Do you need to take out defects insurance before starting a rehabilitation project?

Rehabilitation projects represent a substantial investment and carry their share of potential risks. Construction defects insurance is mandatory for any project owner before the start of construction or major rehabilitation work. It guarantees pre-financing of repairs for damage covered by the ten-year warranty, without waiting for a court decision to determine responsibilities. This legal obligation deserves precise clarification to understand its application and implications.

The legal framework of construction defects insurance

Construction defects insurance is based on the Spinetta Act of January 4, 1978, amended by several subsequent texts. This legislation profoundly transformed the construction sector in France by establishing a system of mandatory insurance.

The Civil Code, in its articles 1792 and following, defines the responsibility of builders and applicable guarantees. Article L242-1 of the Insurance Code explicitly requires subscription to defects liability insurance for any natural or legal person having construction work carried out.

The work covered by this obligation

Not all rehabilitation projects are subject to the obligation to take out defects liability insurance. The distinction is based on the nature and scope of the work carried out.

• Major structural work affecting the building structure (load-bearing walls, roof framework, foundations)
• Substantial modifications to the existing structure rendering the work unfit for its intended purpose
• Extensions creating a new surface area greater than 20 m²
• Raising of buildings and additions to construction
• Major renovations including the replacement of indissociable equipment elements

Conversely, maintenance, decoration or simple repair work generally do not fall within the scope of this compulsory insurance. A fresh coat of paint, a change of floor covering or the replacement of equipment do not require this specific coverage.

The guarantees and protection offered

Defects liability insurance is distinguished from other construction insurance by its triggering mechanism and its terms of intervention. Its main function is to accelerate compensation to the building owner in the event of loss covered by the ten-year guarantee.

How pre-financing works

Unlike the ten-year civil liability insurance taken out by builders, defects liability insurance intervenes without prior investigation of liability. As soon as a covered defect is established, the insurer has 60 days following notification to propose a repair solution or pay compensation.

This speed of intervention constitutes the major advantage of this insurance. It spares the owner from embarking on lengthy legal proceedings to obtain compensation, proceedings that can extend over several years.

The consequences of not having insurance

Failing to take out construction defects insurance when it is mandatory exposes the project owner to several legal and financial risks with potentially serious consequences.

Criminal and administrative penalties

Failure to comply with this obligation constitutes an offense punishable by a fine of up to €75,000 for an individual and €375,000 for a legal entity. Beyond the financial aspect, this violation can cause complications when selling the property.

The absence of a construction defects insurance certificate can make a property difficult to sell, as potential buyers and their banks systematically require this document for recent constructions.

In case of a claim, the absence of construction defects insurance requires the owner to engage in lengthy and costly court proceedings to obtain compensation. They must prove the responsibility of the contractors, which often requires expensive technical assessments and can take several years.

Cost and subscription terms

The price of construction defects insurance varies considerably depending on several parameters related to the rehabilitation project. Insurers assess the risk based on objective criteria before providing their proposal.

Factors influencing the price

• The nature and scope of the work undertaken
• The total amount of the rehabilitation project
• The geographical location of the property (seismic zones, flood-prone areas)
• The qualifications and references of the companies involved
• The existence of technical inspection or an engineering firm

On average, the cost of this insurance represents between 2% and 5% of the pre-tax amount of the work. For a rehabilitation project of 100,000 euros, a budget of between 2,000 and 5,000 euros must therefore be planned for this coverage.

The subscription must take place before the work begins. Insurers generally require a complete file including plans, detailed quotes, insurance certificates from companies and possibly a technical inspection report. This process requires an instruction period which can vary from a few days to several weeks depending on the complexity of the project.

Potential difficulties in obtaining it

Certain situations can complicate the subscription of defects insurance. Projects involving innovative or non-conventional construction techniques may encounter insurance refusals or significant additional premiums.

Rehabilitation of old or listed buildings also present peculiarities that sometimes make it difficult to obtain this coverage under standard terms. In these cases, there are specialized insurers, but their rates are generally higher.

Special cases and exemptions

Although the obligation is the general rule, certain specific situations benefit from a special regime or an exemption from the defects insurance obligation.

The State and local authorities are exempt from this obligation, as these public entities have their own self-insurance capacity. Similarly, work carried out by an individual for themselves, without professional intervention, are exempt from this requirement, although they remain subject to legal guarantees.

Real estate and construction professionals strongly recommend taking out this insurance even in cases where it is not strictly mandatory, as it constitutes valuable financial protection in case of problems.

For rehabilitation work of limited scope, the boundary between obligation and discretion can seem blurred. In case of doubt, it is recommended to consult a specialized broker or a construction lawyer to obtain a precise analysis of the situation.

Secure your rehabilitation project

Taking out defects insurance before the start of a rehabilitation project is not merely an administrative formality. It represents essential protection for the owner and a pledge of seriousness towards all project stakeholders.

Beyond the mandatory aspect for major works, this insurance provides considerable peace of mind. It guarantees that in the event of a serious problem affecting the building, repairs will be financed quickly without having to wait for the outcome of legal proceedings.

To optimize your protection, make sure to choose an insurer recognized in the construction field, to carefully check the contract exclusions, and to build a complete file from the start of your project. This anticipation will greatly facilitate the process and allow you to start your rehabilitation project serenely in full legal compliance.
