PLU Changed After Buying My Land in Cannes: Can I Still Build?

You bought land in Cannes with the hope of building the home of your dreams. A few months later, the Local Zoning Plan (PLU) was amended: your land is now classified as a natural or agricultural zone, and buildability appears to be lost. You’re furious, at a loss. Yet a solution exists: acquired rights.

What nobody tells you: Article L111-12 of the Urban Planning Code

This article, introduced by the ALUR law, protects property owners who obtained a certificate of urban planning or a building permit before the PLU was changed. It preserves the right to build for 18 months after the zoning document is annulled or amended. Be careful, though: this period runs from the date of the decision by the competent authority.

How do you calculate your rights?

The rule is simple: if you filed a building permit application before the PLU changed, and it complied with the PLU in force at that time, you benefit from an 18-month window to carry out the works. Even if the new PLU prohibits construction, your right is preserved. This period can be extended if you obtained an operational certificate of urban planning.

What should you actually do?

1. Check the date of the PLU change: consult the Cannes municipal council’s resolutions. The change takes effect on the date of publication.
2. Gather your evidence: certificate of urban planning, building permit, acknowledgment of receipt of your application.
3. File your building permit if you haven’t already. Even if the new PLU is now in force, your application will be reviewed under the previous PLU if it was filed before the change.
4. Consult a lawyer or an expert: a professional can help you assert your rights if your application is refused.

A real case in Cannes

Mr. and Mrs. Dupont bought land in the La Bocca district of Cannes in 2022. They obtained an operational certificate of urban planning in January 2023. In March 2023, the town council amended the PLU, rendering their land unbuildable. Thanks to Article L111-12, they were able to file a building permit application before the 18-month period expired. The permit was approved under the previous PLU. Today, their house is under construction.

Frequently Asked Questions

PLU changed after buying land, what should I do?

If the PLU changed after you bought your land, you need to check whether you hold acquired rights (a prior building permit or certificate of urban planning). In some cases, you can build under the previous rules if your project was already authorized. Consult a planning lawyer to assess your situation.

Can I still build if the PLU has changed?

It depends. If the PLU change removed the right to build on your land, you won’t be able to build, unless you hold a still-valid building permit or a favorable certificate of urban planning. Otherwise, you must comply with the new PLU, which may impose stricter restrictions.

My buildable land became non-buildable — do I have any recourse?

You can challenge the PLU change if it is unlawful or infringes on your rights. File an informal appeal with the town council or a formal appeal before the administrative court. It’s advisable to act quickly (within 2 months of publication) and consult an expert.
