DOG BITE AT A HOME: If I was hired to perform work at a person's house, and their dog bit me causing me injuries, do I have a legal claim against the homeowner?

Yes, in most cases, if you are asked into a house (or onto property) to perform work for someone, the person who owns the property has a legal responsibility to take reasonable efforts to protect you from injury he or she knew about, or should have known about.

However, California law has "strict liability" law protection for dog bites; which means you only have to show the dog bit you causing you injury.  Thus, if the person has a pet, like a dog, the person might be responsible for keeping the pet away from you, or at least warning you of the presence of the animal, and for any bites that result by the fact you were in the presence of the dog. Note that you may also have a workers' compensation claim against your employer. Because every case is unique, however, you should consult an attorney for further clarification.
