Facade renovation in France: every 10 years

Which communes are concerned?

Article L126-2 automatically covers Paris, then “the communes appearing on a list drawn up by decision of the administrative authority, on the proposal or after the binding opinion of the municipal councils”. Service-public.gouv.fr presents this list as set by arrêté préfectoral (prefectoral order) and cites Paris, Lyon and Nantes among others.

To find out whether your commune is concerned, service-public.gouv.fr advises asking the town hall’s planning department or checking its website. In communes not covered, “no frequency is laid down” for facade renovation.

Facade renovation means restoring the external walls and the visible elements of the facade: external joinery (windows, shutters, louvred shutters) and ironwork (service-public.gouv.fr). Between two renovations, facades must be kept clean, which may require one-off repairs, cleaning or localised works.

The order procedure, step by step

Facade renovation is not triggered by an anniversary date: it is imposed by the mayor, through a reasoned order that takes into account the condition of the building and how it fits into the urban environment (service-public.gouv.fr). Article L126-3 then sets the timetable:

When the mayor has the works carried out automatically, the commune advances the costs, then recovers them “as for direct taxes” (article L126-3).

In a co-ownership building

The mayor’s arrêté is validly served on the owners’ association alone, through the syndic (building manager), who must inform each co-owner without delay by registered letter with acknowledgement of receipt (article L126-3). Facade renovation costs are shared among co-owners according to their tantièmes (ownership shares) (service-public.gouv.fr).

Penalties

An owner who has not carried out the works within the deadlines of article L126-3 “is punishable by a fine of €3,750” (article L183-12, in force since 1 July 2021). On top of this comes the risk of works carried out automatically, the cost of which remains payable by the owner.

Planning permission and insulation: two rules not to forget

Prior declaration. A like-for-like facade renovation, without changing colour or materials, is exempt from planning authorisation. However, a déclaration préalable (prior declaration) is required if you change the external appearance, if the building is in a protected area or is a protected building, or if the commune has decided to make facade renovation subject to authorisation (service-public.gouv.fr; articles R*421-17 and R*421-17-1 of the code de l’urbanisme, Planning Code). External wall insulation always requires a prior declaration. In Paris, the application can only be filed online with the Bureau accueil et service à l’usager (Basu, the user reception and service office).

Obligation to insulate. A “major” facade renovation covering at least 50% of the facade, excluding openings, of a heated building requires the renovated walls to be insulated (service-public.gouv.fr, verified 20 June 2025). The obligation covers walls in fired clay, bricks or industrial concrete blocks, poured concrete or metal cladding. It does not apply to facades in stone, raw earth, cob, wood or traditional lime render. An exemption is possible in particular if a document establishes a payback period of more than 10 years. To make external insulation easier, the town hall may allow a projection of 30 cm beyond the siting rules of the PLU (local development plan), and the owner benefits from a right to overhang the neighbouring land by 35 cm at most.

Which professional to consult

Before buying in a building, the notaire (notary) can check whether a facade renovation order or prescription arrêté applies to the facade, and the agent immobilier (estate agent) can send you the latest minutes of the assemblée générale (owners’ general meeting). If external insulation encroaches on a property boundary, the géomètre-expert (chartered surveyor) can establish the exact boundaries with the neighbouring land.
