Cas d'usage pratiques

1

Enclosing a balcony without syndicate approval

As a co-owner of a flat in a 1960s building in Lyon, you want to enclose your 4 m² balcony with glazing to create extra living space, costing around €8,000. The co-ownership regulations prohibit any modification affecting the building's external appearance without prior consent from the syndicate.

Application pratique:

Under this case law, if you proceed without approval and the syndicate demands removal, they won't need to prove financial loss—the breach of the co-ownership regulations is sufficient. Before starting, obtain written authorisation from the syndicate's general meeting to avoid a costly demolition order and potential legal fees.

2

Unauthorised rooftop terrace by a top-floor owner

A co-owner in a 5-storey Bordeaux apartment block has built a wooden deck and pergola on the flat roof, a common area, spending around €15,000. The work altered the building's silhouette and caused water ingress, but the co-owner refuses to restore the roof.

Application pratique:

The syndicate can demand demolition based solely on the breach of the co-ownership regulations, without needing to quantify damages or prove financial loss. As the syndicate, assemble evidence (photos, regulations, expert reports) and instruct a solicitor to seek a court order for removal under the contractual obligation, avoiding prolonged negotiations.

3

Purchasing a flat with an unauthorised conservatory

You're about to buy a ground-floor flat in Nice with a 12 m² conservatory added in 2015 that extends into the communal garden. The seller claims it was 'always there' but cannot provide syndicate approval, and the co-ownership regulations explicitly forbid private use of common areas.

Application pratique:

Before purchasing, demand the seller obtain formal syndicate ratification or negotiate a price reduction to cover potential demolition costs (around €10,000–€15,000). Without approval, the syndicate can compel you, as the new owner, to remove the structure at your expense, with no need to prove loss, as confirmed by this case law.
