Do you see the wording “property not subject to an EPC” in a listing? Can a property described as “not subject to an EPC” be sold or rented without any additional formalities? How can you check that this wording is not being used to unlawfully bypass the requirement?
This article explains, step by step, what it means for a property to be exempt from the EPC requirement under article R126 15, why certain categories of properties are exempt, how this differs from a blank EPC or an invalid EPC, and what steps to take to secure your sale, rental, or purchase.
The term property not subject to an EPC refers to an exemption provided by law, explained below with reference to article R126 15. A common alternative wording is exempt from the EPC, which has the same legal meaning. This guide details the exemption cases, the risks, the evidence checklist to gather, and the practical steps to follow. If you have any questions, contact your local real estate advisor for personalized support and a free property valuation.
Understanding the wording “property not subject to an EPC”
Property not subject to an EPC: definition
The wording “property not subject to an EPC” means that the property is legally exempt from the energy performance certificate requirement. It does not have to undergo this assessment before a sale or rental. This exemption is based on legal criteria defined by article R126 15 of the French Construction and Housing Code. It is a legal exemption, not an administrative omission.
In principle, the EPC applies to any enclosed and covered building or part of a building. Exceptions include non heated buildings, temporary structures, small detached buildings, second homes occupied only occasionally, certain agricultural or industrial premises, listed historic monuments, and places of worship. Since the 2021 EPC reform, the EPC has been legally enforceable from July 1, 2021. The surveyor must submit the EPC to the ADEME EPC Audit observatory, and the report includes a 13 digit identification number and the EPC XML file. As a general rule, the EPC remains valid for 10 years.
Three concepts are often confused: exemption, meaning a property exempt from the EPC, a blank EPC, which was an old practice no longer allowed for homes since 2021, and an invalid EPC, meaning an expired or non compliant certificate. An exemption is a matter of law, whereas the other situations indicate a missing or outdated certificate.
Clear definition: what does “property not subject to an EPC” mean?
Saying that a property not subject to an EPC is exempt from the EPC means that the owner is not legally required to provide the certificate for a sale or rental. Quick examples include a listed historic monument, a place of worship, a non heated building, or a second home occupied less than 4 months per year. The full list and detailed criteria appear in the “Detailed list” section below.
Legal basis and references: article R126 15 and the regulatory framework
Article R126 15 of the French Construction and Housing Code sets out the principle and the exceptions. The EPC must be included in the technical diagnostics file for a sale or rental. The surveyor sends the EPC to the ADEME EPC Audit observatory, which issues a 13 digit number. Without this number and the EPC XML file, the document is not valid. The standard validity period is 10 years, except in specific cases set out by the regulations. Consult Legifrance, the Ministry website, and the ADEME observatory to check the legal texts and official templates.
Why some properties are exempt from the EPC
Cases of EPC exemption are based on two main principles: the technical limitations of the calculation method and the relevance of the information according to the actual use of the building. The so called 3CL method is based on the building envelope, systems, and uses. It requires data on heating, domestic hot water production, and ventilation.
When these elements are missing, such as in a non heated building, a building heated only by an open fireplace, or a building with no cooling system, the algorithm cannot produce a reliable estimate. Likewise, for temporary or non residential uses, the energy indicator becomes less relevant. The authorities have therefore created exemptions that take into account both feasibility and usefulness.
Be careful: the reason for exemption must be justified and documented. Incorrect classification exposes the owner to the risk of reclassification, investigation by the DGCCRF, and legal disputes for EPC fraud. Keep supporting documents and, if possible, a written statement from a certified surveyor.
Technical limitations: the 3CL method and the data required
The 3CL method relies on three components: the building envelope, meaning insulation and walls, the systems, meaning heating, domestic hot water, and ventilation, and the building uses. To calculate the energy and climate label, the surveyor enters the type of energy used, the installation year, and the efficiency of the equipment. Without this information, the calculation is impossible or unreliable.
This is why a building heated only by an open fireplace or with no fixed heating system may be considered not subject to an EPC. However, the presence of portable heaters or installed air conditioning may make the exemption invalid. A certified surveyor will assess the situation and indicate which supporting evidence is required.
