What Paris Landlords Should Know About Electrical Inspection in France

France records around 80,000 house fires every year, and roughly a third of them start with the electrical installation. Paris concentrates the risk: most of the city's residential stock was built more than a century before modern wiring standards existed.

That is why French law requires an electrical inspection, known locally as the diagnostic électrique, before you can put an apartment on the rental market. If your property's installation is over 15 years old, the report is not optional. It goes into the lease file, and its absence can cost you far more than the inspection itself.

This guide explains what the inspection covers, when it applies, what it costs in 2026, and what to do when the report comes back with anomalies. If you own a Paris apartment and plan to rent it out, or already do, the sections below will help you check your compliance position in one sitting.

The electrical inspection is a certified safety assessment of a home's private electrical installation, and every landlord whose installation is over 15 years old must attach one to the lease.

A safety check, not a full rewiring audit

The inspector checks whether the installation presents a danger to the people living there. The assessment follows 87 control points defined by the NF C 16-600 standard, covering the main circuit breaker, differential protection, earthing, and the specific safety rules for bathrooms.

One distinction matters here. The report does not verify conformity with the current installation standard; it verifies the absence of identified safety risks. An older installation can pass. A recent one with poor workmanship can fail.

Only a certified diagnostician can produce the report, and the visit is non destructive: nothing is dismantled, no circuit is touched. For a typical Paris apartment, the visit takes about an hour.

When Is an Electrical Inspection Required? The 15-Year Rule Explained

The obligation applies to you if the installation is more than 15 years old at the time of letting.

The reference date is the last certified conformity work or, failing that, the installation date of the electrical panel.

The report joins the DDT (dossier de diagnostic technique), the technical file annexed to every French lease alongside the DPE energy rating, and the gas and lead reports where relevant. For sales, the same document has been required since 1 January 2009, so if you bought your apartment recently, you may already hold a version of it. Check the date before commissioning a new one.

The rules come down to three questions: how long the report lasts, which leases it applies to, and who funds it.

1. Validity: six years for a rental, three for a sale

A rental report is valid for 6 years; a sale report for only 3. The clock starts on the day of the inspection, not the day of the lease. You should also renew early if major electrical works or an incident have affected the installation since the last visit, even when the six years have not run out.

2. Deadlines: what applies to Paris leases since 2018

The rental obligation has applied to every new lease since 1 January 2018, under the framework set by the loi Alur and décret n° 2016-1105 of 11 August 2016. Paris landlords should note the earlier date that usually applies to them: for apartments in collective buildings whose construction permit predates 1 January 1975, the obligation started on 1 July 2017. The rule covers furnished and unfurnished leases alike.

3. Payment: the owner covers it, never the tenant

The cost sits entirely with the landlord, and you cannot pass it on to the tenant. The official Service-Public guidance on the electrical installation report confirms the report must be in the tenant's hands at signature, not sent afterwards. In practice, most Paris agencies will refuse to market a property without a valid file, and that is a protection for you as much as a constraint.

Many Paris apartments are located in buildings constructed long before their current electrical systems were installed. However, the age of the building does not determine whether a diagnostic is required. The relevant question is whether the apartment’s electrical installation is more than 15 years old.

A renovated kitchen or recently painted interior does not confirm that the electrical system has been renewed. Landlords should check previous diagnostic reports, renovation records and any available certificate of conformity before listing the property.

Signs Your Electrical Installation May Need Attention

Visible features that may justify closer professional assessment include:

• Older fabric-sheathed wiring
• Cartridge fuses rather than a modern consumer unit
• Unearthed two-pin sockets
• Heavy reliance on extension leads because of insufficient sockets

These signs do not constitute a diagnosis, and an electrical report is not based on a simple pass-or-fail result. A certified diagnostician must assess the installation and record any anomalies. Reviewing the findings before marketing the apartment gives the landlord time to obtain professional advice and arrange appropriate work where necessary.

An imperfect report is manageable. A missing one is where landlords get hurt.

The legal exposure for landlords

For a sale, the report is informative: the seller has no repair obligation, and the buyer negotiates. A rental works differently. The landlord must correct any anomaly that compromises the decency of the home, under penalty of rent suspension or a court injunction.

Concealment is treated severely. A tenant can seek a rent reduction or the annulment of the lease, refer the case to the DGCCRF fraud office, and a landlord who knowingly hid the situation faces fines of up to €300,000 and up to two years of imprisonment. Those ceilings apply to deliberate deception, not honest oversights, but they show where French judges place the burden.

And there is a quieter risk. A tenant who later discovers a defective installation holds a strong negotiating position for the entire lease, including at the move-in and move-out inspection stage where deposit disputes are decided.

Repair levels and what they cost in 2026

Not every anomaly means rewiring the apartment. French electricians distinguish two levels of intervention:

• Mise en sécurité: a limited intervention that removes identified dangers, keeps sound elements in place, and targets the panel, differential protection and the riskiest circuits first
• Mise aux normes: a fuller upgrade toward the current NF C 15-100 installation standard, usually chosen during a wider renovation

In most cases a Paris apartment with a failed report needs the first, not the second. Budget from a few hundred euros for targeted fixes up to €800 to €2,500 where the panel itself must be replaced, and count 5 to 10 working days for a full rewire of a 70 m² apartment if it ever comes to that.

Three ways to keep the bill down

A little sequencing saves real money here:

1. Use a Consuel certificate if you renovated recently. A conformity attestation issued within the last 6 years replaces the rental diagnostic entirely, so check your renovation paperwork before booking anything.
2. Bundle your diagnostics into one visit. A combined DPE, electricity, gas and ERP pack runs €200 to €300 in 2026, well below the cost of separate appointments. With DPE G rated properties banned from new leases since January 2025, most Paris landlords need the energy visit anyway.
3. Fix strategically, not exhaustively. Ask the electrician to price the anomalies flagged in the report as a distinct scope, separate from comfort upgrades. Not every contractor volunteers that distinction.

Relocation in Paris does not perform electrical inspections; certified diagnosticians do. What we handle is everything around them, which for a distant owner is usually the harder part.

Under our property management service, the diagnostic file sits inside the routine of managing the apartment: scheduling the Cofrac certified professional, opening the door, tracking the six year renewal clock, and briefing trusted electricians when a report lists anomalies. You review one summary instead of chasing four providers across a time zone.
