Energy & DPE Compliance Guide - Chamonix

What Chamonix property owners need to know about registration, change-of-use rules and holiday letting in the Chamonix Valley.

DPE Rules & Regulations for properties in Chamonix

Navigating energy ratings in France has become one of the most critical aspects of owning a holiday property. Following the introduction of nationwide regulations (the Loi Le Meur), energy performance requirements directly control whether a property can legally operate as a holiday let (meublé de tourisme).

Do I legally need a DPE (Energy Performance Certificate) for a short-term holiday let?

Yes. A Diagnostic de Performance Énergétique (DPE) is mandatory for all furnished holiday lets in France. It evaluates your property’s energy consumption and carbon emissions, assigning a rating from A (most efficient) to G (least efficient).

Your DPE rating must be disclosed during local registration and displayed on official rental listings.

If you'd prefer not to navigate the DPE registration process yourself, our in-resort property management partner, Chamserve, can manage the entire DPE application process, including arranging a certified, accredited diagnostician to inspect your property

What happens if my property is rated F or G? Can I still rent it out?

The answer depends entirely on when your property was first registered and operated as a holiday let:

• New Holiday Lets (First listed after 20 November 2024): If a property requires a local change-of-use authorization (changement d'usage) and was not an active holiday let before 20 November 2024, it must achieve a DPE rating between A and E.
  Properties rated F or G cannot obtain the required authorization and cannot be rented as new holiday lets.
• Established Holiday Lets (Active before 20 November 2024): Properties that were already lawfully operating as holiday lets prior to 20 November 2024 benefit from a transitional exemption.
  An existing F or G property is not automatically banned today simply because it continues operating, but all holiday lets must achieve at least a D rating by 1 January 2034.

What does this mean if I am buying a new property in the Chamonix Valley?

When purchasing a property, the seller or estate agent (immobilier) will provide a mandatory technical diagnostics pack (DDT) containing the current DPE rating.

If you are buying a property rated F or G with the intention of launching it as a new holiday let, you will not be able to secure the necessary Mairie authorization without first completing energy efficiency improvements.

How can I improve a poor DPE rating (F or G)?

Improving a property's DPE rating not only ensures legal compliance—it also reduces winter heating bills, improves guest comfort, and boosts rental yield.

Common cost-effective upgrades in mountain properties include:

1. Insulation: Upgrading loft, roof, or internal wall insulation.
2. Glazing: Replacing older single/double glazing with high-performance thermal glass.
3. Heating Controls & Systems: Installing modern programmable radiators, heat pumps, or smart thermostats.

Energy & DPE Focus

Navigating Energy Compliance in the Chamonix Valley

Holiday letting in Chamonix and Saint-Gervais remains highly viable and profitable, but staying compliant requires proactive planning.
With French rental laws imposing strict DPE energy ratings and mandatory diagnostic checks, ensuring your property is legally clear to rent is now just as critical as your marketing strategy.

If you are currently purchasing a property, we strongly recommend evaluating its DPE rating and required diagnostics before completing the transaction. Identifying thermal or safety compliance issues early avoids unexpected delays or restrictions on obtaining your changement d'usage authorization.

Beyond energy ratings, successful holiday letting involves a full spectrum of compliance and operational needs:

• SIRET & DECLALOC Registrations
• DPE & Health & Safety Diagnostic Inspections
• Copropriété Rule Audits
• Specialist PNO Insurance & Tourist Tax Classification
• Commercial Yield Optimisation & Professional Marketing
