What is third-party liability insurance?

Third-party liability insurance means that when an insured person causes property damage or personal injury to a third party due to an accident, the insurance company will cover the insured person's liability for compensation and litigation costs, and will also handle legal negotiations on behalf of the insured person.

What does third-party liability insurance cover?

Third-party liability insurance covers legal liability for injuries or property damage to others caused by personal negligence in daily life, including litigation costs, legal fees, expert report fees, etc.

Who is not considered a "third party"?

  • Policyholder
  • The insured's spouse
  • Family members living with the insured
  • Foreign domestic helper hired by the insured

Scope of Third-Party Liability Protection in Home Furnishings

Liability for accidentally falling objects

Home Insurance typically covers personal injury and property damage caused by accidents, including aluminum windows flying off home windows, falling decoration materials injuring passersby, or causing property damage, and the insurance will pay the relevant compensation.

Leaking water damages the neighbor's property

If a unit experiences a water leak due to a burst pipe or negligence in the water supply system, causing damage to the ceiling of the unit below or in a neighboring unit, or even to external public facilities, home insurance can usually cover the repair and compensation costs of water supply equipment.

Electrical appliances accidentally affect others

If a fire is caused by an electrical malfunction in your home and affects others, it is covered by third-party liability insurance. The insurance will compensate for personal injury or property damage caused to third parties by an accident involving a household appliance in your residence.

Property loss caused by pets

Some home insurance policies cover pet-owning households. If a pet bites someone or accidentally causes property damage to a third party, compensation can be claimed through third-party liability insurance.

Accidental damage to public facilities

If damage occurs in a residential building or common area, such as an elevator or corridor, and the cause is a home accident, the insurance will cover the relevant compensation costs.

Medical expenses for accidental injuries sustained by visitors

If the insured or their family members living in the unit are injured due to the negligence of the visitor, such as being hit by falling objects or slipping on a wet floor, the third-party liability insurance will also cover the medical expenses incurred.

Are landlords legally liable after renting out their units?

Third-party liability insurance for homeowners

Even when a unit is rented out, legal responsibility doesn't solely fall on the tenant. The landlord may also be liable for injuries to third parties or accidents affecting the unit. Third-party liability insurance can cover bodily injury or property damage caused to third parties due to accidents, such as structural defects like ceiling leaks or concrete peeling that result in injury or property damage to tenants or neighbors. However, this coverage only applies to third-party liability and does not cover losses incurred by the landlord due to tenants being overly aggressive.

Homeowner Insurance

If landlords require an insurance plan specifically for their rental units, they can opt for landlord insurance that includes third-party liability coverage. Landlord insurance primarily protects landlords against situations such as tenants maliciously withholding rent, damage to property caused by vandalism, and legal costs incurred in recovering rent and reclaiming the property.

Home renovation insurance with third-party liability coverage: Should the homeowner or the renovation company buy it?

Third-party liability insurance coverage for home renovation

Third-party liability insurance for renovation projects, also known as public liability insurance, protects the contractor, owner, or tenant against legal liability arising from accidents during the renovation period that cause personal injury or property damage to third parties. Examples of such accidents include accidentally drilling through a neighbor's wall, accidentally damaging pipes, or inadvertently injuring passersby while erecting sheds.

Is it mandatory to buy third-party liability insurance for home renovations?

Although third-party liability insurance for renovations is voluntary, most property management companies or owners' corporations require owners or contractors to purchase third-party liability insurance before approving renovation work.

Do homeowners need to purchase third-party liability insurance for home renovations themselves?

Homeowners can purchase insurance for their renovation projects themselves. Some renovation companies also offer third-party liability insurance and damage to construction materials insurance, including the premium in their quotes. If homeowners choose third-party liability insurance purchased by the renovation company, they must understand the insurance arrangements and costs, and confirm that the policy lists the information of both parties and that the coverage extends to the homeowner. Otherwise, homeowners should purchase their own insurance and be aware of the coverage scope and validity period.

