If you were sexually assaulted on a property such as a hotel, in a parking lot, or at an apartment building, you may also have a case against the owner of the property if you can prove that negligent security contributed to your injuries. Negligent security means the failure to provide a reasonable level of security in response to the known level of threat/danger.
For example, it is reasonable to expect the owner of your apartment building to provide a door that locks with a deadbolt, or for the owner of a hotel to secure the hotel with video footage, and perhaps a security guard. If you can prove that the owner of the property breached the duty of care owed to you by failing to provide reasonable security, and that the lack of security contributed to the incident of sexual assault, the property owner may be held partially liable for your damages.
