What does the ち mean in this situation?


Why is Ms. Kobayashi's Dragon Maid written as 小林さんちのメイドラゴン instead of
小林さんのメイドラゴン? I'm still new to Japanese and I don't understand what the ち is
for in the title. Can it be written either way? I can't find any other pages
online that explain it. When an I supposed to use it?
