Urbanisme 2026 : Attention, les règles changent RADICALEMENT ! (Recours, Délais, PLU)

Planning-law changes in 2026

Benjamin Ingelaere, a lawyer, says that 2026 will significantly tighten procedures for challenging planning decisions, particularly for third parties contesting permits.

• Appeals against building permits: An informal appeal to the town hall must be filed within one month of the permit being posted, down from two months. Filing this appeal will no longer extend the deadline for going to court: the presenter says a court challenge must still be brought within the overall two-month period.
• Challenges to local urban plans (PLUs): Anyone wishing to challenge in court a decision approving or modifying a PLU must first submit observations during the public inquiry through the investigating commissioner. According to the presenter, failing to do so will make a later court challenge inadmissible.
• Interim relief after a permit refusal: Urgency will now be presumed when seeking an interim injunction against a refusal of a building permit. Previously, applicants had to demonstrate urgency.

The presenter describes these reforms as a major change to appeal procedures and part of a broader trend toward strengthening building rights.
