Building or renovating a house, cottage, or garage is much more than just a real estate project. It's often a lifetime investment. To complete this type of project without any unpleasant surprises, it's essential to fully understand all the necessary protections, particularly regarding liability insurance.
At Plan Maison Québec, we assist hundreds of families and homeowners each year in designing custom plans for their construction or renovation projects. Beyond the quality of our plans, we strive to inform our clients of the essential precautions to take before work begins. One of the most overlooked, yet crucial, aspects is liability insurance. This article aims to shed light on this concept to help you avoid pitfalls and unforeseen events.
Understanding civil liability: essential protection
Civil liability is a legal concept that refers to a person's obligation to repair the damage they cause to others. In the residential context, this means you could be held liable if someone suffers bodily injury or property damage because of you, whether at your home, on your construction site, or elsewhere.
In concrete terms, if a passerby is injured by tripping over materials left on your property during construction, or if one of your trees falls on your neighbor's roof during a storm, you may have to pay the costs associated with the damage. Civil liability insurance then covers you to avoid having to pay these amounts out of pocket.
The vast majority of home insurance policies in Quebec automatically include civil liability protection. However, this coverage may not be sufficient to cover all the risks associated with a major construction or renovation project. That's why it's essential to ask yourself the right questions before starting work.

Why is civil liability so important during construction?
A construction or renovation project generally involves the presence of numerous stakeholders on the construction site: architects, designers, contractors, workers, and inspectors. Each of these stakeholders operates equipment, performs potentially dangerous operations, and can, despite their best efforts, cause damage to a third party or property.
Imagine, for example, that excavation work for your future garage accidentally damages the foundations of a neighboring property. If you are found liable, the repairs could cost tens of thousands of dollars. If you don't have sufficient coverage, you will have to bear these costs.
At Plan Maison Québec, we work upstream to minimize risks. Our plans are designed according to current standards, respecting technical and urban planning constraints. However, despite all this planning, it is impossible to completely eliminate the risk of accidents or unforeseen damage. Hence the importance of good liability insurance.

The limits of standard liability insurance
Most home insurance policies offer basic liability coverage of around $1 million. This may seem high, but in the event of a serious accident—such as a serious worker injury or significant structural damage—this amount may not be enough.
Additionally, there are some exclusions that are important to know about. Standard liability insurance generally does not cover:
Intentional damage.
Illegal or criminal acts.
Professional activities (if you work from home, for example).
Damage to your own property.
Therefore, if you carry out the work yourself or hire friends or family members to help you, you may not be covered in the event of an accident. It is therefore strongly recommended that you speak to your insurer to assess whether you need an extended warranty or temporary builder's insurance specific to your project.

Ensure the work, but also the participants
Another important aspect to consider is the liability of the contractors you hire. You must ensure that all professionals involved in your project have their own liability insurance. This protects you in the event of an error or negligence on their part.
At Plan Maison Québec, we always recommend our clients request proof of insurance from contractors before entrusting them with any work. This is an essential step to avoid liability in the event of a problem. A reputable company will not hesitate to provide you with this document.
Furthermore, if you are acting as a self-builder, meaning you manage your own project, you must be even more vigilant. As the project manager, you could be held liable for any incident that occurs on the site, even if it is not directly your fault.

Civil liability and temporary rental
Some owners choose to rent out their residence during the renovations or to live elsewhere temporarily. In these cases, the issue of civil liability becomes even more complex. If you rent a property, you must ensure that your tenant's insurance adequately covers you for any damage you may inadvertently cause in your new location.
Conversely, if you leave your property vacant for several weeks while the renovations are being carried out, you must notify your insurer. An unoccupied home represents an increased risk of loss (theft, vandalism, fire, etc.), and a prolonged absence could void certain coverages if it has not been reported.
This type of detail may seem trivial, but it is essential to avoid unpleasant surprises in the event of a loss. Once again, communication with your insurer is key.
The importance of prevention and good planning
While liability insurance is essential financial protection, it never replaces prevention. At Plan Maison Québec, we firmly believe that safety begins with the planning stage. A well-thought-out, standards-compliant plan significantly reduces the risk of accidents or disputes.
That's why we offer a personalized design service based on a comprehensive analysis of your needs, your site, and local regulatory constraints. This rigor in our approach allows our clients to start on a solid foundation and reduce areas of uncertainty.
By partnering with Plan Maison Québec, you benefit from a team familiar with the realities of Quebec's landscape, provincial construction standards, and best practices to ensure the success of your project, from the first sketch to completion.

Conclusion: Be well protected with Plan Maison Québec
In short, liability insurance is an essential component of any construction or renovation project. It protects you against the financial consequences of an accident or damage caused to others, and provides you with valuable peace of mind throughout your project.
However, this insurance is only effective if it is well understood and adapted to your situation. Each project is unique, which is why it is essential to assess your specific coverage needs. Don't assume your current policy is sufficient without discussing it with a professional. At Plan Maison Québec, our mission goes far beyond drawing up plans. We want your project to be a success on every level—functional, aesthetic, and safety-wise.
