Pesach Questions

What are my obligations regarding chametz if I am housesitting for someone throughout Pesach?

You only need to sell chametz that you yourself own. You are not responsible for the chametz in the house you are housesitting, but the owners of c​ourse are. You should still make sure to do bedikat chametz in your own home. When doing so, you should say the bittul but not the bracha. Then on Erev Pesach when you are in the home in which you are housesitting, you can say the final bittul. If you are using any of the kitchen utensils in the housesitting home, you would need to make sure they are kashered for Pesach. If you (or the owners) are not kashering the kitchen for Pesach, and you choose to eat kosher lePesach cereal or something that does not need to be cooked, you may use disposable plates/bowls/cutlery/etc. Just make sure the surface you eat on (table, etc) is thoroughly cleaned so no chametz can get into your food. MATN
