Practical use cases

1

Landlord sued over defective heating system installation

A landlord in Lyon rented a flat with a newly installed boiler. Six months later, a carbon monoxide leak caused tenant hospitalisation. The installation firm blamed a faulty valve from the manufacturer. The landlord faces a liability claim and must act within the 5-year limitation period for building defects.

Practical application:

This decision underscores that suppliers of defective products can be held liable for consequential damage, like the pesticide case. The landlord should immediately notify the installer and manufacturer in writing, keep all invoices and correspondence, and consult a lawyer before the statutory deadline expires to preserve the right to claim indemnification.

2

First-time buyer discovers hidden defect after purchase

In Bordeaux, a couple bought a 1930s house. Six months later, severe damp appeared due to a defective damp-proof course injected by a specialist firm before the sale. The firm claims an exclusion clause in their contract. The buyers have two years from discovering the defect to bring a legal action.

Practical application:

As in the nurseryman's case, a supplier’s gross negligence (using an unsuitable product) can override contractual exclusion clauses. The buyers should gather the inspection report, contract, and correspondence showing the firm knew of the house's age and damp risks. They must file a claim within the two-year limitation period and seek a preventive legal opinion to avoid missing deadlines.

3

Co-owners dispute over failed roof repair

The co-owners' association in a Marseille apartment block contracted a roofing company to fix persistent leaks. The new membrane failed within 18 months, causing water damage to top-floor flats. The company blames the manufacturer. The association must act within the 10-year construction defect liability period.

Practical application:

Liability extends to the manufacturer of defective materials, even if the installer is at fault. The co-owners' association must retain all meeting minutes, the contract, and expert reports proving the membrane was unfit for the Mediterranean climate. They should notify all parties immediately, instruct a specialised solicitor, and consider a preventive assessment to determine whether the defect falls under the decennial guarantee.
