The owners' association is

Application pratique:

Under this case law, the owners' association is strictly liable for such pre-existing defects, regardless of when they occurred. Emma should immediately notify the syndic (building manager) in writing, attaching photos and a surveyor's report if possible, and demand a general meeting vote to approve repairs funded by the association's budget or a special levy. If the syndic refuses to act, she can seek a court order within the applicable guarantee period (typically 10 years from discovery for major defects), so prompt action and record-keeping are essential.

Application pratique:

The decision confirms that the association cannot evade liability by claiming the defect pre-dates the co-ownership regime—it is strictly liable for all building defects. François should formally demand the syndic convene an extraordinary general meeting to vote on emergency repairs; if the syndic delays, François can apply to the tribunal judiciaire for a mandatory injunction. He should compile evidence of the defect and prior complaints, and note that the 10-year building guarantee (décennale) may apply, so he must not let the problem linger.

Application pratique:

As the flat owner, Laurent can hold the owners' association strictly liable for the defect, per this case law. He should urgently document the crack, inform the syndic, and call for a general assembly resolution to fund repairs—if the association delays, he may have to pay for urgent works himself to protect the tenant, then claim reimbursement. Preserving evidence (photos, expert reports, correspondence) is crucial, as is consulting a lawyer if the association disputes liability, because the strict liability principle overrides any argument about the defect's age.