Common exclusions of third-party warranty for home renovation

Building age restrictions

Most third-party renovation insurance policies have age restrictions, typically only covering buildings under 40 years old. Because older buildings are often in disrepair, the risk of damage during renovations is higher. Therefore, buildings over 40 years old may require insurance company review for coverage, and even if covered, may incur higher deductibles or additional premiums.

scaffolding and exterior wall work

Due to the high risks and dangers associated with scaffolding and exterior wall construction, most third-party liability insurance policies for renovations do not cover these projects. If scaffolding work is required, insurance companies typically require additional premiums and limit the cost of exterior wall work, such as not exceeding 15% of the total project cost. Furthermore, even when some insurance policies cover scaffolding and exterior wall work, they usually only cover accidents occurring while using the scaffolding; accidents occurring during the erection or dismantling of the scaffolding are not included. Therefore, careful consideration of all coverage terms is essential when purchasing insurance.

Works outside the construction period or quotation

Home renovation insurance typically specifies the construction period, also known as the "coverage period." If the project needs to be extended, the policyholder must notify the insurance company to extend the coverage period and pay an additional premium to continue receiving coverage. Because renovation insurance premiums are based on the scope of the renovation, if work beyond the initial quote is performed during the construction period, the insurance company has the right to refuse compensation.

Illegal construction or works not approved by the Buildings Department

Most renovation and third-party liability insurance policies explicitly exclude illegal alterations, unauthorized additions, and unapproved construction projects from coverage. If an accident or third-party injury or death occurs during renovations due to illegal structural elements, such as alterations to main walls, unauthorized additions to terraces or platforms, the insurance company has the right to refuse compensation. Construction work carried out without approval is an illegal act. Upon conviction, they are liable to a fine of HK$400,000 and imprisonment for two years.

Frequently Asked Questions

If the renovation worker has already purchased "labor protection insurance," does the homeowner still need to purchase "renovation third-party liability insurance"?

Even with labor insurance, homeowners still need to purchase "renovation third-party liability insurance." Labor insurance only covers the legal liability for injury or death of workers due to accidents during the construction period. It does not cover the legal liability for injuries to neighbors, damage to public property, or damage to third-party property caused during the renovation period. Therefore, it is necessary to purchase renovation third-party liability insurance and renovation project insurance.

If I'm only doing simple interior painting, do I still need to buy third-party liability insurance for renovations?

Although there is no legal requirement to purchase third-party liability insurance for renovations, it is strongly recommended that homeowners or tenants purchase it for added protection. Even with simple painting work, accidents can still occur, such as strong paint fumes causing discomfort or allergies to third parties, or accidentally soiling neighbors' property during the painting process.

If the company already has "home insurance," is there any third-party liability protection during renovations?

Most home insurance policies on the market do not adequately cover home renovation projects. Since home insurance is not specifically designed for renovations, the "third-party liability protection" coverage generally only compensates for third-party liability caused by the negligence of the insured, their family members, or domestic helpers; losses caused by the renovation contractor are not covered. Therefore, homeowners need to purchase separate "renovation project insurance" or "home renovation insurance" when renovating.

If a water leak in one unit causes damage to the building's elevator, is compensation handled by the building corporation's third-party insurance company?

No. The building's third-party insurance only covers accidents caused by the corporation's negligence in the building's common areas. If the leak is in your private unit, the liability for compensation falls on you, and you will need to cover the cost using your own home insurance.

I am a tenant. If I accidentally start a fire that affects my neighbors, will the landlord's insurance cover me?

Generally not. Since homeowners' home insurance and fire insurance usually only cover the property and structural safety of their own unit, if a tenant causes a fire due to improper use of appliances and it spreads to neighbors, the tenant will be responsible for the property damage and legal liability caused to neighbors due to their negligence in causing the fire.
