Property Surveys in Martinique: What Every Seller Needs to Know
Selling a property in Martinique is not something you can improvise. Before signing any preliminary agreement, the seller is legally required to compile a Technical Diagnostic File (Dossier de Diagnostic Technique – DDT), which serves as the property's health and technical passport. This file, which must be handed over to the buyer, is a legal prerequisite for any valid sale and, if incomplete, may expose the seller to legal action for concealed defects.
Martiinique, as a French overseas department with a tropical climate and specific natural hazards, presents particularities that make certain surveys even more critical than in mainland France. The Cabinet Laurent Valère, a trusted real estate and expert agency on the island since 1985, presents this comprehensive guide to help you approach your sale with complete peace of mind.

What Is the Technical Diagnostic File (DDT)?
The DDT brings together all reports produced by certified surveyors prior to listing a property for sale. It must be appended to both the preliminary sale agreement and the notarial deed signed before the notary. Its contents vary based on:
- The type of property (house, apartment, land)
- The year of construction
- The geographical location
- The presence of specific installations (gas, electricity, sanitation)
In Martinique, several location-specific surveys are added to the national list, reflecting the island's unique geographical and climatic context.

Mandatory Surveys for Any Sale in Martinique
1. Energy Performance Certificate (DPE)
The DPE has been mandatory for all sales since 2006. It assesses the property's energy consumption and greenhouse gas emissions, assigning a rating from A (highly efficient) to G (very inefficient).
Since 1 July 2021, the DPE has been fundamentally reformed: it is now legally binding, meaning buyers can take legal action against sellers if the results prove inaccurate. The DPE remains valid for 10 years, unless significant renovation works have been carried out.
Martinique specificity: The DPE calculation in Martinique accounts for cooling (air conditioning) rather than heating. The island uses its own evaluation grid adapted to the tropical climate, distinct from that used in mainland France. A heavily air-conditioned apartment may therefore be rated F or G despite apparent comfort.
2. Termite Survey
This is one of the most important surveys in Martinique. The law of 8 June 1999 requires a termite survey in all areas declared at risk by prefectoral order. Crucially, the entire territory of Martinique is classified as a termite risk zone under the prefecture's standing order.
In practice: every property sold in Martinique must undergo a termite survey, without exception. This document is only valid for 6 months — one of the shortest validity periods of all diagnostic reports — and must therefore be carried out close to the signing of the preliminary agreement.
If termites are detected, the seller must disclose this to prospective buyers. A declaration to the town hall is also mandatory. Termites cause considerable damage to Martinique's building stock every year, particularly to the timber structures of traditional Creole houses.
3. Asbestos Survey
Mandatory for all properties whose building permit was issued before 1 July 1997, the date when asbestos was banned in France. This material, long used for insulation and roofing, poses serious health risks when it deteriorates.
In Martinique, many buildings constructed between the 1960s and 1990s contain asbestos, particularly in:
- Fibre-cement roofing
- Vinyl floor tiles
- Ventilation ducts
- Sprayed coatings
The asbestos survey is valid indefinitely if carried out after 1 April 2013 and no asbestos is found. If asbestos is detected, periodic reassessment or removal works may be required.
4. Lead Paint Survey (CREP)
The Lead Exposure Risk Assessment (Constat de Risque d'Exposition au Plomb – CREP) is mandatory for properties built before 1 January 1949. Lead was widely used in old paints and can be particularly dangerous for young children (lead poisoning).
The CREP is valid for 1 year if lead is found above regulatory threshold concentrations, or indefinitely if no lead is detected.
5. Electrical Installation Survey
Mandatory when the electrical installation is more than 15 years old. This survey checks the compliance and safety of electrical equipment. In Martinique, where storms and voltage fluctuations are frequent, installations can deteriorate more rapidly than in mainland France. Valid for 3 years in the context of a sale.
6. Gas Installation Survey
Mandatory when the gas installation is more than 15 years old. While mains gas is less widespread in Martinique than in metropolitan France, many properties use gas cylinders or propane installations. Also valid for 3 years.
7. Natural and Pollution Risk Assessment (ERP)
Formerly known as ERNMT, the ERP is one of the most strategically important documents in Martinique. It informs the buyer of the natural and technological risks to which the property is exposed.
In Martinique, the risks covered are particularly numerous:
- Seismic risk: Martinique is classified in seismic zone 5 (the highest), defined as "high"
- Volcanic risk: near Montagne Pelée and the Pitons du Carbet
- Cyclone risk: the island is regularly affected by hurricanes or tropical storms
- Marine flooding risk: for properties near the coast or in low-lying areas
- Landslide risk: slides, collapses
- Tsunami risk
The ERP must be drawn up based on current prefectoral orders and kept up to date. Valid for 6 months. Since the 2021 Climate and Resilience Act, sellers must also inform buyers of any insurance-compensated claims related to natural disasters that have affected the property.
8. Non-Collective Sanitation Assessment
Mandatory if the property is not connected to the public sewage network. In Martinique, a significant proportion of properties — particularly in rural areas or the hills — rely on autonomous sanitation systems (septic tanks, etc.). Valid for 3 years.

Situation-Specific Surveys
Dry Rot (Mérule) Assessment
Although not legally mandatory in Martinique (unlike certain areas of mainland France), dry rot — a destructive wood-decaying fungus — thrives in warm, humid environments. In Martinique, areas prone to damp may be affected. A preventive inspection is strongly recommended for older timber properties.
Carrez Law Measurement
Mandatory only for co-ownership lots. This measurement certifies the private floor area of the property. If the actual surface is more than 5% below the declared area, the buyer may seek a proportional price reduction within one year of the sale.

Who Can Carry Out These Surveys?
Only certified surveyors accredited by a recognised body (COFRAC) may produce these reports. Several approved surveyors operate throughout Martinique. The Cabinet Laurent Valère can refer you to trusted professionals with whom it has established long-term working relationships.
Beware of abnormally low prices: a poorly conducted survey can have serious legal consequences. Make sure the professional is familiar with the specificities of Martinique's building stock.

How Much Do Surveys Cost in Martinique?
Fees vary depending on the service provider and property size, but here are approximate ranges for Martinique:
- DPE: €100 to €200
- Termites: €100 to €180
- Asbestos: €100 to €250
- Lead: €100 to €200
- Electricity / Gas: €80 to €150 each
- ERP: often included in packages, or €30 to €60
Many surveyors offer multi-survey packages at preferential rates. For a standard property in Martinique, budget between €400 and €800 for the complete file.
Good to know: Survey costs are borne by the seller. They may be deducted from rental income if the property was rented before the sale.

Legal Consequences of an Incomplete or Inaccurate DDT
Omitting a survey or providing an erroneous report exposes the seller to:
- Cancellation of the sale at the buyer's request
- A reduction in the sale price
- Legal action for fraud or concealed defects
- Damages payable to the buyer
Since the 2021 DPE reform, the energy performance certificate is legally binding, further strengthening the seller's liability.
