In New Hampshire, the duty to exercise due care to keep property safe for visitors and to remedy or warn of any known dangerous conditions extends to social hosts. That means your friend may be liable for any injuries you sustained if you fell because their property was unsafe. Many people are hesitant to ask friends for compensation, let alone pursue a lawsuit. Often, though, the friend’s homeowners’ insurance will cover the injury.
If your friend lives in an apartment building and you are injured due to dangerous conditions in a common area like a stairwell or hallway, the property owner/manager may be responsible.
