Facade renovation and ravalement on the Côte d'Azur
English-language advice keeps repeating that French law makes you redo your facade every ten years. As a blanket rule, that's a myth. This page covers what the law does require, which colours a commune can impose, when re-rendering obliges you to insulate, and what pushes the price up.

The rule everyone gets wrong
Do you really have to redo your facade every ten years?
Not in the way most sites describe it. French pages keep stating flatly that a ravalement is "obligatoire tous les 10 ans". That's a narrow local rule stretched into a national one.
The national rule is a duty to keep the outside of a building in good repair at all times. It sets no deadline.
The ten-year cycle applies only in Paris and in communes that have opted in, through a prefectoral decree or their own council's decision. Even there, nothing happens automatically. The mairie (town hall) sends the owner an injunction, which typically gives 6 to 12 months to do the work.
We couldn't find a list of Alpes-Maritimes communes that have adopted the rule, so we can't say either way. If a ten-year deadline matters to your plans, email your mairie's service urbanisme and ask. Don't rely on French blog posts claiming it applies everywhere.
The underlying duty still bites. If a facade is cracked, stained or shedding render, the commune can order repairs at any time, ten-year cycle or not.
Colour and planning rules
Which colours can you paint a house on the Côte d'Azur?
Ask the mairie before you buy the paint. Many communes on the coast set an approved palette, a nuancier, in their Plan Local d'Urbanisme. A render colour common two streets away may not be allowed on yours. Changing your facade's colour needs a déclaration préalable (planning declaration), nuancier or not. It's a lighter filing than a permis de construire (planning permission), but a filing all the same.
The stakes rise inside a protected perimeter, the zones drawn around historic centres and listed buildings. Much of Menton's old town sits inside one. There the Architecte des Bâtiments de France has binding authority over colour, render texture and even shutters. If the ABF (the state heritage architects) says ochre and you filed for blue, you repaint in ochre.
File with an exact shade code. Ask the mairie whether a nuancier applies to your address before you order sample panels. In an old town core, allow extra time for the ABF's review.
Get matched with vetted English-speaking installers in your area.
Get quotesWhat to budget
What pushes up the price of re-rendering a Riviera facade?
The wall under the old render decides most of it, and nobody sees that until the loose render is knocked off. Hollow patches, deep cracks and damp all add repair work. Ask each contractor how they'll price repairs found once the old render is off.
On an old stone or rubble wall, ask which render they plan to use. These walls need a lime render that lets moisture out. Cement traps damp behind it, and the render can come away. Lime takes longer to apply, so a much cheaper quote may simply be cement.
Access comes next: the height, a narrow street, scaffolding on the pavement that needs its own permit. A colour or product set by the mairie or the ABF can limit your choice of supplier. Adding wall insulation at the same time changes the price too. Only that part gets 5.5% TVA (French VAT), and plain render and repainting stay at 10%, so ask for separate lines.
Get two written quotes on the same area in m², the same finish and the same preparation, with scaffolding on its own line.
Timing the work
Should you insulate the walls when you re-render, and when must you?
If your walls are solid stone or rubble, as on a lot of older Riviera houses, a ravalement is the moment to think about external wall insulation (ITE). The scaffolding goes up once either way. Split the two jobs across different years and you pay for it twice.
Sometimes the insulation isn't optional. The rule covers heated walls of brick, concrete block or poured concrete. Re-render or re-clad at least half of such a facade (openings excluded) and the law requires you to insulate at the same time. Stone, earth and lime-rendered walls are exempt. So is insulation a professional shows would harm the wall, one that planning or heritage rules block, or one that wouldn't pay for itself within ten years. Ask the contractor which case applies, and have any exemption put in writing.
ITE is more than a repaint. It thickens the wall and changes its look, so it always needs a déclaration préalable. Inside a protected perimeter the ABF can refuse it on a facade of architectural interest, because the extra thickness alters window reveals, cornices and similar details. Whether it's possible depends on where the property sits.
CEE (energy-supplier grants) still funds wall insulation with no residence condition, so second-home owners qualify. Our wall insulation page covers CEE and how ITE compares with internal insulation if the ABF says no.
Permits and paperwork
Two permits for facade work: one for the look, one for the scaffolding
Two separate permissions can apply, and owners tend to forget the second.
The first covers the work itself. Any change to the facade's look (colour, render texture, added insulation) needs a déclaration préalable at the mairie. A repaint in the identical colour and material usually doesn't. The exceptions are protected perimeters and communes that require a filing for every ravalement, so ask the mairie what the PLU says first. Allow extra time inside a protected perimeter, where the ABF has to weigh in.
The second is the permis de voirie (also called an autorisation d'occupation du domaine public). You need it when scaffolding stands on a public pavement or street. In old towns, where facades often sit right on the property line, it's unavoidable. It's issued separately, may carry a fee for the time the scaffolding stands, and needs enough lead time not to hold up a booked contractor.
A contractor used to old town centres will usually raise it unprompted. If yours doesn't and your street is narrow, ask.
Choosing a contractor
What should a written quote for facade work include?
A proper facade devis (written quote) reads like a specification. It should describe the preparation: cleaning method, extent of crack repair, treatment of damp or crumbling patches. It should name the product and finish by reference. It should give the total area in m², list scaffolding on its own line, and say whether the déclaration préalable paperwork is included.
If insulation is part of the job, it needs a line of its own, apart from the render and paint. The two carry different TVA rates, and only the insulation can qualify for CEE.
Ask whether the colour and product match what goes into the déclaration préalable, or are provisional until the mairie or ABF decides. Changing colour after signing can mean a change order.
Ask about the warranty terms too. Render work carries the ten-year garantie décennale (ten-year building insurance) only where it affects the building's watertightness. Otherwise neither the décennale nor the two-year biennale applies, since the biennale covers equipment, not render. Ask what warranty the contractor gives on the finish, and get the devis to say which cover applies to which part.

Questions
Frequently asked questions about facade renovation on the Côte d'Azur
If your question isn't here, send it with your request and we'll answer it directly.
The injunction sets a deadline, typically somewhere between 6 and 12 months. Miss it and you risk a fine, and in some cases the commune has the work done and bills you. Don't sit on the letter: get quotes and start the déclaration préalable straight away, since the paperwork alone can take a couple of months.
A few do. Cannes runs the clearest scheme on the coast: it funds render and paint on buildings in designated sectors that are visible from the street, with no residence or income test. The grant has to be approved before work starts. Elsewhere, ask the mairie. These grants pay for the facade itself, while insulation goes through CEE.
Only the insulation part. Cleaning, render repair and repainting are general renovation work, taxed at 10% on a home more than two years old. If you add external wall insulation, that part drops to 5.5%. Ask for it on its own devis line so the lower rate is plain on the page.
The copropriété (the building's co-ownership). The facade is common property, so the work is voted at the general assembly and the cost is split between owners according to their shares. You can't repaint or insulate your own stretch of the facade alone. If you think the work is overdue, ask the syndic (the building's managing agent) to put it on the agenda.
Usually a month from a complete déclaration préalable, and two months in a protected sector, where the ABF has to give its opinion. If the mairie asks for missing documents, the wait starts once the file is complete. Scaffolding on the pavement needs a separate permis de voirie, so apply for both early.