Use based logic: when the EPC is not relevant
The EPC is intended to provide information on theoretical energy consumption for standard use. For a residence occupied less than 4 months per year, or for premises mainly used for economic purposes such as an agricultural shed or workshop, the energy reading is less relevant. Temporary constructions intended to be used for 2 years or less also fall under this logic of non relevance.
However, the authorities check the consistency between the declared use and the actual use. If the property is used as a permanent residence, an EPC may be required even if it was initially presented as exempt.
Detailed list of properties not subject to the EPC without an energy rating
Here are the most common categories of properties not subject to the EPC, along with criteria, pitfalls, and practical examples. Always keep written proof to justify the exemption.
Properties with no heating or heated only by an open fireplace
Second homes and seasonal rentals occupied less than 4 months per year in total
Temporary constructions intended to be used for 2 years or less, such as show homes, exhibition pavilions, or site accommodation
Detached buildings with a floor area of less than 50 square meters, such as garden sheds, autonomous chalets, mobile homes, or tiny houses
Agricultural, industrial, or artisanal buildings not used for residential purposes, if the energy consumption related to human occupation is negligible
Listed or registered historic monuments and places of worship
Properties with no heating or heated only by an open fireplace
The exemption applies if the building is genuinely unheated or if the only fixed heating equipment consists of open fireplaces, and if there is no cooling system. Portable radiators or installed air conditioning often make the exemption inapplicable.
Accepted proof includes a technical description, low energy bills, photographs, and a written statement from a certified surveyor. Without these documents, the buyer or the authorities may challenge the classification.
Second homes and seasonal rentals occupied less than 4 months per year
Second homes and furnished tourist rentals occupied for less than 4 months per year in total may be exempt from the EPC. The calculation is based on the cumulative number of days of occupation, whether consecutive or not.
Example: a 25 square meter studio rented for 90 days per year, around 3 months, may be exempt from the EPC if the owner provides contracts, platform extracts, and an occupancy calendar. If the occupancy exceeds 120 days per year, the EPC becomes necessary for rental listing and for sale.
Temporary constructions and show homes
Temporary constructions intended for use for 2 years or less, such as site accommodation, show homes, or exhibition pavilions, may be exempt. The condition relates to their temporary nature and must be supported by documents such as permits, fixed term contracts, or technical notices.
A common pitfall is that if the use becomes permanent, the exemption no longer applies and an EPC may be required.
Detached buildings under 50 square meters
Detached structures with a floor area of less than 50 square meters may be exempt. Examples include a garden shed, an autonomous chalet, a mobile home, or a tiny house outside the scope of a main residence. Be careful: an apartment of less than 50 square meters in a collective building is not exempt.
Agricultural, industrial, or artisanal buildings not used for residential purposes
Agricultural, industrial, or artisanal buildings may be exempt if the energy used for human occupation is negligible compared with the economic activity. Useful documents include energy bills, a description of use, and plans. If the premises are fitted out as offices or a reception area, the EPC may apply.
Historic monuments and places of worship
Listed or registered historic monuments and places of worship benefit from an exemption because of heritage related constraints. If part of the building is used as a dwelling, that part may still require an EPC. Provide listing orders and heritage documents to justify the exemption.
EPC not mandatory: particular cases depending on use and type of transaction
The exemption must be assessed according to the type of transaction: sale, rental, off plan sale, co ownership, or tertiary property. The EPC is included in the technical diagnostics file for a sale or rental. For new buildings, the relevant document is the new build EPC or builder’s EPC.
In co ownership buildings, a collective building EPC may be carried out and used to generate individual EPCs by sampling. The co ownership manager must provide collective data such as collective heating and metering. From 2026, the EPC requirement for co ownerships with fewer than 50 units has come into effect under the applicable regulations.
Sale versus rental: separate obligations
For a sale, the EPC must be attached to the preliminary sale agreement and to the technical diagnostics file. For a rental, the energy and climate label must appear in the property listing. The timeline of rental bans targets energy inefficient properties: the threshold of 450 kWh per square meter per year, class G from 2025, class F in 2028, and class E in 2034. Landlords must anticipate these changes.
