In an article recently published in Le Particulier (Particulier et Finances Editions), our partner Frédéric Coppinger discusses the “Huwart” law (n° 2025-1129 of 26.11.25), which aims to simplify urban planning rules, often seen as an obstacle to construction.
This reform introduces several relaxations for individuals: expanded exemptions for roof extensions, conversion of premises into housing, and reduced parking requirements. However, as Frédéric Coppinger reminds us, “it is the mayors who will remain the decision-makers”.
Another notable measure: the deadline for a conciliatory appeal against a permit is reduced to one month. A change that, in practice, should be tempered by the still lengthy judicial timelines (up to 4 years).
A reform to watch closely, balancing simplification efforts with persistent constraints on the ground.
