As the homeowner, how can I remove the liability arising from any accident incurred by an attendee of a party that is being held on my premises?
The party attendees are the friends of the daughter of my tenant.
A homeowner is responsible to keep his surroundings safe and accessible. In the wintertime, he should keep his walkway and driveway shoveled and free from snow and ice. In the summertime, he should keep it free from toys, bicycles, weeds, and water.
Inside the home, he should protect the inhabitants of the home and any visitors from harm as well. Stairways should be well-lighted, steps free from objects that could be tripped over, and equipped with safety and/or handrails to prevent falls. Tile, marble, or wooden floors should be kept clean and dry. If they are excessively slick, they should be covered by rugs to prevent falls. Furniture should be placed in such a manner to allow free movement around the rooms. Any sharp corners should be covered by protective cushions or throws. Handles on doors should be easy to turn.
A homeowner has to perform routine maintenance on his home to insure it meets the safety requirements for his area. Electrical fixtures and lighting must be checked periodically to make sure there is no loose or worn wiring that could cause electrical shock or fire.
In the case of a party being held by the daughter of your tenant, I would make sure you lay down certain rules to be observed in your home. Even though they are living there, it is still your home. If you don't want them doing drugs or liquor, it is your right. Alcohol impairs the judgment of anyone, especially young people, and they're more likely to damage things or get hurt when they're inebriated. The parents of the daughter also need to instruct their daughter in what's proper behaviour to protect both the home and her friends. Then, the attendees of the party need to be instructed in their duties when they arrive so that they have clear guidelines to follow to insure their safety and the preservation of the home.
If all precautions are taken and everyone understands their duties and responsibilities, there will be less likelihood of accidents happening and liabilities arising.
