that. The rent reduction and repayment claimed for 2005 to 2015, by contrast, stayed dismissed: on her own account, the tenant had removed damaged panels and adhesive, for the most part, in 1992 and 1999; linoleum had covered the floor since, and the floor no longer posed a health hazard. The same judgment drew a line, in a section of its reasoning on damages: as long as floor panels and adhesive were undamaged, there was no defect.
Why it matters
The duty does not follow from the Asbestos Guideline but from the tenancy; the guideline only supplies the date from which a professional landlord must have known the risk. That matters because the guideline expressly covers only weakly bound asbestos products with a bulk density below 1,000 kg/m³ — floor-flex panels are around 1,800 to 2,000 kg/m³ and fall outside it. The court still assumed the duty for exactly this product — conditionally: “Had asbestos-containing floor panels been present in the flat, the omitted warning would constitute a culpable breach […]” (translated). The judgment says “as a professional landlord” (translated); the standard is therefore what a housing company ought to know. Whether the case handler in charge knew is not decisive, the court said: the defendant landlord “would have to set out conclusively what enquiries it made and why it nevertheless could not recognise the dangers threatening its tenants” (translated). Had asbestos materials been used, it had to know that, the court said, if only because it had built the house itself.
Berlin’s state-owned housing companies have documented their asbestos stock internally since 2000 — while tenants renovated, drilled and sanded in ignorance. The judgment concerned a single case; the standard it applies is a role — a professional landlord — not any particular company; it applies to degewo as much as to any other.
For the record: The Regional Court set the first-instance decision aside in part — the declaratory claim for future damage against both defendants and the claim for damages for pain and suffering against the second defendant — and remitted that part to Charlottenburg Local Court for a fresh hearing. There, an expert was to establish whether asbestos-containing panels and adhesive had actually been installed in the flat. It dismissed the remainder of the appeal: the rent-reduction and repayment claims, the pain-and-suffering claim against the first defendant, and the declaratory claim as to damage already incurred all stayed dismissed. The outcome of the remitted proceedings is unpublished. Leave to appeal on points of law was refused.
Where panels are damaged, airborne levels are not decisive — judgment of 2019 (date disputed in the sources)
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 %
Sealed adhesive after panel removal or fully covered adhesive, no indication of fibre 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; Regional Court Dresden, 4 S 73/10 (at least from 2001, weakly bound asbestos)
On top of reduction: €20,000 in damages for the severe psychological burden of knowing about an elevated cancer risk, no physical illness required — the court found “gross organisational negligence”, because the landlord had not examined the building materials although the tenant had written to it about a suspicion in 1991; this was weakly bound asbestos with dust in the flat, not floor tiles (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. Chambers of the Berlin Regional Court draw a hard line where the asbestos stays covered and there are no measurements indicating release: no right to have fully covered 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, where the landlord had already answered and an expert found the laminate covering safe, no further right to information or a material sample (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 (Section 78 (3) no. 4). For Section 326 it runs from the act itself (Section 78a sentence 1); for Section 229 it starts only when the bodily harm occurs (Section 78a sentence 2) — and when that happens in asbestos cases has not been decided. 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 sealed or fully covered asbestos adhesive 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 — about asbestos they know of or ought to know of; that is what the Berlin Regional Court (18 S 140/16) set out for a professional landlord. It dates the landlord’s duty to inform to Germany’s asbestos guideline of 1996. Whether tenants can also demand information is open: in case 65 S 209/17 the chamber held that the information had already been given and denied any further claim to information, or to a material sample, in that case. 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 material is undamaged and no escape of fibres occurs or is to be feared, or where asbestos adhesive is covered, chambers of the Berlin Regional Court have denied a defect (18 S 140/16; the limits).
In documented cases, yes: the Regional Court of Dresden awarded €20,000 for the severe psychological burden of knowing about an elevated cancer risk, even without physical illness. The landlord had not examined the building materials although the tenant had written to it about a suspicion in 1991; the court called this gross organisational negligence (4 S 73/10, a case of weakly bound asbestos with dust in the flat, not floor tiles; see the rates section). For defects that already existed when the lease was signed, the landlord is liable even without fault (Section 536a Civil Code). That presupposes a defect: for undamaged floor panels and adhesive the Berlin Regional Court denied one (18 S 140/16) and affirmed one for damaged panels (18 S 133/15; 66 S 212/18). Risks that, by the standards of science and technology, were not yet recognisable at the start of the tenancy are, under 18 S 140/16, not automatically covered by that no-fault liability.
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 (Local Court Schöneberg, 106 C 282/15). They only have to vacate for the duration of the works in return for replacement housing — and the move is reasonable only if the landlord organises and pays for it. 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 carry a five-year limitation period. For the environmental offence (Section 326) the clock runs from the deposit of the material, not its discovery; for negligent bodily harm (Section 229) it starts only when the bodily harm occurs (Section 78a sentence 2) (why criminal cases run out of time).
The case law is clearer than its enforcement
German courts have set out the duties in individual rulings. What one Berlin state-owned landlord did with those duties is documented here — permit by permit, letter by letter.
