Neighbors built similar verandas

Two neighbors built nearly identical 15-square-meter verandas using the same materials, process, and craftsman. Both aimed to improve their homes with more light and space during winter.

One received a city hall letter

A year later, one homeowner received a registered letter from the city hall, while the other faced no issues. The difference stemmed from an administrative step one completed before starting, which the other ignored.

Urban planning declaration required

The letter indicated the veranda should have undergone a prior urban planning declaration, a requirement for any structure over 5 square meters. This allows the commune to ensure compliance with local rules, including distance from neighbors and aesthetic standards in protected areas.

Consequences of skipping the step

If the city hall discovers the irregularity through a neighbor’s report, aerial photos, or routine checks, the homeowner may need to regularize the situation. This could involve submitting a post-hoc declaration, with no guarantee the veranda will be accepted. Demolition or penalties might follow if it violates regulations.

Preventive steps for homeowners

To avoid such issues, homeowners are advised to consult their commune’s urban planning plan, submit a prior declaration, wait for official approval, and keep copies of all documents. This case shows how a minor administrative step can greatly affect a construction project’s legality.