New properties, off plan sales, and builder’s EPC
For new constructions with permits issued after July 1, 2007, the developer must provide a projected EPC or builder’s EPC based on the thermal study. The developer delivers the document when the property is handed over, and it is valid for 10 years except in specific cases.
Co ownership properties and collective building EPC
The surveyor may carry out a collective building EPC by visiting all units or a representative sample. Individual EPCs can then be generated automatically. A co owner who has carried out significant works may request an individual EPC in order to highlight those improvements. The co ownership manager must provide the required collective information.
Tertiary properties and commercial premises: what differences?
The tertiary EPC applies to commercial premises and offices. It uses specific energy label models. Display obligations exist for certain public buildings above 250 or 500 square meters. Sector specific exemptions may apply depending on the use and the low level of human occupation.
Practical consequences for sellers, buyers, and landlords
A property not subject to the EPC may be sold or rented, but the wording must be clear and justified. In a listing, stating “property not subject to the EPC” and indicating the reasons and available evidence reassures the market. By contrast, an unjustified absence of an EPC exposes the parties to legal and commercial risks.
Since the 2021 reform and the enforceability of the EPC, buyers or tenants may take legal action. In cases of clear fraud, criminal penalties may reach a fine of 300,000 euros and 2 years of imprisonment. The DGCCRF monitors practices, and a non certified surveyor may also face sanctions. A notary may also incur liability if they fail to act.
Sanctions, enforceability, and legal risks
The enforceability of the EPC means that the information in the certificate can be challenged in court. Investigations target EPC fraud. In cases of deliberate misconduct, the person responsible may face criminal penalties and civil claims. To reduce risks, build a complete file and ask for the opinion of a certified surveyor.
Impact on value and access to financial aid
A missing EPC or a poor energy rating such as F or G can weigh on the sale price and may restrict access to financial aid schemes such as MaPrimeRénov’ or France Rénov’. For homes rated F or G, a mandatory energy audit and a package of renovation works may be necessary to qualify for assistance. The cost of an EPC generally ranges from 100 to 250 euros.
A brief practical example: a 25 square meter seaside studio rented seasonally for 90 days per year. Analysis: occupancy of around 3 months means exemption may be possible if the owner can provide contracts, platform extracts, and a calendar. If the occupancy exceeds 120 days per year, the EPC becomes mandatory for rental listing and may affect both the listing and access to financial aid. Indicative EPC cost: around 100 to 250 euros.
How to check and justify that a property is genuinely not subject to the EPC
Before publishing “property not subject to the EPC,” prepare a file of supporting evidence. Consult a certified surveyor to obtain a written opinion, and if there is legal uncertainty, ADIL can provide free advice. Check the ADEME EPC Audit observatory for any existing EPCs.
Title deed and cadastral plan
Plans and floor area calculations under article R111 22
Building permit and technical notice for temporary constructions
Rental contracts, platform extracts, and occupancy calendar for a second home
Historic monument listing orders
Energy bills and meter readings for agricultural or industrial buildings
A written statement from a certified surveyor supporting the exemption
A copy of the EPC if one exists, with the 13 digit ADEME number and the EPC XML file
Documents and evidence to gather
Key documents include the title deed, plans for floor area calculation, contracts and an occupancy calendar under the 4 month per year rule, heritage listing documents, bills, and statements from the co ownership manager. These documents make it easier for the surveyor to validate the exemption and protect the seller in the event of an inspection.
Who should you consult? Surveyor, ADIL, real estate advisor
Use a certified surveyor whose official directory is available online. Check the surveyor’s certification, professional insurance, and where applicable Cofrac accreditation. ADIL provides free local legal advice. Your local real estate advisor, for example at Optimhome, can help prepare the file, position the listing correctly, and connect you with surveyors.
To secure the classification of your property, ask for assistance from a local Optimhome advisor who knows which documents are expected and what buyers are looking for.
Recent developments and trends from 2024 to 2026
The 2021 EPC reform made the EPC legally enforceable. The order of March 25, 2024 adjusted thresholds for small properties under 40 square meters. The 2025 and 2026 orders strengthen surveyor certification, introduce an EPC QR code linked to the observatory, and amend the 2026 electricity coefficient. The EPC requirement for co ownerships with fewer than 50 units is scheduled to apply. Cofrac and DGCCRF inspections are increasing to combat EPC fraud.
