Mercury Insurance explains why a neighbor's mistake or a maintenance mishap could leave renters facing unexpected expenses
LOS ANGELES, Nov. 10, 2026 /PRNewswire/ -- Mercury Insurance (NYSE/NYSE TX: MCY) is helping renters understand a commonly overlooked financial risk: Damage to personal belongings doesn't always come from something they did wrong. An overflowing bathtub in the apartment upstairs, a kitchen fire in a neighboring unit or an accident during routine maintenance can damage or destroy a renter's possessions, raising a difficult question: Who pays when someone else causes the damage?
Many renters assume the person responsible; their landlord or another insurance company will automatically cover their losses. But determining responsibility and recovering compensation can be more complicated than expected.
"One of the biggest misconceptions about renters insurance is that if someone else causes the damage, their insurance will automatically take care of everything," said Lauren Lewis, Director, Underwriting at Mercury Insurance. "The reality is that responsibility and insurance coverage are two different questions. Having your own renters insurance can provide an important layer of financial protection when something unexpected happens."
When the Problem Starts Next Door
In apartments and other multifamily properties, an incident in one unit can quickly affect several others. Three common scenarios illustrate why renters should understand their insurance protection before a loss occurs.
The upstairs neighbor's overflowing bathtub
A tenant returns home to find water dripping through the ceiling after an upstairs neighbor accidentally leaves a bathtub running. The water damages a television, furniture and clothing.
Although the upstairs neighbor may have caused the incident, that doesn't necessarily mean they are legally responsible for every resulting loss. Whether the neighbor's liability insurance responds may depend on the circumstances, applicable law and policy terms.
A renter's own insurance may cover damage to personal belongings caused by certain sudden and accidental water incidents, subject to the policy's provisions, limits and deductible. However, not all water-related losses are covered, and flooding or damage from certain other sources may be excluded.
A fire in the apartment next door
A cooking accident in a neighboring apartment starts a fire. Flames never reach the renter's unit, but smoke and water used to extinguish the fire damage clothing, electronics and furniture.
The landlord's insurance may cover damage to the building, but it generally does not insure tenants' personal possessions. Even if another tenant caused the fire, establishing legal liability and obtaining reimbursement could take time.
Depending on the policy and circumstances, renters insurance may help pay to repair or replace covered belongings damaged by fire, smoke or related firefighting efforts. If the apartment becomes uninhabitable because of a covered loss, additional living expenses coverage may also help with certain temporary housing and other qualifying costs.
Damage during a maintenance visit
A maintenance worker or contractor accidentally damages personal belongings while performing repairs inside an apartment. Perhaps a plumbing repair results in water damage to furniture, or equipment falls and breaks an expensive television.
The renter may expect the property owner or contractor to pay for the damage. However, determining whether another party is legally responsible may require reviewing the circumstances, contractual obligations and applicable law.
A renter's insurance policy may provide protection for certain accidental losses, but coverage depends on the cause of damage and the policy's terms. Accidental damage to personal property is not automatically covered simply because another person caused it.
Who Caused the Damage Isn't Always Who Pays
Understanding the distinction between fault, legal liability and insurance coverage is essential.
Someone may have caused an accident without necessarily being legally liable for the resulting damage. Even when another party is responsible, their insurance coverage may be subject to exclusions, limits or other conditions.
A renter's own insurance may provide a more direct way to pursue coverage for an eligible loss without first establishing another person's liability.
"When your belongings are damaged, the last thing you want is uncertainty about where to turn," Lewis said. "Renters should understand what their policy covers, what it excludes and how their deductible works. That knowledge can make a meaningful difference when they need to recover from a loss."
If a renters insurer pays a covered claim, it may subsequently seek reimbursement from a legally responsible third party through a process known as subrogation. Any recovery depends on the circumstances and applicable law, and reimbursement of a policyholder's deductible is not guaranteed.
Five Ways Renters Can Better Protect Their Belongings
Mercury Insurance recommends taking several practical steps to prepare for unexpected property damage.
- Create a home inventory. Photograph or record furniture, electronics, clothing and other belongings. Save receipts for expensive purchases and keep a copy of the inventory somewhere accessible outside the apartment.
- Understand personal property coverage. Review policy limits, deductibles and whether belongings are insured on a replacement cost or actual cash value basis. These distinctions can significantly affect the amount received after a covered loss.
- Review exclusions and special limits. Standard renters policies generally exclude flood damage and may have limitations involving certain types of water damage, accidental breakage, jewelry, collectibles and other valuable property. Additional coverage may be available for some risks.
- Document damage immediately. When an incident occurs, take photographs, preserve relevant records and notify the landlord or property manager. Contact the insurance company promptly and take reasonable steps to prevent additional damage when safe to do so.
- Don't assume another person's insurance will cover the loss. Even when a neighbor, contractor or property owner appears responsible, renters should understand their own coverage options rather than relying solely on another party's willingness or ability to pay.
Protection Beyond the Apartment Walls
Renters insurance can offer more than protection for belongings inside a rental home. Depending on the policy, it may also provide personal liability coverage, protection for certain belongings away from home and additional living expenses when a covered event makes the residence temporarily uninhabitable.
For renters sharing an apartment, it's also important to understand who is actually insured. A roommate's policy generally does not automatically protect another roommate's belongings unless that person qualifies as an insured under the policy.
"The value of renters insurance isn't just about protecting against something you might accidentally do," Lewis said. "It's also about recognizing that you can't control everything happening around you. Understanding your coverage before an incident occurs can help you make more informed decisions about protecting the things you've worked hard to own."
Renters should review their coverage periodically, particularly after purchasing expensive items, moving to a new residence or experiencing changes in their living arrangements. An insurance agent can help explain available coverage options and identify potential gaps.
Insurance coverage is subject to the terms, conditions, exclusions, limits and deductibles of the applicable policy. Coverage for damage caused by third parties depends on the cause of loss, policy provisions and specific circumstances. Legal liability is determined by applicable law and the facts of each incident.
