When discussing construction or renovation, it is crucial to understand what guarantees the safety and durability of a structure. There is a significant gap between the ten-year warranty and the two-year warranty, often poorly understood by both individuals and construction professionals. Driven by strict regulations, these two types of civil liability cover very different aspects, but a proper understanding of them is essential to ensure that our real estate projects are protected against potential failures. In 2025, with the constant growth of the real estate sector and the challenges related to the quality of work, it is becoming urgent to decipher these protections and their legal implications for all stakeholders, from the builder to the project owner.
In the current context where the civil liability of builders, real estate developers, and construction companies is subject to increased scrutiny, the ten-year warranty occupies a central place. Also known as decennial liability, it requires professionals to be covered for 10 years after the completion of the work. But what are its real implications?
First and foremost, this mandatory insurance aims to cover major damage that compromises the solidity of the structure or renders it unfit for habitation. This particularly concerns major cracks, foundation settlement, and water infiltration, which, if not addressed quickly, can lead to serious structural failures.
Building companies must therefore take out this insurance to comply with building regulations, under penalty of heavy sanctions, or even withdrawal of their operating license. The key to success lies in perfect transparency on the often complex insurance contracts offered, and the ability to ensure legal monitoring.

If the ten-year guarantee relates to the solidity of the construction, the two-year guarantee, often also called a guarantee of proper functioning, has another objective. It mainly covers all elements of equipment which can be easily separated from the structural work. But why is it so important?
In practice, this legal responsibility concerns all these elements which do not compromise the structure of the building itself, but which contribute largely to its comfort and functionality. Think about doors, windows, electrical systems, radiators, or even wall coverings. If one of these elements fails within two years of receipt, the biennial insurance must intervene to repair or replace, without calling into question the integrity of the building.
This regime therefore allows rapid repair of equipment, avoiding excessive costs for the project owner. From a regulatory point of view, it is governed by article 1792-3 of the Civil Code, which requires transparency in the subscription of insurance contracts. However, this insurance does not cover the same extent as ten-year liability, which requires increased vigilance from professionals in the management of their guarantees.

It can sometimes seem difficult to differentiate between these two warranties, especially when you’re unfamiliar with the intricacies of building regulations. However, their distinction is crucial to avoid choosing the wrong coverage for a real estate project or to assess a claim.
In summary, the ten-year warranty focuses on the overall strength and compliance of the building. It covers, among other things, everything related to the structure, cracks, waterproofing, and even the impact on safety. It lasts 10 years from the date of completion of the work.
The two-year warranty, on the other hand, covers detachable and easily replaceable elements that do not compromise the structure. It is limited to these specific pieces of equipment and guarantees their proper functioning for two years. The table below provides a clear overview of their differences:
Criteria
| Ten-year warranty 🛠️ | Two-year warranty 🏠 | Duration |
|---|---|---|
| 10 years after acceptance | 2 years after acceptance | Type of damage covered |
| Building solidity, safety | Separable elements, operation | Examples |
| Cracks, collapses, major leaks | Doors, windows, radiators | Liability |
| Builder’s liability | Builder’s liability for equipment | Builders’ legal obligations under building regulations |
According to the building regulations in force in 2025, all professionals working in the sector must comply with a specific framework regarding insurance and liability. Whether for new construction or renovation, all construction companies must ensure their compliance with the law.
In practice, this means that any builder involved in the delivery of a building must take out ten-year insurance, failing which they are exposed to significant criminal and financial penalties. Similarly, taking out structural damage insurance is strongly recommended to protect the interests of the project owner against the liability of the project manager.
Failure to comply with these obligations can result in the suspension of activities, the withdrawal of the building permit, or even substantial fines. The key to complying with these building regulations lies in regularly monitoring legal developments, accessible with this practical article.