Your local real estate advisor follows these developments and can help you update the status of your property and secure the transaction.
What should you do if your property is marked “not subject to the EPC” in the listing?
If you are a buyer or tenant, ask for the supporting documents listed above. If you are a seller, prepare the checklist and request a written opinion from a certified surveyor. To reassure the market, you may also consider a voluntary EPC even if the property is officially exempt.
If there is any uncertainty, contact ADIL or your local Optimhome advisor for a review of the situation and personalized support.
Conclusion
The wording “property not subject to the EPC” corresponds to a legal exemption under article R126 15 and must be supported by reliable documents.
Do not confuse exemption, a blank EPC which was an old practice, and an invalid EPC which means an expired certificate.
Keep title deeds, plans, occupancy calendars, heritage documents, and bills, and obtain a written opinion from a certified surveyor.
A “not subject” property that is poorly documented exposes the parties to inspections, claims, and commercial consequences.
The reforms from 2021 to 2026 strengthen enforceability, surveyor certification, and introduce technical adjustments.

FAQ
Can a property described as “not subject to the EPC” be sold?
Yes. A property that is legally exempt from the EPC can be sold, provided the exemption is justified with supporting documents relating to its size, usage period, or heritage status. Without proof, the absence of an EPC creates both commercial and legal risks. Have the situation checked by a certified surveyor and your local advisor.
How can you prove that a property is genuinely exempt from the EPC?
Gather the title deed, plans and floor area calculations, an occupancy calendar, heritage status documents, statements from the co ownership manager, bills, and a written opinion from a certified surveyor.
What is the difference between “not subject to the EPC” and a “blank EPC”?
“Not subject” means there is a legal exemption. A blank EPC was a certificate with no usable data. Since 2021, blank EPCs are no longer accepted for residential properties. These situations are legally distinct.
Are seasonal rentals still exempt from the EPC in 2026?
Under the current rule, second homes and furnished tourist rentals occupied less than 4 months per year may be exempt. This rule may change, so keep proof of occupancy and seek advice from a surveyor or local advisor.
What documents should you ask the seller for to secure a transaction?
Ask for the EPC if one exists, with the 13 digit ADEME number and the EPC XML file. Otherwise, require proof of exemption such as contracts, plans, heritage status documents, the full technical diagnostics file, and a written opinion from a certified surveyor.
What does the seller risk if they fail to provide an EPC when it is required?
Civil and criminal penalties are possible. In cases of clear fraud, the penalties may include a fine of 300,000 euros and 2 years of imprisonment. Because the EPC is legally enforceable, the buyer may also bring a liability claim.
Can you request an EPC voluntarily even if the property is exempt?
Yes. A voluntary EPC carried out by a certified surveyor is often recommended in order to reassure buyers or tenants and enhance the property, even if it is officially exempt.
What does “not subject to the EPC” mean?
The wording “not subject to the EPC” means that the property benefits from a legal exemption from the energy performance certificate requirement. It does not mean that the owner forgot to obtain the EPC, but rather that the dwelling or building falls within an exemption case provided by the regulations, especially article R126 15 of the French Construction and Housing Code. It is therefore a specific legal situation, distinct from an old blank EPC or an invalid EPC.
In what cases is the EPC not required?
The EPC is not required for certain categories of property that are expressly exempt. This includes certain non heated properties, buildings heated only by an open fireplace, certain second homes occupied less than 4 months per year, temporary constructions intended for short term use, detached buildings under 50 square meters, certain agricultural, industrial, or artisanal premises not used for residential purposes, as well as historic monuments and places of worship. However, each case must be supported by concrete evidence.
Why can a property be not subject to the EPC?
A property may be not subject to the EPC either because the calculation method is not technically relevant or because the actual use of the building does not justify the assessment. For example, where there is no usable fixed heating system, or where the building is used only occasionally, the EPC loses much of its practical relevance. The law therefore provides exemptions for such situations, but they must be thoroughly documented in order to avoid any dispute during a sale or rental.
